    Description: Numerous studies analyze gender wage differences focusing on gross hourly wages. The analysis of differences in gross wages allows statements on productivity differences between men and women and to quantify the unexplainable wage gap which is often attributed to discrimination. While there is plenty evidence that the gender (gross) wage gap is a persistent labor market phenomenon, less is known about its effects on the income distribution. In this paper, we therefore go a step further and ask how differences in gross wages in particular the unexplained gap show up in disposable income and its distribution. This is particularly relevant from a policy perspective because of its implications for income inequality and working incentives. The empirical analysis is carried out for West Germany with data from the GSOEP pooled for the years 2006 to 2011. Germany is an interesting case because it is one of the few countries with a system of joint taxation for married couples. This leads to high marginal tax rates for second earners and affects after-tax income differences between men and women.

    Description: This paper aims at assessing the relationship between the possible existence of financial constraints and the decisions of Belgian private firms as regards their investments in both capital and R&D investments over the last decade. The main system GMM estimates from the error-correction equations indicate that the sensitivity of both types of investments to cash flow variations are rather differentiated. On the whole, these effects are more important for investments in ordinary assets, young small-scale firms located in the Walloon region that are not part of a multinational. Firms that perform R&D on a permanent basis and that receive public funds to support these activities appear to be less cash constraints.

    Description: We develop a new econometric framework that simultaneously allows recovering heterogeneity in demand, TFP and markups across firms while leaving the correlation among the three unrestricted. We do this by systematically exploiting assumptions that are implicit in previous firm-level productivity estimation approaches. We use Belgian firms production data to quantify TFP, demand and markups and show how they are correlated among them, across time and with measures obtained from other approaches. We also show to what extent our three dimensions of heterogeneity allow us to gain deeper and sharper insights on two key firm-level outcomes: export status and size.

    Description: In economics and other social sciences, complex processes are often represented by numerical models of reality which more or less well reflect behavioral relationships and interactions. Such attempts are the subject of a lecture course 'Mathematical Theory of Democracy' by the author at the Faculty of Economics of the Karlsruhe Institute of Technology. One new result in this field is presented here in the form of a statistical test to decide whether a political party or coalition of parties represents a majority of the population. For this purpose, party or coalition positions on a sample of policy issues, like introduction of a legal nationwide minimum wage, privatization of railways, and others, are compared with the results of public opinion polls on the same issues. The test is based on estimating the statistical significance of the coincidence observed (i.e. how likely is the coincidence by chance) to the end of accepting or rejecting the representativeness hypothesis. The test is developed for single parties and coalitions of two or three parties. It is illustrated with an estimation of representativeness of five major German parties and their potential coalitions basing on the official party manifestos published before the German parliamentary elections 2009 and on relevant polls of public opinion.
    Description: In der Ökonomie und den anderen Sozialwissenschaften wird immer wieder versucht, komplexe Prozesse der Wirklichkeit durch numerische Modelle abzubilden - was mit Abstraktionen für z. B. Verhaltens- und Wirkungsrelationen mehr oder weniger gut gelingt. Solche Versuche sind Gegenstand einer Vorlesungsreihe 'Mathematische Theorie der Demokratie' des Autors an der Wirtschaftswissenschaftlichen Fakultät des Karlsruhe Institut für Technologie. Ein neues Ergebnis in diesem Bereich wird hier vorgelegt in Form eines statistischen Tests, der entscheiden soll, ob eine politische Partei oder eine Parteienkoalition repräsentativ im Sinn der Bevölkerungsmehrheit agiert. Zu diesem Zweck wird die Übereinstimmung von Parteien- oder Koalitionspositionen mit Ergebnissen von Meinungsumfragen in der Bevölkerung verglichen, etwa zur Einführung eines bundesweiten gesetzlichen Mindestlohns oder der Privatisierung des Schienenverkehrs und anderem mehr. Der Test basiert auf der Einschätzung der statistischen Signifikanz der beobachteten Übereinstimmung (d.h. wie wahrscheinlich ist eine nur zufällige Übereinstimmung), um die Hypothese von der Repräsentativität der Politik zu akzeptieren oder abzulehnen. Die Studie spielt die Repräsentativität von einzelnen Parteien sowie von Zweier- und Dreier-Koalitionen durch. Darunter ist auch die Konstellation der fünf großen deutschen Parteien und ihrer potentiell möglichen Koalitionen auf der Basis der Bundestagswahl von 2009.
