## Dedicated to E. Corominas Motivated by the problem of estimating the age (in generations) of a population that evolves according to the Galton-Watson process, we consider graded partially ordered sets on which a probability measure is defined. By looking at the antichain of maximal probability,

A strengthened form of the fixed point property for posets is presented, in which isotone functions are replaced by more general isotone relations. For finite posets, this 'relational fixed point property' turns out to be equivalent to dismantlability. But an example shows that not every infinite po
## Abstract This paper investigates the existence of threshold cointegration between real exchange rates and real interest rate differentials. Unlike previous work, which generally fails to find evidence of a longβrun relationship employing linear models, we employ tests of the null hypothesis of n
