Using the case of chronic wasting disease (CWD) in white-tailed deer, we estimated hunters’ willingness-to-pay (WTP) for testing their game and determined how their perception of disease risk, trust, and confidence in wildlife agency affected hunter participation in ongoing disease surveillance. The average WTP for testing was $23.75 per deer, and it was positively related to trust and confidence in the wildlife agency and the perception of risk about deer populations in the declining area and the pathogen spreading to other areas. These findings imply that implementing active outreach programs can improve hunter participation in user-paid systems for CWD surveillance.

While historians believe that preserving a historic building in its original location is important to maintain its historic integrity, the general public's opinion is unknown. Survey data were gathered from local residents regarding a proposed relocation of a historic mill in rural West Virginia. Only a minority of the sample population supported preserving the mill at its original location. Willingness to pay for preservation was estimated at $8.45 for a one-time donation for the sample and $2.29 after adjusting for non-respondents using characteristics of the local population.

Soymilk is one of the fastest growing categories in the U.S dairy alternative functional beverage market. Using household-level purchase data from Nielsen's 2008 Homescan panel and the Tobit econometric procedure, we estimate conditional and unconditional own-price, cross-price, and income elasticities for soymilk, white milk, and flavored milk. Income, age, employment status, education level, race, ethnicity, region, and presence of children in a household are significant drivers of demand for soymilk. White milk and flavored milk are competitors for soymilk, and soymilk is a competitor for white milk. Strategies for pricing and targeted marketing of soymilk are also discussed.

The inclusion of cover crops in cropping systems brings direct and indirect costs and benefits. Farmers will adopt and utilize cover crops as long as the perceived benefit of using them is positive. This paper examines the demographic and management factors affecting the adoption and perceived benefit (in terms of improved crop yield) of using winter annual cover crops. A double selectivity model of cover crop adoption and perceived yield gain was estimated using survey data of Alabama farmers examining cover crop use and management. Results may help in understanding factors shaping farmers' perceptions, adoption, and retention of cover crops.

South Korea, the newest member to join the OECD's Development Assistance Committee, has signaled that it will become a major donor of official development assistance (ODA). Having had its own history of being a large recipient of ODA, South Korea claimed that it will provide aid from the recipient's perspective. Using panel data covering twenty-three years (1987–2009) and 154 recipient countries, we examine whether South Korea's ODA reflects the recipient nation's humanitarian needs more than the donor's interests. We ask three questions: (1) What are the major determinants of South Korea's ODA allocation? (2) Has South Korea's ODA policies changed over different time horizons—that is, years, political regimes? (3) Does South Korea exhibit different standards of allocating ODA for different groups of recipient countries? We find that South Korea provides more aid to higher-income developing countries with higher growth rates, which shows the tendency to serve the donor's economic interests. When we examine the data by time periods, we do not find significant differences over decades or political regimes. However, when we reexamine the data based on recipients' income levels, we find that the relationship between per capita income of the recipient country and ODA allocation is negative only for the middle-income or lower-middle-income group recipients and positive for the rest. This finding suggests the possibility that South Korea's ODA policy may have a dual-track structure.
