A Stochastic Control Approach to Risk Management Under Restricted Information

We use techniques from discrete-time stochastic control under partial state information to determine a shortfall-risk minimizing investment strategy in the case when there is only restricted information on the underlying market model and transaction costs as well as shortselling constraints are present. The approach is adaptive in the sense that it takes into account all the information on the underlying model that becomes successively available to an economic agent by observing the prices in the market. As an immediate byproduct of the approach it is possible to determine the entire shortfall distribution corresponding to the optimal strategy and to various values of the initial capital.     

Negotiation Support for Multi-Party Resource Allocation: Developing Recommendation for Decreasing Transportation-Related Air Pollution in Budapest

Decisions about how to allocate scarce resources among potential programs are common sources of conflict in both public and private life. This paper describes a case in which negotiation support was provided for a five-member task force trying to reach agreement about how to allocate limited resources among programs designed to improve the air quality in Budapest, Hungary. The intervention consisted of a series of facilitated decision conferences, plus individual interviews. The task force eventually reached agreement about a recommended package of 15 air quality management programs costing 1,500 million Hungarian forints. The research makes four significant contributions. First, it demonstrated that resource allocation models provide a useful framework for understanding and facilitating multi-party negotiation processes. Second, because resource allocation models were elicited individually for each group member before building a single group model, it was possible to analyze the five-dimensional feasible settlement space (i.e., the joint distribution of benefits for each task member for all possible resource allocation packages). Third, several innovative applications of analytical techniques (i.e., Pareto-efficiency analyses, numerical and graphical analyses of feasible settlement spaces and efficient frontiers, and analyses of task force members' investment progressions) served to improve understanding of disagreements within the group and to evaluate the quality of potential resource allocation packages. Fourth, changes in individual preferences and group agreement were assessed over time. Group members appeared to change substantially and their level of agreement to increase markedly over time.     

Offsetting the implicit incentives: Benefits of benchmarking in money management

Money managers are rewarded for increasing the value of assets under management. This gives a manager an implicit incentive to exploit the well-documented positive fund-flows to relative-performance relationship by manipulating her risk exposure. The misaligned incentives create potentially significant deviations of the manager’s policy from that desired by fund investors. In the context of a familiar continuous-time portfolio choice model, we demonstrate how a simple risk management practice that accounts for benchmarking can ameliorate the adverse effects of managerial incentives. Our results contrast with the conventional view that benchmarking a fund manager is not in the best interest of investors.     

The Impact of Option Popularity,Social Inclusion/Exclusion,and Self-affirmation on Consumers’ Propensity to Choose Green Hotels

Previous research on consumers’ willingness to choose a green hotel has yielded mixed results, with some studies indicating a positive relationship with the hotel’s CSR initiatives, while others suggesting that there is no booking advantage for hotels going green. The present research seeks to understand the social nature of green hotel booking decisions and proposes a conceptual framework elucidating three primary factors that underlie consumers’ propensity to choose a green hotel. The study findings indicate that, importantly, a consumer’s social relationship situation (social inclusion vs. social exclusion) with other consumers, self-affirmation (self-value/self-concept reinforcement), and the option popularity jointly influence consumers’ willingness to choose a green hotel. The authors adopt a 2 × 2 × 2 factorial experimental design to test the proposed hypotheses. Theoretical and managerial implications are discussed.

Discretionary enforcement and strategic interactions between enforcement agencies and firms: a theoretical and laboratory investigation

This paper presents a game theoretic morphological analysis of the strategic interactions between environmental enforcement authorities and polluting firms. The models explore the role of discretion that such authorities enjoy, either in deciding how to pursue environmental violations (investigative and prosecutorial discretion) or in judging them (judicial discretion). The purpose is to identify both the optimal firms’ behaviour in terms of compliance, and the enforcement authorities’ optimal strategies in terms of enforcement actions to undertake. Consistent with the setting of the game theoretic models, the role of the enforcement agencies in deterring firms from polluting is, then, empirically tested by means of laboratory experiments. Laboratory evidence on compliance behaviour of firms when faced with enforcement conditions predicted by the theoretical models set up is discussed for the different experimental treatments performed. Overall, we suggest that making environmental enforcement less predictable for the firms, and thus creating a degree of uncertainty for the violators, can actually encourage deterrence and, thus, improve compliance. Thus, a partly unpredictable enforcement strategy may generate more compliance than an environmental policy that is known with certainty in advance.     

