Book Description
Pricing is one of the most vital topic within the theory of Microeconomics. A firm can use a variety of pricing strategies to maximize its profit, gain market share, enter a new market or prevent potential entrants. This dissertation contains three essays exploring the equilibrium effect of various pricing strategies. The first chapter, co-authored with David S. Sibley and Wei Zhao, examines the effects of two types of vertical restrictions that are found in the cigarette and soft drink industries. In one case, a manufacturer gives discounts to the retailer in return for a commitment that the manufacturers product be priced no higher than a specified competing product. We refer to this as a vertical MFN (VMFN). The second is an agreement where the retailer commits to price in such a way that its margin on the product is no higher than the equivalent margin on a specified competing product. We refer to this as a vertical margin constraint (VMC). We show that the VMFN results in equilibrium prices that are higher than in a benchmark case without the constraint. In contrast, the VMC constraint leads to uniformly lower prices. The distributional effects are different, too. The VMFN tends to raise manufacturer profits, if different manufacturers produce very similar products. The retailer is worse off. The opposite effects arise in the VMC case. The second chapter analyzes firms giving switching discounts to consumers who purchased from their rivals rather than own past customers. By analyzing a two-period duopoly model with horizontal differentiation, we find that when the intrinsic value of the product is not high enough to make sure that the consumers will buy at least one of the product, the dynamic price path featured in the previous literature involving a raised second period price for customers with relatively high valuation will be reversed. Moreover, offering switching discounts results in a profit lower than the benchmark case, where such a pricing strategy is unavailable. The third chapter discusses how bundled discounts affect firm's decision of extending the product line by versioning the product through horizontal differentiation or vertical quality degrading. We propose a framework showing that inter-firm mixed bundling schemes may incentivize the introduction of a differentiated product, while in the absence of bundling it may not be profitable to do so. However, the consumer's surplus gain as a result of intensified competition and increased variety of goods from versioning will be dominated by the negative welfare impacts of bundling.

Abstract: I analyze three settings of pricing dynamics. In the first chapter, I describe a new method of estimating the New Keynesian Phillips Curve. Specifically, this study introduces a new proxy for the real marginal cost term as well as a new instrument set, both of which are based on the micro foundations of the vertical chain of production. I find that the new proxy, based on input prices as opposed to wages, provides a more robust and significant fit to the model. Instruments that are based on the vertical production chain appear to be both more valid and relevant. In the second chapter, I describe the dynamics of pricing in the airline industry. Specifically, this chapter analyzes the effects of market structure on price dispersion using panel data. I find that competition has a negative effect on price dispersion, in line with the traditional textbook treatment of price discrimination. Furthermore, the effects of competition on price dispersion are most significant on routes that we identify as having consumers characterized by relatively heterogeneous elasticities of demand. On routes with a more homogeneous customer base, the effects of competition on price discrimination are largely insignificant. These results show that competition acts to erode the ability of a carrier to price discriminate, resulting in reduced overall price dispersion. In the third chapter, I analyze airline price dispersion in order to determine the effects of the business cycle on markup variations. While most macroeconomic studies find a counter-cyclical markup, this study suggests that the markup in the airline industry is pro-cyclical. Using a panel analysis, I find that the output gap explains a larger positive degree of price dispersion on routes with a heterogeneous consumer base relative to routes with a homogenous consumer base. This suggests that the markup charged to price inelastic consumers rises during peaks in the business cycle.

