Convergence in Emerging Europe: Sustainability and Vulnerabilities
Description: The emerging European economies have been converging rapidly towards the more advanced European economies in recent years. However, large external imbalances in parts of the region have raised questions about sustainability and concerns about vulnerabilities. Empirical evidence in this paper suggest that the convergence trend of emerging Europe is based on strong fundamentals and is expected to continue, but at a slower pace. Moreover, the convergence path may be volatile as countries with large external imbalances adjust, with risks of a hard landing in some cases.

The Impact of Research and Development Tax Incentives on Colombia’s Manufacturing Sector: What Difference Do They Make?
Description: Do tax incentives for science and technology stimulate additional investment? We use detailed data on applications and acceptances for R&D tax incentives, a special survey, and for the first time, the science and technology module from the 2000-2002 Survey of Manufacturers database in Colombia to analyze this question. We estimate the effect of the R&D tax deduction instituted in Colombia using Zellner's Seemingly Unrelated Regressions method, and find that the elasticity of demand of R&D investment in manufacturing is quite high in Colombia compared to other countries, particularly for smaller firms, but that the direct benefit from existing policies is minimal. Overall, the results of the paper suggest that there is a great potential for such incentives to promote R&D investment in Colombia, but in their current form, they fail to target those firms that could benefit the most.

Consumer Confusion: The Choice of AFORE
Description: This paper was prepared for the World Bank 4th Annual Contractual Savings Conference (Washington DC, April 2008) co-organized by Gregorio Impavido (gimpavido@imf.org). The article shows that account transfers among pension administrators in Mexico barely respond to price or return considerations and in general has not improved the consumer's pension balance. Instead of strengthening competition through lower fees and higher returns for the consumer, AFORE switching has so far undermined the system and resulted in the destruction of value. Moreover, "noisy" evaluations of the product by the consumer tend to undermine the power of competition. Thus, an increased number of pension fund managers has not provided a more competitive environment. The theoretical framework allows for the estimation of "noise" and mark-ups in the AFORE industry. As the number of AFOREs increases, the mark-up diminishes at a very slow rate. This implies that more participants in the industry will hardly affect prices.

Inflation Smoothing and the Modest Effect of VAT in Germany
Description: Increases in German core inflation following the 2007 VAT hike were smaller than expected, leading to speculation about delayed inflationary effects. This paper argues to the contrary that price increases in advance of the VAT hike explain the small increase upon implementation. We find that core inflation rose by 0.36 percentage point in the run up and by a further 0.40 percentage point at the time of the VAT hike. Cumulatively, the tax hike contributed to two thirds of the increase in core inflation in 2006-07 at an estimated pass-through of 73 percent. Most of the increase in 2006 was of general nature, while about one sixth can be attributed to durable goods and items with low degree of competition.

A Framework for Developing Secondary Markets for Government Securities
Description: This paper consolidates previous work on the development of secondary markets for government securities, and focuses on the sequencing of measures necessary for their development. Six main lessons are identified: (i) a commitment to achieving and maintaining a stable macroeconomic environment, especially prudent fiscal policy, should underpin market development; (ii) a sound and transparent public debt management strategy supports secondary market activity; (iii) a deep and diverse investor base is required; (iv) poor market infrastructure leads to high transaction costs, slow order execution, and excessive operational risk, which all inhibit trading; (v) secondary market growth is facilitated by effective monetary policy implementation; and (vi) reforms should be sequenced to ensure even development of all the structures supporting the secondary market.

The ECB’s Monetary Analysis Revisited
Description: Monetary aggregates continue to play an important role in the ECB's policy strategy. This paper revisits the case for money, surveying the ongoing theoretical and empirical debate. The key conclusion is that an exclusive focus on non-monetary factors alone may leave the ECB with an incomplete picture of the economy. However, treating monetary factors as a separate matter is a second-best solution. Instead, a general-equilibrium inspired analytical framework that merges the economic and monetary "pillars" of the ECB's policy strategy appears the most promising way forward. The role played by monetary aggregates in such unified framework may be rather limited. However, an integrated framework would facilitate the presentation of policy decisions by providing a clearer narrative of the relative role of money in the interaction with other economic and financial sector variables, including asset prices, and their impact on consumer prices.

Credit Matters: Empirical Evidence on U.S. Macro-Financial Linkages
Description: This paper develops a framework for analyzing macro-financial linkages in the United States. We estimate the effects of a negative shock to banks' capital/assetratio on lending standards, which in turn affect consumer credit, mortgages, and corporate loans, and the corresponding components of private spending (consumption, residential investment and business investment). In addition, our empirical model allows for feedback from spending and income to bank capital adequacy and credit. Hence, we trace the full credit cycle. An exogenous fall in the bank capital/asset ratio by one percentage point reduces real GDP by some 1½ percent through its effects on credit availability, while an exogenous fall in demand of 1 percent of GDP is gradually magnified to around 2 percent through financial feedback effects.

The Distributional Impact of Fiscal Policy in Honduras
Description: This paper uses household survey data to estimate the incidence of tax and spending programs in Honduras. Any such exercise is fraught with difficulty, so our simplifying assumptions are carefully explained. Rather than look at tax and spending completely independently, we evaluate net incidence of major programs-such as health care and pensions-to get a more holistic evaluation of redistribution. Our results show that fiscal policy is, on balance, progressive, but that there is room for significant improvement. In particular, energy subsidies, university education and public pension programs provide disproportionate benefits to higher-income households.

Reforming Government Subsidies in the New Member States of the European Union
Description: Subsidy reform has been a key component of the pre-accession reform agenda of the 10 new member states that joined the EU in 2004 (EU-10). During the pre-accession period, these countries had to undertake a number of important structural reforms in their economies. One of the most critical reforms was to reduce, and in some cases, eliminate their subsidy programs. This paper analyzes how key subsidy reforms (in state aid to enterprises, agriculture, energy, and transportation) were carried out in the EU-10 during 1995–2005, and explains observed variations across types of subsidies and across countries. Based on an extensive qualitative analysis, the paper draws lessons for future successful reforms of government subsidies. 32B

Strategic Interactions between an Independent Central Bank and a Myopic Government with Government Debt
Description: We analyse optimal discretionary games between a benevolent central bank and a myopic government in a New Keynesian model. First, when lump-sum taxes are available and public debt is absent, we show that a Nash game results in too much government spending and excessively high interest rates, while fiscal leadership reinstates the cooperative outcome under discretion. Second, we show that this familiar result breaks down when lump-sum taxes are unavailable. With government debt, the Nash equilibrium still entails too much public spending but leads to lower interest rates than the cooperative policy, because debt has to be adjusted back to its pre-shock level to ensure time consistency. A setup of fiscal leadership does not avoid this socially costly outcome. Imposing a debt penalty onto the myopic government under either Nash or fiscal leadership raises welfare substantially, while appointing a conservative central bank is less effective.
