Why Sweden's pension reform was able to be successfully implemented

Governments that do not reform pay-as-you-go (PAYG) pension systems will eventually face a pension crisis. In a democracy, reforms require majority support. The problem is that pension reform requires today's generation to bear the burden to avoid burdening tomorrow's generation. Sweden recently passed pension legislation that specifies a gradual transition from a public defined-benefit plan to a defined contribution plan. Why was Sweden successful in reforming its pension system? We find that a political economy perspective helps to answer this question: there are more winners who would vote in favour of the reform than non-winners who would vote against it. When comparing the net effect (present value of expected benefits minus present value of remaining contributions) of the new and old systems, contributions of the working generation (age < 53) are reduced by more than their expected benefits.     

Generative Mechanisms of the Adoption of Logistics Innovation: The Case of On‐site Shops in Construction Supply Chains

Empirical studies of logistics innovations have focused on the innovation process, bypassing much the innovative artifact or solution design itself. Focusing on the artifact and solution design in a case study, we contribute to the emerging theory of logistics innovations through articulating the generative mechanisms of the adoption of logistics innovation, that is, the mechanisms through which the design of the solution enables its adoption. We study On‐site Shop, a rare example from the construction industry of a logistics innovation that has successfully migrated from a limited number of pilots to common practice. The case study is based on insights from participation in the design of the solution, and on 55 interviews conducted in a relationship triad consisting of three groups: (1) construction site users, (2) the solution designers, and (3) the suppliers. We propose that standard and efficient solution set‐up is the key enabler of logistics innovation's adoption at temporary construction sites. Communication and operating rules facilitate adoption in the triad, whereas internal and external integration further advance adoption by creating links between the innovative logistics solution and other activities. Finally, trilateral collaboration and congruent technological frames in the relationship triad sustain adoption over time.     

Do Immigrants Affect Firm‐Specific Wages?*

We propose and test a novel effect of immigration on wages. Existing studies have focused on the wage effects that result from changes in the aggregate labour supply in a competitive labour market. We argue that if labour markets are not fully competitive, immigrants might also affect wage formation at the most disaggregate level – the workplace. Using linked employer?employee data, we find that an increased use of low‐skilled immigrant workers has a significantly negative effect on the wages of native workers at the workplace – also when controlling for potential endogeneity of the immigrant share using both fixed effects and instrumental variables.     

Internationalisation of Japanese professional business service firms

This paper explores the internationalisation of Japanese professional business service (PBS) firms. The UK was chosen as the geographical area of study due to the large number of Japanese foreign direct investments over the last 20 years. A comparative study of Japanese and Western service providers was conducted in the UK in spring 2002 to ascertain if there are any significant differences in their ways of doing business with Japanese clients. The preliminary results show that Japanese firms tend to be very small in the UK in terms of both size and market share. They seem also to be tightly connected with Japanese businesses operating in the UK.     

Nanobiomedical science in China: a research field on the rise

Medical and health care applications of nanotechnology have increasingly attracted research and innovation attention. Nano-biomedical science (NBMS) is a term we use to define this emerging domain. As China is one of the leading countries in nanotechnology, but lacks a long history as a biosciences leader, this paper explores the competitive positioning of China in the development of NBMS. Specifically, this paper profiles the research patterns of Chinese NBMS in comparison with the four other largest countries in NBMS, using bibliometric techniques. The results indicate that China is a leader in NBMS, leveraging its strengths in chemistry and physics in the broader nanotechnology domain. However, China's relative weakness in traditional biomedical disciplines, and its lack of presence in highly influential global journals, could prove to be limiting factors.     

Pricing Asian options in a semimartingale model

In this paper we studyy arithmetic Asian options when the underlying stock is driven by special semimartingale processes. We show that the inherently path dependent problem of pricing Asian options can be transformed into a problem without path dependence in the payoff function. We also show that the price is driven by a process with independent increments, Levy processes being a special case. This approach applies for both discretely or continuously options.
