Attaining Selected Sustainable Development Goals in Guatemala: Spending, Provision, and Financing Needs
Description: Raising living standards continues to be the main challenge facing Guatemala, as a matter of economic success and social cohesion. This paper discusses the spending, financing, and delivery capacity aspects of a viable development strategy for Guatemala couched within the United Nations Sustainable Development Goals (SDGs) agenda. Overall, Guatemala faces additional spending of about 8½ percent of GDP in 2030 to attain health, education, and roads, water, and sanitation infrastructure SDGs. While substantial, these cost estimates are commensurate with a well-defined financing strategy encompassing continuing tax administration efforts, broad-based tax reform, scaled-up private sector participation, and greater spending efficiency. Improving delivery capacities is also essential to secure access of those public goods to all Guatemalans, irrespective of their place of residence, ethnic group, or ability to pay.

Liquidity Management under Fixed Exchange Rate with Open Capital Account
Description: This paper introduces a theoretical framework for liquidity management under fixed exchange rate arrangement, derived from the price-specie flow mechanism of David Hume. The framework highlights that the risk of short-term money market rates un-anchoring from the uncovered interest rate parity due to money and foreign exchange market frictions could jeopardize financial stability and market development. The paper then discusses operational solutions that stabilize money market rates close to the level implied by the Uncovered Interest Rate Parity (UIP). Liquidity management under fixed exchange rate with an open capital account presents specific challenges due to: (1) the larger liquidity shocks induced by foreign reserve swings that challenge the development of money markets; and (2) more complicated liquidity forecasts. The theoretical framework is empirically tested based on the estimate of “offset” coefficients for Denmark and Hong Kong SAR.

Two-Sided Market, R&D and Payments System Evolution
Description: It takes many years for more efficient electronic payments to be widely used, and the fees that merchants (consumers) pay for using those services are increasing (decreasing) over time. We address these puzzles by studying payments system evolution with a dynamic model in a twosided market setting. We calibrate the model to the U.S. payment card data, and conduct welfare and policy analysis. Our analysis shows that the market power of electronic payment networks plays important roles in explaining the slow adoption and asymmetric price changes, and the welfare impact of regulations may vary significantly through the endogenous R&D channel.

More Work to Do? Taking Stock of Latin American Labor Markets
Description: We analyze the performance of labor markets in Latin America since the late 1990s. Strong GDP growth during the commodity boom period led to important gains in employment and a fall in the unemployment rate as labor demand outpaced an increasing labor supply. We emphasize the role of informality in the dynamics of labor markets in Latin America. A re-examination of Okun’s law shows that informality dampens changes in unemployment accompanying output fluctuations. Moreover, we present some evidence that countries with higher redundancy costs and cumbersome dismissal regulations, exhibit “excess” informality over and above what would be expected based on their income and educational levels. Labor market reforms could thus contribute to reducing informality and increasing the responsiveness of labor markets to output growth. However, looking at selected case studies of reforms using the synthetic control method, we find mixed results in terms of labor market outcomes.

Policy Trade-Offs in Building Resilience to Natural Disasters: The Case of St. Lucia
Description: Resilience to climate change and natural disasters hinges on two fundamental elements: financial protection —insurance and self-insurance— and structural protection —investment in adaptation. Using a dynamic general equilibrium model calibrated to the St. Lucia’s economy, this paper shows that both strategies considerably reduce the output loss from natural disasters and studies the conditions under which each of the two strategies provides the best protection. While structural protection normally delivers a larger payoff because of its direct dampening effect on the cost of disasters, financial protection is superior when liquidity constraints limit the ability of the government to rebuild public capital promptly. The estimated trade-off is very sensitive to the efficiency of public investment.

The Russian State’s Size and its Footprint: Have They Increased?
Description: The short answer: The size of the Russian State has not increased much in the last few years, but its economic footprint remains significant. Concretely, the state's size increased from about 32 percent of GDP in 2012 to 33 percent in 2016, not far from the EBRD's estimate of 35 percent for 2005-10. This is different from the mainstream narrative, which contends that the state's size doubled in the last decade. However, a deep state footprint is reflected in a relatively high state share in formal sector activity (close to 40 percent) and formal sector employment (about 50 percent). The deep footprint is also reflected in market competition and efficiency. Although sectors in which the state is present are more concentrated, concentration is large even in sectors where the state's share is low. This suggests the need to protect and promote competition, in particular in state procurement. Finally, state-owned enterprises' performance appears weaker than that of privately-owned firms, which may be subtracting from growth.

Determinants of Currency Composition of Reserves: a Portfolio Theory Approach with an Application to RMB
Description: The way central banks manage their foreign reserve assets has evolved over the past decades. One major trend is managing reserves in two or more tranches—liquidity tranche and investment tranche—especially for those with adequate reserves. Incorporating reserve tranching, we have developed in this paper a central bank’s reserve portfolio choice model to analyze the determinants of the currency composition of reserves. In particular, we adopt the classical mean-variance framework for the investment tranche and the asset-liability framework for the liquidity tranche. Building on these frameworks, the roles of currency compositions in imports invoicing and short-term external debt, and risk and returns of reserve currencies can be quantified by our structural model—a key contribution of our paper given the absence of structural models in the literature. Finally, we estimate the potential paths of the share of RMB in reserves under different scenarios to shed light on its status as an international currency.

Fiscal Redistribution and Social Welfare
Description: Fiscal policy is a key tool for achieving distributional objectives in advanced economies. This paper embeds the discussion of fiscal redistribution within the standard social welfare framework, which lends itself to a transparent and practical evaluation of the extent and determinants of fiscal redistribution. Differences in fiscal redistribution are decomposed into differences in the magnitude of transfers (fiscal effort) and in the progressivity of transfers (fiscal progressivity). Fiscal progressivity is further decomposed into differences in the distribution of transfers across income groups (targeting performance) and in the social welfare returns to targeting due to varying initial levels of income inequality (targeting returns). This decomposition provides a clear distinction between the concepts of progressivity and targeting, and clarifies the relationship between them. For illustrative purposes, the framework is applied to data for 28 EU countries to determine the factors explaining differences in their fiscal redistribution and to discuss patterns in fiscal redistribution highlighted in the literature.

China’s Evolving Exchange Rate Regime
Description: China’s exchange rate regime has undergone gradual reform since the move away from a fixed exchange rate in 2005. The renminbi has become more flexible over time but is still carefully managed, and depth and liquidity in the onshore FX market is relatively low compared to other countries with de jure floating currencies. Allowing a greater role for market forces within the existing regime, and greater two-way flexibility of the exchange rate, are important steps to build on the progress already made. This should be complemented by further steps to develop the FX market, improve FX risk management, and modernize the monetary policy framework.

Do Fiscal Rules Cause Better Fiscal Balances? A New Instrumental Variable Strategy
Description: This paper estimates the causal effect of fiscal rules on fiscal balances in a panel of 142 countries over the period 1985-2015. Our instrumental variable strategy exploits the geographical diffusion of fiscal rules across countries. The intuition is that reforms in neighboring countries may affect the adoption of domestic reforms through peer pressure and imitational effects. We find that fiscal rules correlate with lower deficits, but the positive link disappears when endogeneity is correctly addressed. However, when considering an index of fiscal rules’ design, we show that well-designed rules have a statistically significant impact on fiscal balances. We conduct several robustness tests and show that our results are not affected by weak instrument problems.
