At the beginning of their career civil servants in Germany can choose between the social health insurance (SHI) system and a private plan combined with a direct reimbursement of the government of up to 70 percent. Most civil servants chose the latter, not only but also because they have to cover all contribution payments in the social system themselves, while normal employees get nearly 50 percent from their employers. The city state of Hamburg decided to change the system by paying a share of the contributions if civil servants choose the social plan. We use a stochastic microsimulation model to analyse which socio-economic types of civil servants could benefit from the Hamburg plan and if this changes the mix of insured persons in the SHI system. Our results show that low income and high morbidity types as well as families have a substantially higher incentive to choose SHI. This reform might thereby increase the adverse selection of high risk cases towards SHI.
Bericht 2017/2018
(2018)
This paper employs event study methods to evaluate the effects of ECB’s nonstandard monetary policy program announcements on 10-year government bond yields of euro area member states. It covers data from 11 euro area countries from January 1, 2007 to August 31, 2017 and distinguishes between the more solvent countries (Austria, Belgium, Finland, France, Germany, the Netherlands) and the less solvent ones (Greece, Ireland, Italy, Portugal, Spain). The paper makes three contributions to the literature. First, it is the first paper to reveal that measurable effects of announcements arise with a one-day delay meaning that government bond markets take some time to react to ECB announcements. Second, it quantifies the country-specific extent of yield reduction which seems inversely related to the solvency rating of the corresponding countries. The reduction of the spread between both groups in response to an event is due to a stronger decrease in the less solvent group. Third, this result is confirmed by letting the announcement variable interact with the spread level, which is an innovation in this strand of literature. By employing different data as control variables, it turns out that the results are robust for a given event set.
E.ON SE intends to acquire Innogy SE from its competitor RWE AG based on a comprehensive exchange of business activities. The acquisition was announced in the first quarter of 2018 and is expected to be finalized late 2019. Next key milestones are the closing of a public takeover offer to minority shareholders and the approval of relevant antitrust and regulatory authorities. On the one hand, the merger will directly affect existing structures in the German energy market, helping both companies, E.ON and RWE, to significantly strengthen their respective core businesses. On the other hand, however, potential disadvantaged parties include Innogy itself, employees, municipalities and end customers.
Deal Logic Linde / Praxair
(2018)
Currently in news for the last moment approval from the Federal Trade Commission to make the Praxair and Linde merger a reality, the development of the deal has not been short of hurdles. Initially, Praxair-Linde faced resistance from the European Union under the accusation that the merger would hinder competition. Later, both companies had to undertake multiple selling transactions to meet the anti-trust requirements of the countries in which they operated. Praxair and Linde were finally able to meet the requirements in early November for a successful completion of the merger.
Linde and Praxair, the world’s no. 2 and no. 3 industrial gas suppliers respectively, were in the spotlight due to the size of the merger and the impact that it would have on the gas industry, almost making them a monopoly firm.
In the transformation driven by technology and stream-video challenges, media giants have taken acquisition strategies to uphold their current status and seek for vertical business expansion via entering content creation area. AT&T, the telecom and media giant, initiated an acquisition of Time Warner in October 2016 at a bid of USD 85bn, which was considered as the biggest M&A deal that year worldwide. But the process was blocked mainly by the US Department of Justice (DOJ) and stagnant for nearly 2 years. In June 2018, the vertical merger was approved by the U.S. District Judge and completed on 14.06.2018. Concerns about legitimate regulation should be largely taken into account of the evaluation of success of acquisitions.
We analyze the effects of limited feedback on beliefs and contributions in a repeated public goods game setting. In a first experiment, we test whether exogenously determined feedback about a good example (i.e., the maximum contribution in a period) in contrast to a bad example (i.e., the minimum contribution in a period) induces higher contributions. We find that when the type of feedback is not transparent to the group members, good examples boost cooperation while bad examples hamper it. There is no difference when the type of feedback is transparent. In a second experiment, feedback is endogenously chosen by a group leader. The results show that a large majority of the group leaders count on the positive effect of providing a good example. This is true regardless whether they choose the feedback type to be transparent or non-transparent. Half of the group leaders make the type of feedback transparent. With endogenously chosen feedback about good examples no difference in contributions can be observed among transparent and non-transparent feedback selection. In both experiments feedback shapes subjects’ beliefs. With exogenously chosen feedback, transparent feedback tends to reduce beliefs when good examples are provided as feedback and tends to increase beliefs in when bad examples are provided as feedback compared to the respective non-transparent cases. Our results shed new light on the design of feedback rovision in public goods settings.
