This research aims to analyze the spatial price transmission and market integration of significant groundnut markets in Ethiopia, utilizing monthly retail price data from September 2000 to August 2022. A combination of descriptive and econometric methods was employed for the analysis. The descriptive statistics indicated that consumption areas exhibited the highest nominal mean prices, with Dire Dawa and Addis Ababa reporting ETB29.89 and ETB28.69 per kilogram, respectively, whereas the producing regions showed the lowest average prices for groundnuts. The Augmented-Dickey Fuller test was used to test for the stationarity of individual price series and was confirmed by the KPSS test. All the price series data that were used tested for Unit Root. They were found to be non-stationary at levels but stationary after first difference at 1%, 5% and 10% significant levels. Johansen Co-integration test was used to test for long- run relationships between the market pair.It was found that all six market pairs were cointegrated at 5% level of significance. The Non-linear Auto Regressive Distributed Lag Model shows asymmetric price transmission in two market pairs, indicating quicker adjustments to price increases than decreases. The study implys the influence of geographical differences, distance, and production volume on market integration. This study provides significant contributions to the formulation of agricultural marketing policies and deepens our comprehension of market dynamics in Ethiopia. groundnut market integration non-autoregressive distributed lag model price transmission Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Introduction In countries where agriculture is the primary economic activity, particularly in the majority of sub-Saharan Africa, the agricultural sector and its related industries play a crucial role in fostering economic development and alleviating widespread poverty and food insecurity. In sub-Saharan African countries, among the crop types produced, groundnuts ( Arachis hypogeas L.) are an essential crop, and the fifth most widely cultivated crop in sub-Saharan Africa, following maize, sorghum, millet, and cassava FAO (2010) holds significant importance within the agricultural landscape of Ethiopia. Although it ranks as the second-most essential oilseed crop after sesame (Amare et al., 2017 ), its primary production is concentrated in the eastern regions of the country. The 2020 cropping season witnessed an estimated production of 205,069 tons from approximately 113,515 hectares, with a productivity of 1.8 tons per hectare (Debele et al., 2023 ). Strong connections to markets are being increasingly acknowledged for their role in poverty alleviation, food security, and rural community advancement within the agricultural sector (Livingston et al., 2011 ). Organizations and development experts prioritize market interaction as a means to enhance agricultural output, foster economic growth, and diminish poverty and hunger among rural producers. This emphasis on market connections impacts food security, income levels, and overall productivity, creating a positive feedback loop that motivates small producers to invest in their businesses, enhance output quality, and diversify product lines (Livingston et al., 2011 ). Agricultural markets and access to market information are crucial for the effective engagement of smallholder farmers in agricultural markets (Magesa et al., 2014 ). Smallholder farmers, particularly those involved in groundnut production, encounter challenges in accessing vital market information, such as commodity pricing in local markets (Ross and de Klerk, 2012 ). This limitation significantly impacts the farmers’ ability to make informed and profitable trading decisions, inhibiting their capacity to exploit seasonal and spatial arbitrage opportunities. The absence of accurate market price information often compels smallholder farmers to accept the prices offered by buyers, thus compromising their marketing decisions. In integrated markets, food commodities flow from surplus to deficit areas. Deficit areas, typically associated with high prices, create an incentive for traders to transport food from surplus to deficit areas (Abay et al., 2023 ). Rational traders enter the market and capitalize on these arbitrage opportunities by increasing demand for the commodity in surplus areas while simultaneously boosting the supply of the commodity in deficit areas. This process continues until prices in both markets reach an equilibrium level, rendering trade unprofitable (Lupiya, 2018 ). This study analyzes the process characterized as asymmetric, where the transmission of price changes varies depending on whether prices are rising or falling. It is frequently claimed that traders leverage their market power to implement pricing strategies that facilitate a swift and comprehensive pass-through of cost increases, while the transmission of cost reductions occurs more slowly and is less complete (Kinnucan and Forker, 1987 ). 