sugar beet as an industrial crop plays a main role in satisfying domestic demand of sugar. study on the production efficiency of sugar beet is important because this is a factor that influences production without additional cost. in this study, data envelopment analysis approach (dea), was implemented to calculate technical, administrative and scale efficiency of sugar beet production. also opt...

Economical and biological efficiencies of beef production to weaning and to slaughter were estimated in three groups, different in milk available (low, medium, and high) to the calves but with the same potential for growth. Data from different breed groups of cows (low [L] = Hereford x Angus, medium [M] = Red Poll x Angus, and high [H] = Milking Shorthorn x Angus) were used. Economical efficien...

Over the last decade, outsourcing has proved to be a relevant strategic option for companies narrowing their operations to focus on core competencies. This paper analyses the process of outsourcing manufacturing to cost-efficient and innovative suppliers in support of internal resources and capabilities. A scientific reference model founded on manufacturing strategy is proposed to help choose t...

Efficiency is a term used to describe producing a product with the least amount of waste. Waste on beef cattle ranches typically involves waste of time, labor, financial resources and natural resources. To become more efficient, beef cattle producers must me...

This paper proposes a two-dimensional efficiency decomposition (2DED) of profitability for a production system to account for the demand effect observed in productivity analysis. The first dimension identifies four components of efficiency: capacity design, demand generation, operations, and demand consumption, using Network Data Envelopment Analysis (Network DEA). The second dimension decompos...

A pillage game is a formal model of Hobbesian anarchy as a coalitional game. The technology of pillage is specified by a power function that determines the power of each coalition as a function of its members and their wealth. A coalition can despoil any other coalition less powerful than itself. The present paper studies the problem of achieving an efficient allocation of resources when the re...

This paper has two main purposes. Firstly, we develop various ways of defining efficiency in the case of multiple-output production. Our framework extends a previous model by allowing for nonseparability of inputs and outputs. We also specifically consider the case where some of the outputs are undesirable, such as pollutants. We investigate how these efficiency definitions relate to one anothe...

Speaking is generally considered efficient in that less effort is spent articulating more redundant items. With efficient speech production, less reduction is expected in the articulation of phonemes that are more important (distinctive) for word identification. The importance of a single segment in word recognition can be quantified as the information (in bits) it adds to the preceding word on...

We study a 2-sided matching market with a set of heterogeneous firms and workers in an environment where jobs are secured by regulation. Without job security Kelso and Crawford have shown that stable outcomes and efficiency prevail when all workers are (weak) gross substitutes to each firm, in the sense that increases in other workers’ salaries can never cause a firm to withdraw an offer from a...
