创新经济学将技术创新在企业、研究机构等经济体中的发展作为主要研究对象,企业家的创新同样也是增长的动力;对我国一些地区中小家族企业的调研表明,立足于新技术、新管理和创新人才的支持是加入世界贸易组织后企业创新的进展。本文结合实际材料,对这两方面的研究展开了分析。 相似文献

发展核电、开发利用核能充满复杂而多层次的价值矛盾,在巨大的生态与经济利益和风险之间.核电对生态环境及人类安全的威胁问题倍受社会各界的关注.并由此引发了一系列价值难题和伦理争论,成为影响核电发展的关键。核电的安全、可持续发展不仅仅是技术问题,还涉及一系列的伦理问题,要保证核电可持续发展并有益于生态环境保护且不损害人类利益,不能犯“技术决定论”的错误.必须辅之以伦理之轨。伦理之轨通过深入核电发展链的各个环节.对核电发展进行伦理价值观的批判和引导.参与战略选择使之得以规约.并保障核电发展有益于人类合的目的性价值得以实现。 相似文献

This paper reports an experiment designed to assess the effects of a rotation in the marginal cost curve on convergence in a repeated Cournot triopoly. Increasing the cost curve's slope both reduces the serially-undominated set to the Nash prediction, and increases the peakedness of earnings. We observe higher rates of Nash equilibrium play in the design with the steeper marginal cost schedule, but only when participants are also rematched after each decision. Examination of response patterns suggests that the treatment with a steeper marginal cost curve and with a re-matching of participants across periods induces the selection of Nash Consistent responses. 相似文献

This paper provides a model of democratic government as a compound of independent elective and non elective centers of power that compete in fostering the demands of voters and of interest groups. The analysis describes how interests of voters and of pressure groups are represented and under what conditions the compound democracy is more responsive to voters' or to interest groups' demands. These conditions are shown to depend on the center of power's relative opportunity costs at serving a plurality of interests and on the severeness of informational asymmetries between voters and interest groups. 相似文献

Levels of insurance against unemployment vary considerably across countries. Replacement rates, the ratio relating income from unemployment to what people earned when they were employed, are higher in countries with proportional electoral systems than in countries with majoritarian systems. Also, replacement rates are positively correlated with per capita income and negatively correlated with the countries' unemployment rates. I develop an electoral competition model that replicates these stylized facts. 相似文献

Taxation of Mobile Factors as Insurance under Uncertainty 总被引:1,自引:0,他引:1
Kangoh Lee 《The Scandinavian journal of economics》2004,106(2):253-271
This paper considers the effects of the taxation of mobile factors, i.e., capital, under uncertainty. The wages earned by residents of a jurisdiction are uncertain due to random shocks. Since the uncertain wages in a jurisdiction depend on the amount of mobile capital employed in the jurisdiction, and since taxation alters the quantity of capital employed, taxation affects the riskiness of uncertain wages. In particular, the taxation of capital moderates the fluctuation of uncertain wages, thereby providing insurance. For this reason, jurisdictions use distortionary capital taxation even if lump‐sum taxation is available. In addition, this insurance effect counteracts the tendency toward too low tax rates on capital arising from tax competition, and possibly improves the efficiency of tax competition. 相似文献

本文结合中国银行业竞争日趋激烈的现实背景,从商业银行专用性人力资本投资激励的独特视角入手,分别讨论了银行高层管理者和普通员工的专用性人力资本投资激励与他们参与银行公司治理机制的有关问题.研究发现,在国有商业银行公司治理结构改善过程中,更需要增加专用性人力资本投资的有效激励,并通过积极引入境外战略投资者和加强职工代表在银行监事会中影响力的办法,进一步激励银行员工进行能够提高银行经营绩效的专用性人力资本投资. 相似文献

Abstract. This paper analyses taxation in the presence of distortions in goods and labour markets in an endogenous growth model. The government disposes of capital, labour and consumption taxes. It is shown that the market solution leads to suboptimally low levels of growth and employment. However, available tax instruments are sufficient to attain the first‐best growth path in this economy. The paper further explores the relative distortion of capital and labour taxes. For plausible parametrisations of the model, lowering capital taxes dominate reductions in labour taxes in welfare terms. 相似文献

Use of biofuels diminishes fossil fuelcombustion thereby also reducing net greenhousegas emissions. However, subsidies are
neededto make agricultural biofuel productioneconomically feasible. To explore the economicpotential of biofuels in a greenhouse
gasmitigation market, we incorporate data onproduction and biofuel processing for thedesignated energy crops switchgrass,
hybridpoplar, and willow in an U.S. AgriculturalSector Model along with data on traditionalcrop-livestock production and processing,
andafforestation of cropland. Net emissioncoefficients on all included agriculturalpractices are estimated through crop growthsimulation
models or taken from the literature. Potential emission mitigation policies ormarkets are simulated via hypothetical carbonprices.
At each carbon price level, theAgricultural Sector Model computes the newmarket equilibrium, revealing agriculturalcommodity
prices, regionally specificproduction, input use, and welfare levels,environmental impacts, and adoption ofalternative management
practices such asbiofuel production. Results indicate no rolefor biofuels below carbon prices of $40 perton of carbon equivalent.
At these incentivelevels, emission reductions via reduced soiltillage and afforestation are more costefficient. For carbon
prices above $70,biofuels dominate all other agriculturalmitigation strategies. 相似文献
