Democracy and Growth: Alternative Approaches   总被引:2,自引:0,他引:2  
This article focuses on two previously unexamined aspects of the relationship between economic growth and democracy. First, the growth experiences of countries that experience significant changes in democracy are examined directly. Countries that democratize are found to grow faster than a priori similar countries, while countries that become less democratic grow more slowly than comparable countries. These differences do not seem to be due to differences in education or investment levels. Second, regression tree analysis suggests that democracy, along with initial income and literacy, contributes to the identification of regimes of countries facing similar aggregate production functions.  相似文献

At the dawn of the 21st century, global competition continues to increase at an accelerating rate and radical innovation is recognized as a potent weapon for firms to achieve sustainable competitive advantages. Academics, practitioners and consultants share the view that radical innovation is important to the long-term financial success of firms. Nevertheless, empirical studies on the relationship between radical innovation and firm performance have been dominated by survey research, which provided little concrete evidence on the financial impact of radical innovation. In this study we traced the financial performance of publicly traded manufacturing firms in the United States that introduced radical innovations over the period 1986-2000 and examined whether radical innovation could lead to superior financial performance in these firms. We employed the event-study method, matching each sample firm with a control group of firms in the same industry with similar pre-event performance and firm size. Our results show that while radical innovation helps firms maintain sales growth and return on sales (ROS), firm profitability in terms of return on assets (ROA) is not significantly improved. In fact, manufacturers suffer from a decline in profitability upon the introduction of radical innovations in new product development.  相似文献

Despite extensive research on corporate responsibility, little research exists on how the inter‐organizational processes of defining corporate responsibility develop. In this paper, we present a framework based on actor‐network theory (ANT) for analysing these processes. The developed framework is illustrated in a study of the redefinition of Swedish garment retailers' responsibilities for workers' rights at suppliers' factories between 1996 and 2004. We show that definition processes can be characterized as battles for the right to interpretation, and that traditionally non‐dominant actors can, at least temporarily, win these battles and dictate the development of the processes for defining corporate responsibility. We also show that definition processes can take an exclusionary form prohibiting certain actors from participating. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.  相似文献

We investigate whether dividends convey information about the risk of a company by examining the reaction of implied volatility in the option market to the announcement of a dividend initiation. Implied volatility decreases after the announcement and the magnitude of the decline in volatility is positively related to both the magnitude of cumulative abnormal returns (CAR) in the equity markets and the size of the dividend. Additionally, firms with weaker (stronger) corporate governance experience larger (smaller) declines in implied volatility. Cross sectional analysis shows that a one-standard deviation decline in measures of risk increases the 2-day CAR by 74–137 basis points. Our results suggest that dividend initiations signal declining firm risk.  相似文献

A frequent assertion of economists and political scientists is that democracy is a normal good, or that higher incomes lead citizens to “desire” more democracy. This assertion, however, has been difficult to test directly. I introduce a data set of democratic movements, and use it to address the relationship between income and the demand for democracy. Logit analysis of the estimated probability that a democratic movement occurs in an authoritarian country suggests that this probability is increasing in income per capita up to a level of approximately $5000. Unlike previous results, this does not suggest that all countries will become democratic once they pass some income threshold.  相似文献

Cannabis, Alcohol and Cigarettes: Substitutes or Complements?   总被引:1,自引:0,他引:1  
This paper uses individual level data from the National Drug Strategy Household Surveys to estimate the price responsiveness of participation in cannabis, alcohol and cigarette use. In addition to own price effects, we estimate cross price effects and the impact of decriminalizing cannabis use. We find that participation is responsive to own prices. There is some evidence that cannabis is a substitute for alcohol and a complement to cigarettes, and that alcohol and cigarettes are complements. The liberalization of cannabis laws in South Australia may have led to a temporary increase in cannabis use among the over-30 age group.  相似文献

This paper focuses on recent British experience with telematics-based Demand Responsive Transport (DRT) services in rural areas. In recent years, the ability of DRT concepts to provide efficient, viable transport services has been greatly enhanced by the use of transport telematics as demonstrated in a variety of environments across Europe. The success of British local authorities in winning substantial funding under the Rural and Urban Bus Challenge programmes for the implementation of DRT has resulted in widespread interest in flexible forms of transport. It is thus timely to evaluate the impact of this substantial investment. Drawing on the experience of a number of UK schemes, the paper assesses the reasons for the new-found success of what is becoming a relatively well-accepted mode by concentrating on a variety of factors including: service characteristics (particularly route flexibility, flexibility of booking method and pre-booking regime), emerging markets and the overall contribution of DRT to increased social inclusion and intermodality. Impediments to the development of DRT services are highlighted. The paper also discusses current research into the next generation of DRT services and concludes by identifying some key issues for policy-makers concerned with the future implementation of DRT services.  相似文献

Over the last decade Demand Responsive Transport (DRT) services have grown in popularity for several reasons including: the shortcomings of conventional regular bus and taxi services; shortcomings of special transport services; and new developments in community transport. Traditional dial-a-ride services have often been criticised because of their relatively high cost of provision, their lack of flexibility in route planning and their inability to manage high demand. The potential for overcoming these limitations may be realised through the introduction of telematics-based DRT and this has been widely demonstrated, for example, in recent research funded by the European Commission (e.g. the DGXIII-funded SAMPO and SAMPLUS projects). This paper provides an introduction to the concept of telematics-based DRT services and presents the results of the evaluation of a set of DRT technologies and operations at urban and rural sites across Europe. The paper offers discussion in terms of the key issues that influence the introduction of DRT services.  相似文献