1.1. Asymmetry in Price Transmission When the response of market at one level responds differently to a decrease and increase in price at a different level, then asymmetry exist. Asymmetry could exist in the magnitude or the speed of adjustment or both. In the former, short-run elasticities of price transmission differ according to the sign of the initial change while in the latter, long-run elasticity differ (VonCramon-Taubadel, 1998 ). Asymmetry can also be classified as positive (when one price responds fully or quickly to an increase in another price as to a decrease, thus price movement that squeezes the margin is transmitted more rapidly and/or completely as the movement that stretches the margin). Otherwise, negative (when one price responds fully or quickly to a decrease in another price than to an increase; thus rapid and/or complete transmission to price movements that stretch the margin). This determines the direction of welfare transfer (Meyer and von Cramon-Taubadel, 2004 ). Asymmetry can also be considered to be vertical if determined along the food supply chain (e.g. from farm level to wholesale level) or spatial when determined between two geographically separated markets. Asymmetric price transmission has long been associated with agricultural prices with the idea starting from Tweeten and Quance ( 1969 ) that used dummy variable to split input prices into increasing and decreasing input prices. Following this, studies such as Acharjee et al., ( 2023 ) suggest that the price transmission pattern is symmetric in the short run but could be a mixture of symmetric and asymmetric in the long run. This asymmetric price behavior indicates that changes in retail prices do not get reflected fully at both farmgate and wholesale prices, and the transmitted prices may vary according to the retail prices based on their rising or falling pattern. These studies, however, predated the development of cointegration and did not consider the problems related to nonstationary series (Hassouneh et al., 2012 ). Granger and Lee ( 1989 ) therefore incorporated the variable splitting technique into the error correction representation to correct for the problem of nonstationarity. Since then, variants of this approach have been used extensively in applied work (von Cramon-Taubadel and Loy, 1996 ). Other studies Abdulai ( 2000 ); Enders and Granger ( 1998 ) and Enders and Siklos ( 2001 ) also have captured asymmetry using threshold models, where price movements above or below certain thresholds trigger different response. A number of potential causes but limited have been attributed to asymmetries in price transmission. Among studies addressing this issue include (Meyer and von Cramon-Taubadel, 2004 , 2004 ,Frey and Manera, 2007 and Abdulai, 2000 ). Some of the potential causes of asymmetry discussed in literature include market power. Market power refers to the ability of an enterprise or a group of enterprises to raise and maintain price above or below a competitive level (Amonde et al., 2009 ). In non-competitive market structure where there is considerable degree of market power, market agents react quickly and/ or more completely to shocks that squeeze their marketing margin than to corresponding shocks that stretches them, resulting in positive asymmetry. Positive asymmetry is, however, not the only resulting effect of market power. Ward ( 1982 ) indicates that oligopolists can be reluctant to increase market prices for the risk of losing market share. The positive asymmetry appears to be reasonable in pure monopoly while both positive and negative asymmetries are conceivable in the more common oligopolistic context (Meyer and von Cramon- Taubadel, 2004). Frey and Manera ( 2005 ) also present a comparable argument regarding tacit collusion in oligopolistic markets. In this scenario, when wholesale prices rise, firms promptly raise their selling prices as a signal to their competitors, indicating their compliance with the tacit agreement. Conversely, when wholesale prices decrease, firms are cautious in adjusting their prices, as doing so may risk signaling a reduction in their profit margins and deviating from the agreement. Adjustment/menu costs are another factor that contributes to the presence of asymmetry. These costs are incurred by firms when they decide to alter the quantities and/or prices of their inputs and/or outputs. When these costs are specifically related to price adjustments, they are referred to as menu costs (Meyer and von Cramon-Taubadel, 2004 ). Menu costs encompass various expenses such as the cost of modifying nominal prices, printing catalogues, dealing with inflation-related costs, and disseminating information regarding price changes. It is worth noting that these costs may exhibit asymmetry in relation to price increases and decreases. Methodology 2.1. Study area and data sources The Study was primarily examined four specific areas in Ethiopia: Oromia (Jima), Benishangul-Gumuz (Asosa), Amhara (Este), Central Ethiopia Regional State (Sawla), Diredawa, and Addis Ababa. These regions are part of the Twelve Regions of Ethiopia, with Addis Ababa serving as the nation's capital and Diredawa as a municipality. While Addis Ababa and Diredawa are considered consumption hubs, the four regions mentioned are recognized as significant groundnut production zones. Among them, Oromia Region stands as the largest groundnut producer, followed by Benishangul-Gumuz, according to the (Sendekie, 2023 ). The markets that are studied in the Oromia region was Jima, while in the Amhara region was Este, BenishengulGumuz region was Asosa and SNNPR regions, Sawla markets was studied. These markets were surplus markets, and markets in deficit areas that were studied include the Diredawa market and the Addis Ababa market. The criterion for selecting these markets is based on net market positions (surplus and deficit), geographical distribution, data availability and the volume of trade or the importance of the market to the national Groundnut trade flow. 2.2. Source of Data The study used secondary time series data