To converge or not converge: unit labor cost inflation in the Euro area

In this article, convergence of unit labor cost (ULC) inflation within the Euro area is tested by means of panel unit root tests. To account for the small cross-sectional dimension, cross-sectional dependence of model innovations and time varying volatility, wild bootstrap critical values are employed for inference. Convergence is tested separately for pre- and post-Euro introduction subperiods. Moreover, we identify particular economies that are characterized by diverging ULC inflation after the introduction of the Euro. While the German economy is characterized by ULC inflation which is persistently below the sample average, Spain and Italy have suffered sustained losses of price competitiveness against their trading partners within the Euro area. ULC inflation in Finland, France, and Ireland can be classified as neutral with respect to relative competitive positions.     

Start-ups, long- and short-term survivors, and their contribution to employment growth

This study documents that the survival of start-ups is central in explaining the relationship between entry and regional employment growth. Distinguishing between start-ups according to the period of their survival shows that the positive effect of new business formation on employment growth is mainly driven by those new businesses that are strong enough to remain in the market for a certain period of time. This result is especially pronounced for the relationship between the surviving start-ups and employment growth in incumbent businesses indicating that there are significantly positive indirect effects of new business formation on regional development. We draw conclusions for policy and make suggestions for further research.     

Information acquisition in conflicts

This paper considers incentives for information acquisition ahead of conflicts. First, we characterize the (unique) equilibrium of the all-pay auction between two players with one-sided asymmetric information where one player has private information about his valuation. Then, we use our results to study information acquisition prior to an all-pay auction. If the decision to acquire information is observable, but not the information received, one-sided asymmetric information can occur endogenously in equilibrium. Moreover, the cut-off values of the cost of information that determine equilibrium information acquisition are higher than those in the first best. Thus, information acquisition is excessive. In contrast, with open or covert information acquisition, the equilibrium cut-off values are as in the first best.     

Who will lead and who will follow: Identifying Influential Users in Online Social Networks

Along with the explosive growth of the phenomenon Online Social Networks (OSN), identifying influential users in OSN has received a great deal of attention in recent years. However, the development of practical approaches for identifying them is still in its infancy. By means of a structured literature review, the authors analyze and synthesize the publications particularly from two perspectives. From a research perspective, they find that existing approaches mostly build on users’ connectivity and activity but hardly consider further characteristics of influential users. Moreover, they outline two major research streams. It becomes apparent that most marketing-oriented articles draw on real-world data of OSN, while more technology-oriented papers rather have a theoretical approach and mostly evaluate their artifacts by means of formal proofs. The authors find that a stronger collaboration between the scientific Business and Information Systems Engineering (BISE) and Marketing communities could be mutually beneficial. With respect to a practitioner’s perspective, they compile advice on the practical application of approaches for the identification of influential users. It is hoped that the results can stimulate and guide future research.     

Trade creation and the status of FTAs: empirical evidence from East Asia

East Asia has been considered a latecomer with respect to Free Trade Agreements (FTAs). Since the turn of the last century, however, FTAs with East Asian participation have seen an intra- and extra-regional expansion. Many trade initiatives have been proposed, negotiated or even implemented. This introduces interesting perspectives for the analysis of trade agreements regarding their anticipatory trade effects. This paper focuses on the trade impact of FTAs at different stages that East Asian economies participate in. The central part of this study is an econometric analysis that applies panel data to the gravity model of international trade flows. We augment the traditional model with variables to estimate trade effects of bilateral and multilateral agreements and year-to-year changes in the stages of their implementation. Our results reveal that there exist anticipatory effects preceding the actual implementation of bilateral FTAs with East Asian participation. Further, anticipation effects are larger for bilateral than for multilateral agreements, possibly because the realisation of bilateral agreements is considered more realistic.     

Evolutionary stability of discrimination under observability

We study the evolution of preferences under perfect and almost perfect observability in symmetric 2-player games. We demonstrate that if nature can choose from a sufficiently general preference space, which includes preferences over outcomes that may depend on the opponent's preference-type, then, in most games, only discriminating preferences (treating different types of opponents differently in the same situation) can be evolutionary stable and some discriminating types are stable in a very strong sense in all games. We use these discriminating types to show that any symmetric outcome which gives players more than their minmax value in material payoffs (fitness) can be seen as equilibrium play of a player population with such strongly stable preferences.     

Cross-cultural entrepreneurship research: Current status and framework for future studies

Although cross-cultural research in the field of entrepreneurship is still in its infancy as a research stream, it offers important inferences for both theory and practice. Some have criticized the relative immaturity of previous survey-based studies’ methodology. In order to address this flaw, we analyze existing survey-based studies in the field of cross-cultural entrepreneurship to identify research gaps in content and methodology and then derive the most appropriate analytical approach to fill the gaps for this type of research. Finally, we present a practical framework in which to conduct sound and prudent future studies, integrating the most appropriate analytical approach, general methodological insights, and the particularities of entrepreneurship research in a cross-cultural setting.

Connected and autonomous vehicle injury loss events: Potential risk and actuarial considerations for primary insurers

The introduction of connected and autonomous vehicles (CAVs) to the road transport ecosystem will change the manner of collisions. CAVs are expected to optimize the safety of road users and the wider environment, while alleviating traffic congestion and maximizing occupant comfort. The net result is a reduction in the frequency of motor vehicle collisions, and a reduction in the number of injuries currently seen as “preventable.” A changing risk ecosystem will introduce new challenges and opportunities for primary insurers. Prior studies have highlighted the economic benefit provided by reductions in the frequency of hazardous events. This economic benefit, however, will be offset by the economic detriment incurred by emerging risks and the increased scrutiny placed on existing risks. We posit four plausible scenarios detailing how an introduction of these technologies could result in a larger relative rate of injury claims currently characterized as tail‐risk events. In such a scenario, the culmination of these losses will present as a second “hump” in actuarial loss models. We discuss how CAV risk factors and traffic dynamics may combine to make a second “hump” a plausible reality, and discuss a number of opportunities that may arise for primary insurers from a changing road environment.     

Cybercrime and cloud computing. A game theoretic network model

In this paper, a network model is developed in which three players—a profit‐maximizing provider of cloud computing services, its consumers, and a hacker—sequentially choose their strategies. Several scenarios with different levels of data security and public prosecution of the hacker are analyzed. Especially for the case when no security measurements are available, a firm's strategy to limit the network size in order to render hacking unattractive is discussed in detail. Finally, policy implications are given implying better international cooperation of the law enforcement authorities.     

Endogeneity and the Dynamics of Voluntary Disclosure Quality: Is there Really an Effect on the Cost of Equity Capital?*

Research on the effects of voluntary disclosure quality on the cost of equity capital is often plagued by endogeneity concerns. In this paper, I use a dynamic panel system GMM estimator, which provides internal instruments from the firm's history that directly address endogeneity arising from unobserved heterogeneity and simultaneity. By using hand-collected voluntary disclosure scores for firms listed in the Swiss stock exchange, I examine the dynamic relation between voluntary disclosure quality and the cost of equity capital in a panel over a period of 10 years. The results suggest that the relation between voluntary disclosure quality and the cost of equity capital becomes insignificant after controlling adequately for potential dynamic endogeneity, simultaneity, and unobserved heterogeneity.
