Resumen:
his study provides a test and analyses the existence and magnitude of sticky costs in an emerging economy s financial sector. The results use data from Argentinean banks between 2005 and 2010 total costs increase 0.55 for every 1 total income increase and decrease only 0.13 per 1 total income decrease and show that the sticky cost magnitude is similar but more pronounced than those documented in previous studies, both in central economies Anderson et al., 2003; Calleja et al., 2006 and in emerging economies Ribeiro de Medeiros and de Souza Costa, 2004. This kind of analysis absence from Latin-American companies financial sectors, particularly those in Argentina, is one of the main characteristics of this study.Its main contribution to the literature is the topic s novelty and its empirical validation in a G20 emerging economy s financial sector.
