Repetitive values of the ranking indicators of economic welfare are often introduced due to incidental ties or censoring in the welfare variable, or the categorical nature of welfare variables used in numerous national surveys. In calculating concentration index (CI), assigning different...

Objective Recent studies indicate continuing health disparities across geographic units in the US. This paper provides updated estimates of the association between socioeconomic factors and population health using a new state-level dataset and panel econometric methods that account for...

We show that an equity pairs trading strategy generates large and significant abnormal returns. We find that two components of the trading signal (short term reversal and pairs momentum) have different dynamic and cross-sectional properties. The pairs momentum is largely explained by the one...

This research evaluated forecasting accuracy of hedonic price models based on a number of different submarket assumptions. Using home sale data for the City of Knoxville and vicinities merged with geographic information, we found that forecasting housing prices with submarkets defined using...

This paper utilizes a unique county-level dataset to examine technical efficiency and technology gap in China's agriculture. We classify the counties into four regions with distinctive levels of economic development, and hence production technologies. A meta-frontier analysis is used. We find...

Heien and Wessells' two-step estimator for the multivariate sample-selection model has been used extensively during the past 15 years. A modified version of it, with slightly different selectivity regressors, has also appeared in the empirical literature. Both estimators are unfounded and...

The experiments of reforming the methane of coke-oven gas with steam were performed. The effects of the thermodynamic factors, such as the H2O/CH4 ratio, the conversion temperature (T) of methane and the reaction time (t), on the methane conversion rate have been investigated. The experimental...

Three types of market segmentation strategies are available to estimate hedonic housing price models—i.e. no segmentation, segmentation by using statistical clustering methods and segmentation by using a priori information. This research tests the hypothesis of Tiebout theory that...
