Swedish Multinationals and Competition from High- and Low-Wage Locations

This study uses data on Swedish multinationals to estimate cross-elasticities of labor demand in different locations. With a vertical decomposition of the firm's activities, whether there is substitution or complementarity between employment in different parts of the firm will depend on whether wage changes lead to a relocation of activities or simply to changes in marginal costs and/or demand for inputs in other parts of the firms. It is found that there is some evidence of a substitutionary relationship between employment in the Swedish parts of the firms and employment in other high-income locations, but no evidence of substitution stemming from employment in low-income locations.     

Estimation of an adaptive stock market model with heterogeneous agents

Standard asset pricing models based on rational expectations and homogeneity have problems explaining the complex and volatile nature of financial markets. Recently, boundedly rational and heterogeneous agent models have been developed and simulated returns are found to exhibit various stylized facts, such as volatility clustering and fat tails. Here, we are interested in how well the proposed models can explain all the properties seen in real data, not just one or a few at a time. Hence, we do a proper estimation of some simple versions of such a model by the use of efficient method of moments and maximum likelihood and compare the results to real data and more traditional econometric models. We discover two main findings. First, the similarities with observed data found in earlier simulations rely crucially on a somewhat unrealistic modeling of the noise term. Second, when the stochastic is more properly introduced the models are still able to generate some stylized facts, but the fit is generally quite poor.     

Anchoring Induced Biases in Consumer Price Negotiations

Two studies were conducted with the aim of demonstrating anchoring induced biases in consumer price negotiations.In Study 1, 96 undergraduate students of business administration who were recruited as subjects played the role of buyers of a condominium. All subjects were given the same market information. They were then asked to state whether their reservation price was higher or lower than an arbitrary price example (irrelevant anchor) that for different groups of subjects was either low or high. Finally, subjects indicated their reservation price. As would be predicted if adjustments from the anchor are insufficient, the indicated reservation price was lower when the anchor was low than when it was high.In Study 2, employing 64 undergraduate students of psychology who conducted dyad negotiations about the price of condominiums, the effect of the irrelevant anchor on the initially indicated reservation price was replicated. In addition, an anchoring effect of the seller's initial offer was observed. The results also revealed effects of both irrelevant anchor and initial offer on the purchase price.From a public policy point of view, the results imply that consumers may be strongly influenced by irrelevant anchors provided by sellers. Provision of accurate market price information may however lessen the impact of irrelevant anchors.     

The third way: The repositioning of the voluntary sector

This paper explores some of the ways in which the voluntary sector can enter into a series of professional and creatively led communications alliances with the burgeoning media/communications industry. From design to advertising, from programme making to telecommunications, from regulatory bodies to multimedia companies, the paper demonstrates how the formation of the media/communications industry is at a critical stage of its life cycle having witnessed an almost meteoric proliferation of skills, profiles, professional codes and competences. The paper demonstrates that with its emphasis on creative skills, its ability to amplify and legitimise social messages and values and its constitution being determined by portfolio ‘specialist’ careers the media/communications industry presents a unique opportunity for the renewal of the voluntary sector. It also argues that the professional rules of the media/communications industry, its alliances and its ethical codification still have to be defined. Further, that this definition is integral to the growth of a profession and could, if channelled effectively, underpin the repositioning of the voluntary sector for the 21st century.     

The Changing Face of Entrepreneurship in Germany

This paper explains individual start-up activities on the basis of both person-related characteristics and the regional context. The analysis is based upon micro data from the GEM adult population survey. Both individual and regional variables have an influence on the decision to become self-employed. There are considerable differences between nascent opportunity entrepreneurship and nascent necessity entrepreneurship. Whereas the results for opportunity entrepreneurship are in line with theoretical predictions the factors influencing necessity entrepreneurship are far more difficult to determine. The most significant change between 2001 and 2003/2004 is the reversal of the influence of a change in the regional rate of unemployment on nascent entrepreneurship activities.      

New technological path creation: evidence from the British and German wind energy industries

The canonical economic literature on path dependence provides only a limited explanation of why and how new technological pathways are created initially. The motivation of this paper is to address this gap in the literature and argue that evolutionary economics theories of path dependence need to be linked with sociological explanations of how new technological pathways are created in the first instance by knowledgeable inventors and innovators. These arguments are developed by the authors in a hybrid socio-economic theory of new path creation. In this paper these theoretical arguments are illustrated empirically by a comparative analysis of the introduction and diffusion of new wind power technologies in Britain and Germany. The empirical analysis focuses on the key research question of why the introduction of these new technologies started earlier and has diffused sooner in Germany than in Britain.     

Hattendorff's Theorem: A Markov chain and counting process approach

Abstract

The paper provides a generalization of Hattendorff's theorem to the situation where a life insurance policy is modelled as a time-inhomogeneous Markov chain with a finite state space. It is shown that the present values of the gains obtained in the different states are zero mean martingales and that gains realized in different states are uncorrelated. Moreover, variance formulas for the present values of the gains are derived, and the results are illustrated by examples relating to term and disability insurance.
