Book Description
This dissertation consists of three chapters on principal-agent models. Chapter 2 studies an optimal contract design problem in a principal-framework whereas chapter 3 is an empirical investigation of the incentive contracts in the market of top executives. Chapter 4 is a theoretical chapter exploring welfare impacts of the structure in a top-level bureaucracy. In the first chapter, I consider a dynamic moral hazard model where the principal offers a series of short-run contracts. I study the optimal mix of two alternative instruments for incentive provision: a performance based wage (a "carrot") and a termination threat (a "stick"). At a given point in time, these instruments are substitutes in the provision of incentives. I am particularly interested in the dynamic interaction of these two instruments. Both carrot and stick are used more intensively as the agent approaches the end of her finite life. The sharing of the surplus of the relationship plays a key role: a termination threat is included in the optimal contract if and only if the agent's expected future gain from the relationship is sufficiently high, compared to the principal's expected future gain. Also, a termination threat is more likely to be optimal if output depends more on "luck" than on effort, if the discount factor is high, or if the agent's productivity is low. Having inspired from chapter 2, chapter 3 of the dissertation is an empirical study of the contracts of Chief Executive Officers (CEO). Direct pay for performance and a threat of termination when performance is low are two important instruments to incentivize CEOs. This chapter is an empirical analysis of the use of these two incentive devices and how they depend on tenure and managerial ability. For managers promoted from within a firm, ability is proxied by their age at the time of promotion. For managers hired from outside, I instead rely on constructed measures of "reputation", based on media citations over time windows of different length. Using a sample of firms, listed in S & P 1500 over the period 1998-2008, I find that CEO compensation and the threat of forced turnover are used as incentive devices throughout tenure. Even though the results indicate that pay increases as the CEO is more senior in her tenure, there is no strong evidence that termination threat follows a particular time pattern. For outsider CEOs, a better reputation increases pay and decreases the likelihood of forced turnover, with stronger effects for more current reputational measures. Regarding the impacts of reputation on the tenure-pay relationship, only more current measures have a significant and negative effect. Managerial ability, as proxied by age-at-promotion for insiders and as proxied by reputation for outsiders, decreases the likelihood of forced turnover. More current reputation measures, as in the case of total pay, have a larger impact of likelihood of turnover. Chapter 4 investigates the welfare implications of multiple principals in the highest level of bureaucracy. An agent has to carry out two separate tasks, which can either be organized by two separate principals, or combined under one principal. The relationship between the top level (the principals) and the lower level (agent) of the bureaucracy is a "principal-agent problem". The existence of multiple principals generates a "common agency". The analysis reveals that the optimal hierarchy depends on the existence of "rents" from office that the principals enjoy. If there are no rents, the two systems are equally welfare-efficient. A single-principal model dominates common agency otherwise.

Book Description
There have been systematic attempts over the last twenty-five years to explore the implications of decision making with incomplete information and to model an 'economic man' as an information-processing organism. These efforts are associated with the work of Roy Radner, who joins other analysts in this collection to offer accessible overviews of the existing literature on topics such as Walrasian equilibrium with incomplete markets, rational expectations equilibrium, learning, Markovian games, dynamic game-theoretic models of organization, and experimental work on mechanism selection. Some essays also take up relatively new themes related to bounded rationality, complexity of decisions, and economic survival. The collection overall introduces models that add to the toolbox of economists, expand the boundaries of economic analysis, and enrich our understanding of the inefficiencies and complexities of organizational design in the presence of uncertainty.

Book Description
Complex systems are systems that comprise many interacting parts with the ability to generate a new quality of collective behavior through self-organization, e.g. the spontaneous formation of temporal, spatial or functional structures. These systems are often characterized by extreme sensitivity to initial conditions as well as emergent behavior that are not readily predictable or even completely deterministic. The recognition that the collective behavior of the whole system cannot be simply inferred from an understanding of the behavior of the individual components has led to the development of numerous sophisticated new computational and modeling tools with applications to a wide range of scientific, engineering, and societal phenomena. Computational Complexity: Theory, Techniques and Applications presents a detailed and integrated view of the theoretical basis, computational methods, and state-of-the-art approaches to investigating and modeling of inherently difficult problems whose solution requires extensive resources approaching the practical limits of present-day computer systems. This comprehensive and authoritative reference examines key components of computational complexity, including cellular automata, graph theory, data mining, granular computing, soft computing, wavelets, and more.

