We incorporate trade imbalances into a quantitative model of bilateral trade in manufactures, dividing the world into forty countries. Fitting the model to 2004 data on GDP and bilateral trade we calculate how relative wages, real wages, and welfare would differ in a counterfactual world with...

We use a forty-two country model of production and trade to assess the implications of eliminating current account imbalances for relative wages, relative GDP's, real wages, and real absorption. How much relative GDP's need to change depends on flexibility of two forms: factor mobility and the...

We use Japanese prefectural wage and land price data to estimate the magnitude of agglomeration effects in manufacturing and finance. We also examine the range of agglomeration effects by estimating the extent to which they diminish with distance, using a specification that encompasses the polar...

A model of the domestic financial intermediation of foreign capital inflows based on agency costs is developed for studying financial crises in emerging markets. In equilibrium for the model economy, the banking system becomes progressively more fragile under imperfect prudential regulation and...

Compared to the U.S. national accounts, the Japanese accounts understate consumption and government spending, and therefore overstate the national saving rate. Recently, Hayashi has recalculated Japan's national saving according to the American Department of Commerce definition and found that...

We project the impact of demographic change on Japanese capital flows by simulating the impact of population aging on Japanese saving and investment rates. As aging depresses saving rates, in our baseline projections, we show that by 2015, foreign capital inflows will comprise about 15 percent...

Japan's deteriorating fiscal situation has attracted international attention. I assess what current Japanese government policies mean for the future of public debt and the economy in general, given the inevitable aging of the population. I review how Japan got into this current fiscal mess, and...

We explore the determinants of research specialization across countries and its consequences for relative wages. Using a dynamic Ricardian model we examine the effects of faster international technology diffusion and lower trade barriers on the incentive to innovate. In the absence of any...

Free trade is not optimal for a small country that faces uncertain terms of trade if some factors are immobile - ex post, and markets for contingent claims are incomplete. The government can improve social welfare by using commercial policy that serves as a partial substitute for missing...

If contracts are costlessly enforcible then insolvency is the only reason for nonrepayment of loans. While some models have examined the borrower's incentive to repay, it has typically been assumed that the penalty suffered by a debtor in default is imposed automatically and without cost to the...
