This paper presents an update of the Grilli-Masciandaro-Tabellini (GMT) index of central bank (CB) autonomy, based on CB legislation as of end-2003. The index is applied to a set of OECD and developing countries, and emerging market economies. For a smaller set of countries, the paper presents a...

This paper proposes a probabilistic approach to public debt sustainability analysis (DSA) using ""fan charts."" These depict the magnitude of risks-upside and downside-surrounding public debt projections as a result of uncertain economic conditions and policies. We propose a simulation algorithm...

We present a model of the optimal level of international reserves for a small open economy that is vulnerable to sudden stops in capital flows. Reserves allow the country to smooth domestic absorption in response to sudden stops, but yield a lower return than the interest rate on the country''s...

This paper discusses important tax policy issues facing developing countries today. It views tax policy from both the macroeconomic perspective, which focuses on broad questions such as the level and composition of tax revenue, and the microeconomic perspective, which focuses on certain design...

Emerging market financial crises are abrupt and dramatic, usually occurring after a period of high output growth, massive capital flows, and a boom in asset markets. This paper develops an equilibrium asset-pricing model with informational frictions in which vulnerability and the crisis itself...

This paper exploits a panel dataset comprising 1,565 banks in 20 emerging countries during 1989- 2001 and compares the response of the volume of loans and the rates on loans and deposits to various measures of monetary conditions across domestic and foreign banks. It also looks for systematic...

This paper analyses the fiscal effects of armed conflict and terrorism on low- and middle-income countries. An analysis of 22 conflict episodes shows that armed conflict is associated with lower growth and higher inflation, and has adverse effects on tax revenues and investment. It also leads to...

This paper develops a simple model of foreign debt portfolio management. The model suggests that, under mild conditions, the currency composition of a country''s foreign debt portfolio is responsive to exchange rate movements. Empirical evidence is provided for a panel of 14 emerging economies...

This paper assembles a new dataset on corporate income tax regimes in 50 emerging and developing economies over 1996-2007 and analyzes their impact on corporate tax revenues and domestic and foreign investment. It computes effective tax rates to take account of complicated special regimes, such...
