ALONSO NEIRA, Miguel A.; RALLO JULIAN, Juan Ramón  e  ROMERO ANIA, Alberto. El efecto de los impuestos a las transacciones financieras en la estabilidad de los mercados de capital. Un debate sin resolver. El trimestre econ [online]. 2013, vol.80, n.317, pp.207-231. ISSN 2448-718X.

This paper analyzes the current debate on the effectiveness and impact of financial transaction taxes (FTT). Despite their regular use in several G-20 countries, there remain unexplained many aspects related to their impact on the stability of financial markets. Thus, although the academic literature tends to agree on the adverse effects of FTT on the trading volume and the value of financial assets, this is not the case in relation to their impact on short-term and long-term price volatility, the price discovery process, and the informational efficiency of financial markets.

Palavras-chave : impuestos a las transacciones financieras; tasa Tobin; especulación financiera; volatilidad de precios; crisis financieras; modelos de agentes heterogéneos; controles de capitales.
