This paper investigates some applications of high-resolution, three­ dimensional PC-based computer graphics to research and education in agricultural production economics. Examples illustrate issues in the identification of stages of production for the multifactor case; special cases in which...

Much of the theory of the firm in product space is not nearly as well developed as the theory of the firm in factor space. For example, both general and agricultura1 economists have devoted considerable effort to developing functional forms representing production processes in factor space, but...

An econometric analysis of productivity convergence in Norwegian salmon aquaculture is undertaken. We also test for the effects of learning and external industry infrastructure capital. Empirical evidence for reduction in productivity differentials is found, but the estimated models also provide...

Low soil fertility is a major concern in agricultural productivity and development policy discourse in sub-saharan Africa. The problem is exacerbated by government withdrawal from fertilizer input markets and the inability of private sector operators to fill the gap. This warranted a search for...

In my research I have analysed the agricultural co-operative animal breeding and animal produce characteristics of four Mid Szigetköz villages (Ãsványráró, Hédervár, Darnózseli and Püski) from 1990 to 2006. I began my search with agricultural research, by examining the documents and...

This study examines three alternative models of correcting for heteroskedasticity in wheat yield: the time trend variance, the GARCH, and an econometric model that includes the potential sources of heteroskedasticity. Nonnested test results suggest that modeling the sources of heteroskedasticity...

This paper examines the Multi-Product Asymptotically Ideal Production Model as an alternative to the translog and normalized quadratic functional forms using farm level data. Factors such as ease of estimation, imposition of regularity conditions, and quantitative differences in empirical...

This paper examined cost efficiency differences between rural hospitals participating in the Critical Access Hospital (CAH) Program and a group of non-converting, prospectively paid rural hospitals using both a two-stage semi-parametric approach as well as stochastic frontier analysis (SFA)....