that was collected from the Ethiopian Statistical Service (ESA) of Ethiopia, covering the period September 2000 -August 2022. The monthly retail prices that are deflated and seasonally adjusted to cater for inflation during the period of study were used. 2.3. Econometric Model The examination of time series data involves several critical procedures, one of which is the verification of the stationarity of research variables, ensuring that none exhibit integration beyond the second order. Consequently, it is essential to analyze the unit root properties of the variables utilized in the study. The presence of multiple orders of integration within a variable can lead to misleading results. To assess the order of integration of the variables, we employed the Augmented Dickey–Fuller (ADF) and Phillips–Perron (PP) unit root tests prior to the application of the time series econometric model. Additionally, before investigating causality, it is crucial to evaluate the cointegrating relationships among the variables. We implemented the Bounds cointegration test to determine whether any cointegration exists between the variables. The NARDL Model The study employed the NARDL approach to examine the asymmetric price transmission between markets experiencing surplus and those in deficit, specifically focusing on the relationship concerning groundnut prices. The Non-linear ARDL model recently developed by Shin et al., ( 2014 ) uses positive and negative partial sum decompositions allowing detecting the asymmetric effects in the long and the short-term. Compared to the classical cointegration models, NARDL models present some other advantages. Firstly, they perform better for determining cointegration relations in small samples (Romilly et al., 2001 ). Secondly, they can be applied irrespective of whether the regressors are stationary at level or at the first difference (i.e. I(0) or I(1)). They cannot be applied however if the regressors are I(2). Therefore, the asymmetric NARDL framework of Greenwood-Nimmo and Shin, ( 2013 ) is particularly suitable for our research problem as it allows us not only to gauge the short- and long-run asymmetries, but also to detect hidden cointegration \(\:{\varDelta\:\varvec{P}}_{1\varvec{t}}=\:{\partial\:}_{0}+\:\sum\:_{\varvec{i}=1}^{\varvec{n}}{{\varvec{\rho\:}}_{1}\varDelta\:\varvec{P}}_{1,\varvec{t}-1}\) + \(\:\sum\:_{\varvec{i}=1}^{\varvec{n}}{{\varvec{\rho\:}}_{2}\varDelta\:\varvec{P}}_{2,\varvec{t}-1}\) + \(\:{\varvec{\beta\:}}_{2}^{+}{\varvec{E}\varvec{C}\varvec{T}}_{\varvec{t}-1}^{+}\) + \(\:\:{\varvec{\beta\:}}_{2}^{-}{\varvec{E}\varvec{C}\varvec{T}}_{\varvec{t}-1}^{-}\) + \(\:\:{\varvec{\epsilon\:}}_{\varvec{t}}\) \(\:{\varDelta\:\varvec{P}}_{2\varvec{t}}=\:{\partial\:}_{1}+\:\sum\:_{\varvec{i}=1}^{\varvec{n}}{{\varvec{\rho\:}}_{1}\varDelta\:\varvec{P}}_{1,\varvec{t}-1}\) + \(\:\sum\:_{\varvec{i}=1}^{\varvec{n}}{{\varvec{\rho\:}}_{2}\varDelta\:\varvec{P}}_{2,\varvec{t}-1}\) + \(\:{\varvec{\beta\:}}_{2}^{+}{\varvec{E}\varvec{C}\varvec{T}}_{\varvec{t}-1}^{+}\) + \(\:\:{\varvec{\beta\:}}_{2}^{-}{\varvec{E}\varvec{C}\varvec{T}}_{\varvec{t}-1}^{-}\) + \(\:\:{\varvec{\epsilon\:}}_{\varvec{t}}\) \(\:{\:\varvec{E}\varvec{C}\varvec{T}}_{\varvec{t}-1}^{+}+\:{\varvec{E}\varvec{C}\varvec{T}}_{\varvec{t}-1}^{-}=\:{\varvec{E}\varvec{C}\varvec{T}}_{\varvec{t}}\) , the standard symmetric VECM is nested in the AVECM and the F-test to test the null hypothesis of symmetry \(\:{\varvec{H}}_{0}\) : \(\:{\varvec{\beta\:}}_{2}^{+}=\:{\varvec{\beta\:}}_{2}^{-}\) . If this is rejected then price transmission process among the market is asymmetric. The F -statistic value for the non-linear ARDL falls between the upper and lower bounds, it implies that the relationship between Change in price and its determinants is inconclusive. However, for the asymmetric NARDL, bounds test result shows that there is evidence of cointegration among Diredawa-Este, Diredawa-Jima, Diredawa-Sawla, Diredawa-Asosa, Addis ababa-Este, Addis ababa-Jima, Aaddisababa-Sawla and Adis ababa-Asosa Market.

This variability can be attributed to a range of factors, including natural influences like weather fluctuations, as well as economic factors such as transportation expenses, market participants, and alterations in marketstructure. According to Table 1 , Diredawa and Addisababa exhibited the highest nominal mean prices at 29.89 and 28.69 ETB per Kg respectively, whereas Asosa and Este showed the lowest mean prices at 13.49 and 22.83 ETB respectively. The high prices in both Diredawa and Addisababa were as a result of urban demand of groundnuts that outpaced supply (Bayata and Nega, 2020 ). The low prices recorded in Asosa, Sawla and Este can be attributed to the fact that the markets are located in the main groundnut growing regions across the country. The variations in nominal groundnut prices in regions with both shortages and excesses are depicted in Figures (1) and (2) below. Prices in Diredawa and Addisababa were notably higher compared to those in the areas where groundnuts are produced, leading to a more distinct graphical representation. Overall, a consistent price pattern has been observed in all six markets, indicating that groundnut prices have moved in the same direction throughout the years. These findings support the conclusions of Lupiya, ( 2018 ) who demonstrated a national upward trend in groundnut prices. Upon visual examination, it is evident that prices have continuously increased, suggesting a potential spatial integration of markets in regions with both shortages and excesses. 4.1.

