The proposed method of Stochastic Non-smooth Envelopment of Data (StoNED) for measuring efficiency has to date mainly found application in the analysis of production systems which have exactly one output. Therefore, the objective of this paper is to examine the applicability of StoNED when a ray production function models a production technology with multi-dimensional input and output. In addition to a general analysis of properties required by a ray production function for StoNED to be applicable, we conduct a Monte Carlo simulation in order to evaluate the quality of the frontier and efficiencies estimated by StoNED. The results are compared with those derived via Stochastic Frontier Analysis (SFA) and Data Envelopment Analysis (DEA). We show that StoNED provides competitive estimates in regard to other methods and especially in regard to the real functional form and efficiency.  相似文献

This paper is amongst the first to examine coopetition strategy for sustainable development at the network level. Companies who want to successfully implement complex innovative technologies that support sustainable development need to collaborate with other actors of the innovation ecosystem, including their competitors, so that they can develop standards, interoperable products, pool knowledge, and resources and bundle forces to compete against other technologies. Collaboration with competitors brings benefits, but also many risks. We investigated how firms cope with these risks when establishing an innovation ecosystem to implement a new technology in society. We conducted research in the Dutch smart grids sector and explored how these firms minimize inherent risks of coopetition. We found that system‐building actors in the Dutch smart grid field not only minimize inherent risks, but from the start of their collaboration they implement so‐called enablers to prevent these risks upfront.  相似文献

Research on environmental reporting within individual sectors and industries is limited. Generic studies have typically focused on the reporting practices of the world's largest corporates. Some industries and sectors are under‐represented within these studies, limiting the potential for industry‐ or sector‐specific analysis. Forest and paper is one industry frequently under‐represented. This study examines environmental reporting amongst the top 100 forest and paper companies. The scale of environmental report publication is investigated, and the breadth and depth of reporting on the key industry issues of forest management and fibre procurement examined. The results show reporting is more prevalent amongst larger corporates but marked regional variations are evident. Most noticeably, Scandinavian companies are reporting more extensively, both in terms of the number of levels at which they report and the depth of information included on forest management and fibre procurement. Reasons for the marked regional variations in reporting are considered and markets for forest products and preferences within those markets for specific certification schemes identified as potential influencing factors.

Dimensions of quality upgrading   总被引:2,自引:0,他引:2  
The impact of the Central and Eastern European (CEE) economies’ trade integration with European markets on CEE trade structures has been studied extensively. These studies frequently observe a quality upgrading of CEE exports. In this paper we consider three dimensions of quality upgrading: upgrading across industries, upgrading across different quality segments within industries and, finally, product upgrading within quality segments inside industries. For the analysis we partition industries into quality segments based on EU‐15 import unit values. The results for ten CEE countries (comprising the CEE‐5, the Baltics and South East Europe) and thirteen industries suggest fundamental differences, both across country groups and across the three different notions of quality upgrading. The CEE‐5 show no evidence of entering a ‘low‐quality trap’ in all three dimensions. By contrast, while there is a general catching‐up process across industries and inside quality segments, the second notion of low‐quality specialization may be applicable within the high‐tech industries to the performance for the Baltics and South East Europe as a group.  相似文献

Does Corporate Diversification Destroy Value?   总被引:15,自引:0,他引:15  
We analyze several hundred firms that expand via acquisition and/or increase their number of business segments. The combined market reaction to acquisition announcements is positive but acquiring firm excess values decline after the diversifying event. Much of the excess value reduction occurs because our sample firms acquire already discounted business units, and not because diversifying destroys value. This implies that the standard assumption that conglomerate divisions can be benchmarked to typical stand-alone firms should be carefully reconsidered. We also show that excess value does not decline when firms increase their number of business segments because of pure reporting changes.  相似文献

This paper contributes to the established literature on fiscal consolidations by investigating the distinct behaviour of central and sub‐central tiers of government during general government consolidation attempts. In the light of different degrees of decentralisation across OECD countries, and the different responsibilities devolved to sub‐central tiers, we believe that this approach offers an illuminating insight into the analysis of fiscal consolidations and their success. We show that the involvement of the sub‐central tiers of government is crucial to achieving cuts in expenditure, particularly in relation to the overall size of the government wage bill. In addition, central governments appear to exert a strong influence on the expenditure of sub‐central tiers through their grant allocations, and control of these allocations appears to have a considerable impact upon the overall success of consolidation attempts. Finally, we demonstrate that there is a skewness in cuts towards sub‐central capital expenditure both when central governments cut grant allocations and when sub‐central governments engage in lone consolidation attempts.  相似文献

The new standard for the accounting of insurance contracts (IFRS 17) will entail substantial changes for the insurance industry. In the following article the new standard is critically analyzed. First and foremost the coming valuation model, the so-called building block approach, is presented which will be the basis for all insurance contracts within the scope of IFRS 17. (For certain insurance contracts, especially those with direct participation features, or for less complex or short-term insurance contracts, there are some modifications.) To be more precise, IFRS 17 introduces an enterprise-specific valuation approach that is grounded on the so-called fulfilment value. This fulfilment value is determined by four separate building blocks (fulfilment-cashflow, discount rate, risk margin and contractual service margin), which will be addressed in detail. Finally, major changes in performed accounting practices that insurance enterprises are confronted with and will have to adapt to in their financial statements and accounts are pointed out.  相似文献

Delays in financial reports often reflect issues related to period-end accounting and audit processes. We investigate the impact of filing delays in connection with auditor characteristics on the quality of financial statements in a sample of firms that filed Form 10-K after the statutory due date. We find that late filing firms are associated with lower financial reporting quality compared to timely filing firms matched by propensity scores, where financial reporting quality is measured by the absolute value of performance-matched discretionary accruals and the probability of a late filing being restated in subsequent periods. Furthermore, we demonstrate that the adverse consequences of late filings can be largely mitigated by having a Big 4 auditor. The differential audit quality stems primarily from Big 4 auditors in large offices and is more pronounced when an auditor may need to draw on additional resources in a limited period.  相似文献

Food trucks represent a temporary use of vacant or underutilised land. They have been assumed to increase the livability, vibrancy and attractiveness of a neighbourhood. However, no previous study has investigated whether this effect is reflected in property prices within the surrounding neighbourhood. We investigate the impact of a food truck pod on the values of single-family homes nearby. Using a quasi-experimental design, transaction data from Portland, Oregon and a difference-in-difference specification of a spatial regression model, we find that food trucks actually represent a negative externality, and that proximity of a home to food trucks is penalised by homebuyers. The closer a home is to the food trucks, the lower is the sales price. Explanations for this effect include increased parking shortages and trash issues in a neighbourhood due to food truck visitors.  相似文献

Economics and business students regularly behave less prosocially than others. Can ethics training reverse this tendency? Results from a repeated public goods experiment reveal that it can. Students who attend an interactive lecture on social dilemmas show significantly more cooperation than others. However, the lecture does not appear to increase the incidence of reciprocal behavior. As many current social problems qualify as social dilemmas, this result stresses the importance of ethics training for policy makers and curriculum designers alike in overcoming the incentive structure of social dilemmas.  相似文献
