Effective arrangements for micro and macroprudential policies to further overall financial stability are strongly desirable for all countries, emerging or advanced. Both policies complement each other, but there can also be potential areas of overlap and conflict, which can complicate this...

The key ideas for adding financial market frictions in general equilibrium models are not new in macroeconomics. However, it is only with the recent crisis that the profession has fully recognized the importance of financial markets for business cycle fluctuations. In this article I review some...

We find the optimal target values for fiscal rules and measure their aggregate effects using a model of sovereign default. We calibrate the model to an economy that pays a significant sovereign default premium when the government is not constrained by fiscal rules. For different levels of the...

We measure the effects of debt dilution on sovereign default risk and show how these effects can be mitigated with debt contracts promising borrowing-contingent payments. First, we calibrate a baseline model à la Eaton and Gersovitz (1981) to match features of the data. In this model, bonds'...

Two striking facts about international capital flows in emerging economies motivate this paper: (1) Governments hold large amounts of international reserves, for which they obtain a return lower than their borrowing cost. (2) Purchases of domestic assets by nonresidents and purchases of foreign...

In recent years a number of countries have undertaken far-reaching reforms of their financial sectors. Generally speaking, financial sector reforms aim at achieving greater flexibility of interest rates, an enhanced role for market forces in credit allocation, increased independence for the...

This paper considers whether short-period deterministic cycles can exist in a class of stationary overlapping generations models with long- (but finite-) lived agents. It shows that if agents discount the future positively, then as life spans get large, nonmonetary cycles will disappear....

This paper reviews the "Austrian" theory of the business cycle first proposed by Friedrich Hayek in the 1920s. His theory claimed that credit creation by monetary authorities would push investment beyond society's long-term willingness to save, creating a mismatch between supply and demand that...
