The objective of this paper is to analyze the 1999 exchange rate (real/dollar) devaluation impact on coffee and intermediate input prices. Input price increased with exchange rate devaluation, reducing the positive effect of the exchange rate on coffee production, compared with the scenario...

It is intended to verify the relations between input and products concerning to replaceability or complementarity, as well as the impacts of monthly variations on product prices (milk and meat) and input (fuels, work, concentrate) in the production system in Brazil that possess cows of 2.000 to...

The aim of this paper is to estimate an education production function using a survey collected in the public schools of Mendoza. Through the estimation of a translog technology that enables the evaluation of second order effects, the results of the best fitted model recall what is found in the...

We derive a measure of scale efficiency change in the case of a translog output-oriented, multi-input, multi-output distance function without imposing restrictions in previous analogous works by Ray (1998, 1999) and Balk (2001). This may be particularly useful in productivity analysis based on...

Previous studies on hospitals’ efficiency often refer to quite restrictive functional forms for the technology (Aigner et al., 1977, J. Econom., 6, 21–37) . In this paper, referring to a study about some hospitals in Lombardy, we formulate convenient correctives to a statistical model based...
