It has been shown in the literature that if the individual consumers have constant but unequal time discount rates, then the representative consumer has discount rates that is a strictly decreasing function of time, just as is the case of hyperbolic discounting. No contribution, however, has so...

We investigate how an increase in transaction costs affect the equilibrium asset prices and allocations. We find a sufficient condition for an increase in transaction costs to increase buying prices, decrease selling prices, decrease the trading volume, and make all active traders worse off. The...

We generalize the classical expected-utility criterion by weakening transitivity to Suzumura consistency. In the absence of full transitivity, reflexivity and completeness no longer follow as a consequence of the system of axioms employed and a richer class of rankings of probability...

We provide a brief survey of some literature on intertemporal social choice theory in a multi-profile setting. As is well-known, Arrow’s impossibility result hinges on the assumption that the population is finite. For infinite populations, there exist non-dictatorial social welfare functions...
