This paper introduces a class of state dependent jump (SDJ) models in which the arrival intensity and jump sizes depend on a given set of state variables, including lagged jumps. With this model, we investigate the structure of jumps to U.S. equity indices, concentrating on the predictability of jumps times if found for all of the indices considered: Standard and Poor's 500 and Mid-Cap, the Russell 1000, 2000, and 3000 indices, the Wilshire 5000 and the Nasdaq 100 (NDX).

Marketers all over the world agree that the Internet will have a major impact on the way firms do business. What changes will exactly occur, however, is hard to predict as the Internet is in a phase of rapid growth and constant change. Patterns are difficult to isolate, especially since despite its explosive growth, today, the Net is still in its infancy, only being available to a small proportion of people. In spite of this general lack of reliable patterns, one consensus among managers seems to be that the Internet is likely to intensify price competition.

This article analyzes how Knowledge Management (KM) is likely to affect competition in the management consulting industry. KM represents a fundamental and qualitative change in this industry's basic production technology. Because management consultants acquire information directly from their customers, for these firms, KM technology exhibits increasing returns to scale. As such, although KM clearly represents an opportunity for some consultants to build a sustainable competitive advantage, it is likely to lead to a shake-out.

This article proposes a method that overcomes a number of problems associated with new product diffusion models noted in the marketing literature. We illustrate the methodology in the context of better understanding global variances in new product adoption. Building on existing diffusion models and sample matching principles from international consumer research, we suggest a "staged estimation procedure." The procedure provides both sensible and robust estimates and remains usable even if the diffusion process is in its earliest stage in most or all countries.

In The Boundaryless Organization, a world-class team of management experts showed how leading companies were becoming more flexible, innovative, and competitive by breaking the barriers that limit the free flow of resources and information. Now, The Boundaryless Organization Field Guide gives executives, managers, and HR professionals the guidance and resources they need to make their own organizations boundaryless. This hands-on kit includes materials based on the acclaimed WorkOut process initiated at General Electric.

This paper presents an applied methodology to assist managers in strategically setting prices and allocating resources over the product, brand, or adoption (diffusion) life cycle. While substantial theoretical work has been achieved in this area in the management science and operations research disciplines, approaches which can be implemented as managerial tools are generally lacking.

Selling information that is later used in decision making constitutes an increasingly important business in modem economies (Jensen 1991). Information is sold under a large variety of forms: industry reports, consulting services, database access, and/or professional opinions given by medical, engineering, accounting/ financial, and legal professionals, among others.
