Feasible directions in economic policy

Zoutendijk's method of feasible directions is used in this paper to derive numerical control strategies for the United Kingdom economy. The way in which the algorithm permits an examination of the sensitivity of the optimum short-term economic policy to changes in various assumptions demonstrates the versatility of the algorithm. Examined are the implications of different forms for the social welfare function; altering the length of the planning horizon, varying the magnitude of the terminal capital constraint, reducing the maximum permitted level of unemployment, changing the initial endowment of foreign currency reserves, fixing the interest rate for the whole planning period, and imposing a minimum growth rate for public expenditure.This work was supported in part by the National Science Foundation, Grant No. GK-10656X7.     

On desires and practical reasons

This paper challenges a common assumption about the relation between desires and practical reasons—namely, that if øing is an optimal way (or even just a way) for a person, P, to satisfy one of her desires, then P has a (normative) reason to ø. It challenges that assumption not by denying that desires are a source of practical reasons, but by showing that in some situations, rare though not impossible, P can lack a reason to ø despite having a desire that she could satisfy optimally by øing.     

Decentralized Robust Tracking and Model Following for Uncertain Large-Scale Interconnected Systems

The problem of the decentralized robust tracking and model following is considered for a class of large-scale interconnected systems with uncertainties. A class of continuous (nonlinear) decentralized state feedback controllers is proposed. The proposed robust decentralized controllers can guarantee that the tracking errors between each subsystem and the local reference model decrease to zero asymptotically. Finally, an illustrative example is given to demonstrate the validity of the results.
