Intergenerational Mobility and Marital Sorting

We use data from the German Socio-Economic Panel and the British Household Panel Survey to estimate the extent of intergenerational economic mobility in a framework that highlights the role played by assortative mating. We find that assortative mating plays an important role. On average about 40-50% of the covariance between parents' and own permanent family income can be attributed to the person to ...

Home-Market and Factor-Endowment Effects in a Gravity Approach

This paper shows how the home-market effect can be estimated in the generalized gravity equation of Bergstrand, taking into account traditional comparative advantage effects arising from differences in factor endowment. The empirical results suggest the presence of significant home-market effects for differentiated goods in many manufacturing industries which may be capital intensive or labour intensive. ...

Cohort Effects and the Returns to Education in West Germany

Using a Mincer-type wage function, we estimate cohort effects in the returns to education for West German workers born between 1925 and 1974. The main problem to be tackled in the specification is to separately identify cohort, experience, and possibly also age and year effects in the returns. For women, we find a large and robust decline in schooling premia: In the private sector, the returns to a ...

Estimation of Multinomial Logit Models with Unobserved Heterogeneity Using Maximum Simulated Likelihood

In this paper, we suggest a Stata routine for multinomial logit models. - with unobserved heterogeneity using maximum simulated likelihood based on. - Halton sequences. The purpose of this paper is twofold. First, we describe the. - technical implementation of the estimation routine and discuss its properties. Further,. - we compare our estimation routine with the Stata program gllamm, which. - solves ...

Much Ado about Nothing: Conditional Logit vs. Random Coefficient Models for Estimating Labour Supply Elasticities

This study compares several specifications of discrete choice labour supply estimations on basis of the German Socio Economic Panel. The results suggest that despite the restrictive assumptions of the error terms the conditional logit model provides an adequate model choice for the analysis of labour supply functions. Significance tests, which are based on bootstrapped confidence intervals, show that ...

Verhaltensänderung durch Einführung der Praxisgebühr und Ursachenforschung: erste empirische Ergebnisse

Im Zuge des GKV-Modernisierungsgesetzes wird seit dem 1. 1. 2004 eine sog. Praxisgebühr von 10 Euro pro Quartal für ambulante Arzt- und Zahnarztbesuche erhoben. Neben einem Beitrag zur Konsolidierung der Finanzlage der GKV sollte die Praxisgebühr auch eine Verhaltensänderung der Versicherten bewirken. Der Beitrag zeigt auf, dass die Zahl der Arztbesuche im Jahre 2004 im Vergleich zum Jahr 2003 signifikant ...

Contribution to Productivity or Pork Barrel? The Two Faces of Infrastructure Investment

This paper proposes a simultaneous-equation approach to the estimation of the contribution of transport infrastructure accumulation to regional growth. We model explicitly the political-economy process driving infrastructure investments; in doing so, we eliminate a potential source of bias in production-function estimates and generate testable hypotheses on the forces that shape infrastructure policy. ...

Social Anomie and Racial Segregation in South Africa

The concept of anomie is one of the classics of sociological theory. Developed by scholars such as Emile Durkheim and Robert K. Merton, the concept refers to the absence of clear social norms and values and to a lack of sense of social regulation. However, whereas Merton focused on features of relative deprivation that cause anomie, Durkheim was primarily interested in the link between rapid social ...

Introducing Environmental Externalities into Transport Pricing: Measurement and Implications

It is European Commission policy to charge modes of transport according to the marginal social cost of their use of the infrastructure, including environmental costs. However, progress in implementing this process has been slow, partly because of the difficulty of measuring and valuing these costs. This need has led to a great deal of research in this area in recent years. The paper presents the results ...

A Game Theoretic Model of the Northwestern European Electricity Market: Market Power and the Environment

This paper develops a static computational game theoretic model. Illustrative results for the liberalising European electricity market are given to demonstrate the type of economic and environmental results that can be generated with the model. The model is empirically calibrated to eight Northwestern European countries, namely Belgium, Denmark, Finland, France, Germany, The Netherlands, Norway, and ...

A Simple, Analytically Solvable, Chamberlinian Agglomeration Model

This paper presents a simple Chamberlinian agglomeration model which, like the canonical core-periphery (CP) model, contains two agglomerative forces. However, in contrast to that model, the present model is analytically solvable. Moreover, the present model exhibits a "supercritical pitchfork bifurcation" rather than the "subcritical pitchfork bifurcation" of the CP model. This may be a better description ...

Economic Integration, Wage Policies, and Social Policies

This paper sets up a two country monopolistic competition model with intra-industry trade to study the effects of an exogenous differential in wage and social policies on the location of industry. Two model scenarios are considered. In the traditional one with physical capital, such a differential induces a relocation effect which increases with the level of trade integration. The 'new economic geography' ...
