Mr. Roberts, who as a member of Jack Kemp's staff had played had a large part in drafting the Kemp-Roth bill, and Mr. Malkiel, the author of A Random Walk down Wall Street, discuss what might be done to halt the Carter inflation. Their ideas hold up well in post-Reagan Revolution hindsight. BM: "I think as the recession deepens, which I expect it will, there will then be ample opportunity for tax cuts, which I think will have to be done not in the old way of stimulating consumption, but in a newer way of stimulating research and development, investment, and the things we've been talking about--and that may be the way that we start putting some of these things together and move in the direction of these supply incentives."
