BACKGROUND Multiple sclerosis (MS) is an important problem both for people with the disease and for society. There is no cure, and alleviation of symptoms forms the cornerstone of care. Excessive fatigue that severely limits activity is experienced by at least two-thirds of the estimated 60,000 people with MS in the UK. OBJECTIVES (1) To identify current(More)
This paper explores the effect of the possibility of third-party intervention on behavior in a variant of the Berg, Dickhaut, and McCabe (1995) “Investment Game”. A third party’s material payoff is not affected by the decisions made by the other participants, but this person may choose to punish a responder who has been overly selfish. The concern over this(More)
BACKGROUND Fatigue is one of the most common and disabling symptoms of people with Multiple Sclerosis (MS). The effective management of fatigue has an important impact on the patient's functioning, abilities, and quality of life. Although a number of strategies have been devised for reducing fatigue, treatment recommendations are based on a limited amount(More)
Using an international dataset of about 35,000 subjects, this paper provides an empirical example of high-stakes incentives in relation to religious practice. First, we show that incentives (based on absolute belief) play a salient role in religious performance. Second, we find that, when both positive (heaven) and negative (hell) incentives are available,(More)
We present a lab-field experiment designed to assess systematically the external validity of social preferences elicited in a variety of experimental games. We do this by comparing behavior in the different games with a number of behaviors elicited in the field and with self-reported behaviors exhibited in the past, using the same sample of participants.(More)
This paper studies the empirical relationships that exist between public investment and per capita income growth over the period 1965-1995 in the different Spanish regions. Using a neoclassical growth model with public and human capital, we derive a convergence equation, estimated through panel data techniques. Besides providing evidence in favour of the(More)
In this paper we use payment cards in experimental games, specifically in a Prisoners’ Dilemma game. This provides us with information about beliefs. We are able to characterise individual behaviour according to both actions and beliefs. We ...nd that (i) half of the population thinks that social issues do not matter, (ii) 17% of the population believes(More)
Recent mechanic models of network formation have theoretically and empirically established the role of local and global search in the formation of social networks. However, the economic forces behind the dynamics of these models has been underexplored. In this paper, we propose a dynamic network formation model that builds on standard microeconomic concepts(More)
