“…Based on their theoretical framework of exit and voice competition, Hendrick, Wu, and Jacob (2007) suggest that if mobility (exit) is the primary driver of the observed fiscal com petition, then one might find tax competition among municipal governments for taxes levied on highly mobile tax bases (like the ICA business tax in Colombia). Conversely, if the ac countability (voice) mechanism is the primary driver, then competition should be greater among municipal governments for the taxes that are more visible and salient to voters and other taxpayers than other types of revenue sources, such as, at the local level, property taxes (Bahl and Linn, 1998;Bird and Slack, 2004;Bahl, Martínez-Vázquez, and Youngman, 2010).…”
