It is wellknown that a group of individuals contributing to a joint production process with diminishing returns will tend, in equilibrium, to put in too little effort if shares of the output are exogenous, and will put in too much effort if their shares are proportional to their inputs. We...

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

The recent literature on “convergence� of cross-country per capita incomes has been dominated by two competing hypotheses: “global convergence� and “club-convergence�. This debate has recently relied on the study of limiting...
