| The theory of stock uncertainty in the utilization of exhaustible resources is extended to renewable groundwater resources. A complete characterization of the exploitation process is presented, paying special attention to the formulation of the trasversality conditions. Exploration activities are incorporated and fit smoothly within the framework of analysis. Extensions to other renewable situations are outlined. |

| 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. |

| A constant social discount rate cannot reflect both a reasonable opportunity cost of public funds and an ethically defensible concern for generations in the distant future. We use a model of hyperbolic discounting that achieves both goals. We imbed this discounting model in a simple climate change model to calculate “constant equivalent discount rates” and plausible levels of expenditure to control climate change. We compare these results to discounting assumptions and policy recommendations in the Stern Review on Climate Change |

| Understanding the allocation of labor between collective and private activities within cooperatives has been an issue of interest for economists and policy makers. This paper extends existing literature by incorporating income uncertainty from both private and collective activities, and by assuming that members are risk averse. The analysis suggests a member's labor response to policy parameters can be decomposed into three components: the mean effect, reflecting the labor response under certainty or risk neutrality; the variance effect, reflecting the response to changes in risk; and the wealth effect, reflecting the response to changes in risk aversion associated with changes in wealth. The analysis demonstrates the labor response may be reversed from... |

| When used in conjunction with surface water for irrigation, groundwater serves two roles: to increase water supply; and to mitigate fluctuations in the supply of water. The later is the buffer role. This paper identifies and evaluates the economic benefit associated with the buffer role of ground water. Implications for the development of groundwater resources are investigated. An estimate is given of the buffer benefit to wheat growers of the fossil water aquifer underlying the Israeli Negev. It is found that, under the prevailing variability in the supply of surface water, this benefit may well exceed the groundwater benefit associated with the increase in water supply. |

| This paper uses mechanism design theory to (i) propose a mechanism to price irrigation water when farmers are heterogeneous in their production technologies (adverse selection) and their individual water uses are unobserved (moral hazard) and (ii) discusses briefly when such a mechanism might be economically unreasonable. Unmetered irrigation water is often priced by imposing per-acre fees on cultivated acreage or by charging per-unit fees on observable inputs or outputs. The offered pricing procedure is based on the observed output and achieves a first-best outcome when implementation is free of transaction costs. |

| 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 study optimal adaptation to climate change when the harmful consequences of global warming are associated with stochastic occurrence of abrupt changes. The adaptation policy entails the accumulation of a particular sort of capital that will eliminate or reduce the catastrophic damage of an abrupt climate change when (and if) it occurs. The occurrence date is uncertain. The policy problem involves balancing the tradeoffs between the (certain) investment cost prior to occurrence and the benefit (in reduced damage) that will be realized after the (uncertain) occurrence date. For stationary economies the optimal adaptation capital converges to a steady state. For growing economies the optimal adaptation capital stock approaches the maximal economic level... |
