This paper examines the possibility of unit roots in the presence of endogenously determined multiple structural breaks in the total, female and male labour force participation rates (LFPR) for Australia, Canada and the USA. We extend the procedure of Gil‐Alana for a single structural break to the case of multiple structural breaks at endogenously determined dates using the principles suggested by Bai and Perron. We use the Robinson LM test to determine the fractional order of integration. We find that endogenously determined structural breaks render the total, female and male LFPR series stationary or at best mean‐reverting. 相似文献

This paper investigates the channels through which the middle class may matter for consumption growth. Using several different middle‐class measures and a panel of 105 developing countries spanning the period 1985–2013, we find that a larger middle class influences consumption growth primarily through higher levels of human capital accumulation. There is also a significant direct effect of middle‐class size on consumption growth, which is more pronounced in the latter half of the sample, the 2000–2013 period. 相似文献

The financing channel of a fiscal stimulus matters for the size and the sign of the fiscal multiplier. We develop a general equilibrium model where a fiscal stimulus is partially bank-funded and the government becomes the dominant borrower from banks relative to entrepreneurs. This leads to a negative impact on credit spreads, investment and a contraction in output. We support our story with a structural vector autoregression for a sample of developing countries featuring the dominant borrower syndrome. 相似文献

This study investigates the effects of early smoking on educational attainment and labor market performance by using mixed ordered and mixed proportional hazard models. The results show that early smoking adversely affects educational attainment and initial labor market performance, but only for males. The probability to finish a scientific degree is 4%-point lower for an early smoker. The effect of early smoking on initial labor market performance is indirect through educational attainment. Once the indirect effect is controlled for there is no direct effect. Moreover, for males only, early smoking has a negative effect on current labor market performance even after conditioning on educational attainment. The probability to have an academic job is 4%-point lower for an early smoker. For females neither education nor labor market performance is affected by early smoking. 相似文献

Within the context of a small open economy model, this paper examines the repercussions of induced currency depreciation. The results presented in this paper are based on a model with firm microeconomic foundations and which takes into account both the supply and demand-side effects of exchange rate variations. The distinguishing feature of the model is the role of exchange rate expectations. We consider three kinds of expectations; adaptive, extrapolative, and regressive expectations. We also perform several sensitivity tests based on these expectations. Our simulation exercise shows that the effect of induced currency depreciation depends largely on supply-side effects. In most cases, we find that currency depreciation results in (i) a fall in output, (ii) an increase in prices and (iii) an improvement in the balance of trade. In the absence of weak supply-side effects of exchange rates, we find that, if the Marshall-Lerner conditions hold, then depreciation of the home currency has a favorable effect on output but its effect on the balance of trade is negative. 相似文献

Mining activities and tourism are both growing fast in biodiversity intense areas globally. However, the dynamic and interactions between mining and tourism when they both occur in biodiversity hotspots, and how they together may impact the economy and environment in these biodiversity rich areas, remain unclear. This paper examined how the two industries interact in terms of their economic contributions and spatial patterns in a biodiversity hotspot, Yunnan, China. We used correlation analyses to measure the relationships between mining activities, tourism visits and local gross domestic productions. We also employed a distance-based technique to investigate the nature of any dependency between mining and tourism sites. Results showed that mining activities tend to be in relatively fluent areas while tourism tends to occur in less developed areas. Our results showed that the location of tourism and mining sites are likely to be close to one another but the two industries usually perform better economically when they are apart from each other. These findings can provide insights on how mining and tourism together may impact the economy and environment in biodiversity rich areas, and provide important information for managers and planners on balancing mining and tourism development in these areas. 相似文献

INTER-REGIONAL FARM EFFICIENCY IN PAKISTAN'S PUNJAB: A FRONTIER PRODUCTION FUNCTION STUDY 总被引:1,自引:0,他引:1
Agricultural production efficiency in four irrigated cropping regions of the Punjab province of Pakistan was compared on the basis of a probabilistic frontier production function estimated from whole-farm survey data for the year 1984-85. It is found that the gross income of farmers can be increased by 13% at the current levels of resource use if the production gap between ‘best practice’ and ‘average’ farmers is suitably narrowed in all cropping regions. This will increase profits by up to 40%. No significant difference in technical efficiency was found across the regions. Economic efficiency was similar across all cropping regions except in the cotton region, which had significantly lower economic efficiency due to higher allocative inefficiency, which in turn was attributable to the more dynamic production technologies being adopted in that region. 相似文献

Nearly-Singular design relaxes the nonsingularity assumption of the limit weight matrix in GMM, and the nonsingularity of the limit variance matrix for the first order conditions in GEL. The sample versions of these matrices are nonsingular, but in large samples we assume these sample matrices converge to a singular matrix. This can result in size distortions for the overidentifying restrictions test and large bias for the estimators. This nearly-singular design may occur because of the similar instruments in these matrices. We derive the large sample theory for GMM and GEL estimators under nearly-singular design. The rate of convergence of the estimators is slower than root n. 相似文献

This study surveyed 497 participants to determine the factors that affect project professionals' acceptance of project management software and the perceived impact of software usage on their performance. The study finds that greater information quality and higher project complexity are the dominant factors explaining higher levels of system utilization, that greater system functionality and ease of use have a significant positive relationship with increased software usage, and that a strong positive relationship exists between higher usage of project management software and perceived project managers' improved performance. Inconsistent with prior research, more training was not found to be associated with project management software usage. The study explains more than 40% of the variation in project management software acceptance and adds project management software usage to project success factors by empirically confirming for the first time that project management software enhances project professionals' perceived performance and provides a positive impact on the results of their projects. The study provides practical implications for project professionals, their organizations, senior management, decision makers, software developers, and vendors. These findings support the call for further research that investigates the diffusion of information technologies in the project management field and their impact on project success and competitive position. 相似文献
