Consider an auction in which one potential buyer wishes to participate, but the other potential buyer would rather the bidding not start. However, once bidding starts, the reluctant firm participates (submits “bluff bids”) simply to make the eventual winner pay more. This incentive exists when the marginal effect of the winning bid is to increase a rival's profit. In 2004, AT&T Wireless placed itself for sale in an English auction. Some predicted Vodafone would make bluff bids (to make Cingular pay more. Students experience this sort of activity in the game that this article describes. Students also learn that bluff bidding affects profits of the firms involved and therefore has important implications for stock prices of participating firms.  相似文献

Those who do not understand history are condemned to repeat it. The current discussion of cross-subsidies by the RBOCs threatens to reiterate all of the confusions of pre-divestiture discussions of AT&T's presumed cross subsidies. More careful analysis of current conditions reveals that the RBOC's competitive activities are not being cross subsidized out of the local rate base. If they are being subsidized, the subsidies come from the IX carriers.  相似文献

Using data on AT&T intrastate toll prices, this study examines the effect of changing regulatory practices and increased competition on AT&T pricing behavior in the intrastate long-distance telecommunications industry. The results suggest that, with some qualification, the price of AT&T telephone service is lower in states which have the longest history of departure from rate-of-return regulation. Moreover, the regulatory climate has a far more significant effect on AT&T prices than does competition. The paper outlines several possible explanations for these results.  相似文献

The present study examines the factors affecting the market share of the dominant firm in long-distance telecommunications, AT&T. A theoretical model is specified which includes competing long-distance rates (e.g., those of MCI and U.S. Sprint), price-cap regulation and advertising expenditures as determinants of the dominant firm's market share. Using intercity long-distance carrier charges for 1984–1994, this study points out the importance of AT&T's own rate structure, those of its major competitors, and government regulations in determining AT&T's market share over time.  相似文献

The process aimed at discovering new ideas is an economic activity the returns from which are intrinsically uncertain. We extend the neo-Schumpeterian growth framework to investigate the role of strong uncertainty in the innovative process. In particular, we postulate that, when deciding upon R&D efforts, investors hold ‘ambiguous beliefs’ about the exact probability of arrival of the next vertical innovation, and that they face ambiguity via the α −MEU decision rule (Ghirardato et al., J Econ Theory 118:133–173, 2004). Along the balanced growth path, the higher the agent’s ambiguity aversion (α), the lower the R&D efforts and the economic performance. Consistent with cross-country empirical evidence, this causal mechanism suggests that, together with the profitability conditions of the economy, different ‘cultural’ attitudes towards ambiguity may help explain the different R&D efforts observed across countries.  相似文献

This paper examines whether the ‘cross ownership’ of wireline and wireless communications carriers is socially beneficial or harmful, and therefore should be allowed or regulated. We analyze a generic model of cross ownership of the firms which produce different but inter-related services. We show that, first, if both of the wireline and wireless industries are monopolistic, cross ownership results in social gains when the two services are complements, and social losses when they are substitutes. Secondly, if the wireless industry is sufficiently competitive, there’s little or no welfare loss from cross ownership. Finally, we briefly address the effect of network externality on the welfare consequences of cross ownership.  相似文献

Regulatory decisions often must be made in an atmosphere of uncertainty, and arguments presented by the affected parties frequently add to, rather than resolve, that uncertainty. Here, we examine several of the deregulatory decisions affecting the long-distance market that were rendered by the FCC over the two-decade period following the divestiture of AT&T. Our purpose is to provide empirical evidence relevant to some of the arguments regarding market conditions that were presented during that period. Findings suggest that some of the more prominent allegations are not supported by the data.   相似文献

R&D investment is enterprises’ strategy based on the market demand on innovative products and its production capacity for them. Enlarging market demand would spur the enterprises’ R&D input and the enhancement of technology state in production ability could have a complex effect on less developed countries’ R&D expenditure. With the measurement of China’s technology state compared to the United States and Japan, this paper explores with the state space model the dynamic effects of determinants on China’s R&D expenditure with the data during 1987–2006. The result illustrates that the growing national income, a proxy of domestic market demand, impedes the further R&D investment in China due to the enormous demand for necessities dominated by lower income class, and the income inequality is the major incentive for R&D investment via the higher pricing on the wealthy group, and that the improvement of technology state reduces the innovation risk and plays an important role in stimulating R&D expenditure.   相似文献

In The Economics of Rights, Co-operation and Welfare (1986), Robert Sugden follows the tradition from Thomas Schelling and David Lewis in ascribing a central role to the notion of salience within his theory of convention. However, against this, Bruno Verbeek (Instrumental rationality and moral philosophy, Kluwer, Dordrecht, 2002) has argued that an empirically adequate notion of salience may not be incorporated into a generic account of convention without circularity obtains. This paper examines Verbeek’s argument against a background of experimental as well as theoretical work on coordination problems. It finds that the argument fails to consider at least two candidate theories of salience that may be incorporated into the theory of convention without circularity: cognitive hierarchy theory that iterates Sugden’s notion of psychological salience and Schelling salience. Thus, in the end Verbeek’s criticism of the role ascribed to salience in theories of convention may be dismissed, though its discussion draws a fruitful perspective.  相似文献

