It is well known that the Nash equilibrium in network routing games can have strictly higher cost than the optimum cost. In Stackelberg routing games, where a fraction of flow is centrally-controlled, a natural problem is to route the centrally-controlled flow such that the overall cost of the resulting equilibrium is minimized.We consider the scenario where the network administrator wants to know the minimum amount of centrally-controlled flow such that the cost of the resulting equilibrium solution is strictly less than the cost of the Nash equilibrium. We call this threshold the Stackelberg threshold and prove that for networks of parallel links with linear latency functions, it is equal to the minimum of the Nash flows on links carrying more optimum flow than Nash flow.Our approach also provides a simpler proof of characterization of the minimum fraction that must be centrally controlled to induce the optimum solution. 相似文献

This paper endogenises the internal organisation of competitive firms in a simple general equilibrium framework. The options are monitored teams, unmonitored teams motivated by collective performance pay, and self-employment. The choice of incentive scheme depends on market price and also affects price through its influence on output. As more people opt for self employment, pecuniary externalities increase the pressure on the rest to follow suit and Pareto rankable multiple equilibria arise. The conditions for a competitive equilibrium to be constrained efficient are restrictive and everyone may gain from policies limiting monitoring and self employment and from the imposition of entry taxes. 相似文献

The process of product replacement is a surprisingly neglected area of innovation. Its existence as an important corporate activity is known through prior research and anecdotal evidence. This study was designed to shed some light on the replacement activities which are conducted by large companies in Britain and America. The findings revealed a number of different approaches to product replacement and suggested that related activities can be understood (and measured) by seven distinct dimensions. 相似文献

Since 1978, when China announced its ‘open-door’ policy to pursue the country's long-term national goal, the Four Modernisations, more than 220,000 foreign funded ventures have been approved. By the end of 1994 some US$300 billion of contracted investment had been agreed and US$95 billion of utilized investment, making the country the most important recipient of foreign direct investment (FDI) in the developing world. This paper analyses the phenomenon of FDI in China. It examines the different forms and composition of FDI, reviewing its development since the early days of the ‘open-door’ policy and analysing its importance for Chinese domestic and export industries, as well as Western investor companies. Furthermore, the paper focuses on the world-wide sources of FDI in China and its distribution by both region and industry. Additionally, it reviews the existing research on FDI in China, emphasizing the investment mode of equity joint venture. 相似文献

This article explores the composition and geographies of individual wealth holding in England and Wales in the late nineteenth century. It draws on various forms of death duty records to determine the individual ownership of wealth including both personal property and real estate. By combining information on these different kinds of property, it is possible to explore how different strata of wealth holders accumulated specific forms of wealth at the time of their death. The article then examines how the composition of that wealth varied according to the wealth holder's location in the urban hierarchy and distance from London. It points out important geographical differences in both the scale and nature of wealth holding and raises questions about the implications of these findings. 相似文献

Export growth is seen by governments as being a key to economic recovery. In the United States, the Obama Administration pledged to double exports by the year 2015. To gain greater insights into exporting as an engine for growth, we look to export lenders to understand the contextual changes in export lending, as well as priorities in evaluating exporters. Findings from a study of export lenders on the lender referral list of the Export-Import Bank of the United States suggest that changes in the financial industry's structure over the last two decades, coupled with the economic recession, have motivated policy—at both the lending firm and governmental level—that hampers the ability of exporting to contribute to economic recovery. Further, the findings suggest that current lender policy encourages a focus on short-term returns rather than an exporter's long-term strategic position in the market. Lender preferences, in addition to governmental policies increasing regulation of the financial sector, place significant constraints on economic recovery. Thus, we call for key lender and governmental policy changes that could release industry constraints and unleash the export engine for economic recovery. 相似文献
