A set of new power indices is introduced extending Banzhaf power index and allowing to take into account agents’ preferences to coalesce. An axiomatic characterization of intensity functions representing a desire of agents to coalesce is given. A set of axioms for new power indices is...

Previous sensitivity analysis procedures for applied general equilibrium models have focused on the values of exogenously assigned elasticity parameters, while the calibrated parameters - those that are obtained from combining elasticity information with flow or stock data - have been largely...

Unemployment durations are generally modelled by specifying the conditional probability of leaving unemployment (the hazard function). Existing studies for Britain all use very restrictive parametric specifications of the hazard function, mostly commonly Weibull in form. These restrictions...

We analyze a two-stage patent race. In the first phase firms seek to develop a research tool, an innovation that has no commercial value but is necessary to enter the second phase of the race. The firm that completes the second phase of the race first obtains a patent on the final innnovation...

I study the impact of idiosyncratic risk on savings and employment in a small open economy populated by two-member families. Families incur a fixed cost of participation when both members are employed. Because of market incompleteness and information asymmetries, this cost coupled with labor...

In this paper we investigate the multi-period forecast performance of a number of empirical self exciting threshold autoregressive (SETAR) models that have been proposed in the literature for modeling exchange rates and GNP, amongst other variables. An indicator of when such models are likely to...

This note reexamines the single-profile approach to social-choice theory. If an alternative is interpreted as a social state of affairs or a history of the world, it can be argued that a multi-profile approach is inappropriate because the information profile is determined by the set of...

The aim of this paper is to evaluate the impact of monetary policy in tests of the Expectations Hypothesis of the term structure of interest rates. We apply the model developed by McCallum (1994b), in which the Expectations Hypothesis interacts with a policy reaction function and with a...