On the other hand, triple, double and single asterisks for the KPSS show significance at all levels, two levels and one level respectively. The critical values for the ADF at 1, 5 and 10 percent levels are − 3.465, -2.877 and − 2.575 respectively. The critical values for the KPSS are 0.739, 0.463 and 0.347 at 1, 5 and 10 percent respectively. Source: Own computation from Retail price data (2000–2022) Prices at the six markets were all stationary after the first difference. Since all variables were stationary after first difference, meaning that they were integrated of order1, that is to say I (1). This is one of the conditions for testing co-integration that depicts the existence of a long-run relationship among the six groundnuts markets. Similarly, Kwiatkowski Philips Schmidt Shin (KPSS) found the same results with ADF tests. That is since the value of KPSS test statistics for the first difference of all market price series is smaller than the critical value at the 0.01 level of significance. We fail to reject the null hypotheses of stationarity at the 1% level of significance. This implies that the first differenced series of the all market are stationary. Assymetric cointegration test for Diredawa- Este market F bound test Upon verifying the order of integration, the next step involves examining the cointegrating properties of the variables. We employed the Bounds cointegration tests, utilizing both F statistics and t statistics, to determine the presence of cointegration among the variables. The methodology of the tests is contingent upon the established upper and lower critical bounds. Specifically, if the empirical values of the F and t statistics surpass the upper bound, the null hypothesis is rejected, indicating that the variables are cointegrated. Conversely, if the values fall below the lower bound, it suggests a lack of cointegration among the variables. In cases where the values reside between the critical bounds, the results of the test remain inconclusive. The estimated coefficient of the NARDL model will be spurious if variables are not cointegrated. This asymmetric cointegration technique under the nonlinear ARDL model has been proposed by (Shin et al., 2014 ). They have recommended applying the joint null hypothesis of level variables and evaluating the bound test's critical values proposed by (Pesaran et al., 2001 ). If the estimated value of F-statistics is obtained as more significant than the upper critical value, it confirms cointegration. If the F-value is closer to zero than the lower critical value, then there is no cointegration. If the F-value falls between the upper and lower critical values, then no conclusion can be drawn.

From the asymmetric Dynamic Multiplier Graphs above the following conclusion was made. 1-The continuous dark line tells how Addisababa market corrects due to a positive change in Asosa market, and the dashed black line shows the adjustment of the dependent variable lnAddisababa over the horizon to a negative shock in Asosa. 2-The dashed line is the asymmetric plot, and it shows the difference between the dynamic multiplier of positive and negative changes in the regressor. Asymmetric Dynamic Multipliers In order to explore whether the estimated coefficients are stable in the short and long term Das et al., ( 2023 ) the Cumulative Sum of Error Forecast (CUSUM) test is applied to verify stability (Pesaran et al., 2001 ). The results are shown in Fig. 11 with a 5% confidence band, and all the values in the sample are identified considering the Price transmission of the Different market for 2022. The stability of the parameters of NARDL model is examined using CUSUM and CUSUMSQ stability approach introduced by (Brown et al., 1975 ). If the blue lines cross upper or lower bounds, it implies that parameters are not stable in the model. Since the blue lines in both graphs are within lower and upper bounds, we can infer that parameters of the estimated model are stable. From the above fig, It indicates that it doesnot cross the determined bounds. It demonstrates the stability of the estimated coefficient because CUSUM is at a significance level of 5% in determining bounds.

Positive shocks are events that increase price of Groundnut in the surplus and deficit markets while negative shocks are events that decrease the price of groundnut in the deficit and surplus markets. Wald test was conducted to test the existence of asymmetry. Conclusion It is undeniable that comprehending the behavior of agricultural prices is crucial for the development of a viable Agricultural Development Plan and a sustainable food security policy. Throughout the years, numerous governments have endeavored to attain market efficiency by implementing diverse agricultural sector policies and programs. Their ultimate objective has been to ensure the availability of food from surplus to deficit areas, while also aiming to achieve positive welfare impacts from policy initiatives and address the disparities between deprived and affluent regions that arise from ecological variations and other factors. Despite such efforts, agricultural development policies in Ethiopia have concentrated much attention on increasing agricultural productivity while research on market price analysis has been relegated to the background. The purported ability of the market participants to influence the conduct of the market resulting in a full and faster transmission of cost increases to consumers than the contrary cost decreases makes it necessary to study the nature of market price linkages in Ethiopia. The study sought to acquire knowledge about the state of Groundnut markets in Ethiopia in the last decade. Using monthly Retail Groundnut prices data between 2000 to 2022 the study examined: the variation and trends within Groundnut prices in Six markets under study, price linkages among Surplus and deficit markets in Ethiopia between 2000 to 2022, whether price transmission between Surplus and deficit markets are symmetric or asymmetric and the extent to which Groundnut markets in Ethiopia are spatially integrated. A descriptive analysis of the data shows that the market with the highest average values for monthly Retail prices was Diredawa while the lowest value was Asosa. The variability in Groundnut market prices as determined by the coefficient of variation was on the average approximately 95.6 percent. The high fluctuations in mean Retail prices indicate that Groundnut prices were unstable. Also, the seasonal variation indicates that prices generally decline rapidly in the four months after the new crop harvest which comes in May for the all parts of the Ethiopia. A trend analysis in all the six markets shows that prices were lowest in May and highest in April. The annual trend also shows a general increase in price of groundnut over the years with a cyclical pattern in every six years that is 2017, 2018, 2019.2020, 2021 and 2012. All the price series showed econometric integration of the order I (1) meaning that similar stochastic processes generated these series. The test for cointegration using the Johansen Maximum Likelihood tests reveals that all the six market parings were cointegrated. The market pairs examined showed that their prices series do not diverge at equilibrium thus exhibiting spatial price linkage. The results complement earlier studies of market integration in the Ethiopian market, which potentially can be attributed to the non-interventionist role of the government, improvement in communication infrastructure and the different degrees of self- sufficiency that create arbitrage between the maize markets. The adjustment mechanism between the Groundnut markets after a shock was characterized by asymmetry where traders responded faster to shocks that squeezed their marketing margin than those that stretched them. Two out of the six markets pairs, lnAddisababa-lnJima and lnAddisababa-lnSawla, market exhibited positive asymmetry in price transmission even though the remaining markets show faster adjustment to price increases compared to price decreases, they are not statistically significant.

