Predicting workload requirements for scheduled health care services, with an application to radiology departments.

A model is developed for predicting workload requirements for scheduled health care services. The model is then applied to an actual planning problem for a radiology department. The probability distribution of future workload is represented by the convolution of two families of random variables such that a compound Poisson process adequately describes workload requirements. The model developed herein can be applied to a wide assortment of capacity-expansion problems that are characterized by discrete demands (e.g. number of jobs) occurring in a given period of time, where the amount of time needed to complete each job is a continuous random variable.     

Proof of nonparticipation in a price fixing conspiracy

When a group of firms colludes on price, the industry price will rise even when there are some firms that do not participate in the conspiracy. If the government or private parties file antitrust suits, the noncolluders face the problem of establishing their innocence since their prices rise along with those of the colluders. We propose a simple output test. Under various models of oligopoly pricing—Bertrand, Cournot, and Stackelberg—we show that the colluders restrict their output while the noncolluders take advantage of the higher price by expanding their outputs. Thus, distinguishing between colluders and noncolluders involves simply observing the output behavior of the industry members.The authors appreciate the support of the Public Policy Research Center at the University of Florida.

Germany and the Euro-Zone Crisis: The European Reformation of the German Banking Crisis and the Future of the Euro

Analysis of the German response to the euro crisis has been framed around a narrative of the relationship between domestic sacrifice and hegemony and sustains an assumption that the German commitment to the euro is proven. Such analysis downplays the importance of the banking crisis in Germany in explaining the decision-making of the German government around the euro-zone debt crisis. Giving German interests in relation to the German banking crisis analytical weight can explain both the positions taken by the German government and their consequences for the underlying structural problems the euro-zone faces as a monetary union. Since the outcomes of German policy have advanced German interests, German handling of the euro-zone crisis cannot sustain a claim that Germany has demonstrated its commitment to the euro.     

Effects of dominance transitions on advice adherence in professional service conversations

For many professional services, advice adherence is a necessary condition for achieving service success for both customers and service providers. Despite their pivotal roles in value co-creation, typical conversational interactions often lead to low adherence. We propose that enabling a “dominance transition,” from provider dominance in the pre-advice stage to customer dominance in the post-advice stage, enhances advice adherence because it increases customers’ perceived common ground. Furthermore, providers’ consultation focus, customers’ prior knowledge, and customers’ perceived adherence effort moderate this process. Using mixed methods, including both empirical modeling and controlled and field experiments, we validate the proposed model in various contexts (healthcare, financial services, and fitness and wellness counseling). The findings establish several theoretical contributions and offer managerial implications for improving advice adherence by managing dominance transitions in conversational interactions more effectively through training service providers or even programming AI chatbots.

     

‘An Examination of the Ethical Commitment of Professional Accountants to Auditor Independence’

This research explores the relationship between work context and professional ethics. Specifically, we analyze through an online survey of professional accountants the degree to which changing work conditions have altered individual accountants’ commitment to the core professional value of auditor independence. We argue that certain changes in the condition of work have made some categories of accountants more susceptible to the logic of commercialism rather than the logic of professionalism. We find general support for this argument. We observe that accountants working outside of public accounting have a higher commitment to independence than do accountants working in the context of public accounting firms. We further observe that accountants in large international accounting firms (i.e. the “Big Four”) report lower commitment to auditor independence than do others in public accounting. And we observe that older accountants report stronger commitment to auditor independence. One finding, however, contradicts our general thesis. We find that commitment to one’s client does not necessarily result in a loss of commitment to the core professional value of independence. We conclude that changes in the context of work have contributed to the demise of ethics among professional accountants and suggest that further research be done to elaborate the relationship between client commitment and independence commitment.     

Does freezing a defined benefit pension plan affect firm risk?

This paper examines the impact of a defined benefit (DB) pension plan freeze on the sponsoring firm's risk and risk-taking activities. Using a sample of firms declaring a hard freeze on their DB plans between 2002 and 2007, we observe an increase in total risk (proxied by the standard deviation of EBITDA and asset beta), equity risk (standard deviation of returns), and credit risk following a DB-plan freeze. The increase in credit risk is reflected in a decline in credit ratings and an increase in bond yields for freezing firms. When we examine investment strategies, we observe a shift in investment from capital expenditures before the freeze to more-risky R&D projects after the freeze, and an increase in leverage. These strategies (increased focus on R&D and higher leverage) increase the operating and financial risk the firm faces. Overall, we observe an increase in risk-taking following DB plan freezes, consistent with theories that DB plans act as “inside debt” that aligns managers’ interests with bondholders’.     

Cooperation in environmental policy: a spatial approach

Inefficient competition in emissions taxes for foreign direct investment creates benefits from international cooperation. In the presence of cross-border pollution, proximate (neighboring) countries have greater incentives to cooperate than distant ones as illustrated by a model of tax competition for mobile capital. Spatial econometrics is used to estimate participation in 110 international environmental treaties by 139 countries over 20 years. Empirical evidence of increased cooperation among proximate countries is provided. Furthermore, strategic responses in treaty participation vary across country groups between OECD and non-OECD countries and are most evident in regional agreements.     

A Quantitative Exploration on the Determinants of (De-)Industrialisation: The case of Greece

The aim of this paper is to explore the main determinants of (de-) industrialisation, taking Greece as a case study. Industrialisation in postwar Greece measured in terms of manufacturing industry's share of output was not impressive. It reached its peak (20.2% of GDP) in the mid 1970s and, since then, it followed a declining path. Relevant theory relates the evolution of industry to macro and micro variables, stressing the role of structural change or 'trading up' within manufacturing. The regression results underline that the reasons behind the unimpressive Greek industrialisation performance, compared with advanced capitalist economies, are to be found in the low GDP per capita, the deep and long economic recession and the unfavourable manufacturing trade conditions. The preponderance of traditional, low technology, consumer goods sectors over high technology industries is also found to affect negatively the share of manufacturing, but its statistical significance is relatively small. The implications for industrialisation policies are that macro-variables should preferably be used, since micro-tools are not likely to be particularly effective.
