Many organizations, such as banks, airlines, telecommunications companies, and police departments, routinely use queueing models to help manage and allocate resources in order to respond to demands in a timely and cost-efficient fashion. Though queueing analysis has been used in hospitals and other healthcare settings, its use in this sector is not widespread.
What do economics and history have to tell us about the ways euro zone countries are likely to resolve their problems of fiscal unsustainability and banking system insolvency? In answering that question, I am among the most pessimistic observers of the likely future of the euro and its membership. In my view, the euro zone's likely failure to avoid at least some departures, if not total collapse, reflects its poor initial institutional design.
Managing Change: Cases and Concepts, 3e by Todd Jick and Maury Peiperl is comprised of six modules that introduce common threads in the ensuing case studies and readings on organizational change. The materials in this edition — cases and readings — have been chosen and arranged to introduce change as an integrated process. Cases in the text represent a wide variety of change situations. Accompanying many cases are readings, likewise chosen to reflect a broad range of issues.
We propose a message-passing paradigm for resource allocation problems. This serves to connect ideas from the message-passing literature, which has primarily grown out of the communications, statistical physics, and artificial intelligence communities, with a problem central to operations research. This also provides a new framework for decentralized management that generalizes price-based systems by allowing incentives to vary across activities and consumption levels.
This paper shows that Chief Executive Officers (CEOs) meaningfully affect firm performance. Using variation in CEO exposure resulting from the numer of days a CEO is hospitalized, we provide estimates of the effect of CEOs on firm policies, holding firm and CEO matches constant. We have four main findings. First, CEOs have an economically and statistically significant effect on profitability, revenue, and investment outcomes. Firms whose CEOs are hospitalized underperform when their chief executives are sick but otherwise exhibit similar performance relative to other firms.
In this paper we study the determinants of business groups’ ownership structure using unique panel data on Korean chaebols. In particular, we attempt to understand how groups form over time. We find that chaebols grow vertically (that is, pyramidally) as the family uses well-established group firms (“central firms”) to set up and acquire firms that have low pledgeable income (e.g., low profitability) and high acquisition premia.
This research investigates the effects of regulatory focus on alternative search and consideration set formation in consumer decision making. Results from three experiments yield two primary findings. First, promotion‐focused consumers tend to search for alternatives at a more global level, whereas prevention‐focused consumers tend to search for alternatives at a more local level. Second, promotion‐focused consumers tend to have larger consideration sets than do prevention‐focused consumers.
