Última Explaining differences in farms efficiencies in Polish agriculture AgEcon Hockmann, Heinrich; Pieniadz, Agata. This paper deals with the estimation of a random coefficient model. The virtue of this approach is that it considers firm heterogeneity, which conventional SFA models do not. When the model is applied to Polish farms, the results indicate that the conventional random and fixed effect models overestimate the potential production increases due to the reduction of inefficiency. Additionally, our findings provide evidence of the importance of input quality for efficiency analysis. Moreover, the results indicate that farm heterogeneity is a significant determinant of agricultural production. We found that differences in productivity between the farms can partly be attributed to farm size, degree of integration in the product markets and incurred transaction...

Ano: 2009 URL: http://purl.umn.edu/51051 Agricultural Prices, Selection, and the Evolution of Food Industry AgEcon Gaigne, Carl; Le Mener, Leo. In this paper, we set up a simple model that explains the relation between low input price, high exit rates and industrial oncentration. More precisely, we argue that falling input prices force firms with low productivity to exit and induce expansion of more efficient incumbents at the expense of less productive producers. Our model helps reconcile some well‐established empirical results regarding the food processing industry. Indeed, agricultural prices have been declining between the early 1900s until 2006 while, over the same period, concentration and firm productivity have been increasing in the agri‐food industry.

Ano: 2012 URL: http://purl.umn.edu/125221 Heterogeneous firms and trade costs: a reading of French access to European agro-food market AgEcon Chevassus-Lozza, Emmanuelle; Latouche, Karine. This article offers a new reading of intra-European trade based on recent developments in new international economics (Melitz, 2003; Chaney, 2008). These models take the heterogeneity of firms into account and offer a micro-economic analysis of the process of selection at work for firms entering markets. An exporting firm has to bear certain specific costs to break into a market, and only sufficiently productive firms are able to do so. Using individual data for French agro-food firms and the distribution of their exports across European markets, this article shows that access conditions to the various European markets are not identical for French firms: the Belgian market would seem to be a natural extension of the French market, whereas the markets of...
