On planning and forecasting the location of retail and service activity

In countries with mixed economies, planning authorities cannot usually enforce micro location and travel decisions of urban activities, but are confined to forming macro location and transport policy, within which agents can operate according to the market. An attempt is made here to describe such multilevel behaviour of the planning authority, landlords, firms and customers, and to obtain non-cooperative equilibria in terms of the controls exerted by each group. The behaviour of the market groups is described via entropy maximization, while alternative modes of behaviour are ascribed to the authority. In addition, a Pareto-type solution is examined.     

DO STRATEGY AND MANAGEMENT MATTER IN MUNICIPAL ORGANISATIONS?

In Sweden, a large share of public services are organised, produced and delivered by municipalities, large and small, rich and poor. Contextual conditions (size and location) and economic conditions (efficiency and wealth) differ considerably among these service‐providing organisations. The question raised in this paper is whether a municipality's economic situation is a direct consequence of the contextual situation or the organisation's strategy and management – that is: Do strategy and management matter? Our analysis rests on a resource‐based view of organisation strategy. Both quantitative and qualitative observations have been made. First, cost savings data from 50 municipalities were examined for patterns and relationships between contextual and economic conditions. Second, about 100 representatives – municipal executive board members and leading officials – from 20 municipalities with different characteristics were interviewed. In this paper we outline an analytical framework and propose that sound and sustainable provision of municipal service depends on whether organisational decision‐making is in harmony with work methods and objectives. The results indicate that strategy and management do matter. Among the municipalities included in our study, we identify four prevalent basic strategies. Strategy tends to coincide with the economic situation rather than the contextual situation. A low‐performing municipality tends to have a predominantly outward orientation in its decision‐making, whereas a higher‐performing municipality makes decisions with both inward and outward orientation.     

Keeping others in our mind or in our heart? Distribution games under cognitive load

It has recently been argued that giving is spontaneous while greed is calculated (Rand et al., in Nature 489:427–430, 2012). If greed is calculated we would expect that cognitive load, which is assumed to reduce the influence of cognitive processes, should affect greed. In this paper we study both charitable giving and the behavior of dictators under high and low cognitive load to test if greed is affected by the load. This is tested in three different dictator game experiments. In the dictator games we use both a give frame, where the dictators are given an amount that they may share with a partner, and a take frame, where dictators may take from an amount initially allocated to the partner. The results from all three experiments show that the behavioral effect in terms of allocated money of the induced load is small if at all existent. At the same time, follow-up questions indicate that the subjects’ decisions are more impulsive and less driven by their thoughts under cognitive load.     

Knowledge maturity as a means to support decision making during product‐service systems development projects in the aerospace sector

Streamlining new product development forces companies to make decisions on preliminary information. This article considers this challenge within the context of project management in the aerospace sector and, in particular, for the development of product‐service systems. The concept of knowledge maturity is explored as a means to provide practical decision support, which increases decision makers' awareness of the knowledge base and supports cross‐boundary discussions on the perceived maturity of available knowledge, thereby identifying and mitigating limitations. Requirements are elicited from previous research on knowledge maturity in the aerospace industry, and a knowledge maturity model is developed through five industry‐based workshops.     

Gazelles as job creators: a survey and interpretation of the evidence

It is often claimed that small and young firms account for a disproportionately large share of net employment growth. We conduct a meta-analysis of the empirical evidence regarding whether net employment growth rather is generated by a few rapidly growing firms—so-called Gazelles—that are not necessarily small and young. Gazelles are found to be outstanding job creators. They create all or a large share of new net jobs. On average, Gazelles are younger and smaller than other firms, but it is young age more than small size that is associated with rapid growth. Gazelles exist in all industries. They seem not to be overrepresented in high-technology industries, but there is some evidence that they are overrepresented in services.     

Injuries sustained during snow removal from roofs resulting in hospital care

Clearing snow from roofs causes serious injuries annually. The aim of this study was to describe injury mechanisms, injury panorama, and injury incidence in connection to this activity. A specific aim was to study the association between snow depth and injury incidence. A total of 95 people were injured during four study periods. The risk of injury is strongly associated with snow depth, and the incidence varied up to 10-fold between the studied winter seasons. The majority of injuries (91; 96%) occurred during leisure time and only four people were injured in the occupational setting. The most common injury mechanism was falling off roofs or ladders of residential homes. Nearly 60% sustained moderate or serious injuries (Maximum Abbreviated Injury Scale [MAIS] 2–3), and fractures accounted for almost half of all injuries. Because roofs of single-family homes in Sweden usually do not require snow removal for heavy snow loads, these injuries may have been both unnecessary and avoidable. Further education is required to advise the public on the risks associated with snow removal from roofs.     

Pricing catastrophe risk in life (re)insurance

What is the catastrophe risk a life insurance company faces? What is the correct price of a catastrophe cover? During a review of the current standard model, due to Strickler, we found that this model has some serious shortcomings. We therefore present a new model for the pricing of catastrophe excess of loss cover (Cat XL). The new model for annual claim cost C is based on a compound Poisson process of catastrophe costs. To evaluate the distribution of the cost of each catastrophe, we use the Peaks Over Threshold model for the total number of lost lives in each catastrophe and the beta binomial model for the proportion of these corresponding to customers of the insurance company. To be able to estimate the parameters of the model, international and Swedish data were collected and compiled, listing accidents claiming at least twenty and four lives, respectively. Fitting the new model to data, we find the fit to be good. Finally we give the price of a Cat XL contract and perform a sensitivity analysis of how some of the parameters affect the expected value and standard deviation of the cost and thus the price.     

Social Behaviour in Work Absence*

By making use of a large‐scale randomized experiment, we test whether social behaviour is important for work absence due to illness. The individuals treated in the experiment were exposed to less monitoring of their eligibility to collect sickness insurance benefits, which sharply increased their non‐monitored work absence. This exogenous variation is exploited in two complementary analyses. In both analyses, we find significant social‐behaviour effects. Using detailed data, we conclude that the social‐behaviour effects most likely stem from fairness concerns.     

Externalization of employees: thinking about going somewhere else

Externalization of employment relations was a general trend among businesses in the 1990s. As a consequence we observe an increasing use of temporary workers, outsourcing and insourcing. This paper is concerned with the consequences of externalization of employment relations from the perspective of employees. The paper is based on an in-depth empirical study of a corporate adjustment programme in a large government-owned energy producer in Sweden. The company is trying to stimulate internal mobility by means of training programmes, adjusting its workforce to changes in market demand without lay-offs. I argue that externalization of employment relations is not only a matter of temporary, administrative or geographical distance between employer and employee. Instead a complementary form - externalization of responsibility - is suggested. The results may have consequences for the understanding of human resource policies aiming at employability.     

An empirical model for durations in stocks

This paper considers an extension of the univariate autoregressive conditional duration model to which durations from a second stock are added. The model is empirically used to study duration dependence in four traded stocks, Nordea, Föreningssparbanken, Handelsbanken and SEB A on the Stockholm Stock Exchange. The stocks are all active in the banking sector. It is found that including durations from a second stock may add explanatory power to the univariate model. We also find that spread changes have significant effect for all series.
