Herding behaviour and the declining value relevance of accounting information: evidence from an emerging stock market

This article sheds light on the underlying mechanisms behind the changes in the value relevance of accounting information in the Karachi Stock Exchange (KSE) during the 1999–2010 period. We find that neither changes in earnings quality nor the earnings lack of timeliness hypothesis can explain the decline in the value relevance of accounting information in the KSE. Based on the stylized facts associated with the growth of the KSE and the broader economics literature, we argue that the reduction in the explanatory power of accounting information vis-à-vis stock returns was caused by herding behaviour. Empirical estimates from state-space model of herding behaviour confirm the existence of herding, and we find that the value relevance of accounting information is significantly lower in periods characterized by herding behaviour. This article is also amongst the first attempts to empirically demonstrate that an expansionary monetary policy and increases in foreign portfolio investment lead to increased levels of herding.     

An evaluation of the red-light camera programme in the city of Dammam,the Kingdom of Saudi Arabia

This study evaluated the effectiveness of red-light cameras in Dammam, the Kingdom of Saudi Arabia. Two methods were used to assess changes in crash risk at the intersections at which the red-light camera programme had been operating. Geospatial analysis was used to visualize trends in road crash density over the geographical region of Dammam and a pre--post-camera crash analysis was undertaken. The distribution of injury crashes was greater than that of crashes which included property damage, the latter of which was concentrated around central Dammam. The five red-light cameras installed in 2012 were located outside areas of high-crash and injury density, and the total number of crashes reported in the three-month periods after installation was double that before the cameras were installed. This increase in the number of crashes also occurred at the five comparison sites (without red-light cameras), indicating a null effect. The findings from this study are contrary to previous evaluations of speed management programmes associated with red-light cameras. The study highlights the challenges in obtaining data for such research and illustrates that a reliance on overt, fixed camera's to manage speed is unlikely to deliver significant reductions in road trauma.     

TAX AND SAVINGS IMPLICATIONS OF THE CANADIAN REGISTERED RETIREMENT SAVINGS PLANS

This paper shows that the net effective tax rate on the Registered Retirement Savings Plans (RRSPs) in Canada has not been inflation non-neutral because of the combination of the non-neutrality of various sources of retirement income and the progressivity of the personal tax system. The paper also shows that although the RRSPs provide some tax arbitrage opportunities, these opportunities in Canada are limited due to the non-tax-deductibility of interest on mortgage and consumer credits. Finally, on theoretical grounds, the paper argues that the RRSPs may not have provided any incentives for personal savings in Canada.     

Is energy consumption effective to spur economic growth in Pakistan? New evidence from bounds test to level relationships and Granger causality tests

The present study investigates the relationship between energy (renewable and nonrenewable) consumption and economic growth using Cobb–Douglas production function in case of Pakistan over the period of 1972–2011. We have used the ARDL bounds testing and Gregory and Hansen (1990) structural break cointegration approaches for long run while stationarity properties of the variables have been tested applying Clemente-Montanes-Reyes (1998) structural break unit root test.Our results confirm cointegration between renewable energy consumption, nonrenewable energy consumption, economic growth, capital and labor in case of Pakistan. The findings show that both renewable and nonrenewable energy consumption add in economic growth. Capital and labor are also important determinants of economic growth. The VECM Granger causality analysis validates the existence of feedback hypotheses between renewable energy consumption and economic growth, nonrenewable energy consumption and economic growth, economic growth and capital.     

An exploratory study of organizational flexibility in Malaysia: a research note

This note reports on an exploratory study examining the relationships between rules on employee behaviour and on management discretion and other aspects of organizations in Malaysia. Using the data from thirty-five Malaysian organizations, the authors highlight the differences between the implications of the rules for the two groups and their relationships with company performance.     

The idiosyncratic risks of a Shariah compliant REIT investor

This paper investigates the impact of Shariah compliant investment principles on the idiosyncratic risks of a Shariah compliant REIT investor. The importance of idiosyncratic risks in explaining cross-sectional returns of a constructed Shariah compliant REIT investor’s portfolio is further examined in this paper. In all constructed portfolios examined, there is a positive and significant relationship between expected idiosyncratic volatility and expected REIT returns of the constructed Shariah compliant portfolio (GCC Shariah compliance standards). This result is consistent and persistent after robustness tests are carried out. As such, idiosyncratic risks are an important factor to consider in the pricing of Shariah compliant REIT stock returns. On further examination, the significant relationship as seen in the constructed Shariah compliant portfolio can be explained from the firm-specific risks of the residential REIT sector which is the most dominant sector during the period of investigation. The implications of these results also point to the importance of Shariah compliance standards and screening methods which is a significant feature associated with the understanding of the relationship of idiosyncratic risks on expected REIT returns of Shariah portfolios. Results show contrasting results between a less-restrictive and restrictive Shariah compliant portfolio. We find a significant relationship between expected returns and the idiosyncratic risks specifically in the restrictive Shariah compliant portfolio.     

The impact of increasing non-agricultural market access on EU demand for imported fish: implications for Lake Victoria chilled fillet exports

Import demand functions for origin-specific chilled fish filletsto the EU using a Rotterdam-type production model are estimated.Results are used to project the impact of the EU expanding marketaccess to non-African countries. The preference erosion argumentsuggests that the lower tariffs will erode the competitive positionof African countries; however, when the total impact of pricesis considered, expanding preferential access may result in increasedimports from African countries. If tariffs are reduced to zero,the total EU imports are projected to increase by 4.1 per centresulting in a 2.2 per cent increase in chilled fillet importsfrom Lake Victoria.     

A Cramér-type large deviation theorem for sums of functions of higher order non-overlapping spacings

Let U ₁, U ₂, . . . , U _n–1 be an ordered sample from a Uniform [0,1] distribution. The non-overlapping uniform spacings of order s are defined as \({G_{i}^{(s)} =U_{is} -U_{(i-1)s}, i=1,2,\ldots,N^\prime, G_{N^\prime+1}^{(s)} =1-U_{N^\prime s}}\) with notation U ₀ = 0, U _n = 1, where \({N^\prime=\left\lfloor n/s\right\rfloor}\) is the integer part of n/s. Let \({ N=\left\lceil n/s\right\rceil}\) be the smallest integer greater than or equal to n/s, f _m (u), m = 1, 2, . . . , N, be a sequence of real-valued Borel-measurable functions. In this article a Cramér type large deviation theorem for the statistic \({f_{1,n} (nG_{1}^{(s)})+\cdots+f_{N,n} (nG_{N}^{(s)} )}\) is proved.
