Product Market Regulation and the Benefits of Wage Moderation
Description: Euro-area real wages have decelerated sharply in the last 20 years, but this has not yet translated into visibly lower unemployment or faster growth. Weak output growth after such a cost shock is somewhat puzzling and has led some to question the benefits of wage moderation. By isolating structural from cyclical factors in a panel of industrial countries, I show that structurally slower real wage growth, that is, "wage moderation," does raise output growth and lower unemployment rates. However, I show that the impact on both variables depends crucially on product market regulation: weaker competition and barriers to entry mute the growth effects of structural real wage changes by allowing incumbent firms to appropriate larger rents. In this context, overly regulated product markets in the euro area are undermining the effects of labor market reforms on output and employment.

Russia's Regions: Income Volatility, Labor Mobility and Fiscal Policy
Description: Russia's regions are heavily exposed to regional income shocks because of an uneven distribution of natural resources and a Soviet legacy of heavily skewed regional specialization. Also, Russia has a limited mobility of labor and lacks fiscal instruments to deal with regional shocks. We assess how these features influence the magnitude and persistence of regional income shocks, through a panel vector autoregression, drawing on extensive and unique regional data covering last decade. We find that labor mobility associated with regional shocks is far lower than in the United States yet higher than in the EU-15, and that regional expenditures tend to expand in booms and contract in recessions. We discuss institutional factors behind these outcomes and policy implications.

Governance Structures and Decision-Making Roles in Inflation-Targeting Central Banks
Description: This paper surveys decision-making roles of governing bodies of central banks that have formally adopted inflation targeting as a monetary framework. Governance practices seek to balance institutional independence needed for monetary policy credibility with accountability required to protect democratic values. Central bank laws usually have price stability as the primary monetary policy objective but seldom require an explicit numerical inflation target. Governments are frequently involved in setting targets, but to ensure operational autonomy, legal provisions explicitly limit government influence in internal policy decision-making processes. Internal governance practices differ considerably with regard to the roles and inter-relationships between the policy, supervisory, and management boards of a central bank.

European Union Enlargement and Equity Markets in Accession Countries
Description: The announcement of the European Union enlargement coincided with a dramatic rise in stock prices in accession countries. This paper investigates the hypothesis that the rise in stock prices was a result of the repricing of systematic risk due to the integration of accession countries into the world market. We found that firm-level stock price changes are positively related to the difference between a firm's local and world market betas. This result is robust to controlling for changes in expected earnings, country effects, and other controls, although the magnitude of the effect is not very large. The differences between local and world betas explain nearly 22 percent of the stock price increase.

A Global View of the U.S. Investment Position
Description: This paper analyzes various indicators of the U.S. international investment position from a portfolio perspective. The 1990s saw a decline in home bias, which, coupled with rapid financial deepening, led to a large increase in gross international investment holdings. The home bias of non-U.S. investors declined more rapidly than that of U.S. investors, allowing the United States to finance a rising stock of net liabilities, even as foreign portfolios remained marketweight or underweight U.S. assets in each investment category. However, a comparison to other countries reveals that the U.S. net international investment position (NIIP) is large given the size of the economy and is deteriorating, especially through a growing negative net debt securities position.

Pity the Finance Minister: Issues in Managing a Substantial Scaling-Up of Aid Flows
Description: Substantially scaling up of aid flows will require development partners to address many issues, including the impact of higher aid flows on: the competitiveness of aid recipients; the management of fiscal and monetary policy; the delivery of public services; behavioral incentives; and the rate of growth of the economy. Other issues will include the appropriate sequencing of aid-financed investments; balancing alternative expenditure priorities; the implications for fiscal and budget sustainability; and exit strategies from donor funding. Donors will need to ensure greater long-term predictability and reduced short-term volatility of aid. The international financial institutions can play a critical role in helping countries address these scaling-up issues.

How Useful is Monetary Econometrics in Low-Income Countries? T+L3104he Case of Money Demand and the Multipliers in Rwanda
Description: This paper revisits the usefulness of econometric monetary analysis in low-income countries in a case study on Rwanda, an interesting case given its floating exchange rate and reliance on indirect monetary policy instruments on the one hand, and its somewhat typical data and institutional shortcomings on the other hand. The findings are generally encouraging for the use of econometric models for monetary analysis in low-income countries. Notwithstanding substantial qualifications, time series and structural models of the money multiplier and money demand yield results that are statistically and economically reasonable enough to usefully inform policymaking.

Explicit and Implicit Targets in Open Economies
Description: Under a flexible inflation targeting regime, should policymakers avoid any reaction to movements in the foreign exchange market? Using data for six advanced open economies explicitly targeting inflation, the paper examines empirically whether real exchange rate disequilibria systematically affect the conduct of monetary policy. Estimates indicate that monetary policy responses in inflation-targeting, open economies have changed significantly, as the institutional framework for the conduct of monetary policy has evolved. In particular, an explicit target for core inflation and a greater use of the expectation channel of monetary policy appear to be key features of the newest policy framework. In this context, central banks are unlikely to react to regular fluctuations in the exchange rate.

The Political Economy of Seigniorage
Description: While most economists agree that seigniorage is one way governments finance deficits, there is less agreement about the political, institutional, and economic reasons for relying on it. This paper investigates the main determinants of seigniorage using panel data on about 100 countries, for the period 1960-1999. Estimates show that greater political instability leads to higher seigniorage, especially in developing, less democratic, and socially polarized countries, with high inflation, low access to domestic and external debt financing and with higher turnover of central bank presidents. One important policy implication of this study is the need to develop institutions conducive to greater economic freedom as a means to lower the reliance on seigniorage financing of public deficits.

Commodity Price Shocks and the Oddson Fiscal Performance
Description: Unanticipated changes in commodity prices can generate significant movements in fiscal aggregates. This paper seeks to understand the dynamics of these fiscal movements in the context of transitory commodity price shocks using sample data from four CIS countries- two oil-producing and two non-oil commodity-intensive countries. It adopts a structural VAR approach and identifies the dynamic effects of commodity price shocks on fiscal performance under two broad tax regimes. Stochastic simulations indicate high probabilities of fiscal overperformance in the short term when commodity prices are high. These probabilities deteriorate significantly, however, in the long term after the transitory positive commodity price shock has dissipated, particularly when lax fiscal policy is adopted during the period of the price boom.
