The Expiration of IPO Share Lockups

We examine 1,948 share lockup agreements that prevent insiders from selling their shares in the period immediately after the IPO (typically 180 days). While lockups are in effect, there is little selling by insiders. When lockups expire, we find a permanent 40 percent increase in average trading volume, and a statistically prominent three-day abnormal return of −1.5 percent. The abnormal return and volume are much larger when the firm is financed by venture capital, and we find that venture capitalists sell more aggressively than executives and other shareholders. We find limited support for several hypotheses that may explain the abnormal return, but no complete explanation.     

Integrated performance management using information technology: a study of UK charities

This paper explores how UK charities use information technology (IT) to support integrated performance management (IPM). Based on six case studies of small and medium-sized charities (SMCs), it finds that SMCs see IT as important for IPM, but face significant barriers establishing effective IPM. The paper concludes that charities would benefit from a more strategic infrastructure approach to IT, integrating IT for data, information and knowledge.     

Does size matter? The state of the art in small business ethics

In this paper the exclusive focus on large firms in the field of business ethics is challenged. Some of the idiosyncrasies of small firms are explained, and links are made between these and potential ethical issues. A review of the existing literature on ethics in small firms demonstrates the lack of appropriate research, so that to date we can draw no firm conclusions in relation to ethics in the small firm. Recommendations are made as to the way forward for small firm business ethics research. Questions for investigation are suggested using micro, meso and macro perspectives. Much exploratory work needs to be done to lay the groundwork for this important area of social and commercial research in the future.     

Is Environmental Dumping Greater when Plants are Footloose?

We address concerns that globalisation gives national governments incentives to set weak environmental policies and that these incentives are particularly strong in industries where plants are footloose. Using a simple model of imperfect competition, we compare the environmental policies that would be set by non-cooperative governments for two different move structures—where governments set environmental policies after firms decide where to locate (market share game) and where governments set environmental policies before firms decide where to locate (location game). We show that the extent of environmental dumping in the market share game can be greater than in the location game.

Moral hazard among the sick and unemployed: evidence from a Swedish social insurance reform

This paper studies a specific type of moral hazard that arises in the interplay between two large public social insurance systems in Sweden, namely the sickness insurance (SI) and the unemployment insurance (UI). Moral hazard can arise from the structure of the benefit levels as for some unemployed persons benefits from the SI are higher than benefits from the UI. We use a reform of the SI system that came into force on 1 July 2003 to identify the effect of economic incentives arising from the different benefit levels. The purpose of the reform was to eliminate the difference in benefits between the two social insurance systems. Our results from a duration analysis show clearly that the higher the sickness benefits, the higher the probability of reporting sick.
