The Impact of Managerial Entrenchment on Agency Costs: An Empirical Investigation Using UK Panel Data

This paper empirically investigates the relationship between managerial entrenchment and agency costs for a large sample of UK firms over the period 1999-2005. To measure managerial entrenchment, we use detailed information on ownership and board structures and managerial compensation. We develop a managerial entrenchment index, which captures the extent to which managers have the ability and incentives to expropriate wealth from shareholders. Our findings, which are based on a dynamic panel data analysis, show that there is a strong negative relationship between managerial entrenchment and our inverse proxy for agency costs, namely asset turnover ratio. There is also evidence that short-term debt and dividend payments work as effective corporate governance devices for UK firms. Finally, our findings reveal that agency costs are persistent over time. The results are robust to a number of alternative specifications, including varying measures of managerial entrenchment and agency costs.

Managerial incentives and corporate leverage: evidence from the United Kingdom

This paper investigates the effect of managerial incentives and corporate governance on capital structure using a large sample of UK firms during the period 1999–2004. The analysis revolves around the view that managerial incentives are important in determining a firms leverage. However, we argue that the exact impact of these incentives on leverage is likely to be determined by firm-specific governance characteristics. To conduct our investigation, we construct a simple corporate governance measure using detailed ownership and governance information. We present evidence of a significant non-monotonic relationship between executive ownership and leverage. There is also strong evidence suggesting that corporate governance practices have a significant impact on leverage. More importantly, the results reveal that the nature of the relation between executive ownership and leverage depends on the firms corporate governance structure.

Board Independence, Audit Quality and Earnings Management: Evidence from Egypt

Using a unique dataset for Egyptian firms, we investigate the relationship between board independence, audit quality and earnings management. We test whether firm-level corporate governance provisions matter in an emerging market setting characterised by weak legal enforcement and inadequate external discipline by the market for corporate control. Our results cast doubt on the notion that a higher ratio of non-executive members is associated with lower earnings management. We find that the effect of board independence on earnings management practices is contingent on the levels of ownership held by executive directors and large shareholders, as well as the composition of audit committee. In addition, the results are consistent with the view that high-quality auditors are effective in reducing earnings management. JEL Classification: M41, M48

Informative content of insider purchases: evidence from the financial crisis

Purpose - – The purpose of this paper is to investigate the impact of insider trading on subsequent stock returns in the UK, with a specific focus on the impact of the global financial crisis of 2007-2008 on the relation between CEO and CFO stock purchases and returns. Design/methodology/approach - – The empirical analysis uses 10,230 purchases executed in 679 UK firms by 1,477 directors during the period from 2000 to 2010. Subsequent market-adjusted stock returns are regressed on a set of firm-specific accounting, market and corporate governance variables as well as the characteristics of CEOs and CFOs. Additionally, the analysis distinguishes between the opportunistic and routine trades. Findings - – The findings reveal that the position of the trading director and the nature of their trades are important in determining the impact on returns of insider trades. In particular, CEO purchases are on the whole more informative than CFO purchases and opportunistic purchases. The trades in the post-crisis period have a greater impact on subsequent stock returns. Research limitations/implications - – The empirical analysis is limited to the trades made by two executives. Future research should consider inside trades by all directors and distinguish between executive and non-executive directors. Also, a behavioral measure should be developed to test if the financial crisis affected the trading behavior of directors and whether directors use insider trading strategically to signal information to the market. Practical implications - – The impact of directors’ dealings on stock returns is not homogeneous. Financial analysts and investors should pay more attention to different types of trades and the identity of trading director. Originality/value - – This paper, to the authors’ knowledge, provides the first attempt that combines in the same framework the identity and personal attributes of trading executive directors, firm-level corporate governance features, the nature of purchase transactions and the trading period characteristics. Furthermore the empirical analysis is carried out during a period that also covers the recent global financial crisis period and its immediate aftermath.

Directors’ share dealings and corporate insolvencies: evidence from the UK

This paper investigates the relation between insider trading and the likelihood of insolvency with a specific focus on the directors’ sale and purchase transactions preceding insolvency. We use a unique data set on directors’ dealings in 474 non-financial UK firms, of which 117 filed for insolvency, over the period 2000–2010. We show that the directors of insolvent firms increase their purchase transactions significantly as the insolvency approaches. The results also reveal a significant relation between three different measures of insider trading activity and the likelihood of insolvency, which is observed to be positive only during the last six-month trading period. The relation is negative for the earlier trading periods. While the earlier purchase transactions appear to be motivated by superior information held by insiders, the purchase trades closer to the insolvency date are possibly initiated by directors’ motives to influence the markets perception of the firm in an attempt to avert or delay insolvency.

Securitisation and banking risk: what do we know so far?

Bank securitisation is deemed to have been a major contributing factor to the 2007/08 financial crises via fuelling credit growth accompanied by lower banksO credit standards. Yet, prior to the crisis a common view was that securitisation activity makes the financial system more stable as risk was more easily diversified, managed and allocated economy-wide. In this survey paper we review the extant literature to explore the so far generated knowledge on the impact of securitisation on banking risks. In particular, we examine the theoretical arguments and empirical studies on securitisation and banking risks before and after the global financial crisis of 2007/08. We identify the limitations of empirical studies and assess the comparability of findings. Theoretical literature univocally accentuate the undesirable consequences of securitisation, which may promote retention of riskier loans, undermine banksO screening and monitoring incentives and enhance banksO risk appetite. However, empirical evidence does not uniformly support the theoretical conclusions. If banks are securitisation active they lend more to risky borrowers, have less diversified portfolios and hold less capital, retain riskier loans and are aggressive in loan pricing. Others argue that securitisation reduces banks insolvency risk, increases profitability, provides liquidity and leads to greater supply of loans. Mortgage securitisation is an area where there is consistent evidence of bank risk taking via securitisation.
