Telecom reforms in the EU: Prices and consumers' satisfaction

The paper shows the impact of privatization and liberalization on consumers in the telecommunication sector for 15 EU countries. Policy reforms are summarized by the OECD regulatory indicators (REGREF) that consider the extent of privatization, vertical disintegration, and market entry. After controlling for other country variables, first, a test of the impact of ownership and regulatory changes on consumer prices is given. In the second step, the Eurobarometer data on consumers' satisfaction about quality and prices of the telecommunication service are considered. The analysis confirms the importance of market regulation in reducing prices but minimizes the role played by privatization per se. Overall, the findings offer only mixed evidence, and somehow contradict, the hypothesis that all the reforms work in a similar way across the EU countries.     

Start-ups by the unemployed: characteristics,survival and direct employment effects

Fostering and supporting start-up businesses by unemployed persons has become an increasingly important issue in many European countries. These new ventures are being subsidized by various governmental programs. Empirical evidence on skill-composition, direct job creation and other key variables is rather scarce, largely because of inadequate data availability. We base our analysis on unique survey data containing a representative sample of over 3,100 start-ups founded by unemployed persons in Germany and subsidized under two different schemes: the bridging allowance (BA) and the start-up-subsidy (SUS). We are able to draw on extensive pre- and post-founding information concerning the characteristics of the business (start-up capital, industry, etc.) and of the business founders (education, motivation, preparation, etc.). Our main results are: (1) The two programs attracted very different business founders (higher skilled for the BA, more female persons for the SUS), and different businesses were created (less capital intensive for the SUS). (2) We find that formerly unemployed founders are motivated by push and pull factors. (3) Survival rates 2.5 years after business founding are quite high (around 70%) and similar for both programs and across gender. (4) However, the newly developed businesses differ significantly in terms of direct employment effects. While around 30% of the founders with the BA already have at least one employee, this is true for roughly 12% of the founders with the SUS.     

Will It Spread or Not? The Effects of Social Influences and Network Topology on Innovation Diffusion

Innovation diffusion theory suggests that consumers differ concerning the number of contacts they have and the degree and the direction to which social influences determine their choice to adopt. To test the impacts of these factors on innovation diffusion, in particular the occurrence of hits and flops, a new agent‐based model for innovation diffusion is introduced. This model departs from existing percolation models by using more realistic agents (both individual preferences and social influence) and more realistic networks (scale free with cost constraints). Furthermore, it allows consumers to weight the links they have, and it allows links to be directional. In this way this agent‐based model tests the effect of VIPs who can have a relatively large impact on many consumers. Results indicate that markets with high social influence are more uncertain concerning the final success of the innovation and that it is more difficult for the innovation to take off. As consumers affect each other to adopt or not at the beginning of the diffusion, the new product has more difficulties to reach the critical mass that is necessary for the product to take off. In addition, results of the simulation experiments show under which conditions highly connected agents (VIPs) determine the final diffusion of the innovation. Although hubs are present in almost any network of consumers, their roles and their effects in different markets can be very different. Using a scale‐free network with a cut‐off parameter for the maximum number of connections a hub can have, the simulation results show that when hubs have limits to the maximum number of connections the innovation diffusion is severely hampered, and it becomes much more uncertain. However, it is found that the effect of VIPs on the diffusion curve is often overestimated. In fact when the influence of VIPs on the decision making of the consumers is strengthened compared with the influence of normal friends, the diffusion of the innovation is not substantially facilitated. It can be concluded that the importance of VIPs resides in their capacity to inform many consumers and not in a stronger persuasive power.     

Has the Internet Eliminated Regional Price Differences? Evidence from the Used Car Market

We study the effects of the Internet on regional price differences. Comparing two Dutch regions, we find that before the rise of the Internet, price differences of used cars between those regions amounted to some 11–15%, controlling for mileage, age, fuel type and engine volume. These price differences have completely disappeared after the rise of the Internet, in particular a website that allows consumers to make detailed comparisons between almost all used cars for sale in the Netherlands.     

New development: The crisis and European local government reforms

This article highlights the main reform trajectories put in place in French, Italian, German and Portuguese local governments during the recent crisis and identifies a number of important trends: for example increasing centralization of decision-making powers away from local governments. The authors explain why local governments have an opportunity to use reforms during the crisis to strategically reposition their value proposition.     

Computer-Mediated Customization Tendency (CMCT) and the Adaptive e-Service Experience

Adaptive customization systems are common in the delivery of e-service. However, consumers vary in their reaction to these systems. We introduce computer-mediated customization tendency (CMCT), a composite individual difference variable that reflects a consumer's personal preferences for designing and interacting with adaptive online environments to create valuable e-service experiences. To measure CMCT, we developed a formative index composed of need for control, technology innovativeness, and aesthetic appreciation. The results show CMCT influences adaptive online behavior and the perceived value of the adaptive e-service experience. In addition, customization-prone and customization-averse consumers differ in how they perceive the costs, benefits, and overall value of the experience.     

DO PERCEPTIONS BECOME REALITY? THE MODERATING ROLE OF SUPPLY CHAIN RESILIENCY ON DISRUPTION OCCURRENCE

The concern and study of supply risk and supply continuity has recently come to the forefront in managing business and conducting research. This empirical study of U.S. and German firms investigates the relationship between perceived supply risk sources and supply disruption occurrence, as well as the use of supply chain resiliency practices to reduce disruption frequency. We demonstrate that supply managers' concerns with risk emanating from suppliers and the supply market are positively related to supply disruption occurrence. We further show how and when implementing flexibility and redundancy may reduce the effects of supply disruptions.     

INDIFFERENCE PRICE WITH GENERAL SEMIMARTINGALES

Using duality methods, we prove several key properties of the indifference price π for contingent claims. The underlying market model is very general and the mathematical formulation is based on a duality naturally induced by the problem. In particular, the indifference price π turns out to be a convex risk measure on the Orlicz space induced by the utility function.
