This paper investigates the link between a firm's process innovation (PI) and its segment productivity at different life cycles. The results show that business diversification is negatively associated with a firm's productivity, and further reveal that a firm's PI moderates the above relationship. In addition, the corporate life cycle literature builds blocks for this study to explain that the involvement of administrative costs varies across life cycles when diversified firms get mature and bigger. Our empirical evidence indicates that the potential costs of a complex organisational structure contingent on business diversification at a firm's mature life cycle could be alleviated by the conduct of process innovation. As process innovation at different life cycles may alter managerial incentive that leads to different firm performance, the managerial implication is that diversified firms should appropriately engage in process innovation to prevent unfavourable liability from the development of their businesses. 相似文献

The Prebisch–Singer hypothesis in economics asserts that over time the relative price of primary goods relative to manufactured goods should experience a downward trend. To test the hypothesis, we must first establish the unit root properties of the relative price term and then regress the stationary series on a trend term. We use the quantile unit root test which allows for both smooth unknown numbers and the form of breaks in the trend function through a Fourier function to show that the relative price of 23 out of 24 primary goods is stationary. However, the Prebisch–Singer hypothesis is supported only in half of the primary commodities. 相似文献

本文基于1997—2010年267个地级及以上城市市辖区面板数据,运用标准化供给面系统方法测算了市级层面的技术进步方向,并借助“撤县设区”这一自然实验,利用工具变量法实证检验了要素结构变动对技术进步方向的影响,研究发现:(1)“撤县设区”使得资本—劳动比上升,进而导致技术进步方向偏向于资本,符合偏向型技术进步的“弱诱导偏向型假说”;(2)“撤县设区”对资本偏向型技术进步的影响是有条件的,主要限于资本—劳动替代弹性大于1即资本—劳动呈替代关系的地区;(3)相比于中西部地区,东部地区资本要素更为丰富,因而“撤县设区”显著提高了东部地区的资本—劳动比,使其技术进步方向偏向资本。 相似文献

ABSTRACT This study examines the four commonly tested hypotheses in hydroelectricity consumption – economic growth literature for 12 Asian countries. Our results from a recently developed hidden cointegration technique uncover rich and significant relationships between negative and positive components of the variables under consideration. In particular, we find evidence to support the neutrality hypothesis in five countries (Bangladesh, Indonesia, Pakistan, Philippines, and Thailand), the growth hypothesis in four countries (India, Japan, South Korea and Taiwan), and both growth and conservation hypotheses in three countries (China, Malaysia, and New Zealand). These findings suggest that appropriate economic policies should be elaborated on the basis of the country’s specific hydroelectricity consumption–growth nexus. Finally, our new evidence suggests that the lack of stable relationship between hydroelectricity consumption and economic growth documented in previous studies for some of these countries could be due to the failure to properly account for the nonlinearity property in the data. 相似文献

Summary. It is commonly argued that poorly designed banking system safety nets are largely to blame for the frequency and severity of modern banking crises. For example, underpriced deposit insurance and/or low reserve requirements are often viewed as factors that encourage risk-taking by banks. In this paper, we study the effects of three policy variables: deposit insurance premia, reserve requirements and the way in which the costs of bank bailouts are financed. We show that when deposit insurance premia are low, the monetization of bank bailout costs may not be more inflationary than financing these costs out of general revenue. This is because, while monetizing the costs increases the inflation tax rate, higher levels of general taxation reduce savings, deposits, bank reserves, and the inflation tax base. Increasing the inflation tax rate obviously raises inflation, but so does an erosion of the inflation tax base. We also find that low deposit insurance premia or low reserve requirements may not be associated with a high rate of bank failure.Received: 2 January 2002, Revised: 1 March 2003JEL Classification Numbers:

Since the passage of the Science and Technology Basic Law in 1999, Taiwanese universities have taken a more “scientific-economic” approach to protect and commercialize their research. This research mainly examines innovation activities such as patenting, licensing, and incubated startups in the context of Taiwanese higher education institutions (HEIs). The “scientific-economic” framework used to analyze the strategic aspects influencing these academic innovations includes (1) intellectual property managerial capabilities, (2) the strength of external industrial partnerships, (3) the university entrepreneurial orientation, and (4) government research policy. Four hypotheses were developed. Data were collected via a questionnaire with all 122 HEIs in Taiwan surveyed.The research reveals that the aspects of intellectual property managerial capability, HEI-industry partnerships, and academic entrepreneurial orientation are useful to distinguish the university's innovation performance on patent grants, licensing incomes, and firm incubation. Also, government support on research plays a moderating role in academic innovation. Managerial and policy implications for managing innovation effectively in universities were drawn. 相似文献

This paper studies minimally-supported D-optimal designs for polynomial regression model with logarithmically concave (log-concave) weight functions. Many commonly
used weight functions in the design literature are log-concave. For example,
and exp(−x
2) in Theorem 2.3.2 of Fedorov (Theory of optimal experiments, 1972) are all log-concave. We show that the determinant of information
matrix of minimally-supported design is a log-concave function of ordered support points and the D-optimal design is unique. Therefore, the numerically D-optimal designs can be constructed efficiently by cyclic exchange algorithm. 相似文献

This paper sets up a simple endogenous growth model that highlights the importance of the endogenous labor-leisure choice and the allocation between production labor and abatement labor. We show that, in contrast to the common notion (e.g. [Bovenberg, A.L., Smulders, S., 1996. Transitional impacts of environmental policy in an endogenous growth model. International Economic Review 37, 861–893] and [Bovenberg, A.L., de Mooij, R.A., 1997. Environmental tax reform and endogenous growth. Journal of Public Economics 63, 207–237]), the existence of an environmental production externality is a sufficient (but not necessary) condition for environmental policies to stimulate economic growth if the labor-leisure choice is endogenously determined. In particular, since there are complementarities between public abatement and private abatement, the public abatement expenditure will have a more powerful enhancing effect on economic growth when it is accompanied by more efficient private abatement. This result also leads to a corollary to the effect that it is easier to achieve double dividends in terms of enhancing both growth and welfare if the endogenous labor-leisure choice is taken into account.In our dynamic analysis, we show that if public abatement is substantially large, dynamic indeterminacy may occur despite the absence of a positive labor externality and interestingly, this is more likely to be the case when abatement labor plays a more significant role. Besides, the transitional effects of an increase in public abatement are also investigated. 相似文献

中国银行业监管机构中国银监会始于2006年逐步放松对城商行属地原则的限制,城商行“走出去”发展也渐趋成势。本文将重力去管制模型(Gravity deregulation Model)和放松管制政策相结合,一定程度上克服了内生性问题。研究结果表明,由于属地原则放松,城商行呈现出地理多元化的发展趋势,而城商行分支机构地理多元化对银行绩效具有一定的抑制作用。实证研究发现:总部与分支机构之间的距离不断扩大,银行资产收益率和资产回报率进一步降低;但是,其相对市场规模越大,资产收益率和净资产收益率会有一定程度的提升。这种抑制作用反映了总部与异地分支机构间存在信息不对称和代理问题。 相似文献
