As the world's seventh largest wine producer (OIV, 2017), China plays a significant role in the world's wine industry. Classified as neither New or Old World it was recently classified into a "New, New World Category" (CNCCEF, 2009 Lawrence, 2016). This paper presents an overview of the Chinese...

The present study aims to measure the technical efficiency and establish core factors affecting rice production in Cambodia. A four-year dataset generated from the central government document 'Profile on Economics and Social' of 25 entire provinces between 2012 and 2015 and the stochastic...

This paper considers the portfolio problem for high dimensional data when the dimension and size are both large.We analyze the traditional Markowitz mean-variance (MV) portfolio by large dimension matrix theory, and find the spectral distribution of the sample covariance is the main factor to...

We analyzed the efficiency levels of nine of the largest commercial seed‐producing firms globally for the period 2008–2015 and assessed if there is a relationship between firm size and efficiency. We employed the nonparametric technique of data envelopment analysis (DEA) using an...

In the Indo-Gangetic Plains, one of India's most productive agricultural regions, smallholder livelihood vulnerability can inhibit sustainable development. As there are significant differences in economic development, natural resources and agricultural productivity within the region, we estimate...

The European Commission aims to achieve a climate‐neutral economy by 2050 and positively affect the employment growth rate while reducing fossil‐based production activities. For that reason, according to the European Green Deal, decarbonisation and modernisation of fossil‐based industries...

The availability of efficiency estimation software - freely distributed via the internet and relatively easy to use - recently inflated the number of corresponding applications. The resulting efficiency estimates are used without a critical assessment with respect to the literature on...

This paper aims to deliver empirical evidence on the links between production efficiency, biodiversity, and resource management by analysing a case study on small-scale tobacco production in the Miombo woodlands in Tanzania. The subsistence nature of tobacco production in Tanzania suggests that...

This paper focuses on smallholder maize production in Malawi by investigating the linkbetween productivity and soil fertility management. Many studies conducted in Malawi indicate declining levels of maize productivity thereby posing food security concerns, since maize is the staple crop for...
