Do Criminal Sanctions Deter Insider Trading?

Many developed markets have taken what appears to be a tough stance on illegal insider trading through the use of criminal sanctions. Although criminal sanctions represent a much greater penalty than civil sanctions, the higher burden of proof required makes their enforceability weaker. This trade off between severity and enforceability makes the impact of criminal sanctions ambiguous. We empirically examine this issue by studying the deterrence of insider trading following the introduction of criminal sanctions in a developed market. Significant changes in sanction regimes are rare, especially when criminal sanctions are introduced without other changes. In February 2008, New Zealand introduced criminal sanctions for insider trading. This change of law offers a unique setting in which to examine the deterrence effect of criminalization. Using measures for the cost of trading, degree of information asymmetry, and probability of informed trading, we find that the enactment of this law led to a worsening in these measures. These findings suggest that the weaker enforceability of criminalization outweighs the associated increased severity of the penalties in New Zealand.     

Risk appetite,carry trade and exchange rates

Using exchange rate data from four different countries (time zones), we examine the relationship between the Yen exchange rate against major currencies (i.e. USD/JPY, EUR/JPY, GBP/JPY, AUD/JPY and NZD/JPY) and measures of risk appetite (i.e. the S&P500 index, Dow Jones Industrial Average index and the VIX index). Our results show that the equity indexes, especially the Dow Jones Industrial Average, play a more important role in the determination of the Yen cross rates than VIX. The popular carry-trade currencies, i.e. NZD/JPY, AUD/JPY and GBP/JPY, are more affected by the US equity market than USD/JPY and EUR/JPY. While the long-term relationships are consistent across the four different time zones, the short-term dynamics are different. We find that the response of NZD/JPY, AUD/JPY and GBP/JPY to changes in the US stock market is much greater in the New Zealand and Australian zones than in the UK or US. Although the short-term relationship between exchange rates and the equity index is quite strong, the error correction speed is very sluggish. We also find evidence of asymmetric adjustment in the response of exchange rates to changes in global risk aversion. Carry trade currencies tend to appreciate gradually when conditions are favorable but fall sharply when market risk increases.     

New Zealand mutual funds: measuring performance and persistence in performance

The present study investigates the performance of New Zealand mutual funds using a survivorship‐bias controlled sample of 143 funds for the period of 1990–2003. Our overall results suggest that New Zealand mutual funds have not been able to provide out‐performance. Alphas for equity funds, both domestic and international, are insignificantly different from zero, whereas balanced funds underperform significantly. There is no evidence of timing abilities by the fund managers. In the short term, significant evidence of return persistence for all funds is observed. This persistence, however, is driven by ‘icy hands’ rather than ‘hot hands’. Finally, we find the risk‐adjusted performance for equity funds to be positively related to fund size and expense ratio and negatively related to load charges.

Political crises and the stock market integration of emerging markets

This paper investigates the role of political crises in explaining the degree of stock market integration in emerging markets over the period 1991-2006. Using the International Crisis Behavior database, which contains detailed information on political crises around the world, and employing data on more than 15,500 firms, we assess whether political crises affect stock market integration in 19 emerging markets in South and East Asia, Latin America, and Central and Eastern Europe. We conclude that crises with certain characteristics generally reduce the level of stock market integration in these regions. In particular, the beginning of a political crisis, its severity, the involvement of the US in the conflict, and the number of parties involved in a crisis all have impacts on the level of stock market integration in these markets.     

Contemporaneous Spillover Effects between the U.S. and the U.K. Equity Markets

We use high frequency data and the “identification through heteroskedasticity” approach of Rigobon (2003) to capture the contemporaneous volatility spillover effects between the U.S. and U.K. equity markets. We demonstrate the relevance of taking into account the information present during simultaneous trading hours by comparing the results generated by our structural vector autoregression with those of a traditional reduced-form vector autoregression. Our findings clearly demonstrate that contemporaneous relations matter and that ignoring them leads to inappropriate conclusions regarding the magnitude and direction of volatility spillover.     

Fuzzy Control Chart A Better Alternative for Shewhart Average Chart

This paper through a real illustrative example and a power test shows that designing a fuzzy control chart for process average of a continuous (variable) quality characteristic with a warning line is a better alternative to Shewhart chart in many respects, like providing better neural view to inspectors, offering different strategic options for company to choose, detecting the desire shifts more quickly, and more sensibility to small shifts without any complexity augmentation to the chart.     

Engineering consultants' perceptions of corporate branding: A case study of an international engineering consultancy

The corporate branding literature on B2B markets has developed fairly rapidly over the past decade. However, empirical support on employees' perception of corporate branding is very limited, particularly with respect to employees who fall outside the marketing/branding function within their organizations. This paper explores engineering consultants' views - as an under-researched context - on the implications of corporate branding. Findings reveal engineers' views about the significance of personal brands, the implications of incorporation, the ways in which corporate branding is carried out in their organizations, and associations of technical proficiency with the corporate brand. From the findings, four hypotheses have been developed for future research.
