The effect of the Americans With Disabilities Act upon medical insurance and employee benefits

The Americans With Disabilities Act will have a significant impact upon plan sponsors and the administration of an employee benefit plan. Prior to the July 26, 1992 effective date, a plan sponsor or trustee should meet with the plan's attorney, provider and other insurance advisers and review the effect ADA will have upon the plan. The EEOC will be issuing additional interpretive rules before the effective date of ADA, and there will be numerous court challenges after the effective date. Plan sponsors and trustees should keep abreast of the developments as they occur. Before a benefit change or premium adjustment is made, it should be reviewed with legal counsel to assure that it conforms to ADA's insurance exemption. Plan sponsors and trustees should have legal counsel, the provider and the plan's insurance advisers develop the documentation that will enable the plan to establish ADA's insurance exemption to defend any legal challenge.     

Trade uncertainty and the two-step procedure: The choice of numeraire and exact indexation

Summary In a small open economy it is optimal to first maximize national income and second choose the best consumption point.The same two-step procedure under (quantitative) uncertainty is suboptimal if one of the goods is used as numéraire. Optimality is restored however, if nominal prices are deflated by the exact price index. Hence there is equivalence between the appropriate two-step procedure and the introduction of a stock market under uncertainty (Diamond 1967) under ideal circumstances.I would like to thank, without implicating, Peter van Bergeijk, Steven Brakman, Willem Buiter, Richard Gigengack, Jean-Marie, Viaene, Casper de Vries and an anonymous referee for useful comments and Angelique van Haasteren and Martijn Herrmann for graphical assistance.     

Policies for economic growth

Summary The old growth theory of the 1950s led to certain conclusions about the sorts of economic policies that would promote economic growth, and also about their limitations. The new growth theory of the 1980s makes much stronger assumptions and leads to correspondingly stronger conclusions about the scope of growth-promoting policy. This article argues that: (1) empirical work so far has neither confirmed nor denied the strong assumptions underlying the new theory; (2) the theory is worth pursuing because of its intrinsic interest and the possibilities it opens up; (3) whatever the final verdict on the new theory, both theory and evidence support the belief that significant long-run gains, even if not permanent changes in the growth rate, can be achieved by increased investment in the broadest sense, including human capital, technological knowledge, and industrial plant and equipment.Fifth Tinbergen Lecture delivered on October 4, 1991, in Amersfoort for the Royal Netherlands Economic Association
