This dissertation develops variants of the well-known Hotelling’s location model to examine the nature of competition in the audit market where audit firms make strategic specialization and pricing decisions. In a multi-period spatial oligopoly model of auditing competition, audit firms obtain market power through their service specialization with respect to client characteristics relevant to audit production. This market power allows audit firms to price discriminate among clients. Competition among audit firms is localized: an audit firm optimally charges a client, to whom it has the lowest auditing cost to serve, the marginal auditing cost of the second lowest-cost audit firm. These equilibrium audit firms’ pricing strategies result in an allocation of clients’ surplus and audit firms’ profits that lies in the core of the economy. The existence of a specialization-pricing equilibrium is also established. In equilibrium, given its rivals’ specializations, each audit firm’s profit is maximized by choosing a specialization that maximizes the social welfare (the sum of clients’ surplus and audit firms’ profits). Moreover, audit firms never choose the same specialization in equilibrium. Instead, in order to earn rents as ‘local monopolists’, audit firms differentiate themselves from each other. This result is consistent with a widely held notion that audit firms search for ‘niche’ markets, such as industry specialization, to increase their profits. The dissertation then focuses on a two-period spatial duopoly model in which the market power created by audit firm specialization is now further fortified by the presence of auditors’ learning and clients’ switching costs. In this case, audit firms optimally price discriminate among clients by offering them ‘specialization-and-relationship-specific’ audit fee schedules. The practice of ‘low-balling’ is found to be a natural consequence of the competition among audit firms. However, low-balling occurs only in a certain market segment where audit firms compete quite fiercely. The analysis also demonstrates how equilibrium audit fee schedules, audit firms’ specializations and profits, clients’ surplus, and social welfare depend on the auditing costs, the learning rate, and the switching costs. Some interesting policy implications are illustrated. Finally, the model is used to analyze the impact of banning audit firms from the practice of low-balling. It is demonstrated that even though a policy of banning low-balling always reduces competition, it improves social efficiency in some cases.

This dissertation contains three essays on debts of different forms that make contributions to the areas of international macroeconomics and spatial economics. In particular, the first two essays study sovereign debts. They examine sovereign default behaviors together with interactions between sovereign defaults and countries’ costs of borrowing. The third essay looks at bank loans. It explores the possibility of understanding economic agglomeration through distance-related financial frictions firms face when borrowing from banks.
