The label "Keynes–Negishi equilibria" is attached here to equilibria in a monetary economy with imperfectly competitive product and labor markets where business firms and labor unions hold demand perceptions with kinks: as posited in Negishi's 1979 book Microeconomic Foundations of Keynesian Macroeconomics . Such equilibria are defined in a general equilibrium model, and shown to exist. Methodological implications are briefly discussed in a concluding section. 相似文献

Managing interest rate risk for property-liability insurers requires appropriate measurement of the sensitivity of liabilities to movements in interest rates. Most prior studies have assumed that interest rates shift in a parallel fashion and that the cash flows from liabilities are unaffected by interest rate changes. This article recognizes that unpaid property-liability (P-L) insurance losses are inflation-sensitive, that movements in interest rates will affect future claim payouts due to the correlation between interest rates and inflation and that interest rates are stochastic. The effective duration and convexity of P-L insurance liabilities calculated based on this approach are substantially lower than those measured using traditional approaches, which has important implications for asset-liability management by P-L insurers. 相似文献

The Carr-Darby shock-absorber hypothesis that unanticipated changes in the money supply cause changes in real balances but anticipated changes have a unit impact on the price level (and therefore leave real balances unchanged) is tested using two-step and joint estimation techniques. For the U.K., two-step methods appear to support the shock-absorber hypothesis, but the superior joint estimation technique decisively rejects the hypothesis, particularly the implicit rational expectations cross-equation restrictions. 相似文献

This analysis assesses Arizona's short-run price response to utility energy deregulation in the commercial and industrial sectors and the long-term response to deregulated industrial utility prices. Using a standard utility industry approach, ordinary least squares regression confirms commercial/industrial utility prices remain inelastic and Arizona's deregulation efforts have not effectively promoted short-run price competition. Moreover, widening differences in utility rates could be a response to a stronger long-run price elastic effect across states. The findings suggest states not aggressively deregulating utility price to narrow artificial comparative price advantages could be at a competitive disadvantage for interstate manufacturing investment.
