The present paper explores the connection between inflation and unemployment in different models with fair wages both in the short and in the long runs. Under customary assumptions regarding the sign of the parameters of the effort function, more inflation lowers the unemployment rate, though to a declining extent. This is because firms respond to...

... the same reasoning above regarding the elasticity of the wage to the unemployment rate we set ( = 0:5: We log-linearize the system around the steady state. The short-run Phillips curve with …xed and varying capital are plotted in Figure 7. The result that higher in ‡ation goes hand in hand with a lower unemployment rate, whose intuition was discussed commenting equation (17), is con…rmed also for the present model. ...

... it is possible to see, varying capital implies a ‡atter short run Phillips curve than under …xed capital, given that the boom following a monetary expansion is reinforced by an increase of investments, which rise upon impact by 0.08% 10 . Figure 7 also shows that increasing trend in ‡ation decreases the responsiveness of both the in ‡ation and unemployment rates to a 1% monetary shock. This is consistent with our results above that increasing trend in ‡ation ‡attens the stable arm of the economic system without capital and it can be explained by keeping in mind two facts. ...

The paper builds on the Goodwin (1967) model which describes the distributive cycle of capitalist economies whereby mass unemployment is generated periodically through the conflict about income distribution between capital and labor. We add to this model a segmented labor market structure with fluid, latent, and stagnant components. The model exhib...

Increasing evidence shows that in the aftermath of the global financial crisis, in the euro area, the relationship between price inflation and economic slack became stronger. Instead, there is no clear evidence of a strong(er) relationship between wage inflation and unemployment. In this paper, we estimate a Phillips curve with time-varying coeffic...

This article attempts to investigate the potential relationship and significance of various determinants of Total Factor Productivity (TFP) in India for the 1980–2016 time period. Specifically, this is achieved in two stages. In the first, the standard growth accounting approach is used to measure the changes in TFP. Then, the main model for establ...

The primal and dual measures of capacity utilization under certain conditions, such as the nature of the economy of scale, have been widely used to analyze the current state of the economy in explaining the labor productivity and the inflation rate. However, the characteristics of certain measures are the ad hoc, since they are not based on explici...
