Domestic Petroleum Product Prices and Subsidies: Recent Developments and Reform Strategies
Description: The paper reviews recent developments in the pass-through of international to domestic petroleum product prices, in the different fuel pricing regimes, and in fuel subsidies in a range of emerging market and developing economies. The main finding of the paper is the limited price pass-through in many countries and the consequent increase in fuel subsidies. The paper proposes that key elements of a successful strategy to contain subsidies should comprise: making subsidies explicit; making pricing mechanisms more robust; combining reductions in subsidies with measures to protect the poorest; using the resulting savings well, and transparency and consultation.

Can Regional Integration Accelerate Development in Africa? CGE Model Simulations of the Impact of the SADC FTA on the Republic of Madagascar
Description: Madagascar plans to start phasing out its customs tariffs on imports from the Southern African Development Community in 2007. This paper uses a CGE model to evaluate the impact of the SADC FTA on Madagascar economy. The results suggest that the SADC FTA would only have a limited impact on Madagascar's real GDP because the liberalization affects only a small share of its total imports. However, Madagascar's trade and production pattern would change and benefit the textile and clothing sector. Removing rigidities in the labor and capital market would increase the gains but they would remain limited. Gains from the SADC FTA become substantial only when the regional liberalization is accompanied by a multilateral liberalization.

Growth in the Dominican Republic and Haiti: Why has the Grass Been Greener on One Side of Hispaniola?
Description: The Dominican Republic and Haiti share the island of Hispaniola and are broadly similar in terms of geography and historical institutions, yet their growth performance has diverged remarkably. The countries had the same per capita real GDP in 1960 but, by 2005, the Dominican Republic's per capita real GDP had tripled whereas that of Haiti had halved. Drawing on the growth literature, the paper explains this divergence through a combined approach that includes a panel regression to study growth determinants across a broad group of countries, and a case study framework to better understand the specific policy decisions and external conditions that have shaped economic outcomes in the Dominican Republic and Haiti. The paper finds that initial conditions cannot fully explain the growth divergence, but rather policy decisions have played a central role in the growth trends of the two countries. This Working Paper should not be reported as representing the views of the IMF. The views expressed in this Working Paper are those of the author(s) and do not necessarily represent those of the IMF or IMF policy. Working Papers describe research in progress by the author(s) and are published to elicit comments and to further debate.

The Macroeconomic Effects of Migration from the New European Union Member States to the United Kingdom
Description: The United Kingdom allowed workers from the ten new European Union member countries immediate access to its labor market after the accession in 2004. This paper uses a general equilibrium framework to explore the dynamic adjustment of the UK economy to the postaccession surge in immigration. Simulations show that immigration is likely to have positive effects on economic growth, capital accumulation, consumption, and the public finances.

Policies, Enforcement, and Customs Evasion: Evidence from India
Description: We examine the effect of tariff policies on evasion of customs duties, in the context of the trade reform in India of the 1990s. We exploit the variation in tariff rates across time and products to identify the evasion elasticity, namely, the effect of tariffs on evasion, and relate this elasticity to factors related to customs enforcement or the quality of customs institutions. We find a positive and robust effect of tariffs on import tax evasion. We then show that the evasion elasticity is influenced by certain product characteristics that determine how easy it is to detect evasion (with more differentiated products exhibiting a higher evasion elasticity). This evasion elasticity, which we broadly interpret as reflecting the quality of customs administration, has not improved over the 1990s. Finally, our results suggest that the effectiveness of customs in addressing evasion may be better in India than China, although China appears to be catching up over time.

Can the Natural Resource Curse Be Turned Into a Blessing? The Role of Trade Policies and Institutions
Description: We criticize existing empirical results on the detrimental effects of natural resource dependence on the rate of economic growth after controlling for institutional quality, openness, and initial income. These results do not survive once we use instrumental variables techniques to correct for the endogenous nature of the explanatory variables. Furthermore, they suffer from omitted variables bias as they overestimate the effect of initial income per capita and thus underestimate the speed of conditional convergence. Instead, we provide new evidence for the impact of natural resource dependence on income per capita in a systematic empirical cross-country framework. In addition to a significant negative direct impact of natural resources on income per capita, we find a significant indirect effect of natural resources on institutions. We allow for interaction effects and provide evidence that the natural resource curse is particularly severe for economic performance in countries with a low degree of trade openness. Adopting policies directed toward more trade openness may thus soften the impact of a resource curse. We also check the robustness of our results by using a variety of instruments and also employing the ratio of natural capital rather than natural resource exports to national income as an explanatory variable. We find evidence that resource abundance, measured by the stock of natural capital, also induces a resource curse, but less severely for countries that are relatively open.

The Quest for Price Stability in Central America and the Dominican Republic*
Description: This paper addresses the question of why inflation has not yet converged to price stability in Central America and the Dominican Republic and is currently relatively high by Latin American standards. It suggests that despite the institutional strengthening of monetary policy, important flaws remain in most central banks, in particular a lack of a clear policy mandate and little political autonomy, which are adversely affecting the consistency of policy implementation. Empirical analysis reveals that all central banks raise interest rates to curtail inflation but only some of them increase it sufficiently to effectively tackle inflation pressures. It also shows that some central banks care simultaneously about exchange rate stability. The potential policy conflict arising from a dual central bank mandate and the unpredictable policy response is probably undermining markets' confidence in central banks' commitment to price stability, thereby perpetuating an inflation bias.

The Prospects for Sustained Growth in Africa: Benchmarking the Constraints
Description: A dozen countries had weak institutions in 1960 and yet sustained high rates of growth subsequently. We use data on their characteristics early in the growth process to create benchmarks with which to evaluate potential constraints on sustained growth for sub-Saharan Africa. This analysis suggests that what are usually regarded as first-order problems-broad institutions, macroeconomic stability, trade openness, education, and inequality-may not now be binding constraints in Africa, although the extent of ill-health, internal conflict, and societal fractionalization do stand out as problems in contemporary Africa. A key question is to what extent Africa can rely on manufactured exports as a mode of "escape from underdevelopment," a strategy successfully deployed by almost all the benchmark countries. The benchmarking comparison specifically raises two key concerns as far as a development strategy based on expanding exports of manufactures is concerned: micro-level institutions that affect the costs of exporting, and the level of the real exchange rate-especially the need to avoid overvaluation.

External Debt and Economic Reform: Does a Pain Reliever Delay the Necessary Treatment?
Description: Recent literature argues that conflict in shifting adjustment costs between different socioeconomic groups delays necessary reforms and finds that such reforms often follow economic crises. This paper expands these models by including external borrowing by the private sector and shows that this may lead to a further delay in economic reform. Empirical evidence based on a large panel of developing and emerging economies supports this argument and shows that the result is slower economic growth. External financing sometimes acts like a "pain reliever," postponing the much needed "treatment" of a "sick" economy by reform.

Financial Globalization and the Governance of Domestic Financial Intermediaries
Description: We model an economy in which domestic banks and firms face incentive constraints, as in Holmstrom and Tirole (1997). Firms borrow from banks and uninformed investors, and can collude with banks to reduce the intensity of monitoring. We study the general equilibrium effects of capital flows (portfolio investments and loans, FDI) on the governance of domestic banks. We find that liberalization of capital flows may deteriorate the governance of the domestic financial system by increasing firms' incentives to collude with banks, with negative effects on productivity. We also show that systemic bailout guarantees increase the risks of collusion.
