fast food has become a prominent feature of diet and has grown into a dominant dietary pattern among youth worldwide. it is difficult to escape noticing the colourful edifice and bill boards of these food outlets, one is probably just around the corner of your street. mr biggs, tastes fried chicken, sweet sensation, big treat, favourite etc. due to competitive nature of the market many of the f...

this study investigates issues on efficiency and elasticity of broiler production in peninsular malaysia. data from 296 broiler farms were subjected to sfa, dea and bootstrap methods for technical efficiency; translog and tobit regression analyses to estimate elasticity of production and determinants of efficiency respectively in broiler production. we found that farmers produce mean efficiency...

The Tobit model (censored regression model) is an important basic model appearing in many applications in economics. In this paper we consider a duration Tobit model in which a duration variable which counts the number of times the data is being censored is included as a covariate. We show that in this case, the dependent variable eventually becomes degenerate, which makes the asymptotic Fisher...

In this paper, we use a semi-parametric two-stage model to examine the effect of bankspecific, industry-specific and macroeconomic determinants of bank efficiency. This method, proposed by Simar and Wilson (2007), relaxes several deficiencies of previous two-stage analyses, which regress non-parametric estimates of bank efficiency on exogenous determinants. In particular, we propose a bootstrap...

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...

Contributions to public goods simulated in economists' laboratory experiments have two peculiarities from the perspective of statistical modelling. There is a variety of contributor behaviours (Ledyard, 1995), suggestive perhaps of separate classes of individuals, and contributions are doubly censored. We present an econometric model of contributions in sequential play, which takes into account...

This papjer proposes alternatives to maximum likelihood estimation of the censored and truncated regression models (known to economists as "Tobit" models) . The proposed estimators are based on symmetric censoring or truncation of the upper tail of the distribution of the dependent variable. Unlike methods based on the assumption of identically distributed Gaussian errors/ the estimators are co...
