Digital risk management tools (RMTs) are promising to help farmers manage risk. However, these recently developed tools are still unexplored and hardly used by farmers. This study is the first to investigate how German farmers perceive the...

Improved varieties are considered critical for increasing crop yields worldwide. This study explored the effects of public agricultural extension and pest and disease experience on adoption of improved varieties using survey data on 525 wheat...

There is debate about whether maximum residue limits (MRLs) for pesticides act as a catalyst or barrier to trade. By constructing a trade model based on heterogeneous firm quality and productivity, we show that MRLs’ net effects on total export...

In recent years, land use data from the EU’s Integrated Administration and Control System (IACS) have become increasingly available for research purposes. IACS data contain annual plot-level information on cultivation and location of the land...

E-commerce in agriculture is gaining increasing attention, but market penetration is currently low, and companies are barely exploiting its full potential. Identifying and satisfying farmers’ expectations of e-commerce websites for farm inputs is...

Photovoltaics and wind energy must be considerably expanded to achieve the targeted climate neutrality in Germany in 2045 which may cause new conflicts. Especially ground-mounted photovoltaic systems, which are often associated with a high land...

We examine the relationship between nitrogen surplus per hectare and the median monthly wage per capita considering the Environmental Kuznets Curve (EKC) theory. The EKC hypothesizes an inverse U-shape relationship between environmental pollution...

The bioeconomy strategy of the European Union aims to balance three distinct goals: food security, the sustainable use of renewable resources for industrial purposes, and environmental protection. This study uses an integrated computable general...

Farmstead dairies are a small but growing segment in the German dairy market, but there is little information about them. They produce and process milk from their own farm or additionally from a small number of farms from the surrounding area and...

The new Common Agricultural Policy (CAP) reform has met with large-scale protests from farmers throughout Europe, intending to change one of the most controversial components: direct payments. We analyze German farmers' attitudes and understanding...

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...

Complementing more specific “p-value discussions”, this paper presents fundamental arguments for when null hypothesis statistical significance tests (NHST) are required and appropriate. The arguments, which are paradigmatic rather than...

In view of increasing energy and resource scarcities, nutrient recycling from domestic wastewater is a promising way to obtain mineral fertilizers. Given the lacking evidence about the acceptance of recycling fertilizers by the farming sector, we...

Many empirical studies have found Cumulative Prospect Theory (CPT) superior in depicting risk behavior compared to the expected utility approach and literature now offers also CPT related parameter estimates for European farmers. CPT combines two...

Official statistics are often based on samples representing a certain population. Because participation in a sample is usually voluntary, bias might result from so-called non-sampling errors such as nonresponse. Weighting procedures are intended to...

The war in Ukraine has led to massive price increases for agricultural inputs and products. This paper examines the effects on farm profitability and the consequences for the adoption of eco-schemes on arable farms. We use the large farm sample of...

In light of Russia’s war in Ukraine, three widely used trade and sector models were applied to assess: i) global food and nutrition security, ii) the effects on the bioeconomy, and iii) the implications for the European Common Agricultural...

Over the past decades, Ukraine has built an increasingly dynamic agricultural sector, characterized by growing export engagement in various commodities. Whether the country can quickly regain its status of a key player on the world agri-food markets...

Data Envelopment Analysis (DEA) is a popular tool to determine technical efficiency of agricultural production. One issue that arises in some nonparametric frameworks is the heterogenous endowment with determinate factors, such as agroclimatic...

Meat consumption has become increasingly relevant within the greater scientific, political, and public debate due to the variety of negative effects that it has on the environment, human health, and animal welfare. In Germany, the statistical basis...

This paper evaluates the occurrence and determinants of unfair trading practices (UTPs) in the fruit supply chain in Slovakia. Based on a representative survey of fruit growers, mainly apple growers, the study concludes that 79% of the producers...

The year 2021 shows a division between the development of the different global meat markets. Fueled by the Chinese market there was a strong demand for beef in particular coupled with a limited supply which results in strongly increased prices for...
