Regulators would often like firms to adopt systems of internal control, such as Environmental Management Systems. This paper examines a choice for such a regulator, whether to make such internal controls mandatory. If even unenthusiastic firms are required to institute their own systems, some of them may do so in a perfunctory or cosmetic fashion. With voluntary controls, firms that do not institute systems of internal controls can be obliged to follow specification standards instead. A disadvantage of mandatory controls is highlighted; more compromises have to be made in designing the regulatory framework.  相似文献

We examine the patterns of goodwill impairments in Europe and in the US over the period from 2006 to 2015, for a sample of more than 35,000 firm-year observations. We define the timeliness of goodwill impairments as the frequency of accounting impairments conditional to indications of economic impairments. We measure indications of economic impairment with three metrics: equity market value minus equity book value less than goodwill, market-to-book smaller than one and negative earnings before interest, tax, depreciation and amortisation (EBITDA). Our research strategy leads us to draw very different conclusions than those in the recent EFRAG (2016) study. While median levels of goodwill on the books between US and European firms are relatively similar, we find several indications that US firms recognise timelier impairments, at least during 2008 and 2009, that is, the early years of the financial crisis. We further document that US impairers write down a much greater percentage of their beginning balance of goodwill than European impairers. During the financial crisis, the median level of impairment by US firms was 63% of opening goodwill in 2008 and 40% in 2009, whereas median European write-downs were only 6% and 7% of opening goodwill, respectively. Even though European firms are more likely to impair over multiple years, the cumulative impairments never come close to the level of US firms, be it in a single year or cumulative over multiple years. We also find that the frequency of accounting impairment is small compared to the number of firms presenting evidence of economic impairment: only 20–25% of firms recognise impairments depending on the measure of economic impairment. This has often been interpreted by academics as a sign of untimely write-offs. Accounting differences between US Generally Accepted Accounting Principles and International Financial Reporting Standards are unlikely to explain our results. One caveat of our analysis is that it does not allow us to draw conclusions on whether the observed differences between US and European firms are driven by differences in conditional conservatism and/or big bath accounting practices.  相似文献

Programs to reduce traffic congestion and air pollution by restricting use of motor vehicles on working days have generally not met with success, given existing studies of such programs. We conduct the first study of Quito, Ecuador's four‐year‐old Pico y Placa program and find that it has reduced ambient concentrations of carbon monoxide (CO), a pollutant primarily emitted by vehicles, by 9% to 11% during peak traffic hours. Given that ambient concentrations of CO generally track the spatial and temporal distributions of traffic, these reductions in pollution suggest similar reductions in vehicle flows. We find no significant evidence that traffic has shifted to other times of the day or week, or to other locations.  相似文献

This paper shows how the interaction between decentralized information gathering and discreteness of investment decisions at the individual level can generate random fluctuations in aggregate investment that involve occasionally large allocation errors. This interaction is illustrated in a model in which private information is costly to acquire and prices reveal information. The unique rational expectations equilibrium outcome of the model is shown to always be noisy and characterized by investment levels which may be high simply because uninformed investors are buying under the impression that the high price is a signal of good investment opportunities.  相似文献

This paper examines the relative impact of economic freedom, civil liberties, and political rights on growth. A system of three simultaneous equations is used to unearth the channels through which these institutional dimensions affect economic growth. These include greater efficiency and enlarged investment in physical and human capital. The sample contains 79 countries and six periods covering the years from 1976 to 2005. The results show that the three dimensions of institutional quality are important for economic growth either through a better allocation of resources or, indirectly, through the stimulation of investment in physical and human capital.  相似文献

The essays collected in this forum discuss the geopolitical legacy of the Russian Revolution of 1917, one of the most momentous political events of the twentieth century. From a range of different academic disciplines and perspectives, the authors consider how the profound transformations in society and politics were refracted through space and geography, and how enduring these refractions proved to be. The authors focus on three themes that have been dominant in Russian affairs over the past century: 1)the problem of center-periphery relations, 2)the civilizational dynamics of Russia’s self-identification in relation to Europe and to Asia, and 3)the geopolitics of national identity.  相似文献

Financial literacy education features prominently among the policy options available to improve personal financial decision‐making. Notwithstanding calls to expand delivery of financial literacy units at university level, such offerings are relatively rare with little evaluation. We provide an evaluation of the impact on financial literacy, financial attitudes and financial behaviour intentions of a semester unit in personal finance delivered to undergraduates at an Australian university, carefully controlling for confounding effects in the analysis. We report increases in objective and subjective financial literacy and an additional gender effect. Contrary to previous speculation, we do not find overconfidence as an associated outcome.  相似文献

While it is crucial to understand the impact of regulatory changes on market risk, the literature does not show how risk responds to expected regulatory changes that are specifically designed to change risk. Our paper fills this gap by providing a detailed study of one such case. Using both a sample of privatized U.K. companies, and U.K. and U.S. control portfolios, between 1993 and 2000, we show (both for the single-factor market model and the three-factor Fama-French model) that the observed changes in market risk are significant and consistent with theory.  相似文献
