We examine differences in price delay for a sample of real estate investment trust (REIT) and non-REIT matched pairs. Results suggest an economically and statistically higher level of price delay for REIT securities, which implies heightened frictions that increase the time needed for new information to be impounded into the prices of REIT shares. The primary drivers for the observed delay differential include differences in idiosyncratic volatility, market risk, and the number of days traded. Within-REIT determinants of delay confirm findings for the pooled sample of matched pairs. Importantly, we infer find that REIT investors are not compensated for restricted information flow, as excess returns are unrelated to the price delay.  相似文献

Property rights and information flows: a simulation approach   总被引:1,自引:0,他引:1  
With the growth of the information economy, the proportion of knowledge-intensive goods to total goods is constantly increasing. Lessig (The future of ideas: the fate of the commons in a connected world. Vintage, New York 2001) has argued that IPRs have now become too favourable to existing producers and that their ‘winner-take-all’ characteristics are constraining the creators of tomorrow. In this paper we look at how variations in IPRs regimes might affect the creation and social cost of new knowledge in economic systems. Drawing on a conceptual framework, the Information Space or I-Space to explore how the uncontrollable diffusibility of knowledge relates to its degree of structure, we deploy an agent-based modelling approach to explore the issue of IPRs. We take the ability to control the diffusibility of knowledge as a proxy measure for an ability to establish property rights in such knowledge. Second, we take the rate of obsolescence of knowledge as a proxy measure for the degree of turbulence induced by different regimes of technical change. Then we simulate the quantity and cost to society of new knowledge under different property right regimes.

This paper explores the issue of a simultaneous reduction in tariffs at different stages of a vertically related market where each stage is oligopolistic. When vertically related markets are characterized as a successive oligopoly, reducing tariffs by an equivalent amount on upstream and downstream imports will have a differential effect on market access and hence profits at each stage as a result of a combination of horizontal and vertical effects. These differential effects have implications for the tariff structure post‐trade reform.  相似文献

Traditionally, consumers used the Internet to simply expend content: they read it, they watched it, and they used it to buy products and services. Increasingly, however, consumers are utilizing platforms—such as content sharing sites, blogs, social networking, and wikis—to create, modify, share, and discuss Internet content. This represents the social media phenomenon, which can now significantly impact a firm's reputation, sales, and even survival. Yet, many executives eschew or ignore this form of media because they don’t understand what it is, the various forms it can take, and how to engage with it and learn. In response, we present a framework that defines social media by using seven functional building blocks: identity, conversations, sharing, presence, relationships, reputation, and groups. As different social media activities are defined by the extent to which they focus on some or all of these blocks, we explain the implications that each block can have for how firms should engage with social media. To conclude, we present a number of recommendations regarding how firms should develop strategies for monitoring, understanding, and responding to different social media activities.  相似文献

This article introduces a newly discovered household budget data set for 1904. We use these data to estimate urban poverty among working families in the British Isles. Applying Bowley's poverty line, we estimate that at least 23 per cent of people in urban working households and 18 per cent of working households had income insufficient to meet minimum needs. This is well above Rowntree's estimate of primary poverty for York in 1899 and high in the range that Bowley found in northern towns in 1912–13. The skill gradient of poverty is steep; for instance, among labourers' households, the poverty rates are close to 50 per cent. Measures of the depth of poverty are relatively low in the data, suggesting that most poor male-headed working households were close to meeting Bowley's new standard.  相似文献

This paper estimates the degree of risk aversion from one of the most popular TV gameshows ever. The format of the show is straightforward; it involves no strategic decision making; we have a large number of observations; and the prizes are cash, which is paid immediately and covers a large range: from £100 up to £1 million. We provide non‐parametric estimates of the utility function and then we test some parametric restrictions. We find that, although the restriction to CRRA utility is statistically rejected, a log function approximates the utility function quite well over a large range of potential winnings.

This paper proposes a monitoring framework to be used during the planning stage for a sports mega-event. The research identifies a lack of monitoring and evaluation studies during the development stage for sports mega-events. Importantly, it notes the absence of research which evaluates an event systematically from the outset of the process and from the perspectives of host residents and event planners. The framework was developed on the basis of the philosophical approach of pragmatism; it focused on a sustainable development perspective, and it was applied to a case study of the Kaohsiung 2009 World Games. A survey of the views of 606 host residents about the potential impacts of the event revealed that the respondents tended to show higher levels of agreement on the host benefits. The results of 38 interviews with various stakeholders indicated big gaps in both the city's long-term development aspirations and the Games themselves and also in the event strategies adopted. Using this information, key sustainability issues can be identified and monitored during the event planning stage so that the desirable outcomes of events can be enhanced and then sustained in the longer term.  相似文献

Stebbins (1992) has suggested that the ‘profit hypothesis’, whereby the perceived benefits of taking part in an activity exceed the perceived costs, can be used to explain continued engagement in serious leisure activities. This argument, however, fails to explain the continued participation in such activities where the costs to the individual seem to exceed the rewards. This paper adopts a social identity perspective to identify and demonstrate the role of four compensatory behaviours – in-group favouritism, out-group derogation, unrealistic optimism, and voice – in ensuring continued participation in serious leisure. Such behaviours are described in the context of one particular serious leisure activity – that of football fandom – to explain why engagement in such an apparently unrewarding activity is maintained. A model of serious leisure participation is presented based upon these behaviours  相似文献
