We consider the estimation of the mean of a multivariate normal distribution with known variance. Most studies consider the risk of competing estimators, that is the trace of the mean squared error matrix. In contrast we consider the whole mean squared error matrix, in particular its...

We characterize the unique Markov perfect equilibrium of a tug-of-war without exogenous noise, in which players have the opportunity to engage in a sequence of battles in an attempt to win the war. Each battle is an all-pay auction in which the player expending the greater resources wins. In...

Well-being (i.e., satisfaction, happiness) is a latent variable, impossible to observe directly. Hence, questionnaires ask people to grade their well-being in different life domains. The most common practice-comparing well-being by means of descriptive analysis or linear regressions-ignores that...

This paper reviews developments in income and health poverty in Ireland over the 2003-2011 period using data from the Survey of Income and Living Conditions (SILC). It also examines developments in the correlation between the two. Income poverty fell up to and including 2009, after which this...

elimination of weakly dominated strategies may be order-dependent, one may suspect that the same holds for conditional dominance …. We prove that, although the sets of strategy profiles surviving two arbitrary elimination orders of conditional dominance …_i(s_i))_i$ induces the same {\em terminal node} as $s$ does. To prove our results we put forward a new notion of dominance and an …
