This study investigates whether culture plays a major role in determining the corruption levels of countries. The cultural dimensions of Hofstede’s model and the worldwide level of corruption provided by the Corruption Perceptions Index were used. A cross-country survey of 98 countries was conducted using ordinary least squares (OLS) regression. Three of the six main components of Hofstede’s model were found to have a significant influence on corruption, namely power distance, individualism-collectivism, and long- versus short-term orientation. National culture may explain the level of corruption in each of the countries. About half of the level of corruption in countries is explained by the national culture. Governments must acknowledge the role of culture in order to adopt the most appropriate policy decisions to fight corruption. 相似文献

New Zealand is the only country to date to have implemented forced ownership unbundling of electricity distribution from the
rest of the electricity supply industry (in 1998). This paper examines the impact of this policy on electricity prices, quality
of service and costs. We find that ownership unbundling did not achieve its objectives of facilitating greater competition
in the electricity supply industry but that it did lead to lower costs and higher quality of service. We suggest that this
experience indicates the potential benefits of ownership unbundling in Europe but also the danger of unintended consequences. 相似文献

Antitrust authorities have imposed firewalls between the previously separate divisions of newly vertically integrated firms
in several industries, to address concerns that access to horizontal rivals’ proprietary information may reduce competition.
This paper evaluates a specific antitrust concern by modeling the price effect of one seller’s learning its rival’s production
costs before bidding in a duopoly procurement contest. The results show that imposing a firewall as a condition for permitting
a vertical merger actually can lead to higher prices than if the flow of information were unimpeded, and they provide guidance
as to when this unintended outcome occurs. 相似文献

This paper measures the impact of the entry of large supermarkets on incumbents of various sizes. Contrary to the conventional
notion that big stores drive small rivals out of the market, data from Tokyo in the 1990s show that large supermarkets’ entry
induces the exit of existing large and medium-size competitors, but improves the survival rate of small supermarkets. These findings highlight the role of store size as an important dimension of product
differentiation. Size-based entry regulations would appear to protect big incumbents, at the expense of small incumbents and
potential entrants. 相似文献

Creativity is acknowledged to be important for economic growth and as an everyday life-skill, however several influential reports have suggested that education could do more to harness creative talent. Creative cognition literature suggests the lack of creativity is at least partly the result of ‘fixation’ (difficulty in generating novel ideas due to imagination being ‘structured’ by existing knowledge). This paper focuses on the secondary (students aged 11–16 years) design and technology (D&T) context in the UK. Here we examine whether teacher practice can contribute to fixation by focusing on one specific facet of teacher practice in D&T; the use of product analysis to inform the generation of creative design ideas. Data is drawn from the preliminary phase of a research and intervention project from interviews with D&T teachers (N = 14), students (N = 126) and lesson observations (N = 10) and an analysis of documents and student work. Product analysis is widely used at different points in design projects but, as is shown, in all cases current practice can lead to fixation, as thinking is constrained down specific paths and tasks are at best at procedural rather than comprehension level. The implications of these findings and tentative ways forward for practitioners are discussed. 相似文献

This study investigates what pupils aged 10–12 can learn from working with robots, assuming that understanding robotics is a sign of technological literacy. We conducted cognitive and conceptual analysis to develop a frame of reference for determining pupils’ understanding of robotics. Four perspectives were distinguished with increasing sophistication; “psychological”, “technological”, “function”, and “controlled system”. Using Lego® Mindstorms® NXT robots, as an example of a Direct Manipulation Environment, we developed and conducted a lesson plan to investigate pupils’ reasoning patterns. There is ample evidence that pupils have little difficulty in understanding that robots are man-made technological and functional artifacts. Pupils’ understanding of the controlled system concept, more specifically the complex sense-reason-act loop that is characteristic of robotics, can be fostered by means of problem solving tasks. The results are discussed with respect to pupils’ developing technological literacy and the possibilities for teaching and learning in primary education. 相似文献
