This paper illustrates the effects of item-nonresponse in surveys on the results of multivariate statistical analysis when estimation of productivity is the task. To multiply impute the missing data a data augmentation algorithm based on a normal/Wishart model is applied. Data of the German IAB...

Seit Beginn des vergangenen Jahres expandiert die Weltwirtschaft in moderatem Tempo. Allerdings gerät in den USA das Inflationsziel von 2% zusehends außer Reichweite, und die US-Zentralbank wird ihren Leitzins, anders als an den Finanzmärkten noch zu Jahresbeginn erwartet, im Sommer wohl...

Zu Beginn des Jahres 2024 zeigen Stimmungsindikatoren etwas aufgehellte Aussichten für die internationale Konjunktur. Dabei war die weltweite Produktionsdynamik noch bis Ende 2023 zurückgegangen. Ursachen waren hohe Inflation, restriktive Geldpolitik und in Europa der russische Krieg gegen die...

We study firm heterogeneity in a specific factors model to address the effect of factor mobility on reallocation gains from trade. A model is proposed with Melitz type firm heterogeneity with two sectors, two countries and two fixed factors and one factor mobile across sectors. Equilibrium in...

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...

The neoclassical model of the production function, as applied by Robert Solow to build the neoclassical model of growth, linked labor and capital to output. More recently, Romer and others have expanded the model to include measures of knowledge capital. In this paper we introduce a new factor,...

We explore the role of trade in differentiated final goods as well ollshoring of tasks for inequality both within and between countries. We emphasize the distinction between managerial and production labor. Managerial labor is a fixed input while production labor is a variable input. Following...

Our study shows empirically that the choice of resource allocation strategy affects innovation performance. A policy of allocating resources to a broader range of innovation projects increases sales of new products, especially if these are truly novel, i.e. new to the market. The effect of...
