International network extension processes to institutionally different markets: Entry nodes and processes of exporting SMEs

This article is about how SMEs reduce their liability of network outsidership in the process of establishing a network insider position in foreign business networks. By examining how SMEs establish insidership positions in institutionally different business networks, the authors contributes to the network approach to firm internationalization. From a detailed longitudinal and retrospective case study of four SMEs from mature market entering emerging country markets and four SMEs from such immature markets entering mature markets, the authors develop propositions based on intra-group and inter-group analysis. The propositions concern the parties to which the exporter initiates and develops relationships when plugging into the foreign network (the entry node), and how the firm reaches an insider position in this network (the entry process). Three distinct network types are identified along this entry process: the exposure network, the formation network and the sustenance network.     

Common socio-economic cycle periods

We present a meta-analysis of cycle periods in historical socio-economic data found in the K-wave literature. The literature on stochastic and deterministic cycles in variables such as the consumer price index, employment, interest rates, commodity prices, GDP, war and hegemony is huge and scattered. However our meta-analysis reveals various commonalities. Our key finding is that there is a common set of cycle periods that is common across most socio-economic variables.     

Probability and quantile estimation from individually micro-aggregated data

Micro-aggregation is a frequently used strategy to anonymize data before they are released to the scientific public. A sample of a continuous random variable is individually micro-aggregated by first sorting and grouping the data into groups of equal size and then replacing the values of the variable in each group by their group mean. In a similar way, data with more than one variable can be anonymized by individual micro-aggregation. Data thus distorted may still be used for statistical analysis. We show that if probabilities and quantiles are estimated in the usual way by computing relative frequencies and sample quantiles, respectively, these estimates are consistent and asymptotically normal under mild conditions.     

Model-based auditing using REA

The recent financial crisis has renewed interest in the value of the owner-ordered auditing tradition that starts from society's long-term interest rather than management interest. This tradition uses a model-based auditing approach in which control requirements are derived in a principled way. A problem with this approach is that it has been proven hard to apply it in modern complex organizations. Making it feasible requires at least an adequate enterprise modeling approach. In this paper, it is shown that the REA ontology fulfills most of the requirements for such a model-based approach. The analysis also suggests some directions in which REA can be extended.     

Social economy and employment – the case of Sweden

Recent research has shown growing shares of employment in the social economy (or non-profit sector) both in the European Union and in the United States. In the EU, there seems to be growing hopes that the social economy will be capable of contributing to local progress on the unemployment issue in crisis regions. This paper analyses employment in certain entrepreneurial forms, usually considered belonging to the social economy, in Sweden during the 1990s. The results show considerable regional differences of employment in the social economy, but also that its share of the labor market is very limited. The effect of social-economic organizations on employment, therefore, is probably mainly indirect in as much as they function as platforms for cooperation between firms or else as embryos for enterprises by strengthening local entrepreneurship and helping to nurture a deposit of social capital which has visible effects on private business and jobs. However, these effects need more detailed examinations.     

Club theory and household formation

The relationship between our general equilibrium model with multi-member households and club models with multiple private goods is investigated. The main distinction in the definitions consists in the equilibrium concepts. As a rule, competitive equilibria among households where no group of consumers can benefit from forming a new household and valuation equilibria prove equivalent in the absence of consumption externalities, but not in their presence.     

Segmenting a market in the making: Industrial market segmentation as construction

This paper takes an empirical starting point in a claim that Biacore, a pioneering Swedish producer of affinity biosensors, was “in the enviable position of creating its own market” (Abelin, 1997). An in-depth case study traces how Biacore undertook segmentation activities while shaping the market for its new product technology, affinity biosensors. This involved stabilising the modes of exchange with customers, the product and the identity of the company. The efforts of Biacore highlight a constructive dimension of market segmentation that hitherto has received little attention. Rather than a process of describing, deciding and taking action, Biacore engaged in the gradual construction of market segments through an interactive and iterative process involving close collaboration with early users. Simultaneously, the market for the new technology gained shaped. Thus, the paper reports a ‘markets from networks’ story illustrating how the practice of segmenting a market may have consequences for that market.     

Planning for balanced growth in Chinese air traffic: A case for statistical mechanics

This paper identifies drivers of variations within air traffic systems highlighting inefficient mechanisms that can lead to system sub-optimality. Domestic air traffic in China is used as a case study. Airports need to respond to local demands with airlines that control parts of the system as agents. The relationship between the agent's behavior and system-wide variations in traffic movements shows how the collective behavior of a relatively few agents can disproportionately influence the system-wide traffic distribution.     

Utility Functions

Abstract

This article is a self-contained survey of utility functions and some of their applications. Throughout the paper the theory is illustrated by three examples: exponential utility functions, power utility functions of the first kind (such as quadratic utility functions), and power utility functions of the second kind (such as the logarithmic utility function). The postulate of equivalent expected utility can be used to replace a random gain by a fixed amount and to determine a fair premium for claims to be insured, even if the insurer’s wealth without the new contract is a random variable itself. Then n companies (or economic agents) with random wealth are considered. They are interested in exchanging wealth to improve their expected utility. The family of Pareto optimal risk exchanges is characterized by the theorem of Borch. Two specific solutions are proposed. The first, believed to be new, is based on the synergy potential; this is the largest amount that can be withdrawn from the system without hurting any company in terms of expected utility. The second is the economic equilibrium originally proposed by Borch. As by-products, the option-pricing formula of Black-Scholes can be derived and the Esscher method of option pricing can be explained.
