Information Gathering and Marketing

Consumers have only partial knowledge before making a purchase decision, but can acquire more‐detailed information. Marketing makes it easier or harder for these consumers to do so. When consumers are ex ante heterogeneous, the firm might choose an intermediate marketing strategy for two quite different reasons. First, as a nonprice means of discrimination—it can make information only partially available, in a way that induces some, but not all, consumers to acquire the information. Second, when the firm cannot commit to a given investment in ensuring quality, the marketing and pricing strategy can act as a commitment device.     

Herding versus Hotelling: Market Entry with Costly Information

Why do businesses such as fast‐food restaurants, coffee shops, and hotels cluster? In the classic analysis of Hotelling, firms cluster to attract consumers who have travel costs. We present an alternative model where firms cluster because one firm is free riding on another firm's information about market demand. One consequence of this free riding is that an informed firm might forego a market that it knows to be profitable. Furthermore, an uninformed firm might earn higher profits when research costs are high, because it can credibly commit to ignorance.     

Strategic behavior in a service industry

A model of service duopoly is formulated, where the arrival of customers and their service time in the firm are stochastic. The firms first choose the service capacity, and given the capacity they then choose the price in a Bertrand competition. Capacity choices have a negative externality on the competitor, since increased capacity in one firm decreases its expected full price (price plus cost of waiting) and leads to a flow of customers from the other firm. If the firms choose capacities strategically, it is optimal to underinvest compared to the non‐strategic case, but this result may arise in different ways. By underinvesting the firms commit themselves to longer queues (lower quality) to relax price competition. Copyright © 2002 John Wiley & Sons, Ltd.     

Managerial optimism and investment choice

This paper analyzes whether it might be desirable for a firm to hire an overoptimistic manager to commit to a certain R&D strategy. I consider a Cournot model with an ex‐ante R&D stage where firms can invest in cost reduction before product market competition takes place. I show that firms want to hire overoptimistic managers and argue that a manager's type may serve as a substitute for strategic delegation via contracts. Copyright © 2010 John Wiley & Sons, Ltd.     

Strategic Corporate Social Responsibility Activities and Corporate Governance in Imperfectly Competitive Markets

We investigate the incentives of firms' owners to commit voluntarily to corporate social responsibility (CSR) activities in an oligopolistic market. The socially responsible attributes attached to products are considered as credence goods, with consumers forming expectations about their existence and level. We show that hiring an ‘individually’ socially responsible CEO and delegating to him the CSR effort and market decisions acts as a commitment device for the firm's owners and credibly signals to consumers that the firm will undertake the ‘missioned’ CSR activities. We also find that CSR activities are welfare enhancing for consumers and firms and thus, they should be encouraged. Copyright © 2013 John Wiley & Sons, Ltd.     

Victim or Victimizer: Firm Responses to Government Corruption

What is the relationship between government corruption and firm performance? To address this question, I conduct a review of articles published in the leading management journals on government‐business interactions pertaining to rent‐seeking activities and integrate findings from the fields of international business, social issues in management, public organization, institutional change, and corporate political activity. I find that while much empirical work corroborates the earlier findings suggesting a corrosive impact of government corruption on firm performance in general, management research also points to the heterogeneous impact of government corruption on individual firm performance, driven by the strategic activities conducted by firms in response to corruption. I propose an integrative model of firm strategy vis‐à‐vis corruption that predicts the activity choice of the firm as predicated by its organizational structure, political resources, industry regulation, and surrounding political and social institutions.     

When Does a Firm Support Substitute Open Source Programming?

Software firms are observed to support programmers' communities, which develop rival open source programs. A firm selling a copyright program has an incentive to support substitute copyleft programming when support creates compatibility between the programs and programs exhibit network effects. Costly compatibility benefits the firm as its consumers gain access to the community's services but may also hurt the firm because it cannot profit from the valuation difference between incompatible networks. The incentive arises under a weak network effect even when the consumers' benefit is small. Standardization and enlarging the open source programmers' community do not always increase welfare.     

Loyalty Rewards Facilitate Tacit Collusion

Using a dynamic overlapping‐generations model, we show that loyalty rewards robustly facilitate tacit collusion. We compare the sustainability of tacit collusion when uniform prices are used, when loyal customers are rewarded without using commitment, and when loyalty rewards are implemented by committing to offering customers either lower fixed repeat‐purchase prices or fixed repeat‐purchase discounts. We find that, relative to uniform prices, rewarding loyalty without using commitment on the equilibrium path makes tacit collusion easier to sustain, because a deviating firm is unable to steal one period of industry profit before losing all future profits. When loyalty rewards are offered by firms committing to repeat‐purchase prices, collusion is even easier to sustain, because a deviating firm cannot renege on its discounted price for repeat‐purchase customers. When firms commit to repeat‐purchase discounts, they also commit to lowering the price for their repeat‐purchase customers if they undercut the regular price, rendering tacit collusion to be even more readily sustainable. Our results hold whether products are homogeneous or horizontally differentiated as in a Hotelling model.     

