Using individual travel diary data collected before and after a rail transit expansion in urban Beijing, the impact of urban rail accessibility improvement on the usage of rail transit, automobiles…

The empirical results of the risk-return relationship are mixed for both mature and merging markets. In this paper, we develop a new volatility model to revisit the risk-return relation of the…

Equity concerns have been an important obstacle to adopting congestion pricing, in both developed and developing countries. However, the existing evidence on the equity effects of congestion pricing…

Long memory is an important feature of the volatility of financial returns. We document that the recently developed Realized GARCH model (Hansen et al., 2012) is insufficient for capturing the long…

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…
