Improving the welfare of animals is an important aim in livestock farming. Thereby, farmers’ willingness to implement animal welfare practices directly influences the welfare of animals. Therefore, this paper investigates pig farmers’...

While many studies have compared the technical efficiency of part-time and full-time farms, we add to the existing literature by extending this analysis to scale efficiency. Based on a sample of crop farms in Austria between 2010 and 2017, we find...

Crop insurance adoption remains low among small and medium farms – despite financial public support in the form of premium subsidies. A better understanding of smaller farmers’ insurance decisions and contract attribute preferences is thus...

In this paper, we attempt to identify the major groups of decision making units (dairy farms) contributing to the aggregate efficiency change. We also suggest identifying influential peers in order to gain more insights into possible development...

Most research on false information is currently beeing conducted in the realm of politics and Covid-19. This study addresses environmentally-related news stories. With the help of two experiments, I explore determinants that can explain who is good...

This paper provides review about challenges and opportunities to assess and quantify market power in agricultural land markets. Measuring land market power is challenging because the characteristics of this production factor hinder the direct...

In this study, we explore the economic well-being of farm and nonfarm households in Germany. We applied an indicator that combines households' disposable income and net wealth consisting of financial assets and real estate to data from the Income...

We calibrate Linear and Mixed Integer Programs with a bi-level estimator, minimizing under First-order-conditions (FOC) conditions a penalty function considering the calibration fit and deviations from given parameters. To deal with non-convexity, a...

The paper investigates the influence of different model specifications for interpreting the results of discrete choice experiments when investigating heterogeneous public landscape preferences. Comparing model specifications based on the Mixed...

Animal-source foods are a major component of global diets and are increasingly criticised because of their adverse impacts on environment, climate and health. A shift in diets towards plant-based foods is a discussed option to overcome these...

Im vorliegenden Artikel wurde mithilfe eines Discrete-Choice-Experiments bestimmt, welche Faktoren die Entscheidung von Landwirten beeinflussen, an einem hypothetischen Förderprogramm zur Ansäuerung von Gülle bei der Feldausbringung teilzunehmen....

It has often been noted that the “null-hypothesis-significance-testing” (NHST) framework is an inconsistent hybrid of Neyman-Pearson’s “hypothesis testing” and Fisher’s “significance testing” that almost inevitably causes...

Swedish farmers were surveyed about their perceptions of genetically modified (GM) feed. Livestock in the EU are frequently given feed containing imported genetically modified (GM) crops, with GM fodder often being cheaper for farmers. However,...

Impacts on nature and landscape are to be offset in accordance with different nature conservation acts in various European countries. In Germany in particular, biodiversity offsets can also be made in advance, for instance, by booking them into...

Die Digitalisierung schreitet mehr und mehr voran und beeinflusst zunehmend Geschäftsabläufe in Unternehmen. Dem Handel über das Internet kommt in diesem Zusammenhang eine besondere Bedeutung für die zukünftige Entwicklung des ländlichen Raums...

This paper presents price and income elasticities of food demand for Germany. Using disaggregated household scanner data and the Quadratic Almost Ideal Demand System (QUAIDS). The QUAIDS is modified to account for censoring and include household...

Das Thema Elektromobilität in der Landwirtschaft gewinnt zunehmend an Relevanz, was sich beispielsweise in der Entwicklung erster elektrisch betriebener Traktorenkonzepte manifestiert. Ob sich diese Konzepte allerdings in der Breite etablieren...

Landwirte sowie Unternehmen der Agrar- und Ernährungswirtschaft werden beim Thema Nutztierhaltung mit vielseitiger werdenden gesellschaftlichen Anforderungen konfrontiert. Dabei spielen u.a. Umwelt- und Klimaschutzbedenken eine Rolle, insbesondere...

This paper provides an assessment of technical efficiency and productivity change for a sample of large-scale arable farms in Germany. For this, the paper applies input-oriented Data Envelopment Analysis (DEA) and Malmquist Index (MI) methods in...