Book Description
Three models of a privately informed contract designer (a principal) are examined. In the first, I study how much private information the principal wants to acquire before offering a contract to an agent. Despite allowing her to acquire all information for free, I prove in a general environment that there is a nontrivial set of parameters for which it is strictly suboptimal for the principal to be completely informed, regardless of the continuation equilibrium following any information acquisition choice. This result holds even when the principal is able to employ the most general mechanisms available and, in particular, when she can choose her most favourable full-information continuation equilibria. Further, in a specialized environment I characterize the principal's optimal information choice. The second is a two-state principal-agent model with moral hazard in which the principal knows the state but the agent does not. This model is relevant to situations where an employer has private information about the productivity of a worker in a particular task while the worker has private information about the effort she exerts on the job. Much of the literature on this subject restricts the employer to offer contracts that leave her no discretion once a contract is accepted, while more general contracts may allow the employer to exercise discretion after acceptance; such contracts are called menu-contracts. I show when the employer can obtain strictly higher expected payoffs by offering menu-contracts than by offering the restricted contracts used in the literature. The final model studies the ability of a bidder in an auction to organize collusion among her rival bidders and the resulting impact of this collusion on the seller. Bidders valuations are private information. I show that in a two bidder, discrete, independent private-value auction, the seller earns less when a bidder can offer her rival a collusion proposal than in the absence of collusion. This contrasts with a cele- brated result by Che and Kim ("Robustly collusion-proof implementation". Econometrica, 74(4):1063-1107, July 2006) stating that for such auctions there is a mechanism that eliminates all the effects of collusion. Che and Kim and much of the literature assume an uninformed third-party organizes collusion.

Book Description
This dissertation consists of three chapters in microeconomic theory with a focus on dynamic games and learning. It has applications in political economy, contracts, and industrial organization. In the first chapter, I study censorship in a dynamic game between an informed agent and an uninformed evaluator. Two types of public news are informative about the agents ability -- a conclusive good news process and a bad news process. However, the agent can censor bad news, at some cost, and will censor it if and only if this secures her a significant increase in tenure. Thus, the evaluator faces a bandit problem with an endogenous news process. When bad news is conclusive, the agent always censors when the public belief is sufficiently high, but below a threshold, she either stops censoring or only censors with some probability, depending on the information structure. The possibility of censorship hurts the evaluator and the good agent, and it may also hurt the bad agent. However, when bad news is inconclusive, I show that the good agent censors bad news more aggressively than the bad agent does. This improves the quality of information, and may benefit all players -- the evaluator, the bad agent, and the good agent. The second chapter examines the nature of contracts that optimally reward innovations in a risky environment, when the innovator is privately informed about the quality of her innovation and must engage an agent to develop it. I model the innovator as a principal who has private but imperfect information about the quality of her project: the project might be worth exploring or not, but even a project of high quality may fail. I characterize the best equilibrium for the high type principal, which is either a separating equilibrium or a pooling one. Due to the interaction between the signaling incentives of the principal and dynamic moral hazard of the agent, the best equilibrium induces inefficiently early termination of the high quality project. The high type principal is forced to share the surplus - with the agent in the separating equilibrium, or the low type principal in the pooling equilibrium. A mediator, who offers a menu of contracts and keeps the agent uncertain about which contract will be implemented, can increase the payoff of the high type principal to approximate her full information surplus. In the third chapter, I study how competition between platforms affects the process of social learning. Especially, how product differentiation affects that process. Che and Hörner (2018) show that a monopolistic platform may want to over-recommend consumers in the early phase to gather and learn information for the sake of future consumers. I show that when platforms do not differentiate their products, duopoly competition dramatically reduces the early experimentation, and the Full Transparency policy is the unique equilibrium strategy for both platforms. When platforms differentiate their products, I show that the equilibrium strategy is in between the Full Transparency policy and the optimal policy in the monopolistic case, and depends on how differentiated the products are
