In this paper, charity is considered as a strategic selfish activity that increases the welfare of the contributors without altruism. The model supposes the interactive simultaneous utility maximization of two consumer groups, contributors and recipients, who share the same utility function but...

Using a general equilibrium framework, this paper analyzes the equilibrium provision of a pure public bad commodity (for example pollution). Considering a finite economy with one desired private good and one pure public “bad” we explicitly introduce the concept of Lindahl equilibrium and the...

Lindahl and Nash equilibria are often used in the theory of public good. Shitovitz and Spiegel (1998) present an example of 2-person economy with one private good and one pure public good, where the core efficient Lindahl allocation does not Pareto dominate the (inefficient) Nash allocation. In...

This paper studies the provision of a public good via voluntary contributions in an economy with uncertainty and differential information. Consumers differ in their private information regarding their future endowment as well as in their preferences. Each consumer selects her consumption ex...

This paper addresses an important and underresearched issue in the economics and marketing literatures: what are the managerial and social consequences when firms use business models that are based on the dissemination of free samples? We develop an analytical model of free samples for both...

This paper proposes a transactions cost theory of total factor productivity. In a world with asymmetric information and transactions costs, effort, and thus productivity, must be induced by incentive schemes. Labor contracts trade off the marginal benefits and the marginal costs of effort. The...

This note demonstrates that it is easily possible to compute technological parameters out ot national income acconting data in the presence of bargaining in the labor market. Applying the method to US data, we obtain that the output elasticity with respect to capital exceed 0.5.
