Yu, Mingzhu, Jan C. Fransoo and Chung-Yee Lee (2018): Detention Decisions for Empty Containers in the Hinterland Transportation System, Transportation Research. Part B: Methodological, 110 (188-208).
Abstract: In this paper, we study a hinterland empty container transportation system<br/>which consists of a sea container terminal and an inland container terminal. There are a hinterland container operator who is in charge of the hinterland container transportation and an ocean carrier who has an empty container depot at the sea container terminal. We utilize a two-stage game model to describe the ocean carrier’s decision about the container’s free detention time and the hinterland container operator’s decision about the time when should an arrived empty container at the inland terminal be dispatched to the sea terminal. Optimal delivery policy of the empty container and the ocean carrier’s optimal free detention time are derived. It is shown that the decentralized system does not guarantee system coordination all the time. The ocean carrier has incentive to integrate the hinterland transportation operation only if the hinterland area is not very short of empty containers.
van Pelt, Thomas D. and Jan C. Fransoo (2018): A note on “Linear programming models for a stochastic dynamic capacitated lot sizing problem”, Computers & Operations Research, 89 (January): 13-16.
Abstract: Tempelmeier and Hilger (2015) study the stochastic dynamic lot sizing problem with multiple items and limited capacity. They propose a linear optimization formulation for the problem based on a piece-wise linear approximation of the non-linear functions for the expected backorders and the expected inventory on hand. Building on the work of Tempelmeier and Hilger (2015), we correct an erroneous derivation of the linear optimization problem and propose an improved model.
Transchel, Sandra (2017): Inventory Management Under Price-Based and Stockout-Based Substitution, European Journal of Operational Research, 262 (3): 996-1008.
Abstract: We examine a stochastic inventory and pricing problem for a firm that sells two vertically differentiated products. The demands for the two products are determined by total (random) market size and the customers’ net utility from buying the two products, which is determined by the products’ quality attributes, the individual quality valuation (unknown to the firm), and the selling prices. In case the preferred product is out of stock, customers may be willing to buy a substitute instead, if their net utility is non-negative. Therefore, we analyze an inventory and pricing model, considering price-based and stockout-based substitution.We show that the demand function is not continuous in price. By decomposing the profit function into different price regimes, we are able to derive closed-form expressions for the stockout-based substitution rates (upward and downward substitution) and the optimal inventory levels under exogenous pricing. Under endogenous pricing, we find that the profit function is not necessarily unimodal. However, we show that a unique solution exists for the integrated price and inventory problem under price-based substitution only. Numerical results reveal that not considering stockout-based substitution (i) leads to lower profit margins for high-quality products and (ii) may cause severe supply-demand mismatches throughout the entire assortment. Finally, we show the performance of two approximated pricing policies.

Christensen, Björn and Alexander Himme (2017): Improving Environmental Management Accounting: How to Use Statistics to Better Determine Energy Consumption, Journal of Management Control, 28 (2): 227-243.
Abstract: The accounting literature voices increased concerns about sustainability issues. Environmental performance as one dimension of sustainability includes among others the management and control of energy. Energy is a key production factor to which the stakeholders of a firm pay increased attention. Since energy has a significant influence on the economic costs and the environmental footprint of firms, management accounting is under growing pressure to better monitor and control energy costs. As a consequence, management accounting needs to develop energy management systems which control energy consumption and aim to reduce energy costs which in turn diminish a firm’s environmental impact and thus improve corporate reputation. One of the most important elements for energy management systems is an effective and cost-efficient measure of the energy consumption. However, firms and their management accounting departments, respectively, are still struggling to develop any cost-efficient approach for measuring energy consumption. That is why we suggest a statistical approach to easily and cost-efficiently measure energy utilization which in turn provides information input to improve environmental management accounting (e.g., cost allocations). We demonstrate our approach for a firm from an energy-intensive industry. The approach allows to distinguish more efficient from less efficient production units. We derive implications from this measurement approach for environmental management accounting and environmental management control systems.
