Customs data reveal heterogeneity and granularity of relationships among buyers and sellers. A key insight is how more exports to a destination break down into more firms selling there and more buyers per exporter. We develop a quantitative general equilibrium model of firm-to-firm matching...

Climate policies vary widely across countries, with some countries imposing stringent emissions policies and others doing very little. When climate policies vary across countries, energy-intensive industries have an incentive to relocate to places with few or no emissions restrictions, an effect...

An endogenous growth model with financial intermediation is used to show how public deposit insurance and weak prudential regulation can lead to banking crises and permanent declines in economic growth. The impact of regulatory forbearance on investment, saving and asset price dynamics under...

We construct an index of financial development for 23 Asian economies based on subindices of access, depth, and efficiency of financial institutions and markets and find evidence that economies with weaker financial systems are catching up to the Asian benchmark economies, namely Hong Kong,...

This paper compares the sources of income inequality in Japan and the United States. We exploit two longitudinal household surveys to decompose the income inequality in both countries. For Japan, we use Keio Household Panel Survey data and the five latest waves (2009-2013). For the United...

We derive the optimal unilateral policy in a general equilibrium model of trade and climate change where one region of the world imposes a climate policy and the rest of the world does not. A climate policy in one region shifts activities—extraction, production, and consumption—in the other...

Japan's savings are among the highest in the world, and these high rates have played a valuable role throughout the post-war period. However, over the next several decades, Japan's population will be ageing rapidly. Will this lower Japanese savings rates? Using up-to-date financial and...

We develop a parsimonious model of innovating firms rich enough to confront firm-level evidence. It captures the dynamic behavior of individual heterogeneous firms, describes the evolution of an industry with simultaneous entry and exit, and delivers a general equilibrium model of technological...

The ratio of global trade to GDP declined by nearly 30 percent during the global recession of 2008-2009. This large drop in international trade has generated significant attention and concern. Did the decline simply reflect the severity of the recession for traded goods industries? Or...
