The modern queens maintenance systems are based on the use of artificial insemination, queens’ maintenance in the so called „queens bank” , in this way assuring an increased economic efficiency in beekeeping. This study aimed to compare the economic efficiency of the implementation of A.I. to various queen bees maintenance systems. Three alternatives have been taken into account: V1-a queen bee...

Influence maximization is a problem of finding a small set of highly influential individuals in social networks to maximize the spread of influence. However, the distinction between the spread of influence and profit is neglected. The problem of profit maximization in social network extends the influence maximization problems to a realistic setting aiming to gain maximum profit in social networ...

Submitted: Jun 12, 2013; Accepted: Jul 23, 2013; Published: Jul 25, 2013 Abstract: Companies around the world normally assign a portion of their benefits to their employees. This policy is used as an encouragement to increase the motivation of employees. If the profit sharing seems unfair, its expected results will be lost. In this paper, a model is developed to determine a desirable profit sha...

We develop a (noncooperative) game theoretic model for a decentralized setting wherein fringe farmers compete with a two-tier cooperative network involving network farmers and a coordinator. We examine the roles of the coordinator and profit sharing in allocating costs/benefits of externalities in enhancing network efficiency and stability. Our main finding is that using profit sharing based me...

We offer a unified framework to analyze the determination of employment, employee effort, wages, profit sharing and capital structure when firms face stochastic revenue shocks. We apply a generalized Nash bargaining solution, which extends the wage bargaining literature by incorporating efficiency wage considerations, profit sharing and capital structure. The profit sharing instrument is demons...

In perfectly competitive markets, prices aggregate inputs and outputs into a money metric that allows production plans to be ranked by their profitability. When informational asymmetries in competitive markets lead to adverse selection, prices in these markets assume an additional role that conveys information about product quality. In the case of banking production, quality is linked to risk b...

The technical and allocative efficiency of broadacre farmers in a southern region of Western Australia is investigated over a three-year period. Applying data envelopment analysis (DEA) and stochastic frontier analysis (SFA) reveals there is some inefficiency in each year, which decreases over time. The distributions of technical efficiency in each year are positively skewed toward higher effic...
