Public Support for a Ban on Headscarves: A Cross-National Perspective

This paper compares a psychological explanation of support for a ban on headscarves in the United Kingdom, France, Germany and the Netherlands. This study examines how perceptions of threat posed by Muslims and Islam and the overall attitude towards Muslims explain support for a ban on headscarves. In addition, cross-national comparisons are made to study how these relations are affected by contextual differences. Analyses are based on the 2005 survey on Islamic extremism by the Pew Research Center. Results show that the countries have a large influence on whether someone supports the ban on headscarves, indicating that contextual differences matter. In addition, having a negative attitude towards Muslims makes it more likely to support a ban on headscarves. In general, perceived threat contributes to stronger support, although there are slight differences in effect between the countries. Finally, perceived threat equally influences support for the ban on headscarves among prejudiced and non-prejudiced people

Internet Retailing as a Marketing Strategy

We analyze the incentives for incumbent bricks-and-mortar firms and new entrants to start an online retail channel in a differentiated goods market. To this end we set up a two-stage model where firms first decide whether or not to build the infrastructure necessary to start an online retail channel and then compete in prices using the channels they have opened up. Consumers trade-off the convenience of online shopping and the ease to compare prices, with online uncertainties. Without a threat of entry by a third pure online player we find that for most parameter constellations firms' dominant strategy is not to open an online retail channel as this cannibalizes too much on their conventional sales. As the cannibalization effect is not present for a pure Internet player, we show that these firms will start online retail channels under a much wider range of parameter constellations. The threat of entry may force incumbent bricks-and-mortar firms to deter entry by starting up an Internet retail channel themselves. We also show that a low cost of building up an online retail channel or online shopping conveniences may not be to the benefit of online shopping as the strategic interaction between firms may be such that no online retail channel is built when the circumstances seem to be more favourable

Essays on Internet and Information Economics

In the last decade we have witnessed advances in information and communication technologies. These ICTs play a central role in the world economy: the rise of the Internet has facilitated the dissemination of information, while technological progress at the same time enhances the acquisition of information, for example in health care. Nevertheless, information processing is still bound by human nature, and the ease by which one economic agent can nowadays contact another may overload the latter. Other limitations include the fact that not everything of value can be digitalized, that exchange via Internet is indirect and disclosure of personal information may enable discrimination. The impact of these technologies on society is therefore equivocal. This book consists of five essays that each discuss some of the above issues and their impact on markets, with applications to e- commerce, insurance and the competition for attention

De mechanismes van algoritmische collusie

De populariteit van zelflerende algoritmes heeft zorgen gewekt bij academici en mededingingstoezichthouders over het mogelijk prijsverhogende effect van algoritmes voor prijszetting. Experts waarschuwen dat zelflerende algoritmes stilzwijgend zouden kunnen samenspannen en hogere prijzen kunnen bewerkstelligen (colluderen). Aan de andere kant zijn er auteurs die stellen dat coördinatie zelfs voor algoritmes te complex is om zonder verboden informatie-uitwisseling te bereiken. Wij overbruggen het gat tussen theoretische zorgen en dit praktisch scepticisme. In dit artikel analyseren wij mechanismes die ervoor zorgen dat zelflerende algoritmes in een setting met concurrentie relatief hoge prijzen kunnen bereiken, met een onderscheid tussen vorming en stabiliteit van stilzwijgende samenspanning. We analyseren de praktische toepasbaarheid van deze mechanismes. Stabiliteit-bevorderende mechanismes kunnen vóórkomen, maar we vinden het minder aannemelijk dat ook de prijsverhogende mechanismes in de praktijk kunnen worden gerealiseerd, vanwege de aanzienlijke kosten van experimentatie met prijzen, die essentieel is voor deze mechanismes. We concluderen dat het gebruik van AI (Artifical Intelligence) voor prijszetting mechanismes biedt die het risico op algoritmische collusie verhogen, maar de praktische belemmeringen betekenen dat het risico op dit moment beperkt lijkt te zijn tot specifieke markten of samenloop van omstandigheden

Flexible copyright: the law and economics of introducing an open norm in the Netherlands

