Criticism of contingent valuation (CV) stresses warm glow and free-riding as possible causes for biased willingness to pay figures. We present an empirical framework to study the existence of warm glow and free-riding in hypothetical WTP answers based on a CV survey for the measurement of health-related Red Cross services. Both in conventional double-bounded and spike models we do not find indi...

Motorcyclists consist most of population of traffic foundation. More statistic of accident, more danger of injury, being in open and load environment can be of causes to make motorcyclists in exposure to more anxiety in comparison to other vehicles. Motorcyclist's anxiety can be one of the most significant reasons in accidents. In this study we surveyed the rate of anxiety in motorcyclists also...

This paper presents the study design and first experiences of a Pedelec Naturalistic Cycling study. There are 90 participants: 30 bicylists, 50 Pedelec cyclists and 10 E-bike cyclists. The bicycles are equipped with a data acquisition system that records among others speed data and videos on the traffic situation over a period of four weeks. Questionnaires assessing current travel and traffic b...

In epistemology and philosophy of science there has been a growing interest in group inquiry and ways that it might differ fundamentally from individual inquiry. The interest in this topic is understandable. Science is predominately collaborative work. If we want to understand the epistemic success of science, we need to understand group inquiry and it is an important part of this to learn whet...

We investigate a private value auction in which a single “entrant”on winning imposes a negative externality on two “regular”bidders. In an English auction when all bidders are active, “regular” bidders free ride, exiting before price reaches their values. In a …rst-price sealed-bid auction incentives for free riding and aggressive bidding coexist, limiting free riding compared to the English au...

The organizational form of franchising has been shown to yield higher profits and faster growth through reducing agency costs. Why then does anyone not franchise? In this paper I argue that the diffuse residual claims of the franchise system reduce overall system quality, and that this problem is inherent in the nature of franchising. The theory is tested by examining evidence from both the res...

In this study, we assessed indoor horse riding exercise's effects on basal physical exercise and activities of daily living (ADL) function using horse riding equipment, involving elderly test subjects (in their sixties). The participants were 20 people with no impediment to activity. They participated in experiments that lasted 60 min per day, 3 days per week, over 8 weeks, using the "SRider" (...
