Are We Better Off If Our Politicians Have More Information?

This paper studies a model of public policy with heterogenous citizens/voters and two public goods: one (roads) is chosen directly by an elected policymaker, and the other (pollution) depends stochastically on the amount of roads. Both a one-country and a two-country version of the model are analyzed, the latter displaying externalities across the countries which creates incentives for free riding and strategic delegation. The welfare effects of providing the policymaker with information about the relationship between roads and pollution are investigated, and it is shown that more information hurts some – sometimes even all – citizens. In particular, the absence of an institution for information gathering can serve as a commitment device for a country, helping it avoid the free-riding problem. Implications for the welfare effects of “informational lobbying” are discussed.Public information acquisition, value of information, welfare, interest groups, informational lobbying, strategic delegation

Insisting on a Non-Negative Price: Oligopoly, Uncertainty, Welfare, and Multiple Equilibria

I study Cournot competition under incomplete information about demand while assuming that market price must be non-negative for all demand realizations. Although this assumption is very natural, it has only rarely been made in the earlier literature. Yet it has important economic consequences: (1) multiple (symmetric, pure strategy) equilibria can exist, despite the fact that demand and cost are linear; and (2) expected total surplus can be larger when the firms do not know demand than when they do, a result which has important implications for the social desirability of information sharing. The arguments of the paper are relevant also for price competition and for uncertainty about, e.g., cost or the number of firms, and these issues are discussed.

Lobbying, Information Transmission, and Unequal Representation

We study the effects of unequal representation in the interest-group system on the degree of information transmission between a lobbyist and a policymaker. Employing a dynamic cheap-talk model in which the lobbyist cares instrumentally about his reputation for truthtelling, we show that the larger is the inequality, the less information can credibly be transmitted to the policymaker. We also investigate the effects of inequality on welfare and discuss the welfare effects of institutions that increase transparency but which as well, as an unintended side-effect, lower the lobbyist's incentives for truthtelling.lobbying, interest groups, reputation, information transmission, representation, inequality, bias

Eliciting Demand Information through Cheap Talk: An Argument in Favor of Price Regulations

A firm must decide whether to launch a new product. A launch implies considerable fixed costs, so the firm would like to assess downstream demand before it decides. We study under which conditions a potential buyer would be willing to reveal his willingness to pay under different pricing regimes. We show that the firm's welfare -- as well as consumers' -- may be higher with a commitment to linear pricing than when pricing is unrestricted. That is, if informational asymmetries are significant, price regulations such as the Robinson-Patman Act may be endorsed by all parties.Price regulations, price discrimination, incomplete information, cheap talk, Robinson-Patman Act
