Joe DeRita is giving an economic briefing before the Senate Banking Committee. During his testimony, Senator Morris Howard states, "Based on the Phillips curve relationship, if we increase the inflation rate from 3% to 5% , we can achieve a reduction in the rate of unemployment in both the short run and the long run. " Senator Lawrence Fine adds, "Furthermore, if the central bank is able to credibly announce that they will maintain the money supply growth rate, so that the increased inflation rate is well anticipated, borrowers, lenders, workers, and employers will incorporate the new higher rate of inflation into long-term contracts, so there will be no adverse impact on the economy.
