Labor Flexibility,Ownership and Firm Performance in China

Developed and developing countries alike areprivatizing or corporatizing state owned enterprises(SOEs), often citing the flexibility to hire and shedlabor as an advantage. However, there is littleempirical evidence on the extent to which thisimproves firm performance. This paper investigates thelinkage between labor flexibility, ownership and firmperformance using China as a case study. We find thatSOEs are much less able to adjust quickly to demandshocks than are other ownership forms and that thedegree of worker input into hiring and firingdecisions slows the ability of firms to adapt,negatively affecting firm performance.     

Leverage and Volatility Feedback Effects in High-Frequency Data

We examine the relationship between volatility and past andfuture returns using high-frequency aggregate equity index data.Consistent with a prolonged "leverage" effect, we find the correlationsbetween absolute high-frequency returns and current and pasthigh-frequency returns to be significantly negative for severaldays, whereas the reverse cross-correlations are generally negligible.We also find that high-frequency data may be used in more accuratelyassessing volatility asymmetries over longer daily return horizons.Furthermore, our analysis of several popular continuous-timestochastic volatility models clearly points to the importanceof allowing for multiple latent volatility factors for satisfactorilydescribing the observed volatility asymmetries.     

Effects of structural,relational and cognitive social capital on resource acquisition: a study of entrepreneurs residing in multiply deprived areas

ABSTRACT

Emerging research demonstrates that structural social capital facilitates the resource acquisition of entrepreneurs residing in multiply deprived areas. However, their usage of relational and cognitive social capital that translates to accessible resources is not well understood. We contribute to knowledge and comprehensively examine effects of structural, relational and cognitive social capital taken together on the resource acquisition of entrepreneurs residing in multiply deprived areas. Results from a national survey of entrepreneurs residing in multiply deprived areas across England show that large networks, bonding ties, trust, reciprocity, obligations and expectations, and shared language and codes facilitate their resource acquisition. Also, we demonstrate that they are reluctant or unable to bridge social distance and adopt narrative storytelling. Furthermore, the results indicate that entrepreneurs residing in multiply deprived areas in the most deprived regions suffer from less resource acquisition.

Are better governed funds better monitors?

Using Morningstar mutual fund stewardship grade data, we find that the governance mechanisms of mutual funds play a key role in their monitoring of portfolio firms and in their investment decisions. Mutual funds with better governance practices tend to vote responsibly on corporate governance proposals of their portfolio firms and also provide better return performance. Furthermore, these funds tend to avoid investing in poorly governed firms. The results suggest that funds with quality governance are more likely to act in the interest of their investors, and that costs associated with funds' monitoring of their portfolio firms do not adversely affect their return performance.     

Eine Bewertung der Regelenergievermarktung im Power-to-Gas-Konzept

The integration of the increasing share of fluctuating renewable energy sources into the energy system requires more options in flexibility. A promising attempt is the power-to-gas concept (PtG) which allows the production of hydrogen and synthetic natural gas (SNG) from electricity and the storage in caverns or existing gas storage facilities. However, an economic operation in Germany is not expected before 2030, when the amount of surplus energy, mainly generated in wind parks, will be sufficient. Currently, a hardly analyzed aspect is the potential commercialization of the flexible electrolysis as controllable load on the electricity balancing market. This offers opportunities to generate additional revenues and to obtain cheap electricity in the form of balancing energy. The present article has been designed to analyze this aspect and to examine the impact of a potential commercialization of balancing energy on the gas production costs within the PtG concept. At first, the current legal framework, the funding instruments of SNG and the differences between the notion ‘Speichergas’ and ‘Biogas’ will be outlined. An overview of the current balancing market will be given and the development of prices on the secondary balancing market will be evaluated as well as expected market trends will be presented. The following calculation of gas production costs, which result from applying an optimal proposal strategy on the secondary balancing market, is model-based and uses historical data. Three scenarios are defined and examined, and the impact of variable electricity prices is analyzed. The electricity balancing market is profitable and offers many opportunities for PtG plants. The results show a decrease of SNG production costs by up to 74 % to 46,9 €/MWh. As for the hydrogen, the production costs amount to approximately 25,8 €/MWh which equals a cost reduction of up to 81 % compared to conventional PtG plants without commercialization of balancing energy.     

Students' Perceptions of the Introduction of a Blended Learning Environment: An Exploratory Case Study

Virtual Learning Environments (VLE) provide the opportunity to deliver blended learning approaches that combine mixes of Information and Communications Technology (ICT) with various delivery methods and media. In 2008 and 2009, the University of Winchester in the UK redesigned a variety of accounting and financial management modules for presentation in a blended learning environment. An exploratory, qualitative case study investigated students' perceptions of the new approach. Through focus groups, students reported favourably on the blended learning approach and the views of students correlated with previous research, although there were some contrary findings. Focus groups raised issues concerning students' expectations, competence and engagement. Resources and institutional practices were identified as factors in students' attitudes towards blended learning. Issues about communication, student interaction and collaboration also emerged. Finally, some practical lessons from this case study are proposed.     

The Iterated Cte

Abstract

In this paper we present a method for defining a dynamic risk measure from a static risk measure, by backwards iteration. We apply the method to the conditional tail expectation (CTE) risk measure to construct a new, dynamic risk measure, the iterated CTE (ICTE). We show that the ICTE is coherent, consistent, and relevant according to the definitions of Riedel (2003), and we derive formulae for the ICTE for the case where the loss process is lognormal. Finally, we demonstrate the practical implementation of the ICTE to an equity-linked insurance contract with maturity and death benefit guarantees.     

The nature of value created by UK online grocery retailers

The UK retail environment is extremely competitive, forcing retailers to constantly develop and enhance both their offerings and their formats. Probably the most significant changes taking place are coming from not the products being sold themselves, but rather when, how and where they are being sold. For example, new technologies such as the Internet, CD‐Roms, electronic kiosks and digital television are opening up new opportunities for retailers through remote purchasing and delivery. While a number of large retailers have made heavy investments into electronic retailing, such as Arcadia, Marks & Spencer, Tesco and Sainsbury, it is uncertain how they are going to use this technology to gain competitive or market advantages. Given the media attention which technologies such as the Internet has attracted, there is the danger that businesses may adopt an unfocussed use. This report identifies and evaluates the ways in which major UK grocery retailers are using the Internet to create value for their users over and above that which is offered by bricks and mortar stores. Web sites of three grocery retailers were evaluated via preselected criteria in order to assess how they created value for their customers. Applying Holbrook’s typology of consumer value, the findings of the research suggest that each of the retailers surveyed are similar in terms of the nature of the value they have created for consumers online, these being value‐as‐convenience and value‐as excellence.
