We theoretically and empirically examine the relationship between natural resource revenues and financial development.  In the theoretical part, we present a politico-economic model in which contract enforcement is low and decreasing in resource revenues when political institutions are poor,...

A large literature describes how local risk sharing networks can help individuals smooth consumption in the face of idiosyncratic economic shocks.  However, when an entire community faces a large covariate shock, and when the transaction costs of transfers are high, these risk sharing networks...

We study price competition between firms over public list or posted prices when a fraction of consumers (termed 'bargainers') can subsequently receive discounts with some probability.  Such stochastic discounts are a feature of markets in which some consumers bargain explicitly; of markets in...

We study the accuracy of a wide variety of estimators of asset price variation constructed from high-frequency data (so-called "realized measures"), and compare them with a simple "realized variance" (RV) estimator.  In total, we consider almost 400 different estimators, applied to 11 years of...

In this paper, we study the impact of labor market restructuring and foreign direct investment on the banking sector, using a dynamic general equilibrium model with a financial sector.  Numerical simulations are performed using stylized Chinese data, and banks failures are generated through...

In the vast majority of low-income countries, financing and political constraints have traditionally impaired the usefulness of fiscal policy as a short-run stabilization device. Indeed, it is widely recognized that fiscal policy in such countries has very often tended to be pro-cyclical. While...

Estimating the covariance and correlation between assets using high frequency data is challenging due to market microstructure effects and Epps effects.  In this paper we extend Xiu's univariate QML approach to the multivariate case, carrying out inference as if the observations arise from an...

This paper examines a test for the null of cointegration in a multivariate system based on the discrepancy between the OLS estimator of the full set of n cointegrating relationships in the n + k system and the OLS estimator of the corresponding relationships among first differences without...

The labour productivity differentials between manufacturing firms in Ghana and South Korea exceed those implied by macro analysis.  Median value-added per employee is nearly 40 times higher in South Korea than Ghana.  The most important single factor in explaining this difference is the...

We develop a new methodology for quantifying the tasks undertaken within occupations using 3,000 verbs from around 12,000 occupational descriptions in the Dictionary of Occupational Titles (DOTs).  Using micro-data from the United States from 1880-2000, we find an increase in the employment...
