Planning a sustainable reverse logistics system: Balancing costs with environmental and social concerns

The present work aims to support tactical and operational planning decisions of reverse logistics systems while considering economic, environmental and social objectives. In the literature, when addressing such systems economic aspects have been often used, while environmental concerns have emerged only recently. The social component is the one less studied and rarely the combination of the three concerns has been analyzed. This work considers the three objectives and was motivated by the challenge of supporting decision makers when managing a real case study of a recyclable waste collection system, where strategic decisions on the number and location of depots, vehicles and containers were taken beforehand. Tactical and operational decisions are studied involving the establishment of service areas for each depot and the definition and scheduling of collection routes for each vehicle. Such decisions should represent a compromise solution between the three objectives translating a sustainable reverse logistics plan. The problem is modeled as a multi-objective, multi-depot periodic vehicle routing problem with inter-depot routes. A mathematical formulation and a solution approach are proposed. An approximation to the Pareto front is obtained for the case study and the trade-offs between the objectives are discussed. A balanced solution is proposed.     

Forecasting political decisions and their impact on business

The economic and technical background against which business enterprises operate is largely determined by political decisions. These decisions influence the market, constrain freedom of action, and create new investment openings. It is therefore important for business organizations to attempt to evaluate possible political changes in their strategic planning in order to test the realism of their economic and/or technical planning.     

The Effect of Expected Income on Individual Migration Decisions

This paper develops a tractable econometric model of optimal migration, focusing on expected income as the main economic influence on migration. The model improves on previous work in two respects: it covers optimal sequences of location decisions (rather than a single once‐for‐all choice) and it allows for many alternative location choices. The model is estimated using panel data from the National Longitudinal Survey of Youth on white males with a high‐school education. Our main conclusion is that interstate migration decisions are influenced to a substantial extent by income prospects. The results suggest that the link between income and migration decisions is driven both by geographic differences in mean wages and by a tendency to move in search of a better locational match when the income realization in the current location is unfavorable.     

Economic development and ecological equilibrium—A target conflict in modern industrial enterprises

The increased utilization of natural resources burdens the economic systems of the whole world. In order to stop, or at any rate to mitigate, the consequences of this development anti-pollution measures are necessary. Planned and realized standards are to a growing extent important for the formulation of strategies which influence the product concepts and production procedures as well as locational decisions of companies. The conflict between economic development and ecological balance can only be solved if the social groups reach a consensus on the priorities of the tasks to be accomplished.     

Facility location decisions with environmental considerations: a case study from the petrochemical industry

The recently growing concerns of customers and governments about environmental protection and greenhouse gas reduction have forced companies to integrate the topic of environmental sustainability into their decision making. Facility location decisions are of special relevance in this respect because of their strategic nature. Furthermore, many different trade-offs must be considered, for example between operational costs and customer service. But as soon as environmental issues are concerned, other critical issues must be considered as well. Based on a case study from the petrochemical industry, this paper extends two basic facility location models and shows the impact of distribution network-design decisions on the economic and environmental performance of the company. The results show a trade-off between total (distribution) costs and transport carbon emissions.     

SIMULATING FOOD SHOPPERS' ECONOMIC LOSSES AS A RESULT OF SUPERMARKET UNAVAILABILITY*

This study illustrates a methodology as a first step toward the development of a benefit/cost model for the evaluation of the Federal Trade Commission regulation of the unavailability of advertised specials in food stores. A Monte Carlo simulation was used to estimate economic losses to shoppers from unavailable advertised specials. Product unavailability in the model occurred as a result of alternative managerial decisions about purchase-order quantities for advertised specials and shelf-stocking policies combined with probabilistic purchase decisions by customers. The model generated probabilistic individual customer and management behavioral responses to unavailability during a one-year time period. As a result, the derived economic losses to customers from unavailability were based on alternative assumptions about managerial behavior in conjunction with empirically derived shopper responses to advertised specials. This study thus provides some idea of the amount of damages being caused by the excessive unavailability of advertised specials. Aggregate customer losses were found to vary primarily with respect to management's purchase-order quantity of advertised specials.     

Competitive procurement strategies: Building strength and reducing vulnerability

Current economic conditions and resource constraints call into question many of the implicit assumptions to which traditional strategic planning models subscribe. An attempt is made to bridge the gap between product/market decisions and concerns for present and future resource availability. The author develops the notion of strategic procurement planning as an approach to make more salient the potential competitive ramifications of procurement related decisions and for better integrating purchasing into the corporate planning process.     

