We develop a simple life cycle model with endogenous longevity where religious firms influence religious beliefs using donations as an input. The model suggests that either wealth and economic development or competition by religious firms can explain cross-country variation in religious beliefs,...

We develop a simple analytical framework where the longevity of profit-maximizing firms requires costly resources. We show that a firm's longevity and value are positively related to the firm''s pricing power, cash reserves, honesty, and ratio of equity to debt financing.

The welfare costs of dynamic factor taxes are analyzed in a dynamic general equilibrium model with heterogeneous endowments, abilities, and tastes. Conventional functional form restrictions yield formulas for the transition effects and marginal welfare costs of factor taxes. Heterogeneity...

Many existing theories of financial intermediation have difficulty explaining why financial activity can generate large real effects. This paper argues that the large real effects may reflect a multiplicity of equilibria. The multiple equilibria in this paper are generated by the dynamic...