Udenio, Maximiliano, Eleni Vatamidou, Jan C. Fransoo and Nico P. Dellaert (2017): Behavioral causes of the bullwhip effect: an analysis using linear control theory, IISE Transactions, 49 (10): 980-1000.
Abstract: It has long been recognized that the bullwhip effect in real life depends on a behavioral component. However, non-experimental research typically considers only structural causes in its analysis. In this paper, we study the impact of behavioral biases on the performance of inventory/production systems modeled through an APVIOBPCS (Automatic Pipeline, Variable Inventory, Order Based Production Control System) design using linear control theory. To explicitly model managerial behavior, we allow independent adjustments to inventory and pipeline feedback loops. We consider the biases of smoothing/over-reaction to inventory and pipeline mismatches, and the under/over-estimation of the pipeline. To quantify the performance of the system, we first develop a new procedure to determine the exact stability region of the system and we derive an asymptotic stability region that is independent of the lead time. Afterwards, we analyze the effect of different demand signals on order and inventory variations. Our findings suggest that normative policy recommendations must take demand structure explicitly into account. Finally, through extensive numerical experiments, we find that the performance of the system depends on the combination of the behavioral biases and the structure of the demand stream.
McKinnon, Alan C. (2017): Starry-eyed II: the logistics journal ranking debate revisited, International Journal of Physical Distribution & Logistics Management, 47 (6): 431-446.
Abstract: Purpose In a previous paper (McKinnon, 2013), the author questioned the principle and practice of journal ranking and discussed its effects on logistics research. Since then several important developments have occurred prompting a fresh review of the issues. The paper summarises the results of this review with the aim of stimulating further discussion on the subject. Design/methodology/approach New literature on the journal ranking debate has been reviewed. The validity of the journal ranking as a proxy measure of paper quality is explored using data from the UK Research Excellence Framework (REF) assessment. Changes to the ranking of ten logistics/supply chain management (SCM) journals in four listings are analysed, and possible reasons for the relatively low status of the journals are examined. Findings The influence of journal rankings on the academic research process is strengthening while the debate about their legitimacy has intensified. UK REF data cast doubt on the reliability of the journal ranking as an indicator of a paper’s merit. Logistics/SCM journals continue to occupy mid-to-lower tier positions in most listings, though there has been some improvement in their standing. Research limitations/implications The paper aims to alert those managing and undertaking logistics research to the dangers of overreliance on journal rankings in the measurement of research quality and productivity. Practical implications The paper may help logistics/SCM scholars to defend the position of their discipline and resist journal-ranking-induced pressures to marginalise it and devalue its outputs. Social implications In this paper, academic recruitment, promotion and motivation are considered. Originality/value The paper sheds new light on the relationship between journal ranking and individual paper quality, on recent changes in the rating of logistics/SCM journals and on the wider debate about the use of bibliometrics in assessing research quality.
Kosmas, Vasileios and Michele Acciaro (2017): Bunker levy schemes for greenhouse gas (GHG) emission reduction in international shipping, Transportation Research Part D: Transport and Environment, 57: 195-206.
Abstract: A fuel levy is one of the market-based measures (MBMs) currently under consideration at the International Maritime Organization. MBMs have been proposed to improve the energy efficiency of the shipping sector and reduce its emissions. This paper analyses the economic and environmental implications of two types of levy on shipping bunker fuels by means of an analytical model built on the cobweb theorem. A unit-tax per ton of fuel and an ad-valorem tax, enforced as a percentage of fuel prices, are examined. In both cases, a speed and fuel-consumption reduction equivalent to an improvement in the energy efficiency of the sector would be expected as a result of the regulation enforcement. The speed reduction in the unit-tax case depends on fuel prices and the tax amount, whereas in the ad-valorem case it relies upon the enforced tax percentage.Both schemes lead to industry profit decline, the extent of which depend on the structure of the levy and market conditions. Since there is concern that the costs resulting from the policy will be passed from shipping companies to their customers along the supply chain, the paper dwells on how the costs arising from the enforcement of the levy will be actually allocated between ship-owners and operators, and cargo-owners. In a market characterised by high freight rates and with no or limited excess capacity, a higher percentage of the total tax amount is transferred from ship-owners to shippers. In case of a recession the opposite happens.
