A generalization of the QALY model for general health profiles is provided in this paper. Twonatural assumptions on inter-temporal preferences play a key role in arriving at our representation.The first one, Indifference to the future afterdeath, is uncontestable in our framework, and thesecond...

We present a model in which the consumers' capacity to access a service provided on a network depends negatively on the price charged by the network owner per capacity unit. Several scenarios concerning the structure of the downstream service provision market are studied. First, a monopolist...

In this paper we study a situation were the planner cannot commit to a mechanism and the outcome function is substituted by the planner herself. We assume 1) agents have complete information and play simultaneously; and 2) given the messages announced by the agents, the planner reacts in an...

In the context of time series regression, we extend the standard Tobitmodel to allow for the possibility of conditional heteroskedastic error processes of the GARCH type.We discuss the likelihood function of the Tobit model in the presence of conditionally heteroskedastic errors.Expressing the...

The present paper develops a simple model of a network structure to analyze the profitability and the strategic effects of airline alliances in which two complementary alliances, following different paths, may be formed to serve a certain city-pair market. We examine whether airlines that employ...

We compare sequential and bundle auctions in a framework of successive procurement situations, where current success positively affects future market opportunities and competition varies across projects. We find that - if allocation of the projects has to be ensured - bundle auctions with...

We study culture and risk aversion as causes of gender differences in ultimatum bargaining. It has often been conjectured in the literature that gender differences in bargaining experiments are partly due to differences in risky decision making. Using the data obtained from our experimental...

Repeated games with probabilistic horizon are defined as those games where players have a common probability structure over the length of the game's repetition, T. In particular, for each t, they assign a probability pt to the event that "the game ends in period t". In this framework we analyze...

The living standard indicator in utilitarian social evaluation functions (USEF) is the ratio of a nominal living standard and a price index. We show that under weak association of price indices and nominal living standards and usual concavity conditions on utility functions, utilitarian social...

In a choice situation, it is usually assumed that the agents select the maximal elements inaccordance with their preference relation. Nevertheless, there are situations in which a selectioninside this maximal set is needed. In such a situation we can select randomly some of thesemaximal...
