How to Organize Sequential Auctions: Results of a Natural Experiment by Christie's

In empirical studies of sequential auctions of identical objects prices have been found to decline.We study auctions of ancient Chinese porcelain recovered from shipwrecks.In these auctions there are very long sequences of lots of identical objects.We find that the average price decline is smaller in long sequences.It is especially large for the first pair of lots auctioned; it is also larger when the price of the previous lot was larger than (the upper bound of the range of) the pre-sale estimate of the previous lot and when the number of items in lots that follow each other increases.As a consequence, it appears that sellers may have some control over the sequence of prices and therefore on their revenue.Our results point to the fact that a sequence of lots each of which contains the same number of items generates more revenue than lots with varying number of items.auctions;prices;estimation

Does it Pay to do Well in Competitions? The case of the Queen Elizabeth Piano Competition

Pianists who achieve high scores in the Queen Elizabeth musical competition are rewarded by subsequent success.It is not clear whether this is caused by the score itself or because those who have high scores are better pianists anyway. Since the timing and the order of appearance are good instrumental variables for the nal ranking, our data on eleven subsequent competitions make it possible to distinguish between the two alternative explanations.We find that high scores have an impact on later success.job performance;competition

Voting on the choice of core languages in the European Union

Copyright @ 2008 Elsevier B.V.Extensive multilingualism is one of the most important and fundamental principles of the European Union (EU). However, a large number of languages (currently 23) hinders communication and imposes substantial financial and legal costs. On the other hand, the reduction of the number of languages would disenfranchise some or many EU citizens. We use the results of a survey on languages and argue that even though a linguistic reform reducing the number of languages is unlikely to gain sufficient political support today, this may change in the future since young people are more proficient at speaking foreign languages

Disenfranchisement in linguistically diverse societies : the case of the European Union

We consider a linguistically diversified society and examine the notion of language disenfran-chisement when some individuals are denied the full access to documents and political process in their native tongues. To calculate the disenfranchisement indices we use the Dyen percentage cognate matrix of linguistic distances between Indo-European languages and apply survey and population data on language proficiency in the European Union. We then determine optimal sets of official languages that depend on society's sensitivity against disenfranchisement and comprehensiveness of the chosen language regime. We also discuss the language situation in the European Union after its last enlargement.We are grateful to the Alexander von Humboldt Foundation and Fundación BBVA for their financial supportPublicad

La disponibilité des diplômés universitaires sur le marché du travail québécois

Entre 1971 et 1981, il s’est produit une dégradation sensible de la situation du Québec, relativement à celle du Canada, en ce qui touche le nombre des diplômés universitaires au sein de la main-d’oeuvre. Des quatre grandes régions du Canada, c’est le Québec qui accusait le plus lent taux de croissance, tant par le nombre absolu de diplômés que par le nombre relatif de diplômés par millier de personnes dans la population active. Cette diminution relative de l’offre de diplômés universitaires au sein de la main-d’oeuvre québécoise avait deux causes. En premier lieu, les universités québécoises ont octroyé un nombre relativement faible de diplômés par rapport à la population d’âge universitaire. En second lieu, un nombre important de diplômés universitaires ont quitté la province. En effet, pour la période 1975-1981, on estime l’émigration nette des diplômés à quelgue 21 200, soit 19,6 % des diplômes conférés au cours de cette période. Étant donné l’influence qu’exercent les universitaires sur la croissance économique, dans les industries de haute technologie en particulier, il serait souhaitable que le gouvernement du Québec reconsidère les réductions qu’il se propose d’apporter aux budgets des universités

Linguistic Diversity and Its Impact on Economic Policies and Political Decisions

The paper addresses the issue of linguistic diversity and its impact on economic policy and political decisions. Importance of the topic is illustrated by examination of optimal sets of official languages in the European Union. It is shown that alternative estimation methods of language disenfranchisement alter the order in which the languages enter the list of the official ones. Also, we present an overview of gametheoretic models of language acquisition, where individuals weigh costs and benefits of studying new languages. These models are used to predict actual distribution of language skills in a society and to compare it with the first-best outcome. The paper ends with estimation of our predictions on the basis of empirical analysis of European data.Game theory, linguistic models, communication benefits, costs of studying, official languages of the European Union, Nash equilibrium, public efficiency
