Social Capital and its Influence on Changes in Internationalization Mode among Small and Medium-Sized Enterprises:

Abstract: This article explores how social capital influences a firm to change its internationalization mode. The authors use an in-depth qualitative study to identify 36 internationalization mode changes in ten New Zealand and ten Swedish small and medium-sized enterprises. This article contributes to the internationalization mode literature by focusing on relationships and mode change. Using the network approach, the authors develop three categories of social capital and discuss their role in influencing mode change. The roles include the efficacy role, the serendipity role, and the liability role of social capital. These three roles incorporate both the positive and the negative aspects of social capital. The liability role is the most frequently observed form of social capital to influence mode change. The most frequent type of mode change is toward a high-control internationalization mode.

The sustainable development oxymoron: quantifying and modelling the incompatibility of sustainable development goals

Abstract: In 2015, the UN adopted a new set of Sustainable Development Goals (SDGs) to eradicate poverty, establish socioeconomic inclusion and protect the environment. Critical voices such as the International Council for Science (ICSU), however, have expressed concerns about the potential incompatibility of the SDGs, specifically the incompatibility of socio-economic development and environmental sustainability. In this paper, we test, quantify and model the alleged inconsistency of SDGs. Our analyses show which SDGs are consistent and which are conflicting. We measure the extent of inconsistency and conclude that the SDG agenda will fail as a whole if we continue with business as usual. We further explore the nature of the inconsistencies using dynamical systems models, which reveal that the focus on economic growth and consumption as a means for development underlies the inconsistency. Our models also show that there are factors which can contribute to development (health programmes, government investme...

Social relations and cooperation in organizations

Abstract: This paper addresses the effects of social relations on cooperation (or collusion) in organizations (or communities). Social and production relations are modeled as separate repeated strategic interactions. “Linking” them – by employing members of the same community or encouraging social interaction between employees – facilitates cooperation in production: (a) because of available “social capital,” the slack of enforcement power present in social relations which may discipline behavior in the workplace; (b) because payoffs from the two relations are substitutes, therefore the linkage endogenously generates social capital; (c) because the linkage generates transfers of “trust”; and (d) it discloses information about agents' situation.

Assessing the effect of public policy on worker absenteeism

Abstract: We analyze the effect of economic incentives on worker absenteeism, using panel data on work absence for 1990 and 1991 with a sample of 1,396 Swedish blue-collar workers. During this period Sweden implemented major reforms of both its national income replacement program for short-term sickness and income taxes. Both affected the worker's cost of missing work. Our econometric model allows for state-dependent dynamic behavior and control for unobserved heterogeneity. The latter proves to be an important consideration. We find that the cost of being absent significantly affects work absence behavior.

A note on Wick products and the fractional Black-Scholes model

Abstract: In some recent papers (Elliott and van der Hoek 2003; Hu and Oksendal 2003) a fractional Black-Scholes model has been proposed as an improvement of the classical Black-Scholes model (see also Benth 2003; Biagini et al. 2002; Biagini and Oksendal 2004). Common to these fractional Black-Scholes models is that the driving Brownian motion is replaced by a fractional Brownian motion and that the Ito integral is replaced by the Wick integral, and proofs have been presented that these fractional Black-Scholes models are free of arbitrage. These results on absence of arbitrage complelety contradict a number of earlier results in the literature which prove that the fractional Black-Scholes model (and related models) will in fact admit arbitrage. The objective of the present paper is to resolve this contradiction by pointing out that the definition of the self-financing trading strategies and/or the definition of the value of a portfolio used in the above papers does not have a reasonable economic interpretation, and thus that the results in these papers are not economically meaningful. In particular we show that in the framework of Elliott and van der Hoek 2003, a naive buy-and-hold strategy does not in general qualify as “self-financing”. We also show that in Hu and Oksendal 2003, a portfolio consisting of a positive number of shares of a stock with a positive price may, with positive probability, have a negative “value”.
