We compare three theoretical explanations for the positive empirical relationship between importer income per capita and traded goods prices. A first explanation is that consumers with higher incomes demand higher quality goods with higher prices. A second explanation is that wealthier people...

This paper investigates the heterogeneous response of exporters to real exchange rate fluctuations due to product quality. We model theoretically the effects of real exchange rate changes on the optimal price and quantity responses of firms that export multiple products with heterogeneous levels...

We introduce firm and worker heterogeneity into a model of innovation-driven endogenous growth. Individuals who differ in ability sort into either a research sector or a manufacturing sector that produces differentiated goods. Each research project generates a new variety of the differentiated...

This Paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...

This paper estimates a structural model of economic geography using cross-country data on per capita income, bilateral trade, and the relative price of manufacturing goods. More than 70% of the variation in per capita income can be explained by the geography of access to markets and to sources...

This paper tackles the issue of the optimality of agglomeration in a two-region economy with skilled/mobile and unskilled/immobile workers. The market leads to the optimal outcome when transport costs are high or low. However, for intermediate values, it yields agglomeration whereas dispersion...

This paper tests whether trade in new goods is partially responsible for the pro-trade effects of the euro and provides a measure of the size of the effect. It works with a very large data set (about 16 million observations) covering twenty countries at the most disaggregated level of trade data...

This paper investigates the possibility of endogenous fluctuations in the international distribution of economic activities in the presence of increasing returns, monopolistic competition, trade and convex adjustment costs without allowing for any local productive externalities. Using a...

This Paper presents firm level evidence on the dynamics of non-manual wage premia and employment shares in Italian manufacturing during the nineties. We find that the relative stability of aggregate wage premia and employment shares hides offsetting disaggregate forces. First, while technical...
