Sovereign Rating News and Financial Markets Spillovers: Evidence from the European Debt Crisis

This paper examines the spillover effects of sovereign rating news on European financial markets during the period 2007-2010. Our main finding is that sovereign rating downgrades have statistically and economically significant spillover effects both across countries and financial markets. The sign and magnitude of the spillover effects depend both on the type of announcements, the source country experiencing the downgrade and the rating agency from which the announcements originates. However, we also find evidence that downgrades to near speculative grade ratings for relatively large economies such as Greece have a systematic spillover effects. Rating-based triggers may help explain these results.

Tourism Specialization and Economic Development: Evidence from the Unesco World Heritage List

The present paper investigates whether tourism specialization is a viable strategy for development. We estimate standard growth equations augmented with a variable measuring tourism specialization using instrumental variables techniques for a large cross-section of countries for the period 1980-2002. We introduce an instrument for tourism based on the UNESCO World Heritage List. We find that there is a positive relationship between the extent of tourism specialization and economic growth. An increase of one standard deviation in the share of tourism in exports leads to about 0.5 percentage point in additional annual growth, everything else being constant. Our result holds against a large array of robustness checks.

Do Natural Resources Depress Income Per Capita

Most evidence for the resource curse comes from cross-country growth regressions suffers from a bias originating from the high and ever-evolving volatility in commodity prices. This paper addresses these issues by providing new cross-country empirical evidence for the effect of resources in income per capita. Natural resource dependence (resource exports) has a significant negative effect on income per capita, especially in countries with bad rule of law or bad policies, but these results weaken substantially once we allow for endogeneity. However, the more exogenous measure of resource abundance (stock of natural capital) has a significant negative effect on income per capita even after controlling for geography, rule of law and de facto or de jure trade openness. Furthermore, this effect is more severe for countries that have little de jure trade openness. These results are robust to using alternative measures of institutional quality (expropriation and corruption instead of rule of law).

Commodity Windfalls, Democracy and External Debt

We examine the effects that revenue windfalls from international commodity price booms have on external debt in a panel of 93 countries during the period 1970-2007. Our main finding is that increases in the international prices of exported commodity goods lead to a significant reduction in the level of external debt in democracies, but to no significant reduction in the level of external debt in autocracies. To explain this result, we show that in autocracies commodity windfalls lead to a statistically significant and quantitatively large increase in government expenditures. In democracies on the other hand government expenditures did not increase significantly. We also document that following commodity windfalls the risk of default on external debt decreased in democracies, but increased significantly in autocracies.

Trade policies, institutions and the natural resource curse

We offer new cross-country evidence on the natural resource curse. We investigate the impact of the interaction of natural resource abundance and policies on growth. We find that the resource curse is less severe in countries with less restrictive trade policies and good institutions. However, we show that empirical evidence on the resource curse is not robust to correcting for the endogenous nature of some regressors.

The Composition of Capital Flows; Is South Africa Different?

An ignition system of capacitor discharge type for internal combustion engines having a DC source, an ignition transformer, a thyristor, a capacitor, a transistor and an oscillator. With all the elements in the system, the capacitor is discharged through the thyristor, transistor and primary winding of transformer when the transistor and thyristor are simultaneously rendered conductive in response to the appearance of a pulse from the oscillator. The capacitor is then charged by a counter electromotive force produced in the primary winding of the transformer in response to subsequent cut-off of the transistor.

Resource Windfalls, Macroeconomic Stability and Growth: The Role of Political Institutions

We use a new dataset on non-resource GDP to examine the performance of commodity-exporting countries in terms of macroeconomic stability and economic growth in a panel of up to 129 countries during the period 1970-2007. Our main findings are threefold. First, we find that overall government spending in commodity-exporting countries has been procyclical. Second, we find that resource windfalls initially crowd out non-resource GDP which then increases as a result of the fiscal expansion. Third, we find that in the long run resource windfalls have negative effects on non-resource sector GDP growth. Yet, the effects turn out to be statistically insignificant when controlling for government spending. Both the effects of resource windfalls on macroeconomic stability and economic growth are moderated by the quality of political institutions.

International Commodity Price Shocks, Democracy, and External Debt

We examine the effects that international commodity price shocks have on external debt using panel data for a world sample of 93 countries spanning the period 1970-2007. Our main finding is that positive commodity price shocks lead to a significant reduction in the level of external debt in democracies, but to no significant reduction in the level of external debt in autocracies. To explain this result, we show that positive commodity price shocks lead to a statistically significant and quantitatively large increase in total government expenditures in autocracies. In democracies on the other hand government expenditures did not increase significantly. We also document that following positive windfalls from international commodity price shocks the risk of default on external debt decreased in democracies, but increased significantly in autocracies.

The relative volatility of commodity prices : a reappraisal

This paper studies the volatility of commodity prices on the basis of a large dataset of monthly prices observed in international trade data from the United States over the period 2002 to 2011. The conventional wisdom in academia and policy circles is that primary commodity prices are more volatile than those of manufactured products, although most of the existing evidence does not actually attempt to measure the volatility of prices of individual goods or commodities. The literature tends to focus on trends in the evolution and volatility of ratios of price indexes composed of multiple commodities and products. This approach can be misleading. Indeed, the evidence presented in this paper suggests that on average prices of individual primary commodities are less volatile than those of individual manufactured goods. However, the challenges of managing terms of trade volatility in developing countries with concentrated export baskets remain.

Natural Resources, Volatility, and Inclusive Growth: Perspectives from the Middle East and North Africa

This paper takes stock of the economic performance of resource rich countries in the Middle East and North Africa (MENA) over the past forty years. While those countries have maintained high levels of income per capita, they have performed poorly when going beyond the assessment based on standard income level measures. Resource rich countries in MENA have experienced relatively low and non inclusive economic growth as well as high levels of macroeconomic volatility. Important improvements in health and education have taken place but the quality of the provision of public goods and services remains an important source of concerns. Looking forward we argue that the success of economic reforms in MENA rests on the ability of those countries to invest boldly in building inclusive institutions as well as high levels of human capacity in public administrations.
