In recent years, significant structural and production system changes have been noted in the U.S. and European Union, as well as increased interest in pasture-based dairy systems. Technical efficiency, returns to scale, and farm characteristics are compared by size and production system in...

If the output market is perfectly competitive and the firm’s production function is not concave, an increase in the output price may lead to an explosive increase in firm’s profits at some point. We explore the properties of this point, called a threshold price. We derive the formula for the...

In the whole world there are strong discussions on how to yield a more equitable access and a more efficient provision. One issue linked to efficiency is the achievement of scale economies in the industry, and the optimal dimension of water and sanitation providers. Changes in the industrial...

This article provides a theoretical framework related to Data Envelopment Analysis (DEA) in which an analytical relationship among eight different efficiency concepts is defined and explored in terms of production and cost analyses. This article extends the theoretical basis into the measurement...

This paper compares inferences about hospital cost and production correspondences from two different estimation models: (1) the econometric modeling of the translog cost function, and (2) the application of Data Envelopment Analysis (DEA). While there are numerous examples of the application of...

The reduced form approaches that are commonly adopted in the literature to model emission-generating technologies (EGTs) do not distinguish between emission-causing and non-emission causing goods in production. We provide a new set of axioms to describe EGTs. Technologies that satisfy these...

It has been suggested in the data envelopment analysis (DEA) literature that it is impossible to obtain a full ranking of decision-making units (DMUs) when infeasible subproblems arise in the so-called super-efficiency DEA models under different returns to scale (RTS) assumptions other than...

This paper examines two important issues related to bank mergers in India. First, we estimate potential economic gains of state-owned banks from consolidation. Scale economies, returns to scale and profit efficiency of state-owned banks during 1986 to 2007 are estimated based on stochastic...
