Las crisis bancarias en países emergentes: Caso Latinoamérica Bernardo Bernardi Carriello Administración y Contabilidad Crisis bancarias flujos de capital contagio financiero vulnerabilidad financiera crisis de balanza de pagos En la década de los noventa se registraron diversos episodios de tensión ycrisis financiera en todo el mundo. En estos episodios han estado involucradostanto los sistemas financieros domésticos, como el mercado de monedaextranjera y de deuda interna y externa. De otra parte, las crisis bancariashan sido más frecuentes en las dos últimas décadas que en los años anteriores.La ocurrencia de estos eventos ha suscitado, consecuentemente, un ampliovolumen de investigación conceptual y empírica. Este trabajo tuvo dos finalidades:Primero, presentar de manera sintética los resultados más relevantespara la política económica, y segundo, discutir mecanismos mediante loscuales la política de regulación y supervisión podría utilizar estos resultadosde manera productiva. 2006 artículo científico 1657-6276 https://www.redalyc.org/articulo.oa?id=64602106 es http://www.redalyc.org/revista.oa?id=646 Pensamiento & Gestión application/pdf Universidad del Norte Pensamiento & Gestión (Colombia) Num.21
