Ítem Competition policies for the internet market in Colombia: Impact on entrepreneurship(Academic Conferences and Publishing International Limited, 2019-01-01) Osorio A.M.; Rendón J.J.G.; Osorio A.M.; Rendón J.J.G.; Universidad EAFIT. Departamento de Economía y Finanzas; Estudios en Economía y Empresa (GEE)The internet is one of the most important services worldwide, its use and increase in coverage are between the main concerns of development agendas. These markets tend to be highly concentrated, and competition policies have few tools to differentiate between companies with market power or possible abuse of it. The development, innovation, and research in the technology and telecommunications sector is growing and is promoted by the government. There are many entrepreneurs that need broadband for their business; that is the main reason for studying this sector. In Colombia, the Organisation for Economic Cooperation and Development (OECD) made recommendations for the telecommunications market, including the Internet, to improve not only the indicators but also the policies. The competition policies for the internet market in Colombia generate an impact on consumers and of course on entrepreneurship. The competition policy is made for the companies that have direct contact with the final consumer, so the wholesaler can manage different prices and practices that can affect the final consumer but there is not a clear policy for them. The aim is to analyze the Internet market in Colombia between 2010 and 2015 in a theoretical and empirical way, what is the impact of vertical integration on companies, competition policies and especially in the entrepreneurship. In Colombia, 75% of the population lives in the urban area. According to data from the OECD, the gap in the use of information and communication technology (ICT) in large and small companies is high, only 20% of small medium enterprises (SMEs) are connected to the internet; this figure is low, given that 96.4% of companies in Colombia are microenterprises. The competition policy for the internet sector in Colombia is focused on regulating the retail market, which has direct contact with the end users of the service. It is common to hear that the superintendence of commerce, industry, and tourism has sanctioned an enterprise, but they still have a lot to do in the regulation of the wholesale market of the internet. The concentration of the internet market in Colombia has a clear impact in all the entrepreneurship because, compared with other countries, in Colombia is more expensive to work with internet so, this has an impact in innovation, research, and competition. © Proceedings of the 14th European Conference on Innovation and Entrepreneurship, ECIE 2019.

Departamento de Economía y Finanzas; Estudios en Economía y Empresa (GEE)The partial collapse of a building in Colombia caused severe damage to its structural components. An implosion was realized to induce the collapse of 50% of the deteriorated building. To evaluate the influence of the implosion on the remaining structure, a monitoring survey was realized using triaxial accelerometers. Time signals associated with ambient, seismic and forced vibration were obtained. A study of the records in the time and the frequency domain was made. The analysis of the information allowed determining some structural properties that were useful to calibrate the analytical model of the structure. © 2015, International Society for Structural Health Monitoring of Intelligent Infrastructure, ISHMII.

Departamento de Economía y Finanzas; Estudios en Economía y Empresa (GEE)The deregulation process in the EU electricity sector triggered strategic decisions that led to industry restructuring. This paper presents preliminary evidence of the impact of this process on investors, using event studies and estimation techniques such as least squares and GARCH. Our findings suggest three stylized facts: 1) regulatory reform in Europe was certainly accompanied by a takeover wave, as predicted by Mitchell and Mulherin (1996); 2) mergers and acquisitions had a positive impact on the stock price of target firms, and a much lower and sometimes even a negative impact for the bidding firms; 3) the effect of takeover announcements on the returns of competitors of the merging firms depends on the degree of market power. In countries with high market power (like Spain) competitors significantly increase share returns upon takeover announcements, whereas in countries with lower market power (like England and Wales) returns do not change significantly. © 2012 IEEE.Ítem Competition Policies for the Internet Market in Colombia: Impact in Entrepreneurship”(Conferences and Publishing International Limited ACPIL, 2019-09-19) Molina, A.; García, J.J.; Molina, A.; García, J.J.; Universidad EAFIT.
