In this study, yield-water and profit function was used to obtain water demand function in agriculture sector. The results showed that the ratio of actual to potential Evapotranspiration had positive, significant effecton the ratio of actual to potential yield for wheat and barley. Also, square ratio of actual to potential Evapotranspiration had negative, significant relationship. After estimat...

Academic research in the €eld of recommender systems mainly focuses on the problem of maximizing the users’ utility by trying to identify the most relevant items for each user. However, such items are not necessarily the ones that maximize the utility of the service provider (e.g., an online retailer) in terms of the business value, such as pro€t. One approach to increasing the providers’ utili...

Recent natural gas price increases have resulted in acutely higher fertilizer prices. Profit and environmental concerns have increased interest in identifying optimal nitrogen application rates. Previous estimates of the profit maximizing nitrogen rate (PMNR) have been estimated assuming that price is fixed and exogenous of yield. We construct a model in which price is correlated to yield shock...

Manufacturers launch new product models at various time increments to meet changing market requirements over time. At each design period, product design and price may change. While price decisions can be made at product launching time, redesign decisions must be made in advance. Real options theory addresses such time gap decisions. This paper presents a real options approach with a binomial la...

OBJECTIVE To estimate the effects of changes in Medicare inpatient hospital prices on hospitals' overall revenues, operating expenses, profits, assets, and staffing. PRIMARY DATA SOURCE Medicare hospital cost reports (1996-2009). STUDY DESIGN For each hospital, we quantify the year-to-year price impacts from changes in the Medicare payment formula. We use cumulative simulated price impacts ...

We study the bidding behavior of spiteful agents who, contrary to the common assumption of selfinterest, maximize the weighted difference of their own profit and their competitors’ profit. This assumption is motivated by inherent spitefulness, or, for example, by competitive scenarios such as in closed markets where the loss of a competitor will likely result in future gains for oneself. We der...

in some situations the producers desire to maximize total profit of decision making units (dmus) while the inputs and outputs prices of dmus change from one time period to another. in this paper, the researchers develop productivity index when producers are going to maximize total profit when the price of inputs and outputs are known.the proposed method uses all price information about inputs a...

one of the main factors affecting on the technical and economic performance of farms and livestock is the ability or capacity management. main goal of farm management is achieving specific performance, profitability and productivity; there for measurement management and performance in livestock farms are necessary. considering the necessity of increasing production and quality in the dairy indu...

The competitive price game model is used to analyze the spectrum sharing in the cognitive radio networks. This paper focuses on the improved spectrum sharing problem with constraints of available spectrum resource from primary users. The constrained spectrum sharing model based on competitive price game is established. In order to achieve the spectrum sharing strategy that satisfies the constra...