This paper examines Robert Heilbroner’s 1950 article in Harper’s Magazine on poverty in the USA. It argues that this piece was the first attempt to raise popular concerns about poverty in the USA after World War II, and in many ways sought to do what John Kenneth Galbraith’s The Affluent Society and Michael Harrington’s The Other America accomplished. Heilbroner was not successful in bringing the issue before poverty to public attention because he wrote at a time of great economic growth and at a time before TV brought images and ideas to a large fraction of the American public. He also wrote in a very conservative era, where McCarthyism reared its ugly head and where calls to eradicate poverty were met with intimations of a Communist conspiracy.

This paper reexamines broadly. from the standpoint of innovation, the arguments for vertical integration in the U.S. telecommunications industry in light of structural change since the breakup of the Bell System. While basic and applied research became the casualty of the 1984 breakup and the 1995 AT&T split, there is no evidence that the pace of innovative activity and productivity has slowed. Evidence from R&D and patent data suggests some acceleration of innovative activity. However. the service segment of the industry ceased to be the center of technological innovation. The source of future innovation seems to lie in the telecommunications and Internet equipment firms and independent software firms. The emergence of the competitive stand-alone software industry, combined with a trend towards open operating systems and customer demand for greater flexibility, and growing substitution of technology alliances for in-house R&D appear to have undermined the case for vertical integration in the telecommunications industry. From the standpoint of business strategy, the question of whether a firm like AT&T, notwithstanding its huge investments in cable facilities, can develop distinctive and sustainable capabilities through horizontal expansion and ubiquity and one-stopshopping marketing alone remains open.  相似文献

Despite recent advances in the Evolutionary and Systems Perspectives to Economic Change (SI), confusion still exists about how to apply it to the design and implementation of Innovation & Technology Policy (ITP) in concrete settings. Since the ‘Normative’ aspects of SI are framed in terms so general to make them insufficient or inadequate as guides and tools for actual policymaking, a presumption exists that additional theoretical and conceptual knowledge is required. Thus a major objective of this paper is to contribute to the development of a realistic and ‘grounded’ theoretical framework for Technology and Innovation Policy which is particularly relevant both for the promotion of Business Sector R&D and of hi tech (especially IT) industries in Top Tier and other Industrializing Economies. A second objective is to contribute directly to the capability of successfully applying this conceptual framework in concrete policy settings. Rather than justifying ITP the paper focuses on characterising and applying “Salient Normative Principles or Themes” of the SI perspective to ITP. Several concrete examples are given and the notions of Policy Process, (Country) Program Portfolio Profile and Policy Environment are introduced.  相似文献

In this paper, I examine the optimal patent shape in an economy in which R&D firms innovate and imitate, households face non-diversifiable risk and there is externality in production and R&D. With non-diversifiable risk, a household’s consumption and investment decisions are interlinked. This economy contains industries of two kinds: monopoly industries with an innovator only, and duopoly industries with an innovator and an imitator. I define patent length as the expected time in which an innovation is imitated, and patent breadth as the innovator’s profit share in an industry after a successful imitation. The government can control patent length by the requirements for accepting a substitute for a patented good, and patent breadth by imposing compulsory licensing and royalties for the patentee after a successful imitation. I show that the stronger the externality in production relative to R&D is, the slower the optimal growth rate, the larger the optimal proportion of duopoly industries, and the longer and narrower the optimal patent.  相似文献

By using HS classification, the author has divided total agricultural products into 24 categories. The paper calculated the G-L intra-industry trade index, Brülhart marginal intra-industry trade index, and Thom & McDowell marginal industry trade index for each type of agricultural products during the period from 1996 to 2005 in China. The conclusion shows the overall level of agricultural intra-industry trade is relatively low, and Brülhart index indicates China’s agricultural products decades of improvement mainly from inter-industry trade, at the same time Thom & McDowell index shows that China’s agricultural intra-industry trade growth is mainly from the growth of vertical intra-industry trade. __________ Translated from Guoji maoyi wenti 国际贸易问题 (Journal of International Trade), 2008, (1): 14–20  相似文献

Based on resource curse hypothesis, this paper carries out an econometric analysis on the relationship and its transmission mechanism between energy exploitation and economic growth with cross-province panel data over 1991–2006. Results reveal that there is the significantly negative correlation between energy exploitation and economic growth, which indicates since the 1990s, the resource curse effect from energy exploitation has appeared evidently; though, before the implementation of the Western development strategy, energy exploitation acted negatively on opening degree, S&T innovation and human capital input, the effect was yet uncreated. However, after the implementation of the strategy, the effect emerged evidently as a result of the enhanced negative effect of energy exploitation on S&T innovation and human capital input. Moreover, further tests indicate that energy exploitation impeded economic growth mainly through three indirect transmission channels: The crowding-out effect towards human capital input and S&T innovation, and the weakening of institution aroused by rent-seeking and corruption. And among them, human capital input is the strongest transmission factor. __________ Translated from Jingji yanjiu 经济研究 (Economic Research Journal), 2008, (4): 147–160  相似文献

