A number affirms use external sourcing of technology to create technological change in their organizations. In this article, Falguni Sen and Albert Rubenstein develop a rationale to support the concept of an integrative technology development strategy which emphasizes the role of in-house R&D during the planning and implementation process for externally sourced technology. They divide the external sourcing process into two major components: an acquisition phase and an implementation phase. Next, they define five distinct stages within both phases. Based on a review of the literature, the authors identify some common problems with external sourcing and discuss potential ways that in-house R&D can alleviate them by becoming involved in specific steps in each of the ten stages. The data in the article have been obtained from thirty-one cases of external sourcing of technology from a diverse group of industries in the United States and India. R&D's involvement in the external technology process varies among firms and is generally low in the acquisition phase. In the research, R&D managers describe barriers to their involvement, and the article develops measures of effectiveness of the activities in each stage of the external sourcing process. The authors recommend removing relevant barriers, especially in those stages where the involvement of in-house R&D groups could increase the effectiveness of the process. 相似文献

Dualism is a pervasive feature of the manufacturing sectors of less-developed countries, with large differences in productivity between the informal and the formal sectors. Policy distortions are viewed as an important factor behind the prevalence of manufacturing dualism. We examine whether tariff reforms, industrial de-licensing and the withdrawal of reservation of products for small firms implemented since the mid-1980s have had any effects on efficiency differentials between informal and formal firms in Indian manufacturing. We find strong evidence that economic reforms have exacerbated dualism by increasing the productivity differentials between the more efficient formal firms and the less efficient informal firms. 相似文献

It is generally accepted that the Australian economy is continually subject to unanticipated shocks, particularly, unexpected swings in the prices of Australia's internationally- traded goods. This article empirically investigates the nature and extent of volatility in import and export prices faced by the Australian production sector. It estimates multivariate GARCH models of the stochastic processes generating the prices of imports and exports, and of important components of exports and imports. This article proposes an index of volatility, which is used to provide a summary measure of the extent of volatility in a multivariate context. The overall conclusion is that the price growth rates for Australia's traded goods exhibit considerable time variation in volatility and that these price growth rates are highly and positively correlated with each other. 相似文献

This article tests for the presence of a unit-root in all time series included in the extended Nelson–Plosser data set using the statistics devised by Zivot and Andrews, Perron and Murray and Zivot. It specifies the mixed model characterization of the trend-break stationary alternative that allows for a simultaneous break in both the intercept and slope of the trend-function. It rejects the unit-root null hypothesis for real GNP, nominal GNP, real per capita GNP, industrial production, employment, GNP deflator, nominal wages, interest rate and common stock prices. Use of appropriate critical values to assess the significance of the trend-function coefficients reveals that the slope-break should be included in real GNP, nominal GNP, real per capita GNP, nominal wages, interest rate and common stock prices. The results indicate that there is less evidence against the unit-root hypothesis with the extended Nelson–Plosser data compared to the original Nelson–Plosser data. 相似文献

境外公共治理的经验表明,在攸关民众切身利益政策的制定和实施过程中,服务对象的参与以及多方合作制衡有助于更好地维护公众利益。国内公共服务的管理一直强调政府与服务提供机构之间的博弈,而忽视了公众方的参与。近年来一些部门和地区开始探索建立公共服务机构的治理机制。我们建议,在完善公众知情权和评议权基础上,中央政府应该着力推进公共服务法人治理结构的试点。近期可由政府主导政策过程,其他利益相关者参与监督和咨询;远期应赋予社会公众代表平等参与决策等核心职权。 相似文献

This paper presents a method for fitting a copula‐driven generalized linear mixed models. For added flexibility, the skew‐normal copula is adopted for fitting. The correlation matrix of the skew‐normal copula is used to capture the dependence structure within units, while the fixed and random effects coefficients are estimated through the mean of the copula. For estimation, a Monte Carlo expectation–maximization algorithm is developed. Simulations are shown alongside a real data example from the Framingham Heart Study. 相似文献

In the aftermath of the recent global financial crisis, monetary authorities, while pursuing traditional objectives, such as the control of inflation, are also eager to promote financial stability. In this paper, we model the strategic interaction of the central bank and the financial sector and explore a simple monetary policy game with perceived substantial risks to financial stability, where the central bank can be of two types, one pursuing strict inflation-targeting and the other concerned with affecting the expectations formed by the financial sector participants; however, the financial sector is unsure which, due to incomplete information. The conclusion is that for small shocks to inflation there is a pooling equilibrium, whereas for larger shocks there is separation. In the latter case, the central bank that has an explicit financial stability concern is willing to exercise more muted control to inflation in order to reinforce the safety of the financial sector. 相似文献
