Why Has IPO Underpricing Changed Over Time

Abstract: In the 1980s, the average first-day return on initial public offerings (IPOs) was 7%. The average first-day return doubled to almost 15% during 1990-1998, before jumping to 65% during the internet bubble years of 1999-2000. Part of the increase can be attributed to changes in the risk composition of the companies going public and a realignment of incentives. We attribute much of the higher underpricing during the bubble period to a changing issuer objective function. We argue that in the later periods there was less focus on maximizing IPO proceeds due to both an increased emphasis on research coverage and allocations of hot IPOs to the personal brokerage accounts of issuing firm executives.

Predicting Participation and Production Outcomes Through a Two-Dimensional Model of Organizational Commitment

Abstract: In this study, we tested a two-dimensional model of organizational commitment and theoretically relevant outcomes based on the motivational distinction proposed by March and Simon (1958) between em...

Error and attack tolerance of complex networks

Abstract: Many complex systems, such as communication networks, display a surprising degree of robustness: while key components regularly malfunction, local failures rarely lead to the loss of the global information-carrying ability of the network. The stability of these complex systems is often attributed to the redundant wiring of the functional web defined by the systems' components. In this paper we demonstrate that error tolerance is not shared by all redundant systems, but it is displayed only by a class of inhomogeneously wired networks, called scale-free networks. We find that scale-free networks, describing a number of systems, such as the World Wide Web, Internet, social networks or a cell, display an unexpected degree of robustness, the ability of their nodes to communicate being unaffected by even unrealistically high failure rates. However, error tolerance comes at a high price: these networks are extremely vulnerable to attacks, i.e. to the selection and removal of a few nodes that play the most important role in assuring the network's connectivity.

Modern approaches to conceptualizing and measuring human life stress.

Abstract: The idea that adverse life circumstances and negative life events contribute to disorder and disease has long been held. Advances in conceptualizing and defining these conditions under the common label of life stress have led to progress in measuring both the environmental and individual response characteristics that may promote disorder and disease. In general, a substantial and growing research literature supports the basic premise that life stress plays an important role in the development of many psychological and physical problems. Recent research, too, strongly suggests that interest in life stress in relation to health and disease will accelerate over the coming years. Yet debates and controversies remain concerning how to best conceptualize and measure life stress, which presents distinctive challenges for advancing the field. The present review examines the major issues pertaining to these debates, controversies, and challenges, for they will be crucial to resolve if progress is to be made in und...
