Optimal control of a linear process with unknown parameters is considered when the horizon is infinite and rewards are discounted. Active learning strategies are considered, i.e., agents consider the information value of possible actions, as well as current reward. Distributional assumptions are...

A standard model of intertemporal allocation (described by a technology set and a welfare function defined on consumption) can be reduced to one described by a technology set and a utility function defined on this set. The authors present an example to show that even when the welfare function is...

This paper shows that, in the domain of piecewise linear statutory income tax functions, the principle of equal sacrifice implies tax progressivity. The progressivity implication of the doctrine is, in fact, stronger: the equal sacrifice principle, in essence, characterizes marginal rate...

We study the underlying structure of the two-dimensional dynamical system generated by a class of dynamic optimization models that allow for intertemporal complementarity between adjacent periods, but preserve the time-additively separable framework of Ramsey models. Specifically, we identify...
