The paper presents an analysis of the wheat yields variability in voivodeships of Poland. The main aim of the study is to present several possible indicators for the crop variability in the context of production risk. It is found that ignoring the long-term yield trends leads to a serious...

In this paper, we assess the potential for rehabilitation of comparative analysis under its new guise of benchmarking. After a brief description of comparative analysis, we discuss the deficiencies that surrounded its fall in reputation: neglect of economic principles, limited scope for action,...

This paper analyzes the sequential decision to adopt two site-specific technologies, soil testing and variable rate technology (VRT), and their impact on nitrogen productivity in four Midwestern states. The results indicate that while farm location was a key variable influencing the adoption of...

The conventional computational algorithms for full information maximum likelihood (FIML) estimation of the censored probit model (see Farber, 1983), will sometimes fail to converge when the estimated value of the correlation coefficient (ñ) approaches ±1; even when the true value of ñ is not...

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...

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...

The interconnections of agriculture and energy markets have increased through the rise in the new biofuel agribusinesses and the oil–ethanol–corn linkages. The question is whether these linkages have a causal structure by which oil prices affect commodity prices and through these links,...

The volatility of agricultural markets has increased remarkably in recent years. In spite of this, the way in which supply chain actors perceive market volatility has only rarely been analyzed. This paper seeks to close this research gap by presenting empirical findings about how the volatility...

The importance of organizational issues to assess the success of international development project has not beenfully considered yet. An analysis of the literature on the project success definition, focused on the successcriteria and success factors, was carried out by surveying the contribution...
