This study investigates the endogenous determination of firm
efficiency and leverage while testing the competing hypotheses of agency
cost, efficiency-risk and franchise-value, in a sample of 136
non-financial firms listed on the Pakistan Stock Exchange (PSX), over
the period 2002 to 2012. Data Envelopment Analysis (DEA) method is
employed to measure firm efficiency as proxy for firm performance. The
endogenous nature of firm efficiency and leverage allowed using
two-stage least square (2SLS) technique. The findings of the efficiency
equation suggest that leverage has a significant positive effect on firm
efficiency. Additionally, firm risk, growth rate, size, board size and
board composition positively affect firm efficiency. On the other hand,
the results of the leverage equation suggest that firm efficiency has a
significant negative effect on leverage. Firm size and CEO duality have
positive effects on leverage while firm age, board composition,
institutional ownership, managerial ownership and asset tangibility have
negative effects on leverage. Generally, the results support agency cost
and franchise-value hypotheses that higher leverage improves firm
efficiency while higher firm efficiency results in reduced leverage.
