    Entry and Competition with Product Differentiation: The Case of Swedish Concentrated Markets
    (2020-07-10) Widell, Emil; Davidsson, Jakob; University of Gothenburg/Graduate School; Göteborgs universitet/Graduate School
    Empirical investigations into competitive behaviour on different markets is important since it does not exist one single theoretical model of competition. This thesis empirically investigates the competitiveness in a number of Swedish concentrated markets by leveraging the relationship between market entry and market size using the adjusted entry threshold framework developed by Schaumans and Verboven (2015). Compared to the standard entry threshold framework developed by Bresnahan and Reiss (1991), the adjusted entry threshold framework takes product differentiation into account and thus captures both market expansion and business stealing following entry of a new firm. The estimated entry thresholds allow us to make inferences on the degree and structure of competition. The three sectors we analyse are real estate agents, restaurants, and plumbers. We find that entry has a positive effect on competition and when taking market expansion into account we find that the magnitude of this effect increases. The largest effect for all sectors occurs when a market goes from monopoly to duopoly. These results are in line with previous studies.

    Ger Eurovision Song Contest en ökad turism?
    (2018-06-28) Hillawi, Adam; Widell, Emil; University of Gothenburg/Department of Economics; Göteborgs universitet/Institutionen för nationalekonomi med statistik
    Countries, regions and cities, often in great competition, seek to arrange large and expensive events. The economic efficacy of arranging these events is a question being debated in the political and academic world alike. The key argument often used, in support of hosting large events, is that the marketing effect for the hosting regions or cities will cause an increase in tourism and investments. The purpose of this paper is to, in light of the aforementioned debate, study the effect that the Eurovision Song Contest 2013, held in Malmö, had on nights spent in hotels by tourists in the host city. One of the methods used to study the effect of this event is a so-called “Difference-in-Difference” method that compares the difference before and after treatment in a treatment group and a control group. In addition to this, another method was used to identify a possible “structural break” in the growth rate after the treatment, by comparing the time trend before and after the event. The study seems to suggest a positive effect on tourism in Malmö, caused by ESC 2013, but some of the made assumptions are questionable, and the results are not generalizable to other events and cities.
