The main theme of this dissertation are departures from standard assumptions in economic theory, specifically, departures from the model of subjective expected utility in decision theory.
Part 1 axiomatizes the robust control criterion of multiplier preferences introduced by Hansen and Sargent (2001). The axiomatization shows that the class of multiplier...
This dissertation studies whether stock mergers creates value for acquirers. The first chapter of this dissertation conducts a comprehensive review of the existing merger literature relevant to this topic. It includes existing merger theories, empirical studies on whether mergers are value destroying or value creating, and methodological issues on empirical...
In the first chapter we analyze profits and efficiency implications of a relation between an upstream duopoly and downstream monopoly in Hotelling linear city model. While exclusive contracts maximize the monopolist's profit, at the same time socially they are inefficient. Linear prices, while more efficient, usually also do not achieve...
In the first part of the dissertation I study mechanism design under limited communication. Chapter 1 offers a detailed analysis of auctions with simultaneous limited communication. I solve for both welfare and revenue maximizing equilibria. The striking feature of optimal equilibria is that they are asymmetric even when the setup...
This dissertation contains three essays that investigate various factors affecting firms' choice of quality in the context of nursing homes.
The first essay examines how strategic interactions with competitors affect quality levels selected by nursing homes. I explore nursing homes' responses to minimum nurse staffing standards imposed in two large...
Ethicity, race and gender play an important role in labor markets; labor market outcomes such as hiring and compensation are very different across different social groups. These differentials are partly the result of differences in productivity and preferences and partly the result of discrimination. Chapter two uses an audit study...
The first chapter of this dissertation studies a continuous-time agency model where the agent controls the drift of the geometric Brownian motion firm size. The changing firm size generates partial incentives, analogous to awarding the agent equity shares according to her continuation payoff. When the agent is as patient as...
In the first chapter of my dissertation, I study the effects of an exogenous increase in government spending in models incorporating price and wage nominal rigidities. I find that the effects of price stickiness on the output multiplier depend crucially on the behavior of the monetary authority. If the monetary...
This dissertation explores price differences observed in the market. While some differences are necessitated by market conditions, the others are strategic. I illustrate the former in a study of electricity spot markets in Italy and the latter for the video rental industry.
The first project examines the welfare gains from...
The first chapter investigates the offshoring decision from a network capacity investment perspective. We analyze a firm that manufactures two products to serve two geographically separated markets using a common component and two localized final assemblies. Two strategic network design questions arise naturally: (1) Should the common part be produced...
