Increasing returns to scale and the long-run Phillips curve

The Long-run Phillips Curve and Non-stationary Inflation

Modern theories of inflation incorporate a vertical long-run Phillips curve and are usually estimated using techniques that ignore the non-stationary behaviour of inflation. Consequently, the estimates obtained are imprecise and are unable to distinguish between competing models of inflation and test the veracity of a vertical long-run Phillips curve. We estimate a Phillips curve model taking i...

Increasing Returns and Long-Run Growth

This paper presents a fully specified model of long-run growth in which knowledge is assumed to be an input in production that has increasing marginal productivity. It is essentially a competitive equilibrium model with endogenous technological change. In contrast to models based on diminishing returns, growth rates can be increasing over time, the effects of small disturbances can be amplified...

Money illusion and the long-run Phillips curve in staggered wage-setting models

We consider the effect of money illusion defined referring to Stevens' ratio estimation function on the long-run Phillips curve in an otherwise standard New Keynesian model of sticky wages. We show that if households under-perceive real economic variables, negative money non-superneutralities will become more severe. On the contrary, if households over-perceive real variables, positive money no...

The Wage Curve and the Phillips Curve

Blanchflower and Oswald (1994) have argued that, in regional data, the level of unemployment is related to the fevel of wages. This result is at variance with an application of the original Phillips curve to regional data, which would predict that the change in wages ought to be related to the unemployment rate. On the other hand, there is considerable empirical support for the expectations-aug...
