Beyond Macroeconomic Stability: The Quest for Industrialization in Uganda
Description: Uganda has registered one of the most impressive economic turnarounds of recent decades. The amelioration of conflict and wide ranging economic reforms kick-started rapid economic growth that has now been sustained for some 20 years. But there is a strong sense in policy making circles that despite macroeconomic stability and reasonably well functioning markets, economic growth has not translated into significant structural transformation. This paper considers (i) Uganda's record of economic transformation relative to the high growth Asian countries and (ii) the contending explanations as to why more transformation and higher growth has proved elusive.

Garbage In, Gospel Out? Controlling for the Underreporting of Remittances
Description: Empirical studies that use self-reported data on remittances to measure the latter's impact on microeconomic incentives mostly ignore the potential errors associated with reporting/measurement issues. An econometric procedure to control for these errors is developed and applied to household-level data from Armenia. We find evidence of systematic under-reporting of remittances. After controlling for this, we find a strong negative impact of remittances on incentives to work.

Banks and Labor as Stakeholders: Impact on Economic Performance
Description: Traditionally, the impacts of the rights of financial institutions and workers on corporate performance have been analyzed independently. Yet, theory clearly indicates that the combination of relative powers of different stakeholders affects a firm overall performance. Using U.S. state level and state-industry level data, we investigate how output growth is affected by bank branch deregulation and employment protection occurring over 1972-1993. We find that financial liberalization positively impact overall state growth but greater workers' rights affects it ambiguously. At the industry level, however, employment protection promotes those industries that are more knowledge intensive, while the effect of financial liberalization does not differ across industries that vary in external financing dependency. The results hold controlling for changes in shareholders' rights, which itself is not significant. The findings suggest that financial liberalization operates mostly through an efficiency channel, better reallocating resources across sectors, while employment protection creates higher incentives and encourages more sector-specific, human capital investments. Overall, the results show that the strength of stakeholders' protection affects performance through efficiency channels and provide support for a stakeholders' view of corporate governance.

Current and Proposed Non-Oil Tax System in Azerbaijan
Description: This paper analyzes developments in non-oil tax policy, administration, and revenues in Azerbaijan, and suggests measures for further improvement. The main finding is that Azerbaijan's non-oil tax revenues increased significantly as a share of non-oil GDP in the last five years, but remain below potential. The non-oil tax revenue shortfall is mainly due to widespread exemptions, but there is scope for strengthening tax and customs administration. In the short term, expanding the tax base and better tax and customs administration will yield more revenues. In the medium term, more far-reaching reforms including reducing some direct tax rates, should be considered. The overall reform package could be made broadly revenue neutral by improving taxpayers' compliance and reducing exemptions.

Central Bank Collateral Frameworks: Principles and Policies
Description: Central bank collateral policies came under pressure with the 2007-08 financial market crisis. This paper addresses the rationale for and constraints in taking collateral, and recent practices in different collateral frameworks. It then considers the risks of adverse selection. The paper concludes that (i) the collateral framework needs to include market incentives; (ii) central banks face trade-offs between risk and counterparty access; (iii) emerging markets may see pressure on collateral policies in coming years; and (iv) further work is required to develop pricing incentives and the structure of central bank facilities, both during normal times and in periods of market stress.

Commodities and the Market Price of Risk
Description: Commodities are back following a stellar run of price performance, attracting financial investor attention. What are the fundamental reasons to hold commodities? One reason is the exposure offered to underlying risk factors. In this paper, I assess the macro risk exposure offered by commodity futures and test whether these risks are priced, using Merton's (1973) intertemporal capital asset pricing model for a sample of commodity prices covering the period January 1973 - February 2008. I find that commodity futures offer a hedge against lower interest rates and that investors are willing to accept lower expected returns for this position. Although some commodities are also a hedge against U.S. dollar depreciation, this risk is not priced.

Banking Structure and Credit Growth in Central and Eastern European Countries
Description: Recent developments have increased questions about vulnerabilities in Central and Eastern European Countries (CEE) that are experiencing credit booms. This paper analyzes the role of foreign-owned banks in these credit booms. The results show that the CEE countries depend on foreign banks, and these foreign banks depend on interbank funding. Lending by foreign banks seems driven by economic growth and interest rate margins. This lending appears independent of economic but not financial conditions in the foreign bank's home country.

Mauritius: A Competitiveness Assessment
Description: We assess the competitiveness of Mauritius in recent years using two approaches. First, we estimate the difference between the equilibrium and the actual real exchange rate using four methods: the macroeconomic balance approach, the single-equation fundamentals approach, the capital-enhanced approach, and the external sustainability approach. The methods consistently suggest that at the end of 2007 the exchange rate was aligned with its equilibrium value. Second, we undertake a comparative analysis of structural competitiveness indicators and find that Mauritius often fares better on business climate than other small island economies and high-growth Asian economies. Nevertheless, there are areas for improvement.

Central Bank Response to the 2007–08 Financial Market Turbulence: Experiences and Lessons Drawn
Description: The paper reviews the policy response of major central banks during the 2007–08 financial market turbulence and suggests that there is scope for convergence among central bank operational frameworks through the adoption of those elements that proved most instrumental in calming markets. These include (i) rapid liquidity provision to a broad range of counterparties; (ii) a congruence of collateral policies with market developments; (iii) an ability to increase the average maturity of liquidity provision; and (iv) central bank cooperation to facilitate the use of cross-border collateral. Flexible use of open market operations was needed to avoid the stigma associated with traditional standing facilities, and allowed central banks to maintain at least basic market functioning. Having a flexible framework, however, requires careful consideration of the desirable limits to market intervention.

Global Volatility and Forex Returns in East Asia
Description: During 2001-07, increases in mature market volatility were associated with declines in forex returns for East Asian countries, consistent with an overall "flight to safety" effect. Estimates from GARCH models suggest that a 5 percentage point increase in mature market equity volatility generated an exchange rate depreciation of up to ½ percent. This sensitivity rose during the latter period in the sample, suggesting greater integration of Asian financial markets with global markets. Unconditional standard deviations estimated from these models also provide operational measures of "long-term" and "excess" volatility in forex markets. Long-run forex volatility declined as Asian economies settled down with generally stronger fundamentals in the post-crisis period to more flexible regimes along with a generally lower level of mature market volatility.
