Serial Sovereign Defaults and Debt Restructurings
Description: Emerging countries that have defaulted on their debt repayment obligations in the past are more likely to default again in the future than are non-defaulters even with the same external debt-to-GDP ratio. These countries actually have repeated defaults or restructurings in short periods. This paper explains these stylized facts within a dynamic stochastic general equilibrium framework by explicitly modeling renegotiations between a defaulting country and its creditors. The quantitative analysis of the model reveals that the equilibrium probability of default for a given debt-to-GDP level is weakly increasing with the number of past defaults. The model also accords with an additional fact: lower recovery rates (high NPV haircuts) are associated with increases in spreads at renegotiation.

Natural Disasters and Food Crises in Low-Income Countries: Macroeconomic Dimensions
Description: The exposure of low-income countries to natural disasters has a significant impact on food production and food security. This paper provides a framework for assessing a country’s vulnerability to food crisis in the event of natural disasters. The paper finds that macroeconomic and structural indicators that are crucial for ensuring the resilience of low-income countries to adverse external shocks are equally important for minimizing the occurrence of food crisis in the event of natural disasters.

Bank Solvency and Funding Cost
Description: Understanding the interaction between bank solvency and funding cost is a crucial pre-requisite for stress-testing. In this paper we study the sensitivity of bank funding cost to solvency measures while controlling for various other measures of bank fundamentals. The analysis includes two measures of bank funding cost: (a) average funding cost and (b) interbank funding cost as a proxy of wholesale funding cost. The main findings are: (1) Solvency is negatively and significantly related to measures of funding cost, but the effect is small in magnitude. (2) On average, the relationship is stronger for interbank funding cost than for average funding cost. (3) During periods of stress interbank funding cost is more sensitive to solvency than in normal times. Finally, (4) the relationship between funding cost and solvency appears to be non-linear, with higher sensitivity of funding cost at lower levels of solvency.

China's Slowdown and Global Financial Market Volatility: Is World Growth Losing Out?
Description: China's GDP growth slowdown and a surge in global financial market volatility could both adversely affect an already weak global economic recovery. To quantify the global macroeconomic consequences of these shocks, we employ a GVAR model estimated for 26 countries/regions over the period 1981Q1 to 2013Q1. Our results indicate that (i) a one percent permanent negative GDP shock in China (equivalent to a one-off one percent growth shock) could have significant global macroeconomic repercussions, with world growth reducing by 0.23 percentage points in the short-run; and (ii) a surge in global financial market volatility could translate into a fall in world economic growth of around 0.29 percentage points, but it could also have negative short-run impacts on global equity markets, oil prices and long-term interest rates.

When Do Structural Reforms Work? On the Role of the Business Cycle and Macroeconomic Policies
Description: Structural reforms are expected to lift growth and employment, but their effects are surprisingly difficult to pin down empirically. One reason is their potential endogeneity to the economic environment in which they are conducted. For example, the impact of a reform implemented shortly before a cyclical upswing is difficult to distinguish from the recovery itself. Similarly, macroeconomic policies conducted along a structural reform could affect the estimated impact. Exploring various options, this paper develops robust estimates of the impact of labor and product market reforms by using local projection techniques while controlling for endogeneity of reforms and other biases. The results suggest that labor and product market reforms have a lagged but positive impact on employment creation, and the positive effect remains even after controlling for the endogeneity of the decision to reform. Supportive macroeconomic policies are found to increase the effect of labor and product market reforms, consistent with the view that some structural reforms are best initiated in conjunction with supportive fiscal or monetary policy.

Winning the Oil Lottery: The Impact of Natural Resource Extraction on Growth
Description: This paper provides evidence of the causal impact of oil discoveries on development. Novel data on the drilling of 20,000 oil wells in Brazil allows us to exploit a quasi-experiment: Municipalities where oil was discovered constitute the treatment group, while municipalities with drilling but no discovery are the control group. The results show that oil discoveries significantly increase per capita GDP and urbanization. We find positive spillovers to non-oil sectors, specifically, an increase in services GDP which stems from higher output per worker. The results are consistent with greater local demand for non-tradable services driven by highly paid oil workers.

Can Government Demand Stimulate Private Investment? Evidence from U.S. Federal Procurement
Description: We study the effects of federal purchases on firms’ investment using a novel panel dataset that combines federal procurement contracts in the United States with key financial firm-level information. We find that 1 dollar of federal spending increases firms’ capital investment by 7 to 11 cents. The average effect masks heterogeneity: Effects are stronger for firms that face financing constraints and they are close to 0 for unconstrained firms. In line with the financial accelerator model, our findings indicate that the effect of government purchases works through easing firms’ access to external borrowing. Furthermore, industry-level analysis suggests that that the increase in investment at the firm level translates into an industry-wide effect without crowding-out capital investment of other firms in the same industry.

Stochastic Trends, Debt Sustainability and Fiscal Policy
Description: We study empirically the reaction of fiscal policy to changes in the permanent and transitory components of GDP in a panel of countries. We find evidence that government spending tends to be counter-cyclical conditional on temporary shocks and pro-cyclical conditional on permanent shocks. We also find no evidence that developing countries are systematically different from developed ones in terms of fiscal policy. We present a theory featuring a fiscal reaction function to the output gap and a measure of debt sustainability. The fiscal impulse response to a permanent (temporary) shock to GDP is positive (negative) as the effect on debt sustainability (current output gap) dominates. The results are mostly sensitive to the relative weight of debt sustainability in the fiscal reaction function as well as to the extent of real rigidities in the economy.

Unconventional Policy Instruments in the New Keynesian Model
Description: This paper analyzes the use of unconventional policy instruments in New Keynesian setups in which the ‘divine coincidence’ breaks down. The paper discusses the role of a second instrument and its coordination with conventional interest rate policy, and presents theoretical results on equilibrium determinacy, the inflation bias, the stabilization bias, and the optimal central banker’s preferences when both instruments are available. We show that the use of an unconventional instrument can help reduce the zone of equilibrium indeterminacy and the volatility of the economy. However, in some circumstances, committing not to use the second instrument may be welfare improving (a result akin to Rogoff (1985a) example of counterproductive coordination). We further show that the optimal central banker should be both aggressive against inflation, and interventionist in using the unconventional policy instrument. As long as price setting depends on expectations about the future, there are gains from establishing credibility by using any instrument that affects these expectations.

Dynamic Connectedness of Asian Equity Markets
Description: Understanding how markets are connected and shocks are transmitted is an important issue for policymakers and market participants. In this paper, we examine the connectedness of Asian equity markets within the region and vis-à-vis other major global markets. Using time-varying connectedness measures, we address the following questions: (1) How has connectedness in asset returns and volatilities changed over time? Do markets become more connected during crises periods? (2) Which markets are major sources and major recipients of shocks? Has there been a shift in terms of the net shock givers and shock receivers (directional connectedness over time)? Finally, we investigate the connectedness between China’s equity markets and other countries’ equity markets since August 2015 to highlight the growing importance of emerging market economies, particularly China, as sources of shocks.
