It is revealed that a firm's constrained credit status changes with the improvement of its efficiency. The results further reveal that financially constrained firm's investment is comparatively more sensitive to cash flow, but this sensitivity is negatively and significantly related with corporate efficiency. These results point to the fact that high investment sensitivity to cash flow may not be solely driven by measurement error in investment opportunity, but may still be interpreted as a consequence of imperfect substitutability between internal and external financing arising from the capital market imperfections.JEL Classification: C34, D92, G14, L21

Purpose – Using a panel of 1,122 UK firms listed on the London Stock Exchange over the period of 1981-2009, corporate efficiencies are predicted in this paper as inverse proxies of agency cost and the agency cost hypotheses are tested. The paper aims to discuss this issue. Design/methodology/approach – Stochastic frontier analysis is used to estimate corporate efficiency of firms, but from two different perspectives. The long-run and short-run corporate efficiencies are predicted focussing on modern approach of value maximization and traditional approach of profit maximization, respectively. Findings – The estimation results reveal that, an average firm in the sample achieves 74.5 percent of its best performing peer's market value and 86.6 percent of its best performing peer's profit and both of them are highly significant in the analysis. The long-run market value efficiency supports the agency cost of outside equity and the short-run profit efficiency supports the agency cost of outside debt hypothesis. Also there is a positive rank correlation between these two efficiencies which confirms that an average firm in the UK suffers from inefficiency or agency conflicts to a certain extent, no matter whether the firm is driven by short-run or long-run growth perspectives. Research limitations/implications – The predicted broad measures of agency costs in the paper have wider implications in enhancing the understanding of the UK firms’ corporate performance especially when they operate under a relatively free and market based governance and financial system. Originality/value – The work is distinguished by the large panel of UK firms and a long period of time that is considered. Emphasizing on the empirical implications of the distinctions between short-run and long-run efficiency is also novel.

Differential quantitative effects of internal finance on growth among firms facing different degrees of financial constraints are found in this paper using an unbalanced panel data on 1122 UK firms listed on the London Stock Exchange. The generalized methods of moments (GMM) estimation results are consistent with financial constraints arising from capital market imperfections and indicate a substantially greater sensitivity of growth to cash flow for firm years facing the most binding financial constraints. Furthermore, these firms can actually expand their size more than the extent of increase in cash flow they may have which supports the leverage effect hypothesis. The estimated impact decreases monotonically thereafter as financial constraints become less binding allowing the firms to finance successively bigger portion of their growth through external financing.
