Productive efficiency analysis is a relevant tool that can be used to evaluate differences in efficiency performance between conventional and organic farms. Such study is important for the assessment of the economic viability of these two agricultural systems. While the existing research has...

In this paper we consider two general approaches to the selection of thresholds in multivariate threshold models. The first criteria ignores the cross equation correlation while the latter explicitly accounts for it. We focus on how model selection may be influenced by these alternative...

Our paper looks at how price volatility in the Brazilian ethanol industry changes over time and across markets. Demand and supply forces in the energy and food markets are likely to ensure that crude oil, ethanol and feedstock prices co-move in the long-run. Hence, when assessing price...

This paper estimates static Malmquist and dynamic Luenberger productivity growth measures and decomposes these to identify the contributions of technical change, technical efficiency change and scale efficiency change. The Malmquist and Luenberger productivity growth measures are estimated using...

A simple but new theoretical approach is used to analyse ex-ante the impact of tariff reduction. This methodology is based on the assumption of a constant price relation between each direct substitutable product. No elasticities are needed, but accurate import and domestic prices of the most...

The paper presents an application of the new version of the 'Decision Support for Irrigated agriculture' DSIrr designed to integrate water and agricultural policy analysis and to support participatory decision process. The tool is a scenario manager for bio-economic farm models considering...

Due to economic and population growth farmland and to a lesser extend other undeveloped areas are under pressure in the urban-rural fringe in British Columbia, Canada. The objectives of this paper are to determine if residential property values near Victoria, BC include open-space premiums for...

The goal of the TOPMARD project is to develop a model of agriculture and rural development to better understand the agronomic, ecological, economic and social dimensions of rural regions. The resulting model, (Policy Model of Multifunctional Agriculture and Rural Development) was built...

Econometric models wishing to estimate relevant parameters for agricultural policy analysis are increasingly relying on unbalanced panels of farm-level data. Since in the agricultural economics literature such models have often been estimated through simplified approaches, in this paper we try...

Micro-econometric models have become a standard and powerful tool in analysing agricultural policies. In this paper we assess the contributions that have been made in the agricultural economics literature to dynamic microeconometric models of firms and households that are estimated using...
