This paper combines default, settlement, and repayment history into a unified, dynamic borrowing model of sovereign debt. The model addresses two questions: 1) how the level of debt and the income profile affect the length of time a country in default is excluded from the international credit...

This paper studies co-movement in economic aggregates at the national and international level. At the national level, consumption, investment and hours worked display positive co-movement across the business cycle. Technology shocks, which directly affect the real wage rate, can drive...

Conventional two-country RBC models interpret countercyclical net exports as reflecting, in large part, the dynamics of capital. I show that, quantitatively, theoretical economies rely on counterfactual terms of trade effects: trade fluctuations, on the contrary, are driven primarily by...

This paper examines the business cycle properties of capital goods trade in open economies. Capital good imports and exports are twice as volatile as investment. Equipment trade is asymmetric in that small countries are net importers. Countercyclical trade balances are associated with...

Current account crises in emerging markets are characterized by large increases in interest rates, big drops in output, and large real currency depreciations. Current models of crisis with financial frictions do not generate very large movements in these variables. Recent work has shown that the...

This paper examines the importance of productivity shocks in accounting for salient features of U.S. economic developments during the second half of the 1990s, including the surge in investment spending, the substantial deterioration of the trade balance, and the modest decline in inflation. We...

Standard international real business cycle models are generally unable to replicate the observed comovements of all the main aggregate variables: in particular, they generate low or negative international comovements in output, investment, and labour. I simulated a two-country, two-sector...

I construct a heterogeneous agents economy that mimics the time-series behavior of the US earnings distribution from 1963 to 2003. Agents face aggregate and idiosyncratic shocks and accumulate real and financial assets. I estimate the shocks driving the model using data on income inequality, on...