A NARDL Approach","fulltext":[{"header":"Introduction","content":"\u003cp\u003eIn countries where agriculture is the primary economic activity, particularly in the majority of sub-Saharan Africa, the agricultural sector and its related industries play a crucial role in fostering economic development and alleviating widespread poverty and food insecurity. In sub-Saharan African countries, among the crop types produced, groundnuts (\u003cem\u003eArachis hypogeas\u003c/em\u003e L.) are an essential crop, and the fifth most widely cultivated crop in sub-Saharan Africa, following maize, sorghum, millet, and cassava FAO (2010) holds significant importance within the agricultural landscape of Ethiopia. Although it ranks as the second-most essential oilseed crop after sesame (Amare et al., \u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e2017\u003c/span\u003e), its primary production is concentrated in the eastern regions of the country. The 2020 cropping season witnessed an estimated production of 205,069 tons from approximately 113,515 hectares, with a productivity of 1.8 tons per hectare (Debele et al., \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e2023\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eStrong connections to markets are being increasingly acknowledged for their role in poverty alleviation, food security, and rural community advancement within the agricultural sector (Livingston et al., \u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e2011\u003c/span\u003e). Organizations and development experts prioritize market interaction as a means to enhance agricultural output, foster economic growth, and diminish poverty and hunger among rural producers. This emphasis on market connections impacts food security, income levels, and overall productivity, creating a positive feedback loop that motivates small producers to invest in their businesses, enhance output quality, and diversify product lines (Livingston et al., \u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e2011\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eAgricultural markets and access to market information are crucial for the effective engagement of smallholder farmers in agricultural markets (Magesa et al., \u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e2014\u003c/span\u003e). Smallholder farmers, particularly those involved in groundnut production, encounter challenges in accessing vital market information, such as commodity pricing in local markets (Ross and de Klerk, \u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e2012\u003c/span\u003e). This limitation significantly impacts the farmers\u0026rsquo; ability to make informed and profitable trading decisions, inhibiting their capacity to exploit seasonal and spatial arbitrage opportunities. The absence of accurate market price information often compels smallholder farmers to accept the prices offered by buyers, thus compromising their marketing decisions.\u003c/p\u003e\u003cp\u003eIn integrated markets, food commodities flow from surplus to deficit areas. Deficit areas, typically associated with high prices, create an incentive for traders to transport food from surplus to deficit areas (Abay et al., \u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e2023\u003c/span\u003e). Rational traders enter the market and capitalize on these arbitrage opportunities by increasing demand for the commodity in surplus areas while simultaneously boosting the supply of the commodity in deficit areas. This process continues until prices in both markets reach an equilibrium level, rendering trade unprofitable (Lupiya, \u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e2018\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eThis study analyzes the process characterized as asymmetric, where the transmission of price changes varies depending on whether prices are rising or falling. It is frequently claimed that traders leverage their market power to implement pricing strategies that facilitate a swift and comprehensive pass-through of cost increases, while the transmission of cost reductions occurs more slowly and is less complete (Kinnucan and Forker, \u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e1987\u003c/span\u003e).\u003c/p\u003e\u003cdiv id=\"Sec2\" class=\"Section2\"\u003e\u003ch2\u003e1.1. Asymmetry in Price Transmission\u003c/h2\u003e\u003cp\u003eWhen the response of market at one level responds differently to a decrease and increase in price at a different level, then asymmetry exist. Asymmetry could exist in the magnitude or the speed of adjustment or both. In the former, short-run elasticities of price transmission differ according to the sign of the initial change while in the latter, long-run elasticity differ (VonCramon-Taubadel, \u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e1998\u003c/span\u003e). Asymmetry can also be classified as positive (when one price responds fully or quickly to an increase in another price as to a decrease, thus price movement that squeezes the margin is transmitted more rapidly and/or completely as the movement that stretches the margin). Otherwise, negative (when one price responds fully or quickly to a decrease in another price than to an increase; thus rapid and/or complete transmission to price movements that stretch the margin). This determines the direction of welfare transfer (Meyer and von Cramon-Taubadel, \u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e2004\u003c/span\u003e). Asymmetry can also be considered to be vertical if determined along the food supply chain (e.g. from farm level to wholesale level) or spatial when determined between two geographically separated markets.