Current trends in hospital mergers and acquisitions

Healthcare reform will impact hospital consolidation in three key areas: Payment rates will decrease, indirectly encouraging consolidation by forcing hospitals to find new ways to reduce costs and increase negotiating clout with suppliers and payers. The cost of doing business will increase as hospitals spend more on compliance, technology, and physician employment. The ACO model will encourage hospital network formation by rewarding integrated healthcare systems that can reduce costs and improve quality.     

The Influence of Mood on Subordinates’ Ability to Resist Coercive Pressure in Public Accounting

This study reports on an experiment conducted to assess the influence of different affective mood states on auditors’ ability to resist obedience pressure to commit or overlook unethical acts in six audit contexts. Obedience pressure from superiors to comply with unethical directives is of particular concern in public accounting, given the hierarchical structure of audit teams and the power imbalance in superior–subordinate relationships. One hundred and seventy audit seniors from two large international public accounting firms participated in an experiment. Three different moods were induced in participants through work‐related trigger events: one positive active mood state (arousal) and two negative passive mood states (fear and insignificance). These mood states were anticipated to influence auditors’ expressed willingness to comply with their superiors’ unethical directives as set forth in our ethical scenarios. Our results indicate that low levels of arousal and high levels of fear and insignificance influenced compliance intentions. Our results also indicate overall high levels of expressed willingness to comply with superiors’ unethical directives. Implications of our findings for understanding the antecedents of unethical conduct within the accounting profession and for future research are discussed.     

A COMPREHENSIVE EXAMINATION OF VOLUME EFFECTS AND SEASONALITY IN DAILY SECURITY RETURNS

In this study, an integrated model of return seasonality is developed and the hypothesis that seasonality is associated with changes in relative trading volume is examined. Return regularities associated with the turn of the month, the week of the month, and holiday closings are documented. Beyond these effects, neither the turn of the year nor the January effect is significant for large firms. Relative volume is shown to display calendar regularities similar to those in returns, and tests indicate a causal relationship flowing from volume to returns.
