Security needs of organizations are becoming more and more sophisticated nowadays. Most general-purpose operating systems (GPOS) provide access control policies to meet these needs. There are cases when the traditionally deployed Discretionary Access Control (DAC) rules are not sufficient: they tend to quickly become unmanageable in the case of large installations, and also are not enough for c...

The Effects of Disclosure Regulation on Innovative Firms: Private Values* by Jos Jansen Firms in an R&D race actively manage rivals’ beliefs by disclosing and concealing information on their cost of investment. The firms’ disclosure strategies affect their incentives to invest in R&D, and to acquire information. We compare equilibria under voluntary disclosure with those under mandatory disclos...

Organizational investments in such complex information systems as customer relationship management (CRM) systems have reached a record high. Unfortunately, underutilization of these sophisticated technologies hinders organizations from realizing the promised returns on investment. This study tackles this issue from the perspective of intention to explore, which refers to individual intentions t...

Using a Zero-Inflated Poisson (ZIP) model, we examine the effects of nonemployee director ownership and director plan adoption on the firms’ acquisition activity. We hypothesize that the firms’ acquisition activity increases with directors’ ownership as the directors’ incentives become more aligned with those of the shareholders, and they become less risk-averse. But at higher levels of ownersh...

Host compromise is a serious computer security problem today. To better protect hosts, several Mandatory Access Control systems, such as Security Enhanced Linux (SELinux) and AppArmor, have been introduced. In this paper we propose an approach to analyze and compare the quality of protection offered by these different MAC systems. We introduce the notion of vulnerability surfaces under attack s...

When the median voter's preference sets the level of local public goods, some voters are left unsatisfied. Is there an institution by which subsets of voters can resolve the collective action problem and increase the local provision of public goods? If so, what are the consequences? In response to problems such as crime and vandalism, neighborhood property owners have established Business Impro...

Abstract This paper examines whether and how inside ownership mediates the relation between disclosure quality and the cost of capital. Both ownership and more transparent reporting have the potential to align incentives between managers and investors thereby reducing systematic risk. Employing a large global sample across 35 countries over the 1990 to 2004 period, we show that countrylevel dis...

In this paper we examine the behavior of a firm that produces a product with a privatelyobserved safety attribute; that is, consumers cannot observe directly the product’s safety. The firm may, at a cost, disclose its safety prior to sale; alternatively, if a firm does not disclose its safety then consumers can attempt to infer its safety from the price charged. The liability system is importan...

Mandatory quality disclosure is pervasive across several industries and often includes a period over which the quality of new entrants is unreported. This provides the opportunity for forward-looking firms to adjust product characteristics in advance of disclosure. Using comprehensive data on Medicare Advantage from 2007-2014, I first demonstrate empirically that there exists a consumer respons...
