In this article, we show how to analyse analytically the equilibrium policies and prices in an economy with a stochastic investment opportunity set and incomplete financial markets, when agents have power utility over both intermediate consumption and terminal wealth, and face portfolio...

Discounted-cash-flow (DCF) techniques form the basis of most corporate-investment decisions. Many practitioners, however, claim to be dissatisfied with traditional methods of appraisal. In this paper, we survey DCF and more recent methods of evaluating cyclical projects.

Milton Friedman argued that irrational traders will consistently lose money, won't survive and, therefore, cannot influence long run equilibrium asset prices. Since his work, survival and price influence have been assumed to be the same. Often partial equilibrium analysis has been relied upon to...

We study an overlapping-generations economy in which new agents innovate and introduce new products and firms. Innovation is stochastic. The new firms increase overall productivity, but also steal business from pre-existing firms and act as depreciation shocks for the human capital of existing...

agents do not survive and do not affect prices in the long run. If relative risk aversion is unbounded, however, they may survive, and survival is neither necessary nor sufficient for their impact on prices. We provide necessary and sufficient conditions for price impact, as well as examples of...

We propose a simulation-based procedure for evaluating approximation accuracy of numerical solutions of general equilibrium models with heterogeneous agents. We measure the approximation accuracy by the magnitude of the loss suered by the agents as a result of following suboptimal policies. Our...

cross-section, a strategy that is long on durables and short on services earns a sizable risk premium. In the time series, a strategy that is long on durables and short on the market portfolio earns a countercyclical risk premium. We develop an equilibrium asset-pricing model that explains these...
