A basic assumption in the economic literature is the one of diminishing marginal returns to labour. However, theoretical studies on knowledge and labour specialization assume that an increase in the knowledge investment embodied in the human capital of workers raises the marginal product of...

This paper investigates cost and profit efficiency of German hospitals. More specifically, it deals with the question how hospital efficiency varies with ownership, patient structure,and other exogenous factors, which are neither inputs nor outputs of the production process. We conduct a...

Rice cultivation is intensively cultivated in some regions of Costa Rica thanks to the establishment of several irrigation projects. This is especially important for the case of several agricultural communities that cultivate their land around the Palo Verde National Park, where the development...

Typically, firms change their size through a row of discrete leaps over time. A very basic model allowing for discontinuous growth can be based on a couple of assumptions: (a) in the short run, the firm’s equipment and organization provide the maximum profit only for a given production level,...

It 15 difficult to obtain c1osed-fonn solutions for input demand equations that are conducive to econometric estimation and policy analysis when the production function IS unknown Developments In the theory of duality facilitate obtaining such equations This article provides three examples of...

Recent changes in pricing policies emphasizing price supports and phasing out fertilizer subsidies are a step in the right direction, particularly if minimizing the combined foreign exchange and budgetary expenditures of Bangladesh and donor nations is the key objective. A normalized restricted...

This paper reconsiders the formal estimation of bank risk using the variability of the profit function. In our model, point estimates of the variability of profits are derived from a model where this variability is endogenous to other bank characteristics, such as capital and liquidity. We...

A theoretical model identified ranges of spatial variability required within multiple-land-class fields for economically viable variable rate technology (VRT) and the spatial variability required for maximum return to VRT. An example illustrated that return to VRT and the viable range of spatial...
