Evidence from firms in 47 countries shows that companies with political connections have higher leverage and higher market shares, but they underperform compared to nonconnected companies on an accounting basis. Differences between connected and unconnected firms are more pronounced when political links are stronger. Differences also vary depending on the level of corruption and the degree of economic development in individual countries. 相似文献

iPhone Siri demonstratively introduced natural language processing. Still a gadget, the idea revived one of the old promises of computers as personal assistants. Does it have the potential of fulfilling the already burgeoning imagination related to this promise? The authors believe that, while still dependent on the evolution of artificial intelligence, the virtual assistant may find support in the already maturing technologies of augmented reality and, more important, in the changing global network with the semantic web, Internet of things and geo-location. Bluntly speaking, its feasibility and acceptability may not even have to wait for the promised IBM computer with human brain capabilities, but rather build on a more friendly interaction with the Google search engine.The article provides a narrative scenario of the deep economic and social transformations and even turbulence that the so called imaginary friend may produce. Not discarding, but creatively integrating some of the archetypes of futuristic literature, the story positions these entities as the foreground of a deep integration of networks, with the added turmoil caused by economic interests that go beyond individuals’ sense-making capacity.This article is one of the follow-ups of the international foresight workshop “Crazy futures” coordinated by Ziauddin Sardar and George Cairns in a small resort on the Danube Delta in July 2011, a workshop organised as part of the project Quality and Leadership for Romanian Higher Education. 相似文献

Frequent flyer programs (FFPs) may allow airlines to exercise market power on routes that depart from airports at which they are dominant. Prior research, however, has not disentangled the effects of FFPs from other advantages that dominant airlines may possess. I exploit variation in the extent and scope of U.S. airlines' FFP partnerships with international carriers to evaluate the economic impact of enhancements to FFPs. The results indicate that enhancements to an airline's FFP are associated with increases in its demand on specifically those routes that depart from airports at which it is dominant. 相似文献

Deriving and Testing Efficient Estimates of WTP Distributions in Destination Choice Models 总被引:1,自引:0,他引:1
Estimation of welfare measures is often a dominant driver in the empirical literature on nonmarket valuation. To this end,
qualitative choice models based on random utility theory have been widely employed in outdoor recreation studies. A frequent
goal of applied studies has been the estimation of welfare changes associated with site attribute changes at recreation sites
in order to inform regulatory policy and resource management. We review the evolution of the methodology of random utility
theory in this field with a focus on taste heterogeneity models and then focus on the recent proposal of specifying utility
in the WTP-space (Train K, Weeks M (2005) Discrete choice models in preference space and willing-to-pay space. In: Scarpa
R, Alberini A (eds) Applications of simulation methods in environmental and resource economics, chapter 1. Springer, Dordrecht,
pp 1–16). Our empirical application is on outdoor alpine recreation data. We emphasize the efficiency and direct testing that
using the maximum simulated likelihood estimator affords to practitioners using the WTP-space approach, and illustrate these
with examples. 相似文献

Animal farming exceeds all forms of transport in terms of global greenhouse gas (GHG) emissions. Despite the implications of the seriousness of addressing animal farming in relation to mitigating the effects of GHG emissions, to date, the relationship between consumer behaviour and climate change has tended to neglect the role of animal foods. This paper reports on a pilot study in which six UK households were ‘shadowed’ to facilitate the investigation of the relationship between animal food practices and environmental practices, as they emerge in day‐to‐day life. Results indicate that most participants make no connection between the two issues at present, in terms of awareness or practice. However, animal foods do have an ambiguous and complex status in most participants' food practices; for instance, being viewed as problematic for reasons of health or animal welfare. This finding suggests that further research is needed into the potential for raising awareness of the link between animal‐based foods and climate change. This might have a role to play in shifting food practices towards more plant‐based, less GHG intensive, foods. 相似文献

This article provides an exploratory analysis from the perspective of the port operators of the factors that determine the competitiveness of fuel supply at the ports of the Gibraltar Strait (Bay of Algeciras, Gibraltar and Ceuta). The methodology is based on interviews and questionnaires focused on public and private institutions involved in the port services. The results reveal that fuel prices and geographical advantage are the two main factors seen by Gibraltar Strait port operators as influencing shipping company choice of bunkering port. In order of importance, other identified factors related to the cost and quality of services, including port tariffs, supply waiting time, service rates, simplicity of crew changing, presence of restrictive environmental regulations and customs strictness. 相似文献

The euro illusion is a transient phenomenon that consists of currency-related asymmetries in the intuitive judgment of product
prices made by consumers. The results of a cross-country study in the third year after the introduction of the euro show a
strong price estimation asymmetry in a country with an extreme exchange rate (Italy) and a weaker effect in a country in which
the nominal values of the new and the old currency are much closer (Ireland). These results rule out proposed explanations
of the euro illusion in price estimation that assume the sole influence of plausible anchors (reference prices stored in memory
within the plausible price range), supporting instead accounts also endorsing the role of implausible anchors (reference prices
outside the plausible price range). Beyond contributing to our theoretical understanding of the euro illusion, this research
starts to unveil the interplay between structural factors (i.e., the currency exchange rate) and psychological mechanisms
that produce long-lasting difficulties for consumers after a monetary changeover.

Evidence is provided on the PPP hypothesis using a sample of 50 Spanish cities for a long time period through the application of panel data unit root tests. Although results suggest non-rejection of the PPP, short-run deviations – as measured by half-lives – indicate that real factors might be causing a slow rate of convergence to a common price index, even in highly integrated economies. 相似文献

This study analyses the factors triggering insider trading profitability. Since there is not much evidence on this topic in
the continental-European context, we focus on the Spanish stock market. Our findings show that the main relevant factors (the
timing ability of the insider, the transparency of the transaction and the level of free cash flow of the firm) are related
to insiders’ opportunities behaviour, motivated by the lack of either managerial control within the firm or enforcement of
insider trading regulation. The level of ownership concentration, the spread and the interaction between the size and the
transparency of the transaction are other relevant factors, some of them tested for the first time in the insider trading
literature.
