R&D-based models of endogenous technical progress rest on a premise that technical progress is driven by profit-seeking entrepreneurs. This literature led to a dominant view that endogenous technical advance is not consistent with perfect competition with constant returns to scale. Departing...

We estimate determinants of dynamic correlations of output comovement of OECD countries between 1990 and 2008. We show that trade intensity, degree of financial integration and specialization pattern have significantly different effects on comovements at different frequencies. This can bias the...

Although the one-factor Ricardian trade model with external economies of scale plays a significant role for the understanding of important trade issues under increasing returns, it lacks a compelling graphical representation. We propose a convincing graphical exposition that uses both the PPF...

Although the home-market effect has become one of the most important concepts in both trade theory and the new economic geography, it lacks a compelling graphical representation. The purpose of this note is to offer such a representation. We will decompose the homemarket effect into two steps: a...

In this paper, we derive asymptotic theorems for the Petrin (2002) extension of the Berry, Levinsohn, and Pakes (BLP, 1995) framework to estimate demand-supply models with micro moments. The micro moments contain the information relating the consumer demographics to the characteristics of the...
