Resource Windfalls and Emerging Market Sovereign Bond Spreads: The Role of Political Institutions
Description: We examine the effect that revenue windfalls from international commodity price shocks have on sovereign bond spreads using panel data for 30 emerging market economies during the period 1997-2007. Our main finding is that positive commodity price shocks lead to a significant reduction in the sovereign bond spread in democracies, but to a significant increase in the spread in autocracies. To explain our finding we show that, consistent with the political economy literature on the resource curse, revenue windfalls from international commodity price shocks significantly increased real per capita GDP growth in democracies, while in autocracies GDP per capita growth decreased.

Consensus Forecasts and Inefficient Information Aggregation
Description: Consensus forecasts are inefficient, over-weighting older information already in the public domain at the expense of new private information, when individual forecasters have different information sets. Using a cross-country panel of growth forecasts and new methodological insights, this paper finds that: consensus forecasts are inefficient as predicted; this is not due to individual forecaster irrationality; forecasters appear unaware of this inefficiency; and a simple adjustment reduces forecast errors by 5 percent. Similar results are found using US nominal GDP forecasts. The paper also discusses the result’s implications for users of forecaster surveys and for the literature on information aggregation.

Sudden Stops, Output Drops, and Credit Collapses
Description: This paper proposes a tractable Sudden Stop model to explain the main patterns in firm level data in a sample of Southeast Asian firms during the Asian crisis. The model, which features trend shocks and financial frictions, is able to generate the main patterns observed in the sample during and following the Asian crisis, including the ensuing credit-less recovery, which are also patterns broadly shared by most Sudden Stop episodes as documented in Calvo et al. (2006). The model also proposes a novel explanation as to why small firms experience steeper declines than their larger peers as documented in this paper. This size effect is generated under the assumption that small firms are growth firms, to which there is support in the data. Trend shocks when combined with financial frictions in this model also generate strong leverage effects in line with what is observed in the sample, and with other observations from the literature.

Public Debt and Growth
Description: This paper explores the impact of high public debt on long-run economic growth. The analysis, based on a panel of advanced and emerging economies over almost four decades, takes into account a broad range of determinants of growth as well as various estimation issues including reverse causality and endogeneity. In addition, threshold effects, nonlinearities, and differences between advanced and emerging market economies are examined. The empirical results suggest an inverse relationship between initial debt and subsequent growth, controlling for other determinants of growth: on average, a 10 percentage point increase in the initial debt-to-GDP ratio is associated with a slowdown in annual real per capita GDP growth of around 0.2 percentage points per year, with the impact being somewhat smaller in advanced economies. There is some evidence of nonlinearity with higher levels of initial debt having a proportionately larger negative effect on subsequent growth. Analysis of the components of growth suggests that the adverse effect largely reflects a slowdown in labor productivity growth mainly due to reduced investment and slower growth of capital stock.

Exchange Rate Assessment for Sub-Saharan Economies
Description: This paper provides an exchange rate assessment for sub-Saharan African economies by using methodologies similar to those developed by the International Monetary Fund’s Consultative Group on Exchange Rate Issues. As in the World Economic Outlook (IMF, 2009a), the unbalanced panel dataset covers 182 countries from 1973 to 2014. We apply four methodologies to assess the fundamental exchange rate: macroeconomic balance, equilibrium real exchange rate, external sustainability, and purchasing power parity. Results show that the impact of macroeconomic fundamentals on the equilibrium real exchange rate is different for sub-Saharan African economies than for advanced and less advanced economies.

Inflation and Conflict in Iraq: The Economics of Shortages Revisited
Description: Containing inflation has turned out to be one of the most challenging aspects of economic management in Iraq. This paper posits that conventional as well as unconventional factors explain inflation dynamics in the recent past. We build a theoretical model based on the insights into the workings of socialist economies under supply shortages provided by Shleifer and Vishny (1992) to help explain price dynamics. In the model, strategic behavior of the fuel distribution monopolist results in fuel shortages, with implications for fuel and non-fuel inflation. A number of step-wise adjustments of administered prices for fuel products since December 2005 offer an interesting experiment to help study this behavior. Our findings show that inflation may have been influenced by shortages in fuel and non-fuel commodity supplies, which themselves are driven by violence and rent-seeking.

The Impact of Capital and Foreign Exchange Flowson the Competitiveness of Developing Countries
Description: Attracting capital and foreign exchange flows is crucial for developing countries. Yet, these flows could lead to real exchange rate appreciation and may thus have detrimental effects on competitiveness, jeopardizing exports and growth. This paper investigates this dilemma by comparing the impact of six types of capital and foreign exchange flows on real exchange rate behavior in a sample of 57 developing countries covering Africa, Europe, Asia, Latin America, and the Middle East. The results reveal that portfolio investments, foreign borrowing, aid, and income lead to real exchange rate appreciation, while remittances have disparate effects across regions. Foreign direct investments have no effect on the real exchange rate, contributing to resolve the above dilemma.

Subnational Health Spending and Soft Budget Constraints in OECD Countries
Description: Government spending on health has grown as a percent of GDP over the last 40 years in industrialized countries. Widespread decentralization of healthcare systems has often accompanied this increase in spending. In this paper, we explore the effect of soft budget constraints on subnational health spending in a sample of OECD countries. We find countries where subnational governments rely primarily on central government financing and enjoy large borrowing autonomy have higher healthcare spending than those with more restrictions on subnational government borrowing.

Fire Sales and the Financial Accelerator
Description: During periods of financial turmoil, increases in risk lead to higher default, foreclosure, and fire sales. This paper introduces a costly liquidation process for foreclosed collateral and endogenous recovery rates in a dynamic stochastic general equilibrium model of the financial accelerator. Consistent with empirical evidence, we find that recovery rates are pro-cyclical when collateral is costly to liquidate. Through links between recovery rates, risk premia, and default risk, the model generates an additional liquidity spiral, a feedback loop for the financial accelerator. We illustrate how collateral liquidation and monetary policy alter the impacts of a financial shock. We also show that a government subsidy on collateral liquidity and the endogenous accumulation of liquidity inventory help dampen the liquidity spiral by shoring up recovery rates.

FDI Flows to Low-Income Countries: Global Drivers and Growth Implications
Description: What accounts for variations in FDI flows from advanced to developing countries? How have FDI inflows explained cross-country growth experiences? In this paper we tackle both these questions empirically for a large sample of middle and low-income countries. Two key results emerge: (i) lower borrowing costs and positive real-side external factors were increasingly important drivers of FDI outflows to low-income countries in the pre-crisis period; (ii) economic fundamentals, the strength of economic reforms, and commitment to macroeconomic discipline are crucial determinants of the growth dividends of FDI. Our paper suggests that low-income countries can turn to domestic policy solutions to mitigate the adverse effects of a potential decline in FDI in the post-crisis world.
