We introduce the realized exponential GARCH model that can use multiple realized volatility measures for the modeling of a return series. The model specifies the dynamic properties of both returns and…

Using province-level yield data and daily weather data from 1980 to 2012, we investigated the responses of early rice, middle-season rice, and late rice yields to weather variations in China. In…

We use a mathematical programming model to examine the impacts of simultaneous implementation of two US biofuel and bioenergy policies on commodity markets and spatial distribution of future…

We developed a mathematical programming model to estimate the supply of cellulosic biomass in Illinois at various biomass prices and examine the implications of biomass production for the maintenance…

Using a mathematical programming model, we estimate the economic potential of biomass supply from crop residues in China at various exogenously-given biomass prices and identify the areas that are…

Using a unique county-level panel on single-season paddy rice yield and daily weather outcomes from 1996 to 2009, we examined the impacts of weather variations on paddy rice yield in China. We have…

Congestion plays a central role in urban and transportation economics. Existing estimates of congestion costs rely on stated or revealed preferences studies. We explore a complementary measure of…

The idea for this book first originated in 2012 when writing a paper for a workshop for the University of Dar es Salaam Mwalimu Nyerere Chair on Development. More recently, it has been driven by the…

This paper seeks to examine how communities value a variety of dryland environmental amenities provided by the Kgalagadi Transfontier Park where there is an interest in limiting their access, both in…

This paper demonstrates the importance of wildlife in the portfolio of environmental income in the livelihoods of poor rural communities living adjacent to a national park. The results show that…
