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

On the composition of government spending, optimal fiscal policy, and endogenous growth: Theory and evidence

In an endogenous growth model with two public services with differing productivities, this paper analytically characterises optimal fiscal policy for a decentralised economy, whereby the optimal values of the growth rate, tax rate and expenditure shares on the two public goods are linked directly to their productivity parameters. Using panel data for 15 developing countries over 28 years, we show using GMM techniques, that current (capital) spending has positive (negative) and significant effects on the growth rate, contrary to commonly held views. Our theoretical results extend, and our empirical results modify those obtained by Devarajan et al. (1996)

Liquidity effects due to information costs from changes

In this paper we examine effect on the returns of firms that have been included to and deleted from the FTSE 100 over the time period of 1984-2001. Like the S&P 500 listing studies, we find that the price and trading volume of newly listed (deleted) firms increases (decreases). The evidence is consistent with the information cost/liquidity explanation. This is because investors hold stocks with more (less) available information, consequently implying that they have lower (higher) trading costs. This explains the increase (decrease) in the stock price and trading volume of newly listed (deleted) stocks to (from) the FTSE 100 List

The impact of government expenditure on growth: Empirical evidence from a heterogeneous panel

This paper investigates the impact of government expenditure on growth, in a heterogeneous panel for 15 developing countries. Using GMM techniques, we show that countries with substantial government expenditure have strong growth effects, which vary considerably across the nations

What happens around earning announcements? An investigation of information asymmetry and trading activity in the Saudi market

This paper examines stock returns and trading activities around earnings announcements for listed companies in the Saudi stock market (SSM). Specifically, we examine the levels of stock liquidity, trading activity, volatility, bid-ask spread, asymmetric information and investor trading behaviour around earnings announcements for all firms in the market for the period 2002-2009. Abnormal price and volume reactions around earnings announcements suggest that these announcements produce highly informative contents. The magnitude of the cumulative abnormal returns around earnings announcement is induced by trading activity in the two weeks before the release date. We also show evidence of an increased adverse selection cost around earnings announcement, which is then gradually reduced in the post-announcement period, indicating that earnings announcements reduce uncertainty in the market. We also examine trading behaviour among small and large investors in the market through constructing order imbalance measures. In general, large investors are more sophisticated and show higher informed trading before earnings announcements whereas smaller investors show stronger reaction to news. Moreover, small investors show a buying pattern which is consistent with times-series based earnings surprise. They are net-buyers for good news and net-sellers for bad news portfolios

Non-normality and recursive unit root test for PPP: Solving the PPP puzzle?

In this paper we carry out unit root tests on real exchange rates recursively as in Caporale et al (2003), but, following Arghyrou and Gregoriou (2007), we adjust the residuals for non-normality using a wild bootstrap method. The results are striking: the correction for non-normality dramatically increases the rejection percentages of the unit root null, and attenuates the erratic behaviour of the t-statistic, thus providing strong evidence in favour of PPP, and suggesting that such a correction might at least go some way towards solving the “PPP puzzle”

GMM and present value test of the C-CAPM under transactions costs: Evidence from the UK stock market

In this paper we test for the inclusion of the bid-ask spread in the consumption CAPM, in the UK stock market over the time period of 1980-2000. Two econometric models are used; first, Fisher’s (1994) asset pricing model is estimated by GMM, and secondly, the VAR approach proposed by Campbell and Shiller is extended to include the bid-ask spread. Overall the statistical tests are unable to reject the bid-ask spread as an independent explanatory variable in the C-CAPM. This leads to the conclusion that transactions costs should be included in asset pricing models

Can market frictions really explain the price impact asymmetry of block trades? Evidence from the Saudi stock market

We empirically examine the price impact of block trades, in the Saudi Stock Market over the time period of 2005-2008. Using a unique dataset of intraday data consisting of 2.3 million block buys and 1.9 million block sales, we find an asymmetry in the price impact of block purchases and sales. The asymmetry persists even when we account for the bidask bias in block trades, which is contrary to the previous literature. Overall, our findings suggest that in an emerging market where institutional trading is relatively scarce, market microstructure cannot explain the asymmetry in the price impact of large trades

Is democracy beneficial for growth in countries with low ethnic diversity?

We study the impact of democracy on economic growth for a panel of the most and least ethnically diverse nations as documented by Easterly and Levine (1997). Using a GMM system to capture endogeneity and simultaneity, we find that democracy exerts a direct positive impact on growth, in addition to ameliorating the adverse effects of ethnic diversity on growth, unlike some of the results of the previous empirical literature

“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.http://deepblue.lib.umich.edu/bitstream/2027.42/64422/1/wp954.pd
