Competencia espacial en el mercado colombiano de depósitos

Se analizan las condiciones competitivas del Mercado colombiano en una aproximación más desagregada para poder determinar si los resultados obtenidos en esta estimación son o no consistentes con los resultados obtenidos al analizar el mercado nacional en total.As Freixas and Rochet (1997) mention, in perfect competition the optimal choice for banks is determined by the point where intermediation margins are equal to operating costs. In this scenario, market equilibrium is not affected by a bank’s actions. In contrast, when a bank has market power, it can affect prices, which will lead to higher lending rates and lower deposit rates. In this way, part of the consumer surplus is passed to the banks and efficiency is lost through a reduction in the volume transacted on the market. Therefore, regulations to limit the creation, spread and use of market power are entirely justified. Nevertheless, the only guides to implementing such regulations in an ideal way are the empirical studies of competition that describe the characteristics of the relevant market, which is why they are so important
