And as far as the legislation of banks it only is of application to banking companies, thus is clear that it deserves the corresponding studies, to increase to the field of application of the law to all the societies through a law all this within the Peruvian right. 14. POSTER the poster is an assumption of enterprise concentration, which has deserved really few studies in the Peruvian right. Thus we recommended its study on the part of the treaty writers, that are those that creates doctrine, so that it spreads on the part of the legal operators. The poster happens between companies, therefore, is not exclusive of the societies, nor of no other type of company, in such sense exists poster of societies, poster of individual companies of limited responsibility, poster of cooperatives, poster of communal companies, poster of industralists who exert the company like natural people, among others. The poster is not defined in the Peruvian legislation, therefore, is clear that its corresponding regulation deserves to have major legal security in the same, since is not recommendable in these cases of going to other sources or parts or elements of the right. In such sense we hoped in the future not very distant to count in the Peruvian state with a legislation on the enterprise posters or karteles, of such form that looks for major facility the economic agents to invest in a more and more competitive market as it is the Peruvian market. In the doctrine we found abundant definitions of poster, thus we were sent the same to have solids knowledge straight exceeds enterprise or right of the businesses or right of the company, in a market like in the Peruvian that exists little information on this branch of the right. What the poster looks for is to maintain the autonomy of the companies but to occupy the market, in such sense if for example a poster of companies is constituted that make soda waters is clear that they are possible to be occupied the market, with a view to its domination.