Ullrich, Kristoph and Sandra Transchel (2017): Demand-Supply Mismatches and Stock Market Performance: A Retailing Perspective, Production and Operations Management, 26 (8): 1444-1462.
Abstract: We provide empirical evidence that the volatility of inventory productivity relative to the volatility of demand is a predictor of future stock returns in a sample of publicly listed U.S. retailers over the period 1985–2013. This key performance indicator, entitled demand–supply mismatch (DSM), captures the fact that low variation in inventory productivity relative to variation in demand is indicative of the superior synchronization of demand- and supply-side operations. Applying the Fama and French (1993) three-factor model augmented with a momentum factor (Carhart 1997), we find that zero-cost portfolios formed by buying the two lowest and selling the two highest quintiles of DSM stocks yield abnormal stock returns of up to 1.13%. These strong market anomalies related to DSM are observed over the entire sample period and persist after controlling for alternative inventory productivity measures and firm characteristics that are known to predict future stock returns. Further, we reveal that DSM is indicative of lower future earnings and lower sales growth and provide evidence that the observed market inefficiency results from investors’ failure to incorporate all of the information that inventory contains into the pricing of stocks.
Schnittka, Oliver, Alexander Himme, Dominik Papies and David Pellenwessel (2017): Are sponsors blamed for edging off? Consumer reactions to sponsorship terminations, Journal of Business Economics, 87 (7): 943-984.
Abstract: Firms regularly terminate sponsorships, even without publicly known misconduct by the sponsee such as athlete doping. Consumer reactions to these sponsorship terminations by firms have not been studied despite being a regular occurrence. Using a set of experimental studies, this paper analyzes consumer reactions to these sponsorship terminations (i.e., early and non-renewal) that were not caused by a sponsee’s misconduct, the underlying process that causes the reactions, and the role of several moderating factors (trust, power balance, and locus of control). Our findings reveal that sponsorship terminations have a negative effect on sponsors’ brand images‐-particularly early terminations that occur before the end of a contract‐-because consumers perceive these sponsorship terminations as unfair. The results also suggest that a termination is particularly harmful for the sponsor’s perceived fairness if the sponsor is powerful and if the termination decision is under the sponsor’s control. Further, the termination effect is particularly strong for firms that consumers trust.
Jelinek, Lena, Niels Van Quaquebeke and Steffen Moritz (2017): Cognitive and Metacognitive Mechanisms of Change in Metacognitive Training for Depression, Scientific Reports, 7 (3449).
Abstract: Metacognitive Training for Depression (D-MCT), a low-threshold group intervention, has been shown to improve depressive symptoms. It aims at the reduction of depression by changing dysfunctional cognitive as well as metacognitive beliefs. The purpose of the present study was to investigate whether the mechanisms of change in D-MCT are cognitive (and thus primarily concern the content of cognition) or metacognitive in nature. Eighty-four outpatients with depression were included in a randomized controlled trial comparing D-MCT to an active control intervention. Level of depression, dysfunctional cognitive beliefs (DAS), and metacognitive beliefs (MCQ subscales: Positive Beliefs, Negative Beliefs, Need for Control) were assessed before (t0) and after treatment (t1). Severity of depression was also assessed 6 months later (t2). Linear regression analyses were used to determine whether change in depression from t0 to t2 was mediated by change in cognitive vs. metacognitive beliefs from t0 to t1. D-MCT’s effect on change in depression was mediated by a decrease in dysfunctional metacognitive beliefs, particularly ‘need for control’. Our findings underline that one of the key mechanisms of improvement in D-MCT is the change in metacognitive beliefs. The current study provides further support for the importance of metacognition in the treatment of depression.
