“…Scholars such as, Parsons and Kealy (1992), Parsons and Needelman (1992), Feather (1994), andBayer et al (2007) showed that using alternatives in estimation can obviate such difficulties and produce consistent parameter estimates as also suggested by McFadden (1978). Von Haefen and Domanski (2018) confirmed that larger efficiency losses arise with smaller samples as predicted by theory. Therefore, the mixed logit model is considered to be the most promising state-of-the-art discrete choice model currently available.…”

Visitor preferences on different safari tour packages: A Case Study of Udawalawe National Park in Sri Lanka

In Sri Lanka, visitors to national parks are not offered a choice when they go on safari tours regarding the type of wildlife viewing that they are interested in such as elephant watching, bird watching or general wildlife viewing. Although wildlife watching is as much a recreational activity as an educational activity, visitor requirements are often not met at national parks. In the present study, under different prices, facilities and services, four tour packages were presented to the visitors as choice sets at Udawalawe National Park (UNP) in Sri Lanka. Four hundred visitor groups were surveyed at the ticket-issuing office located at the entrance to the UNP within a 06 months' period covering week days, weekends, holidays and school vacations. A choice experiment was conducted and 'different willingness to pay (WTP) values were estimated for the safari tours. In addition, the WTP values for the visitor facilities and services presented to visitors were estimated. There was a significant difference in demand for the attributes found in tour packages. The majority were willing to pay more for the attributes of distance to be travelled and the availability of a professional guide in the safari vehicle. There was less demand for the facility of 'open hood' and one stop relaxation service in the tour package. The findings of the study will be helpful to park managers in proposing a price structure for safari tours and in providing a proper service to visitors at the UNP.

“…To evaluate the welfare effects of a reform on physicians, we calculated, for each doctor, his EV, that is, the minimum payment he would be willing to accept to forego the reform. Our calculations are based on simulation procedures, first suggested in McFadden (1999), and applied in several papers on discrete choice (see, e.g., Creedy et al, 2011; Herriges & Kling, 1999; von Haefen & Domanski, 2018). Of course, these welfare measures are partial as they do not provide information on the impact of a reform neither on patients' welfare (i.e., quality of services) nor on tax payers' welfare.…”

Based on linked administrative and survey panel data, we analyse the labour supply behaviour of physicians who could adopt either a standard fee-for-service contract or a mixed remuneration (MR) contract. Under MR, physicians received a per diem and a reduced fee for services provided. We present estimates of a structural discrete choice model that incorporates service intensity (services provided per hour) and contract choice into a labour supply framework. We use our estimates to predict (ex ante) the effects of contracts on physician behaviour and welfare, as measured by average equivalent variations. The supply of services is reduced under an MR contract, suggesting incentives matter. Hours spent seeing patients is less sensitive to incentives than the supply of services. Our results suggest that a reform forcing all physicians to adopt the MR system would have substantially larger effects on physician behaviour than were measured under the observed reform. A pure salary (per diem) reform would sharply reduce services but would increase time spent seeing patients.

“…Here, and while there is no proof that this strategy will generate consistent parameter estimates in non-CL models, it has been found in various studies to only result in small or modest efficiency losses when sampling reasonable numbers of alternatives (e.g. Daly et al 2014;von Haefen and Domanski, 2018).…”

Highlights Serious acquisitive crime offenders vary in their offence location preferences  Conditional logit estimates of these preferences can be biased due to heterogeneity  Model fits suggest heterogeneity can be modelled using mixed logit or latent class  Mixed logit and latent class can however give slightly different results  Latent class though shows the heterogeneity can be linked to types of offenders
