This paper presents an econometric mediation analysis. It considers identification of production functions and the sources of output effects (treatment effects) from experimental interventions when some inputs are mismeasured and others are entirely omitted.

In the paper, the productivity growth of German sectors is analyzed. Sectoral production functions are estimated with annual national account data of 51 sectors from 1960-1990. Both, the pure Solow growth model and the Solow model augmented with human capital do not account for observed...

In the paper, the sources of productivity growth are investigated by an empirical analysis with micro data for West-German manufacturing firms. The theoretical framework corresponds to an augmented growth accounting approach based on a production function. The empirical results reveal that...

Empirical factor demand analysis typically involves making a choice from among several competing non-nested functional forms. Each of the commonly used factor demand systems, such as Translog, Generalized Leontief, Quadratic, and Generalized McFadden, can provide a valid and useful empirical...

Es wird eine Methode zur Messung des Produktionsfaktors Kapital vorgeschlagen, in der Vermögensarten nach ihrem Nutzungswert im Produktionsprozess gewichtet werden. Dazu werden Nutzungskosten für die einzelnen Anlageklassen mit Hilfe von Daten der Volkswirtschaftlichen Gesamtrechnungen sowie...

A method is proposed to measure capital services in production. This means that productive assets are weighted according to their user costs. The user costs of the individual asset classes are estimated based on data from the national accounts and other sources. The results show that, in the...

The CobbDouglas function is today one of the most widely adopted assumptions in economic modeling, yet both its theoretical and empirical bases have long been under question. This paper builds an alternative function on very different (albeit also neoclassical) microfoundations aimed at both...

Flexibility in response to competitive pressure from globalized markets and increasingly individualized customer desires has become vital for firms. A common strategy to address this challenge is to employ a dynamic concept of organization and reach beyond the boundaries of the firm....

Diese Arbeit untersucht anhand von PIRLS 2001 die unterschiedlichen Leseleistungen von Kindern an städtischen und ländlichen Grundschulen in Deutschland. Verwendet wird eine Dreiebenenanalyse, um nach und nach den vermeintlichen Stadt-Land-Unterschied durch Schüler-, Familien-, Klassen-,...