Flöthmann, Christoph and Kai Hoberg (2017): Career Patterns of Supply Chain Executives: An Optimal Matching Analysis, Journal of Business Logistics, 38 (1): 35-54.
Abstract: This exploratory study analyzes the careers of 307 supply chain executives (SCEs). Motivated by career theory, our findings create new knowledge about the educational backgrounds and career paths that lead to SCE positions. Based on an optimal matching analysis, we are able to distinguish among six career patterns for SCEs. They differ in terms of the individuals’ previous professional experience, educational background, and the time they needed to arrive in an executive position. By characterizing the backgrounds and career paths of SCEs, we show that supply chain management (SCM) is truly a cross-functional profession. Our findings suggest that previous staff responsibility appears to be a more important hiring criterion than extensive SCM experience. While 56% of the executives had prior staff responsibility, only 12% of the cumulated careers were actually spent inside the SCM function.
Gläser, Daniel, Suzanne van Gils and Niels Van Quaquebeke (2017): Pay-for-performance and interpersonal deviance: Competitiveness as the match that lights the fire, Journal of Personnel Psychology, 16: 77-90.
Abstract: Many organizations use Pay-for-Performance (PfP) programs in order to fuel employee motivation and performance. In the present article, we argue that PfP may also increase employees’ interpersonal deviance (i.e., active harming behavior towards co- workers) because it might induce social comparison and competition. In order to uncover the underlying process, we further argue that this effect should be particularly pronounced for employees who are high in individual competitiveness, i.e., employees who have a strong desire for interpersonal comparison and aspire to be better than others. A cross-sectional field study (N=250) and two experiments (N=92; N=192) provide support for our interaction hypothesis. We discuss the theoretical implications regarding PfP and competitiveness, and offer suggestions concerning the practical implementation of PfP.
Acciaro, Michele, Andrea Bardi, Maria Ines Cusano, Claudio Ferrari and Alessio Tei (2017): Contested port hinterlands: An empirical survey on Adriatic seaports, Case Studies on Transport Policy, 5 (2): 342-350.
Abstract: Ports compete not only on the sea-side (e.g. through terminal investments, increase in terminal efficiency, maritime service connectivity) but also on the land-side (e.g. through logistics chain, advanced IT services, door-to-door connectivity). On this issue, several studies (e.g. Meersman et al., 2009; Tongzon, 2009) recently pointed out the increasing importance of the connectivity – at both quality and quantity level – between the port and its own hinterland in order to be competitive in the modern maritime service structure.The analysis concentrates on the study of the port hinterland contestability and on the definition of the catchment area focusing on a case study (i.e. the Adriatic ports aiming at attracting the Southern German freight flows) in order to better understand which elements affect the possibility to expand the current ports’ hinterland.The empirical research is based on public statistics (e.g. Eurostat, Amadeus database) and on data directly collected from the operators currently serving Southern German firms with the main commercial ports and with the potential port actors that may be interested in an enlargement of the port catchment area in the studied region (e.g. South European ports). Apart from the trade pattern analysis – based on the general statistics – and the logistics structure analysis – based on the information collected by transport and logistics operators –, a direct survey has been conducted on a sample of manufacturing companies located in Southern Germany and Western Austria in order to understand what actions should be taken in order to promote the use of Adriatic ports and then reshape the boundaries of the catchment areas of these ports. Statistical tools and a bottom-up approach have been developed in order to evaluate the results. Main findings are then related to potential strategies that may fill in the competitive gap between Northern and Southern European ports when they compete to serve the same hinterland. The original contribution of the research is an insight on the relative importance of the infrastructure endowment, the generalized transport cost and also of some non-monetary conditions – as cultural and behavioural aspects – that have an influence in determining the effective boundaries of ports’ hinterland.
Leenders, Bart P.J., Velázquez Martínez, Josué C. and Jan C. Fransoo (2017): Emissions allocation in transportation routes, Transportation Research. Part D: Transport and Environment, 57: 39-51.
