Compared to earlier studies we use a data set with more variation in unemployment, and which allows for controlling for a host of factors that influence the effect of government purchases. We find that increased government purchases lead to lower unemployment; an increase equal to one percent of GDP reduces unemployment by 0.2 percentage point in the same year. The effect is greater in downturns than in booms, and also greater under a fixed exchange rate regime than under a floating regime. Terms of use: Documents in EconStor mayJEL-Code: E620, H300.

We focus on the equilibrium unemployment rate as a parameter implied by a dynamic aggregate model of wage and price setting. The equilibrium unemployment rate depends on institutional labour market institutions through mark-up coefficients. Compared with existing studies, the resulting final equation for unemployment has a richer dynamic structure. The empirical investigation is conducted in a panel data framework and uses OECD data up to 2012. We propose to extend the standard estimation method with time dummies to control and capture the effects of common and national shocks by using impulse indicator saturation (WG-IIS), which has not been previously used on panel data. WG-IIS robustifies the estimators of the regression coefficients in the dynamic model, and it affects the estimated equilibrium unemployment rates. We find that wage co-ordination stands out as the most important institutional variable in our dataset, but there is also evidence pointing to the tax wedge and the degree of compensation in the unemployment insurance system as drivers of equilibrium unemployment.

Wage coordination plays an important role in macroeconomic stabilization. Pattern wage bargaining systems have been common in Europe, but in different forms, and with different degrees of success in terms of actual coordination reached. We focus on wage formation in Norway, a small open economy, where it is custom to regard the manufacturing industry as the wage leader. We estimate a model of wage formation in manufacturing and in two other sectors. Deciding cointegration rank is an important step in the analysis, economically as well statistically. In combination with simultaneous equation modelling, the cointegration analysis provides evidence that collective wage negotiations in manufacturing have defined wage norms for the rest of the economy over the period 1980(1)–2014(4).

Declining unionization rates and job polarization are two important labor market developments of recent decades. A large body of literature has analysed these phenomena separately, but little has been done to see whether there is a link between them. We employ a macroeconomic model for a small open economy with a large input-output core to analyse how deunionization may cause job polarization. Our analysis shows that medium-skilled workers are negatively affected by deunionization, mainly as a result of the heterogeneity of the elasticities of substitution between different types of labor. While the elasticities of substitution between highand medium-skilled labor are relatively low, the elasticities of substitution between medium-and low-skilled are relatively high. As a result, when deunionization leads to increased wage dispersion, we find that demand for low-skilled increases at the expense of medium-skilled labor, thus yielding a more polarised labor market. We would like to thank Pål Boug, Ådne Cappelen, Håvard Hungnes and Ingrid Bjartveit Krüger for inspiration and discussions, to Roger Hammersland for technical support in designing an automatic procedure for estimating the system of cost share equations and to Jørgen Ouren for carrying out the calculations.

We investigate empirically the effect of government purchases on unemployment in 20 OECD countries, for the period 1960-2007. Compared to earlier studies we use a data set with more variation in unemployment, and which allows for controlling for a host of factors that influence the effect of government purchases. We find that increased government purchases lead to lower unemployment; an increase equal to one percent of GDP reduces unemployment by 0.2 percentage point in the same year. The effect is greater in downturns than in booms, and also greater under a fixed exchange rate regime than under a floating regime. JEL-Code: E620, H300.
