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' ...

Berufliche Segregation im Kontext: über einige Folgen geschlechtstypischer Berufsentscheidungen in Ost- und Westdeutschland

Sichern "Männerberufe" tatsächlich einen besseren Erwerbseinstieg als "Frauenberufe"? In welchem Ausmaß können frauen-bzw. männerdominierte Berufe im Leben junger Menschen erwerbsbiographische Kontinuität stiften? Ausgehend von der Überlegung, dass die Konsequenzen geschlechtstypischer Berufsentscheidungen mit den konkreten wirtschaftsstrukturellen und institutionellen Rahmenbedingungen variieren, ...

Using Analysis of Gini (ANOGI) for Detecting whether Two Subsamples Represent the Same Universe: The German Socio-Economic Panel Study (SOEP) Experience

A wildly discussed shortcoming of panel surveys is a potential bias arising from selective attrition. Based on data of the German Socio-Economic Panel Study (SOEP), the authors analyze potential artifacts (level, structure, income inequality) by comparing results for two independently drawn panel subsamples started in 1984 and 2000. They apply ANOGI (analysis of Gini) techniques, the equivalent of ...

Sectoral Heterogeneity in the Employment Effects of Job Creation Schemes in Germany

Job creation schemes (JCS) have been one important programme of active labour market policy (ALMP) in Germany for a long time. They aim at the re-integration of hard-to-place unemployed individuals into regular employment. A thorough microeconometric evaluation of these programmes was hindered by the fact, that available survey datasets have been too small to account for a possible occurrence of effect ...

The Impact of a Customs Union between Turkey and the EU on Turkey's Exports to the EU

This article investigates Turkey's sectoral trade flows to the EU based on panel data from the period 1988 to 2002. Turkey's 16 most important export sectors are analysed. Emphasis is placed on the role of price competition, EU protection and transport costs in the export trade between Turkey and the EU. The empirical model used is an extended version of the gravity model. This study is also a contribution ...

An Empirical Analysis of Voluntary Payments for Information Goods on the Internet

This paper presents results from a field study on voluntary contributions for an information public good provided via the Internet (an electronic newsletter for authors). Whereas the standard private provision model predicts that individuals contribute less if other individuals contribute more, we find that readers are more likely to pay the more they expect others to give. This result is consistent ...

Taking "Don't Knows" as Valid Responses: A Multiple Complete Random Imputation of Missing Data

Incomplete data is a common problem of survey research. Recent work on multiple imputation techniques has increased analysts' awareness of the biasing effects of missing data and has also provided a convenient solution. Imputation methods replace non-response with estimates of the unobserved scores. In many instances, however, non-response to a stimulus does not result from measurement problems that ...

The Argentinean Currency Crisis: A Markov-Switching Model Estimation

In 2002, the Argentinean currency board came to a sudden and dramatic end. Although the country had been suffering from weak economic fundamentals for years, the timing and severity of the currency crisis surprised most observers. The present study analyzes the role of fundamentals and self-fulfilling speculation in the Argentinean crisis. Arguing within a theoretical model of a fixed exchange rate ...
