Acceptability of the German Charging Scheme for Heavy Goods Vehicles: Empirical Evidence from a Freight Company Survey

While several European and national studies have dealt with the acceptability of road pricing schemes for passenger transport, only sparse research is available on this issue for freight transport. Against this background, the paper deals with the acceptability of the German road user-charging scheme for heavy goods vehicles by the road haulage industry. It presents the findings of an internet-based ...

Outward FDI and Domestic Investment in Two Industrialized Countries

Using cointegration techniques, we find that in the US, outward FDI has positive long-run effects on domestic investment. In Germany, this complementary relationship exists only in the short run. In the long run, outward FDI substitutes for German domestic investment.

Effects of Tariffication: Tariffs and Quotas under Monopolistic Competition

Recent rounds of GATT and later WTO have advocated widespread tariffication, meaning that existing non-tariff barriers be converted into import equivalent tariffs. From an economic point of view, the effects of such tariffication are not entirely clear. The paper presents a trade model with monopolistic competition to examine the welfare effects of tariffication. The ranking of pre- and post-tariffication ...

A Strategic Model of European Gas Supply (GASMOD)

This paper presents a model of the European natural gas supply, GASMOD, which is structured as a two-stage-game of successive natural gas exports to Europe (upstream market) and wholesale trade within Europe (downstream market) and which explicitly includes infrastructure capacities. We compare three possible market scenarios: Cournot competition in both markets, perfect competition in both markets, ...

Native-Migrant Differences in Risk Attitudes

This article questions the perceived wisdom that migrants are more risk-loving than the native population. We employ a new large German survey of direct individual risk measures to find that first-generation migrants have lower risk attitudes than natives, which only equalize in the second generation.

Beitragssatz, Kassenwettbewerb und Gesundheitsreform: eine empirische Analyse

The premium rates paid for statutory health insurance in Germany play a key role in the competition among health care funds. With the most recent health care reform (GKV-Wettbewerbsstärkungsgesetz GKV-WSG), a range of new products have been introduced that could erode the advantageous selling proposition of the premium rates. In addition to the pure monetary incentive to change health insurance provider, ...

Human Capital and Ethnic Self-Identification of Immigrants

Efficiency Analysis of East and West German Electricity Distribution Companies: Do the "Ossis" Really Beat the "Wessis"?

External Debt in Post-Conflict Countries

In the development literature, there exists no systematic study of external borrowing in post-conflict countries. We address this gap by analyzing statistical and case study evidence from three African countries. We find that many war-affected countries face rising debt arrears and deteriorating relations with creditors. Rebuilding trust between lenders and borrowers is hence a crucial but often slow ...

Using the Gravity Equation to Differentiate among Alternative Theories of Trade: Another Look

This study compares two alternative approaches - the traditional ordinary least square (OLS) and the Poisson Quasi Maximum Likelihood (PQML) procedures - to estimation of the home market effects for the heterogeneous, the reference priced and the homogeneous goods in the gravity model derived in Feenstra et al. (2001). Despite our findings that the PQML estimation results oftentimes (significantly) ...

On Estimating an Asset's Implicit Beta

A.F. Siegel (1995) has developed a technique with which the systematic risk of a security (beta) can be estimated without recourse to historical capital market data. Instead, beta is estimated implicity from the current market prices of exchange options that enable the exchange of a security against shares on the market index. Because this type of exchange options is not currently traded on the capital ...

The Excess Demand for Subsidized Child Care in Germany

The extension of publicly provided or subsidized child care is currently one of the priorities of the political agenda in many European countries. In this article, the excess demand for subsidized child care slots in Germany is estimated using a partial observability model. The results show that there is considerable excess demand for child care for children aged less than 3 years in East and West ...

Modeling Structural Change: An Application to the New EU Member States and Accession Candidates

The rapid changes in the transition economies must be evaluated in a comparative context. This paper provides a comprehensive comparative analysis using a large panel data set of market economies as a reference point. We wish to establish the extent and speed with which the structures of the transition economies converge toward other country groups, ranked according to income levels. The exercise provides ...

Why Are Mothers Working Longer Hours in Austria than in Germany? A Comparative Microsimulation Analysis

Labour force participation rates of mothers in Austria and Germany are similar; however, full-time employment rates are much higher among Austrian mothers. In order to find out to what extent these differences can be attributed to differences in the tax-transfer system, we perform a comparative microsimulation exercise. After estimatingstructural labour supply models for both countries, we interchange ...
