Competitive provision of tune-ins under common private information

Television (TV) stations forego millions of dollars of advertising revenues by airing tune-ins (preview advertisements) for their upcoming programs. In this paper, I analyze the equilibrium as well as welfare properties of tune-ins in a duopolistic TV market that lasts for two periods. Importantly, each TV station is fully informed about its own as well as its rival's program. Viewers receive information via tune-ins, if any, or alternatively by sampling a program for a few minutes (and switching across stations). I find that equilibrium tune-in decisions do not necessarily depend on TV stations' knowledge of their rival's program. In this case, the opportunity costs of tune-ins could be so high that a regime without any tune-ins may be socially better. However, when tune-ins depend on both of the upcoming programs, it is possible that they enhance welfare by helping viewers avoid some of the inefficient program sampling they would otherwise do in a regime without any tune-ins

A More General Framework to Analyze Whether Voluntary Disclosure is Insufficient or Excessive

I analyze if the excessive quality disclosure finding of the “classical literature” extends to environments in which consumers have a downward-sloping demand. While the answer is affirmative, there are at least two situations under which disclosure is socially insufficient: (1) when there are quality levels that are too low to generate any positive demand; and (2) when the prior beliefs place sufficiently higher weight on lower qualities. In both cases, non-disclosure by the seller leads to a severe reduction in the perceived quality, thereby significantly lowering the demand and the quantity consumed

Opaque Selling

We study “opaque” selling in multiproduct environments – a marketing practice in which sellers strategically withhold product information by keeping important characteristics of their products hidden until after purchase. We show that a monopolist will always use opaque selling, but it is not first-best optimal to do so. However, opaque selling might be used at the constrained optimum (with the monopolist’s pricing behavior taken as given). For linear disutility costs, it is optimal for a monopolist to offer a single opaque product

Product line design

We characterize the product line choice and pricing of a monopolist from the upper envelope of net marginal revenue curves to the individual product demand functions. The equilibrium product line constitutes those varieties yielding the highest upper envelope. In a generalized vertical differentiation framework, the equilibrium line is exactly the same as the first-best socially optimal line. These upper envelope and first-best optimal line findings extend to symmetric Cournot oligopoly

When Is It Optimal to Delegate: The Theory of Fast-Track Authority

With fast-track authority (FTA), the US Congress delegates trade-policy authority to the President by committing not to amend a trade agreement. Why would it cede such power? We suggest an interpretation in which Congress uses FTA to forestall destructive competition between its members for protectionist rents. In our model: (i) FTA is never granted if an industry operates in the majority of districts; (ii) The more symmetric the industrial pattern, the more likely is FTA, since competition for protectionist rents is most punishing when bargaining power is symmetrically distributed; (iii) Widely disparate initial tari§s prevent free trade even with FTA

Fluid Flows of Mixed Regimes in Porous Media

In porous media, there are three known regimes of fluid flows, namely, pre-Darcy, Darcy and post-Darcy. Because of their different natures, these are usually treated separately in literature. To study complex flows when all three regimes may be present in different portions of a same domain, we use a single equation of motion to unify them. Several scenarios and models are then considered for slightly compressible fluids. A nonlinear parabolic equation for the pressure is derived, which is degenerate when the pressure gradient is either small or large. We estimate the pressure and its gradient for all time in terms of initial and boundary data. We also obtain their particular bounds for large time which depend on the asymptotic behavior of the boundary data but not on the initial one. Moreover, the continuous dependence of the solutions on initial and boundary data, and the structural stability for the equation are established.Comment: 33 page
