Bayesian and frequentist criteria fundamentally differ, but often posterior sampling distributions agree asymptotically. For the corresponding single-draw experiment, we characterize size of a certain hypothesis test (possibly nonlinear) inequalities. If null is that parameter lies in specified half-space, then test’s equals α; if subset above otherwise, may be equal to, above, or below α. Reje...

This paper presents an analysis of technical efficiency and technology gap ratio (TGR) in greenhouse cucumber in Fars Province, Iran. Cucumber production was chosen for this study for the reason that greenhouse productions in this provincemainly have focused on this product. The data used in this study was obtained from a random sample of 127 greenhouses in Fars Province for 2010 to 2011. Metaf...

The present study aims to estimate the marginal cost of potable water supply and analyse implications for more efficient, equitable income-adequate tap tariffs in Tunisia. Furthermore, this article develop a new pricing model water. Pricing by Tunisian utility focuses on setting prices cover average costs, often using designs that increase clogging rates. This results large volume being wasted....

This paper explores empirical linkages between credit unions’ (CUs’) policies and their financial perfomance, as measured by loan delinquency and profitability, using a unique micro dataset of credit unions in three Latin American countries. The estimated translog profit function is generalized using a slack variable concept that parameterizes any systematic deviation from profitmaximizing beha...

To prevent further increases in energy consumption, the government of Iran commenced energy subsidy reform in 2010. This paper investigates the fuel conservation effects of the reform in Iran using a homothetic translog cost function that provides estimates of the own- and cross-price elasticities of fuel demands. The percentage reduction in fuel demands is estimated using the likely effect of ...

This paper is concerned with the estimation of total factor productivity (TFP) growth for the Iranian electric utilities during the period 1980-1993 on the basis of panel data. A translog cost function is used which accommodates firm - specific variability through a one - way error component model. The results show that the Iranian electricity supply industry experienced increasing returns to s...

in this study the trend of technological change and its nature was studied in production of sugar beet in iran by using dual approach. this approach is useful for estimating the demand structure of the input price change and technology status. after estimating the various forms of flexible functions, by selection of translog cost function with cost share equations system is estimated using seem...