Information Flow Analysis and the Theory of the Firm

In this paper, I examine the role the firm plays in economizing on information flows that are required to turn raw materials and ideas into products and services used by final consumers. Specifically, I argue that scale economies associated with complex information transfers are an important benefit of integration. This argument is distinct from theories that are based on incentives and leads to different or more refined conclusions in some cases. The differences are explored in the context of literature on specific assets, vertically related monopolies, and physical asset ownership. Information flow analysis also arms managers with a framework for addressing organizational questions beyond firm‐boundary decisions such as intrafirm decisions.

Targeted advertising,platform competition,and privacy

Targeted advertising can benefit consumers through lower prices for access to web sites. Yet, if consumers dislike that web sites collect their personal information, their welfare may go down. We study competition for consumers between web sites that can show targeted advertisements. We find that more targeting increases competition and reduces the web sites' profits, but yet in equilibrium web sites choose maximum targeting as they cannot credibly commit to low targeting. A privacy protection policy can be beneficial for both consumers and web sites. If consumers are heterogeneous in their concerns for privacy, a policy that allows choice between two levels of privacy will be better. Optimal privacy protection takes into account that the more intense competition on the high‐targeting market segment also benefits consumers on the less competitive segment. Consumer surplus is maximized by allowing them a choice between a high‐targeting regime and a low‐targeting regime which affords more privacy.     

Optimal Two‐Part Pricing under Demand Uncertainty

This paper examines the pricing behavior of a risk‐averse monopolistic firm under demand uncertainty. The firm produces a single good at a constant marginal cost. To facilitate sales, the firm uses a two‐part pricing contract that includes a membership fee and a selling price per unit. The good is sold to a continuum of heterogeneous consumers who are subject to a common demand shock. We show that the global and marginal effects of risk aversion are to push the unit price closer to the constant marginal cost and to shrink the market coverage so as to limit the firm’s risk exposure to the demand uncertainty. The more risk‐averse firm as such charges a higher membership fee to consumers. We further show that an increase in the fixed cost of production induces the firm to lower (raise) the unit price, to raise (lower) the membership fee, and to shrink (enlarge) the market coverage under decreasing (increasing) absolute risk aversion. The firm’s optimal two‐part pricing contract, however, is unaffected by changes in the fixed cost under constant absolute risk aversion. Finally, we show that a mean‐preserving‐spread increase in the demand uncertainty induces the firm to lower the unit price, to raise the membership fee, and to shrink the market coverage under either decreasing or constant absolute risk aversion. The firm’s risk preferences as such play a pivotal role in determining the optimal two‐part pricing under demand uncertainty. Copyright © 2013 John Wiley & Sons, Ltd.     

Learning in Advance Selling with Heterogeneous Consumers

Advance selling occurs when consumers order a firm's product prior to the regular selling season. It reduces uncertainty for both the firm and the buyers and enables the firm to better forecast its future demand. The distinctive feature of this paper is that there are both experienced and inexperienced consumers, with the former knowing their valuations of the product in advance. We show that pre‐orders from experienced consumers lead to a more precise forecast of future demand by the firm and that the optimal pre‐order price may be at a discount or a premium relative to the regular selling price.

Choosing the Quality of the Fit between Complementary Products

In this paper, I examine how firms should position their complementary products. I assume that there are two competing firms, each producing two complementary products. Each firm decides whether to employ strategies that enhance the quality of the fit (the degree of complementarity) between its pair of complementary products before competing in prices. The consumers have heterogeneous tastes for the four possible bundles. They are willing to pay a price premium in order to purchase a bundle from the same firm if this firm chose to make such bundle more attractive. I find that increasing the degree of complementarity between a firm's complementary products intensifies price competition and often leads to smaller profits. Only when complementarity‐enhancing strategies significantly increase the demand for a firm's matching bundle, does the firm benefit from employing them. The highest profits for both firms are obtained when both firms do not employ complementarity‐enhancing strategies. Deteriorating the quality of the fit between one's own and a rival's complementary products is never profitable.     

Firm entry,product repositioning and welfare

We show that the entry of a second firm in a horizontally differentiated market (ala Hotelling) may harm consumers as prices increase and consumer’s surplus possibly decrease. We first derive the price and the consumer’s surplus of a monopoly which is located at the center of the market. When a second firm enters the market the first firm repositions and the two firms locate at their equilibrium points. Although competition adds to variety and increases consumer’s surplus, the post entry increase in price may outweight the gains from extra variety and make consumers worse off.     

