Die Förderung der erneuerbaren Energien nach der EEG-Reform 2014

After fierce public and political debates, an amendment to Germany’s Renewable Energy Sources Act took effect on 1 August. This article provides an assessment of the revisions made: What is the impact of the amendment on the future progress of the German energy transition? Does it provide for a significant reduction and fairer distribution of the costs associated with support for renewables? Does it appropriately address the fundamental challenges associated with the market and system integration of renewable energy sources?     

EXPANDING EXTRACTIONS

In this paper, we generalize hypothetical extraction techniques. We suggest that the effect of certain economic phenomena can be measured by removing them from an input–output (I–O) table and by rebalancing the set of I–O accounts. The difference between the two sets of accounts yields the phenomenon's effect (or importance). We suggest that the approach can be used to measure the effect of changes in intermediate output, which are otherwise not easily rationalized within a Leontief framework. Of course, it can also be used to estimate the possible effects of the shutdown of a particular establishment or other identifiable segment of an economy. We demonstrate some properties and potential of the approach using the annual 2006 US I–O accounts.     

Human Capital,Gender and Organisation in Transition Agriculture: Measuring and Explaining the Technical Efficiency of Bulgarian and Hungarian Farms

Based on survey data on Bulgarian and Hungarian crop and dairy farms, a double-peaked distribution of technical efficiency is observed. Several factors explain differences in efficiency. Human capital matters not only through age and education but also through gender, as farms with a higher proportion of women are more efficient. Contracting with upstream processors increases efficiency through facilitating the adoption of technology and access to credits. The superiority of family farms over corporate farms is confirmed for crops but not for dairy produce.     

The (un)importance of the closure of village shops to rural migration patterns

This study investigates the importance of local service provision for the survival of rural areas. EU Rural Development Policy includes support to village shops as a means to sustain population. Shop closing is assumed to negatively affect migration to and from the area served. We analyse quantitative data on all Swedish village shops and the migration patterns in their market areas before and after shop closure. No significant effect of shop closure on either in- or out-migration can be established, regardless of whether larger or smaller market areas are employed or whether migrants with more urban shopping habits (i.e. commuters and families with children) are excluded. Complementary interviews in three villages where the last shop has closed verify the results.     

The Effect of Feedback on Process and Outcome of Loan Negotiations: Consequences on Risk Aversion and the Willingness to Compromise

We examined the influence of feedback regarding alternatives on risk aversion and willingness to compromise in student loan negotiations. In a simulated negotiation, participants in the roles of bank advisors and clients received feedback about alternative offers either only after an impasse of the negotiation, or regardless of outcome. When receiving feedback only after an impasse, participants tried to avoid the regret-eliciting feedback and therefore set less ambitious goals and showed higher willingness to compromise. In particular, they set a less ambitious reservation price and estimated a less beneficial ‘best alternative to negotiated agreement’. When analyzing the process of the negotiation, we found that they made less favorable offers more quickly and arrived at less favorable final offers. They sacrificed their previously set goals by violating their reservation prices and underbidding their estimated ‘best alternative to negotiated agreement’ more often. Therefore, they showed a higher potential for agreement with the other party, but at the cost of less favorable outcomes. Results indicate that anticipated regret could contribute to suboptimal negotiation outcomes in the context of student loans, which might lead to long term dissatisfaction.     

Stylised facts of financial time series and hidden Markov models in continuous time

Hidden Markov models are often applied in quantitative finance to capture the stylised facts of financial returns. They are usually discrete-time models and the number of states rarely exceeds two because of the quadratic increase in the number of parameters with the number of states. This paper presents an extension to continuous time where it is possible to increase the number of states with a linear rather than quadratic growth in the number of parameters. The possibility of increasing the number of states leads to a better fit to both the distributional and temporal properties of daily returns.     

