Traditional measures of the benefits of technological change use producer prices. Consumer-oriented measures are more appropriate but they require knowledge of price impacts. They may diverge in the presence of distortions. This paper shows that in general equilibrium they are interrelated...

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...

In this paper we introduce inverse demand systems that include quadratic scale terms. These systems are similar to regular quadratic demand systems introduced by Howe, Pollack, and Wales. A unique feature of these specifications is that they maintain linear scale curves as a special case. For...

This research develops 'Johansen-type' models of agriculture and constructs Input-Output models for assessing the impact of the post-1992 CAP reforms on incomes, employment and the environment in four Alentejo study areas of Portugal. The effects of agricultural output changes on businesses...

This study provides a dynamic mathematical treatment of price determination under bilateral monopoly. The results are: a) a quantitiative solution for the equilibrium price; b) equality of profits of the buyer and seller; c) dynamically stable equilibrium price; and d) the bargaining process...

In this study a demand system analysis for beef in South Korea is constructed. A free trade demand system was used in which the economic welfare of market participants are maximized. Recognizing implicit discrimination about non-locally sourced beef products, this study deduces market demand...

Micro-econometric demand modelling has been receiving an increasing attention in empirical research, mainly due to the increasing availability of micro-data. In this paper we provide a review of some relevant market and policy issues that can be analysed with the use of micro-data on demand....

This paper provides an opportunity for the reader to get an insight into the current modelling work at the Research Institute for Agricultural Economics, Hungary (AKI). After giving a short summary of the applied econometric models in the past decade, our latest development, the farm group model...

The demand for wine is generally estimated on an aggregate level as a single commodity. However, as recent history shows us, the demand for wine not only varies considerably by varietal, but also by price point within each varietal. As a result, although estimates of the demand for wine may be...
