On-line/Off-line: Joint Negotiation Teaching in Montreal and Vienna

E-business systems, the most recent generation of information systems, can be effectively used in teaching. One such system was developed and used in a collaborative project that involved teaching of negotiation theory and practice to students from Austria and Canada. The system provides customized course materials and a platform to conduct various e-negotiation activities. The design allows combining e-learning technologies designed to support students in their independent and individual learning with conventional face-to-face training. Our experience indicates that professional negotiation training accompanied by e-learning, and tools to support decision-making and negotiation can foster students' appreciation of the technology as well as demonstrate its limitations. The combination of technology-intensive and conventional resources contributed to students' awareness of social influences on negotiations, importance of communication, and focussed their attention on the problem and its solution. Deeper customization of the course content and delivery may further contribute to effective learning and acquiring of both communication and analytical skills.     

The growing dependence of Britain on trade during the Industrial Revolution

Many previous studies of the role of trade during the British Industrial Revolution have found little or no role for trade in explaining British living standards or growth rates. We construct a three-region model of the world in which Britain trades with North America and the Rest of the World, and calibrate the model to data from the 1760s and 1850s. We find that while trade had only a small impact on British welfare in the 1760s, it had a very large impact in the 1850s. This contrast is robust to a large range of parameter perturbations. Biased technological change and population growth were key in explaining Britain's growing dependence on trade during the Industrial Revolution.     

Primary vs secondary prophylaxis with pegfilgrastim for the reduction of febrile neutropenia risk in patients receiving chemotherapy for non-Hodgkin’s lymphoma: cost-effectiveness analyses

Objective:

Evaluate the cost-effectiveness of primary vs secondary prophylaxis (PP vs SP) with pegfilgrastim to reduce the risk of febrile neutropenia (FN) in Non-Hodgkin’s Lymphoma (NHL) patients receiving myelosuppressive chemotherapy from a US payer perspective.

Methods:

A Markov model was used to compare PP vs SP with pegfilgrastim in a cohort of patients receiving six cycles of cyclophosphamide, vincristine, doxorubicin, and prednisone (CHOP) or CHOP plus rituximab (CHOP-R) chemotherapy. Model inputs, including efficacy of pegfilgrastim in reducing risk of FN and costs, were estimated from publicly available sources and peer-reviewed publications. Incremental cost-effectiveness was evaluated in terms of net cost per life-year saved (LYS), per quality-adjusted life-year (QALY) gained, and per FN event avoided over a lifetime horizon. Deterministic and probabilistic analyses were performed to assess sensitivity and robustness of results.

Results:

Lifetime costs for PP were $5000 greater than for SP; however, PP was associated with fewer FN events and more LYs and QALYs gained vs SP. Incremental cost-effectiveness ratios (ICERs) for PP vs SP for CHOP were $13,400 per FN event avoided, $29,500 per QALY gained, and $25,800 per LYS. CHOP-R results were similar ($15,000 per FN event avoided, $33,000 per QALY gained, and $28,900 per LYS). Results were most sensitive to baseline FN risk, cost per FN episode, and odds ratio for reduced relative dose intensity due to prior FN event. PP was cost-effective vs SP in 85% of simulations at a $50,000 per QALY threshold.

Limitations:

In the absence of NHL-specific data, estimates for pegfilgrastim efficacy and relative risk reduction of FN were based on available data for neoadjuvant TAC in patients with breast cancer. Baseline risks of FN for CHOP and CHOP-R were assumed to be equivalent.

Conclusions:

PP with pegfilgrastim is cost-effective compared to SP with pegfilgrastim in NHL patients receiving CHOP or CHOP-R.     

Optimal fertility along the life cycle

We explore the optimal fertility timing in a four-period OLG economy with physical capital, whose specificity is to include not one, but two reproduction periods. It is shown that, for a given total fertility rate, the economy exhibits quite different dynamics, depending on the timing of births. If all births take place in the late reproduction period, there exists no stable stationary equilibrium and the economy exhibits cyclical dynamics due to labor growth fluctuations. We characterize the long-run social optimum and show that optimal consumptions and capital depend on the optimal cohort growth factor, so that there is no one-to-one substitutability between early and late fertility. We also extend Samuelson’s Serendipity Theorem to our economy and study the robustness of our results to: (1) endogenizing fertility timing, (2) assuming rational anticipations about factor prices, (3) adding a third reproduction period.     

On the County-Level Credit Outcome Beta

In their pioneering work, Musto and Souleles (Journal of Monetary Economics 53(1):59–84, 2006) apply portfolio theory to consumer lending. This paper extends their work by analyzing three county-level credit outcome betas. We use the probability of default calibrated from the credit score, the actual default rate, and the actual bankruptcy rate to compute ‘score’, ‘default’, and ‘bankruptcy’ betas for each U.S. county. The correlation between default and bankruptcy betas is quite low. Counties in states in which a borrower has a right to take action against aggressive collection practices tend to have higher default betas but lower bankruptcy betas. These findings suggest the possibility of an ‘informal bankruptcy’ option for consumers. The effects of county score, default, and bankruptcy betas on the county average revolving credit line per borrower are negative. For small lenders that do not have access to the detailed historical credit files on individual consumers, the county-level beta approach of this paper might be helpful for diversifying portfolios geographically and managing risk on existing accounts.     

Decision neuroscience and consumer decision making

This article proposes that neuroscience can shape future theory and models in consumer decision making and suggests ways that neuroscience methods can be used in decision-making research. The article argues that neuroscience facilitates better theory development and empirical testing by considering the physiological context and the role of constructs such as hunger, stress, and social influence on consumer choice and preferences. Neuroscience can also provide new explanations for different sources of heterogeneity within and across populations, suggest novel hypotheses with respect to choices and underlying mechanisms that accord with an understanding of biology, and allow for the use of neural data to make better predictions about consumer behavior. The article suggests that despite some challenges associated with incorporating neuroscience into research on consumer decision processes, the use of neuroscience paradigms will produce a deeper understanding of decision making that can lead to the development of more effective decision aids and interventions.     

Market Delineation under the Merger Guidelines: Monopoly Cases and Alternative Approaches

Despite the well-known Cellophane fallacy, the Merger Guidelines' market-delineation paradigm, which examines the effects of price increases above the prevailing level, has substantial utility in many monopoly cases. For monopoly cases in which the Guidelines' approach is not appropriate due to the Cellophane fallacy, no modification of that approach appears to solve the problem is a useful way. More direct methods for assessing monopoly power are likely to be preferable to structural analysis in many monopoly and merger cases.     

Control-based channel governance and relative dependence

Control and governance theories recognize that exchange partners are subject to two general forms of control, the unilateral authority of one firm and bilateral expectations extending from their social bond. In this way, a supplier both exerts unilateral, authority-based controls and is subject to socially-based, bilateral controls as it attempts to manage its brand successfully through reseller channels. Such control is being challenged by suppliers’ growing relative dependence on increasingly dominant resellers in many industries. Yet the impact of supplier relative dependence on the efficacy of control-based governance in the supplier’s channel is not well understood. To address this gap, we specify and test a control model moderated by relative dependence involving the conceptualization and measurement of governance at the level of specific control processes: incenting, monitoring, and enforcing. Our empirical findings show relative dependence undercuts the effectiveness of certain unilateral and bilateral control processes while enhancing the effectiveness of others, largely supporting our dual suppositions that each control process operates through a specialized behavioral mechanism and that these underlying mechanisms are differentially impacted by relative dependence. We offer implications of these findings for managers and identify our contributions to channel theory and research.
