Current Account Deficits in Africa: Stylized Facts and Basic Determinants

This article analyzes the behavior of current account deficits in Africa. The findings are that deficits are (i) not very persistent; (ii) positively linked with domestic growth; (iii) strongly linked with public (and private) savings, suggesting that fiscal consolidation in IMF‐supported programs may be relatively effective; (iv) linked with aid flows, so as to close the external gap; and (v) linked with currency depreciation and the terms of trade.

Housing Finance and Mortgage-Backed Securities in Mexico

This paper reviews the Mexican experience with the securitization of residential mortgages. It highlights the key legislative and institutional reforms leading to the development of primary and secondary mortgage markets and reports the main features and valuation practices of the RMBS markets. The paper identifies areas warranting close attention to improve the outlook for the Mexican RMBS market and draws some lessons from the recent U.S. subprime mortgage market problems.

Technological Adaptation, Trade, and Growth

Technological Adaptation, Trade, and Growth. — Based on Grossman and Helpman’s 1991 seminal work, the authors provide a simple model extension where innovations created in the high-tech sector may be assimilated or adapted by the lowtech sector, thus generating nondecreasing returns in the production function of the latter. When applying a Heckscher-Ohlin framework the authors find that the effects of technological diffusion allow a country relatively scarce in human capital to benefit from nondecreasing rates of growth through its low-tech sector. They test this idea by using a dynamic panel data approach in order to deal with simultaneity and country heterogeneity. Their results are consistent with the predictions of the model and robust to a broad range of definitions of technological intensity.

Re-Accessing International Capital Markets After Financial Crises : Some Empirical Evidence

The paper analyzes the factors that contribute to the re-access of countries that emerge from a severe financial crisis to the international capital markets. It conjectures that these factors depend on a sovereigns commitment and ability to repay its foreign debt, signaled by sound macroeconomic policies, and the global liquidity environment. Using panel data for 49 countries over a 24-year period, the analysis uses a simple probit approach to show that, indeed, a sustainable debt profile and a sound external position, accompanied by a favorable global liquidity environment, are key factors in affecting the likelihood a sovereign reaccesses international capital markets.

Market Signals and the Cost of Credit Risk Protection: An Analysis of CDS Settlement Auctions

We study the link between the probability of default implied by Credit Default Swaps (CDS) spreads and the final prices of the defaulted bonds as established at the CDS settlement auctions. We observe that the post-default recovery rates at the observed spreads imply markets were often “surprised” by the credit event. We find that the prices of the bonds that are deliverable at the auctions imply probabilities of default that are systematically different than the default probabilities estimated prior to the event of default using standard methodologies. We discuss the implications for CDS pricing models. We analyze the discrepancy between the actual and theoretical CDS spreads and we find it is significantly associated both to the CDS market microstructure at the time of the settlement auction and to the general macroeconomic background. We discuss the potential for strategic bidding behavior at the CDS settlement auctions.

Technology and Epidemics

Evidence from historical and epidemiological literatures show that epidemics tend to spread in the population according to a logistic pattern. We conjecture that the impact of new technologies on output follows a pattern of spread not unlike that of typical epidemics. After reaching a critical mass, rates of growth will accelerate until the marginal benefits of technology are fully utilized. We estimate spline functions using a GMM dynamic panel methodology for 79 countries. We use imports of machinery and equipment as a fraction of gross domestic product as a proxy for the process of technological adoption. Results confirm our hypothesis.
