This paper identifies the efficiency-oriented critical drivers for e-market using a two-stage approach. The efficiency of twenty-six e-markets is investigated first with respect to their respective overall efficiency, technical efficiency and scale efficiency, leading to the identification of the fully efficient emarkets and the underlying source of inefficiency in the existing e-markets. The e...

Tolulope Olayemi Oyekale Federal University of Agriculture Abeokuta, Ogun State, Nigeria ABSTRACT Poverty reduction is the goal of all rural development programs embarked upon by Nigerian government. This is important because poverty is a critical problem in Nigeria and the rural areas are mostly affected. This study examined the impact of government programs on the multidimensional poverty of ...

The paper investigates price dynamics under market liberalization, with a focus on the effects of lowering price floors. We analyze price dynamics by specifying and estimating a dynamic Tobit model under time-varying volatility, where the market price is censored by a government-set support price. The model is applied to the U.S. butter market over the last three decades. The econometric result...

In this paper I propose a computationally practical simulation estimator for large categories of the dynamic panel Tobit model with complicated dependence structures. I first apply the sequential decomposition methods introduced by Hendry and Richard (1992) to obtain the tractable simulated log-likelihood function of the dynamic panel Tobit model. I then maximize this log-likelihood function si...

The paper investigates the pretrial discovery process empirically. Using data from an interview survey of both attorneys in 369 federal civil cases, and by employing a simultaneous-equations tobit econometric model, I identify factors that determine the plaintiff’s and defendant’s discovery levels. The four main results show that the discovery behaviors of plaintiffs and defendants are differen...

This paper deals with a linear errors-in-variables model where the dependent variable is censored. A two-step procedure is proposed to derive the moment estimator of the model and the corresponding asymptotic covariance matrix. The results cover the moment estimation of the usual (error-free) Tobit model as a special case. It is shown that, under normality and a certain identifying condition, t...

Much of the world’s gene pool is located in tropical rainforests, which are being destroyed at an alarming rate. Proper management of protected forests is crucial to avoid further loss of biodiversity. Resource extraction by local communities can be a major obstacle in the management of protected forests. This paper develops a two sector dynamic model for agriculture and forest resource extract...

We develop a Bayesian method for nonparametric model–based quantile regression. The approach involves flexible Dirichlet process mixture models for the joint distribution of the response and the covariates, with posterior inference for different quantile curves emerging from the conditional response distribution given the covariates. An extension to allow for partially observed responses leads ...
