This paper analyzes the interaction between migrants’ income and remittances and between remittances and the labour supply of residents. The model is cast as a two-period game with imperfect information about the residents’ real economic situation. Residents subject to a good economic situation may behave as if they were in a poor economic situation only in order to manipulate remitters’ expectations. The latter, being aware of this risk, reduce the remitted amount accordingly. Therefore, in the equilibrium, residents who really are victims of the bad economic outlook are penalized as compared to the perfect information set-up. In some circumstances, they can signal their type by drastically cutting working hours, thus further enhancing their precarity right when their economic situation is the worst.  相似文献

The measurement and recognition of intangible assets: then and now   总被引:1,自引:0,他引:1  
Claire Eckstein   《Accounting Forum》2004,28(2):139-158
“In the Fortune 500 there are thousands upon thousands of statistics that reveal very little that’s meaningful about the corporations they purportedly describe. At least that’s the verdict of a growing number of forward-thinking market watchdogs, academics, accountants, and others.”(Fortune, April 2001). In today’s economy value is often created by intangible (intellectual) capital. The accounting profession has not met the challenge of measuring and reporting the results of knowledge-based entities. The Federal Reserve Bank of Philadelphia estimates that in the year 2000 more than US$ 1 trillion was invested in Intangibles. The problems relating to the measurement and recognition of intangibles are international in scope.This paper reviews existing and recently promulgated US, UK, and IASC accounting standards relating to Intangibles. Inconsistencies in the measurement and reporting of Intangibles under US Generally Accepted Accounting Principles (GAAP) are highlighted, and evidence is provided that suggests that recognition of Intangible (Intellectual) Capital is in accordance with existing accounting principles In particular, the newly promulgated Financial Accounting Standards Statements on Business Combinations, Goodwill, and other Intangibles is reviewed. The objective of the comparisons to UK and IASC standards and the review is to provide evidence that will improve the measurement and reporting of intangible (intellectual) capital and facilitate harmonization. Improving the global financial reporting infrastructure will ultimately lead to the reporting of relevant and reliable quality earnings.  相似文献

Consumer involvement or patient and public involvement (PPI) in health research is a UK policy imperative and a prerequisite for many funders. PPI in research is defined as research carried out with or being carried out by the public (or service users), rather than research on patients and public as subjects or participants. Despite the clear policy driver, there is relatively little empirical evidence on the extent, processes and impact of user involvement in research. This paper aims to add to the international evidence base on PPI in research by providing a key overview of current trends and impacts. In order to understand the current extent and variation of PPI in research, a scoping exercise and survey were carried out on selected UK studies. Six research topic areas (cystic fibrosis, diabetes, arthritis, dementia, intellectual and developmental disabilities, and public health) were selected to ensure a range of designs, study populations and histories of PPI in research. A total of 838 studies (non‐commercial studies and not older than 2 years) were contacted. The response rate for the scoping was 38% and the survey 28%. In the scoping, 51% of studies had some evidence of PPI and in the survey 79%. The most common PPI activity was steering committee membership and reviewing patient information leaflets. There appeared to be some blurred roles with patients participating as research subjects as well as carrying out patient involvement roles. A major finding was the limited amount of available information about PPI in publicly accessible research documents. We suggest that the invisibility of this type of involvement and the lack of routinely collected information about PPI results in a lack of shared understanding of what optimal PPI in a study should look like, with important implications for practice. Furthermore, without a framework to review PPI it is difficult to know if different approaches to PPI have a different impact on key outcomes of the research.  相似文献

Abstract

This paper examines the arguments advanced by Rousseau to explain his rejection of monetary exchange. First we show that the rejection of money as mean of exchange expresses a dismissal of any form of exchange, motivated by a need for independence. In Julie, the community of Clarens exemplifies an autarchic, paternalistic economy that is at once unequal and deceptive. To understand why Rousseau chose such a downbeat solution to the problems arising from the organisation of the division of labour, we make a parallel between the economic and amatory themes, showing in each case the dependence upon others produced by the development of amour-propre.  相似文献

Conversion of farmland to non-agricultural uses presents a challenge to future food production and ecosystem services in US and Canada. Expansions of housing, transportation, industry, retail sales, schools and other developments are driving land out of farming. In the US there is annual conversion of 500,000 ha away from food and fibre production systems. Coupled with 1% annual population increase, this will reduce today's 0.6 ha per person to 0.3 ha by 2050. Canada has more land and smaller population, but farmland losses are occurring in fertile areas near coasts and in level valleys where highest quality land is located. Current rates of increase in agricultural productivity will not compensate for this land loss. Compared to US, there are more specific tools and legislation at the provincial level in Canada that provide opportunities for controlling sprawl. Important in both countries is general lack of awareness and concern about loss of productive farmland, a situation that could be improved through education. Stimulating collective understanding of this growing problem and providing viable solutions could provide the basis for national policy strategies to promote and assure sustainable food systems for the future and enhance the capacity to maintain vital ecosystem services.  相似文献

Nature-based tourism provides an ideal context for motivating pro-environmental action, as it draws travellers interested in the natural world and showcases unique, and often threatened, environments. This study examines efforts to motivate environmentally related behaviour in tourists' everyday lives using a technology-based intervention following an elephant seal viewing tour at California's Año Nuevo State Park. A total of 362 visitors completed pre-tour and post-tour surveys, with 94 visitors completing a final survey three months after the tour. We found that, although the intervention had little influence on conservation action overall, it was effective for a social media-related action. Post-tour conservation actions were significantly affected by emotional connection to wildlife during the tour and repeat visitation to either the same or another state park. We found that visitors' connectedness to nature increased during the three-hour tour, but returned to pre-visit levels three months later. Practical implications include that parks should encourage repeat visits, suggest an assortment of other experiences that support connecting to nature, and link their conservation messaging to visitors' close, personal, and emotional experiences with fauna. We suggest that one simple, yet effective, way to do this is through maintaining the visitor–park experience through a social media community.  相似文献

The use of private air travel for business trips has expanded rapidly over the past few decades. We estimate that the number of U.S. domestic passenger trips per year on business aircraft exceeded 17 million in 2007, or a number equal to about 40 percent of combined domestic first-class, business-class, and full-fare coach airline trips—travel options for which passengers also pay a premium for timeliness, comfort, or privacy. Once a company determines that it can benefit from private business travel, it generally identifies the most cost-effective option, including the operating characteristics of the aircraft and the options for obtaining this service. This paper examines some of the factors that influence decisions on these options, with particular emphasis on the financial and program alternatives that are making it less costly for business travelers to take advantage of private jet travel, thereby expanding its use. Our findings indicate that the customary view of these options is oversimplified and ignores the new ownership (or non-ownership) models for obtaining use of a business aircraft.  相似文献
