This paper presents a broad overview of postwar analytical thinking on international macroeconomics, culminating in a more detailed discussion of recent progress. The paper reviews important empirical evidence that has inspired alternative modeling approaches, as well as theoretical and policy considerations behind developments in the field. The paper presents an empirical study of fiscal policy in countries with extreme monetary regimes. It also examines members of multilateral currency unions, dollarized countries that officially use the money of another country, and countries using currency boards.

This is the 2004 (Volume 51) Special Issue of IMF Staff Papers, which includes 6 selected papers (from more than 20) that were presented at the IMF's Fourth Annual Research Conference, November 6-7, 2003.

The paper discusses a model in which growth is a negative function of fiscal burden. Moreover, growth discontinuously switches from high to low as the fiscal burden reaches a critical level. The paper provides an overview of key elements of corporate bankruptcy codes and practice around the world that are relevant to the debate on sovereign debt restructuring. It also describes the broad trends in international financial integration for a sample of industrial countries and explains the cross-country and time-series variation in the size of international balance sheets.

This paper reports for uncovered interest parity (UIP) using daily data for 23 developing and developed countries during the crisis-strewn 1990s. UIP is a classic topic of international finance, a critical building block of most theoretical models, and a dismal empirical failure. UIP states that the interest differential is, on average, equal to the ex post exchange rate change. UIP may work differently for countries in crisis, whose exchange and interest rates both display considerably more volatility. This volatility raises the stakes for financial markets and central banks; it also may provide a more statistically powerful test for the UIP hypothesis. Policy-exploitable deviations from UIP are, therefore, a necessary condition for an interest rate defense. There is a considerable amount of heterogeneity in the results, which differ wildly by country.

This publication brings together a set of IMF papers that prepared as backgrounds for the various sessions of the conference and will help put into broader dissemination channels the results of this important conference. An official IMF publication is well disseminated into academic and institutional libraries and book channels. The IMF metadata will also make the conference papers more discoverable online.

This paper focuses on expectations for the American economy focused on the likelihood of secular stagnation, which continued to be debated throughout the post-war period. Concerns rose during the late 1960s and early 1970s about rapid population growth smothering the potential for economic growth in developing countries were contradicted when, during the mid- and late-1970s, fertility rates began to decline rapidly. In policy-oriented institutions (and in most businesses and individual decision making), policymaking decisions are often guided by projections and forward-looking indicators. The case of Michael Mussa has been one of great anticipation, and of great accomplishment, and all the early optimistic forecasts about him have turned out to be correct. Within the sphere of economics, undoubtedly the most famous and widely used forecast—one, incidentally, that thus far has often been incorrect—is that based on the Malthusian doctrine of the relationship between resources and population.

Movements in global capital during the late 1990s and the greater emphasis on price stability led many countries to abandon fixed exchange rate regimes and to design institutions and monetary policies to achieve credibility in the goal of lowering inflation. Such recent developments have brought to the forefront the idea that freely mobile capital, independent monetary policy, and fixed exchange rates form an "impossible trinity." It is possible to have two of these policies, but not all three. Inflation-targeting regimes being adopted by many countries provide a way of resolving this dilemma.

The global economy has experienced four waves of rapid debt accumulation over the past 50 years. The first three debt waves ended with financial crises in many emerging market and developing economies. During the current wave, which started in 2010, the increase in debt in these economies has already been larger, faster, and broader-based than in the previous three waves. Current low interest rates mitigate some of the risks associated with high debt. However, emerging market and developing economies are also confronted by weak growth prospects, mounting vulnerabilities, and elevated global risks. A menu of policy options is available to reduce the likelihood that the current debt wave will end in crisis and, if crises do take place, will alleviate their impact.

This paper provides new evidence of the macroeconomic effects of public investment in advanced economies. Using public investment forecast errors to identify the causal effect of government investment in a sample of 17 OECD economies since 1985 and model simulations, the paper finds that increased public investment raises output, both in the short term and in the long term, crowds in private investment, and reduces unemployment. Several factors shape the macroeconomic effects of public investment. When there is economic slack and monetary accommodation, demand effects are stronger, and the public-debt-to-GDP ratio may actually decline. Public investment is also more effective in boosting output in countries with higher public investment efficiency and when it is financed by issuing debt.
