This paper contributes to the literature on career concerns and corruption by drawing on extensive information on the performance of referees and records from Calciopoli, a judicial inquiry carried out in 2006 on corruption in the Italian football league. Unlike previous studies, we can analyse in detail the assignment of the referees to the most important matches, which is an important step in their career. Moreover, we can relate this choice to the performance of referees in previous matches and the evaluations they received in this context. We find that referees involved in match rigging were promoted to top games and that their evaluation was not negatively affected by their involvement in documented episodes of match rigging. 相似文献

AbstractCrypto-currencies, or crypto-assets, represent a new class of investment assets. The traditional portfolio analysis approach of Markowitz is not appropriate for use with portfolios containing crypto-assets, as the model requires that the investor have a quadratic utility function or that the returns be normally distributed, which isn’t the case for crypto-assets. We develop a portfolio optimization model based on the Omega measure which is more comprehensive than the Markowitz model, and apply this to four crypto-asset investment portfolios by means of a numerical application. The results indicate that these portfolios should favor traditional market assets over crypto-assets. In the case of portfolios formed only by crypto-assets, there is no clear preference in favor of any crypto-asset in particular. 相似文献

In the mid-1990s, global labour standards emerged as a new and important are of concern for socially responsible investors, especially with respect to investments in the "problematic" footwear, apparel, and toy industries. In this paper, I elucidate the primary areas of concern for investors and discuss a framework for evaluating firms' labor standards performance. In addition, I argue that today's sweatshop debates follow closely those of centuries ago, with the standard economic defense of low wage manufacturing on the one hand, and the activists' protests against poor conditions and wages on the other. An examination of this historical context reveals a promising middle ground in this ongoing debate. 相似文献

Convergence to the Lisbon employment targets requires absorbing large pools of long-term jobseekers, increasing labour force
participation and dealing with a sizeable informal sector, composed for the most of low-productivity jobs. The purpose of
this paper is to review the main design features of an activating social security strategy reconciling shifts of these three
margins with the redistributive institutions characterising the European landscape. Evidence of experimental studies is reviewed.
It is argued that EU supra-national authorities should confine themselves to promoting the exchange of information about best
practices in welfare-to-work policies as implementation of this approach should be done at a decentralised level. Issues related
to the implementation of this activating strategy in the countries that are more distant from the Lisbon targets are also
discussed.
A first draft of this paper was prepared for the Dutch Presidency Conference on ‘More People at Work’, Amsterdam, 25–26 October,
2004. I am grateful to participants in that conference, Henk Don and two anonymous referees for valuable comments. 相似文献

We study the impact of competition on banks’ risk-taking behavior under different assumptions about deposit insurance and the dissemination of information. While financial opening increases banks’ riskiness, a risk-based deposit insurance or, alternatively, the public disclosure of financial information, are likely to mitigate this effect. Moreover, the limiting cases of uninsured but fully informed depositors, and risk-based full deposit insurance, yield the same equilibrium risk level. Although the welfare consequences of increased competition depend on its impact on risk, financial opening unambiguously improves welfare as we approach the limiting cases. 相似文献

AbstractWe examine the recent changes that have affected the Italian accounting scenario after the adoption of the IFRS and the enactment of the European accounting system. In particular, we have focused our attention on the decision of the legislature to enlarge the mandatory adoption of IFRS to non-listed companies and to individual financial statements (FS). At the same time, we have observed the changes determined by the EU Directive 2013/34 on the Italian Civil Code and the FS legislation. Both set of changes are describing a process under which the Italian accounting rules are moving towards the international accounting standards and their framework, contents and methods. Therefore, the main differences among national rules and IFRS are grounded on the measurement rules and the role played by the historical cost principles and the strict and detailed regulation of the Balance sheet and Income statement formats. 相似文献

Patterns of Trade and Oligopoly Equilibria: An Example 总被引:1,自引:0,他引:1
Tito Cordella 《Review of International Economics》1998,6(4):554-563
This paper investigates, via an example, the effects of oligopolistic competition in a two-country two-good "Ricardian" model of international trade. By contrast with results that apply to the competitive free-trade equilibrium, at the oligopoly equilibrium industries with different technologies can profitably survive. Moreover, it is shown that, in an oligopolistic setting, the pattern of trade cannot be inferred either by pre-trade prices or by the comparative advantage principle. 相似文献

In June 2004 the IASB issued the Discussion Paper ‘Preliminary Views on Accounting Standards for Small and Medium-Sized Entities’. This invited comments on the central question of whether the IASB should develop separate standards for small and medium-sized enterprises (SMEs), and on further issues and questions arising from this. This paper briefly introduces the background to the publication of the Discussion Paper. This is followed by a review of prior literature on SME financial reporting implications, prepared by the European Accounting Association's Financial Reporting Standards Committee as the basis of its response to the Discussion Paper. The paper concludes with a brief summary of events and issues arising since the end of the consultation period. 相似文献

Summary. We consider two periods economies with both intrinsic and extrinsic uncertainty. Asset markets are incomplete in the certainty economy. If assets are nominal, there are enough commodities and the number of agents is greater than two and smaller than the total number of states of nature tomorrow (minus one), then a sunspot-invariant equilibrium is generically Pareto dominated by some sunspot equilibria. When assets are real, and there are enough commodities, if there are sunspot equilibria, there are sunspot equilibria Pareto dominating sunspot-invariant equilibria under the same restriction on the number of agents (and stronger restrictions on the number of commodities).Received: 20 October 2003, Revised: 1 April 2004, JEL Classification Numbers:
