We estimate the variety gains of trade in Estonia, Latvia and Lithuania following the fall of the iron curtain more than a quarter of a century ago. We apply the methodology of Feenstra (1994); Broda and Weinstein (2006); Ardelean and Lugovskyy (2010) and Soderbery (2015) to domestic and...

We analyze investment decisions when information is costly, with and without delegation to an agent. We use a rational-inattention model and compare it with a canonical signal-extraction model. We identify three "investment conditions". In "sour" conditions, no information is acquired and no...

Owing to past structural reforms, Costa Rica has enjoyed robust GDP growth and productivity levels are gradually converging towards the OECD average. However, large GDP per capita and productivity gaps persist. In addition, not everyone has benefited from this growth. Inequality has increased...

We examine the dynamics of ideas production and knowledge-productivity relationship in a panel of 19 OECD countries. A new data set of triadic patents is used. We rigorously address the issues of cross-country heterogeneity and endogeneity. Domestic and foreign ideas stocks exert positive but...

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...

We examine the dynamics of knowledge production for a panel of 19 OECD countries. A new and unique data set is used to proxy the domestic flows of “new-to-the-world” knowledge and ideas. We rigorously address the cross-country heterogeneity in the production of knowledge and the endogeneous...

Innovation depends on exporting and, in particular, on scale and competition in export markets. We develop a theory featuring (1) quality-segmented markets, (2) step-by-step innovation that moves firms forward along the quality ladder, and (3) escape-the-competition motives for innovation. We...