Abstract: This article studies the allocation of CO2 emissions to a specific shipment in routing transportation. The authors show that this problem differs from a cost allocation problem specifically because the concavity condition does not hold necessarily in the CO2 allocation problem. This implies that a traditional cost allocation method cannot be straightforwardly translated into a CO2 allocation problem, and thus, new methods need to be developed. This study proposes four allocation mechanisms that are extensions from the literature and the common practice in industries. In doing so, the authors introduce the concept of carbon efficiency to assess if a particular allocation rule drives companies to carbon emissions reduction. They present analytical properties that show that the current practice of allocating CO2 emissions based on the greenhouse gas protocol, fails to be sensitive to drive companies to the sustainable practice of placing consolidated orders. The authors also conduct an experimental analysis using data of a logistics service provider that operates in Europe. Using the results of the experiments, they show that simple allocation methods can lead to a fair and carbon efficient allocation. In addition, the study provides insights by conducting a sensitivity analysis, and it shows that the CO2 allocations are not substantially susceptible to shipment size estimation errors.
Lu, Tao, Jan C. Fransoo and Chung-Yee Lee (2017): Carrier portfolio management for shipping seasonal products, Operations Research, 65 (5): 1250-1266.
Abstract: Many seasonal products are transported via ocean carriers from origin to destination markets. The shipments arriving earlier in the market may sell at higher prices, but faster shipping services can be costly. In this paper, we study a newsvendor-type shipper who transports and sells seasonal products to an overseas market, where the selling price declines over time. A set of vessels with different schedules and freight rates are available to choose from. Our analysis demonstrates that a portfolio of vessels has two distinct effects on mitigating uncertainties in both demand and vessels’ arrival schedules, while these two portfolio effects have been previously understood as separate issues in the literature. To find the optimal portfolio in our problem,we first show that when vessels arrive in a deterministic sequence, the optimal portfolio can either be derived in closed form (in the single-demand setting) or computed efficiently with a variation of the shortest-path algorithm (in the multi-demand setting). Then, based on these results, we propose an approximation procedure to address the general problem with an uncertain arrival sequence. In each iteration of the procedure, we only need to minimize a cost function approximated by a deterministic arrival schedule and the portfolio generated can converge to the optimal one under mild conditions. Finally, we present a real-world case studyto demonstrate several practical implications of managing a carrier portfolio.
Inderfurth, Karl, Ian M. Langella, Sandra Transchel and Stephanie Vogelgesang (2017): A heuristic solution method for disassemble-to-order problems with binomial disassembly yields, International Journal of Production Economics, 185: 266-274.
Abstract: In disassemble-to-order problems, where a specific amount of several components must be obtained from the disassembly of several types of returned products, random disassembly yields create a formidable challenge for appropriate planning. In this context, it is typically assumed that yields from disassembly are either stochastically proportional or follow a binomial process. In the case of yield process misspecification, it has been shown (see Inderfurth et al. (2015)) that assuming binomial yields usually results in a lower penalty than assuming stochastically proportional yields. While there have been heuristics developed for the disassemble-to-order problem with stochastically proportional yields, a suitable, powerful heuristic for binomial yields is needed in order to facilitate solving problems with complex real-world product structures. We present a heuristic approach that is based on a decomposition procedure for the underlying non-linear stochastic optimization problem and that can be applied to problems of arbitrary size. A comprehensive numerical performance study using both randomly generated instances as well as a full factorial experimental design and, additionally, the data of a practical case example reveals that this heuristic delivers close-to-optimal results.
Reh, Susan, Niels Van Quaquebeke and Steffen R. Giessner (2017): The aura of charisma: A review on the embodiment perspective as signaling, The Leadership Quarterly, 28: 486-507.
