Growth from International Capital Flows: The Role of Volatility Regimes
Description: Recent commentary has downplayed the growth dividend from international financial integration, highlighting the possibly negative correlation between capital inflows and long-run growth. This paper presents new evidence consistent with standard economic theory and a more benign interpretation of cross-border private capital flows. The key observation is that a country’s growth volatility changes over time. With volatility below a threshold, an inflow of foreign capital has promoted growth. However, during periods of volatile growth, more flows have been associated with slower growth. Volatility levels and changes reflect an interaction of domestic production and institutional structures with global factors.

Financial Cycles: What? How? When?
Description: This paper provides a comprehensive analysis of financial cycles using a large database covering 21 advanced countries over the period 1960:1-2007:4. Specifically, we analyze cycles in credit, house prices, and equity prices. We report three main results. First, financial cycles tend to be long and severe, especially those in housing and equity markets. Second, they are highly synchronized within countries, particularly credit and house price cycles. The extent of synchronization of financial cycles across countries is high as well, mainly for credit and equity cycles, and has been increasing over time. Third financial cycles accentuate each other and become magnified, especially during coincident downturns in credit and housing markets. Moreover, globally synchronized downturns tend to be associated with more prolonged and costly episodes, especially for credit and equity cycles. We discuss how these findings can guide future research on various aspects of financial market developments.

“An Analysis of U.S. Fiscal and Generational Imbalances: Who Will Pay and How?”
Description: This paper updates existing measures of the U.S. fiscal gap to include federal laws up to and including the mid-December 2010 federal fiscal stimulus. It then applies the methodology of generational accounting to establish how the burden of adjustment required to attain fiscal sustainability is shared across generations. We find that the U.S. fiscal and generational imbalances are large under plausible parametric assumptions, and, while not much affected by the financial crisis, they have not improved much by the passing of the Final Healthcare Legislation. We find that, under our baseline scenario, a full elimination of the fiscal and generational imbalances would require all taxes to go up and all transfers to be cut immediately and permanently by 35 percent. A delay in the adjustment makes it more costly.

Fiscal sustainability and the fiscal reaction function for South Africa
Description: How does the South African government react to changes in its debt position? In investigating the question, this paper estimates fiscal reaction functions using various methods (OLS, VAR, TAR, GMM, State-Space modelling and VECM). The paper finds that since 1946 the South African government has ran a sustainable fiscal policy, by reducing the primary deficit or increasing the surplus in response to rising debt. Looking ahead, the paper considers the use of fiscal reaction functions to forecast the debt/GDP ratio and gauging the likelihood of achieving policy goals with the aid of probabilistic simulations and fan charts.

Food Prices and Political Instability
Description: We examine the effects that variations in the international food prices have on democracy and intra-state conflict using panel data for over 120 countries during the period 1970-2007. Our main finding is that in Low Income Countries increases in the international food prices lead to a significant deterioration of democratic institutions and a significant increase in the incidence of anti-government demonstrations, riots, and civil conflict. In the High Income Countries variations in the international food prices have no significant effects on democratic institutions and measures of intra-state conflict. Our empirical results point to a significant externality of variations in international food prices on Low Income Countries' social and political stability.

Modeling Inflation in Chad
Description: This paper examines the determinants of inflation in Chad using quarterly data from 1983:Q1 to 2009:Q3. The analysis is based on a single-equation model, completed by a structural vector auto regression model to capture inflation persistence. The results show that the main determinants of inflation in Chad are rainfall, foreign prices, exchange rate movements, and public spending. The effects of rainfall shocks and changes in foreign prices on inflation persist during six quarters. Changes in public spending and the nominal exchange rate affect inflation during three and four quarters, respectively.

Fiscal Rules in a Volatile World: A Welfare-Based Approach
Description: It is widely agreed that a fiscal rule should boost discipline and credibility, reduce macroeconomic volatility, and be easily understood. To support such goals, a government may run structural surpluses and accumulate a precautionary cushion of assets on behalf of agents who do not enjoy access to capital markets. As an additional criterion, that level of assets should be bounded. We provide an example of a structural surplus rule that satisfies all such criteria. In our general equilibrium simulations, we show that such a rule benefits credit-constrained consumers but may hurt others.

Determinants of Bank Credit in Emerging Market Economies
Description: We examine changes in bank credit across a wide range of emerging market economies during the last decade. The rich time-series and cross-section information allows us to draw broader lessons compared to many existing researches, which focus on a specific set of emerging market economies or on shorter time periods. Our results show that domestic and foreign funding contribute positively and symmetrically to credit growth. The results also indicate that stronger economic growth leads to higher credit growth, and high inflation, while increasing nominal credit, is detrimental to real credit growth. We also find that loose monetary conditions, either domestic or global, result in more credit, and that the health of the banking sector also matters. Finally, we discuss some policy lessons.

Dollarization in Cambodia: Causes and Policy Implications
Description: Over the past decade, Cambodia has become Asia’s most dollarized economy. In contrast, dollarization in neighboring Lao P.D.R., Mongolia, and Vietnam has been either declining or broadly stable. Somewhat paradoxically, growing dollarization in Cambodia has occurred against the backdrop of greater macroeconomic and political stability. The usual motive, currency substitution, does not appear to have been a factor. As the volume of dollars increased over the years, so has the volume of riel. A strong inward flow of dollars related to garments sector exports, tourism receipts, foreign direct investment, and aid, has benefitted the dollar based urban economy. The riel based rural economy has, however, lagged behind. Given international experience in de-dollarization, a carefully managed market based strategy, supported by a continued stable macroeconomic environment is essential for Cambodia’s de-dollarization.

Additions to Market Indices and the Comovement of Stock Returns Around the World
Description: Using newly-constructed data covering the last decade, we document that, in most of forty markets, when added to the main index, firms’ returns experience an increase in comovement with the rest of the index, reflected in higher beta and greater explanatory power of the market return. Stock turnover and analyst coverage also typically increase upon inclusion. Using various tests, we find the demand-based view of comovement (the category/habitat theories of Barberis, Shleifer and Wurgler, 2005) to provide a good explanation for many of our findings. Some results, though, suggest that information-related factors are also important in explaining the increased comovement.
