MEASURING RICHNESS AND POVERTY: A MICRO DATA APPLICATION TO EUROPE AND GERMANY

In this paper, we define a new class of richness measures. In contrast to the often used headcount, these new measures are sensitive to changes in rich individuals' incomes and, therefore, allow for a more sophisticated analysis of richness. We demonstrate the application of these new measures in analyzing the development of poverty and richness over time in Germany. Moreover, we compare Germany to many other European countries and investigate the impact of tax reforms on poverty and richness. Using these examples, we show the importance of taking the intensity of changes into account and not only the number of people beyond a given richness line (headcount). We propose to use the new measures in addition to the headcount index for a more comprehensive analysis of richness.     

Reassessing Moral Legitimacy in Times of Instability

The presence of conflicting cues about what is legitimate provided by various stakeholders, begs the question of how the legitimacy of contested institutionalized practices is justified. Recent critique of tax minimization strategies exemplifies this difficulty: on one hand, practitioners need to increase shareholders' profits; on the other, a growing number of stakeholders push for ‘fairer’ corporate tax payments. Conducted during a time of public criticism of Australian corporate tax strategies, our study draws on justifications of corporate tax minimization strategies by senior tax practitioners and corporate submissions to a Senate Inquiry on corporate tax avoidance. The study explores how legitimacy judgements come under pressure by conflicting cues. Through the application of Boltanski and Thévenot's (2006) Economies of Worth (EW) framework, we advance legitimacy scholarship by clarifying what constitutes situated judgements in times of instability. Our work puts forward the concept of perceived forecasted consensus as a guide for individuals in making situated legitimacy judgements in times of instability.     

Ex ante identification of disruptive innovations in the software industry applied to web applications: The case of Microsoft's vs. Google's office applications

This paper analyzes the question whether web applications pose a disruptive threat to incumbents or a disruptive growth opportunity for entrants in the application software industry using a novel method for ex ante identification of disruptive innovations in the software industry. Building on the theory of disruptive innovations, network effects and existing frameworks for the ex ante identification of disruptive innovations a new method of analysis is deduced. The analysis is based on a list of criteria that indicate a disruptive innovation and trajectory maps of the technologies' performance attributes. This method is applied to study the potential disruption of Microsoft's desktop office applications by Google's web-based office applications.The chosen method of analysis indicates a small likelihood for web applications to pose a disruptive threat to Microsoft, and by extension, to incumbents in the software industry. While web applications show a potential to satisfy market demand in established performance attributes, strong network effects in existing software products should give incumbents enough time to co-opt the innovation. The case illustrates how our new method to analyze disruptive potential in the software industry ex ante can help to apply the theory of disruptive innovation better for forecasting purposes and to provide novel strategic insights for the players involved.     

Cost data quality considerations for eco-efficiency measures

Cost data are a central aspect of eco-efficiency measures, either as means to assess value of production, or, more directly, as one dimension of the efficiency ratio. Several aspects may affect the quality of cost data, among them definitions, time and space, and confidentiality issues. Somewhat surprisingly, cost data quality has received little attention in the field of sustainability and eco-efficiency so far. Even worse, perhaps, is the lack of tools suitable for a cost data quality assessment and management.This paper discusses parameters that affect cost data quality, and will then propose a pedigree matrix as a tool designed for managing cost data quality issues. The application of the matrix is described, also in combination with a previously proposed, and broadly used, pedigree matrix for environmental data quality management.     

When prices hardly matter: Incomplete insurance contracts and markets for repair goods

This paper looks at markets characterized by the fact that the demand side is insured. In these markets, a consumer purchases a good to compensate consequences of unfavorable events, such as an accident or an illness. Insurance policies in most lines of insurance base indemnity on the insured's actual expenses, i.e., the insured would be partially or completely reimbursed when purchasing certain goods. In this setting, we discuss the interaction between insurance and repair markets by focusing, on one hand, upon the development of prices and the structure of markets with insured consumers, and, on the other hand, the resulting backlash on optimal insurance contracting. We show that even in the absence of ex post moral hazard the extension of insurance coverage will lead to an increase in prices as well as to a socially undesirable increase in the number of repair service suppliers if repair markets are imperfect.     

