This paper examines the factors affecting the participation of farm households in farm land rental markets with particular focus on the impact of the land reform. The operational outcomes of such market participation are also analysed. The study used a panel dataset of farm households surveyed before and after the land reform with Random Effect Tobit model. The analysis showed that the land ref...

Based on the literature on the diffusion of innovations and on information systems, and building on emerging concepts in electronic collaboration (e-collaboration), this article measures the influence of various determinants on manufacturing firms’ intent to use Web-based inter-organizational information systems (IOISs) to share inventory information with their key suppliers. This theoretical m...

This paper uses Data Envelopment Analysis to measure scale and technical efficiencies of 925 farms in rural Colombia and a Tobit model to identify the effects of land market characteristics on efficiency. Findings indicate that although larger farms are more scale efficient, they are not more technical efficient than small farms. Participation in land markets increases technical efficiency, ind...

This paper aims to evaluate the operating efficiency of e-market for exploring the efficiency-oriented critical drivers on the development of e-market. A hybrid approach consisting of data envelopment analysis (DEA) and bootstrapped Tobit regression analysis is adopted. The efficiency of forty-three emarkets is investigated with respect to their respective overall efficiency, technical efficien...

This paper develops a new method to solve multivariate discrete-continuous problems and applies the model to measure the influence of residential density on households’ vehicle fuel efficiency and usage choices. Traditional discrete-continuous modelling of vehicle holding choice and vehicle usage becomes unwieldy with large numbers of vehicles and vehicle categories. I propose a more flexible m...

We propose a new model for analyzing the length of hospital stay when variances are heterogeneous. This model is an alternative to the conventional models such as Cox’s proportional hazard model and can be used to address various problems of survival analysis. The model is a heteroskedastic version of the Box–Cox transformation model and is estimated by the tobit maximum likelihood method, and ...

Concerns about the safe use of clinical ultrasound (US) at diagnostic pressure levels (below a mechanical index, or MI, = 1.9) have stimulated considerable research in US risk assessment. The objective of the present study was to develop probability-based risk thresholds for US safety studies, to present statistical methods for estimating the thresholds and their standard errors and to compare ...

The standard approaches to estimating minimum variance hedge ratios (MVHRs) are mis-specified when futures prices are subject to price limits. This paper proposes a bivariate tobit-FIGARCH model with maturity effects to estimate dynamic MVHRs using single and multiple period approaches. Simulations and an application to a commodity futures hedge support the proposed approach and highlight the i...
