The Effect of Capital Flows Composition on Output Volatility
(World Bank, Washington, DC, 2013-03)A large literature has argued that different types of capital flows have different consequences for macroeconomic stability. By distinguishing between foreign direct investment and portfolio and other investments, this paper studies the effects of the composition of capital inflows on output volatility. The paper develops a simple empirical model which, under certain conditions that hold in the data, yields three key testable implications. First, output volatility should depend positively on the volatilities of both foreign direct investment and portfolio and other inflows. Second, output volatility should be an increasing function of the correlation between both kinds of inflows. Third, output volatility should be a decreasing function of the share of foreign direct investment in total capital inflows, for low values of that share. The data provide strong support for all three implications, even after controlling for other factors that may influence output volatility, and after dealing with potential endogeneity problems. These findings call attention to the importance of taking into account the synchronization and composition of capital flows for output stabilization purposes, as opposed to just focusing on the volatility of each component of capital flows. -

Reserve Requirements in the Brave New Macroprudential World
(World Bank, Washington, DC, 2014-02)Using a new, large data set on quarterly reserve requirements for the period 1970-2011, this paper provides new evidence on the use of reserve requirements as a countercyclical macroprudential tool in developing countries. The appeal of reserve requirements lies in the pro-cyclical behavior of the exchange rate over the business cycle in developing countries. This enormously complicates the use of interest rates as a countercyclical instrument (because of its effect on the exchange rate) and calls for a second instrument. The paper suggests that conflicts may arise between the microprudential and macroprudential policy stances. -

Reserve Requirements in the Brave New Macroprudential World
(Washington, DC: World Bank, 2014-04-02)In the aftermath of the global financial crisis, it is hard to find any macroeconomic policy report that does not include some reference to financial stability or systemic risk and the resulting need for “macroprudential policies.” While there is a large and growing literature on macroprudential policies and financial stability, less attention has been paid to how macroprudential policies may facilitate macroeconomic stabilization in the presence of large capital flows. To fill such a gap, this report looks at the use of reserve requirements (RR) as a macroprudential tool. Its findings should be of particular interest to emerging market economists and policymakers that are faced with difficult questions regarding how to cope effectively with volatile capital flows. The analysis builds upon a new dataset on quarterly RR covering a large number of industrial and developing countries for the period 1970-2011. It finds that while no industrial country has resorted to active RR policy since 2004, almost half of developing countries have. Indeed, together with interest rates adjustments and forex interventions, RR seem to be an important component of a trio of policy instruments that developing countries have relied upon to navigate through the boom-bust cycles driven by capital flows. The ultimate reason for resorting to RR lies essentially on the procyclical behavior of the exchange rate over the business cycle in developing countries (with the currency depreciating in bad times and appreciating in good times) that complicates enormously the use of interest rates as a countercyclical instrument. Under such circumstances, RR are an effective instrument that can be used countercyclically when concerns about the effects of interest rates on the exchange rate become paramount. Finally, the report suggests that while, from a macroprudential point of view, the most common macroprudential instruments are equivalent, from a microprudential one they are not. Conflicts may thus arise between the micro- and macro-prudential policy stances. In addition, the overall design of macroprudential policies should follow a careful analysis of the role that different financial frictions play in various environments since similar symptoms can reflect very different underlying forces. -

Fiscal Multipliers in Recessions and Expansions : Does It Matter Whether Government Spending Is Increasing or Decreasing?
(World Bank Group, Washington, DC, 2014-07)Using non-linear methods, this paper finds that existing estimates of government spending multipliers in expansion and recession may yield biased results by ignoring whether government spending is increasing or decreasing. For industrial countries, the problem originates in the fact that, contrary to one's priors, it is not always the case that government spending is going up in recessions (i.e., acting countercyclically). In almost as many cases, government spending is actually going down (i.e., acting procyclically). Since the economy does not respond symmetrically to government spending increases or decreases, the "true" long-run multiplier for bad times (and government spending going up) turns out to be 2.3 compared to 1.3 if we just distinguish between recession and expansion. In the case of developing countries, the bias results from the fact that the multiplier for recessions and government spending going down (the "when-it-rains-it-pours" phenomenon) is larger than when government spending is going up. -

From Known Unknowns to Black Swans: How to Manage Risk in Latin America and the Caribbean
(Washington, DC: World Bank, 2018-10-05)After a growth recovery, with an expansion of 1.1 percent in 2017, the region has encountered some bumps in the road. The Latin America and the Caribbean (LAC) region is expected to grow at a modest rate of 0.6 percent in 2018 and 1.6 percent in 2019. This slowdown in the region’s recovery is mainly explained by the crisis that started in Argentina in April, the growth slowdown in Brazil, and the continuing economic, social, and humanitarian collapse in Venezuela. Furthermore, net capital inflows to the region have fallen dramatically since early 2018, bringing once again to the fore the risks faced by LAC. In addition, natural disasters such as earthquakes and hurricanes have brought devastation to the region with disturbing frequency. The core of the report analyzes the foundations of risk, develops a theoretical framework to price risk instruments, and reviews how LAC has managed risk in practice. The overall message of the report is that there are different types of risk: (i) those that follow standard probabilistic distributions that can be easily insured by the market; and (ii) those that exhibit fat-tails (i.e., non-negligible probabilities of extreme events) that are much harder to ensure by the market (like earthquakes). Finally, there are “black swans” that, by definition, are unpredictable events that cannot be insured and force countries to rely exclusively on ex-post aid and/or broad preventive measures. In other words, the fatter are the tails of a distribution, the less market insurance is available, and the more countries will have to rely on ex-post aid. Yet progress in managing risk continues to be made (the Catastrophe Bond for earthquakes in the Pacific Alliance, recently sponsored by the World Bank, being an outstanding example). This would have been unthinkable some time ago. New knowledge and insurance schemes, all supported by institutions such as the World Bank, will undoubtedly make LAC a safer region to live and prosper. -