Individuelle Freiheit als Grundlage normativer Ökonomik

The economic approach to CSR has been increasingly criticized as being too narrow to provide a basis for ethical judgments. However, economic theory makes an implicit but fundamental ethical judgment as it emphasizes individual freedom, premising that everyone should be free to make their decisions in the marketplace. I interpret this ethical judgment explicitly and derive three implications, which allow assessing the legitimacy of corporate action in a globalized world. More specifically, I argue that contracts must rely on the voluntary and informed consent of all people concerned to be legitimate. Companies have the responsibility to ensure that these criteria are met in their contracts.

Economic Models for Single Sample Acceptance Sampling Plans,No Inspection,and 100 Percent Inspection

Once a process is stabilized using control charts, it is necessary to determine whether this process is capable of producing die desired quality, as determined by the specifications, without the use of some additional inspection procedure such as 100 percent inspection or acceptance sampling. One common method of making this determination is the use of process capability ratios. However, this approach may lead to erroneous decisions due to the omission of economic information. This paper attempts to remedy this situation by developing economic models to examine the profitability of different inspection policies. These models employ the quadratic loss function to represent the economic cost of quality from external failures, which is commonly omitted or overlooked. Moreover, assuming a normal distribution for the quality characteristic allows the use of simplified formulas that are provided. Thus the calculations can be made using standard normal tables and a calculator. Additionally, these economic models may be used to determine if additional inspection procedures should be reinstated if the quality of the process was to decline, to make capital budgeting decisions involving new equipment that produces parts of a higher quality, and to determine the preferred 100 percent inspection plan or acceptance sampling plan.     

Following the Thread: Industry Cluster Theory,the New England Cotton Textiles Industry,and Implications for Future Supply Chain Research

The purpose of this paper is to introduce supply chain management researchers to industry cluster theory within the context of supply chain management decisions. Industry cluster theory emphasizes the explicit and implicit benefits that accrue to various economic players due to geographic proximity. As such, it provides a contrasting view to the current pressure on supply chains to seek out the “best” partners, regardless of location. We review the theory behind industry clusters, and illustrate it using the example of the New England cotton textile industry. Incorporating these concepts into future research has the potential to improve our understanding of how decisions regarding supply chain location and sourcing decisions are currently made, and what role location‐based benefits should play in these decisions.     

When does part-time employment allow managers with family responsibilities to stay on the career track? A vignette study among German managers

The present study examines the specific conditions under which part-time (PT) arrangements in managerial jobs allow parents with childcare responsibilities to stay on the career track. By integrating economic signaling theory and gender role congruity theory, a vignette study among German managers revealed that substantial PT hours, flexible working schedules, and flexible childcare arrangements positively influence decision makers’ personal promotion decisions. Further, we found a significant fatherhood bias with male PT managers receiving less favorable promotion decisions than female PT managers. The study further reveals that decision makers’ evaluations of managers’ levels of advancement motivation mediate several significant relationships. The paper discusses practical impactions and future research directions.     

An Equilibrium Model of Health Insurance Provision and Wage Determination

We investigate the effect of employer‐provided health insurance on job mobility rates and economic welfare using a search, matching, and bargaining framework. In our model, health insurance coverage decisions are made in a cooperative manner that recognizes the productivity effects of health insurance as well as its nonpecuniary value to the employee. The resulting equilibrium is one in which not all employment matches are covered by health insurance, wages at jobs providing health insurance are larger (in a stochastic sense) than those at jobs without health insurance, and workers at jobs with health insurance are less likely to leave those jobs, even after conditioning on the wage rate. We estimate the model using the 1996 panel of the Survey of Income and Program Participation, and find that the employer‐provided health insurance system does not lead to any serious inefficiencies in mobility decisions.     

Risk Preferences in Strategic Wildfire Decision Making: A Choice Experiment with U.S. Wildfire Managers

Federal policy has embraced risa management as an appropriate paradigm for wildfire management. Economic theory suggests that over repeated wildfire events, potential economic costs and risas of ecological damage are optimally balanced when management decisions are free from biases, risa aversion, and risa seeking. Of primary concern in this article is how managers respond to wildfire risa, including the potential effect of wildfires (on ecological values, structures, and safety) and the likelihood of different fire outcomes. We use responses to a choice experiment questionnaire of U.S. federal wildfire managers to measure attitudes toward several components of wildfire risa and to test whether observed risa attitudes are consistent with the efficient allocation of wildfire suppression resources. Our results indicate that fire managers’ decisions are consistent with nonexpected utility theories of decisions under risa. Managers may overallocate firefighting resources when the likelihood or potential magnitude of damage from fires is low, and sensitivity to changes in the probability of fire outcomes depends on whether probabilities are close to one or zero and the magnitude of the potential harm.