Abstract: This dissertation develops three essays on dynamic pricing to investigate two important topics in industrial organization: price dispersion and price discrimination. The first essay considers a stylized model of dynamic price competition in which each seller sells one unit of a homogeneous commodity by posting prices in every period to maximize the expected profits with discounting. A random number of buyers come to the market in each period. Each buyer demands at most one unit of the good, and they all have a common reservation price. They know all prices posted by all firms in the market; hence search is costless. I show that when there is a positive probability of excess demand, the model has a unique (symmetric) mixed-strategy equilibrium. In this equilibrium, each seller posts a price in every period according to a non-degenerate distribution, which is determined by the number of sellers remaining in the market in that period. Sellers play mixed strategies as they are indifferent between selling sooner at a lower price and waiting to sell at a higher price later. Thus, price dispersion not only exists in every period among firms, but also persists over time. In the second essay, I consider a monopolist who can sell vertically differentiated products over two periods to heterogeneous consumers. Consumers each demand one unit of the product in each period. In the second period, consumers are sorted into different segments according to their first-period choice, and the monopolist can offer different menus of contracts to different segments. In this way, the monopolist can price discriminate consumers not only by product quality, but also by purchase history. I fully characterize the monopolist's optimal pricing strategy when the type space is discrete and a simple condition is given to determine whether the monopolist should price discriminate consumers by product quality in the first period. When the consumers' type space is a continuum, I show that there is no fully separating equilibrium, and some properties of the optimal menu of contracts (price-quality pairs) are characterized within the class of partition PBE (Perfect Bayesian Equilibrium). The monopolist will offer only one quality in the first period when the social surplus function is log submodular or the firm and consumers are patient. If it is optimal for the firm to offer only one quality in the first period, the optimal market coverage in the first period is smaller than that in the static model. Furthermore, in equilibrium there are some high-type consumers choosing to downgrade the product in the second period, a phenomenon that has never been addressed in the literature. In the second essay, when the consumers' type space is a continuum, the analysis of the optimal menu of contracts is restricted within the class of partition PBE. The third essay provides a justification for this qualification. I ask whether an optimal menu of contracts can induce a non-partition continuation equilibrium by scrutinizing the example constructed by Laffont and Tirole (1988). They construct a non-partition continuation equilibrium for a given first-period menu of incentive contracts and conjecture that this continuation equilibrium need not be suboptimal for the whole game under small uncertainty. I construct two first-period incentive schemes leading to a partition continuation equilibrium and show that, regardless of the extent of uncertainty, their non-partition continuation equilibrium generates a smaller payoff than one of two partition continuation equilibria for the principal. In this sense, Laffont and Tirole's menu of contracts, giving rise to a non-partition continuation equilibrium, is not optimal. I provide an intuition behind this result, hoping to shed light on the problem of dynamic contracting without commitment.

Book Description
The economic crisis is also a crisis for economic theory. Most analyses of the evolution of the crisis invoke three themes, contagion, networks and trust, yet none of these play a major role in standard macroeconomic models. What is needed is a theory in which these aspects are central. The direct interaction between individuals, firms and banks does not simply produce imperfections in the functioning of the economy but is the very basis of the functioning of a modern economy. This book suggests a way of analysing the economy which takes this point of view. The economy should be considered as a complex adaptive system in which the agents constantly react to, influence and are influenced by, the other individuals in the economy. In such systems which are familiar from statistical physics and biology for example, the behaviour of the aggregate cannot be deduced from the behaviour of the average, or "representative" individual. Just as the organised activity of an ants’ nest cannot be understood from the behaviour of a "representative ant" so macroeconomic phenomena should not be assimilated to those associated with the "representative agent". This book provides examples where this can clearly be seen. The examples range from Schelling’s model of segregation, to contributions to public goods, the evolution of buyer seller relations in fish markets, to financial models based on the foraging behaviour of ants. The message of the book is that coordination rather than efficiency is the central problem in economics. How do the myriads of individual choices and decisions come to be coordinated? How does the economy or a market, "self organise" and how does this sometimes result in major upheavals, or to use the phrase from physics, "phase transitions"? The sort of system described in this book is not in equilibrium in the standard sense, it is constantly changing and moving from state to state and its very structure is always being modified. The economy is not a ship sailing on a well-defined trajectory which occasionally gets knocked off course. It is more like the slime described in the book "emergence", constantly reorganising itself so as to slide collectively in directions which are neither understood nor necessarily desired by its components.