Effects of the Business Cycle on Social Indicators in Latin America and the Caribbean: When Dreams Meet Reality
(Washington, DC: World Bank, 2019-04-04)After mediocre growth in 2018 of 0.7 percent. LAC is expected to perform only marginally better in 2019 (growth of 0.9 percent) followed by a much more solid growth of 2.1 percent in 2020. LAC will face both internal and external challenges during 2019. On the domestic front. the recession in Argentina; a slower than expected recovery in Brazil from the 2014-2015 recession, anemic growth in Mexico. and the continued deterioration of Venezuela. present the biggest challenges. On the external front. the sharp drop in net capital inflows to the region since early 2018 and the monetary policy normalization in the United States stand among the greatest perils. Furthermore, the recent increase in poverty in Brazil because of the recession points to the large effects that the business cycle may have on poverty. The core of this report argues that social indicators that are very sensitive to the business cycle may yield a highly misleading picture of permanent social gains in the region. -

Policy Implications of Non-linear Effects of Tax Changes on Output
(World Bank, Washington, DC, 2019-01)An earlier paper titled "Non-linear effects of tax changes on output: The role of the initial level of taxation," estimated tax multipliers using (i) a novel dataset on value-added taxes for 51 countries (21 industrial and 30 developing) for the period 1970-2014, and (ii) the so-called narrative approach developed by Romer and Romer (2010) to properly identify exogenous tax changes. The main finding is that, in line with existing theoretical distortionary and disincentive-based arguments, the effect of tax changes on output is highly non-linear. The tax multiplier is essentially zero under relatively low/moderate initial tax rate levels and more negative as the initial tax rate and the size of the change in the tax rate increase. This companion paper first shows that these findings have important policy implications, given that the initial level of taxes varies greatly across countries and thus so will the potential output effect of changing tax rates. The paper then turns to some specific policy applications. It focuses on the relevance of the arguments for revenue mobilization in countries with low levels of provision of public goods and social and infrastructure gaps, as well as in commodity-dependent countries. The paper then considers some practical implications for the standard debt sustainability analysis. Lastly, it evaluates the implications of the findings for the Laffer curve. -

Non-Linear Effects of Tax Changes on Output: The Role of the Initial Level of Taxation
(World Bank, Washington, DC, 2018-12)This paper estimates the effect of worldwide tax changes on output following the narrative approach developed for the United States by Romer and Romer (2010). The analysis uses a novel dataset on value-added taxes for 51 countries (21 industrial and 30 developing) for the period 1970-2014 to identify 96 tax changes. It then uses contemporaneous economic records to classify such changes as endogenous or exogenous to current (or prospective) economic conditions. In line with theoretical distortionary and disincentive-based arguments, and using only exogenous tax changes, the main finding is that the effect of tax changes on output is highly non-linear. The tax multiplier is essentially zero under relatively low/moderate initial tax rate levels and more negative as the initial tax rate and the size of the change in the tax rate increase. Based on a global sample, these novel non-linear findings suggest that the recent consensus pointing to large negative tax multipliers in industrial countries, particularly in Europe (e.g., Alesina, Favero, and Giavazzi, 2015), (i) is not a robust empirical regularity, and (ii) is mainly driven by high initial tax rates in these countries. The paper also shows that the bias introduced by misidentification of tax shocks critically depends on the procyclical or countercyclical nature of endogenous tax changes. The relevance of the arguments is evaluated both for the novel global sample and for Romer and Romer's U.S. dataset. -

How is Tax Policy Conducted over the Business Cycle?
(American Economic Association, 2015-08)It is well known by now that government spending has typically been procyclical in developing economies but acyclical or countercyclical in industrial countries. Little, if any, is known, however, about the cyclical behavior of tax rates (as opposed to tax revenues, which are endogenous to the business cycle and, hence, cannot shed light on the cyclicality of tax policy). We build a novel dataset on tax rates for 62 countries for the period 1960-2013 that comprises corporate income, personal income, and value-added tax rates. We find that tax policy is acyclical in industrial countries but mostly pro cyclical in developing countries. -

Leaning Against the Wind: Fiscal Policy in Latin America and the Caribbean in a Historical Perspective
(World Bank, Washington, DC, 2017-04)This report by the Office of the Chief Economist for Latin America and the Caribbean (LAC) of the World Bank studies the region’s fiscal policies. After reviewing LAC’s growth performance, Chapter 1 provides an accounting of its financing needs during the 21st Century to understand how such a diverse region ended up with fiscal deficits across the board in 2016. Chapter 2 goes back to the 1960s and assesses the cyclical properties of fiscal policies. LAC, like most developing countries and in contrast with most developed economies, exhibited procyclical fiscal policies. Good news arrived in the 2000s: one in three economies became countercyclical, which helped improve credit ratings. Yet fiscal policy is complicated by our inability to know if current economic conditions are temporary or permanent. The report argues for a prudent stance that would err on the side of saving too much during upswings and perhaps borrowing too little during downturns.
