Lognormal Approximation of Complex Path-Dependent Pension Scheme Payoffs

Abstract

This paper analyzes an explicit return smoothing mechanism which has recently been introduced as part of a new type of pension savings contract that has been offered by Danish life insurers. We establish the payoff function implied by the return smoothing mechanism and show that its probabilistic properties are accurately approximated by a suitably adapted lognormal distribution. The quality of the lognormal approximation is explored via a range of simulation-based numerical experiments, and we point to several other potential practical applications of the paper's theoretical results.     

Efficiency Gains Under Exchange-Rate Emission Trading

In the case of emission of non-uniformly dispersed pollutants such as SO2 the negative effects depend on the location of the sources. A unit increase at one source must be compensated by either a larger or smaller reduction at another source to keep the negative effects at the same level. Emission trading between countries is possible under the Second Sulphur Protocol. Exchange rate trading and third party problems are studied within a simultaneous model facilitating impositions of various environmental constraints. Simulations based on the negotiated emission quotas are offered. Results indicate potential cost savings of 19%.     

Estimating SUR system with random coefficients: the unbalanced panel data case

A system of regression equations for analyzing panel data with random heterogeneity in intercepts and coefficients, and unbalanced panel data is considered. A maximum likelihood (ML) procedure for joint estimation of all parameters is described. Since its implementation for numerical computation is complicated, simplified procedures are presented. The simplifications essentially concern the estimation of the covariance matrices of the random coefficients. The application and ‘anatomy’ of the proposed algorithm for modified ML estimation are illustrated by using panel data for output, inputs and costs for 111 manufacturing firms observed up to 22 years.

Increased coordination in public transport—which mechanisms are available?

After several years of New Public Management reforms within public transport, coordination seems to receive increased attention. With examples of actual as well as suggested changes taken from Denmark, Sweden and the UK the aim of the article is to analyse and classify the mechanisms utilized and suggested to increase coordination between core stakeholders within passenger railway services and bus services. Four distinctive mechanisms of coordination are suggested, namely organisational coordination, contractual coordination, partnership coordination and discursive coordination. Each coordination mechanism has its strengths and failures. The article also debates to what extent the mechanisms conflict with three core characteristics of New Public Management: Unbundling of the public sector into corporatized units; more contract-based competitive provision; and greater emphasis on output controls.     

Reducing Demand for Litigation in Consumer Disputes—a Randomized Field Experiment with Social Information

It has long been argued that alternative dispute resolution is superior to traditional court litigation. The paper reviews traditional and behavioural arguments and findings for why litigation rates remain high. The paper then reports on a natural field experiment designed to test how to improve disputes between consumers and businesses in Denmark resolution by including social information into the dispute process. The experiment demonstrates that social information significantly affects litigants’ need for litigation, but that the effect on settlement rates is non-significant. The results are discussed along with suggestions for possible future research into improving the willingness to cooperate in consumer disputes.     

Consumer Preferences for ‘Localness’ and Organic Food Production

While organic food is based on well-defined production criteria, the criteria for ‘local’ food are less clear. This study investigates the preferences and trade-offs of distinct consumer segments relative to organic production and several dimensions of local food (sales channel, size of company, and geographical location of animals used in the production). The analysis is based on a quantitative survey of 505 Danish consumers and a choice experiment involving beef salami. Data were analyzed in a principal component and a latent class analysis. We identify five consumer segments whose preferences for organic and local product attributes differed substantially. Most respondents considered geographical proximity in the raising of cattle to be the most important attribute and a third of the consumers were willing to pay a premium for organic salami. The segmentation provides more detailed information about stated consumer behavior than what is typically elicited when considering only average consumer behavior.     

Born globals – presence,performance and prospects

The concept born global firms has gained a spectacular increase in interest from both academic and political circles. Rigorous quantitative treatment of born global firms are however rare in the international business/economics literature. Implementing unique data on all Swedish start-ups during 1998–2008 in the manufacturing sector, we conclude that born global firms are a very rare event, that their prevalence seems invariant to time, and that they perform similar to other matched “twin” firms with regard to profitability and productivity but report a considerably higher growth in employment and sales. These results are robust to a wider definition of born global firms and to the timing of performance measurements.     

Business ethics: Restrictive or empowering?

There is a tendency in the business ethics literature to think of ethics in restrictive terms: what one should not do, and how to control this. Drawing on Lawrence Kohlberg's theory of moral development, the paper focuses on, and draws attention to, another more positive aspect of ethics: the capacity of ethics to inspire and empower individuals, as well as groups. To understand and facilitate such empowerment, it is argued that it is necessary to move beyond Kohlberg's justice reasoning so as to appreciate the value and importance of feeling and care. Accordingly, we draw upon case study material to review the meaning of Kohlberg's higher stages — 5, 6 and 7 — to question the meaning of ethical reasoning. With such deeper understanding of particular ethical codes or practices, it is thought that members of organisations may come closer to thespirit, as opposed to the letter, of ethical conduct in organisations. This, we argue, is consistent with the degree of trust and integrity demanded by leaner, post-bureaucratic ways of organizing and conducting business as well as being personally beneficial to the people involved.Bjørn Kjonstad has recently completed his Masters dissertation.
