We consider a finite-horizon, multiechelon inventory system in which the surplus of stock can be sold (i.e., disposed) in the secondary markets at each stage in the system. What are called <i>nested echelon order-up-to policies</i> are shown to be optimal for jointly managing inventory replenishments...

Dynamic programming techniques are often used in economy due to the recursive structure that many dynamic economic optimization problems have. These problems, usually having a complex form, are disintegrated into smaller sub-problems whose optimal solutions lead to the optimal solution of the...

This paper studies optimal monetary and fiscal policies in an economy à la Lucas and Stokey (1983) and Lagos and Wright (2005) with multiple cash and credit goods. We show that optimal policies are in general time inconsistent due to insufficient number of instruments to influence future...

The EU 2020 process has the key headline target of raising the average employment rate in the EU to 75 from the present 69 per cent. In this paper, we first derive a new result for optimal policymaking under uncertainty. It consists of two components : one of a unilateral policy reaction under...

In this paper we study the optimal policy in the Uzawa–Lucas model with externality in human capital when agents value both consumption and leisure. We find that the government pursuing the first best can achieve its goal by a subsidy which depends on foregone earnings while studying and which...

This paper analyzes the optimal fiscal policy in an endogenous growth model with productive public services. Government expenditure, which may be subject to different degrees of congestion, is financed by distortionary income taxation. The standard result on the equality between the...

In this paper weighted singularly perturbed hybrid stochastic systems are discussed. Under some reasonable assumptions, it is shown that there exists a uniformly δ-optimal policy when the perturbation is sufficiently small. Copyright Springer-Verlag Berlin Heidelberg 2005
