Children's crusade

There's at least $16 billion available to help more children get health care. But on Capitol Hill, there's a bitter dispute over how the money should be spent. Give the states the money, some say, and let them bolster novel health care programs such as Florida's Healthy Kids. Others want to expand Medicaid.     

Why Democracies Cooperate More and Fight Less: The Relationship Between International Trade and Cooperation

This paper provides an economics-based interpretation of the standard finding in the literature that democracies rarely fight each other. A general theory of conflict between two countries is presented and empirical analysis applies this theory to the question of why democracies rarely fight each other. The results show that the fundamental factor in causing bilateral cooperation is trade. Countries seek to protect wealth gained through international trade, therefore trading partners are less combative than nontrading nations. Democratic dyads trade more than nondemocratic dyads, and thus exhibit less conflict and more cooperation.     

An experimental study of strategic information transmission

Summary We examine strategic information transmission in an experiment. Senders are privately informed about a state. They send messages to Receivers, who choose actions resulting in payoffs to Senders and Receivers. The payoffs depend on the action and the state. We vary the degree to which the Receivers' and the Senders' preferences diverge. We examine the relationship between the Senders' messages and the true state as well as that between actions and the true state and contrast the ability of different equilibrium message sets to explain the data.When preferences are closely aligned Senders disclose more. We assess two comparative statics: (i) as preferences diverge, state and action are less frequently matched, and (ii) messages tend to become less informative as preferences diverge. The first result is weakly confirmed for adjacent treatments but is considerably stronger when non-adjacent treatments are compared. We find that as preferences diverge messages become less informative. While the ex-ante Pareto-optimal Bayesian Nash Equilibrium does not explain our conditions, the equilibrium message sets supported by the data are similar to the ex-ante Pareto Optimal message sets.We would like to thank seminar participants at the Economic Science Association meetings, the University of Iowa, the University of Minnesota, Northwestern University and the Society for the Advancement of Economic Theory meetings for their comments.

The maintenance, funding and modification of retiree medical benefits

Retiree medical benefits are an ever-growing concern as costs escalate and the date for implementation of Statement of Financial Accounting Standards No. 106 approaches. These authors summarize case law relevant to employers' right to modify or terminate benefits and discuss methods of funding theses liabilities.     

The Effect of Respondent Experience/Knowledge in the Elicitation of Contingent Values: An Investigation of Convergent Validity,Procedural Invariance and Reliability

Tests of convergent validity and procedural invariance were used to investigate whether individuals lacking direct experience with a commodity can provide valid responses to contingent-valuation questions eliciting ex post use values. Convergent validity between samples with and without experience was shown to hold for dichotomous-choice responses, but not for open-ended responses.     

On the convergence of reinforcement learning

This paper examines the convergence of payoffs and strategies in Erev and Roth's model of reinforcement learning. When all players use this rule it eliminates iteratively dominated strategies and in two-person constant-sum games average payoffs converge to the value of the game. Strategies converge in constant-sum games with unique equilibria if they are pure or if they are mixed and the game is 2×2. The long-run behaviour of the learning rule is governed by equations related to Maynard Smith's version of the replicator dynamic. Properties of the learning rule against general opponents are also studied.     

The Role of Fiscal Policy in the Eighties*

After surveying objections to using expansionary fiscal policy to raise output and employment. this article concludes that budget deficits do not necessarily lead to high interest rates and that crowding out is only moderate. even with non-accommodating monetary policy. The major constraint on the effectiveness of expansionary fiscal policy is the need to avoid devaluation. If real wages are rigid downwards. devaluation will lead to increases in inflationary pressure rather than increases in output. Because of this. and because of inflationary pressure from short-run Phillips curve effects. expansionary fiscal policy must be complemented by a prices and incomes policy.
