The consensus that emerges from the current research on the linkage between securitized and direct investment in real estate is that direct (private) real estate returns play a relatively minor role in the real estate investment trust (REIT) return generating process. However, this result may at least partially be due to the coarseness of the measures of direct real estate returns or the relatively short return horizons used in previous studies. This study takes a different and unique perspective. Unlike earlier studies we do not use aggregated, average appraisal based returns on direct real estate investment. Instead, we use the MIT TBI indexes, which are transaction based price indexes, available both on the aggregate and sub-index levels. We find that the relation between REIT and direct real estate returns appears to be stronger at longer horizons. More specifically, using a cointegration framework, we find robust evidence that REITs and the underlying real estate are related and that they share a long run equilibrium. Interestingly, we find that both REITs and direct real estate returns adjust towards this long run relationship. When we examine property type level data we find similar results. 相似文献

There is little doubt that Corporate Social Responsibility (CSR) is now a global concept and a prominent feature of international
business, with its practice localised and differing across countries. Despite the growing body of research focussing on CSR
in developing countries, there is dearth research on CSR institutionalisation in African countries. Drawing on institutional
theory (IT), this article examines the focus and form of CSR practice of companies in Kenya. It is evident from our findings
that the nature and orientation of CSR differ across companies with operations only in Kenya and those headquartered abroad
or with international operations. Significantly, firm-related drivers such as public relations and performance, as well as
global institutional pressures explain the focus and form of CSR in Kenya. This article concludes that for the institutionalisation
of CSR in Kenya, attention must be paid to conditions that stifle CSR uptake such as lack of government regulations, and the
government’s capacity and commitment to enforce regulation. The establishment of functional CSR institutions and a vibrant
civil society that advance civil regulation ought to be encouraged. 相似文献

What Can Acreage Allocations Say about Crop Supply Elasticities? A Convex Programming Approach to Supply Response Disaggregation

This article has two goals. The first is to extend previous results regarding calibration of land‐constrained programming models of agricultural supply against supply elasticities to the general case of multiple constraints. The second goal is to demonstrate how the resulting calibration conditions can be used as a source of identification to disaggregate crop supply elasticities down to the level at which static information on acreage allocations is available. We propose an information‐based disaggregation algorithm to systematically generate regionalised elasticities from a single prior, and provide an empirical illustration. 相似文献

In recent years scholars have begun to focus on the consequences of individuals' exposure to civil war, including its severe health and psychological consequences. Our innovation is to move beyond the survey methodology that is widespread in this literature to analyze the actual behavior of individuals with varying degrees of exposure to civil war in a common institutional setting. We exploit the presence of thousands of international soccer (football) players with different exposures to civil conflict in the European professional leagues, and find a strong relationship between the extent of civil conflict in a player's home country and his propensity to behave violently on the soccer field, as measured by yellow and red cards. This link is robust to region fixed effects, country characteristics (e.g. rule of law, per capita income), player characteristics (e.g. age, field position, quality), outliers, and team fixed effects. Reinforcing our claim that we isolate the effect of civil war exposure rather than simple rule breaking or something else entirely, there is no meaningful correlation between our measure of exposure to civil war and soccer performance measures not closely related to violent conduct. The result is also robust to controlling for civil wars before a player's birth, suggesting that it is not driven by factors from the distant historical past. 相似文献

Consumers assess the credibility of online product reviews to guide their purchase decisions. However, little is known about how consumers determine the credibility of online product reviews. This article examines the effect of the level of detail in a product review and the level of reviewer agreement with it on the credibility of a review and consumers' purchase intentions for search and experience products. Overall, the results indicate that more credible reviews lead to higher purchase intentions. Interestingly, the findings also demonstrate that consumers determine the credibility of a review differently for search and experience products. For search products, consumers deem online reviews to be more credible when the reviews contain detailed information about the product. However, for experience products, consumers determine the credibility of a review by assessing the level of reviewer agreement with a review. The lack of diagnosticity of detailed information in online reviews of experience products is attributed to the idiosyncratic nature of experiences. Implications for research and practice are discussed. 相似文献
