Mijatovi? and Pistorius proposed an efficient Markov chain approximation method for pricing European and barrier options in general one‐dimensional Markovian models. However, sharp convergence rates of this method for realistic financial payoffs, which are nonsmooth, are rarely available. In this paper, we solve this problem for general one‐dimensional diffusion models, which play a fundamental role in financial applications. For such models, the Markov chain approximation method is equivalent to the method of lines using the central difference. Our analysis is based on the spectral representation of the exact solution and the approximate solution. By establishing the convergence rate for the eigenvalues and the eigenfunctions, we obtain sharp convergence rates for the transition density and the price of options with nonsmooth payoffs. In particular, we show that for call‐/put‐type payoffs, convergence is second order, while for digital‐type payoffs, convergence is generally only first order. Furthermore, we provide theoretical justification for two well‐known smoothing techniques that can restore second‐order convergence for digital‐type payoffs and explain oscillations observed in the convergence for options with nonsmooth payoffs. As an extension, we also establish sharp convergence rates for European options for a rich class of Markovian jump models constructed from diffusions via subordination. The theoretical estimates are confirmed using numerical examples.  相似文献

This study examines how relationship innovation can be developed in global collaborative partnerships (alliances, joint ventures, mergers, and acquisitions). The recently emerging theory of big data analytics linked with traditional organizational powers has attracted a growing interest, but surprisingly little research has been devoted to this important and complex topic. Therefore, after developing the theoretical foundations, our study empirically quantifies the links between the theoretical constructs based on the data collected from chief executive officers, managing directors, and heads of departments who work in contemporary global data‐and‐information driven collaborative partnerships. The results from structural equation modeling indicate that the relationship innovation depends on the power of big data analytics and non‐mediated powers (NMP, expert and referent). The power of big data analytics also mediates the correlation between NMP and relationship innovation. However, mediated powers (coercive and manipulative) negatively affect the power of big data analytics and relationship innovation. The interaction effects further depict that analytically powered partnerships have better relationship innovation compared with those which focus less on the analytical power. Consequently, the contributions of this study provide a deeper understanding of mechanisms of how modern collaborative partnerships can use big data analytics and traditional organizational powers to co‐create relationship innovation.  相似文献

In the context of personal income tax (PIT) reform in China in 2018, this paper examines some of the major issues of concern regarding the reform and income distribution. Using the China Personal Income Tax Micro‐simulation model, the paper compares the differences between the 2011 and 2018 PIT systems, and finds that residents relying on different income sources may face a large degree of real tax rate change. Once the tax system is altered to PIT 2018, the coverage of PIT for wage earners will decrease from 46.9 to 23.4 percent, the income redistributive effect will drop from 1.95 to 1.22 percent and the PIT's role in fiscal revenue will also be negatively affected. Nevertheless, if individual income continues to grow, the share of PIT in fiscal revenue is expected to return to the 2018 level in 2022, but its income redistribution function is difficult to recover in the short term. The paper finds that the effect of PIT on income distribution depends on the tax structure. Gradual transition to an “entirely comprehensive” tax system when conditions are appropriate will achieve better income redistribution results at a lower average tax rate.  相似文献

Current turnover research fails to serve the needs of an industry that is long plagued by employee turnover. Existing literature focuses more on evaluating bundles of human resource practices and fail to provide precise and clear guidance for practitioners. This study proposes that emotional intelligence (EI) unifies sufficient individual factors and organizational factors that affect employee turnover and serves as a single significant precedent for turnover. Data were collected from frontline employees at eight luxury hotels. The direct, indirect, and total impacts of employee EI on employee turnover were tested by structural equation modeling and bootstrap tests. The results suggest that EI has significant indirect impacts through the mediation of perceived organizational support, pay satisfaction and job burnout, and significant total impacts on turnover. Implication suggestions include integrating EI into the recruiting process for new employees and providing training opportunities for current employees to improve their EI.  相似文献

China's political and economic systems are often discussed in combination. It is generally believed that under the political system of centralization, the economic system had to be a state monopoly. This article challenges that view by providing an economic perspective. The period 1949–1984 is selected to explore the causes of successive periods of strengthening and weakening of the state's monopoly power over the economy. Scholars have generally assumed that the period of state monopoly originated from socialist ideology or the personal will of the leaders. But economic conditions severely limited the options available. After the new China was established, the Chinese Communist Party (CCP) did not try to create a fully socialist economy in the short run. Instead, the CCP formulated a New Democracy platform that pragmatically allowed many types of enterprise to function side by side, including private industry, household ventures, and state‐owned enterprises. The original plan of the CCP was to allow private enterprise to develop in order to build up capital to rebuild the war‐damaged economy so that a strong foundation could be established for creating a socialist economy. But the Korean War from 1950 to 1953 and an influx of Soviet capital caused a shift from a mixed economy to state capitalism by 1956. From that point on, Mao Zedong and other Chinese leaders had to change course again and again as fiscal crises limited available options. A reversal occurred in 1958 when the Soviets withdrew both their advisors and their capital subsidies, leaving the state capitalist system weakened. The crisis in the Chinese economy from 1959 to 1961 required decentralization of economic authority and efforts to promote rural capital formation. The next shift occurred after 1963 as the economy was organized to prepare for a possible military invasion. The required mobilization of industrial resources in remote regions of China inevitably reinforced state management of the economy. The final reversal occurred in the late 1970s, when imports of Western technology and equipment created another fiscal crisis for the central government, which then had to shift the burden of capital formation from the state to private entities. The reform of the rural household contract system, the adjustment of economic structures, and an increase in exports to gain foreign exchange all took place as part of “de‐monopolization” reforms. The reforms that occurred after 1979 were not an aberration or a radical break from the past. They were part of a pattern that evolved from 1949 to 1984, with fluctuations dependent on the weakening and strengthening status of state finances. The shifts that occurred during this period have either been ignored by observers, or they have been misinterpreted as being motivated by ideology. In fact, new policies were created to enable the government to adjust to changes in the internal and external environment.  相似文献

[目的]随着农村城镇化进程的加快,由此引发的农村居住地生态环境恶化已成为制约农业和农村经济可持续发展的瓶颈,加强农村居住地生态环境保护和治理,是目前亟待解决的重要问题。研究分析农村居住地生态环境影响因素,为有效改善居住地生态环境提供重要理论依据。[方法]以陕西省为主要研究区域,采用层次分析法,构建矩阵模型,研究影响陕西省农村居住地生态环境的农民因素、生产活动和政府因素3个层次,包括周边乡镇企业废物排放、农用投入品的使用、畜禽养殖业废物排放、人均消费支出、农村人均家庭纯收入、农村家庭恩格尔系数、环保意识、政府监管力度、环境保护财政支出,相关政策法规等10个因素所占权重,得到不同因素的重要性排序。[结果]乡镇企业废物排放、农用投入品的使用、农村人均家庭纯收入和农村人均消费支出是影响农村居住地生态环境的主要因素,且重要性排序为乡镇企业废物排放农用投入品的使用农村人均家庭纯收入农村人均消费支出。[结论]加强乡镇企业废物排放管理和农用投入品的生产和使用审查,降低不必要的消费支出,同时为农民提供更多的就业机会,提高人均家庭村收入,是目前改善农村居住地生态环境的有效措施,为农民提供一个安全舒适的居住场所,这也将有利于农村经济的可持续发展。  相似文献
