FLEXIBILITY IN AGRICULTURE

This paper considers the determinants of two dimensions of flexibility, the flexibility in adjusting aggregate output over time ("tactical flexibility") as well as the ability to switch quickly between products ("operational flexibility"). Econometric analysis of a sample of 40,000 farms in Upper-Austria for the period 1980 to 1990 suggests that larger full-time farms operated by younger, better educated farm operators are more flexible, ceteris paribus. The results further indicate a significant and negative interrelationship between tactical and operational flexibility.Farm Management, Industrial Organization,

Do Cooperatives Offer High Quality Products?

The present paper investigates the free-riding problem in determining product quality within cooperatives in a vertically related market. Whereas the individual member has to bear all costs associated with higher quality, the benefits of delivering higher quality have to be shared among all members. On the basis of a Mixed-Oligopoly model, we show that the free-rider problem in the supply of high-quality products, although important for the members of the cooperative, may not be strong enough to ensure that firms will always supply higher quality than cooperatives. Whether the cooperative can overcome the free-riding problem and supply a final product of high quality is shown to depend on the consumer's valuation of quality, the costs of producing high quality, the way in which the quality of the final product is determined from the quality levels of the inputs delivered as well as on the number of members of the cooperative.Agribusiness,

Determinants and Dynamics of Farm Diversification

This paper examines the impact of various farm and household characteristics (such as farm size, the off-farm employment status, the farm operator's age and schooling and the number of family members) on the level as well as the dynamics of on-farm diversification. Using linked census data for Upper-Austria from 1980, 1985 and 1990 we provide evidence that smaller farms are more specialised and also tend to increase the degree of specialisation over time more quickly than large farms. A significantly lower degree of diversification (higher degree of specialisation) as well as a stronger reduction in diversification over time is also reported for businesses operated by older, less educated, part-time farm operators. The analysis of diversification dynamics also suggests that (a) farms adjust to changes in their environment by steadily approaching their long-run equilibrium level of diversification (b-convergence), and (b) the variance of the diversification distribution declines over time (s-convergence). --

On flexibility

By building on theoretical work by Mills and Schumann (1985) and Ungern-Sternberg (1990) this paper provides evidence on the determinants of two dimensions of flexibility, the flexibility in adjusting aggregate output over time (tactical flexibility) as well as the ability to switch quickly between products (operational flexibility). Econometric analysis of a sample of 40.000 farms in Upper-Austria for the period 1980 to 1990 suggests that larger full-time farms operated by younger, better educated farm operators are more flexible, ceteris paribus. The results further indicate a significant and negative interrelationship between tactical and operational flexibility. --tactical and operational flexibility,panel data,farm households

Buyer Power and Product Innovation: Empirical Evidence from the German Food Sector.

Substantial increases in retail concentration (particularly in Europe) raise concerns about the welfare implications for consumers. In a formal model, we argue that retailer market power reduces upstream firms incentives to introduce new products. On the basis of a survey of firms in German food manufacturing, the results of a negative binomial regression model supports the proposition of a detrimental effect of retailer market power on product innovations. This effect is mitigated if manufacturing firms also have some market power (countervailing power). Innovations are positively related to firm?s market share in food manufacturing. --Retailer market power,product innovation,food manufacturing

Variatio Delectat Consumer Demand for Food Diversity

Whereas a large number of empirical studies have been devoted to analysing consumer demand for specific products, much less attention has been paid to the household?s demand for product variety (the number of different products consumed in a specific time period). This paper analyses consumer demand for food variety in Germany. The econometric analysis of 4.632 household in 1995 suggests, that variety increases with income and the number of children aged between 6 and 18 years and is significantly higher if the family lives in larger cities in East-Germany, and the housekeeping person is not additionally working full-time. A single male household consumes a significantly smaller number of different food products. The significant (and positive) impact of household income on food variety is in line with the hypothesis that consumption evolves along a hierarchical order as income increases. --

Farm Structure and the Effects of Agri-Environmental Programs: Results from a Matching Analysis for European Countries

This paper extends previous research (Pufahl and Weiss, 2009) and applies a semi-parametric propensity score matching approach to evaluate the effects of agrienvironment (AE) programs on input use and farm output of individual farms in eight Member States of the European Union. We find substantial differences in treatment effects between countries. The analysis reveals significant effects of AE participation on production (Germany, France) and farm profits (France, Ireland, United Kingdom). AE participation sporadically reduces the intensity of land use as measured by the purchase of farm chemicals (fertilizer, pesticide) and grazing livestock densities. We also find differences in the treatment effect among farms with different farm size (heterogeneous treatment effects).evaluation, agri-environment programs, propensity score matching, Germany, Italy, Spain, France, Portugal, United Kingdom, The Netherlands, EU-15, Agribusiness, Agricultural and Food Policy,

Evaluating the Effects of Farm Programs: Results from Propensity Score Matching

The paper applies a non-parametric propensity score matching approach to evaluate the effects of two types of farm programs (agri-environment (AE) programs and the less favoured area (LFA) scheme) on input use and farm output of individual farms in Germany. The analysis reveals a positive and significant treatment effect of the LFA scheme for farm sales and the area under cultivation. Participants in AE schemes are found to significantly increase the area under cultivation (in particular grassland), resulting in a decrease of livestock densities. Furthermore, participation in AE programs significantly reduced the purchase of farm chemicals (fertilizer, pesticide). We also find substantial differences in the treatment effect between individual farms (heterogeneous treatment effects). Farms which can generate the largest benefit from the program are most likely to participate.evaluation, farm programs, propensity score matching, Agricultural and Food Policy,

Buyer Power and Innovation of Quality Products: Empirical Evidence from the German Food Sector.

The last couple of decades have seen an increased retail concentration around the world, particularly in Europe. Views on the welfare implications of this severe change are controversial. Consumers might benefit because larger stores (owned by larger retailer chains) offer more product choices. On the other hand, there is concern that buyer power may force manufacturers ?to reduce investment in new products or product improvements? [1]. This paper?s aim is to analyse whether retailer power affects food manufacturing firms incentives to invest in innovation of high quality food products. On the basis of a formal model, we find that retailer market power reduces upstream firms incentives to introduce new products. This proposition is tested empirically on the basis of firm level data from a survey of food manufacturing firms carried out in 2002 in Germany. Results of multinomial logit model show a moderate and negative impact of retailer market power on innovation of regular quality products. No such negative impact is observed for premium quality products. Producers of premium products thus seem to more effectively resist retailer market power in product innovation --Retailer market power,innovation,product quality,multinomial logit model
