Schumpeter's concept of creative destruction as the engine of capitalist development is well-known. However, that the destructive part of creative destruction is a social cost and therefore biases our estimate of the impact of the innovation on NNP and on welfare is hardly acknowledged, with the...

We develop a dynamic multi-country general equilibrium model to investigate forces acting on the global economy during the Great Recession and ensuing recovery. Our multi-sector framework accounts completely for countries' trade, investment, production, and GDPs in terms of different sets of...

We study the output costs of 40 systemic banking crises since 1980. Most, but not all, crises in our sample coincide with a sharp contraction in output from which it took several years to recover. Our main findings are as follows. First, the current financial crisis is unlike any others in terms...

Cyclical fluctuations in nominal variables--aggregate price levels and nominal interest rates--are documented to be substantially more synchronized across countries than cyclical fluctuations in real output. A transparent mechanism that can account for this striking feature of the nominal...

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...

A large body of cross-country empirical evidence identifies monetary policy and trade integration as key determinants of business cycle co-movement. Partially consistent with this, many argue that the re-emergence of the gold standard allowed for the global transmission of a deflationary shock...

We develop a model of investment with financial constraints and use it to investigate the relation between investment and Tobin's q. A firm is financed partly by insiders, who control its assets, and partly by outside investors. When their wealth is scarce, insiders earn a rate of return higher...
