The credit reporting system plays an important role in a credit economy, alleviating information asymmetry and reducing transaction costs. This article reviews the historical developments and…

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…

Abstract: In this paper, we examine the relative influence of individual decisions on joint household decisions, and whether and to what extent joint choices are more or less patient than individual…

This paper develops a stochastic dynamic programming model to investigate a type of dynamic enforcement strategy where the penalties for violations of environmental regulations are based on not only…
