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. ER -