The workplace lunch room: an arena for multicultural eating

Many countries in Europe have experienced growing migration since World War II. It is estimated that more than one in five Swedes living today has roots in other countries and cultures. Segregation in terms of ethnic origin in housing areas makes it easier to maintain the language and cultural traditions of the home country when it comes to cooking and eating. In extremely segregated housing areas, there may even be no interface between foreign cultural traditions and Swedish traditions in food consumption. Almost every inhabitant in the age range 20–65 years spends a number of years in workplaces outside the home. Workplaces are generally melting pots for employees of all ages and ethnic groups. In this study, a bus company lunch room served as a field for studying preferences in food, meals structure and eating patterns during lunch breaks. The city centre lunch room was visited by every driver at least once during their working day for coffee/tea, lunch or a rest. The lunch room served as an arena for discussions and exposure to new foods customs relating to meals and eating. It thus constituted a place for cultural exchange about food preferences and for forming opinions about individuals and nationalities, including Swedes. The methods for gathering empirical material for the analysis were participant observations and semi‐structured interviews. Food consumption can be recognized as a marker of class and status in the same way as consumption of leisure activities and clothing. Some new criteria in identifying members of we‐groups in relation to others can be added to the classical criteria. When language fails in communication, visible signs become more important. A workplace lunch room is a clear arena for attitude formation. Attitudes may be conservative or stereotyped but sometimes evoke the curiosity to eat something different. In a multicultural arena such as a workplace lunch room, the knowledge available about food, meals and preferences is sometimes far from the real truth, especially when visible impressions are not followed by verbal communication, which can sometimes lead to incomplete and narrow‐minded conclusions.     

The use of small instant loans among young adults – a gateway to a consumer insolvency?

The aim of this paper is to study 18‐ to 29‐year‐old Finnish consumers' use of instant small loans (i.e. SMS loan) and other consumer credit services that have increased notably in the past few years. We examine what kind of expenditures instant credit is used for and focus also on young consumers' financial situation and their perceptions of themselves as money handlers. The research method is quantitative, and data are derived from an open online survey (n = 1610). Our results reveal that consumer credit is used by young people in all income brackets and employment positions. However, there is a clear connection between certain life‐course stages (young, single parent), financial positions (low income), employment situations (marginal) and the propensity to take instant loans and consumer credit. The young people who take an instant loan once are likely to do it again. Typical purposes of use included buying alcohol, cigarettes and partying. For some consumers, the use of small loans is part of controlled and economical use of money. However, particularly in the low‐income brackets, it is also common to buy food and to repay credit or interest. Young people, who use instant loans recognize flaws in their money management and see themselves as ‘wasteful’ consumers more often than those who do not use instant loans. On the basis of this empirical study, it is unquestioned that young people's consumer education needs to be strengthened. In Finland, this need has already been recognized in both consumer policy and teacher education.     

A characterization of peanut consumption in four countries: results from focus groups and their implications for peanut allergy prevalence

Rates of peanut allergy in the Western world have increased over the last 30 years, although it is unclear why. While eating behaviours are likely to be connected to allergy prevalence, the precise relevant factors are uncertain. This study aimed to investigate dietary differences and changes in dietary habits in peanut consumption (in apparent and hidden forms) in four different countries (Bulgaria, Poland, Spain, UK), specifically chosen because of their different ‘peanut experiences’. Focus groups revealed a common perception that dietary habits have become less healthy, with more consumption of processed foods and an increase in snacking. In addition, ethnic cuisine was perceived to have had an important impact on European eating habits, while participants identified an increase in consumption of more ‘exotic’ forms of peanuts and their products. These findings point to an increase in exposure to peanuts, particularly in hidden forms, that superficially parallels increased prevalence rates. However, it was also clear that participants lacked knowledge about the composition of food and non‐food products. The dietary trends identified here thus warrant further quantitative investigation, particularly in the context of differential national patterns of allergy prevalence – data on which is currently being gathered within the EC‐funded EuroPrevall project.
