Se analizan diferentes alternativas para la financiación de la educación superior, teniendo en cuenta que la presencia de fallas de mercado -tanto por el lado de la demanda como por el de la oferta- hace de éste un sector muy particular. Las primeras se relacionan con las decisiones privadas en términos de educación de la población estudiantil, y las segundas con las asimetrías de información que caracterizan el lado de la oferta en el financiamiento de la educación. El documento hace una revisión de literatura académica y de algunas experiencias internacionales sobre las diferentes fuentes de financiación en este sector, así como sus potenciales efectos sobre ciertas variables. Así, esta revisión arroja luces sobre las alternativas para el caso Colombiano.

I test the presence of hidden information and action in the automobile insurance market using a data set from several Colombian insurers. To identify the presence of hidden information I find a common knowledge variable providing information on policyholder s risk type which is related to both experienced risk and insurance demand and that was excluded from the pricing mechanism. Such unused variable is the record of policyholder s traffic offenses. I find evidence of adverse selection in six of the nine insurance companies for which the test is performed. From the point of view of hidden action I develop a dynamic model of effort in accident prevention given an insurance contract with bonus experience rating scheme and I show that individual accident probability decreases with previous accidents. This result brings a testable implication for the empirical identification of hidden action and based on that result I estimate an econometric model of the time spans between the purchase of the insurance and the first claim, between the first claim and the second one, and so on. I find strong evidence on the existence of unobserved heterogeneity that deceives the testable implication. Once the unobserved heterogeneity is controlled, I find conclusive statistical grounds supporting the presence of moral hazard in the Colombian insurance market.
