This paper explores how Knightian uncertainty affects dynamic properties in an economic growth model. The decision-making theory employed in the analysis is the theory of expected utility under a non-additive probability measure, i.e., the Choquet expected utility model of preference. We apply...

We examine a simple theory of altruism in which players' payoffs are linear in their own monetary income and their opponents. The weight on the opponent's income is private information and varies in the population, depending, moreover, on what the opponent's coefficient is believed to be. Using...

New technology embodied in capital equipment can be adopted either through destruction of existing jobs and the creation of new ones or by renovation, updating the job's equipment. Under the assumption that the destruction of jobs generates worker layoffs, we show that higher productivity growth...

Building on evidence that (a) productivity growth from learning by doing diminishes as experience accumulates with a technology and (b) learning by doing is largely specific to each production technology, this paper models a firm's decision of when to update its technology. The model implies...

Financial frictions distort the allocation of resources among productive units--all else equal, firms whose financing choices are affected by such frictions face higher borrowing costs than firms with ready access to capital markets. As a result, input choices may differ systematically across...

We study the problem of an investor that buys an equity stake in an entrepreneurial venture, under the assumption that the former cannot monitor the latter's operations. The dynamics implied by the optimal incentive scheme is rich and quite different from that induced by other models of repeated...

We develop a dynamic general equilibrium model to study the impact of the 2003 dividend and capital gains tax cuts. In the model, firms are heterogeneous in productivity and make investment and financing decisions subject to capital adjustment costs, equity issuance costs, and collateral...

Credit supply and demand changes are mostly unobserved, thus identifying completely the transmission of monetary policy through the credit channel is unfeasible. Bank lending surveys by central banks, however, contain reliable quarterly information on changes in loan conditions due to bank, firm...

This paper introduces Heckscher-Ohlin trade features into a two-country dynamic stochastic general equilibrium model, and studies the international transmission of productivity shocks through trade in goods. This framework improves upon existing international real business cycle models in that...

This paper develops a real business cycle model characterized by idiosyncratic employment shocks and quantitatively explores the behavior of aggregate variables under the assumptions of complete and incomplete insurance markets. The results show that the model with incomplete markets produces...
