Business model innovation: Identifying foundations and trajectories

Business model innovation is an emerging hot topic in management research. It has been developing steadily for 20 years and has gained enormous momentum in recent years. A solid basis has been created, and the first literature reviews summarize the topic. However, an analysis of the core literature and the general foundation of business model innovation literature is missing. This gap is closed with this bibliometric. It analyzes 30 core articles referenced in 380 business model innovation publications. From this, a total of four research clusters can be delineated. This foundation of the research area is supplemented with a trend analysis of recent publications, which identifies three trends for the future of this research stream. The analysis highlights that sustainability, dynamic capabilities, and small- and medium-sized enterprises are the most promising trends in business model innovation. Based on the results, we present a general model for business model innovation.     

Time-varying beta risk of Pan-European industry portfolios: A comparison of alternative modeling techniques

This paper investigates the time-varying behavior of systematic risk for 18 pan-European sectors. Using weekly data over the period 1987–2005, six different modeling techniques in addition to the standard constant coefficient model are employed: a bivariate t-GARCH(1,1) model, two Kalman filter (KF)-based approaches, a bivariate stochastic volatility model estimated via the efficient Monte Carlo likelihood technique as well as two Markov switching models. A comparison of ex-ante forecast performances of the different models indicate that the random walk process in connection with the KF is the preferred model to describe and forecast the time-varying behavior of sector betas in a European context.     

The role of entrepreneurial orientation in service firms: empirical evidence from Austria

Entrepreneurial behaviour is becoming increasingly important for all firms, regardless of size, age, or industry sector. It is increasingly seen as one of the most important drivers for economic growth and corporate success. Nevertheless, no empirical research has so far concentrated on the role of entrepreneurial behaviour in service firms, although the service sector has become the most important (and the only growing) industry sector. This article therefore investigates the relationship between entrepreneurial orientation (EO) and corporate performance on the basis of an empirical survey of 310 service firms in Austria. Here, a significant positive relationship between EO and corporate performance could be identified, with a clear emphasis on innovative behaviour as the most important sub-dimension.     

The nucleolus of large majority games

Members of a shareholder meeting or legislative committee have greater or smaller voting power than meets the eye if the nucleolus of the induced majority game differs from the voting weight distribution. We establish a new sufficient condition for the weight and power distributions to be equal, and we characterize the limit behavior of the nucleolus in case all relative weights become small.     

Oil Price Formation: Measuring Economic and Political Factors

In this article the different factors which influence the oil price are introduced and tested for their influence on two crudes, namely Arab Light and Bonny Light, a Saudi Arabian and a Nigerian crude respectively in the time period between 1990 and 2004. It is argued that in accordance with Efficient Market Hypothesis the decisions made by investors on different oil markets are incorporating publically available information into prices. This information is represented by events, with a focus on international political events, but also OPEC-decisions, development of the US-Dollar, and catastrophes. The analysis is accomplished by using the method of Time Series Analysis. This tool allows for testing the influence on the mean as well as the variance of oil price returns. The results show a startlingly low influence of OPEC-decisions, a strong influence of the US-Dollar, a strong influence of catastrophes in oil-producing countries on the volatility, a relationship between the location where a political event takes place and its impact on crude oil returns, as well as a rising influence of terrorism on oil.     

Global retail lending in the aftermath of the US financial crisis: Distinguishing between supply and demand effects

This paper examines the broader effects of the US financial crisis on global lending to retail customers. In particular we examine retail bank lending in Germany using a unique data set of German savings banks during the period 2006 through 2008 for which we have the universe of loan applications and loans granted. Our experimental setting allows us to distinguish between savings banks affected by the US financial crisis through their holdings in Landesbanken with substantial subprime exposure and unaffected savings banks. The data enable us to distinguish between demand and supply side effects of bank lending and find that the US financial crisis induced a contraction in the supply of retail lending in Germany. While demand for loans goes down, it is not substantially different for the affected and nonaffected banks. More important, we find evidence of a significant supply side effect in that the affected banks reject substantially more loan applications than nonaffected banks. This result is particularly strong for smaller and more liquidity-constrained banks as well as for mortgage as compared with consumer loans. We also find that bank-depositor relationships help mitigate these supply side effects.     

Residual affective commitment to organizations: Concept,causes and consequences

Research on affective organizational commitment has largely been conceptually restricted by the temporal boundaries of organizational membership, while only few authors have addressed how individuals may commit to an organization before becoming members. Given that individual careers increasingly span across a greater number of organizations, this restriction limits our ability to capture how employees experience their workplaces throughout their careers. Addressing this gap, this article contributes to the literature on affective commitment by arguing that individuals may remain affectively committed to an organization after having left it. We extend the temporal structure of affective commitment beyond separation by introducing the concept of residual affective commitment, and present a model of how such commitment is formed. We elucidate the interplay between residual and current affective commitment, complementing research on organizational newcomers. Finally, we open up new avenues for research by discussing theoretical consequences of the introduction of residual commitment.     

Creating Backward Linkages from Multinationals: Is there a Role for Financial Incentives?

We investigate whether government subsidies encourage foreign multinationals to create linkages with domestic suppliers. To this end we use a unique panel dataset of foreign multinationals located in Ireland for which we have exhaustive information on grant receipt. Our results indicate that while European and US foreign plants develop backward linkages independently of grant receipt, multinationals from other parts of the world respond positively to government support. Our results hold even when controlling for the possible endogeneity of grants and the boundedness of the linkage variable. We conclude that governments should not apply a “one‐size‐fits‐all” approach to incentivizing foreign multinationals.
