costs. The agency theory was used as the central theoretical analysis of the research. The study used 34
listed firms in the Nairobi Securities Exchange being firms that revealed consistency in the market
during the period 2006‐2012 giving a total of 238 firm‐year observation. The study used a linear
regression model to analyze data with the support of SPSS software. The results indicated that capital
structure was negatively and significantly correlated to agency cost (r = ‐0.464; p<0.01) at a 1% confidence
interval level. The study findings will be of valuable assistance to shareholders of listed firms in the
