We study the impact on payoff distribution of varying the probability (opportunity) that a player has of becoming the proposer in an ultimatum game (UG). Subjects' assignment to roles within the UG was randomised before the interactions. Subjects played 20 rounds anonymously and with random...

We introduce a framework of noncooperative pregames, in which players are characterized by their attributes, and demonstrate that for all games with sufficiently many players, there exist approximate (e) Nash equilibria in pure strategies. In fact, every mixed strategy equilibrium can be used to...

For each set of candidates at state and each profile of voters' preferences over running candidates a voting corresponsence selects a set of candidates. following Dutta, Jackson and Le Breton (Econometrica 2001) a voting correspondence is candidate stable if a candidate never benefits from...

The state-space method is applied to the problem of separating an autoregressive (AR) signal from composite AR and white normal noise. In the stationary case, for which the Wiener filter exists, we show explicitly its equavalence to the steady-state Kalman filter. Existing results for...

This paper evaluates theories aiming to explain the size and growth of government spending, develops a framework inclusive of the so-called guns vs. butter tradeoff effect, and offers insights especially for the period 1870-1938. There were differences between the excessive and responsive...

In large random economies with heterogeneous agents, a standard stochastic framework presumes a random macro state, combined with idiosyncratic micro shocks. This can be formally represented by a ran-dom process consisting of a continuum of random variables that are conditionally independent...

I suggest the idea of a reporting function, r(.), from reality to feelings. The ‘happiness’ literature claims we have demonstrated diminishing marginal utility of income. I show not, and that knowing r(.)’s curvature is crucial. A quasi-experiment on heights is studied.

This paper presents the partial analytical solution to a model of periodic consumption that incorporates imperfect capital markets and uncertainty. Our model assumes that consumption decisions occur more frequently than income receipt. We show that the week specific consumption functions can be...

This paper considers explicitly costly choice between mean-preserving distributions and a random variable. First, we extend a theorem of Diamond-Rothchild-Stiglitz to our environment. We then apply the result to risk and inequality analysis. W.r.t the former, we generalise Ehrlich and Becker's...

The three former High Commission Territories of Botswana, Lesotho and Swaziland (BLS) retain a special significance on the African scene by virtue of their peculiar relationship with South Africa. While their geographical positions force them into a high degree of economic and political...
