- 2018

- We provide evidence that choices over small stakes bets are consistent with assumptions of some payoff calibration paradoxes. We then exploit the existence of detailed information on individual wealth of our experimental subjects in Denmark, and directly estimate risk attitudes and the degree of asset integration. We discover that behavior is consistent with partial, rather than full, asset integration. The implied risk attitudes from estimating these specifications indicate risk premia and certainty equivalents that are a priori plausible. This theory and evidence suggest one constructive solution to payoff calibration paradoxes.

Multiattribute Utility Theory, Intertemporal Utility, and Correlation Aversion
- 2018

- Convenient assumptions about qualitative properties of the intertemporal utility function have generated counterintuitive implications for the relationship between atemporal risk aversion and the intertemporal elasticity of substitution. If the intertemporal utility function is additively separable, then the latter two concepts are the inverse of each other. We review a theoretical specification with a long lineage in the literature on multi-attribute utility and use this theoretical structure to guide the design of a series of experiments that allow us to identify and estimate intertemporal correlation aversion. Our results show that subjects are correlation averse over lotteries with intertemporal income profiles.

Bootstrapping Error Component Models
- 2001
-
Ingår i: Computational statistics (Zeitschrift). - : Physica Verlag. - 0943-4062 .- 1613-9658. ; 16:2, s. 221-231

Tidskriftsartikel (refereegranskat)abstract
- This paper proposes several resampling algorithms suitable for error component models and evaluates them in the context of bootstrap testing. In short, all the algorithms work well and lead to tests with correct or close to correct size. There is thus little or no reason not to use the bootstrap with error component models.

Accounting for Job Growth : Disentangling Size and Age Effects in an International Cohort Comparison
- 2013
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The contribution of different-sized businesses to job creation continues to attract policymakers’ attention, however, it has recently been recognized that conclusions about size were confounded with the effect of age. We probe the role of size, controlling for age, by comparing the cohorts of firms born in 1998 over their first decade of life, using variation across half a dozen northern European countries Austria, Finland, Germany, Norway, Sweden, and the UK to pin down the effects. We find that a very small proportion of the smallest firms play a crucial role in accounting for cross-country differences in job growth.

Covisint in Europe : Analysing the B2B auto e-marketplace
- 2005
-
Ingår i: International Journal of Automotive Technology and Management. - : InderScience Publishers. - 1470-9511 .- 1741-5012. ; 5:1, s. 31-45
-
Tidskriftsartikel (refereegranskat)abstract
- Electronic marketplaces are a popular phenomenon, both for academics and for practitioners. One of the most discussed e-marketplace is Covisint, the 'big' e-marketplace of the automotive industry. This paper analyses Covisint via transaction cost economics, the tool of choice when analysing e-marketplaces in academia. The empirical material consists of interviews with operatives and managers from customers and owners of Covisint, suppliers, potential customers that have chosen not to join Covisint, and Covisint themselves. The results indicate that Covisint has several problems: lack of incentives for suppliers to join the initiative, lack of participating organisations on the supplier side and an overall lack of ability to balance interests and objectives of the actors involved.

E-procurement maturity in industry
- 2003
-
Ingår i: International Journal of Electronic Business. - : InderScience Publishers. - 1470-6067 .- 1741-5063. ; 1:4, s. 396-407
-
Tidskriftsartikel (refereegranskat)abstract
- This paper aims to examine the use and implementation of electronic procurement for indirect material in eight large global companies, and investigate what kinds of barriers exist towards electronic procurement. The empirical evidence comes from interviews with e-procurement experts and operatives in eight global firms. Results show that three out of eight companies are using e-procurement and four are planning to do so in the future. Barriers shown by the empirical material are lack of technological standard, different IT-maturity among suppliers, resistance among users to leaving old suppliers, lack of support from top management, differences in language, culture and legal systems. Other barriers found are getting suppliers to update and control the electronic product catalogues and to monitor them and getting the users in the organisation to use the system.

