Using panel data of 83 counties observed from 2000 to 2015, the marginal abatement cost (MAC) of soil erosion is accurately evaluated by directional distance function with convex expectile regression. Besides, we further explore how the external variables affect shadow prices and the choice of...

Mitigating the environmental impact of agriculture is a major issue in negotiations on the future of the European Union's Common Agricultural Policy. Organic farming is commonly put forward in these discussions as a promising way to reduce the negative environmental impact of agriculture....

Agri-environmental-climate schemes provide payments for ecosystem services by compensating farmers to implement management actions or obtain ecological results. To compare farmer preferences for action-based schemes, result-based schemes, or a hybrid, we conduct a discrete choice experiment in a...

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...
