Did the Basel Accord Cause a Credit Slowdown in Latin America?
Description: Drawing from a unique data set comprising 2,893 banks and 152 countries over the period 1987 to 2000, we test whether the adoption of the Basel Accord by Latin American and Caribbean countries was responsible for the serious slowdowns in credit growth experienced by these countries. We find that, on average, both bank capitalization and lending activities in Latin America increased after Basel. Consequently, Basel did not seem to lead to an overall credit decline. However, we do find evidence that loan growth became more sensitive to some risk factors. Our study suggests that the upcoming adoption of Basel II might cause greater procyclicality of credit.

A (New) Country Insurance Facility
Description: To cope with the self-fulfilling liquidity runs that triggered many recent financial crises, we propose the creation of a country insurance facility. The facility, which we envisage as complementary to the existing multilateral lending facilities, would provide eligible countries with automatic access to a credit line at a predetermined interest rate. Eligibility criteria should be easily verifiable, focus on debt sustainability, and take into account the currency and maturity composition of the debt. Other critical design issues considered here include the size of the facility, its duration and charges, and the exit costs for a country that loses eligibility.

How Do Trade and Financial Integration Affect the Relationship Between Growth and Volatility?
Description: The influential work of Ramey and Ramey (1995) highlighted an empirical relationship that has now come to be regarded as conventional wisdom-that output volatility and growth are negatively correlated. We reexamine this relationship in the context of globalization-a term typically used to describe the phenomenon of growing international trade and financial integration that has intensified since the mid-1980s. Using a comprehensive new data set, we document that, while the basic negative association between growth and volatility has been preserved during the 1990s, both trade and financial integration significantly weaken this negative relationship. Specifically, we find that, in a regression of growth on volatility and other controls, the estimated coefficient on the interaction between volatility and trade integration is significantly positive. We find a similar, although less significant, result for the interaction of financial integration with volatility.

Revenue Forecasts as Performance Targets
Description: Budget revenue forecasts should be best estimates of expected receipts. Often they are not. This paper analyzes the rationale for overstated revenue forecasts and derives conditions for intentional biases. A theoretical model demonstrates that overstated revenue forecasts can be the result of the government's attempt to boost unobserved revenue collection effort. If positive forecast errors are costly and undermine public credibility of budget expenditure plans, the reverse outcome is possible and governments may understate revenue forecasts. A case study for Azerbaijan is presented in support of the former incentive motive.

Currency Crises in Developed and Emerging Market Economies: A Comparative Empirical Treatment
Description: This paper takes a step in empirically testing the implications of a number of theoretical models that attempt to highlight the dynamics behind currency crises. By focusing on countries with broadly disparate economic and political arrangements, the study attempts to determine the extent to which these variables matter in affecting the probabilities of currency crises occurring. The empirical findings provide support for the view that, in general, a deterioration in economic fundamentals and the pursuit of lax monetary policy can contribute to currency crises. The experiences of several emerging market economies suggests that the sustainability of exchange rate policy depends both on adequate policy responses to the shocks to the economy and on the fragility of the economic, financial, and political system.

Trade and Growth in the Presence of Distortions
Description: Tariffs and other policy distortions typically lower real national income relative to what it otherwise would have been for any given rate of factor accumulation. Even while lowering real income, however, policy distortions may raise an economy's real measured growth rate and so, somewhat deceivingly, give the impression that national welfare has benefited from things like tariff protection. This would be an incorrect conclusion. This paper discusses the issue of how protection can affect the rate of growth for a small, open economy. As shown by Johnson (1970), in the presence of exogenously given factor accumulation, tariffs either raise or lower an economy's growth rate (measured by the change in the value of output at world prices), relative to the no-distortion growth rate. We also discuss the relevance of this result for tariff uniformity, "tariff jumping" foreign direct investment, and the empirical literature on trade and growth. Finally we use a numerical simulation model of Egypt to assess whether the costs of its tax distortions have increased or declined over time.

Trade Costs and Real Exchange Rate Volatility: The Role of Ricardian Comparative Advantage
Description: This paper examines the impact of trade costs on real exchange rate volatility. We incorporate a multi-country Ricardian model of trade, based on the work of Eaton and Kortum (2002), into a macroeconomic model to show how bilateral real exchange rate volatility depends on relative technological differences and trade costs. These differences highlight a new channel, in which the similarity of a pair of countries' set of suppliers of traded goods affects bilateral exchange rate volatility. We then test the importance of this channel using a large panel of cross-country data over 1970-97, and find strong evidence supporting the channel.

The International Effects of Government Spending Composition
Description: This paper helps resolve a paradox in the literature, noticed by Alesina and Perotti (1995), which is that, although government employment is an important component of public spending, the debate on the effects of fiscal policy focuses almost exclusively on shocks to non-wage government consumption. We incorporate the distinction between spending for government employment and spending for non-wage government consumption in a "new open economy macroeconomics" model. Our results show that a permanent reduction in public employment in one country reduces relative private consumption and appreciates the domestic exchange rate if it is matched by a reduction in taxes. When the reduction in public employment is used to finance increased non-wage government consumption, the macroeconomic effects results are ambiguous, and are affected by the initial level of the public wage bill.

The Political Economy of Revenue-Forecasting Experience From Low-Income Countries
Description: This paper analyzes interference and timeliness in the revenue-forecasting process, using new data on revenue-forecasting practices in low-income countries. Interference is defined as the occurrence of a significant deviation from purely technical forecasts. A theoretical model explains forecasting interference through government corruption. The data broadly supports the model, and the results are robust to alternative explanations. The paper also constructs three indices-transparency, formality, and organizational simplicity-that characterize revenue-forecasting practices, and assesses their effectiveness in producing an upfront-that is, timely-budget envelope. More transparent and simple forecasting processes lead to early budget constraints, while formality has no measurable effect.

Remoteness and Real Exchange Rate Volatility
Description: This paper examines the impact of trade costs on real exchange rate volatility. The channel is examined by constructing a two-country Ricardian model of trade, based on the work of Dornbusch, Fischer, and Samuelson (1977), which shows that higher trade costs result in a larger nontradable sector. This, in turn, leads to higher real exchange rate volatility. We provide empirical evidence supporting the channel.
