    My thesis consists of two relatively independent topics. In the first topic I empirically inves- tigate the factors that determine the presence of the independent coffee shops in the market of Central London. In the second topic I present a theory of cartel detection. The common feature of these topics is that I investigate the demand side effects on market structure and its impact on competition. To be more specific, in the first topic I build a simple theoretical model of product differentiation in adjacent markets, based on Mazzeo (2002). For the empirical estimation I have constructed a unique dataset of coffee shops in Central London. I further manage to identify differences on demand characteristics across markets by utilizing data on people’s mo- bility from the tube stations and provide evidence for the existence of product differentiation. It is found that residential areas with high employment, areas with small business density and leisure areas increase the profitability of the independent coffee shops. A counterfactual analysis is also presented. In the second topic I investigate the cartel’s strategies and likelihood of collusion when the buyers of the cartel are able to report its existence to the anti-trust authority. I char- acterize the cartel’s optimal behavior when the buyers are actively monitoring the cartel’s members and are able to report a cartel to an anti-trust authority1. I present a simple static model and I show that the likelihood of collusion increases as the willingness of the buyers to report increases (cost of reporting decreases). Furthermore, it is shown that it is optimal for an anti-trust authority to decrease the cost of reporting (a trade-off between price reductions in existing cartels and increased likelihood of cartel formation is identified). Finally, alterna- tive cartel strategies are also explored in this topic. As for the last point, I show that the threat of exclusion (foreclosure) and price discrimination are robust strategies that prevent buyers from reporting

    Algorithmic Pricing:The Current State of Affairs from a Law and Economics Perspective

    Get PDF
    The rise of algorithmic pricing has transformed perfect price discrimination from a theoretical concept into a real possibility. Through self-learning pricingalgorithms, a strategy can be developed that approximates consumers’ reservation prices with ever-improving accuracy. This paper analyzes algorithmic pricing from a law and economics perspective to identify the efficiency and equity effects that the practice could cause and determine to which extent it is regulated under the current legal framework. This paper finds that under competitive market conditions, algorithmic pricing could be welcomed from an efficiency perspective, but from an equity and ethical perspective serious concerns need to be raised. If these concerns are to be taken seriously, the legal framework provides only a partially functional approach to address algorithmic pricing. Additional appropriate remedies are, therefore, needed to protect consumers adequately and effectively against exploitation that reduces their welfare

    Downstream merger with oligopolistic input suppliers

    We examine how a downstream merger affects input prices and, in turn, the profitability of such a merger under Cournot competition with differentiated products. Input suppliers can be interpreted as ordinary upstream firms, or trade unions organising workers. If the input suppliers are plant-specific, we find that a merger is more profitable than in a corresponding model with exogenous input prices. In contrast to the received literature, we find that it can be more profitable to take part in a merger than being an outsider. For firm-specific input suppliers, on the other hand, results are reversed. We apply our model to endogenous merger formation in an international oligopoly, and show that the equilibrium market structure is likely to be characterised by cross-border merger. -- Wir untersuchen, inwiefern nachgelagerte Fusionen Inputpreise erhöhen und wie diese wiederum die Fusionen bei Cournot-Wettbewerb mit unterschiedlichen Produkten beeinflussen. Inputanbieter können als normale vorgelagerte Firmen oder als Gewerkschaften, die Arbeiter organisieren interpretiert werden. Wenn die Inputanbieter werksspezifisch sind, finden wir, daß eine Fusion profitabler ist, als in einem vergleichbaren Modell mit exogenen Inputpreisen. Im Gegensatz zur herkömmlichen Literatur finden wir, daß es profitabler sein kann an einer Fusion teilzunehmen, denn ein Außenstehender zu sein. FĂŒr firmenspezifische Inputanbieter andererseits, ist das Ergebnis umgekehrt. Wir wenden unser Modell auf endogene Fusionsformierung in einem internationalen Oligopol an und zeigen, daß die Gleichgewichtsmarktstruktur wahrscheinlich durch grenzĂŒberschreitende Fusionen gekennzeichnet ist.merger profitability,input suppliers,trade unions,cross-border merger