\u003c/p\u003e\u003cp\u003eAsymmetric price transmission has long been associated with agricultural prices with the idea starting from Tweeten and Quance (\u003cspan citationid=\"CR29\" class=\"CitationRef\"\u003e1969\u003c/span\u003e) that used dummy variable to split input prices into increasing and decreasing input prices. Following this, studies such as Acharjee et al., (\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e2023\u003c/span\u003e) suggest that the price transmission pattern is symmetric in the short run but could be a mixture of symmetric and asymmetric in the long run. This asymmetric price behavior indicates that changes in retail prices do not get reflected fully at both farmgate and wholesale prices, and the transmitted prices may vary according to the retail prices based on their rising or falling pattern.\u003c/p\u003e\u003cp\u003eThese studies, however, predated the development of cointegration and did not consider the problems related to nonstationary series (Hassouneh et al., \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e2012\u003c/span\u003e). Granger and Lee (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e1989\u003c/span\u003e) therefore incorporated the variable splitting technique into the error correction representation to correct for the problem of nonstationarity. Since then, variants of this approach have been used extensively in applied work (von Cramon-Taubadel and Loy, \u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e1996\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eOther studies Abdulai (\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2000\u003c/span\u003e); Enders and Granger (\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e1998\u003c/span\u003e) and Enders and Siklos (\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e2001\u003c/span\u003e) also have captured asymmetry using threshold models, where price movements above or below certain thresholds trigger different response. A number of potential causes but limited have been attributed to asymmetries in price transmission. Among studies addressing this issue include (Meyer and von Cramon-Taubadel, \u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e2004\u003c/span\u003e, \u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e2004\u003c/span\u003e,Frey and Manera, \u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e2007\u003c/span\u003e and Abdulai, \u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2000\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eSome of the potential causes of asymmetry discussed in literature include market power. Market power refers to the ability of an enterprise or a group of enterprises to raise and maintain price above or below a competitive level (Amonde et al., \u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e2009\u003c/span\u003e). In non-competitive market structure where there is considerable degree of market power, market agents react quickly and/ or more completely to shocks that squeeze their marketing margin than to corresponding shocks that stretches them, resulting in positive asymmetry. Positive asymmetry is, however, not the only resulting effect of market power. Ward (\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e1982\u003c/span\u003e) indicates that oligopolists can be reluctant to increase market prices for the risk of losing market share. The positive asymmetry appears to be reasonable in pure monopoly while both positive and negative asymmetries are conceivable in the more common oligopolistic context (Meyer and von Cramon- Taubadel, 2004).\u003c/p\u003e\u003cp\u003eFrey and Manera (\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e2005\u003c/span\u003e) also present a comparable argument regarding tacit collusion in oligopolistic markets. In this scenario, when wholesale prices rise, firms promptly raise their selling prices as a signal to their competitors, indicating their compliance with the tacit agreement. Conversely, when wholesale prices decrease, firms are cautious in adjusting their prices, as doing so may risk signaling a reduction in their profit margins and deviating from the agreement.\u003c/p\u003e\u003cp\u003eAdjustment/menu costs are another factor that contributes to the presence of asymmetry. These costs are incurred by firms when they decide to alter the quantities and/or prices of their inputs and/or outputs. When these costs are specifically related to price adjustments, they are referred to as menu costs (Meyer and von Cramon-Taubadel, \u003cspan citationid=\"CR23\" class=\"CitationRef\"\u003e2004\u003c/span\u003e). Menu costs encompass various expenses such as the cost of modifying nominal prices, printing catalogues, dealing with inflation-related costs, and disseminating information regarding price changes. It is worth noting that these costs may exhibit asymmetry in relation to price increases and decreases.\u003c/p\u003e\u003c/div\u003e"},{"header":"Methodology","content":"\u003cdiv id=\"Sec4\" class=\"Section2\"\u003e\u003ch2\u003e2.1. Study area and data sources\u003c/h2\u003e\u003cp\u003eThe Study was primarily examined four specific areas in Ethiopia: Oromia (Jima), Benishangul-Gumuz (Asosa), Amhara (Este), Central Ethiopia Regional State (Sawla), Diredawa, and Addis Ababa. These regions are part of the Twelve Regions of Ethiopia, with Addis Ababa serving as the nation's capital and Diredawa as a municipality. While Addis Ababa and Diredawa are considered consumption hubs, the four regions mentioned are recognized as significant groundnut production zones. Among them, Oromia Region stands as the largest groundnut producer, followed by Benishangul-Gumuz, according to the (Sendekie, \u003cspan citationid=\"CR27\" class=\"CitationRef\"\u003e2023\u003c/span\u003e).\u003c/p\u003e\u003cp\u003eThe markets that are studied in the Oromia region was Jima, while in the Amhara region was Este, BenishengulGumuz region was Asosa and SNNPR regions, Sawla markets was studied.