Individual information system acceptance behaviour : An electronic ordering system case
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Organizations have spent and continue to spend millions of dollars on information systems (IS) in order to enable business success. Information systems have long been used to help managers make better decisions, better understand the nature of customers and improve employee productivity. They have enabled transformations in organizations, such as simplification and acceleration of work processes, and contributed to continued improvement and innovation in these processes. It is not that easy however to make this simplification and acceleration of work processes to happen. A common problem is that individuals that are supposed to use these systems do not use them, and if an information systems is to contribute to business success it has to be adopted and used. The question is therefore, how do we get individuals to adopt and use systems that are implemented?This dissertation focus on what influences individual adoption and use, and how we can get individuals to adopt and use systems that are implemented. The information system under investigation is an electronic ordering (e-ordering) system. E-ordering systems are used by individual end-users (requestors, authorizers and goods receivers) in an organization when ordering products and services. The system aims at contributing to reduced maverick (i.e. wild= purchases and increased compliance with a few centrally chosen suppliers, thus facilitating lower purchasing prices and a reduction of the costs for purchasing. The thesis also discusses the relative difficulty in getting individuals to continue to use the systems compared to get them to adopt it. Another issue that is discussed is that the acceptance process does not have to happen gradually, it can instead happen in short spurts. It is further discussed what can influence these spurts.

The road towards successful e-ordering implementation : Success factors and barriers
- 2008
-
Ingår i: International Journal of procurement management. - : InderScience Publishers. - 1753-8432 .- 1753-8440. ; 1:4, s. 415-429
-
Tidskriftsartikel (refereegranskat)abstract
- Implementing an e-ordering system in a successful way, i.e., managing the implementation process, overcoming the barriers that occur and achieving a satisfactory compliance rate, is not as easy as some consultants and software companies claim. Understanding how a given organisation has managed the implementation process (resulting in a satisfactory compliance rate) may help other organisations achieve the successful implementation of e-ordering systems. The present paper describes the implementation of an e-ordering system in a large pharmaceutical organisation, discussing the problems it faced and how those were overcome. An analysis of the success factors found in previous research is presented, revealing one area that influences implementation success to a larger extent: the end user uptake. A four-year longitudinal case study is presented, which is based on interviews, observations made in daily work, at meetings and training sessions, and other documentation.

The structure of determinants of individual adoption and use of e-ordering systems
- 2008
-
Ingår i: Human Systems Management. - : IOS Press. - 0167-2533 .- 1875-8703. ; 27:2, s. 143-159
-
Tidskriftsartikel (refereegranskat)abstract
- Electronic ordering (e-ordering) systems are currently being implemented in both private and public organizations. The advantages of these systems are widely acknowledged: increased compliance with use of fewer suppliers and improved efficiency. However, realizing these benefits is difficult due to end-user resistance to adopting and using such systems. The present paper proposes a framework inspired by adaptive structuration theory (AST) that functions as an analytical framework that helps to understand what structures and factors influence adoption and use of an e-ordering system. To the adapted AST framework is added factors of influence found in previous purchasing research, resulting in a framework that helps to understand adoption and use of an e-ordering system over time. The framework is tested using empirical data from a 4-year longitudinal case study. The paper embeds purchasing theory within the structuration framework of AST.

A note on employment and gross domestic product in Swedish family-owned businesses : a descriptive analysis
- 2011
-
Ingår i: Family Business Review. - San Francisco : Family Firm Institute. - 0894-4865 .- 1741-6248. ; 24:4, s. 362-371
-
Tidskriftsartikel (refereegranskat)abstract
- The Swedish government gathers information that helps identify family-owned businesses and enabled us to analyze every business in the economy over a longer period than has heretofore been reported. Using these data, we found that family-owned businesses account for up to one fourth of total employment and one fifth of GDP in Sweden. These shares have increased over time, due in part, to economic policy. We compare our findings with other studies and suggest how Sweden and other governments might make family firm data more readily available for researchers.
