| We extend Weitzman's (1998) recombinant growth framework to include endogenous R&D decisions. The analysis is carried out in the (knowledge-capital) state space by means of two characteristic curves: one is identified as a turnpike along which growing economies evolve; the other attracts stagnating economies. Sustained growth depends on a condition relating the slopes of the characteristic curves as well as on a minimal endowment requirement. A growing economy reaches the turnpike at a most rapid R&D rate and evolves along it thereafter. In the long run, the rate of growth and the income shares devoted to R&D, saving and consumption approach constant values that depend on the asymptotic characteristic slopes. |

| The economic value of energy storage to meet peak electricity demand is analyzed with an emphasis on the role of demand uncertainty. The concept of the stabilization value, which measures that part of the benefit of the storage project which is due solely to the stochastic demand components, is defined. The magnitude of the stabilization value, relative to the overall value of energy storage, is evaluated in terms of a simple model that accounts for the relevant characteristics of the electric power utility's production mix. It is found that neglecting the demand uncertainty can seriously bias the benefit assessment of the storage project as well as the determination of the optimal storage capacity. |

| We study the management of a natural resource that supports ecosystems as well as human needs. The reduction in the resource base introduces a threat of occurrence of catastrophic ecological events, such as the sudden collapse of the national habitat that lead to severe loss of biodiversity. The event occurrence conditions involve uncertainty of various types, and the distinction among these types affects the optimal exploitation policies. When uncertainty is due to our ignorance of some aspects of the underlying ecology, the isolated equilibrium states characterizing optimal exploitation for many renewable resource problems become equilibrium intervals. Events triggered by genuinely stochastic environmental conditions maintain the structure of... |

| Groundwater resources (GW) account for nearly 30 percent of the world sustainable water supplies. Yet, this resource, which is fraught with externalities, has largely been left unregulated. The economic literature on GW is predominantly of a partial equilibrium type, taking the rest of the economy parametrically. We analyze GW regulation in a general equilibrium setting, focusing on the stabilization value of GW under natural (draught) and economic (rural-urban water transfer) shocks. A general equilibrium approach allows evaluating direct and indirect effects of GW regulation on agriculture and non-agriculture sectors and extends the scope for water policy. The analysis is applied to Morocco by extending an existing computable general equilibrium (CGE)... |

| We propose procedures for testing statistically the significance of violations of nonparametric tests of optimization axioms when observed behavior is measured with error. The tests are robust against parametric specification of the error distribution, thus are nonparametric in both the statistical and economic senses, and are readily implemented numerically. An illustration with demand data is presented. |

| Water policy is prone to error because of the complexity of irrigated agriculture. Agriculture is spatially dependent, it exists in the context of a nation's economy with which it must compete for resources, and water markets seldom exist. The process of collective action, as Douglas North has noted, typically involves a process that places emphasis on the direct effects of a policy outcome. The constraints of collective action tend to be such that this process is not capable of "solving" the simultaneous equations of a real economy as a decentralized market mechanism can be characterized as being able to perform. The contribution of the paper is to measure the direct and indirect effects of irrigation water policy in an economy-wide context for the case... |
