| We present a general equilibrium model with oligopsonistic market structure in one of the sectors. Buyers of inputs can set the price of inputs by being involved in rent seeking activities. The framework developed is applied to the Bulgarian economy in particular to the agro-food chain. From the application to the Bulgarian economy we find that if there are market imperfections, such as oligopsonistic behavior in the economy, there are no significant welfare gains from free trade. Significant welfare gains from trade are observed only when a competitive structure prevails. We show that eliminating this market imperfection can bring important welfare implications and an efficient reallocation of resources. |

The rates of change exceeding this quasi autonomous component are regressed on explanatory variables. The most significant influence is found for the expected incomes in agriculture, the opportunity costs of family labour and general labour market conditions. Ziel der Analyse ist es, die Bestimmungsgrunde der Bestandsentwicklung landwirtschaftlicher Familienarbeitskrafte in Westdeutschland und deren... |
