Using a simple two‐period model of investment, we show that there should be a nonlinear relation between a firm's investment‐to‐capital ratio and its subsequent stock returns. This prediction finds substantial empirical support. The evidence indicates that the slope of the investment function is negative at low investment levels, close to zero at intermediate investment levels and negative at high investment levels. Our results, which are robust to the use of narrowly‐ and broadly‐defined measures of capital investment, pose a challenge to the hypothesis that the negative cross‐sectional correlation between investment and stock returns is attributable to some sort of overinvestment phenomenon.  相似文献

The contribution of this paper consists in applying several techniques to estimate a composite indicator of sustainable urban mobility for 116 Italian provincial towns, as proposed by Luzzati and Gucciardi (2015). The aim is to provide the decision-maker with a richer set of information on sustainable mobility, making explicit the impact of the techniques used on the values obtained. A set of 16 indicators with a nested structure has been selected and 33 combinations of normalization, weighting, and aggregation techniques are applied. The results are presented by city, by city groupings (size and location), and focusing on the ten largest Italian cities. It is found that small cities perform better in terms of sustainable mobility than medium or large cities. As expected, in some cases (e.g., Milan) the intervals of the results obtained are quite large, indicating that the techniques used to normalize, weight, and aggregate the indicators highly affect the performance indexes. In other cases (e.g., Rome) the results are stable across methodologies.  相似文献

An integrated scenario analysis for the metal coating sector in Europe   总被引:1,自引:0,他引:1  
Although new paint products and technologies have been developed, the sector of paint application still contributes substantially to total volatile organic compound (VOC) emissions. Recent environmental legislation, especially the EU Solvent Emission Directive 1999/13/EC and its transposition into national law, coming into force in 2007, will have an important influence on the sector structure and the associated supply chain, especially for small- and medium-sized enterprises (SMEs). This paper summarises a comprehensive scenario analysis to explore possible future trajectories for the sector. The main focus is on paint application activities, considering in particular the consequences of new environmentally friendly products and technologies which can be used by SMEs. Four different scenarios representing possible future states of the sector are evaluated, taking into account environmental, technical and socio-economic aspects along the associated supply chain and life cycle. The scenarios allow the formulation of recommendations and guidelines for policy makers and industries. This example confirms that interdisciplinary scenario analysis is a suitable approach to investigate possible future development of an industrial sector.  相似文献

We study the asymptotic behavior of the optimal harvesting policies for a multiple species forest with a land market, i.e., any fraction of the land can be traded at any time stage. We prove the existence of sustainable states and we discuss the conditions under which any optimal trajectory converges in the long run towards one of these states or towards the set of optimal periodic cycles. We also discuss briefly a more general problem that includes costs of converting land between the different species.   相似文献

This study seeks to identify the causal effects of foreign ownership on productivity, the demand for skilled labour and wage inequality. With this aim, we use differences‐in‐differences techniques for a panel of Uruguayan manufacturing firms in the period 1997–2005. Our results seem to indicate that FDI causes higher productivity and increased demand for skilled labour. Furthermore, although average wages are higher in foreign‐owned firms than in domestic ones, the wage gap between skilled and unskilled workers is wider. It follows that promoting foreign investment enhances productivity. In addition, due to the greater demand for skilled workers, policies such as training schemes would be conducive to raising productivity still further, while other social policies could help to mitigate the wage inequality effects.  相似文献

This paper uses the Italian Social Security employer-employee panel to study the effects of the Italian reform of 1990 on worker and job flows. We exploit the fact that this reform increased unjust dismissal costs for businesses below 15 employees, while leaving dismissal costs unchanged for bigger businesses, to set up a natural experiment research design. We find that the increase in dismissal costs decreased accessions and separations for workers in small relative to large firms, especially in sectors with higher employment volatility, with a negligible impact on net employment. We also find some evidence suggesting that the reform reduced firms' entry rates and employment adjustments, but had no effect on exit rates.  相似文献

Reductions in firing costs are often advocated as a way of increasing the dynamism of labour markets in both developed and less developed countries. Evidence from Europe and the U.S. on the impact of firing costs has, however, been mixed. Moreover, legislative changes both in Europe and the U.S. have been limited. This paper, instead, examines the impact of the Colombian Labour Market Reform of 1990, which substantially reduced dismissal costs. I estimate the incidence of a reduction in firing costs on worker turnover by exploiting the temporal change in the Colombian labour legislation as well as the variability in coverage between formal and informal sector workers. Using a grouping estimator to control for common aggregate shocks and selection, I find that the exit hazard rates into and out of unemployment increased after the reform by over 1\% for formal workers (covered by the legislation) relative to informal workers (uncovered). The increase of the hazards implies a net decrease in unemployment of a third of a percentage point, which accounts for about one quarter of the fall in unemployment during the period of study.  相似文献

This paper adopts fixed‐effect panel methodologies to obtain TFP values for a sample of 76 countries from 1960 through 2003. Our results are robust to the use of different estimators (LSDV, Kiviet‐corrected LSDV, and GMM). They show that TFP dynamics are characterized by a process of conditional convergence where most countries do not catch up with the U.S., and where human capital plays an important role in technology adoption, as suggested by Nelson and Phelps in 1966. Such a role is robust to the inclusion of controls for the quality of institutions in a country. Further, our results imply a plausible link between stages of development and returns to different levels of education. Finally, we calculate the minimum human capital level necessary to generate catch‐up and find that virtually all countries are above that level—a result that again emphasizes the importance of human capital in technology diffusion.  相似文献

The now widely used term ‘Generation Rent’ reflects the growing phenomenon in the UK of young people living in the private rental sector for longer periods of their lives. Given the importance of leaving home in youth transitions to adulthood, this is a significant change. It is further critical given the rapid expansion of the private rented sector in the UK over recent decades and the more limited rights that private tenants have. This article draws on qualitative evidence to highlight the impact this has on young people's lives, and broader patterns of social‐spatial inequality. Our research highlights that, whilst young people retain long‐term preferences for homeownership, they nonetheless deconstruct this normalized ideal as a ‘fallacy of choice', given its unachievability in reality. Influenced by the work of Foucault, Bourdieu and Bauman, we emphasize how these dominant norms of housing consumption are in tension with objective reality, since young people's ability to become ‘responsible homeowners' is tempered by their material resources and the local housing opportunities available to them. Nonetheless, this does not exempt them from the ‘moral distinctions' being made, wherein renting is problematized and constructed as ‘flawed consumption'. These conceptual arguments advance international scholarly debates about the governance of consumption, offering a novel theoretical lens through which to examine the difficulties facing ‘Generation Rent’.  相似文献

In order to be successful in today's competitive environment, third‐party logistics providers (3PLs) increasingly strive to develop close, mutually beneficial long‐term relationships with customers. The current study identifies inter‐organizational conditions and firm‐specific factors that influence a firm's partnering behavior with its 3PL. A model of the antecedents and dimensions of partnering behavior is developed and tested with a diverse set of relationships between a focal 3PL and members of its customer base.  相似文献
