Reward systems based on balanced scorecards typically connect pay to an index, i.e. a weighted sum of multiple performance measures. We show that such an index contract may indeed be optimal if performance measures are non-verifiable so that the contracting parties must rely on self-enforcement....

We study how informal buyer-supplier relationships in the German automotive industry affect procurement. Using unique data from a survey focusing on these, we show that more trust, the belief that the trading partner acts to maintain the mutual relationship, is associated with both higher...

This paper discusses the literature on the enforcement of incomplete contracts. It compares legal enforcement to enforcement via relationships and reputations. A number of mechanisms, such as the repeat purchase mechanism (Klein and Leffler (1981)) and efficiency wages (Shapiro and Stiglitz...

We model non-binding retail-price recommendations (RPRs) as a communication device facilitating coordination in vertical supply relations. Assuming both repeated vertical trade and asymmetric information about production costs, we show that RPRs may be part of a relational contract,...

The literature on public goods has shown that efficient outcomes are impossible if participation constraints have to be respected. This paper addresses the question whether they should be imposed. It asks under what conditions efficiency considerations justify that individuals are forced to pay...

Cultural and institutional differences among nations may result in differences in the ratios of marginal costs of goods in autarchy and thus be the basis of specialization and comparative advantage, as long as these differences are not eliminated by trade. We provide an evolutionary model of...

I show in this paper that incomplete contracts affect a firm's decision about serving foreign customers through exports or local sales from an affiliated plant. When contracts between two agents within a firm are too costly to write, the share of multinational firms may be higher or lower...

We embed a North-South trade model into an incomplete contracts setting where the production of heterogeneous firms can be geographically separated. When a Northern headquarter contracts with a Southern supplier instead of a Northern supplier, the presence of international incomplete contracts...

Can formal contracts help resolving the holdup problem? We address this important question by studying the holdup problem in repeated transactions between a seller and a buyer in which the seller can make relation-specific investments in each period. In contrast to previous findings, we...

This paper studies how social relationships between managers and employees affect relational incentive contracts. To this end we develop a simple dynamic principal-agent model where both players may have feelings of altruism or spite toward each other. The contract may contain two types of...
