Abstract
Los orígenes de la actual crisis global se encuentran en los malos incentivos y en la información asimétrica en el mercado hipotecario subprime norteamericano. Pero sobretodo refleja una visión matemática y mental de las "expectativas racionales" sustentada en supuestos irreales: información exenta de costos, disponible de manera inmediata y agentes con capacidad y tiempo ilimitado para procesar la misma perfectamente. Para evitar crisis futuras, es necesario incorporar conceptos socio- y psicológicos en el pensamiento económico como el hecho que las personas no podemos procesar toda la información, aplicamos reglas de comportamiento y somos reticentes al cambio, sobretodo en mercados financieros que son intrínsecamente inciertos.
