The notion of indirect separability is exploited to derive a new multistage demand system. The model allows a consistent parameterization of demand relations at various budgeting stages and it fulfills the requirement of flexibility while satisfying separability globally. Two propositions are derived to characterize flexible and separable functional forms, which lead to the specification of a f...

How large are the gains from trade? Do all trade models have the ‘same old gains’? Arkolakis, Costinot, and Rodriguez-Clare (2012) show that many quantitative trade models that summarize trade responses via a single elasticity have the same welfare implications. I develop a flexible approach to estimating trade responses using a translog expenditure function, and find welfare results that diffe...

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 objective of this paper is to estimate the Transcendental Logarithmic Production Function of manufacturing industry in Jordanian economy. Manufacturing industry can be considered as the fourth large one in Jordanian economy. In last decade, the growth rate in this sector is the second one after transport and communications. The gross fixed capital formation in manufacturing is the third one...

Relative prices are nonstationary and standard root-T inference is invalid for demand systems. But demand systems are nonlinear functions of relative prices, and standard methods for dealing with nonstationarity in linear models cannot be used. Demand system residuals are also frequently found to be highly persistent, further complicating estimation and inference. We propose a variant of the tr...

We use the simulation model ofCbalfallt and Gallant (IUS5) to investigate the fit of a Fourier flexible form to a cost function when interest is t.o estimate elasticities of substitution. The data is subject to errors in variables and the estimation method is seemingly unrelated regressions. \IVe use two approximating Fourier functional forms * Hesearch supported by C:-IPq ** Banco do Brasil, C...

The single bootstrap already is popular in economics, though the double bootstrap has better convergence properties. We discuss the theory and implementation of the double bootstrap, both with and without the pivotal transformation, and give detailed examples of each. One example is a nonlinear double bootstrap of a Cobb-Douglas production function, and explains the use of Gauss-Newton Regressi...

The purpose of this paper is to evaluate the efficiency of the East German economy at the firm level using an unbalanced panel over the transition period 1994 to 1998. We adopt a translog stochastic frontier model to estimate technical efficiency in eastern and western Germany. The results indicate that firms in eastern Germany are significantly less efficient than firms in western Germany. The...
