世界経済・社会統計 = World development indicators

Offering a unifying theoretical perspective not readily available in any other text, this innovative guide to econometrics uses simple geometrical arguments to develop students' intuitive understanding of basic and advanced topics, emphasizing throughout the practical applications of modern theory and nonlinear techniques of estimation. One theme of the text is the use of artificial regressions for estimation, reference, and specification testing of nonlinear models, including diagnostic tests for parameter constancy, serial correlation, heteroscedasticity, and other types of mis-specification. Explaining how estimates can be obtained and tests can be carried out, the authors go beyond a mere algebraic description to one that can be easily translated into the commands of a standard econometric software package. Covering an unprecedented range of problems with a consistent emphasis on those that arise in applied work, this accessible and coherent guide to the most vital topics in econometrics today is indispensable for advanced students of econometrics and students of statistics interested in regression and related topics. It will also suit practising econometricians who want to update their skills. Flexibly designed to accommodate a variety of course levels, it offers both complete coverage of the basic material and separate chapters on areas of specialized interest.

Estimation and Inference in Econometrics

We study economic growth and inflation at different levels of government and external debt. Our analysis is based on new data on forty-four countries spanning about two hundred years. The dataset incorporates over 3,700 annual observations covering a wide range of political systems, institutions, exchange rate arrangements, and historic circumstances. Our main findings are: First, the relationship between government debt and real GDP growth is weak for debt/GDP ratios below a threshold of 90 percent of GDP. Above 90 percent, median growth rates fall by one percent, and average growth falls considerably more. We find that the threshold for public debt is similar in advanced and emerging economies. Second, emerging markets face lower thresholds for external debt (public and private)--which is usually denominated in a foreign currency. When external debt reaches 60 percent of GDP, annual growth declines by about two percent; for higher levels, growth rates are roughly cut in half. Third, there is no apparent contemporaneous link between inflation and public debt levels for the advanced countries as a group (some countries, such as the United States, have experienced higher inflation when debt/GDP is high.) The story is entirely different for emerging markets, where inflation rises sharply as debt increases.

Growth in a time of debt

Commodity prices and banking crises

The empirical literature is largely supportive of the importance of financial constraints and identifies local banking development and relationship lending as possible determinants of firms’ propensity to innovate. In this chapter, we argue that the spatial organization of banking systems and the distance of local branches from banks’ decisional centers are major factors influencing the effectiveness in collecting and processing soft information on local innovative firms. We provide evidence showing that, while branch density and the length of credit relationships have a positive causal effect on innovation when considered singularly, after controlling for the functional distance between the banking system and the local economy they lose statistical significance in favor of the latter. In this perspective, our results suggest that the geographical organization of banks and the spatial distribution of their headquarters represent key variables for local development.

Geographical organization of banking systems and innovation diffusion

This paper investigates the relationship between external debt and economic growth in poor countries. The adverse effects of external debt on economic performance are due to the crowding out of public investment and to the disincentive effects, because of debt overhang and uncertainty. Notwithstanding a general agreement on theory, empirical evidence is not conclusive and lacks of robustness. This contribution aims to shed more light on the relationship between external debt and economic growth and to draw some policy implication for debt relief. This work highlights the critical role of econometric and methodological issues. The results for a panel of 152 developing countries over the period 1977-2002 support a negative linear relationship between external debt and economic growth, and between debt service and investment. These effects are found to be stronger in the Low-Income Countries than in the overall sample, raising concern about the dramatic effect that debt has on economic performance in the world's poorest countries. In LICs, a debt reduction from a debt-to-exports ratio of 300 to the HIPC threshold of 150 is estimated to add more than one percentage point to per capita GDP growth, and a debt service reduction is found to be more than two times more effective than an equal increase in foreign aid. Eventually, external debt impairs economic growth through the liquidity constraint, the creation of macroeconomic instability, the lower efficiency of investment, and its effect on macroeconomic policies and institutional development.

The Debt-Growth Nexus: a Dynamic Panel Data Estimation

The potential consequences of the development of domestic debt markets in Low-Income Countries (LICs) are extremely relevant for policy-makers and international financial institutions, especially in light of a scaling-up of public investment in infrastructures. This paper introduces a new dataset on the stock of domestic debt in LICs over the period 1970-2010. With respect to the existing dataset, this one expands the country and time coverage, devotes a careful attention to the problem of the zeros and addresses some inconsistencies between the existing datasets. The descriptive analysis of the evolution of domestic debt in LICs, especially over the last two decades, points out some interesting patterns. The reliance on internal financing has partially offset the reduction in external debt granted by bilateral and multilateral debt relief initiatives. Domestic debt increased at a lower and less volatile pace in countries with better policies and institutions. This pattern is mirrored by a greater capital accumulation, a faster financial development, and a stronger output growth. This descriptive evidence supports the hypothesis that the development of the domestic debt market can bring benefits only in presence of a stable macroeconomic environment, lack of political uncertainty and a developed financial system.

Domestic debt in Low-Income Countries

Standards measures of female ownership and management of firms included in the World Bank Enterprise Survey do not support the existence of a gender gap in access to finance in the Latin American and Caribbean region. Nonetheless, more precise measures show that women-led businesses are more likely to be financially constrained than other comparable firms. The evidence presented herein suggests that this gender gap may be driven by taste-based discrimination. This paper exploits a rich dataset that provides detailed information about female ownership and management in firms, allowing for further understanding of gender gaps in access to finance.
