We show analytically that in a rational expectations present value model, an asset price manifests near random walk behavior if fundamentals are I(1) and the factor for discounting future fundamentals is near one. We argue that this result helps explain the well known puzzle that fundamental...

We study the macroeconomic consequences of tariffs. We estimate impulse response functions from local projections using a panel of annual data that spans 151 countries over 1963-2014. We find that tariff increases lead, in the medium term, to economically and statistically significant declines...

We document a new international stylized fact describing the relationship between real exchange rates and external asset holdings. Economists have long argued that the real exchange rate is associated with the net international investment position, appreciating as external wealth increases. This...

I use microeconomic estimates of the effect of health on individual outcomes to construct macroeconomic estimates of the proximate effect of health on GDP per capita. I employ avariety of methods to construct estimates of the return to health, which I combine with cross-country and historical...

This paper explores the effect of news shocks on the current account and other macroeconomic variables using worldwide giant oil discoveries as a directly observable measure of news shocks about future output-the delay between a discovery and production is on average 4 to 6 years. We first...

This paper offers an explanation for the persistence observed in real exchange rate movements. The model combines pricing to market behavior with sticky prices generated by staggered contracts. A translog preference structure is sued to enhance both features. The paper finds that openness limits...

The purchasing power parity puzzle relates to the adjustment of real exchange rates. Real exchange rates are extremely volatile, suggesting that temporary shocks emanate from the monetary sector. But the half-life of real exchange rate deviations is extremely large -- 2.5 to 5 years. This...

A sticky-price model is used to motivate a structural VAR analysis of the current account and the real exchange rate for seven major industrialized countries (the US, Canada, the UK, Japan, Germany, France and Italy). The analysis is distinguished from previous work in that it adopts minimal...

The presence of purchasing power parity is often attributed to the exploitation of arbitrage opportunities in goods markets. We examine this presumption for a 1960-1996 monthly panel of bilateral exchange rates and trade for the G7 countries. The data exhibit strong mean reversion. However,...
