For the timely detection of business-cycle turning points we suggest to use mediumsized linear systems (subset VARs with automated zero restrictions) to forecast the relevant underlying variables, and to derive the probability of the turning point from the forecast density as the probability mass below (or above) a given threshold value. We show how this approach can be used in real time in the...

Addressing the call for a deeper understanding of ambidexterity at the individual level, we propose that managers’ networks are an important yet understudied factor in the ability to balance the trade-off between exploring for new business and exploiting existing business. Analyses of 1449 ties in the internal and external networks of 79 senior managers in a management consulting firm revealed ...

Objective. We examine the effects of interest community density on generalist interest organizations. A core element of population ecology theory is competitive exclusion, which suggests two hypotheses. First, through niche partitioning of the issue space among similar organizations and the comparative advantages of specialist organizations, generalists in heavily populated systems struggle to ...

This paper develops a methodology for estimating the parameters of dynamic opinion or expectation formation processes with social interactions. We study a simple stochastic framework of a collective process of opinion formation by a group of agents who face a binary decision problem. The aggregate dynamics of the individuals' decisions can be analyzed via the stochastic process governing the en...

The genesis of HomeAway, Inc. was startup by accretion – eight companies in the web-based vacation home rental market were acquired and merged. The technical solution during the merger and acquisition phase was to assimilate the software functionality of each of the eight companies into a one-size-fits-all application that could be configured with runtime settings to support the look-andfeel of...

The public perception of shared goods has changed substantially in the past few years. While co-owning properties has been widely accepted for a while (e.g., timeshares), the notion of sharing bikes, cars, or even rides on an on-demand basis is just now starting to gain widespread popularity. The emerging “sharing economy” is particularly interesting in the context of cities that struggle with ...

Background: Entrepreneurship plays an important role in the development of any country. Entrepreneurship is seen as the driving force behind economic development and the identification of opportunities and the use of resources, and entrepreneurs are those who, by recognizing opportunities, ensure success in manufacturing, business, and services. However, it should be noted that the criterion fo...

Mobile networks are increasingly becoming capacity limited such that more base stations and smaller cells or more spectrum are required to serve the subscribers’ increasing data usage. Among several challenges, the establishment of new base station sites becomes challenging and expensive. This study proposes and analyzes critical aspects of a business case where a mobile operator offloads its m...

From a technical point of view, Mobile WiMAX may offer an appropriate solution for delivering broadband wireless access. Two remaining questions, however, are whether the rollout of a WiMAX network is economically feasible or not, and how technical improvements like MIMO, beamforming and turbo-coding can influence the business case. In this paper different technical scenarios for a Mobile WiMAX...
