This paper shows that before (after) fakes’ discoveries, artworks are less (more) likely to be sold through Sotheby’s or Christie’s. Prices only react negatively with a lag, suggesting that sellers try to postpone their sales as long as possible. 相似文献

A large number of claims brought under German D&O insurance regard Insured vs. Insured cases, i.e. claims brought by the company against its own directors and officers (Executive Directors, Supervisory Board Members etc.). After notification of and examination by the insurer of such an insured event, the insurer will in most cases opt to grant the insured defence cover in order to fight off the claim. The insurer hereby expresses that it regards the claim of the company (= its own policyholder) against the board member (= the insured) to be without merit. This situation—where the policyholder is at the same time the damaged party—though typical under (German) D&O-policies is uncommon for liability insurance cover in general. It, thus, raises the issue as to the limits of the policyholder’s duty to disclose information. The scope of said obligation is not unlimited. It rather has to be ascertained pursuant to Sect. 31 VVG (German Insurance Contract Act), by taking into account the policyholder’s interests in commercial and industrial confidentiality and the burden of poof as provided by Sect. 93 para. 2 AktG (German Stock Companies Act). In case legal proceedings ensue between the company and the insured, and, as a consequence, the insurer exercises its obligation to conduct the case for the insured or the insurer joins the lawsuit on the side of the insured (by declaring a Third Party Notice [Streiverkündung]), the insurer clearly becomes an adversary to the company. Under such circumstances, the company is irrevocably released from its duty to disclose information. 相似文献

Council Regulation (EC) 1/2003 came into force in May 2004 and replaced the mandatory notification of agreements by a regime of ex post monitoring. This paper shows that ex post monitoring is the optimal audit regime when the competition authority's probability of error is low. On the other hand, the notification system becomes optimal when the competition authority's probability of error is high. The paper also shows that block exemptions and black list (regimes of per se (il)legality) should be implemented when the agreements’ expected welfare impact is very high and very low, respectively. 相似文献

The contributions of economists have long included both positive explanations of how economic systems work and normative recommendations for how they could and should work better. In recent decades, economics has taken a strong empirical turn as well as having a greater appreciation of the importance of the complexities of real-world human behaviour, institutions, the strengths and failures of markets, and interlinkages with other systems, including politics, technology, culture and the environment. This shift has also brought greater relevance and pragmatism to normative economics. While this shift towards evidence and pragmatism has been welcome, it does not in itself answer the core question of what exactly constitutes ‘better’, and for whom, and how to manage inevitable conflicts and trade-offs in society. These have long been the core concerns of welfare economics. Yet, in the 1980s and 1990s, debates on welfare economics seemed to have become marginalised. The articles in this Fiscal Studies symposium engage with the question of how to revive normative questions as a central issue in economic scholarship. 相似文献

In this study, we comprehensively examine the volatility term structures in commodity markets. We model state-dependent spillovers in principal components (PCs) of the volatility term structures of different commodities, as well as that of the equity market. We detect strong economic links and a substantial interconnectedness of the volatility term structures of commodities. Accounting for intra-commodity-market spillovers significantly improves out-of-sample forecasts of the components of the volatility term structure. Spillovers following macroeconomic news announcements account for a large proportion of this forecast power. There thus seems to be substantial information transmission between different commodity markets. 相似文献

This study investigates how integrated reporting (IR) creates value for investors. It examines how providers of financial capital benefit from an improved firm information environment provided by IR. Specifically, this study investigates the effect of voluntary IR disclosure on analyst earnings forecast accuracy as well as on firm value. To do so, we use an international sample of 167 listed companies that voluntarily publish an integrated report. Our analysis shows no significant effect of a voluntary IR publication on analyst earnings forecast accuracy and no significant effect on firm value. We thus do not find evidence for the fulfillment of IR's promises regarding improved information environment and value creation of voluntary adopters. We conclude that such companies might already have a relatively high level of transparency leading to an absent additional effect of IR disclosure. Positive effects of IR appear to be more relevant in environments where IR is mandatory. 相似文献

Sustainable management of natural resources, and in particular fisheries, must take into account several conflicting objectives. This is the case in the French Guiana shrimp fishery for which profitability objectives imply a reduction in the fishing activity. On the one hand, this fishery has negative externalities on marine biodiversity due to discards. On the other hand, this fishery has positive externalities on the economy of the local community and interestingly enough on a protected seabird species in the area (the Frigatebird that feeds on discards). In this paper, we examine the viability of that system considering two sustainability objectives: an economic objective in terms of the profitability of the fishing activity, and a conservation objective in terms of the Frigatebird population. For that purpose, we have developed a dynamic model of that bioeconomic system and study here the trade-offs between the two conflicting objectives. It provides a means to quantify the necessary give and takes involving the economic and ecological objectives that would ensure a viable management solution. Our study confirms the relevance of the viability approach to address natural resource management issues, which should lead to the development of new tools for the arbitration of conflicting sustainability objectives. In particular, such tools could be used as a quantitative basis for cost–benefit analysis taking into account environmental externalities. 相似文献