    A Special Meeting of Academic Board was held on 12 December 2019 in response to a requisition calling for the establishment of a Working Group ‘to advise on racism and prejudice that would investigate the proposed adoption of the IHRA definition of antisemitism and its consistency with/inconsistency with Academic Freedom at UCL’. Academic Board resolved at that meeting to set up a Working Group ‘to report to the Board so that it may advise Council on the matter of group-specific definitions of racism.’ Elections to the Working Group were accordingly held and the Working Group began its work in February 2020

    Innovation in the European chemical industry

    Firms in the European chemical industry have been among the most successful firms world wide. However, they have had to undertake severe restucturing in order to maintain their market position. These efforts focused in particular on strengthening their innovative capability as product and process innovation have become the most decisive factors in global competition. In order to improve the innovative conditions, the European Commission has supported the Community Innovation Survey (CIS). 1992/1993 was the first time that large-scale harmonised innovation surveys were carried out in all Member States of the European Union. This study uses the CIS micro data from nearly 2000 European chemical firms. This study focuses on the identification of innovative trends within the chemical industry between 1984 and 1993. Using data from annual reports of nine selected European stock companies, the study identifies those areas of the chemical industry currently having the highest innovative potential. Three speciality categories are identified as having the highest number of innovations during this ten year period: chemicals, paints/varnishes, and plastics. -- Obwohl viele europĂ€ische Unternehmen der chemischen Industrie in den vergangenen Jahrzehnten zu den erfolgreichsten in der Welt zĂ€hlten, mußten sie sich Anfang der neunziger Jahre einem gravierenden Strukturwandel unterziehen, um ihre Position behaupten zu können. Die FĂ€higkeit der Unternehmen, Innovationen hervorzubringen, stand und steht dabei im Mittelpunkt. Mit dem Ziel, die Rahmenbedingungen fĂŒr Innovationen zu verbessern, fĂŒhrte die EU-Kommission 1993 eine europaweite Innovationserhebung, den Community Innovation Survey (CIS) durch. In dieser Studie wurden die anonymisierten Antworten von nahezu 2000 Unternehmen der chemischen Industrie analysiert. Um Innovationstrends aufzuzeigen zu können, wurden darĂŒber hinaus GeschĂ€ftsberichte von neun großen europĂ€ischen Chemieunternehmen ausgewertet. So wurden die Sparten SpezialitĂ€ten, Farben/Lacke und Kunststoffe als diejenigen Sparten identifiziert, die im Untersuchungszeitraum (1984-1993) die meisten Innovationen aufwiesen.

    L'auteure Ă©tudie en un premier temps les diffĂ©rents recours offerts aux victimes de harcĂšlement sexuel au QuĂ©bec et les avantages qu’elles peuvent en tirer. Elle discute ensuite des poursuites en libelle diffamatoire intentĂ©es contre ces victimes qui sont parfois utilisĂ©es en guise de reprĂ©sailles aux plaintes de harcĂšlement sexuel. De son analyse dĂ©coule une critique des mesures de redressement octroyĂ©es aux victimes de harcĂšlement sexuel. L'analyse jurisprudentielle dĂ©montre que les montants accordĂ©s en matiĂšre de dommages moraux ne sont pas toujours adĂ©quats pour indemniser pleinement les victimes de harcĂšlement sexuel. Il y a lieu de croire que les tribunaux devraient prĂ©ciser mieux les facteurs utilisĂ©s pour quantifier les dommages moraux. L'octroi de mesures de redressement «proactives » pourrait peut-ĂȘtre aider davantage Ă  remĂ©dier au problĂšme du harcĂšlement sexuel en milieu de travail.The author studies different remedies available to victims of sexual harassment in Quebec and their advantages and disadvantages. She discusses the problem of actions for defamatory libel against victims of sexual harassment as a means of reprisal. Further, the author reviews the type and amount of damages awarded to victims of sexual harassment in Quebec decisions. The author concludes that the amounts awarded to victims of sexual harassment do not provide full compensation for the injuries caused by the harassment. She believes that tribunals should be more explicit and describe the factors used in quantifying moral damages. In order to fully deal with the problem of sexual harassment, tribunals should order pro-active measures against respondent employers and employees

