Based on a quantitative, heterogeneous agent general equilibrium model, we compute the optimal tax rates for labor and capital incomes for the Korean economy. According to our model, a more progressive income tax schedule along with a higher capital tax rate can increase average welfare by as...

We develop a quantitative heterogeneous-agents general equilibrium model that reproduces the income inequalities of 32 countries in the Organization for Economic Co-operation and Development. Using this model, we compute the optimal income tax rate for each country under the equal-weight...

Standard heterogeneous agent macro models that highlight idiosyncratic productivity shocks do not generate the near zero cross-sectional correlation between hours and wages found in the data. We ask whether matching this moment matters for business cycle properties of these models. To do this we...

This paper investigates the factors explaining exchange market pressures (EMP) and the hoarding and use of international reserves (IR) by emerging markets during the 2000s, as the Great Moderation turned to the 2008-9 global crisis and great recession. According to our results, both financial...

International financial integration has greatly increased the scope for changes in a country's net foreign asset position through the valuation channel of external adjustment, namely capital gains and losses on the country's external assets and liabilities. We examine this valuation channel...

Three current account imbalances - one very large deficit (the United States) and two surpluses (Japan and the Euro area) - are subjected to a minimalist structural interpretation. Though simple, this interpretation enables us to assess how much of each of the imbalances require a real exchange...

The sizable hoarding of international reserves by several East Asian countries has been frequently attributed to a modern version of monetary mercantilism hoarding international reserves in order to improve competitiveness. From a long-run perspective, manufacturing exporters in East Asia...
