What cloud interoperability connotates for EU policy making: Recurrence of old problems or new ones looming on the horizon?

One of the key factors for a thriving cloud computing market is the ‘interoperability’ between the relevant hardware and software that govern the cloud services. While a complete interoperability means different cloud users being able to exchange the management tools, server images and other software, this is infrequently realised because users are locked into (proprietary) cloud ecosystems. This (problem of vendor lock-in) is potentially accompanied with another problem revolving around the content delivery networks being integrated with the distinct clouds along with possible harms to media pluralism as well as interoperability. In view of these concerns, this study focuses on competition law, standardisation and regulatory policies, and elaborates on to what extent cloud interoperability needs to be secured under EU legal fora. Overall, it is found that vendor lock-in might be attended by ‘coupling’ and complex ‘layering’ strategies, whereas efficiency and/or security based justifications would arise as the counter-balancing reasons. Based on the findings, the study concludes that while focusing on the vertical (i.e., vendor lock-in) concerns, a comprehensive viewpoint needs to be upheld, allowing efficiencies (i.e., proprietary enhancements) based on the architectural design and innovations, obviating narrowly-fashioned (i.e., foreclosure-based) interventions such as in Microsoft case. It is also underlined that cloud interoperability has a content dimension that would require a broader perspective, extending to horizontal concerns and requirements within the context of EU policy making strategies.     

Technical Efficiency of the Brazilian Municipalities: Correcting Nonparametric Frontier Measurements for Outliers

In this paper we estimate the DEA technical efficiency for 4796 Brazilian municipalities, by applying a recently proposed “Jackstrap” method, which combines Bootstrap and Jackknife resampling techniques, to reduce the effect of outliers and possible errors in the data set. We perform calculations to identify and eliminate high leverage municipalities, using different variants of Data Envelopment Analysis (DEA), as well as Free Disposal Hull (FDH). Corroborating previous results, efficiency results for the Brazilian municipalities show a clear relationship between the size of the municipality and its efficiency scores. Indeed, under both DEA variants, smaller cities tend to be less efficient than larger ones hence indicating that the quality of the frontier adjustment improves significantly as the size of the municipality increases. We present arguments that may explain to some extent these findings, such as economies of scale and the excess spending due to revenue from royalties. However, such effects require further, more careful examination.     

董事网络:定义、特征和计量

董事的行为镶嵌于社会网络,本文定义了"董事通过在董事会同时任职建立的直接和间接联结关系"而形成的董事网络,并从"结点"和"关系"两个维度界定了董事网络的边界;基于社会学的镶嵌理论、弱联结优势理论、结构洞理论和社会资本理论分析了其社会网络特征,也利用社会网络分析方法对董事的网络中心程度进行了计量;最后简析了独立董事在我国上市公司董事网络中的核心地位和如何基于董事网络对独立董事治理行为展开研究。本研究可为我国"社会网络和公司治理"交叉研究的展开提供一定的理论基础。     

Fundraising and Optimal Policy Rules

This paper develops a simple spatial model of fundraising, in which charities select a target population to solicit donations. First, we show that in a competitive charity market without any intervention, the number of charities in the market and/or the overall net funds raised by charities may be suboptimal. Next, we analyze whether a social planner can prevent such shortcomings and show that a regulatory mechanism can be designed to achieve socially desirable outcomes. In contrast to the previous literature, our model does not necessarily produce monopoly as the optimal market structure. We show that if fixed costs associated with establishing charities are sufficiently low, then the optimal market structure is not a monopoly. Given the importance of the trade‐off between the volume and variety of charitable services, we argue that this result may be of particular interest to policy makers.     

Wie viel IT braucht die Pflege?

Die Einführung von IT-Systemen in Gesundheitseinrichtungen ist vor allem getriggert durch betriebswirtschaftliche, den Erl?s sichernde Faktoren. Eine echte Unterstützung der pflegerischen Leistungsprozesse steckt allerdings bei vielen IT-L?sungen noch in den Kinderschuhen.     

Stabilizing Endogenous Instability: Proposals for An Institutionalist Reform of Financial Regulation

A major and persistent question behind economic theories and related policies is whether the market can self-regulate without any restrictive exogenous intervention or whether regular and binding public regulation is necessary for ensuring the reproduction of the economic system in a sustainable way over time. This article considers this question with regard to the working of financial markets in a liberalized environment. Drawing upon an institutionalist stance, the article shows why the operation of a financialized capitalist economy usually leads to systemic imbalances and crises. The article then suggests an alternative framework for a consistent financial regulation that could prevent market actors from developing short-sighted strategies and gambling on macro stability.     

Pricing Reinsurance Contracts on FDIC Losses

This paper proposes a pricing model for the FDIC's reinsurance risk. We derive a closed‐form Weibull call option pricing model to price a call‐spread a reinsurer might sell to the FDIC. To obtain the risk‐neutral loss‐density necessary to price this call spread we risk‐neutralize a Weibull distributed FDIC annual losses by a tilting coefficient estimated from the traded call options on the BKX index. An application of the proposed approach yield reasonable reinsurance prices.     

The Effect of Regulatory Harmonization on Cross‐Border Labor Migration: Evidence from the Accounting Profession

The paper examines whether international regulatory harmonization increases cross‐border labor migration. To study this question, we analyze European Union initiatives that harmonized accounting and auditing standards. Regulatory harmonization should reduce economic mobility barriers, essentially making it easier for accounting professionals to move across countries. Our research design compares the cross‐border migration of accounting professionals relative to tightly matched other professionals before and after regulatory harmonization. We find that international labor migration in the accounting profession increases significantly relative to other professions. We provide evidence that this effect is due to harmonization, rather than increases in the demand for accounting services during the implementation of the rule changes. The findings illustrate that diversity in rules constitutes an economic barrier to cross‐border labor mobility and, more specifically, that accounting harmonization can have a meaningful effect on cross‐border migration.
