The Impact of Enterprise Size on Employment Tribunal Incidence and Outcomes: Evidence from Britain

Employment Tribunals are the formal means of adjudicating disputes over individual employment rights in the UK. This article hypothesizes that, because small firms favour informality over formality, they are more likely (i) to experience employee claims than large firms; (ii) to be subject to different types of claims; (iii) to settle prior to reaching a formal Tribunal; and (iv) to lose at a Tribunal. Data from the 2003 Survey of Employment Tribunal Applications are used to examine these hypotheses. They are generally supported, although in relation to the third there was no size effect. Furthermore, our results show that firms that have procedures and follow them are more likely to win than those firms that do not have any procedures. Recognizing the benefits of informality, while also ensuring that small firms follow proper standards of procedural fairness, is a policy dilemma that has yet to be resolved.     

Benefits of diversifying investments into emerging markets with time-varying correlations: An Australian perspective

Australian investors can reduce their overall portfolio risk by diversifying into equities from other markets. Emerging markets have attracted significant interest because of their low correlations with Australian equity market returns; however, a number of studies have indicated that correlations between equity returns are increasing over time, so using unconditional estimates of correlations in a portfolio optimization model can result in the selection of a portfolio that may not be optimal.We use an Asymmetric Dynamic Conditional Correlation GARCH model to estimate time-varying correlations and include these correlation estimates in the portfolio optimization model. The assets used for portfolio construction comprise seven emerging market indices that are available to foreign investors. This study finds that, despite increasing correlations, there are still potential benefits for Australian investors who diversify into international emerging markets.     

How e-WOM recommendations influence product consideration and quality of choice: A motivation to process information perspective

A laboratory experiment examines the effects of electronic word-of-mouth (e-WOM) on consumer consideration and choice of an experience product. Specifically, we manipulated the number of consumer recommendations and the optimality of the recommended product in a realistic online shopping environment. The results indicate that e-WOM is likely to result in more time considering the recommended product. For consumers more motivated to process information, e-WOM recommendations lead to more time spent on the choice task overall. Further, consumers with less motivation to process information make suboptimal decisions based on e-WOM recommendations. Consumers with a high motivation to process information are willing to accept recommendations and switch from declared attribute preferences, but choose only optimal products.     

Size of Financing Need and the Choice between Asset Sales and Security Issuances

We study the effect of the size of financing need on a firm's choice between selling assets and issuing securities to finance its investments. The balance sheet effect predicts that a firm prefers to sell assets when the financing need is relatively small as there is less information asymmetry regarding the value of a (small) subset of its assets. When the financing need is large, a firm prefers issuing securities to selling assets. We find evidence supporting the prediction. Our findings remain unchanged when we employ measures of financing need that are relatively independent of the actual amount of financing raised.     

Value‐driven Internet shopping: The mental accounting theory perspective

When faced with competition and the ease with which customers can compare prices across sellers, Internet vendors often lower prices in a bid to increase sales. However, recent research reports that even price‐sensitive customers do not always purchase from Internet vendors offering the lowest prices. In contrast, value has been considered a key motivator of customer decision making in economics and marketing. However, little is known about the role and effect of value in Internet shopping. This study examines online customer purchase decision making from the value perspective based on mental accounting theory. This study also identifies monetary (perceived price) and non‐monetary (perceived risk, convenience, and pleasure) determinants of value. This study further explains how the individual determinants affect online purchase decision making directly and indirectly though value perception. The findings of this study offer Internet vendors practical suggestions for increasing online sales. This study, with its results, also helps advance knowledge of electronic commerce. © 2009 Wiley Periodicals, Inc.     

Log-concavity and monotonicity of hazard and reversed hazard functions of univariate and multivariate skew-normal distributions

This paper establishes the log-concavity property of several forms of univariate and multivariate skew-normal distributions. This property is then used to prove the monotonicity of the hazard as well as reversed hazard functions. The log-concavity and monotonicity of the hazard and reversed hazard functions of series and parallel systems of components is then discussed. The corresponding results for the multivariate normal distribution follow readily as special cases.     

Sustainable growth rate,optimal growth rate,and optimal payout ratio: A joint optimization approach

This study investigates the investment decision and dividend policy jointly from a non-steady state to a steady state. We extend ,  and  sustainable growth rate model and develop a dynamic model which jointly optimizes the growth rate and payout ratio. We optimize the firm value to obtain the optimal growth rate in terms of a logistic equation and find that the steady state growth rate can be used as the benchmark for the mean-reverting process of the optimal growth rate. We also investigate the specification error of the mean and variance of dividend per share when introducing the stochastic growth rate. Empirical results support the mean-reverting process of the growth rate and the importance of covariance between the profitability and the growth rate in determining dividend payouts. The intertemporal behavior of the covariance may shed some light on the fact of disappearing dividends over decades.     

What happens to social spending in IMF-supported programmes?

This article finds that education and health spending has risen during International Monetary Fund (IMF)-supported programmes at a faster pace than in developing countries as a whole. The analysis is based on the most comprehensive dataset assembled thus far for this purpose, with data covering 1985 to 2009 for 140 countries. Controlling for other determinants of education and health spending, including macroeconomic conditions, the results confirm that IMF-supported programmes have a positive and significant effect on social spending in low-income countries. Over a 5-year period with IMF-supported programmes, spending for education increases by about ¾ percentage point of Gross Domestic Product (GDP); and for health, by about 1 percentage point of GDP. IMF-supported programmes are also associated with increases in the share of government spending allocated to education and health.     

Volatility transmission between Islamic and conventional equity markets: evidence from causality-in-variance test

This study examines whether a volatility/risk transmission exists between the Dow Jones Islamic stock and three conventional stock markets for the United States, Europe and Asia during the pre- and the in- and post-2008 crisis periods. It also explores the volatility spillover dynamics between those markets and US Monetary policy, oil prices, global financial risk and uncertainty factors. The recently developed Hafner and Herwartz (2006)’s causality-in-variance test provides evidence of risk transfers between these seemingly different equity markets, indicating a contagion between them during the full sample and the subperiods. The volatility structure of these markets is dominated by short-run volatility in the first period and by high long-run volatility in the second period. The volatility impulse response analysis indicates a similar volatility transmission pattern although it is characterized by a more volatile and short-lived structure in the second period. It also appears that the Islamic equity market responds to shocks from the risk factors and not from the oil price and the US economic policy uncertainty index during both periods.     

Monotonicity of the (reversed) hazard rate of the (maximum) minimum in bivariate distributions

It is well known that in the case of independent random variables, the (reversed) hazard rate of the (maximum) minimum of two random variables is the sum of the individual (reversed) hazard rates and hence the onotonicity of the (reversed) hazard rate of the marginals is preserved by the monotonicity of the (reversed) hazard rate of the (maximum) minimum. However, for the bivariate distributions this property is not always preserved. In this paper, we study the monotonicity of the (reversed) hazard rate of the (maximum) minimum for two well known families of bivariate distributions viz the Farlie-Gumbel-Morgenstern (FGM) and Sarmanov family. In case of the FGM family, we obtain the (reversed) hazard rate of the (maximum) minimum and provide several examples in some of which the (reversed) hazard rate is monotonic and in others it is non-monotonic. In the case of Sarmanov family the (reversed) hazard rate of the (maximum) minimum may not be expressed in a compact form in general. We consider some examples to illustrate the procedureResearch of the second author is supported by a grant from Natural Sciences and Engineering Research Council and the research of the other two authors is partially supported by a travel grant from the Canadian American Center of the University of Maine
