| Abstract: | Previous work has shown that unobservable random shocks on output have a detrimental effect on effort provision in short-term ('static') employment relationships. Given the prevalence of long-term ('dynamic') relationships in firms, we investigate whether the impact of shocks is similarly pronounced in gift-exchange relationships where the same principal-agent pair interacts repeatedly. In dynamic relationships, shocks have a significantly less pronounced negative effect on the agent's effort provision than in static relationships. In an attempt to identify the drivers for our results we find that the combination of a repeated-game effect and a noise-canceling effect is required to avoid the detrimental effects of unobservable random shocks on effort provision. |

| Abstract: | We analyze competition on nonlinear prices in homogeneous goods markets with consumer search. In equilibrium firms offer two-part tariffs consisting of a linear price and lump-sum fee. The equilibrium production is socially efficient as the linear price of equilibrium two-part tariffs equals to the production marginal cost. Firms thus compete in lump-sum fees, which are dispersed in equilibrium. We show that sellers enjoy higher profit, whereas consumers are worse-off with two-part tariffs than with linear prices. The competition softens because with two-part tariffs firms can make effective per-consumer demand less elastic than the actual demand. |

| Abstract: | Our life is built around coordinating efforts with others. This usually involves incentivizing others to do things, and sustaining our relationship with them. Using the wrong incentives backfires: it lowers effort and tarnishes our relationships. But what constitutes a ‘wrong’ incentive? And can incentives be used to shape relationships in a desired manner? To address these and other questions, we introduce relational incentives theory, which distinguishes between two aspects of incentives: schemes (how the incentive is used) and means (what is used as an incentive). Prior research has focused on means (e.g., monetary vs. non-monetary incentives). Our theory highlights the importance of schemes, with a focus on how they interact with social relationships. It posits that the efficacy of incentives depends largely on whether the scheme fits the relational structure of the persons involved in the activity: participation incentive schemes for communal sharing relations, hierarchy for authority ranking relations, balancing for equality matching relations, and proportional incentive schemes for market pricing relations. We show that these four schemes comprise some of the most prevalent variants of incentives. We then discuss the antecedents and consequences of the use of congruent and incongruent incentive schemes. We argue that congruent incentives can reinforce the relationship. Incongruent incentives disrupt relational motives, which undermines the coordinating relationship and reduces effort. But, importantly, incongruent incentives can also be used intentionally to shift to a new relational model. The theory thus contributes to research on relational models by showing how people constitute and modulate relationships. It adds to the incentives and contracting literatures by offering a framework for analyzing the structural congruence between incentives and relationships, yielding predictions about the effects of incentives across different organizational and individual-level contexts. |

| Abstract: | This paper proposes a general competing mechanism game of incomplete information where a mechanism allows its designer to send a message to himself at the same time agents send messages. This paper introduces a notion of robust equilibrium. If each agent's payoff function is separable with respect to principals' actions, they lead to the full characterization of equilibrium allocations in terms of incentive compatible direct mechanisms without reference to the set of arbitrary mechanisms allowed in the game. Szentes' Critique (Szentes (2010)) on the standard competing mechanism game of complete information is also valid in a model with incomplete information. |

| Abstract: | This chapter presents an overview of advances in the structural analysis of contracting in vertical markets over the past fifteen years. We provide a discussion of theoretical models of contracting and bargaining that form the basis of recent empirical work, and then present common approaches used by researchers to take these models to the data. We also briefly survey the structural empirical literature on topics in vertical markets (including horizontal and vertical mergers, price discrimination, and nonlinear and exclusionary contracts), and conclude with a discussion of potential topics for future research. |

| Abstract: | One of the factors that discourages farmers from enrolling in agro-environmental schemes (AES) is the uncertainty of the costs and benefits associated with the adoption of the new practices. In this study, we distinguish between the "internal uncertainty" that is related to the characteristics of the farmer and his/her parcels and "external uncertainty", which is related to the occurrence of external events. We propose three innovations to better account for uncertainty in AES design and test their attractiveness through a choice experiment. We find that proposing contracts that allow suspending the conditions of the contract for one year enhances participation. |

| Abstract: | Violent conflicts, particularly at election times in Africa, are a common cause of instability and economic disruption. This paper studies how firms react to electoral violence using the case of Kenyan flower exporters during the 2008 post-election violence as an example. The violence induced a large negative supply shock that reduced exports primarily through workers' absence and had heterogeneous effects: larger firms and those with direct contractual relationships in export markets suffered smaller production and losses of workers. On the demand side, global buyers were not able to shift sourcing to Kenyan exporters located in areas not directly affected by the violence nor to neighboring Ethiopian suppliers. Consistent with difficulties in insuring against supply-chain risk disruptions caused by electoral violence, firms in direct contractual relationships ramp up shipments just before the subsequent 2013 presidential election to mitigate risk. |