This study analyses the law and economics of introducing flexibility in the system of exceptions and limitations in Dutch copyright law. Such flexibility would exist in an open norm, on the basis of which the courts can decide whether certain uses of copyrighted material are permissible or not, instead of explicitly defining this in the law. First, it assesses problem areas where the lack of flexibility creates legal disputes and potential barriers to innovation and commercialisation. Second, it analyses the economic rationale and economic effects of introducing flexibility. The study was commissioned by the Dutch Ministry of Economic Affairs, Agriculture & Innovation. Research methods used are literature review and in-depth interviews. The study includes a case study of Israel, where a fair use exception was introduced in the Copyright Act in 2007. Exceptions and limitations in the current copyright system are meant to balance the protection granted to rights owners with the public interest’s need to make certain unauthorized uses. However, this report identified a number of situations that do not fit well within the current set of exceptions and limitations and attributes this to a lack of flexibility. Among these uses are the activities of search engines, the use of works in User Created Content, cloud computing, data mining, distance learning, and transformative uses by, for instance, documentary filmmakers. Several of these problem areas have given rise to court proceedings with varying outcomes. The interpretation given by courts to existing exceptions and limitations - such as the quotation right, the exception for transient and incidental copying, the private copying exception, and the incidental use exception - is usually too narrow to respond to new technological developments, new developments in the creation process, or new commercialisation models. These types of uses generally do not ‘fit’ the narrowly defined exceptions and limitations and therefore lack legal basis. The same is true for things not yet invented. Because the law is not flexible in itself, courts have increasingly found inventive ways to create legal space for uses that are not covered by the exhaustive list of exceptions. In these cases flexibility with specific evaluation criteria could have been more satisfactory from a legal perspective. Flexibility could be obtained by introducing an open norm in the copyright system. This report defines such an open norm for the purpose of analysing the effects of more flexibility in copyright law. The norm has two main properties. First, it would coexist with the exhaustive list of exceptions and limitations in the current Dutch Copyright Act. Second, a use of a work would only benefit from the open norm if it passes the so-called three-step test, which takes the interests of the author or right holder into account. The first category of economic effects of introducing an open norm is that for some known uses that otherwise require licensing, the open norm would allow unlicensed use. Thispotentially reduces the reward to the creator of a work and therefore decreases the incentive to create. By contrast, it is also likely to reduce the creator’s costs of using another work as an input when producing a new work, and therefore to increase the incentive to create. It is difficult to predict which of these two opposing effects ultimately turns the scale in specific markets. Traditional creators generally worry about the negative effect on their reward and seem to believe that the first effect dominates. For businesses that use large numbers of protected works as an input for their services, such as Google, the opposite is true. They emphasise the benefits of reduced input costs and are likely to improve their legal position with an open norm. Collective rights management organisations in turn fear that their bargaining power vis-à-vis users like UCC-platforms, such as YouTube, would suffer from an open norm. However, given the design of the open norm, it is unlikely that rewards for creators are significantly affected. The application of the open norm by the courts tests for adverse effects on the business model of the rights holder (the previously mentioned three-step test). In case of severe adverse effects on the rights holder, the open norm does not apply. The shift in bargaining power from rights holders to user (platforms) is limited to cases that are currently licensed and where parties are sufficiently confident that the use benefits from the open norm. The second category of economic effects of introducing an open norm is that the legal delineation between infringement and permissible use becomes capable of accommodating developments in technology and society. This enables entrepreneurs to develop new products and services that rely on currently unforeseen use of protected material. On the downside, flexibility may reduce legal certainty in the short run, until jurisprudence on the practice of flexible copyright has developed. The countries that have recently introduced an open norm in their copyright laws have not produced any ex-ante or ex-post studies on the magnitude of these economic effects. The case study of fair use in Israel shows that the change may decrease legal certainty in the short run (as case law needs time to develop), but improve legal certainty in the longer run, as the legal position of acts that do not ‘fit’ a rigid system with an exhaustive list of static exceptions is being clarified. In sum, the main effects of introducing an open norm seem to be of a legal nature: it changes the legal position of some businesses and therefore affects the costs these businesses make to comply with copyright. ‘Tomorrow’s inventions’ are likely to be facilitated by an open norm. Since most businesses seem currently not chilled by the lack of flexibility, the effect on products and services available in the market is likely to be secondary to the legal effects