    Die AttraktivitÀt von Handelsmarken-KÀufern : eine empirische Analyse und strategische Empfehlungen zur Vermarktung von Handelsmarken

    Full text link
    Im internationalen Vergleich ist der Marktanteil von Handelsmarken (bzw. Eigenmarken) im deutschen Lebensmitteleinzelhandel extrem hoch. Dies wird zwar stark durch den Erfolg des Discounters Aldi beeinflusst, doch auch im ĂŒbrigen Einzelhandel weisen Handelsmarken zum Teil ein betrĂ€chtliches Wachstum auf. Dieser Trend wird sich aller Erwartung nach fortsetzen. Als Motiv des Handelmarkeneinsatzes wird hĂ€ufig - neben dem Preiskampf gegen Discounter - die Profilierung der eigenen GeschĂ€ftsstelle genannt, die zur StĂ€rkung der Kundenbindung fĂŒhren soll. Aber sind HandelsmarkenkĂ€ufer tatsĂ€chlich geschĂ€ftstreuer? Dies ist eine von vielen Fragen, denen in der vorliegenden Studie nachgegangen wird. In dieser Untersuchung wird der deutsche HandelsmarkenkĂ€ufer anhand marketing-relevanter Merkmale analysiert. So lĂ€sst sich ein Eindruck gewinnen, ob HandelsmarkenkĂ€ufer aufgrund ihrer spezifischen Charakteristika ein attraktives Kundensegment darstellen. Hierzu werden Verbraucher auf Grundlage von Kassenzetteldaten - ergĂ€nzt durch eine schriftliche Befragung - zunĂ€chst in drei Gruppen mit unterschiedlicher Handelsmarken-KaufintensitĂ€t eingeteilt und anschießend mit einander verglichen. Die analysierten GrĂ¶ĂŸen umfassen u.a. die QualitĂ€tsbeurteilung von Handelsmarken, die Treue gegenĂŒber Marken und EinkaufsstĂ€tten, die Bedeutung von Preis und QualitĂ€t bei der Kaufentscheidung sowie die soziodemographischen Merkmale Alter, Geschlecht, FamiliengrĂ¶ĂŸe, Bildung und Einkommen. Im Ergebnis kann ein sehr prĂ€zises und stimmiges Bild des deutschen HandelsmarkenkĂ€ufers gezeichnet werden. Hieraus werden strategische Empfehlungen zum Umgang mit Handelsmarken abgeleitet

    Globalization and Labour in the Twenty-First Century

    Get PDF
    Globalisation has adversely affected working-class organisation and mobilisation; but international labour movement demobilisation is not necessarily an irreversible trend. Globalisation has prompted workers and their organisations to find new ways to mobilise. This book examines international labour movement opposition to globalisation. It chronicles and critically scrutinizes the emergence of distinctively new forms of labour movement organisation and mobilisation that constitute creative initiatives on the part of labour, which present capitalism with fresh challenges. The author identifies eight characteristics of globalisation that have proven problematic to workers and their organisations and describes and analyses how they have responded to these challenges since 1990 and especially in the past decade. In particular, it focuses attention on new types of labour movement organisation and mobilisation that are not simply defensive reactions but are offensive and innovative responses that compel corporations to behave more responsively and responsibly towards employees and society at large. This book will be of interest to students and scholars of globalisation, political economy, labour politics, economics, Marxism and sociology of work
