The Asymmetry of the Price Impact of Block Trades and the Bid-Ask Spread. Evidence from the London Stock Exchange

In this paper we examine the price impact of block trades for FTSE 100 firms over the time period 1998-2004. Resembling previous research we find evidence of an asymmetric price impact between block purchases and sales. We suggest that bid-ask bias may be a new conjecture to the asymmetry in the differences in buyer and seller initiated trades.Block Trades, Bid-Ask Bias, Asymmetry, Market Microstructure

“Family” ownership, tunneling and earnings management: A review of the literature

In this review article, we bring together a number of aspects of family firms that are ubiquitous in a number of institutional contexts, often as part of larger business groups. We pay particular attention to the mechanisms by which families retain control over firms, and the incentives of the families in control to expropriate other stakeholders by way of tunnelling. We examine the role of earnings management in facilitating tunnelling, and evidence about the incidence of earnings management in family firms. Our review suggests that while the literature on these aspects of family control is rich, the contexts in which the empirical exercises are undertaken are relatively few, and hence there is considerable opportunity to expand it to other contexts, in particular in the form of cross-country comparisons of the relative impact of agency conflicts and institutions on these issues.family control, group affiliation, agency problem, tunnelling, earnings management

THE LONG RUN RELATIONSHIP BETWEEN STOCK PRICES AND GOODS PRICES: NEW EVIDENCE FROM PANEL COINTEGRATION

We examine the long run relationship between stock prices and goods prices to gauge whether stock market investment can hedge against inflation. Data from sixteen OECD countries over the period 1970-2006 are used. We account for different inflation regimes with the use of sub-sample regressions, whilst maintaining the power of tests in small sample sizes by combining time-series data across our sample countries in a panel unit root and panel cointegration econometric framework. The evidence supports a positive long-run relationship between goods prices and stock prices with the estimated goods price coefficient being in line with the generalized Fisher hypothesis.

Modeling The Non-Linear Behaviour of Inflation Deviations From The Target

This study tests for and models non-linearities in inflation deviations from the target in five OECD countries that adopted inflation targeting over the 1990s. Our tests reject the linearity hypothesis and we show that the exponential smooth transition autoregressive (ESTAR) model is capable of capturing the non-linear behavior ofinflation misalignments. The extent of inflation deviations from the target varies across the OECD countries, with countries that consistently undershoot the target having a rapid adjustment process, whereas countries that overshoot the target have a slower revision back to equilibrium.

The impact of transactions costs in the UK stock market: Evidence and implications

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.There has been an increasing interest in the finance literature regarding the impact of transactions costs on US equity markets. The US empirical evidence indicates that transactions costs influence both trading volume (Atkins and Dyl (1997)) and asset returns (Amihud and Mendelson (1986)). Additionally, the theoretical finance literature also indicates that transactions costs affect equilibrium asset returns (Fisher (1994)). In this thesis we assess the impact of transactions costs on the UK equity markets, from four aspects. Firstly, we provide empirical support to the hypothesis that transactions costs affect the "holding period" of an asset in the portfolio of an investor. Secondly, we provide robust results showing that transactions costs affect equilibrium asset returns. Thirdly, we explain the variability of transactions costs with the use of information asymmetry, proxied by the variance of analysts' forecasts, in the spirit of Kim and Verrecchia (1994, 2001). Finally, we find that stock price and trading volume reaction to changes in the FTSE 100 list can be explained by liquidity effects, as proxied by the bid-ask spread. We provide overwhelming evidence, suggesting that transactions costs are important in UK equity markets.Economics and Finance Department, Brunel Universit

Reference-dependent preferences in the public and private sectors: A nonlinear perspective

Although existing studies in the strategic management literature examine the importance of reference points in the context of managerial decisions vis-à-vis organizational performance, there is surprisingly little evidence on how reference earnings affect employees' wellbeing and behavior. The present study closes this gap by investigating adaptation dynamics towards reference earnings in the context of employees’ behavioral responses to social comparisons. We argue that a wedge between actual and aspiration-level earnings causes discontent that spurs employees into action to materialize their aspirations. The robustness of such action depends on the size of the wedge in a nonlinear fashion, a hypothesis supported by our findings. Nevertheless, heterogeneity in behavioral responses is evident across the public and private sectors and across gender and educational attainment. Such heterogeneity could be partially attributed to differences in public service motivation among public and private sector employees, to the different weights that employees place on pecuniary vs. non-pecuniary rewards, and whether reference earnings are likely to trigger behavioral responses through a 'jealousy' or through an 'ambition' channel. These findings have implications for the design of strategic human resource management policies to establish reward structures encouraging employees to adopt risk attitudes that are consistent with an overall business strategic plan.adaptation; reference earnings; comparison income; reference-dependent preferences; ESTAR models
