For individual countries, variable trade barriers can be used to reduce the volatility of domestic relative to world prices. If this is done by countries accounting for a large share of the market, its effect is offset by increases in world price volatility. This study shows the nature of the...

This paper has two purposes. It first considers the impact on world food prices of the changes in restrictions on trade in staple foods during the 2008 world food price crisis. Those changes—reductions in import protection or increases in export restraints—were meant to partially insulate...

This paper uses detailed information on the latitude and longitude of conflict events in Sub-Saharan African countries to study the impact of external income shocks on the likelihood of violence. We consider a number of external demand shocks faced by the countries or the regions within...

This paper investigates the effects of ethnic violence on export-oriented firms and their workers. Following the disputed 2007 Kenyan presidential election, export volumes of flower firms affected by the ensuing violence dropped by 38 percent and worker absence exceeded 50 percent. Large firms...

U.S. retail food price increases in recent years may seem large in nominal terms, but after adjusting for inflation have been quite modest even after the change in U.S. biofuel policies in 2006. In contrast, increases in the real prices of corn, soybeans, wheat and rice received by U.S. farmers...

A large literature suggests that standard exchange rate models cannot outperform a random walk forecast and that the forward rate is not an optimal predictor of the spot rate. There is evidence, however, that the term structure of forward premia contains valuable information for forecasting...

In this article, we demonstrate that a small degree of stochastic variation in the depreciation rate of capital can greatly reduce the comovement between hours worked and labour productivity in a neoclassical growth model. The depreciation rate is modeled as a Markov process to place a strict...

This paper examines the experience of 14 developed countries for which there are about 30 years of quarterly inflation-adjusted housing price data. Price dynamics is modelled as a combination of a country-specific component and a cyclical component. The cyclical component is a two-state Markov...

We examine the relationship between interest rates of different maturities for the US, Germany and Japan over the period 1982-2000, using a general, multivariate vector equilibrium correction modelling framework capable of simultaneously allowing for asymmetric adjustment and regime shifts. This...

We propose to use the attractiveness of pooling relatively short time series that display similar dynamics, but without restricting to pooling all into one group. We suggest estimating the appropriate grouping of time series simultaneously along with the group-specific model parameters. We cast...
