GARCH-jump models of metal price returns, while allowing for sudden movements (jumps), apply the same specification of the jump component in both 'bear'and 'bull' markets. As a result, the more frequent but relatively small jumps that occur in both bear and bull markets dominate the...

A median voter model is developed to explain the size of the vertical fiscal gap in a federation, i.e. the extent to which subnational governments' expenditures exceed their own-source tax revenues. In our model, individuals vote in subnational elections and in federal elections to determine tax...

We generalize the Boadway and Keen (2006) model of adverse selection in a capital market to allow for risk aversion on the part of entrepreneurs. We show that the Boadway and Keen conclusion-that adverse selection leads to excessive investment-does not necessarily hold when entrepreneurs are...

Regression-based testing techniques has long been used to quantify whether the efficient frontier of a set of assets spans the frontier of a larger collection of investments. This work derives regression-based spanning tests for the case in which the investment possibilities set contains, or is...

It is widely accepted that China needs to shift from its past mode of export-led growth and start to rely more on domestic demand. What role could the real appreciation of the Chinese yuan play in this regard? We attempt to quantify the impact on the structure of the Chinese economy of the real...

Does democracy lead to the creation of too many municipalities? We analyze this issue within the context of the Alesina and Spolare (1996) model where the quality of municipal services deteriorates with the distance from the center of a municipality. Individuals can vote in a referendum to split...

The issue of testing for a unit root allowing for a structural break in the trend function is considered. The focus is on the construction of more powerful tests using the information in relevant multivariate data sets. The proposed test adopts the GLS detrending approach and uses correlated...

We analyze the spatial distribution of genetically modified (GM) and organic crops. Because some organic crops will likely be contaminated by GM crops, not all of the non-GM crops can be sold as organic. Therefore, the choice of producing organic crops will depend on the surrounding crops. When...

Previous research has repeatedly found a puzzling one-time drop in the mean and median of consumption at retirement, contrary to the predictions of the life-cycle hypothesis. However, very little is known as to whether these effects vary across the consumption distribution. This study expands...

Biofuels have received a lot of attention as a substitute for gasoline in transportation. They have also been blamed for recent increases in food prices. Both the United States and the European Union have adopted mandatory blending policies that require a sharp increase in the use of biofuels....
