HERE WE PRESENT the likelihood function used to estimate the parameters of the demand model. The model can be thought of as a system of four “standard” equations: (i) a tobit down payment equation (with censoring at the minimum down), (ii) a probit purchase equation, (iii) a tobit repayment equation (with censoring at full payment or at the end of our sample), and (iv) a linear price negotiatio...

140f 2 The aim of this study is to analyze the level of environmental, economic, and social engagement disclosed by local governments, taking into account factors such as political ideology and media pressure. We analyzed 102 large Spanish municipalities, using data from 2011. An econometric model is used based on dependency techniques for cross-sectional data. The Tobit technique is suitable, ...

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...

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 ...

This study focuses on a comparison and evaluation of models and estimators appropriate for time-use data. The tobit type I as well as different generalizations are used. According to our findings, a simple tobit I method can produce results that are similar and in some cases even better to the much more sophisticated methods. This is especially true if the participation or index equation is inc...
