This paper uses an output oriented Data Envelopment Analysis (DEA) measure of technical efficiency to assess the technical efficiencies of the Brazilian banking system. Four approaches to estimation are compared in order to assess the significance of factors affecting inefficiency. These are nonparametric Analysis of Covariance, maximum likelihood using a family of exponential distributions, ma...

This study assessed the determinants of intensity of improved rice varieties adoption using the Tobit model and also employed. The Heckman Two-stage model was used to identify the determinants of market participation and its potential impact on farming households’ welfare in three states selected from the three notable rice producing ecologies in Nigeria. A crosssectional data of 600 rice farme...

In China, environmental non-governmental organizations (ENGOs) play an important supervisory role to address ecological issues together with government regulation and enterprise implementation. This study examines the effect of ENGO presence on corporate environmental responsibility (CER) performance, along with internal factors as covariate variables. With a sample of 677 enterprises, it opera...

This study uses a sample of 715 banks from 95 countries and two-stage data envelopment analysis (DEA) to provide international evidence on the impact of regulations and supervision approaches on banks’ efficiency. We first use DEA to estimate technical and scale efficiency. We then use Tobit regression to investigate the impact of several regulations related to capital adequacy, private monitor...

Monica Fisher Rural Poverty Research Center, Oregon State University, 221 Ballard Hall, Corvallis, OR 97331; [email protected] Abstract This paper examines the role forests play in alleviating poverty in rural Malawi. Data from three villages in southern Malawi indicate high levels of forest dependence. Gini decomposition shows that access to forest income reduced measured income inequal...

DEA is a statistical procedure used to evaluate the relative efficiency of separable entities, termed “decision-making units” (DMUs), where each DMU converts certain inputs into outputs. The methodology can provides an ordinal ranking compared Pareto-efficient frontier, and widely measure require that weights be explicitly set, which more advantageous than conventional measures efficiency. Tobi...

Tobit models are extended to allow threshold values which depend on individuals’ characteristics. In such models, the parameters are subject to as many inequality constraints as the number of observations, and the maximum likelihood estimation which requires the numerical maximisation of the likelihood is often difficult to be implemented. Using a Bayesian approach, a Gibbs sampler algorithm is...

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 ...

The structure of European banking markets has substantially changed over the past decade, partially as a result of the creation of the Single Internal Market. The process of integration and accompanying deregulation has embodied an incentive for bank management to focus on improving efficiency, especially given the more competitive banking environment. In this paper, employing the non-parametri...
