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.     

The Effect of Internal Control Certification Regulatory Changes on Real and Accrual-based Earnings Management

ABSTRACT

This study examines the effect of changes in internal control certification requirements (ICCR) on the earnings management choices of Australian firms in the period 2007–2015. The Australian setting is unique as the certification requirements change from voluntary in 2004–2007 to mandatory in 2008–2014, before being abolished in 2015. Consistent with the notion that real earnings management (REM) is less susceptible to detection, the results suggest that firms place greater reliance on REM than on accrual-based earnings management (ABEM) when having to comply with certification requirements. In particular, I find voluntary certifiers have lower REM and ABEM relative to first-time certifiers in the mandatory period between 2008 and 2014, and there is an increase in REM activities among first-time mandatory period certifiers. Moreover, firms that discontinue certification, after the abolition of the requirement in 2015, switch from REM to ABEM. This suggests that regulatory ICCR changes affect firms’ earnings management choices.     

Social Entrepreneurship: The Role of Institutions

A relatively small segment of business, known as social entrepreneurship (SE), is increasingly being acknowledged as an effective source of solutions for a variety of social problems. Because society tends to view “new” solutions as “the” solution, we are concerned that SE will soon be expected to provide answers to our most pressing social ills. In this paper we call into question the ability of SE, by itself, to provide solutions on a scope necessary to address large-scale social issues. SE cannot reasonably be expected to solve social problems on a large scale for a variety of reasons. The first we label the organizational legitimacy argument. This argument leads to our second argument, the isomorphism argument. We also advance three other claims, the moral, political, and structural arguments. After making our arguments, we explore ways in which SE, in concert with other social institutions, can effectively address social ills. We also present two examples of successful ventures in which SEs partnered with governments and other institutions.     

LIQUIDITY AND MATURITY EFFECTS AROUND NEWS RELEASES

We study the effects of liquidity and term-to-maturity following macroeconomic news announcements. To do this we select five instruments that differ in liquidity, or term-to-maturity, or both, and examine their response to the release of macroeconomic news. The results from this study suggest that variance on announcement days is higher in more liquid, longer term-to-maturity instruments. When instruments differ in both term-to-maturity and liquidity, term-to-maturity effects dominate. Tests for persistence in higher volatility in the five instruments following news releases show that most of the effects of the announcements seem to be well absorbed within fifteen minutes of the announcements. However, the evidence also suggests that the effects persist for longer periods in instruments that are more liquid. Term-to-maturity appears to have little or no effect in this instance.     

On the distribution of education and democracy

This paper examines the determinants of female autonomy within households in a developing country. In particular, we investigate the relative contributions of earned versus unearned income in enhancing women's autonomy and the role of employment outside of their husband's farm. In a simple theoretical model, it is demonstrated that earned income could be more important than unearned income in empowering women. Using data from rural Bangladesh, empirical estimations confirm this prediction and also reveal the surprising fact that it is not employment per se but employment outside their husbands' farms that contributes to women's autonomy. The data also point to the importance of choosing the correct threat point in theoretical analyses of female autonomy.     

Enabling the Original Intent: Catalysts for Social Entrepreneurship

As capitalist economies have shifted their primary focus from providing goods and services for all, to concentrating wealth at the top echelons of societies, social entrepreneurs have been one source of re-capturing the original intent of capitalism. Social entrepreneurs have combined the efficiency and effectiveness of business organizations with the social concerns of many non-profit and governmental agencies. As a result, social entrepreneurship is viewed as having significant potential for alleviating many of the social ills we now face. To accomplish this mission, however, will require expansion of social enterprises beyond their current footprints. We explore alternate methods of expansion, scaling and replication, and then examine potential catalysts, which can enable social entrepreneurs to attain their goals of social improvement. The catalysts we identify are effectual logic, enhanced legitimacy through appropriate reporting metrics, and information technology. We conclude with two brief case studies that exemplify how these catalysts are currently working to enhance the effectiveness of social start-ups.     

Endogenous Cartel Formation

This paper investigates the endogenous formation of cartels in a supergame framework in which cheating on the cartel agreement results in the ejection of only the defector from the cartel while collusion continue s amongst the non-cheating members. A more sophisticated notion of cartel stability than has been analysed hitherto is developed here, and it is shown that cartels are even less stable than they are generally believed to be. When firms produce heterogeneous goods and set prices, cartels comprising a small fraction of the industry's firms are shown to be viable. The emergence of two or more cartels within the same industry is seen not only to be a distinct possibility but also to be quite likely     

A theory of gender differences in parental altruism

Abstract.  We offer a theory of gender differences in parental altruism based on the asymmetry that female fertility is constrained but male fertility is relatively unconstrained. Modelling human preferences as having been shaped during the Pleistocene, we derive evolutionarily stable, co‐evolved male and female preferences for altruism towards one's children. We demonstrate that there would be gender differences in parental altruism that depend on the relative abundance or scarcity of resources and the importance and substitutability of parental inputs in promoting the survival of offspring. The results point to greater altruism in females, under plausible conditions. JEL Classification: D64, J16, P46
