Complementarities, Below-Cost Pricing, and Welfare Losses

We analyze below-cost pricing in retail markets and examine its impact on social welfare as well as on suppliers' incentives to invest in quality. Considering negotiations about a linear wholesale price between the retailer and her suppliers, we find that below-cost pricing aggravates the double marginalization problem and causes welfare losses compared to a regime where below-cost pricing is banned. Furthermore, suppliers have stronger incentives to invest in high quality products if a ban of below-cost pricing is enforced.Complementarities, Retailing, Below-Cost Pricing

Quality Standards for Fruits and Vegetables: Help or Hindrance for Rural Development?

Horticulture has developed into one of the most dynamic agricultural sectors in the world. The cultivation of fruits and vegetables has significant potential for increasing agricultural income and reducing rural poverty, particularly in developing and emerging countries. However, it appears that the growing consolidation in the retail sector has shifted power relations along the value-added chain away from producers to retailers. In addition, food retailers rely more and more on their own quality standards. The growing significance of such private standards could help to guarantee the functioning of markets and, ultimately, market access. Yet, it could also increase bilateral dependencies and the risk that producers further up the supply chain are exploited. In turn, this could hinder market access, particularly for small-scale farmers. Public standards offer a reasonable alternative: they create transparency and equal rules for all market participants.Private Standards, Minimum Quality Standards, Rural Development, High-Value Crops

Upfront Payments and Listing Decisions

We analyze the listing decisions of a retailer who may ask her suppliers to make upfront payments in order to be listed. We consider a sequential game with upfront payments being negotiated before short-term delivery contracts. We show that the retailer is more likely to use upfront payments the higher her bargaining power and the higher the number of potential suppliers. Upfront payments tend to lower the number of products offered by the retailer when the products are rather close substitutes. However, upfront payments can increase social welfare if they ameliorate inefficient listing decisions implied by short-term contracts only.Buyer power, upfront payments, retailing

Quality distortions in vertical relations

This paper examines how delivery tariffs and private quality standards are determined in vertical relations that are subject to asymmetric information. We consider an infinitely repeated game where an upstream firm sells a product to a downstream firm. In each period, the firms negotiate a delivery contract comprising the quality of the good as well as a nonlinear tariff. Assuming asymmetric information about the actual quality of the product and focusing on incentive compatible contracts, we show that from the firms' perspective delivery contracts lead to more efficient contracts and thus higher overall profits the lower the firms' outside options, i.e. the higher their mutual dependency. Buyer power driven by a reduced outside option of the upstream firm enhances the efficiency of vertical relations, while buyer power due to an improved outside option of the downstream firm implies less effcient outcomes. --Quality Uncertainty,Private Standards,Vertical Relations,Buyer Power

The Strategic Use of Private Quality Standards in Food Supply Chains

This paper highlights the strategic role retailers private quality standards play in food supply chains. Considering two symmetric downstream firms that are exclusively supplied by a finite number of upstream firms and letting the upstream firms decide which retailer to supply, we show that there exist two asymmetric equilibria in the downstream firms quality requirements. The asymmetry is driven by both an increase in the retailers buyer power and the retailers competition for suppliers. The use of private quality standards induces a decrease in social welfare, which can be softened by the implementation of a public minimum quality standard.Private Quality Standards, Vertical Relations, Buyer Power, Food Supply Chain, Agribusiness, Agricultural and Food Policy, Agricultural Finance, Food Consumption/Nutrition/Food Safety, Industrial Organization,

Consumer Shopping Costs as a Cause of Slotting Fees: A Rent-Shifting Mechanism

Analyzing a sequential bargaining framework with one retailer and two suppliers of substitutable goods, we show that slotting fees may emerge as a result of a rent-shifting mechanism when consumer shopping costs are taken into account. If consumers economize on their shopping costs by bundling their purchases, their buying decision depends rather on the price for the whole shopping basket than on individual product prices. This induces complementarities between the goods offered at a retail outlet. If the complementarity effect resulting from shopping costs dominates the original substitution effect, the wholesale price negotiated with the first supplier is upward distorted in order to shift rent from the second supplier. As long as the first supplier has only little bargaining power, she compensates the retailer for the upward distorted wholesale price by paying a slotting fee. We also show that banning slotting fees causes per- unit price to fall and welfare to increase.Shopping costs, rent-shifting, slotting fees

The Strategic Use of Private Quality Standards in Food Supply Chains

This paper highlights the strategic role that private quality standards play in food supply chains. Considering two symmetric retailers that are exclusively supplied by a finite number of producers and endogenizing the producers' delivery choice, we show that there exist two asymmetric equilibria in the retailers' quality requirements. The asymmetry is driven by both the retailers.incentive to raise their buyer power and the retailers' competition for suppliers. We find that the use of private quality standards is detrimental to social welfare. A public minimum quality standard can remedy this unfavorable welfare outcome.Private quality standards, vertical relations, buyer power, food supply chain