Behavior‐ and characteristic‐based price discrimination

We develop a model of behavior‐ and characteristic‐based discriminatory pricing where consumers are heterogeneous both in tastes and in price sensitivity. Each firm is able to distinguish between the consumers that have bought from it and those that have bought from the rival. Furthermore, each firm learns the price sensitivity of their own consumers. We show that using this additional information may yield higher profits than uniform pricing provided that consumers are heterogeneous enough with respect to price sensitivity. We also discuss consumer surplus implications of such behavior‐ and characteristic‐based price discrimination, and we show that the impact of price discrimination depends on both the consumer type and the level of consumers’ heterogeneity.     

Focused Firms and the Incentive to Innovate

This paper explores the possibility that a firm may make a credible strategic commitment to high levels of innovation by limiting its horizontal or vertical scope. Specifically, I develop a model in which a firm decides whether to undertake an innovation that affects a system of products, which can also be interpreted as multiple stages of the production process. The products are technologically related, and innovation in the core product is assumed to impose costs on the producers of ancillary products, due to cannibalization of the old technology and redesign or retooling costs, for example. I demonstrate that a firm may optimally and credibly commit to innovate by choosing to be a focused firm and licensing the production of the ancillary product, even when licensees are inefficient. In stark contrast to the irrelevance results of the strategic delegation literature, this commitment may be credible even when licensing contracts are renegotiable, but only if licensees are sufficiently inefficient.     

The Role of Public Information in Corporate Social Responsibility

Many of the attributes that make a good “socially responsible” (SR) are credence attributes that cannot be learned by consumers either through search or experience. Consumers, then, use for their purchasing decisions “noisy” information about these attributes obtained from potentially contradictory channels (media, advertisement, NGOs). In this paper we model such informational framework and show the positive relationship between the accuracy of the information transmitted to consumers and corporate social responsibility. We also show that a firm may be tempted to add noise to the information channel (through lobbying of the media), which might reduce the supply of the SR attributes and even harm the firm itself (with lower profits). It might then be profitable to the firm to commit ex ante to not manipulate the information regarding the firm's business practices (e.g., with a partnership with an NGO). Finally, we extend our model to a competition framework endogenizing the number of firms active in the SR segment. We show both that in more transparent markets a larger number of firms will be SR, and that in a market with more intense competition, a higher degree of transparency is required in order to sustain a given number of SR firms.     

Collusive equilibria with switching costs: The effect of consumer concentration

I study the ability of two competing firms to set collusive prices in markets where consumers have switching costs. In consumer markets (with a small number of consumers), I find an antifolk result in which collusion, in the presence of switching costs, does not arise with patient firms. Patient firms compete aggressively and consumers expect a large utility. A collusive equilibrium is unstable because a deviating firm incorporates the future consumer utility in its deviating price. Also, consumers have a strategic impact so, with the prospects of large utility, they decide to switch to destabilize the firms' collusive agreement. These results do not eventuate in markets with a large number of consumers. In mass markets (a continuum of consumers), a single consumer lacks a strategic impact to destabilize a collusive agreement and a deviating firm cannot appropriate the consumer utility when deviating from collusion. Collusion, then, becomes straightforward to achieve. We show that for any number of consumers, switching costs make collusion easy to sustain.     

Corporate social responsibility,durable‐goods and firm profitability

Utilizing a two‐period durable‐goods framework, we show that in uncommitted sales markets a firm may earn higher profits as it increases its level of corporate social responsibility (CSR). We find that this occurs even though CSR has no direct impact other than increasing the durable‐goods firm's manufacturing costs. We show that in sales markets, CSR may allow the firm to credibly commit itself to lower production in the future. This, in turn, can enhance their profits even though the CSR activities are costly and provide no direct demand or marketing benefit in our model. This is important because it provides another, hereto unexplored, strategic rationale for the willingness of profit‐maximizing firms to undertake costly CSR activities.

Customization with Vertically Differentiated Products

We consider a duopoly market with heterogeneous consumers. The firms initially produce vertically differentiated standard products located at the end points of the variety interval. Customization provides ideal varieties for consumers but has no effect on quality. The firms first choose whether to customize their products, then engage in price competition. We show that the low‐quality firm never customizes alone; customization becomes more likely as the difference between the firms’ qualities increases; and less likely as the fixed cost of customization increases. We extend the base model by relaxing two important assumptions—uniform pricing and exogenous quality. The main conclusions with uniform pricing continue to hold when price customization is allowed. In the second extension the firms’ qualities are endogenously determined. We show that the firms choose to be either substantially differentiated in quality or nondifferentiated.
