The international macroeconomics literature has had a hard time capturing the joint comovement of quantities and asset prises across countries. We introduce recursive preferences in an endogenous growth model of innovation and technology adoption through trade in varieties and provide an...

change leads simultaneously to both higher growth and more trade.

GDP per hour (rather than GDP per capita) better measures labor productivity.

Countries with weaker economic fundamentals experienced higher currency volatility and capital flows.

Fear of demand-driven deflation calls for expansionary economic policies.

Countries that trade more with each other tend to have more correlated business cycles. Yet, traditional international business cycle models predict a much weaker link between trade and business cycle comovement. We propose that fluctuations in the number of varieties embedded in trade flows may...

In this paper, we establish the importance of experience in international trade for reducing trade costs and facilitating bilateral trade. Within an augmented gravity framework, we find that an additional year of experience at the country-pair level reduces trade costs by 2.0% and increases...

I develop a structural general equilibrium model and estimate it for New Zealand using Bayesian techniques. The estimated model considers a monetary policy regime where the central bank targets overall inflation but is also concerned about output, exchange rate movements, and interest rate...

We develop a model in which innovations in an economy's growth potential are an important driving force of the business cycle. The frame- work shares the emphasis of the recent “new shock” literature on revisions of beliefs about the future as a source of fluctuations, but differs by tieing...

I develop a multicountry-model in which economic growth is driven mainly by domestic innovation and the adoption of foreign technologies embodied in traded intermediate goods. Fitting the model to data on innovation, output per capita, and trade in varieties for the period 1996-2007, I estimate...
