Remote retrieval of near-surface chlorophyll-a (Chla) concentration in small inland waters is challenging due to substantial optical interferences various water constituents and uncertainties the atmospheric correction (AC) process. Although algorithms have been developed estimate Chla from moderate-resolution terrestrial missions (∼10–60 m), production both accurate distribution maps time seri...

The dominance in neo-classical economic teaching of the concept of a production function, in which the relative prices of the factors of production are exhibited as a function of the ratio in which they are employed in a given state of technical knowledge, has had an enervating effect upon the development of the subject, for by concentrating upon the question of the proportions of factors it ha...

the quality of firms’ reaction against demand uncertainty affects the production inputs employment. in this research i have studied and compared the behavior of active firms in manufacturing sector with respect to the risk attitude and tested it’s effect on production inputs combination(with the special emphasize on labor employment). the research findings reveal that active firms in manufactur...

In the model where the choice of technology by firms endogenously determines productivity differences, we investigate the link between factor endowment and the productivity both in the firm and industry levels. We find among others that firms in capital-abundant countries tend to adopt new advanced technologies more in their production processes, but opening to international trade will equalize...

This paper analyses the general equilibrium effects on asset valuation and capital accumulation of an exogenous drop in the rate of return required by investors in a model of production with imperfectly competitive product markets. The model improves substantially on the standard perfectly competitive neo-classical framework, by dissociating the behavior of marginal and average q. It tracks mor...

This paper estimates a translog stochastic frontier production function in the analysis of all 48 contiguous U.S. states in the period 1970-1983, to attempt to measure and explain changes in technical efficiency. The model allows technical inefficiency to vary over time, and inefficiency effects to be a function of a set of explanatory variables in which the level and composition of public capi...

Employing data on over 100 GCC banks for 1996e2011, we test the relation between risk and capital. Given the interlinkage between these two variables, the model employs a 3SLS estimation that takes on board this simultaneity. Consistent with the literature, risk is measured by the Z-score, while capital is computed as the ratio of equity to asset. The findings indicate that banks generally incr...