The criterion for selecting these markets is based on net market positions (surplus and deficit), geographical distribution, data availability and the volume of trade or the importance of the market to the national Groundnut trade flow.\u003c/p\u003e\u003c/div\u003e\u003cdiv id=\"Sec5\" class=\"Section2\"\u003e\u003ch2\u003e2.2.

Econometric Model\u003c/h2\u003e\u003cp\u003eThe examination of time series data involves several critical procedures, one of which is the verification of the stationarity of research variables, ensuring that none exhibit integration beyond the second order. Consequently, it is essential to analyze the unit root properties of the variables utilized in the study. The presence of multiple orders of integration within a variable can lead to misleading results. To assess the order of integration of the variables, we employed the Augmented Dickey\u0026ndash;Fuller (ADF) and Phillips\u0026ndash;Perron (PP) unit root tests prior to the application of the time series econometric model. Additionally, before investigating causality, it is crucial to evaluate the cointegrating relationships among the variables. We implemented the Bounds cointegration test to determine whether any cointegration exists between the variables.\u003c/p\u003e\u003cp\u003e\u003cb\u003eThe NARDL Model\u003c/b\u003e\u003c/p\u003e\u003cp\u003eThe study employed the NARDL approach to examine the asymmetric price transmission between markets experiencing surplus and those in deficit, specifically focusing on the relationship concerning groundnut prices.\u003c/p\u003e\u003cp\u003eThe Non-linear ARDL model recently developed by Shin et al., (\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e2014\u003c/span\u003e) uses positive and negative partial sum decompositions allowing detecting the asymmetric effects in the long and the short-term. Compared to the classical cointegration models, NARDL models present some other advantages. Firstly, they perform better for determining cointegration relations in small samples (Romilly et al., \u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e2001\u003c/span\u003e). Secondly, they can be applied irrespective of whether the regressors are stationary at level or at the first difference (i.e. I(0) or I(1)). They cannot be applied however if the regressors are I(2).

This variability can be attributed to a range of factors, including natural influences like weather fluctuations, as well as economic factors such as transportation expenses, market participants, and alterations in marketstructure. According to Table \u003cspan class=\"InternalRef\"\u003e1\u003c/span\u003e, Diredawa and Addisababa exhibited the highest nominal mean prices at 29.89 and 28.69 ETB per Kg respectively, whereas Asosa and Este showed the lowest mean prices at 13.49 and 22.83 ETB respectively. The high prices in both Diredawa and Addisababa were as a result of urban demand of groundnuts that outpaced supply (Bayata and Nega, \u003cspan class=\"CitationRef\"\u003e2020\u003c/span\u003e). The low prices recorded in Asosa, Sawla and Este can be attributed to the fact that the markets are located in the main groundnut growing regions across the country.\u003c/p\u003e\n\u003cp\u003eThe variations in nominal groundnut prices in regions with both shortages and excesses are depicted in Figures (1) and (2) below. Prices in Diredawa and Addisababa were notably higher compared to those in the areas where groundnuts are produced, leading to a more distinct graphical representation. Overall, a consistent price pattern has been observed in all six markets, indicating that groundnut prices have moved in the same direction throughout the years.

Since all variables were stationary after first difference, meaning that they were integrated of order1, that is to say I (1). This is one of the conditions for testing co-integration that depicts the existence of a long-run relationship among the six groundnuts markets. Similarly, Kwiatkowski Philips Schmidt Shin (KPSS) found the same results with ADF tests. That is since the value of KPSS test statistics for the first difference of all market price series is smaller than the critical value at the 0.01 level of significance. We fail to reject the null hypotheses of stationarity at the 1% level of significance. This implies that the first differenced series of the all market are stationary.\u003c/p\u003e\n \u003cp\u003e\u003cstrong\u003eAssymetric cointegration test for Diredawa- Este market\u003c/strong\u003e\u003c/p\u003e\n \u003cp\u003e\u003cstrong\u003eF bound test\u003c/strong\u003e\u003c/p\u003e\n \u003cp\u003eUpon verifying the order of integration, the next step involves examining the cointegrating properties of the variables. We employed the Bounds cointegration tests, utilizing both F statistics and t statistics, to determine the presence of cointegration among the variables. The methodology of the tests is contingent upon the established upper and lower critical bounds. Specifically, if the empirical values of the F and t statistics surpass the upper bound, the null hypothesis is rejected, indicating that the variables are cointegrated. Conversely, if the values fall below the lower bound, it suggests a lack of cointegration among the variables. In cases where the values reside between the critical bounds, the results of the test remain inconclusive.\u003c/p\u003e\n \u003cp\u003eThe estimated coefficient of the NARDL model will be spurious if variables are not cointegrated. This asymmetric cointegration technique under the nonlinear ARDL model has been proposed by (Shin et al., \u003cspan class=\"CitationRef\"\u003e2014\u003c/span\u003e). They have recommended applying the joint null hypothesis of level variables and evaluating the bound test\u0026apos;s critical values proposed by (Pesaran et al., \u003cspan class=\"CitationRef\"\u003e2001\u003c/span\u003e). If the estimated value of F-statistics is obtained as more significant than the upper critical value, it confirms cointegration.

