This paper estimates Okun's law in the EU15 countries between 1980 and 2018. It employs three different versions of the law with a focus on the dynamic part of the relationship. We find that the negative relationship between unemployment and output holds for most countries and is fairly stable...

The unemployment rate in Australia is modelled as an assymmetric and non-linear function of aggregate demand, productivity, real wages and unemployment benefits. Negative changes in aggregate demand cause the unemployment rate to rise rapidly, while real wage rigidity contributes its to slow...

The unemployment rate in Australia is modelled as an asymmetric and nonlinear function of aggregate demand, productivity, real interest rates, the replacement ratio and the real exchange rate. If changes in unemployment are big, the management of of demand, real interest rates and the...

Models of the aggregate unemployment rate have traditionally been estimated from structural models of the labour market or in a linear single-equation framework. However, theory as well as evidence suggest that the unemployment rate is asymmetric and should be modelled in a non-linear framework....
