More Competitive Than You Think? Pricing and Location of Processing Firms in Agricultural Markets

The spatial distribution of production is a defining characteristic of agriculture, and the location choice in geographic space and the spatial pricing policies adopted by agricultural processing/packing firms are key determinants of the competitiveness and efficiency of agricultural product procurement markets. Spatially distributed buying firms in the presence of costly transportation of farm products creates natural oligopsony procurement markets. Although several studies have contributed to our understanding of price and output determination and the distribution of welfare in these markets, all are limited in that they address buying firms' locations or their choices of spatial pricing strategy in isolation, holding the other factor fixed, even though both would be chosen jointly in reality to comprise a firm's product-procurement strategy. Here we overcome this limitation by using computational methods (including genetic algorithms) to study duopsony firms' joint choices of location and pricing policy. Our results differ considerably from those presented in prior literature. In general, we find that, when buyers have the flexibility to jointly choose their locations and pricing strategies, market outcomes are much more competitive and locations more efficient in terms of cost minimization than has been predicted by prior studies viewing location choice or pricing strategy in isolation.

The Proliferation of Credence-Attribute Products in the Food Supply Chain and the Challenges of Adequately Feeding a Growing World Population in the 21^st Century

Credence attributes are product characteristics that cannot be discerned directly by consumers either through search or experience and must be certified in a credible way. This presentation will assess the implications of the rapidly rising market shares for foods with credence attributes that involve claims regarding animal welfare, fairness of marketing arrangements, and environmental benefits, among others. Most credence attributes are associated with lower yields than conventional alternatives, resulting in higher food costs and uncertain environmental implications. Proliferation of credence-attribute goods adds to challenges we face as a global society in producing enough food to feed an expanding and wealthier world community at reasonable cost. Credence-attribute products appeal mainly to wealthier consumers, meaning policies to support their expansion are also regressive.
