A Multi-industry Model of Growth with Financing Constraints
Description: This paper develops a multi-industry growth model in which firms require external funds to conduct productivity-enhancing R&D. The cost of research is industry-specific. The tightness of financing constraints depends on the level of financial development and on industry characteristics. Over time, a financially constrained economy may converge to the growth path of a frictionless economy, so long as an industry with the fastest expanding technological frontier does not permanently fall behind due to low R&D. The model’s industry dynamics map into a differences-in-differences regression, in which industry growth depends on the interaction between financial development and industry level R&D intensity.

Macroeconomic Responses to Terms-of-Trade Shocks: A Framework for Policy Analysis for the Argentine Economy
Description: This paper presents a version of the global integrated monetary fiscal (GIMF) model adapted and calibrated to the Argentine economy. The model replicates the effect of the strong improvement in Argentina's terms of trade stemming from higher world commodity prices as well as other key economic trends in Argentina during the period 2003-2007. The model can be used to assess the potential impact of different combinations of monetary and fiscal policies on output, inflation, and the external trade.

Financial Deepening in the CFA Franc Zone: The Role of Institutions
Description: During the 1980s and early 1990s many Sub-Saharan African (SSA) countries undertook reforms to promote financial sector deepening. Nevertheless, financial sectors in SSA countries remain among the shallowest in the world and, within Sub-Saharan Africa, financial depth in the CFA franc zone is even more limited. This paper sets out to investigate empirically factors that may explain why financial depth in the CFA franc zone is shallower than in the rest of SSA using panel data for a sample of 40 countries for 1992-2006. The results indicate that the gap in financial development between the CFA franc zone countries and the rest of SSA can be explained by differences in institutional quality (e.g., availability of credit information, and strength and enforcement of property rights), variables that policy makers can influence.

Credit Risk Spreads in Local and Foreign Currencies
Description: The paper shows how-in a Merton-type model with bankruptcy-the currency composition of debt changes the risk profile of a company raising a given amount of financing, and thus affects the cost of debt. Foreign currency borrowing is cheaper when the exchange rate is positively correlated with the return on the company's assets, even if the company is not an exporter. Prudential regulations should therefore differentiate among loans depending on the extent to which borrowers have "natural hedges" of their foreign currency exposures.

Estimating Default Frequencies and Macrofinancial Linkages in the Mexican Banking Sector
Description: The credit risk measures we develop in this paper are used to investigate macrofinancial linkages in the Mexican banking system. Domestic and external macro-financial variables are found to be closely associated with banking soundness. At the aggregate level, high external volatility and domestic interest rates are associated with higher expected default probability. Though results vary substantially across individual banks, domestic activity and U.S. growth, and higher asset prices, are generally associated with lower credit risks, while increased volatility worsens credit risks. The expected default probability is also found to be a leading indicator of traditional financial stability indicators.

Madagascar: A Competitiveness and Exchange Rate Assessment
Description: The purpose of this paper is to assess Madagascar's competitiveness in recent years, using both price and nonprice indicators and an exchange rate assessment of the currency. We estimate the distance between the equilibrium and the actual real exchange rates using three methods: the macroeconomic balance approach, the external sustainability approach, and the reduced-form equilibrium real exchange rate approach. These methods suggest that in the medium term the real exchange rate is only slightly overvalued. We also carry out a comparative analysis of nonprice indicators and find that Madagascar performs less favorably than its competitors on structural competitiveness.

Fiscal Stimulus with Spending Reversals
Description: The impact of fiscal stimulus depends not only on short-term tax and spending policies, but also on expectations about offsetting measures in the future. This paper analyzes the effects of an increase in government spending under a plausible debt-stabilizing policy that links current stimulus to a subsequent period of spending restraint. Accounting for such spending reversals brings an otherwise standard new Keynesian model in line with the stylized facts of fiscal transmission, including the crowding-in of consumption and the 'puzzle' of real exchange rate depreciation. Time series evidence for the U.S. supports the empirical relevance of spending reversals.

Financial Spillovers to Emerging Markets During the Global Financial Crisis
Description: In this paper potential financial linkages between liquidity and bank solvency measures in advanced economies and emerging market (EM) bond and stock markets are analyzedduring the latest crisis. A multivariate GARCH model is estimated in order to gauge the extent of co-movements of these financial variables across markets. The findings indicate that the notion of possible de-coupling (in the financial markets) had been misplaced. While EM stock markets reached their peak in the last quarter of 2007, interlinkages between funding stress and equity markets in advanced economies and EM financial indicators were highly correlated and have seen sharp increases during specific crisis moments.

Financial Stress, Downturns, and Recoveries
Description: This paper examines why some financial stress episodes lead to economic downturns. The paper identifies episodes of financial turmoil using a financial stress index (FSI), and proposes an analytical framework to assess the impact of financial stress-in particular banking distress-on the real economy. It concludes that financial turmoil characterized by banking distress is more likely to be associated with severe and protracted downturns than stress mainly in securities or foreign exchange markets. Economies with more arms-length financial systems appear to be particularly vulnerable to sharp contractions, due to the greater procyclicality of leverage in their banking systems.

The Challenge of Reforming Budgetary Institutions in Developing Countries
Description: The paper notes that the development of sound budgetary institutions in countries such as France, the U.K. and the U.S. has taken a very long time?200 years or more?and is still evolving. It discusses Douglass North's prediction?which is supported by available data?that institutional reform is also likely to be very slow in developing countries since the budget is especially prone to rent-seeking influences. Finally, the paper discusses the currently fashionable emphasis on complex, multiannual PFM reform strategies, which have been strongly promoted by the donor community; and advocates a simpler approach grounded on Schick's important principle of "getting the basics right." The paper identifies several areas where further research would be fruitful.
