Capital, Labour and Productivity: What Role Do They Play in the Potential Gpd Weakness of France, Germany and Italy?

The paper analyses the recent supply side developments in France, Germany, and Italy by employing a non-parametric approach to estimate potential GDP. The analysis reveals marked heterogeneity among the three countries with regard to the contribution made by labour input. Where similarities can be found, however, are in the slowdown of accumulation activity and in the pronounced worsening of total factor productivity. The paper is rounded out by estimates of some measures of wage pressures and of profitability in order to assess the role played by the movements of relative input prices in the intensity of use of primary factors in the production process.

The Cross-Section of Output and Inflation in a Dynamic Stochastic General Equilibrium Model with Sticky Prices

In a standard dynamic stochastic general equilibrium framework, with sticky prices, the cross sectional distribution of output and inflation across a population of firms is studied. The only form of heterogeneity is confined to the probability that the ith changes its prices in response to a shock. In this Calvo setup the moments of the cross sectional distribution of output and inflation depend crucially on the proportion of firms that are allowed to change their prices. We test this model empirically using German balance sheet data on a very large population of firms. We find a significant counter-cyclical correlation between the skewness of inflation and aggregates, but the relation with output is less sure. Our results can be interpreted as indirect evidence of the importance of price stickiness in macroeconomic adjustments.
