Modeling Aggregate Use of Fund Resources—Analytical Approaches and Medium-Term Projections
Description: This paper presents two approaches to modeling the use of IMF resources in order to gauge whether the recent decline in credit outstanding is a temporary or a permanent phenomenon. The two approaches-the time series behavior of credit outstanding and a two-stage program selection and access model-yield the same conclusion: the use of IMF resources is likely to decline sharply. Specifically, credit outstanding is projected to decline from an average of SDR 50 billion over 2000?05 to SDR 8 billion over 2006?10. Stochastic simulations suggest that it is unlikely to be much higher. These results are based on WEO projections with a correction for historically-observed over-optimistic biases. Alternative scenarios assuming a weaker economic performance or a less benign global environment do not alter these results.

Will a Regional Bloc Enlarge?
Description: This paper investigates whether a regional bloc would enlarge or remain stagnant in size using a model where enlargement is the endogenous outcome of the interaction between the supply of and demand for membership. We show that a maximum size of the bloc exists beyond which the regional policy-maker will be unwilling to enlarge further, and that either the supply side or the demand side of membership might be binding in the determination of the equilibrium size of the bloc. Furthermore, we analyze how the deepening of integration within a regional bloc affects its width. We show that deeper integration may lead to wider integration when the demand side of membership is binding in the determination of the equilibrium size of the bloc, while the equilibrium size of the bloc will be unaffected when the supply side of membership is binding.

Politically Optimal Fiscal Policy
Description: Why do governments issue large amounts of debt? In what sense and for whom is such a policy optimal? We show that twisting the optimal taxation paradigm produces very reasonable predictions for debt and real interest rates. Adding an extra dimension of uncertainty about the political planning horizon gives rise to a positive and very plausible government debt-to-GDP ratio of about 55 percent in a model that otherwise predicts negative government debt. We quantify the impact of political uncertainty on steady state and business cycle dynamics. We illustrate how populist tax cuts can cause business cycle fluctuations.

Public Infrastructures, Public Consumption, and Welfare in a New-Open-Economy-Macro Model
Description: This paper focuses on the trade-off faced by governments in deciding the allocation of public expenditures between productivity-enhancing public infrastructures and utility-enhancing public consumption. From the modeling point of view, the paper augments a standard New Open Economy Macroeconomics (NOEM) model by introducing productive public infrastructures. The results show that a temporary increase in the domestic stock of public capital financed by a reduction in public consumption reduces domestic welfare in the short run because the temporary gains from higher productivity do not compensate domestic residents for the utility loss due to lower public consumption. If the policy shift is permanent domestic utility is likely to increase, while foreign residents suffer short-run welfare losses but benefit from welfare gains in the long run. This analysis implies that a permanent domestic reallocation of public spending might result in a virtuous global technological cycle.

International Finance and Income Convergence: Europe is Different
Description: Recent studies conclude that the ongoing global financial integration may have had little or no value in advancing economic growth, especially in poor countries. Capital is often found to flow "uphill" from poor to rich countries. And, when it does flow into the less developed economies, it is negatively correlated with growth, calling into question the desirability of foreign capital. In this paper we report that Europe-including the new member states of the European Union-provides a counterexample to these global anomalies. With increasing financial integration, capital in Europe has traveled "downhill" from rich to poor countries, and has done so with gathering strength. These inflows have been associated with significant acceleration of income convergence.

A Primer on Sovereign Debt Buybacks and Swaps
Description: This paper sets forth some basic principles that could help debt managers in emerging market and other countries to plan and implement sovereign debt buyback and swap operations. It discusses the macroeconomic context in which buybacks and swaps are undertaken, the objectives of buybacks and swaps, the analytical framework for deciding whether to undertake a particular buyback or swap operation and for selecting among alternative operations, and some key issues in the determination of the strategy for executing buybacks and swaps. The focus is on developing the analytical framework for evaluating sovereign debt buyback and swap operations, since very little work has been done in this area. In this regard, the paper presents a step-wise decision-making procedure, in which discounted cash flow analysis and the use of strategic benchmarks for the debt play central roles.

International Evidenceon Fiscal Solvency: Is Fiscal Policy "Responsible"?
Description: This paper looks at fiscal solvency and public debt sustainability in both emerging market and advanced countries. Evidence of fiscal solvency, in the form of a robust positive conditional relationship between public debt and the primary fiscal balance, is established in both groups of countries. Evidence of fiscal solvency is much weaker, however, at high debt levels. These findings suggest that many industrial and emerging market economies, including several where fiscal solvency has been the subject of recent debates, appear to conduct fiscal policy responsibly. Yet our results cannot reject the hypothesis of fiscal insolvency in groups of countries with high debt ratios.

Are Regional Trade Agreements in Asia Stumbling or Building Blocks? Implications for the Mekong-3 Countries
Description: Is the recent proliferation of Regional Trade Agreements (RTAs) in Asia a healthy development, or runs the risk of turning into an unmanageable "noodle bowl" in the future? The goal of this paper is to shed some light on this question. The results show that membership in the Asian RTAs considered in this study have not, to date, occurred at the expense of trade with nonmembers, as most Asian countries' integration with the global economy preceded regional integration. However, looking forward, given their discriminatory nature, a proliferation of RTAs, which is not accompanied by continuing unilateral and multilateral liberalization, could run the risk of leading to costly trade diversion.

Democracy and Foreign Education
Description: Do foreign-educated individuals play a role in promoting democracy in their home countries? Despite the large amount of private and public resources spent on foreign education, there is no systematic evidence that foreign-educated individuals foster democracy in their home countries. Using a unique panel dataset on foreign students starting from 1950, I show that, indeed, foreign-educated individuals promote democracy in their home country, but only if the foreign education is acquired in democratic countries. The results are robust to reverse causality, country-specific omitted variables, and inclusion of a variety of control variables. The results are stronger for small countries.

The Lending Channel in Emerging Economies: Are Foreign Banks Different?
Description: 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 differences in the behavior of domestic and foreign banks during periods of financial distress and tranquil times. Using differences in bank ownership as a proxy for financial constraints, the paper finds weak evidence that foreign banks have a lower sensitivity of credit to monetary conditions relative to their domestic competitors, with the differences driven by banks with lower asset liquidity and/or capitalization. The lending and deposit rates of foreign banks tend to be smoother during periods of financial distress. However, the differences across domestic and foreign banks do not appear to be strong. These results provide weak support to the existence of supply-side effects in credit markets and suggest that foreign bank entry in emerging countries may have contributed somewhat to stability in credit markets.
