A Guide to Sovereign Debt Data
Description: The last decade or so has seen a mushrooming of new sovereign debt databases covering long time spans for several countries. This represents an important breakthrough for economists who have long sought to, but been unable to tackle, first-order questions such as why countries have differential debt tolerance, and how debt levels affect the scope for countercyclical policy in recessions and financial crises. This paper backdrops these recent data efforts, identifying both the key innovations, as well as caveats that users should be aware of. A Directory of existing publicly-available sovereign debt databases, featuring compilations by institutions and individual researchers, is also included.

Financial Openness and Capital Inflows to Emerging Markets: In Search of Robust Evidence
Description: We reassess the connection between capital account openness and capital flows in an empirical framework that is grounded in theory and makes use of previously unexplored variation in the data. We demonstrate how our theory-consistent regressions may overcome some ubiquitous measurement problems in the literature by relying on interaction terms between financial openness and traditional push-pull factors. Within our proposed framework, we ask: what can be said robustly about the effect of capital account restrictions on capital flows? Our results warrant against over-interpreting the existing cross-country evidence as we find very few robust relationships between capital account restrictiveness and various types of capital inflows. Countries with a higher degree of financial openness are more susceptible to some, but by no means all, push and pull factors. Overall, the results are still consistent with a complex set of tradeoffs faced by policymakers, where the ability to shield the domestic economy from volatile capital flow cycles must be weighed against the sources of exogenous risks and potential long run growth effects.

The Inflexible Structure of Global Supply Chains
Description: The rise of global supply chains has had profound effects on individual economies and the global trading system, thereby complicating standard macroeconomic analyses. For many of the new and challenging questions brought about by this phenomenon, such as its impact on the global business cycle and measurements of competitiveness, the answer largely depends on one specific aspect of global value chains: how easily they can re-configure in response to changes in prices. We propose a parsimonious, generalized specification to test the degree of global-supply-chain flexibility. Our estimates show that, in the short run, the production structure is highly inflexible, and that this rigidity has, if anything, risen over time as supply chains have deepened over time. This finding is robust to alternative price measures, including those that account for the U.S. dollar’s outsized role in trade through invoicing. While in the long run all estimated elasticities rise, supply chains remain somewhat inflexible. Our results have implications for analyses of cross-country business-cycle dynamics, the propagation of sectoral shocks, and the measurement of international competitiveness.

The Level REER model in the External Balance Assessment (EBA) Methodology
Description: This paper offers an empirical model of the drivers of the level of the Real Effective Exchange Rate (REER) that is now part of the IMF’s methodology for the assessment of external positions, including exchange rates. It constructs a measure of the level of the REER and it offers a panel regression that considers a large number of cross-sectional and time varying factors, guided by the extensive literature. Its main contribution is to enhance our understanding of the cross-sectional determinants of the level of the REER, while taking into account the time-series drivers. The framework accounts for the much larger cross-sectional variation of the level REER, and can better explain the time series variation of level REER when these are based on GDP-deflators rather than on consumer price indices. The latter suggest there may be merits to broadening the assessments to include such measures, although further analysis is required.

Manufacturing Jobs and Inequality: Why is the U.S. Experience Different?
Description: We examine the extent to which declining manufacturing employment may have contributed to increasing inequality in advanced economies. This contribution is typically small, except in the United States. We explore two possible explanations: the high initial manufacturing wage premium and the high level of income inequality. The manufacturing wage premium declined between the 1980s and the 2000s in the United States, but it does not explain the contemporaneous rise in inequality. Instead, high income inequality played a large role. This is because manufacturing job loss typically implies a move to the service sector, for which the worker is not skilled at first and accepts a low-skill wage. On average, the associated wage cut increases with the overall level of income inequality in the country, conditional on moving down in the wage distribution. Based on a stylized scenario, we calculate that the movement of workers to low-skill service sector jobs can account for about a quarter of the increase in inequality between the 1980s and the 2000s in the United States. Had the U.S. income distribution been more equal, only about one tenth of the actual increase in inequality could have been attributed to the loss of manufacturing jobs, according to our simulations.

