چکیده
at+1 = (1 + r)(at + yt − ct), t = 0, 1, . . . , T r > 0, a0 given Where at denotes assets (or wealth) held at the beginning of period t, yt is labor income in period t, ct denotes consumption expenditure incurred in period t, β is the discount factor, r is the interest rate, and u() represents the period-by-period utility function, assumed to be twice continuously differentiable, strictly increasing and strictly concave. We also assume that limct→0 u (ct) =∞.

Time Preference and its Effects on Intertemporal
Time preference has a peculiar role in determining the level of economic activities. Time preferenceis the most important origin of interest rate. In this paper we study the founders and defenders'viewpoints about time preference and then we try to criticize them. It seems that discounting futureutilities is resulting from irrationality and it is ethically indefensible too. From mathematical as...

متن کاملTime-Consistency: from Optimization to Risk Measures
Stochastic optimal control is concerned with sequential decision-making under uncertainty. The theory of dynamic risk measures gives values to stochastic processes (costs) as time goes on and information accumulates. Both theories coin, under the same vocable of time-consistency (or dynamic-consistency), two different notions: the latter is consistency between successive evaluations of a stocha...

متن کاملAn Analysis the Effect of Capital Taxation on Allocation of Resources: A Dynamic Equilibrium Model Approach
Abstract T he return of capital is fundamental to the intertemporal allocation of resources by changing the consumption behavior and capital accumulation over time. Taxation on return of capital increases the marginal product of capital, meaning that capital stock is lower than when capital is not taxed, which results decreased growth and welfare in steady state. This pape...
