Concern is growing throughout the United States about environmental and health risks associated with the use of agricultural chemicals. In response to these concerns, public policies designed to alter farming practices and the use of agricultural chemicals are being proposed and implemented. In...

We examine the role of altruism in determining optimal transfers from a principal (a mother) to selfish agents (her children) in return for attention services. Transfer-attention contracts are studied in a setting in which informational asymmetries arise from the inability of a parent to...

Purpose – Enabling decision-makers in Israel to better assess the prospects of government policies aimed at changing inter-generation income distribution for the benefit of the retirees. Design/methodology/approach – Based on a comprehensive data set, the paper utilizes multivariate...

This paper develops and applies a mathematical model for determining the economically optimal scheduling of fertilization and irrigation (fertigation) that maximizes the farmer's profits. The analysis assumes a single crop (corn) and a single growing season. For a given total seasonal...

This paper develops a regional-level planning model aimed at allocating treated sewage sludge among potential users. The model incorporates, in one endogenous system, the economic, biological and environmental relationships and its objective is to maximize the regional social welfare. A few...

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...

The study investigates the value of additional information on the response function to soil salinity of a given crop (potatoes), with regard to a stochastic long-run optimization model for utilization of saline water to a single farm framework. The analysis provides a conceptual and...

The optimal long-run fertilisation and irrigation of a perennial crop is approached via two stochastic dynamic optimisation models. The first model assumes that the ex-post level of the state variable--leaf nitrogen (LN)--is known with certainty. The second model assumes that the level of leaf...

Investigates the split application of nitrogen for rainfed corn in the Midwest using two-stage decision model. Ex post analysis of late nitrogen application; Ex ante analysis of preplant nitrogen application: Use of information from the Erosion Productivity Impact Calculator (EPIC); Implications...
