Fiscal Challenges of Population Aging in Brazil
Description: In recent decades, population has been aging fast in Brazil while old age pensions and healthrelated spending have increased. As the population ages, the spending trend threaten to reach unsustainable levels absent reforms. Increasing the retirement age is key, but by itself will not provide sufficient savings to close the pension system financing gap, and reforms reducing replacement rates are necessary. In the area of health, there is scope for improving expenditure efficiency by strengthening outpatient care and regional networks, and developing clinical guidelines for cost-effective treatments and drugs. Reforms are urgent, so that they can be gradual.

Long-Run Biological Interest Rate for Pay-As-You-Go Pensions in Advanced and Developing Countries
Description: How much of an internal rate of return would a sustainable pay-as-you-go pension system offer current and future generations equally? The answer is the sum of the Long-Run Biological Interest Rates (LBIR), the real-world equivalent of Samuelson’s (1958) biological interest rate, and future productivity growth. Reflecting global population ageing, the median LBIR across 172 countries is as low as 1 percent per year. The LBIRs are particularly low in advanced countries, estimated to be negative in many of them, and require ample financial reserves today or future productivity growth to maintain participation in pension schemes. On the other hand, the LBIRs in less developed regions, such as in sub-Saharan Africa, are relatively high, indicating a potential to use a pay-as-you-go scheme to expand the coverage of public pensions. Raising the retirement age by five years brings up the LBIR by 40 basis points, significantly improving the long-run budget constraint of a pension scheme.

Assessing Corporate Vulnerabilities in Indonesia: A Bottom-Up Default Analysis
Description: Under adverse macroeconomic conditions, the potential realization of corporate sector vulnerabilities could pose major risks to the economy. This paper assesses corporate vulnerabilities in Indonesia by using a Bottom-Up Default Analysis (BuDA) approach, which allows projecting corporate probabilities of default (PDs) under different macroeconomic scenarios. In particular, a protracted recession and the ensuing currency depreciation could erode buffers on corporate balance sheets, pushing up the probabilities of default (PDs) in the corporate sector to the high levels observed during the Global Financial Crisis. While this is a low-probability scenario, the results suggest the need to closely monitor vulnerabilities and strengthen contingency plans.

Tax Administration and Firm Performance: New Data and Evidence for Emerging Market and Developing Economies
Description: Tax compliance costs tend to be disproportionately higher for small and young businesses. This paper examines how the quality of tax administration affects firm performance for a large sample of firms in emerging market and developing economies. We construct a novel, internationally comparable, and multidimensional index of tax administration quality (the TAQI) using information from the Tax Administration Diagnostic Assessment Tool. We show that better tax administration attenuates the productivity gap of small and young firms relative to larger and older firms, a result that is robust to controlling for other aspects of tax policy and of economic governance, alternative definitions of small and young firms, and measures of the quality of tax administration. From a policy perspective, we provide evidence that countries can reap growth and productivity dividends from improvements in tax administration that lower compliance costs faced by firms.

Demographic Changes in Latin America: The Good, the Bad and …
Description: The paper develops a simple, integrated methodology to project public pension cash flows and healthcare spending over the long term. We illustrate its features by applying it to the LAC5 (Argentina, Brazil, Chile, Colombia and Mexico), where public spending pressures are expected to increase significantly over 2015-50 due to demographic trends and rising healthcare costs. We simulate alternative pension reforms, including the transition from a defined benefit to a defined contribution pension system and the fiscal burden of a minimum guaranteed pension under the latter. We also analyze public healthcare outlays in the LAC5, which is likewise expected to increase significantly over 2015-50 due to aging and the so-called excess cost growth factor of healthcare services, showing that curbing the evolution of the latter (e.g., through enhanced competition in the healthcare sector) could aid in containing spending pressures. Despite its simplicity, the methodology yields projections that compare well with other approaches. It therefore provides a good benchmark for assessing alternative reform scenarios, particularly in data-constrained countries.

Growth Inclusiveness in Djibouti
Description: The paper examines the poverty-reducing and distributional characteristics of Djibouti’s economic growth, and discusses policies that might help make growth more inclusive. It covers the period between 2002 and 2013, for which comparable household surveys are available. The main findings are that while in the past decade the overall level of poverty in Djibouti declined, there have been no clear signs of improvements in either equality or growth inclusiveness. Growth has not been inclusive and benefitted mainly those in the upper part of the income distribution. These conclusions should be treated as indicative. Progress in poverty reduction and inclusiveness would require not only sustained high growth but also the creation of opportunities in sectors with high earning potential for the poor. Better targeted social policies and more attention to the regional distribution of spending would also help reduce poverty and improve inclusiveness.

Late to the game? Capital flows to the Western Balkans
Description: The boom and bust in capital flows to the New Member States of the European Union have received a considerable amount of attention; foreign direct investment and bank flows to the region and countries’ participation in regional supply chains have been well-documented. Relatively little has, however, been written about capital flows to the Western Balkans economies, which are often perceived to be ‘late arrivals’ to large capital flows. This paper aims to examine how capital flows to the Western Balkans compare with flows to the New Member States, in terms of levels as well as dynamics. We find that while financial integration took off somewhat later in the Western Balkans than in the New Member States, it has increased rapidly, despite still much lower capital account openness. Capital inflows as a share of GDP are comparable to those observed in the New Member States, (perhaps surprisingly) diverse in terms of source countries and broadly similar in composition, though with equity shares higher than they were in the New Member States at comparable levels of GDP per capita.

Thick vs. Thin-Skinned: Technology, News, and Financial Market Reaction
Description: We study the impact of technology on the reaction of financial markets to information, focusing on the foreign exchange market. We contrast the “thin-skinned” view that technological improvements cause markets to react more to new information with the “thick-skinned” view that they react less. We pinpoint exogenous technological changes using the timing of the connection of countries via the submarine fiber-optic cables used for electronic trading. Cable connections dampen the response of exchange rates to macroeconomic news, consistent with the “thick-skinned” hypothesis. This is in line with the view that technology eases access to information and reduces trend-following behavior. According to our estimates, cable connections reduce the reaction of exchange rates to U.S. monetary policy news by 50 to 80 percent.

Challenges in Correspondent Banking in the Small States of the Pacific
Description: Access to financial services in the small states of the Pacific is being eroded. Weaknesses in Anti-Money Laundering and Combating the Financing of Terrorism compliance in the context of high levels of remittances are contributing to banks’ decisions to withdraw corresponding banking relationships and close bank accounts of money transfer operators. In this paper, we gather evidence on these developments in the small states of the Pacific, discuss the main drivers, and the potentially negative impact on the financial sector and macroeconomy. We then identify the collective efforts needed to address the consequences of withdrawal of corresponding banking relationships and outline policy measures to help the affected countries mitigate the impact.

Tax Administration Reforms in the Caribbean: Challenges, Achievements, and Next Steps
Description: Over the past decade, governments in the Caribbean region have introduced the value-added tax (VAT) to modernize their tax system, rapidly mobilize revenue and reduce budget deficits. This paper analyzes VAT performance in the region and concludes that while it has boosted revenues, the VAT has not reached its potential. Intended as a broad-based tax with limited exemptions, a single rate and zero-rating confined to exports, the VAT’s design often lacks these characteristics. The paper also finds that although tax administration reforms can boost revenues, countries have just started to address organizational inefficiencies, data integrity issues, and operational ineffectiveness. These reforms need to intensify in order to have a more significant impact on compliance and revenue.
