We study how the information and communications technology (ICT) ecosystem affects the sustainable growth of ICT firms. For our study, we analyze the efficiencies of ICT firms in China, South Korea, the United States, and Japan, which are the current leaders in the global ICT industry, each with different ICT ecosystem structures. We use metafrontier analysis (MFA) to compare the efficiencies a...

The role of criminal, social interactions occupies a central place in criminology, yet minimal research exists on the relationship between co-offender networks and dimensions of offending. Drawing on the social network literature, this investigation hypothesizes that a link exists between the level of redundancy (i.e., the extent of overlap) in an individual’s co-offender network and offending ...

This paper reports a study regarding households’ willingness to pay for private sector solid waste management services. The data originated from a contingent valuation survey conducted in 224 households in Ilorin in southwest Nigeria and was analysed using tobit and censored least absolute deviations models. The use of a robust and consistent estimator to model zero willingness to pay responses...

This study investigates the various influence models of nodes' network centrality in the context of transactional community. Combining the Social Network Analysis (SNA) with Tobit regression, the research indicates that: i) a node's degree centrality (its followers) and betweenness centrality (the number of the shortest paths in which the node is included) have a positive impact on its network ...

treatments with respect to PFS were estimated through a survival analysis of patient-level data (Celgene data on file). Due to the potential of crossover/subsequent treatment options induced bias, OS was estimated using a quantitative relationship between PFS and OS from a censored normal weighted Tobit regression model, based on 153 MM studies containing 230 treatment arms7. In this study, Fél...

In this article we consider the estimation of two seemingly unrelated Tobit regressions in which the dependent variables are truncated normal. The model is useful, since it can be viewed as the reduced form of a simultaneous-equations Tobit model. The proposed estimation method and algorithm are interesting in themselves for the following reasons. In the estimation of a simultaneous equations m...

This research aims to analyze each of the operational and financial factors that can be used as variables influencing decisions intensity hedging. There are two test analysis model in this study, first company decision hedge a measured by using dummy second is hedging ratio derivative natural logarithm derivative. By Probit Tobit regression, results logistic regression show such distress, lever...
