All business transactions as well as achieving innovations take up resources, subsumed under the concept of transaction costs. One of the major factors in transaction costs theory is information. Firm networks can catalyse the interpersonal information exchange and hence, increase the access to...

The Constant Elasticity of Substitution (CES) function is popular in several areas of economics, but it is rarely used in econometric analysis because it cannot be estimated by standard linear regression techniques. We discuss several existing approaches and propose a new grid-search approach...

In the estimation of multiple output technologies in a primal approach, the main question is how to handle the multiple outputs. Often an output distance function is used, where the classical approach is to exploit its homogeneity property by selecting one output quantity as the dependent...

The stochastic ray production frontier was developed as an alternative to the traditional output distance function to model production processes with multiple inputs and multiple outputs. Its main advantage over the traditional approach is that it can be used when some output quantities of some...

The study is devoted to the comparative static analysis and econometric estimation of farm household decisions under both standard and agricultural taxes. Accounting for labor market constraints a non-separable model is constructed implying increasing per-unit costs of accessing labor markets....

Der Artikel umfasst eine quantitative polit-ökonomische Analyse aktueller und zukünftiger Reformen der Gemeinsamen Europäischen Agrarpolitik unter unterschiedlichen Szenarios einer zukünftigen EU-Osterweiterung und zukünftigen WTO-Verhandlungen. Theoretische Grundlage der Analysen ist ein...

The impact of political institutions, e.g. the organization of legislature, election and party systems, on agricultural protection has hardly been taken into account explicitly in theoretical and empirical studies, yet. In this framework the paper investigates to what extent political...

This paper derives an applied general political economy model incorporating a model of political decision-making into a computable general economic equilibrium model. Political decision-making among a set of legislators is modeled via a mean voter decision rule derived from a modified...