Abstract: Charismatic leaders have consistently been shown to affect followers’ performance, motivation, and satisfaction. Yet, what precisely constitutes charisma still remains somewhat enigmatic. So far, research has mainly focused on leader traits, leader behaviors, or the leader follower- relationship, and the subsequent consequences of each on followers’ self-concepts. All of these approaches share the notion that leader charisma depends on an explicit interaction between leader and follower. With the present review paper, we extend extant theorizing by arguing that charisma is additionally informed by embodied signals that flow directly from either the leader or the immediate environment. We introduce the embodiment perspective on human perception and describe its utility for theoretically understanding the charismatic effect. Correspondingly, we review studies that show which concrete embodied cues can support the charismatic effect. Finally, we discuss the variety of new theoretical and practical implications that arise from this research and how they can complement existing approaches to charismatic leadership.
Fischer, Marc and Alexander Himme (2017): The Financial Brand Value Chain: How Brand Investments Contribute to the Financial Health of Firms, International Journal of Research in Marketing, 34 (1): 137-153.
Abstract: Marketing and finance executives follow different objectives and focus on different stakeholder groups. Marketers want to create sales impact. Finance executives are concerned about the financial health of the firm. As a result, both worlds tend to be rather disconnected in their daily business. We argue that this does not reflect the dynamics of the firm where important marketing and financial metrics in fact interact. As long as marketing and finance officers do not fully appreciate the interplay of their key metrics, their decisions are likely to be suboptimal.This article proposes a simultaneous equation model that reflects the interaction of marketing and finance-domain variables in the value creation process. We focus on brand-building activities and the attraction of capital as major tasks of marketing and finance officers. Our model shows how advertising and other investments increase customer-based brand equity (CBBE) that in turn impacts financial leverage and credit spread and ultimately elevates the level of financial resources.Based on a broad sample of 155 firms covering various B2C industries, we test for the empirical relevance of our model. We also assess the practical significance of our results by transforming them into elasticities. Our results suggest that marketing and finance executives need to consider the dynamic interaction of their decision and performance variables to fully evaluate the effects of their decisions on the firm's financial health.
Mölders, Christina, Niels Van Quaquebeke and Maria P. Paladino (2017): Consequences of Politicians’ Disrespectful Communication Depend on Social Judgment Dimensions and Voters’ Moral Identity, Political Psychology, 38 (1): 119-135.
Abstract: The present study investigates the consequences of respectful versus disrespectful communication in political debates on voters’ social judgments and voting decisions. Reconciling previously mixed results, we argue that the consequences of disrespect vary with the judgment dimension (communion vs. agency) and voters’ moral identity. An initial study (N = 197) finds that a political candidate's disrespect towards his or her opponent affects voting decision through voting intention. A second study (N = 327) shows that disrespect influences voting intention through communion but not through agency ratings. Qualifying the previous finding, a third study (N = 329) shows that both communion and agency judgments act as mediators, but in different ways depending on the level of moral identity. Overall, communion judgments played a more prominent part in explaining the consequences of disrespectful communication. Our findings thus present a nuanced picture of respect and disrespect in political communication and shed light on their ramifications.
Meyners, Jannik, Christian Barrot, Jan U. Becker and Jakob Goldenberg (2017): The Role of Mere Closeness: How Geographic Proximity Affects Social Influence, Journal of Marketing, 81 (5): 49-66.
Abstract: Geographic proximity has become increasingly relevant due to the growing number of marketing services that use consumers’ geographic locations, thus increasing the importance of gaining insights from this information. In five studies (both field and experimental), the authors analyze the effect of geographic proximity on social influence and demonstrate that not only social proximity but also perceived homophily can trigger social influence. They find that this effect holds under alternative representations of geographic distance and is confirmed for a range of different services and even for physical goods. Furthermore, the authors show that geographic proximity has a relative effect because the social influence of a closer sender is stronger than that of a more distant sender, regardless of the absolute distances. They present managerially relevant conditions under which the influence of geographic proximity not only is comparable to other types of information such as age or gender but also provides sufficient informational value for customers to offset differences among alternatives (e.g., due to higher prices) in trade-off decisions.
Gambardella, Alfonso, Christina Raasch and Eric von Hippel (2017): The User Innovation Paradigm: Impacts on Markets and Welfare, Management Science, 63 (5): 1450-1468.
