Spanish Abstract: Las ciudades de Colombia mantienen indices altos de delito a pesar del aumento del gasto en defensa y seguridad. Este trabajo propone y analiza la provision de informacion como una estrategia de bajo costo que puede ser efectiva para la disuasion del crimen. Para mostrar su efectividad, desarrollamos un juego dinamico con informacion imperfecta entre Autoridad y Criminal. En este juego la Autoridad debe decidir si asignar o no un policia a un area determinada y si enviar o no una senal. Por su lado, el Criminal solo observa la senal y debe decidir si comete el crimen o no. Si decide cometerlo sera atrapado unicamente si un policia esta presente. Uno de los equilibrios muestra que el uso adecuado de la senal puede desincentivar el crimen a traves de una mayor percepcion de captura sin incurrir en altos costos como el incremento del pie de fuerza.

摘要:尽管国防和安全支出增加,哥伦比亚城市的犯罪率仍然很高。在这一过程中,信息的提供被认为是一种有效的威慑犯罪的低成本战略。为了证明它的有效性,我们开发了一个动态游戏,在权威和罪犯之间有不完美的信息。在这个游戏中,当局必须决定是否将警察分配到一个特定的区域,以及是否发送信号。另一方面,罪犯只看信号,必须决定是否犯罪。如果他决定这样做,他只有在有警察在场的情况下才会被抓住。其中一种平衡表明,正确使用信号可以通过提高捕获感知来阻止犯罪,而不会产生增加力量脚等高成本。尽管政府在国防和安全方面的支出有所增加,但哥伦比亚的城市犯罪率仍然很高。本文件提出并分析了提供信息作为一项可有效减少犯罪的低成本战略。为了证明它的有效性,我们开发了一个动态游戏,在一个权威和一个潜在的犯罪之间有不完善的信息。assign当局决定是否对办案or not and to送a signal是否or not。刑事only注意The signal and必须决定是否to commit The crime or not。如果他决定犯罪,他将被逮捕,除非有一个警察。其中一项平衡方案表明,适当使用信号可以通过提高捕获感知来阻止犯罪,而不需要增加警察人力等高昂费用。我们还报告了不同发展阶段的平衡。
