In this article we first develop a theoretically consistent supply-response model for producers with invariant preferences facing price risk, and then we empirically apply the model for a group of Cretan olive-oil producers. For doing so, we estimate a Generalized Leontief cost function and we use the price distribution historically faced by individual farmers to induce three different representations of price risk corresponding to the second, third and fourth lp norms. These risk measures are combined with the estimated cost-structure to provide three separate representations of the efficient frontier for the representative producer.
The present paper studies the relative efficiency between hotels operating under a brand and hotels operating independently, in the island of Crete, Greece, using the Data Envelopment Analysis.
This paper develops a parametric decomposition framework of labor productivity growth relaxing the assumption of labor-specific efficiency.
A theoretical framework is developed for decomposing partial factor productivity and measuring technical inefficiency when the underlying technology is characterized by factor non-substitution.
Using the Lichtenberg-Zilberman-Fox-Weersink damage specification, we develop a short-run, supply-response framework based on rational producer behavior in the presence of damage agents.
In standard consumer demand analysis, it is implicitly assumed that consumers behave optimally and, thus, efficiently. However, optimality is a restrictive assumption to make for consumers’ actual behaviour. This study moves away from this restrictive assumption and develops a theoretical model for the analysis of consumer’s inefficiency in price-quantity space.
This paper studies the problem of a company which expands its stochastic production capacity in irreversible investments by purchasing capital and faces both fixed and proportional costs.
This paper develops a tractable theoretical framework for analyzing the substitutability between different advertising media, the extent of marketing spillovers in the market, the allocative efficiency of advertising spending, and the sources of total advertising productivity and sales growth.
Due to the assumption that the best practice methods refer to each input separately instead of the whole set of inputs used by a firm, the benchmark technology as defined in the stochastic varying coefficient frontier model may be infeasible and theoretically improper whenever the maximum response coefficients are not coming from the same production unit. To overcome this problem we suggest an alternative procedure for measuring output-oriented and input-specific technical efficiency inspired from the maximum likelihood formulation of the non-neutral frontier model.
The present paper incorporates the Cornwell, Sickless and Schmidt (1990) flexible specification of the temporal pattern of technical efficiency into technical inefficiency effects model. The proposed formulation is then applied to the agricultural sector of the EU and US, during the period 1973-1993.
Using a stochastic frontier approach and a tranlog input distance function, this paper implements the input-oriented Malmquist productivity index to a sample of Greek aquaculture farms.
This paper attempts to provide an empirical evaluation of the potential relationship between sectoral linkages and technical efficiency using the 1996 US input-output tables.
This paper proposes a tractable approach for analyzing the sources of TFP changes (i.e., technical change, changes in technical and allocative inefficiency, and the scale effect) in a multi-output setting, while retaining the single-equation nature of the econometric procedure used to estimate the parameters of the underlying technology.
The generalized quadratic Box-Cox transformation is used to test the relative performance of alternative, widely used, functional forms and to examine the effect of prior choice on final efficiency estimates.
This paper provides an empirical comparison of time-varying technical inefficiency measures obtained from the econometric estimation of different specifications of the stochastic production frontier model.
