A vivid debate is ongoing in the scientific community about statistical malpractice and the related publication bias. No general consensus exists on the consequences and this is reflected in heterogeneous rules defined by scientific journals on the use and reporting of statistical inference. This paper aims at discussing how the debate is perceived by the agricultural economics community and implications for our roles as researchers, contributors to the scientific publication process, and teachers. We start by summarizing the current state of the p-value debate and the replication crisis, and commonly applied statistical practices in our community. This is followed by motivation, design, results and discussion of a survey on statistical knowledge and practice among the researchers in the agricultural economics community in Austria, Germany and Switzerland. We conclude that beyond short-term measures like changing rules of reporting in publications, a cultural change regarding empirical scientific practices is needed that stretches across all our roles in the scientific process. Acceptance of scientific work should largely be based on the theoretical and methodological rigor and where the perceived relevance arises from the questions asked, the methodology employed, and the data used but not from the results generated. Revised and clear journal guidelines, the creation of resources for teaching and research, and public recognition of good practice are suggested measures to move forward.

In this article the authors provide an economic assessment of the technology of using unmanned aircraft systems in digital agriculture and justify the optimal requirements for its main technological parameters. As a measure of comparative evaluation of various options for implementing the system, an estimate of the cost of performing the technological process of using pesticides, fertilizers and other agrochemicals in conditional price units is proposed. A multi-factor experiment was carried out and variants of a mathematical model describing the relationship between agrotechnological factors and the final resultant, expressed in the conditional cost of processing 1 Ha of agricultural land, were obtained. The optimal values of the parameters are obtained for various variants of fixing factors at the specified levels. The influence of the most significant agrotechnological factors on the cost of the technological process of using pesticides, fertilizers and other agrochemicals is shown. The values of factors that should be used in the development of new types of unmanned aerial vehicles to ensure their maximum demand in agriculture and economic efficiency are proposed.

“…Gelman (2013), among others, argue that quantitative social scientists should not be particularly worried about committing Type I errors. Rather, we should be more concerned about Type S errors, getting the sign right, and Type M errors, getting the magnitude right (Gelman & Tuerlinckx, 2000;Rommel & Weltin, 2020;Ziliak & McCloskey, 2008). Pre-analysis plans are less useful in combating these type of errors.…”

Economists have recently adopted pre-analysis plans in response to concerns about robustness and transparency in research. The increased use of registered pre-analysis plans has raised competing concerns that detailed plans are costly to create, overly restrictive, and limit the type of inspiration that stems from exploratory analysis. We consider these competing views of pre-analysis plans, and make a careful distinction between the roles of pre-analysis plans and registries, which provide a record of all planned research. We propose a flexible "packraft" pre-analysis plan approach that offers benefits for a wide variety of experimental and nonexperimental applications in applied economics.
