In long-term trials, not only are individual plot errors correlated over time but there is also a consistent underlying spatial variability in field conditions. The current study sought the most appropriate covariance structure of errors correlated in three dimensions for evaluating the...

An assessment of time-trends in yield parameters is essential to the utilization of data from long-term field trials for the comparison of different crop rotations and input regimes, and the identification of sustainable production systems. The barley-vetch rotation established at Breda in...

As an alternative to analyzing field data, our research utilizes controlled laboratory experiments with human decision makers and salient financial incentives. Within the laboratory, we determine (hence, know) the true tax liability, and then identify the effects of information services by...

This compilation of original papers selected from the 19th Conference on Postal and Delivery Economics and authored by an international cast of economists, lawyers, regulators and industry practitioners addresses perhaps the most significant problem that has ever faced the postal sector –...

To date there is limited knowledge of how having access to post-harvest storage technology affects a smallholder African farmer’s decision to adopt higher-yielding improved maize varieties. This is a key issue because higher yielding varieties are known to be more susceptible to storage pests...

Business and government leaders from around the world are increasingly sounding the alarm about the need for effective management of business dependencies and impacts on ecosystems. As a consequence, financial institutions have recently made a formal commitment to work towards integrating...

The common practice to calculate wind generation capacity values relies more on heuristic approximations than true system estimations. In this paper we proposed a more accurate method. In the first part of our analysis, a Monte Carlo simulation was created based on Markov chains to provide an...

Not-for-profit enterprises often rely on donors for operating funds. Through fund-raising campaigns, individual donations are solicited, and the successes of fund-raising campaigns depend on various features of the campaign. In this article, the authors use experimental methods to investigate...