Credit Misallocation and Economic Growth in Vietnam
Description: The legacy of non-performing loans and high opportunity cost of government financing of bank recapitalization impeded the efficiency of financial intermediation and are an important policy issue in Vietnam. This paper presents a theoretical and empirical analysis of the issue. An empirical analysis using corporate data indicates credit misallocation between state owned enterprises and private firms in Vietnam. On the theoretical side, a micro-founded banking model is embedded in a political economy setting to assess the factors determining the size of bank recapitalization and its effects on the efficiency of financial intermediation, economic growth and welfare. The analysis suggests that recapitalization depends on an array of factors, including the tightness of the government budget and the decision maker’s concern for the favored sector.

Reallocating Public Spending to Reduce Income Inequality: Can It Work?
Description: Can a government reduce income inequality by changing the composition of public spending while keeping the total level of expenditure fixed? Using newly assembled data on spending composition for 83 countries across all income groups, this paper shows that reallocating spending toward social protection and infrastructure is associated with reduced income inequality, particularly when it is financed through cuts in defense spending. However, the political and security situation matters. The analysis does not find evidence that lowering defense spending to finance infrastructure and social outlays improves income distribution in countries with weak institutions and at higher risk of conflict. Reallocating social protection and infrastructure spending towards other types of spending tends to increase income inequality. Accounting for the long-term impact of health spending, and particularly education spending, helps to better capture the equalizing effects of these expenditures. The paper includes a discussion of the implications of the findings for Indonesia, a major emerging market where income inequality is at the center of policy issues.

Advancing Inclusive Growth in Cambodia
Description: We evaluate the impact of fiscal reforms on growth and inequality in Cambodia using a calibrated general equilibrium model with heterogeneous agents (Peralta-Alva et al., 2018). Over the last two decades, Cambodia’s consumption inequality and poverty have declined. However, income inequality is higher, and large gaps remain between urban and rural residents. At the same time, domestic revenue mobilization has improved substantially, but collection of tax revenue is biased towards non-progressive sources. We use the model to evaluate the growth and inequality impact of reforms that increase infrastructure spending by raising (i) VAT, (ii) property tax, or (iii) personal income tax. We find that using property taxes delivers the largest increase in GDP and reduction in inequality. Reaping the gains from property taxation will however require additional investments in tax administration.

A Possible Approach to Fiscal Rules in Small Islands — Incorporating Natural Disasters and Climate Change
Description: A big challenge for the economic development of small island countries is dealing with external shocks. The Pacific Islands are vulnerable to natural disasters, climate change, commodity price changes, and uncertain donor grants. The question that arises is how should small developing countries formulate a fiscal policy to achieve economic stability and fiscal sustainability when prone to various shocks? We study how natural disasters affect long-term debt dynamics and propose fiscal policy rules that could help insulate the economy from such unexpected shocks. We propose fiscal rules to address these shocks and uncertainties using the example of Papua New Guinea. Our study finds the advantages of expenditure rules, especially a recurrent expenditure rule based on non-resource and non-grant revenue, interdependently determined by government debt and budget balance targets with expected disaster shocks. This paper contributes to the literature and policy dialogue by theoretically analyzing the impact of natural disasters on debt sustainability and proposing fiscal rules against natural disasters and climate changes. Our fiscal policy framework is practically applicable for many developing countries facing increasing frequency and impact of natural disasters and climate change. Our rules-based fiscal framework is crucial for sustainable and countercyclical macroeconomic policies to build resilience against devastating natural hazards.

Macroeconomic and Financial Policies for Climate Change Mitigation: A Review of the Literature
Description: Climate change is one of the greatest challenges of this century. Mitigation requires a large-scale transition to a low-carbon economy. This paper provides an overview of the rapidly growing literature on the role of macroeconomic and financial policy tools in enabling this transition. The literature provides a menu of policy tools for mitigation. A key conclusion is that fiscal tools are first in line and central, but can and may need to be complemented by financial and monetary policy instruments. Some tools and policies raise unanswered questions about policy tool assignment and mandates, which we describe. The literature is scarce, however, on the most effective policy mix and the role of mitigation tools and goals in the overall policy framework.