In many price-cap regulation plans, such as those of AT&T and British Telecom, a weighted average of the prices for multiple services (baskets) must not exceed a specified level. This analysis demonstrates that the weighting scheme most commonly employed is subject to intertemporal manipulation. This investigation provides specific demand conditions under which weight manipulation can arise, shows the manipulation to reduce social welfare, and proposes a simple alternative weighting scheme that is less prone to manipulation. The alternative weighting scheme can help in designing more effective price-cap plans, especially if new plans have longer terms than current ones.  相似文献

This paper investigates the relationship between parents’ education and children’s wage using two nationally representative data sets in China. Controlling for other things, both father’s and mother’s education are positively correlated with children’s wage. Nevertheless, returns to father’s education are lower in more market-oriented segments of the economy, including coastal regions, the non-state sector, and the later period of the reform era (post-1992), while the opposite is true for mother’s education. We argue that this new empirical evidence is consistent with the story that father’s education mainly indicates family connections useful for locating a better-paying first job, while mother’s education primarily captures unmeasured ability.  相似文献

This study measures the extent to which P2P file-sharing activities act as substitutes or complements to music purchases in markets for CDs. The paper breaks with the mainstream economics approach which dominates the music file-sharing discussion. Whereas such models assume relationships at the micro level (e.g. between file-sharing and purchases) based on observations made at the macro level, our evolutionary economics approach measures the direct effects using micro data representative of the Canadian population. The behavioral incentives underpinning free music downloading, novel to this paper, are the multiple effects of: ‘unwillingness to pay’ (market substitution), ‘hear before buying’ (market creation), ‘not wanting to buy a whole album’ (market segmentation), and ‘not available in the CD format or on electronic pay-sites’ (market creation). Although the two first mentioned incentives significantly influence CD album purchases—i.e. there is a negative and significant market substitution effect and a positive and significant market creation effect—on the whole, these two effects ‘cancel’ one another out, leading to no association between the number of P2P files downloaded and CD album sales.  相似文献

It is recommended for economists to examine China’s Urban-Rural disparity from the perspective of transaction efficiency, in that it can provide us with a systematic explanation to both the cases of different countries and development stages. China’s Urban-Rural disparity is special and virtually a demonstration of its special transaction efficiency structure. Exploration of China’s Urban-Rural disparity from such perspective indicates that, different from those in countries with a market economy, China’s case involves many exogenous and contrived factors. Therefore, the solutions are to improve the whole transaction efficiency in the economy, which includes eliminating its regionally unfavorable policies and institutions, and enforcing more favorable and regionally balanced institutional reforms. __________ Translated from Fudan Journal (复旦学报, Social Science Edition), 2006, (1) (in Chinese)  相似文献

Almost every week national elections are held somewhere in the world. Many more elections take place at federal and local levels of government. Surely, these are important events to many of us. This thesis aims at providing a better understanding of why and how people vote in elections. Three original modifications of Palfrey and Rosenthal’s (1983) participation game are used to study voter turnout theoretically and experimentally.1 In the basic game, each voter supports (i.e., prefers) one of two exogenous candidates and privately decides between voting at a cost and abstaining (without costs). The candidate who receives more votes wins the election (ties are broken randomly) and each supporter of this candidate receives an equal reward, independent of whether or not she voted. The first study (published in the American Political Science Review 100, pp. 235–248) analyzes the effects of social embeddedness on turnout, assuming that voters may be influenced by observing the decisions of other voters around them (e.g., a family or working place). Our experimental results show that the social context matters: this information increases turnout by more than 50%. The increase is greater when neighbors support the same candidate rather than when they support opponents. The second study investigates the effects of public opinion polls on voter turnout and welfare. Poll releases resolve uncertainty about the level of support for each candidate caused by `floating’ voters, whose preferences change across elections. This information increases turnout in the laboratory by 28–34%, depending on the fraction of floating voters in the electorate. If polls indicate equal levels of support for both candidates—in which case aggregate benefits for society are not affected by the outcome—welfare decreases substantially due to costs from excessive turnout. In the final study, elections are preceded by the competition between two candidates: they simultaneously announce binding policy offers in which some voters can be favored at the expense of others through inclusion and exclusion in budget expenditure (Myerson 1993).2 We observe that policy offers include 33% more voters—yielding a smaller budget share for each—when voting is compulsory rather than voluntary. Moreover, we find evidence of political bonds between voters and long-lived parties. Overall, in all three experiments many subjects strongly react to economic incentives (i.e., benefits, costs, and informational clues), often in line with what is observed outside of the laboratory.
