Using the between-sector variation in income as a new measure of economic uncertainty, this paper proposes simple models and supportive empirical evidence for the causal relations between economic uncertainty and government size in the open economy setting. Key empirical findings include: (1) a...

The analysis in this paper suggests that import and export volume elasticities are markedly lower in oil-exporting Middle East and Central Asian countries than in non-oil countries in the region. A key implication of this finding is that a real appreciation of the exchange rate in oil-exporting...

Studies of the impact of trade openness on growth are based either on cross-country analysis-which lacks transparency-or case studies-which lack statistical rigor. We apply transparent econometric methods drawn from the treatment evaluation literature to make the comparison between treated...

In this paper, we assess the macroeconomic determinants of stock market capitalization in a panel of 17 countries in the Middle East and Central Asia, including both hydrocarbon-rich countries and economies without sizeable natural resource wealth. In addition to traditional variables, we...

This paper develops a new index which provides early warning signals of a growth crisis in the event of large external shocks in low-income countries. Multivariate regression analysis and a univariate signaling approach are used to map information from a parsimonious set of underlying policy,...

This paper examines the impact of financial depth on macroeconomic volatility using a dynamic panel analysis for 110 advanced and developing countries. We find that financial depth plays a significant role in dampening the volatility of output, consumption, and investment growth, but only up to...

This paper develops a cost-benefit approach that helps to quantify the optimal level of international reserves in low-income countries, focusing on the role of reserves in preventing and mitigating absorption drops triggered by large external shocks. The approach is applied to a sample of 49...

We examine the cyclical properties of development aid using bilateral data for 22 donors and over 100 recipients during 1970?2005. We find that bilateral aid flows are on average procyclical with respect to business cycles in donor and recipient countries. However, they become countercyclical...

In many developing countries, a significant part of economic activity takes place in the informal sector. Earlier work has examined the determinants of the size of the informal sector, focusing separately on factors such as tax and regulation burden, financial market development, and the quality...

This paper develops a dynamic computable general equilibrium model in which optimizing agents evade taxes by operating in the underground economy. The cost to firms of evading taxes is that they find themselves subject to credit rationing from banks. Our model simulations show that in the...
