Fair", institution = "National Bureau of Economic Research", type = "Working Paper", series = "Working Paper Series", number = "1377", year = "1984", month = "June", URL = "http://www.nber.org/papers/w1377", abstract = {Three models of price and wage behavior are estimated and tested in this paper. Model 1 is one in which the long-run trade-off between unemployment and inflation is in terms of price levels; Model 2 is one in which the trade-off is in terms of rates of change; and Model 3 is one in which there is no long-run trade-off. The evidence favors Model 1 over Models 2 and 3. The comparison between Models 2 and 3 is inconclusive. The short-run trade-offs are greater for Model 1 than for Models 2 and 3. The fact that Model 3 did not do particularly well is evidence against the Friedman-Phelps proposition of no long-run trade-off.}, }
