| This paper discusses basic issues in project analysis and shows how these issues can be resolved in a computable general equilibrium (CGE) framework. The role of border prices and intersectoral linkages is explored. The CGE framework is compared to less comprehensive frameworks, including benefit-cost analysis, input-output models, multi-market models, and models based on social accounting matrices (SAMs). An illustrative CGE model of the southern portion of the San Joaquin Valley is constructed and is used to find the effects of reducing water inputs on aggregate Valley gross domestic product (GDP) and on sectoral output, employment, and land use. The model is also used to determine demand curves for water by the southern portion of the Valley, given... |

| Rent dissipation in open access fisheries is a well studied problem (Gordon 1954; Homans and Wilen 1997). Regulation is seen as a possibly remedy to the externality of entry, which eventually leads to zero profits and depressed stocks. Despite regulation, drastic declines have occurred in many regulated fisheries worldwide, prompting a discussion of economic, biological, and environmental phenomena that may lead to declines. We explore one case when a regulator permits overfishing in the context of a traditional fishery model. Influenced by industry to reduce effort restrictions, regulators often rely on gear, season length, and other efficiency restrictions to achieve management goals. Under standard assumptions we find that when the regulator is... |

| How potential entrants to an open-access fishery form their expectations determines the fishery’s adjustment path to a steady state but not the steady state values themselves. It is well known that, in the standard model with myopic expectations (those based on current values), boats enter the fishery only when the fish stock is greater than its steady state stock. We show that, with rational expectations (perfect foresight), however, boats may enter when the fish stock is much lower than its steady state value if the boat fleet is sufficiently small. This paper contrasts myopic and rational expectations within a general dynamic model of an open-access fishery. |

| Funds available to purchase land and easements for conservation purposes are limited. This article provides a targeting strategy for protecting multiple environmental benefits that includes heterogeneity in land costs and probability of land-use conversion, by incorporating spatially explicit land-use change and hedonic price models. This strategy is compared to two alternative strategies that omit either land cost or conversion threat. Based on dynamic programming and Monte Carlo simulations with alternating periods of conservation and development, we demonstrate that the positive correlation between land costs and probability of land-use conversion affects targeting efficiency using parcel data from Sonoma County, California. |
