This study tests the relevance of Duesenberry’s relative income hypothesis in Ethiopia by examining its demonstration and ratchet effects on average propensity to consume (APC) using quarterly data from 1999/2000Q1 to 2018/2019Q4 and estimating two relative-income specifications with an Autoregressive Distributed Lag (ARDL) model. The authors report a backward-J-shaped demonstration effect, where increases in relative income produce a steeper reduction in APC among lower-income households, and they also find evidence consistent with a ratchet effect whereby past consumption habits influence current consumption decisions. They state that the coexistence of demonstration and ratchet effects corresponds to a stable long-run APC that helps explain a consumption “puzzle,” but the work is presented as a preprint and not peer reviewed by a journal. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract Although it was mysteriously neglected and displaced by the mainstream consumption theories, the Duesenberry’s relative income hypothesis seems quite relevant to the modern societies where individuals are increasingly obsessed with their social status. Accordingly, this study aims to investigate the relevance of Duesenberry’s demonstration and ratchet effects in Ethiopia using a quarterly data from 1999/2000Q1-2018/19Q4. To this end, two specifications of relative income hypothesis are estimated using Autoregressive Distributed Lag (ARDL) regression model. The results confirm a backward-J shaped demonstration effect. This implies that an increase in relative income induces a steeper reduction in Average Propensity to consume (APC) at lower income groups (the demonstration effect is stronger for lower income households). The results also support the ratchet effect, indicating the importance of past consumption habits for current consumption decisions. In resolving the consumption puzzle, the presence of demonstration and ratchet effects reflects a stable APC in the long-run. Hence, consumption-related policies should be carefully designed as polices aimed at boosting aggregate demand can motivate low income households to gallop into wasteful competition so as to ‘keep up with the Joneses’—the relative riches.
