| With some agri-environmental restrictions, municipal wastewater can be utilized for agricultural irrigation and river rehabilitation. This paper develops a single-year planning model for a region in Israel which consists of a city and three potential wastewater consumers. The model incorporates, in one endogenous system, the economic, physical and biological relationships in the water-soil-plant environment system and its objective is to maximize the regional social welfare composed of the sum of agricultural and environmental net benefits. The model determines the optimal crop mix and the optimal allocation of the limited water and land resources among all potential users. Then, different allocation approaches from the concept of transferable utility... |

| This study examines the optimal allocation of funds between national and urban parks. Since travel costs to national parks are significantly higher than to urban parks, poor households tend to visit the latter more frequently, whereas rich households favor the former. Therefore, allocating public funds to improving the quality of national parks at the expense of urban parks disproportionately benefits high income households. By developing a theoretical model and implementing it using Israeli data, findings indicate all households, except for the richest decile, prefer that the park authority divert a larger proportion of its budget from national to urban parks. |

| This paper investigates the effects of first-best policies to regulate nitrogen application. Some nitrogen fertilizer is applied ex ante before a random rainfall, but sidedressed nitrogen may be applied ex post. First-best policy is a tax or a quota on ex ante application, because sidedressed nitrogen is not leached. Since a risk-averse farmer uses more nitrogen ex ante than a risk-neutral farmer, a higher tax must be imposed on the former. Action equivalent first-best taxes and quotas are also welfare equivalent. An empirical model for wheat in Israel was used to demonstrate the analytical findings. |

| The economic implications of plant density for irrigation water use under saline conditions are investigated, utilizing the involved physical and biological relationships. The analysis considers a single crop and is applied to cotton data. The results suggest that treating plant density as an endogenous control variable has substantial impact on profits and the optimal quantities and qualities of the applied irrigation water. |

| In order to stimulate organic farming governments generally use a mix of temporary hectare payments and provision of public services for stimulating the development of the organic sector. In this paper a conceptual model is developed for determining a socially optimal hectare payment for any given level of public services. Farm heterogeneity, due to the variability of soil quality and management skills, is explicitly taken into account. Using an n-th price auction mechanism farmers indicate what their reservation subsidy is for a given level of public input provision. The outcome of this problem is utilized in the government's optimization problem. We found that the level of per hectare socially optimal subsidy increases significantly with the elasticity... |

| The study is focused on the development and the application of a stochastic economic optimisation model by which optimal levels of applied water and sprinkler spacing are determined. Data on crop-water production function and uniformity of water application are taken from a sprinkler irrigation plot of sweet corn. It was found that a saving of irrigation water can be achieved not only by raising water prices but also by increasing application uniformity. |

| The risk premium and the probability premium are used to determine appropriate coefficients of absolute risk aversion under CARA utility. A defensible range of risk aversion coefficients is defined by the coefficients that correspond to risk premiums falling between 1 and 99% of the amount at risk or to probability premiums falling between .005 and .49 for a lottery that pays or loses a given sum. The consequences of ignoring risk premiums when selecting risk-aversion coefficients for representative decision makers are illustrated by calculation of the implied risk premium associated with the levels of absolute risk aversion assumed in six selected studies. |

| Uncertainty about the possibility of acquiring land can be rather large in the EU for sectors like dairy farming. Farm-level investment decisions are commonly made ex-ante when the farmer is not certain about the possibility of purchasing land. This possibility is realized only in a future period. In this paper, we have developed and applied a simple two-period model in which a profit-maximizing farmer, facing uncertainty about the possibility of acquiring land, had to choose the optimal mix of capital (buildings) investment and land endowment. We have shown that commonly "observed" biases towards non-optimal investment decisions are not necessarily justified. Rather, these perceived biases may be the result of evaluating investment decisions without... |

| The impact of uncertain salt balances in irrigate fields is assessed with a hydroeconomic model that incorporates the effects of salinity. Uncertainty in two parameters that jointly determine root zone salinity is investigated and the conclusions prove to depend upon the way in which these parameters enter the mass-balance equation for soil salinity. It is shown that water has a risk reducing marginal effect on output when growers are risk averse and, under certain conditions, when they are risk neutral. The effects of prices, water quality, and crop salt sensitivity on the conclusions are analyzed and an empirical example is employed to illustrate the magnitude of the impacts. |
