Advance Purchase Discounts Versus Clearance Sales

This article considers advance selling problems. It explains why some goods (e.g. airline tickets) are sold cheap to early buyers, while others (e.g. theatre tickets) offer discounts to those who buy late. We derive the profit maximising selling strategy for a monopolist when aggregate demand is certain but buyers face uncertainty about their individual demands. When aggregate demand exceeds capacity, both Advance Purchase Discounts as well as Clearance Sales might be optimal. We determine how the comparison of these price discrimination strategies depends on the rationing rule, capacity costs and the availability of temporal capacity limits, price commitment and resale.

When Should Leaders Share Information with their Subordinates

We show that when leaders share some of their information with subordinates, decision making is subject to a motivational bias; leaders make the decisions their subordinates want to see. As this bias increases with the quality of the shared information, an improvement of an organizations information might even decrease its efficiency. As a consequence, information sharing is not always optimal. We show however that self-confidence can help the leader to overcome his motivational bias, thus making information sharing more attractive. Conversely, we find that information sharing can help to curb the autocratic tendencies of a self-confident leadership. We conclude that a policy of information sharing and the appointment of a self-confident leadership are most effective when they go hand in hand.

The timing of contracting with externalities

Abstract This paper endogenizes the timing of bilateral contracting between one principal and multiple agents in the presence of externalities. Contracting simultaneously with all agents is optimal for the principal if externalities become weaker the more an agent trades. If instead externalities become stronger, sequential negotiations might benefit the principal as they lower the agents’ outside options. Under some linearity conditions, the principals preferences with respect to different timings of contracting are opposed to their efficiency ranking.

The distribution of talent across contests

Do the contests with the largest prizes attract the most able contestants? Do contestants avoid competition? In this paper we show that the distribution of abilities plays a crucial role in determining contest choice. Positive sorting exist only when the proportion of high ability contestants is sufficiently small. As this pro- portion increases, contestants shy away from competition and sorting decreases. Eventually, contests with smaller prizes attract stronger participants, i.e. there exists negative sorting. We test our theoretical predictions using a large panel data set containing contest choice over three decades. We use exogenous variation in the participation of highly able competitors to provide empirical evidence for the relationship between prizes and sorting.

Competition Amongst Contests

This article analyses the allocation of prizes in contests. While existing models consider a single contest with an exogenously given set of players, in our model several contests compete for participants. As a consequence, prizes not only induce incentive effects but also participation effects. We show that contests that aim to maximize players’ aggregate effort will award their entire prize budget to the winner. In contrast, multiple prizes will be awarded in contests that aim to maximize participation and the share of the prize budget awarded to the winner increases in the contests’ randomness. We also provide empirical evidence for this relationship using data from professional road running. In addition, we show that prize structures might be used to screen between players of differing ability.

Market Structure and Advance Selling

When products are sold in advance, i.e. prior to consumption, consumers trade off an early, uninformed purchase at a low price against a late, informed purchase at a high price. This paper considers the effect of market structure on the prevalence of advance selling. We show that in an oligopolistic market with multi-product firms, advance selling (with its associated allocative inefficiency) is decreasing in market concentration when the consumers’ preference uncertainty is high but can be increasing when uncertainty is low.

Project selection and execution in teams

We use a mechanism-design approach to study a team whose members select a joint project and exert individual efforts to execute it. Members have private information about the qualities of alternative projects. Information sharing is obstructed by a trade-off between adaptation and motivation. We determine the conditions under which first-best project and effort choices are implementable and show that these conditions can become relaxed as the team grows in size. We also characterize the second-best mechanism and find that it may include a “motivational bias,” that is, a bias in favor of the teams initially preferred project, and higher-than-optimal effort by uninformed team members.

Competition in the Presence of Individual Demand Uncertainty

This paper sheds light on an empirical controversy about the effect of competition on price discrimination. We introduce individual demand uncertainty into Hotelling’s model of product differentiation and show that firms offer advance purchase discounts. Consumers choose between an early (uninformed) purchase at a low price and a late (informed) purchase at a high price. Competing firms offer higher discounts in order to secure a large market share in advance. Our main result shows that whether competition has a positive or negative effect on price dispersion depends on the level of demand uncertainty and the degree of product differentiation.

Dynamic adverse selection with a patient seller

This paper considers dynamic bilateral trade with short-term commitment. We show that, when the seller is more patient than the buyer, there exist systematic differences between the optimal selling and renting mechanisms. While the former consists of simple price-posting, the latter induces the buyer to choose between a secure- and a random-delivery contract. Allowing for mechanisms more general than price-posting reduces the sellers cost of learning the buyers valuation in the renting case. Renting leads to more learning than selling but (unless the horizon is sufficiently long) only when general mechanisms are available. Our results contrast with the common view that the restriction to price-posting is innocuous and that informational asymmetries are more persistent under renting than under selling.