Throughout the years, numerous governments have endeavored to attain market efficiency by implementing diverse agricultural sector policies and programs. Their ultimate objective has been to ensure the availability of food from surplus to deficit areas, while also aiming to achieve positive welfare impacts from policy initiatives and address the disparities between deprived and affluent regions that arise from ecological variations and other factors. Despite such efforts, agricultural development policies in Ethiopia have concentrated much attention on increasing agricultural productivity while research on market price analysis has been relegated to the background. The purported ability of the market participants to influence the conduct of the market resulting in a full and faster transmission of cost increases to consumers than the contrary cost decreases makes it necessary to study the nature of market price linkages in Ethiopia.\u003c/p\u003e\u003cp\u003eThe study sought to acquire knowledge about the state of Groundnut markets in Ethiopia in the last decade. Using monthly Retail Groundnut prices data between 2000 to 2022 the study examined: the variation and trends within Groundnut prices in Six markets under study, price linkages among Surplus and deficit markets in Ethiopia between 2000 to 2022, whether price transmission between Surplus and deficit markets are symmetric or asymmetric and the extent to which Groundnut markets in Ethiopia are spatially integrated.\u003c/p\u003e\u003cp\u003eA descriptive analysis of the data shows that the market with the highest average values for monthly Retail prices was Diredawa while the lowest value was Asosa. The variability in Groundnut market prices as determined by the coefficient of variation was on the average approximately 95.6 percent. The high fluctuations in mean Retail prices indicate that Groundnut prices were unstable. Also, the seasonal variation indicates that prices generally decline rapidly in the four months after the new crop harvest which comes in May for the all parts of the Ethiopia. A trend analysis in all the six markets shows that prices were lowest in May and highest in April. The annual trend also shows a general increase in price of groundnut over the years with a cyclical pattern in every six years that is 2017, 2018, 2019.2020, 2021 and 2012.\u003c/p\u003e\u003cp\u003eAll the price series showed econometric integration of the order I (1) meaning that similar stochastic processes generated these series. The test for cointegration using the Johansen Maximum Likelihood tests reveals that all the six market parings were cointegrated. The market pairs examined showed that their prices series do not diverge at equilibrium thus exhibiting spatial price linkage. The results complement earlier studies of market integration in the Ethiopian market, which potentially can be attributed to the non-interventionist role of the government, improvement in communication infrastructure and the different degrees of self- sufficiency that create arbitrage between the maize markets.\u003c/p\u003e\u003cp\u003eThe adjustment mechanism between the Groundnut markets after a shock was characterized by asymmetry where traders responded faster to shocks that squeezed their marketing margin than those that stretched them. Two out of the six markets pairs, lnAddisababa-lnJima and lnAddisababa-lnSawla, market exhibited positive asymmetry in price transmission even though the remaining markets show faster adjustment to price increases compared to price decreases, they are not statistically significant.\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eAcknowledgement\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe authors would like to express sincere gratitude to the Ethiopian statistical Service for providing the secondary Data access that supported this study.

This research aims to analyze the spatial price transmission and market integration of significant groundnut markets in Ethiopia, utilizing monthly retail price data from September 2000 to August 2022. A combination of descriptive and econometric methods was employed for the analysis. The descriptive statistics indicated that consumption areas exhibited the highest nominal mean prices, with Dire Dawa and Addis Ababa reporting ETB29.89 and ETB28.69 per kilogram, respectively, whereas the producing regions showed the lowest average prices for groundnuts. The Augmented-Dickey Fuller test was used to test for the stationarity of individual price series and was confirmed by the KPSS test. All the price series data that were used tested for Unit Root. They were found to be non-stationary at levels but stationary after first difference at 1%, 5% and 10% significant levels. Johansen Co-integration test was used to test for long- run relationships between the market pair.It was found that all six market pairs were cointegrated at 5% level of significance. The Non-linear Auto Regressive Distributed Lag Model shows asymmetric price transmission in two market pairs, indicating quicker adjustments to price increases than decreases. The study implys the influence of geographical differences, distance, and production volume on market integration. This study provides significant contributions to the formulation of agricultural marketing policies and deepens our comprehension of market dynamics in Ethiopia.\u003c/em\u003e\u003c/p\u003e","manuscriptTitle":"Asymmetric price Transmission of the Groundnut market in Ethiopia.
