Spencer‐Cotton, Alaya, Marit E. Kragt, and Michael Burton. "Spatial and Scope Effects: Valuations of Coastal Management Practices." Journal of Agricultural Economics 69.3 (2018): 833-851.

Abstract: We explore how values for environmental management in the Kimberley region of Australia respond to changes in spatial scale and attribute scope. A discrete choice experiment was conducted that included the impacts of management on marine no‐take areas, Aboriginal rangers, recreational facilities, and coastal development. A split sample single‐site design was used to estimate values for the Kimberley region as a whole, and for two separate smaller sub‐regions, allowing us to test for spatial preference heterogeneity. Management outcomes for different regions were displayed on a map to show respondents explicitly where outcomes would occur. We show that willingness to pay results are similar between the two smaller sub‐regions, and that willingness to pay for the attributes increased when management occurred at the larger geographical scale. However, respondents were somewhat insensitive to changes in the scope of the two cardinal attributes: area of no‐take and number of rangers. We discuss the implications of this spatial and scope insensitivity for choice experiment research.

Lan, Hao, and Paul W. Dobson. "Healthy competition to support healthy eating? An investigation of fruit and vegetable pricing in UK supermarkets." Journal of Agricultural Economics  68.3 (2017): 881-900.

Abstract: Governments and public health officials are urging the public to eat more fruits and vegetables to contribute to a healthy diet. However, there is concern that a lack of effective competition amongst supermarket retailers has resulted in inflated prices for these products which are deterring consumers from eating more of these healthy foods. We investigate this by examining the nature and extent of price competition for fresh fruits and vegetables amongst UK supermarket retailers, drawing on a panel of weekly retail and corresponding wholesale market prices over a seven‐year period. We find that the extent of supermarket competition varies across the products, being quite intense on some but much weaker on others, where the retailers do not fully respond to each other's prices and where the extent of their competitive interaction varies significantly with each other.