An economic evaluation model of product mix flexibility

This paper develops a product mix flexibility model comprising labor flexibility, machine flexibility, routing flexibility, and information technology, with the product mix flexibility measured by an economic index. Outputs from the model can be useful in making suitable production decisions to produce multiple products in an uncertain environment. Example solutions are given. How the product mix flexibility is affected by flexibility factors is discussed, and the results show that the bottleneck plays the most important role. This paper can help economic evaluation when product mix flexibility and the factors affecting flexibility are to be improved. It can also assist in making enterprise flexibility promotion decisions.     

The economic evaluation of time: Organizational causes and individual consequences

People acquire ways of thinking about time partly in and from work organizations, where the control and measurement of time use is a prominent feature of modern management—an inevitable consequence of employees selling their time for money. In this paper, we theorize about the role organizational practices play in promoting an economic evaluation of time and time use—where time is thought of primarily in monetary terms and viewed as a scarce resource that should be used as efficiently as possible. While people usually make decisions about time and money differently, we argue that management practices that make the connection between time and money salient can heighten the economic evaluation of time. We consider both the organizational causes of economic evaluation as well as its personal and societal consequences.     

Transforming communication,transforming business: Stimulating value negotiation for more responsive and responsible workplaces

If commercial corporations are to stay economically viable and the general society is to stay healthy, corporate decisions must be even more responsive to rapidly changing environments and stakeholder needs and responsible in increasingly complex and interdependent social contexts. The dominant economic conception of corporations and the accompanying emphasis on profitability, value-neutral rationality, and managerial control is increasingly problematic. Public values have a right of representation in corporate decisions but current means of representation through the marketplace and through governmental guidance are limited in effect. Replacing the economic conception with a stakeholder model recognizing multiple forms of ownership and enabling wide-spread participation can help initiate important value debate leading to both economic and social benefits. But even with more stakeholder participation, value debate has not and will not necessary resulted. Many new programs have increased the number offorums in which representation and debate could occur, but have not increasedvoice. Richer conceptions of communication, negotiation, and rationality are necessary if we are to reform corporations in significant ways.     

Nuclear Safety in Ontario: A Critical Review of Quantitative Analyses

In this article quantitative analyses of CANDU nuclear generating stations are evaluated using an explicit set of criteria derived from a decision-analytic framework. A systematic search was made for relevant analyses, including both risk assessments and economic analyses. Only a small number of scientifically sound quantitative analyses that are being used to make decisions about specific safety measures or projects were located. The availability of scientifically sound quantitative data for making major energy policy decisions is even more limited, and what is available has major shortcomings. The province of Ontario is now heavily dependent on nuclear energy. Given the uncertainties surrounding the health, environmental, economic, and social consequences of nuclear energy, there is a need to assemble the information that is available within a comprehensive decision-making framework, and to decide future energy policies for the province in a public forum from a societal perspective.     

Effect of economic planning on business decisions

The fact that the United States has not faced an economic perplexity of current dimensions since the depression days hardly needs any emphasis. The current economic slowdown is significant because no recovery measures which may be applied to cure the economy are in sight. Since the Great Depression, especially after World War II, Keynes' economic theories have successfully been applied in the U.S., as also in other countries of the Free World, to put the economy back on path to recovery. Unfortunately, Keynesian measures do not seem to cope with the current economic woes. Apparently, new ways need to be sought and employed to get the economy back on track. Among many new ideas that have been advanced to restore economic growth, one is national economic planning by which the Government would play an active role in setting goals for the economy and devising means to reach them.The purpose of this paper is to report the findings of a study that the author undertook to probe the opinions of chief executive officers of the largest U.S. corporations on the whole idea of national economic planning in the United States. This study is based on interviews with 23 chief executives officers (CEOs) in different industries. Table 1 shows the background of these CEOs. Specifically, the author refers to such questions as: What positive and negative attitudes do the chief executive officers maintain toward national economic planning; what difficulties do they think will have to be surmounted to accomplish national economic planning in the U.S.; what influence may national economic planning have on various business decisions; and how may national economic planning affect corporate strategy?
