This paper explores patterns of quality differentiation and specialization relying on model-level panel data of retail sales and prices of refrigerators across 23 countries in the European Union. Unlike customs data aggregated at the product category, typically used in the literature,...

Observed Engel curves are non-monotonic, hence consumption goods may be regarded as luxuries only for ranges of consumer income. This paper rationalises this evidence by postulating that quality of consumption governs the distribution of spending across goods. We argue that quality upgrading as...

We show that the introduction in a power utility function of a confidence index to sig- nal the state of the world allows for an otherwise standard asset pricing model to match the observed consumption growth volatility and excess returns with a reasonable level of relative risk aversion. Our...

The literature on North-South trade has explored conditions under which international trade might be a factor magnifying income disparities between the advanced North and the backward South. Little attention has yet been placed on the effect of trade on countries that do not display substantial...

An omitted variable in the household's preferences specification may lead to overestimate the volatility of consumption, or alternatively to overvalue the risk aversion coefficient required to match the equity premium. This paper proposes to augment the utility function by adding a nontradable...

We propose a theory of trade in which comparative advantages reveal themselves gradually over the path of development. Following the Ricardian tradition, countries specialise and export the set of goods they are able to produce at relatively lower cost given their exogenous initial endowments....

Recent macro-finance contributions explain a great deal of unconditional asset pricing by introducing persistent consumption risks and rare disasters. Only the volatility puzzles remain unresolved among the longer-established issues in this literature. Motivated by empirical finance...
