Despite a lot of restructuring and many innovations in recent years, the securities transaction industry in the European Union is still a highly inefficient and inconsistently configured system for cross-border transactions. This paper analyzes the functions performed, the institutions involved and the parameters concerned that shape market and ownership structure in the industry. Of particular interest are microeconomic incentives of the main players that can be in contradiction to social welfare. We develop a framework and analyze three consistent systems for the securities transaction industry in the EU that offer superior efficiency than the current, inefficient arrangement. Some policy advice is given to select the ‘best’ system for the Single European Financial Market. 相似文献

In this paper, we study consumers with limited memory and examine the effects of their price categorization on the pricing strategies of competing firms. The valuations of consumers are assumed to be heterogeneous. We find that it is possible to observe price dispersion even when each firm charges a single price if the consumers categorize prices non‐optimally. Moreover, we demonstrate that the likelihood of a price dispersion outcome is reduced when consumers with limited memory set up the price categories optimally. These findings suggest that the consumers' limited memory and their sub‐optimal behavior, that is, their inability to choose price categories optimally can be a reason for observed price dispersion. 相似文献

Insights from contemporary psychology can illuminate the common psychological processes that facilitate unethical decision making. I will illustrate several of these processes and describe steps that may be taken to reduce or eliminate the undesirable consequences of these processes. A generic problem with these processes is that they are totally invisible to decision makers – i.e., decision makers are convinced that their decisions are ethically and managerially sound. 相似文献

Recent research has emphasised that an increasing number of enterprises need computation environments for executing HPC (High Performance Computing) applications. Rather than paying the cost of ownership and possess physical, fixed capacity clusters, enterprises can reserve or rent resources for undertaking the required tasks. With the emergence of new computation paradigms such as cloud computing it has become possible to solve a wider range of problems due to their capability to handle and process massive amounts of data. On the other hand, given the pressing regulatory requirement to reduce the carbon footprint of our built environment, significant researching efforts have been recently directed towards simulation-based building energy optimisation with the overall objective of reducing energy consumption. Energy optimisation in buildings represents a class of problems that requires significant computation resources and generally is a time consuming process especially when undertaken with building simulation software, such as EnergyPlus. In this paper we present how a HPC based cloud model can be efficiently used for running and deploying EnergyPlus simulation-based optimisation in order to fulfil a number of objectives related to energy consumption. We describe and evaluate the establishment of such an application-based environment, and consider a cost perspective to determine the efficiency over several cases we explore. This study identifies the following contributions: (i) a comprehensive examination of issues relevant to the HPC community, including performance, cost, user perspectives and range of user activities, (ii) a comparison of two different execution environments such as HTCondor and CometCloud and determine their effectiveness in supporting simulation-based optimisation and (iii) a detailed performance analysis to locate the limiting factors of these execution environments. 相似文献

In recent years stock exchanges have been increasingly diversifying their operations into related business areas such as derivatives trading, post-trading services and software sales. This trend can be observed most notably among profit-oriented trading venues. While the pursuit for diversification is likely to be driven by the attractiveness of these investment opportunities, it is yet an open question whether certain integration activities are also efficient, both from a social welfare and from the exchanges’ perspective. Academic contributions so far analyzed different business models primarily from the former perspective, whereas there is only little literature considering their impact on the exchange itself. By employing a panel data set of 28 stock exchanges for the years 1999–2003, we seek to shed light on this topic by comparing the technical efficiency and factor productivity of exchanges with different business models. Our findings suggest that exchanges that diversify into related activities are mostly less efficient than exchanges that remain focused on the cash market. In particular, we find no evidence that vertically integrated exchanges are more efficient. However, they seem to possess a substantially stronger factor productivity growth than other business models. We presume that integration activity comes at the cost of increased operational complexity which outweigh potential synergies between related activities and therefore leads to technical inefficiencies. Our findings contribute to the ongoing discussion about the drawbacks and merits of vertical integration. 相似文献

This paper attempts to clarify the meaning of the term ‚professional’ in its current use in our daily lives, mainly by making
use of Weber’s discussion of the Protestant work ethic and rationalization. Identifying professionalism primarily as a particular
lifestyle, it questions whether professionalism is a virtue to be encouraged or an alienated way of life. Rather than conclusively
answering this question in the affirmative or negative, it contends that professionalism is an evolving concept, and endeavors
to capture and formulate a favorable understanding of it which would foster less alienating and more fulfilling ways of doing
business. It concludes by observing structural similarities between alternative managerial approaches and different conceptualizations
of professionalism.

Increased and active involvement of multinational corporations in the promotion of social welfare, in developing countries
in particular, through the facilitation of partnerships and cooperation with public and nonprofit sectors, challenges the
existing framework of our social and political institutions, the boundaries of nation-states, the distinction between the
private and public spheres of our lives, and thus our freedom. The blurring of certain distinctions, which ought to be observed
between the political and the economic is most manifest in the gradual saturation of the field of business ethics with rights-based
arguments and analyses. In this article, I first argue against endorsing positive rights as having the same status as negative
rights, and then try to demonstrate that, with the transportation of ‹rights talk’ into business ethics, the dangers of conflating
positive and negative rights are superimposed on the dangers of conflating the private and the political. I conclude by presenting
my own stance on the debate on what our basic institutionally sanctioned rights should be, and what the corresponding duties
of multinational corporations really are. 相似文献

Peasants,bandits, and state intervention: The consolidation of authority in the Ottoman Balkans and Southern Italy 下载免费PDF全文

This paper explores the role of bandits and state intervention in the Ottoman Balkans and Southern Italy in the 19th century by using archival documents. I argue that the states may react similarly and radically when their authority is challenged in the periphery. The Ottoman Empire and the Kingdom of Italy developed the same forms of state intervention to fight against the bandits, even though these two states had fundamentally different political, cultural, and socio‐legal structures. I present three different forms of state intervention: (i) victim‐centred state intervention; (ii) security‐centred state intervention; and (iii) authority‐centred state intervention. These three forms consolidated the state's authority while making the two states both fragile and dependent on other social agencies in the long term. I further claim that consolidation of the state's authority manifests the paradox of state intervention and creates more vulnerabilities in traumatic geographies. 相似文献

The main aim of this paper is to explore the competition between traditional fixed line and mobile services across Eastern Europe and the Former Soviet Union. Whilst there have been some pioneer studies in the US, empirical evidence for other regions is very limited. Transition countries witnessed important trends in the mobile segment of the market. First, mobile penetration rates have been growing at exponential rates, whereas fixed line penetration rates have at best stagnated. The present analysis is based on empirical evidence based on country level data and case studies, as well as enterprise level data based on major surveys that the EBRD and the World Bank undertook in 2002 across all transition economies. Econometric analysis at the enterprise level shows some interesting results, including evidence of strong network externalities and fixed to mobile substitution effects at the country level. 相似文献