Abstract: Innovation has traditionally been seen as the province of producers. However, theoretical and empirical research now shows that individual users—consumers—are also a major and increasingly important source of new product and service designs. In this paper, we build a microeconomic model of a market that incorporates demand-side innovation and competition. We explain the conditions under which firms find it beneficial to invest in supporting and harvesting users’ innovations, and we show that social welfare rises when firms utilize this source of innovation. Our modeling also indicates reasons for policy interventions with respect to a mixed user and producer innovation economy. From the social welfare perspective, as the share of innovating users in a market increases, profit-maximizing firms tend to switch “too late” from a focus on internal research and development to a strategy of also supporting and harvesting user innovations. Underlying this inefficiency are externalities that the producer cannot capture. Overall, our results explain when and how the proliferation of innovating users leads to a superior division of innovative labor involving complementary investments by users and producers, both benefitting producers and increasing social welfare.
Kalyanarengan Ravi, Narayen, van Sint Annaland, Martin, Jan C. Fransoo, Johan Grievink and Edwin Zondervan (2017): Development and implementation of supply chain optimization framework for CO2 capture and storage in the Netherlands, Computers and Chemical Engineering, 102: 40-51.
Abstract: In this work, we develop a mixed integer linear optimization model that can be used to select appropriate sources, capture technologies, transportation network and CO2 storage sites and optimize for a minimum overall cost for a nationwide CO2 emission reduction in the Netherlands. Five different scenarios are formulated by varying the location of source and storage sites available in the Netherlands. The results show that the minimum overall cost of all scenarios is €47.8 billion for 25 years of operation and 54 Mtpa capture of CO2. Based on the investigated technologies, this work identifies Pressure Swing Adsorption (PSA) as the most efficient for post-combustion CO2 capture in the Netherlands. The foremost outcome of this study is that the capture and compression is the dominant force contributing to a majority of the cost.KeywordsCarbon capture; CO2 reduction; Supply chain; Optimization; CCS; Mathematical model
van Gils, Suzanne, Michael A. Hogg, Niels Van Quaquebeke and Daan van Knippenberg (2017): When Organizational Identification Elicits Moral Decision-Making: A Matter of the Right Climate, Journal of Business Ethics, 142 (1): 155-168.
Abstract: To advance current knowledge on ethical decision-making in organizations, we integrate two perspectives that have thus far developed independently: the organizational identification perspective and the ethical climate perspective. We illustrate the interaction between these perspectives in two studies (Study 1, N = 144, US sample; and Study 2, N = 356, UK sample), in which we presented participants with moral business dilemmas. Specifically, we found that organizational identification increased moral decision-making only when the organization’s climate was perceived to be ethical. In addition, we disentangle this effect in Study 2 from participants’ moral identity. We argue that the interactive influence of organizational identification and ethical climate, rather than the independent influence of either of these perspectives, is crucial for understanding moral decision-making in organizations.
Merkle, Christoph, Philipp Schreiber and Martin Weber (2017): Framing and Retirement Age: The Gap between Willingness-to-Accept and Willingness-to-Pay, Economic Policy, 32 (92): 757-809.
Abstract: In a large online experiment, we relate the retirement timing decision to the disparity between the willingness-to-accept (WTA) and the willingness-to-pay (WTP). In the WTP treatment, participants indicate the maximum amount of monthly benefits they are willing to give up in order to retire early. In the WTA treatment, the minimum increase of monthly payments in order to delay retirement is elicited. Our results reveal that the framing of the decision problem strongly influences participants' reservation price for early retirement. The willingness-to-accept for early retirement is more than twice as high as the corresponding willingness-to-pay. Using actual values from the German social security system as market prices, we demonstrate that the presentation in a WTA frame can induce early retirement. In this frame, the implicit probability of retiring early increases by 30 percentage points.We further show that the disparity between WTA and WTP is correlated with loss aversion. Repeating the analysis with data from a representative household survey (German SAVE panel), we find similar results.
