We model the motives for residents of a country to hold foreign assets, including the precautionary motive that has been omitted from much previous literature as intractable. Our model captures many of the principal insights from the existing specialized literature on the precautionary motive,...

We examine the determinants of external crises, focusing on the role of foreign liabilities and their composition. Using a variety of statistical tools and comprehensive data spanning 1970-2011, we find that the ratio of net foreign liabilities to GDP is a significant crisis predictor. This is...

Has the US dollar delivered the benefits that the rest of the world is expecting from its holdings of international liquidity? US government debt has been liquid and safe, and it is supplied in sufficient quantity. But it has given a low return to the countries that accumulated the most...

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al. (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

There is a broad consensus in the literature that costs of information processing and acquisition may generate costly disagreements in expectations among economic agents, and that central banks may play a central role in reducing such dispersion in expectations. This paper analyses empirically...

This paper reviews recent research on central bank independence (CBI). After we have distinguished between independence and conservativeness, the literature on optimal inflation contracts is discussed, followed by research in which the inflationary bias is endogenized. Finally, the various...