智慧BIM乔木模型：从设计图纸到施工 现场

现有的BIM应用软件提供的乔木模型多为RPC或高 精度3D模型等3D CAD类型。这些模型着重于表达美感或进 行展示,无法反映根系情况。虽然可能包含一定附加属性,但 表达乔木生长和空间需求的功能有限。因而,冲突检查、工序 调度等BIM的优势功能无从应用。风景园林实践领域已就此问 题开始构建自己的模型库,但能够准确反映现状树木真实尺寸 体量,以及现状树木和规划树木未来空间需求的模型仍未广泛 出现。提出一种基于树冠、树干和根系构型与生长功能的实体/ 网面封装建模方法构建BIM乔木模型。模型形态通过一组参数 调整,并根据树龄和反映环境限制因子的值来反映其变化。所 包含的数据和参数数量随后期设计阶段所需的LoD(详细层级) 及专业实践的具体要求而增加。该模型可以与提供本地区内外 苗木商品信息的植物数据库连接使用。     

Does the reliability of institutions affect public good contributions? Evidence from a laboratory experiment

Reliable institutions, i.e., institutions that live up to the norms that agents expect them to keep foster cooperative behavior. We experimentally confirm this hypothesis in a public goods game with a salient norm that cooperation was socially demanded and corruption ought not to occur. When nevertheless corruption attempts came up, groups that were told that ‘the system’ had fended off the attempts made considerably higher contributions to the public good than groups that learned that attempts only did not affect their payoffs or that were not exposed to corruption at all.     

WILL GERMAN BANKS EARN THEIR COST OF CAPITAL?

In recent years, the German banking sector has overcome major challenges such as the global financial crisis and the European debt crisis. This paper analyzes a recent development as a particular determinant of the future outlook for the German banking sector. Interest rates are at historically low levels and may remain at these levels for a considerable period of time. Such levels pose a specific challenge to banks which are heavily dependent on interest income, as is the case for most German banks. We consider different interest rate scenarios and analyze the extent to which they cause a further narrowing of the interest rate margin. Our results indicate that a projected decline in this margin will result in no more than 20% of German banks earning a cost of capital of 8% by the end of this decade. However, we show that this decline is alleviated by the fact that German banks can apply a special feature of German accounting standards by using hidden and open reserves. We discuss how these income smoothing tools will provide a cushion that supports short‐ and medium‐term adjustments through a buffer effect. (JEL G21, G28)     

On the self-interested use of equity in international climate negotiations

We discuss self-interested uses of equity arguments in international climate negotiations. Using unique data from a world-wide survey of agents involved in international climate policy, we show that the perceived support of different equity rules by regions may be explained by the ranking of their economic costs. Despite being self-interested, equity arguments may be perceived as being used for different reasons, for example, out of fairness considerations or in order to facilitate negotiations. Consistent with experimental and behavioral studies on fairness perceptions, we find that individuals are more likely to state reasons with positive attributes if they evaluate their own region or regions that support the individual's personally preferred equity rule. Negotiators perceive the use of equity by regions as less influenced by pressure from interest groups.     

Monetary policy under a fiscal theory of sovereign default

This paper examines equilibrium determination under different monetary policy regimes when the government might default on its debt. We apply a cash-in-advance model where the government does not have access to non-distortionary taxation and does not account for initial outstanding debt when it sets the income tax rate. Solvency is then not guaranteed and sovereign default can affect the return on public debt. If the central bank sets the interest rate in a conventional way, the equilibrium allocation cannot be determined. If, instead, money supply is controlled, the equilibrium allocation can uniquely be determined.