Analysis of fixed broadband access and use in Thailand: Drivers and barriers

The aim of this paper is to analyze the demand for fixed broadband in Thailand. Data were obtained from a national survey in 2010 by the National Broadcasting and Telecommunications Commission (NBTC) of Thailand. The bivariate probit model was employed to examine empirically whether accessibility to fixed telephony infrastructure, socio-economic variables and the area of residence have a systematic link to fixed broadband access in the first stage, and then, specific usage, provided access exists, is estimated. Results of this study show that the variables, together with their potential impact, are as follows: fixed infrastructure, income, gender, level of education, age of consumer and residential area. The impact of these factors varies from service to service (i.e. video download, social network, searching and e-mail). The implications for the NBTC are to encourage competition through the infrastructure and to permit more competition in infrastructure development. This could stimulate the growth of fixed broadband access and use. At the same time, the government could also implement policies to encourage more access and usage, for example income subsidization and training program.     

The global permutations of the Western publication regime

This article introduces the concept of the ‘publication regime’ into the current discourse on academia. This allows for a much deeper understanding of how publishing conglomerates and appointment and promotion procedures in Western universities are increasingly interlocked. It then turns to the global permutations of that regime as it is currently disseminated to other parts of the world. Using empirical examples drawn primarily from the field of tourism studies, we examine the problems engendered by the introduction of the regime’s appointment and promotion procedures of early career academic staff in universities in the emerging world regions. We specify the auxiliary mechanisms intended to ameliorate these problems, and draw attention to the neo-colonial implications of the disciplining process which these mechanisms are introducing into the academic life of the universities in the emerging regions. We argue that, as the Western publication regime is becoming increasingly globalized, local intellectual voices tend to be silenced by the regime’s growing hegemony, and call for the integration of non-Western perspectives into the framework of the publication regime.     

Structural ambidexterity,transition processes,and integration trade‐offs: a longitudinal study of failed exploration

In order to overcome the exploration–exploitation paradox, structural ambidexterity literature suggests establishing differentiated units for exploitation and exploration with a carefully managed exploration–exploitation interface supporting cross‐fertilization without cross‐contamination. Recent research demonstrates the crucial role of integration mechanisms (i.e. how knowledge exchange between exploratory and exploitative units can be organized) and related transition modes (i.e. how exploratory innovations can ultimately be transferred back into the exploitative structures of core business) to deal with this challenge. However, a systematic account of the diverse tensions, risks, and trade‐offs associated with integration which may ultimately cause exploration failure is missing, so far. This paper presents a longitudinal process study uncovering the anatomy of an unsuccessful exploration of (green) technologies by a medium‐sized entrepreneurial firm. We investigated their transition processes to understand how the managers dynamically configured and reconfigured the exploration–exploitation interface over time. Our theoretical contribution lies in providing a framework of six integration trade‐offs (Exploratory‐complementary linking vs. contamination; Seeking legitimacy early on vs. frustration at discontinuation of innovation; Boundary spanning through job rotation vs. carrying over of old culture; Early vs. premature transfer; Reorganization vs. capability mutation; and Improved access to core business resources vs. resource starvation) linked to three phases in the transition process (before, at, and after transfer). We also highlight mechanism, pulling‐forward, and streamlining‐related failures linked to integration trade‐offs in resource‐constrained contexts. Our implication for R&D and top management is that the use of integration mechanisms for structural ambidexterity bears the risk of cross‐contamination between the exploitative and exploratory structures and are therefore inevitably linked to trade‐offs. To minimize negative side effects and prevent exploration failure, organizations have to consciously select, schedule, operationalize, and manage (re)integration mechanisms along the transition process. Our framework of integration trade‐offs systematically supports managers in their organizational design choices for integration mechanisms in the transition processes.     

Horizontal integration in the Dutch financial sector

In this paper, the consequences of cross-shareholding in an n-firm industry are analyzed. Our attention focuses on the case where firms have silent interests in each other. These interests can be direct or indirect. We analyze the effects of cross-shareholding on the price–cost margins in a Cournot and a Bertrand setting. In all cases, competition is reduced due to shareholding interlocks. As an empirical example the Dutch financial sector is used. Comparing the case of shareholding with the case of no-shareholding, the price–cost margins are found to be up to 2% higher in a Bertrand market, and at least 8% higher in a Cournot market.
