Global leaders agree on the need to substantially decarbonize the global economy by 2050. This paper compares potential costs associated with different policy pathways to achieve tourism sector emission reduction ambitions (?50% by 2035) and transform the sector to be part of the mid-century decarbonized economy (?70% by 2050). Investment in emissions abatement within the tourism sector, combined with strategic external carbon offsets, was found to be approximately 5% more cost effective over the period 2015–2050 than exclusive reliance on offsetting. The cost to achieve the ?50% target through abatement and strategic offsetting, while significant, represents less than 0.1% of the estimated global tourism economy in 2020 and 3.6% in 2050. Distributed equally among all tourists (international and domestic), the cost of a low-carbon tourism sector is estimated at US$11 per trip, equivalent to many current travel fees or taxes. Exclusive reliance on offsetting would expose the sector to extensive and continued carbon liability costs beyond mid-century and could be perceived as climate inaction, increasing reputational risks and the potential for less efficient regulatory interventions that could hinder sustainable tourism development. Effective tourism sector leadership is needed to develop a strategic tourism policy framework and emission measurement and reporting system. 相似文献

The literature on organizational learning asserts that external learning is often limited geographically and technologically. We scrutinize to what extent organizations acquire external knowledge by accessing external knowledge repositories. We argue that professional service firms (PSFs) grant access to nonlocalized knowledge repositories and thereby not only facilitate external learning but also help to overcome localization. Focusing on patent law firms, we test our predictions using a unique dataset of 544,820 pairs of European patent applications. Analyzing patterns of knowledge flows captured in patent citations, we find that accessing a PSF's repository facilitates the acquisition of external knowledge. As the effect is more pronounced for knowledge that is distant to a focal organization, we conclude that having access to a knowledge repository compensates for localization disadvantages.

The rejection of the treaty establishing a European constitution by French and Dutch voters has thrown the EU into a deep crisis. What developments in the EU contributed to these referenda results? What consequences are to be drawn for the continuation of integration and the integration goal, the governance of the EU-25 and the further planned enlargements? What flaws are there in the present draft constitution and how can these be dealt with? 相似文献

A major challenge in developing an e-negotiation system (ENS) is that the system should fit into the context which varies
with negotiation cases. To mitigate context dependency, we propose to separate e-negotiation protocols from ENS and adopt
a component-oriented approach. In this paper, we present a framework for e-negotiation protocols that implements this approach.
The framework has been tested by developing several ENSs of which two had been tested in laboratory negotiation experiments
with more than 100 participants. 相似文献

Assuming that macroeconomic policies are directed by distinct monetary and fiscal policy makers who cannot commit to future actions, we reassess the implications of monetary conservatism and fiscal impatience in a setting with nominal government debt. For environments where a non-negative steady state level of government debt (assets) emerges in the absence of conservatism and impatience, monetary conservatism induces accumulation of a higher stock of liabilities (assets) and has adverse (positive) welfare implications. This result obtains irrespectively of the degree of fiscal impatience and questions the unambiguous desirability of monetary conservatism traditionally found in the literature. 相似文献

In this paper we identify risk factors for Asia-focused hedge funds through a modified style analysis technique. Using an Asian hedge fund index, we find that Asian hedge funds show significant positive exposures to emerging equity markets. For both a static and rolling period style analysis, our model provides a high explanatory power for returns of the considered hedge fund index. We further conduct a Value-at-Risk analysis using the results of a rolling window style analysis as inputs. Our findings suggest that the considered parametric models outperform a simple historical simulation that is purely based on past return observations. 相似文献
