This study examines the relative technical efficiency of 12 hospitals in Eastern Ethiopia. Using six-year-round panel data for the period between 2007/08 and 2012/13, this study examines the technical efficiency, total factor productivity, and determinants of the technical inefficiency of hospitals. Data envelopment analysis (DEA) and DEA- based Malmquist productivity index used to estimate rel...

One of the difficult challenges facing management and researchers today is how to justify costly investments in information technology (IT). This paper presents an approach to investigating the effects of IT on technical efficiency in a firm’s production process through a two-stage analytical study with a firm-level data set. In the first stage, a nonparametric frontier method of data envelopme...

This paper studies financial behaviors of households in China’s Beijing urban area. Demographic and psychometrical data were collected through questionnaire surveys and analyzed by logistic regression and Tobit regression methods. Several important factors which affect the willingness of the investigated households to participate in investment activities and their portfolio allocation decisions...

Female labor market activity is dependent on the presence and the age of a child, but how do the determinants develop in magnitude and significance with the child’s age? Using German SOEP data from 1991 to 2006 for mothers with young children, the change in maternal labor supply when the child is one, two, and three years old is explicitly addressed. According to the detailed descriptive analys...

Parameters of quantitative genetic models have traditionally been estimated by either algebraic manipulation of familial correlations (or familial mean squares), biometric model fitting, or multiple-group covariance structure analysis. With few exceptions, researchers who have used these methods for the analysis of twin data have assumed that their data were multinormal and, consequently, have ...

It is crucial for social policy in Less Developed Countries to identify separate correlates for transient poverty and chronic poverty at the household level because seasonal poverty substantially contributes to annual poverty. This has been attempted by estimating household equations for those poverty indicators typically by using Tobit and Probit models. However, when errors in household pover...

The study analysed the technical efficiency and technology gap ratio in cocoa production Nigeria. A multistage sampling technique was used to select 390 farmers from three zones where is commercially grown Separate stochastic frontier models were estimated for Kwara, Edo Ondo States, along with a metafrontier model obtain alternative estimates efficiencies of different states. Subsequently, Tobi...

This paper examines the determinants of export performance of firms in the Greek manufacturing industry, using cross-sectional data from 1652 firms in 1999 and a Tobit regression model. The study finds that firms that have larger size, lower unit labor cost and low capital to labor ratio have a higher propensity to export, confirming the fact that in Greece, which has the second lowest capital ...
