Sample attrition in the RLMS, 2001–10

The data of the Russian Longitudinal Monitoring Survey (RLMS) – Higher School of Economics represents one of the few nationally representative sources of household and individual data for Russia. These data have been collected since 1992 and in recent years, thanks to more secure financial and logistical support, have become a resource increasingly drawn upon by scholars and students for national and cross-national studies. In this paper, we examine the extent of non-random attrition in the RLMS and discuss the circumstances under which this might give rise to biases in econometric analysis. We illustrate this with an example drawn from the health sphere.     

The Empire Strikes Back: Digital Control of Unfair Terms of Online Services

The authors argue that it is possible to partly automate the process of abstract control of fairness of clauses in online consumer contracts. The authors present a theoretical and empirical argument for this claim, including a brief presentation of the software they have designed. This type of automation would not replace human lawyers but would assist them and make their work more effective and efficient. Policy makers should direct their attention to the potential of using algorithmic techniques in enforcing the law regarding unfair contractual terms, and to facilitating research on and ultimately implementing such technologies.     

Good practices on cost – effective road infrastructure safety investments

The paper presents the findings of a research project aiming to quantify and subsequently classify several infrastructure-related road safety measures, based on the international experience attained through extensive and selected literature review and additionally on a full consultation process including questionnaire surveys addressed to experts and relevant workshops. Initially, a review of selected research reports was carried out and an exhaustive list of road safety infrastructure investments covering all types of infrastructure was compiled. Individual investments were classified according to the infrastructure investment area and the type of investment and were thereafter analysed on the basis of key safety components. These investments were subsequently ranked in relation to their safety effects and implementation costs and on the basis of this ranking, a set of five most promising investments was selected for an in-depth analysis. The results suggest that the overall cost effectiveness of a road safety infrastructure investment is not always in direct correlation with the safety effect and is recommended that cost–benefit ratios and safety effects are always examined in conjunction with each other in order to identify the optimum solution for a specific road safety problem in specific conditions and with specific objectives.     

Estimating the Equilibrium Effective Exchange Rate for Potential EMU Members

In this study, we attempt to examine the possibility of emergence of significant fluctuations of the exchange rates in the future for the candidate EMU countries. In doing so, we estimate the equilibrium rate of the nominal effective exchange rate for Poland, Hungary, Slovak Republic and Malta through the BEER and PEER approaches. While the PEER-based estimation implies a large misalignment rate for the Hungarian forint, the BEER-based analysis shows that the present exchange rates of the countries considered do not deviate significantly from their equilibrium rates. As a consequence, based on BEER analysis, we do not expect large fluctuations in the effective exchange rates among the currencies considered. Hence, the relevant effective exchange rates are expected to be relatively stable. As a matter of fact, the entry of those countries into EMU is not expected to weaken the stability of Euro.

Nonlinear Exchange Rate Adjustment in the Enlarged Eurozone: Evidence and Implications for Candidate Countries

This paper sheds light on the importance of the validity of PPP hypothesis for the accessing process of the candidate countries towards EMU. The evidence of nonlinear adjustment in real exchange rates suggests the estimation of a nonlinear SETAR model. While linear half‐life estimates are biased upward (five years on average), SETAR half‐life estimates imply a faster reverting process (1.5 years on average). Moreover, we found that TPI‐based real exchange rates are more appropriate than CPI‐based real exchange rates in testing for PPP hypothesis. For the cluster of EMU countries and for the pre‐EMU period, our nonlinear model confirms stationarity for the majority of the TPI‐based real exchange rates with half‐life estimates less than a year.     

Copyright, Parallel Imports and National Welfare: The Australian Market for Sound Recordings

For more than a decade now there has been considerable, often heated, debate over the issue of the parallel importation of sound recordings into Australia. Citing anti-competitive monopolistic distribution, an increasingly integrated global market and the challenges of new technologies, the Australian government recently passed the Copyright Amendment Act (No.2) 1998 , which permits the parallel importation of 'non-infringing' copies of a sound recording. This paper investigates the economic rationale underpinning this regulatory change and, using a partial equilibrium model, attempts to measure the likely welfare effects on consumers, copyright owners and the nation. In addition the paper examines the likely welfare impact of piracy within the new regulatory framework. This paper demonstrates that in a global music market characterised by exclusive territorial licences and price discrimination, the removal of parallel import restrictions by a small net-importer of intellectual property may be welfare enhancing for the nation. This welfare gain is at the expense of largely foreign copyright owners.     

Experience from a multivenue program to increase the use of car restraints in Greece

Objectives To evaluate a multivenue educational campaign aimed at increasing the use of car restraints in Greater Athens, Greece. Methods From October 1997 to June 1998, the campaign was implemented by a road safety coalition comprising 50 governmental and non-governmental organizations, while during the same period, seat belt law enforcement was not intensified. A pre-intervention survey was conducted in the summer of 1996 among the occupants of 1400 passenger cars and a post-intervention survey was carried out in the summer of 1998 (2250 cars). Both surveys followed the same protocol, focusing on the availability and use of seat belts. The data from the two surveys were modeled through multiple logistic regression. Results The odds ratio of seat belt use was significantly higher in 1998 than in 1996 (1.8 with 95% confidence interval = 1.5-2.1). Improvement was evident in highway traffic and among 25-64 year-old car occupants, but it was minimal among rear seat passengers, younger occupants, and in low-speed city and suburban traffic. There is evidence from the 1998 surveys that among front seat occupants, those travelling in larger engine capacity cars, frequently equipped with airbags, were less likely to use seat belts, whereas seat belting was more frequent among occupants of newer car models. Conclusion An education and information campaign in a Southern European country resulted in increased prevalence of seat belt use. A more intensive and sustained effort is required, however, to increase seat belt use in low-speed traffic and among rear seat occupants.
