Consumption theory with reference dependent utility

This paper presents a closed form consumption function for an individual when his utility depends both on his own current and previous consumption and on the consumption by his relevant others. Given this model, I argue that we can introduce an alternative definition of marginal propensity to consume (MPC) in addition to the traditional definition. This alternative definition can be called the individual’s total MPC, which I show is smaller than the traditional MPC.     

Sex composition of children as a determinant of marriage disruption and marriage formation: Evidence from Swedish register data

This paper investigates the effect of sex composition of children on the propensity of Swedish mothers to enter and leave marriage. Swedish population-register data are used to estimate relative risks of marriage formation and marriage dissolution for mothers with different numbers and sexes of children. The large number of observations allows us to get a very accurate picture of such relationships even if they are relatively weak. Morganet al. (1988) used survey data for the US and claimed to have found that one- and two-child parents in that country had lower divorce risks if they had sons than if they had daughters. For Sweden, we find only a minor effect in the same direction for three-child mothers. For two-child mothers, we instead find that the divorce risk is slightly reduced if a woman has one child of each sex. The divorce risk of one-child mothers is not at all affected by the sex of the child. Finally, the sex composition of children has no effect on the propensity of Swedish mothers to enter the married state.     

Visual challenges using Visual Display Units (VDU) in office landscapes

A total of 85 VDU operators, in three main Scandinavian Alcatel-Lucent headquarters, were followed in a process moving from single occupancy offices to an office landscape. This paper discusses the visual challenges and implications in such a transfer. In the oral presentation recommendation on how to avoid visual problems will be given.     

Varieties of Democracy: Interest Groups and Corporatist Committees in Scandinavian Policy Making

Corporatism may be seen as variety of capitalism in which specific structural prerequisites such as unionization, centralization, and strong states combined with bargaining and concertation produce certain economic outputs. Corporatism may also be seen as a variety of democracy in which interest groups are integrated in the preparation and/or implementation of public policies. Departing in the last position, we measure the strength of Scandinavian corporatism by the involvement of interest groups in public committees, councils, and commissions. Corporatism in relation to the preparation of policy has gone down in all three Scandinavian countries whereas corporatism in implementation processes are more varied among the three countries.     

Organizational capacity and entrepreneurial behavior

In this research note, we examine the relationship between organizational capacity and entrepreneurial behavior in a global sample of 165 nonprofit organizations operating in a single, rapidly growing field of nonprofit activity. Our findings show a strong relationship between organizations' entrepreneurial behavior and levels of organizational capacity. We discuss our results relative to the importance of both organizational capacity and entrepreneurial behavior in a rapidly growing nonprofit subsector. The results contribute to the continued development and refinement of theoretical and empirical work on the causal links between organizational capacity and entrepreneurial behavior more generally.     

Inference for cluster point processes with over- or under-dispersed cluster sizes

Cluster point processes comprise a class of models that have been used for a wide range of applications. While several models have been studied for the probability density function of the offspring displacements and the parent point process, there are few examples of non-Poisson distributed cluster sizes. In this paper, we introduce a generalization of the Thomas process, which allows for the cluster sizes to have a variance that is greater or less than the expected value. We refer to this as the cluster sizes being over- and under-dispersed, respectively. To fit the model, we introduce minimum contrast methods and a Bayesian MCMC algorithm. These are evaluated in a simulation study. It is found that using the Bayesian MCMC method, we are in most cases able to detect over- and under-dispersion in the cluster sizes. We use the MCMC method to fit the model to nerve fiber data, and contrast the results to those of a fitted Thomas process.

     

The lambda model and “rule of thumb” consumers: An estimation problem in existing studies

Campbell and Mankiw's (1990) lambda model has frequently been used to estimate the fraction of rule of thumb consumers (i.e., consumers who do not smooth their consumption). However, the present note shows theoretically, as well as with a numerical illustration, that existing empirical applications of the lambda model imply a systematic underestimation of this fraction. The reason is that per capita values instead of aggregate values (which the model is designed for) are used.
