Informations- und Beratungspflichten des Versicherers nach der VVG-Reform

The insurer’s duty to enable the customer to come to an appropriate decision, providing advice and information, is a central topic of the reform of the German insurance contract law. The obligations of intermediaries given by the Directive 2002/92/EC on insurance mediation are transferred to insurers and thereby enlarged in some aspects. The duty to give advice in §6 I 1 VVG depends on the objective circumstances of each individual case depending upon either the complexity of the insurance contract and problems in understanding its terms, or the characteristics and situation of the customer. Therewith, the regulation both refers to former jurisdiction and exceeds it by implementing a duty for the insurer to ask for the demands and the needs of the customer. Without reason in the special case the customer has to disclose his need for advice to obtain it. During the term of the contract the insurer is only obliged to give advice if he knows or — acting diligently — could know the needs of the policy-holder. On a European level further duties to inform and advise could help to achieve an effective internal insurance market.

Legitimizing Negative Aspects in GRI-Oriented Sustainability Reporting: A Qualitative Analysis of Corporate Disclosure Strategies

Corporate sustainability reports are supposed to provide a complete and balanced picture of corporate sustainability performance. They are, however, usually voluntary and thus prone to interpretation and even greenwashing tendencies. To overcome this problem, the Global Reporting Initiative (GRI) provides standardized reporting guidelines challenging companies to report positive and negative aspects of an organization’s sustainability performance. However, the reporting of “negative aspects” in particular can endanger corporate legitimacy if perceived by the stakeholders as not being in line with societal norms and values. Starting from the theoretical lenses of economics-based disclosure theories and socio-political theories of disclosure, the focus of this study therefore was to analyze the communicative legitimation strategies companies use to report “negative aspects,” i.e., negative ecological and social impact caused by corporate activity. Using qualitative content analysis of GRI-oriented sustainability reports from companies listed on the US Dow Jones Industrial Average Index and on the German DAX Index, we identified six legitimation strategies. We discuss these strategies regarding to symbolic and substantial management of legitimacy. We show that symbolic legitimation strategies aiming at modifying the perception of legitimizing stakeholders dominate in the reports at hand. Such persuasion, however, does not meet the requirement of impartiality as postulated by the GRI guidelines. Building upon this conclusion we propose a concise characterization of “negative aspects” and develop a GRI-compliant schema of reporting about them. In doing so, we offer a way to improve the overall “balance” of sustainability reporting contributing to a true and fair view in sustainability disclosure.     

Exotic Passport Options

The Vanilla Passport Option is an insurance against trading loss. In this paper, we add various exotic features to the Vanilla contract and price the resulting financial products. The assumptions that we make are the same as the Black-Scholes ones and the resulting pricing equations are Hamilton-Jacobi-Bellman type equations or parabolic free boundary PDE's which can be solved via finite difference methods.     

Coming and going: Experiments on endogenous group sizes for excludable public goods

When a public good is congestible, individuals wanting to provide the public good face challenges in forming groups of optimal size, selecting the members of the group, and encouraging members to contribute for the public good. We conduct a series of experiments in which subjects form groups using three different entry and exit rules. The experimental results are analyzed in terms of group size, the level of public good provision, social efficiency, congestion and group stability. We find that entry restriction improves the average earnings for some individuals compared to free entry/exit or restricted exit. For a given group size, individuals under the restricted entry rule contribute more for the provision of the collective good. Also, for a given average contribution level of group members, subjects under the restricted entry rule suffer less from the congestion problem and are better able to form groups of sizes closer to the optimal.     

Portfolio Performance Measurement: a No Arbitrage Bounds Approach

This paper presents a new method to examine the performance evaluation of mutual funds in incomplete markets. Based on the no arbitrage condition, we develop bounds on admissible performance measures. We suggest new ways of ranking mutual funds and provide a diagnostic instrument for evaluating the admissibility of candidate performance measures. Using a monthly sample of 320 equity funds, we show that admissible performance values can vary widely, supporting the casual observation that investors disagree on the evaluation of mutual funds. In particular, we cannot rule out that more than 80% of the mutual funds are given positive values by some investors. Moreover, we empirically demonstrate that potential inference errors embedded in existing parametric performance measures can be of important magnitude.     

Does fiscal policy influence monetary policy? The case of Spain, 1874-1935

The Spanish peseta never formally belonged to the gold club, neither the classical nor the exchange-rate gold standards. It has been traditionally argued that the reason was the predominance of deficits in the Spanish budget from 1874 to 1935. The financing needs of the Treasury led to money creation and, consequently, to sacrificing the gold commitment and a fixed exchange rate. Applying a stationary VAR (Vector AutoRegressive) model, this paper estimates the dynamic link between budget and money and tests whether Spanish fiscal policy actually influenced monetary policy. The results confirm the dominance of fiscal policy for the period and, therefore, provide empirical support to the idea that the problems of the Treasury were behind Spain’s renouncement of gold.     

Price clustering on the limit-order book: Evidence from the Stock Exchange of Hong Kong

We examine the clustering pattern in trade and quote prices on the electronic limit order book of the Stock Exchange of Hong Kong (SEHK). Earlier research into clustering focuses on transaction prices only. We study clustering on quote prices over a maximum of five queues on the limit order book. We observe an abnormally high frequency of even and integer prices in trade and quote prices for all tick size groups on the SEHK. The deeper quotes display stronger clustering than the best quotes, indicating that the farther away the quotes are from the best queue, the less information they carry. Our analysis further reveals that an extremely fine tick size itself works as a binding constraint to hinder the price resolution process. We also find that short sale prohibition imposed on the majority of stocks listed on the SEHK causes a significant bias in clustering towards the ask side of the limit order book. This implies that a short sale prohibition impairs efficient price discovery in the market.
