a b s t r a c tA discrete choice experiment (DCE) is carried out to value socio-economic factors influencing the farmer's decision to report swine diseases and to assess the willingness of farmers to report swine diseases. Data were collected between March and July 2015 in two provinces in the Red River Delta, Northern Vietnam, from 196 pig producers by face-to face interview. A conditional logit model is used to measure the relative importance of the socio-economic factors and calculate the expected probability of disease reporting under changes of levels of these factors. Results of the study indicated that the likelihood of compensation and the type of culling implemented (all or only unrecovered pigs) are the two most important factors influencing farmer reporting. Compensation level, movement restriction and delay in compensation payment also have significant impacts on farmer's decision to report animal disease but they are not as important as the above factors. Three different scenarios including changes in six different factors (attributes) are tested to predict probability of animal disease reporting. Under the current situation (uncertainty of being compensated), only 4% of the farmers would report swine disease outbreak to the official surveillance system if the culling policy involves all pigs in affected farms. This number is increased to 26% if culling in affected farms is restricted to unrecovered pigs only. Ensuring certainty of compensation increases reporting probability by up to 50% and 90% if all or only unrecovered pigs are destroyed, respectively. The results of this study are important for improving the performance and sustainability of swine disease surveillance system in Vietnam.

“…The experimental design of the overall survey is based on the L MA design 1 generated internally from the support.CEs program [11], where the experimental design is directly from the orthogonal main effects plan [12]. This experimental design is generally larger than most orthogonal main effects plan for DCEs [13], which the authors mitigate through effective separation of the choice sets into multiple blocks; subsets of choice sets.…”

After the survey responses are encoded into a form legible by the program and supplementing it with previously generated survey design information, the commands are run to provide estimates for Malaysian home buyers' WTP for sustainable features using the conditional logit framework, shown in Table 4.…”

Abstract. The lack of data on sustainable home buying behaviour in developing countries such as Malaysia is due to the absence of sustainable housing itself. However, it is still possible to solicit home buyers for their stated preferences and quantify its effects on housing demand. In this study, a sample of 300 responses to a Discrete Choice Experiment (DCE) on sustainable housing features was analysed using the "support.CEs" program. This study found that the addition of sustainable features; renewable energy generation, enhanced soundproofing and ventilation, energy saving features, and higher green area ratios significantly increase home buyer's willingness to pay (WTP) for sustainable housing.

Tactical anger in negotiation: The expresser's perspective

Presenting programmed angry messages to a negotiator has increased concession rates in a series of recent experiments. But observing responses to a computer or confederate counterpart cannot yield insight into the perceptions, reactions, and negotiation outcomes experienced by those who actually deploy anger as a tactic.We report five studies examining the anger expression decision using a range of different methods. In the fully interactive two-person integrative negotiation in Study 1, expressed anger generally degraded trust while damaging implementation of deals.That ultimately diminished value actually claimed by anger expressers. In the discrete choice experiment of Study 2, sending angry messages proved costly for expressers, who registered very high levels of measured disutility from using this tactic. In Study 3, survey respondents reported widespread unwillingness to misrepresent anger during negotiation. Recalling a past negotiation, anger correlated negatively with experienced success, indicating that disutility from expressing anger generalizes widely across different contexts. Study 4 revealed that negotiators generally consider the tactic to be unethical. More than just specific beliefs about the lack of efficacy, Study 5 revealed that the source of tactical disutility lies in generalized discomfort with the misrepresentation of anger. Implications for research, practice, and training are considered.
