The paper offers an analysis of empirical evidence on the equity impacts of operational Bus Rapid Transit (BRT) systems in the Global South. The focus is on vertical equity, i.e. whether BRT systems achieve progressive benefits for poorer segments of the population. Findings from Africa, Asia, and Latin America all suggest that BRT does offer significant benefits to low-income groups, in terms of travel time and cost savings, access enhancement, and safety and health benefits. However benefits are often skewed toward medium-income users and thus less progressive than they might be. Two primary reasons for this are insufficient spatial coverage and inappropriate fare policies. While many features of BRT potentially allow it to deliver pro-poor outcomes, such outcomes only materialize if BRT implementers pay specific and sustained attention to equity. The paper identifies key issues that need to be addressed to steer BRT implementation toward more socially sustainable outcomes—including better integration with other transit, paratransit, and nonmotorized transport services, and with the housing sector.  相似文献

The discussion centers on three key criticisms of life history techniques, which are reviewed and evaluated with reference to data from research on Pakistani housing histories in Glasgow. Firstly, the problem of bias is reframed as an issue of reflexivity, which enhances research findings. Secondly, awareness of the cultural construction of life histories allows greater depth of analysis. And thirdly the problem of the relationship between the life history and wider social forces is argued to increase awareness and understanding of social actor agency. In conclusion, we argue that life history techniques can develop research on housing careers, particularly of Pakistanis, provided certain of their properties are recognised in the process of analysis.  相似文献

This study attempts to reassess the evidence on the degree of capital mobility and crowding out by applying a varying coefficients model to data on 19 OECD countries over the 1971–1999 period. Our period-specific results strongly support the crowding-out effect as well as the low capital mobility argument for this group of countries as a whole. However, the strength of the crowding-out effect appears to weaken and the degree of capital mobility to increase in the 1990s as compared to the 1970s and 1980s. We also classify countries into five groups according to the relative size of the government sector. Our group-specific results indicate that the degree of capital mobility is generally lower and the crowding-out effect generally stronger, in country groups with smaller governments. The differences are especially evident when we compare the group with largest government size with all other groups, those differences between the latter being much more modest. However, significant differences in the country-specific results suggest that it is prudent to be cautious when we draw conclusions about crowding-out and capital mobility for specific countries from the period-wise or group-wise results. This is particularly important in drawing policy implications for specific countries.  相似文献

The frequent occurrence of crises in recent decades has triggered a debate between the proponents of Efficient market hypothesis and Fractal market hypothesis. While, the proponents of Efficient market hypothesis view crises as non-existent and highly improbable, the advocates of Fractal market hypothesis view crises as the dominance of certain investment horizons. We test whether the assertion of Fractal Market hypothesis regarding the dominance of certain frequencies during financial crises hold for the global stock markets. Following Kristoufek (Sci Rep 3:2857, 2013) the wavelet power spectra based on continuous wavelet framework are used to test the said hypothesis. It is shown that stock markets around the globe indicate the dominance of higher frequencies during the crises periods, hence, validate the assertions of Fractal market hypothesis. The results drawn are robust to the use of different countries as well as different crises.  相似文献

Those responsible for making decisions in hospitals are increasingly aware of the need to efficiently manage hospital systems. An option for analysis is done by queuing models. In this paper is analyzed the service area ER, in a public hospital applying the concepts and relationships of waiting lines. From the model results, it is concluded that in the emergency department does not have the required minimum number of doctors to allow a steady flow of patients. With the model, the minimum required number of doctors is calculated to meet current and future demand for service with the same service time and the same discipline of service. Analytical models, allowing direct understand the relationships between service demand, number of doctors and patient care priority viewed as a queuing system. The work is useful for administrators and managers of hospital systems.  相似文献

Many option pricing models are based on the assumption that the underlying asset price follows one-dimensional diffusion process. An alternative approach is to test the properties that should hold for all models based on a given stochastic process for the underlying asset. Following Pérignon (2006 Pérignon, C. 2006. Testing the monotonicity property of option prices. Journal of Derivatives, 14: 6176. [Crossref] [Google Scholar]), we test the empirical validity of the monotonicity property for option prices by collecting all transaction data from 1 July 2006 to 31 December 2006 for option contracts traded on the Taiwan Futures Exchange (TAIFEX). We find that sampled intraday option prices violate the monotonicity property between 29.97% and 57% of the time, and that call and put prices often increase, or decrease, together. We also find evidence to show that the frequent violations of the monotonicity property are to a large extent attributable to microstructure effects and that they arise from rational trading tactics.  相似文献

Are retraining programs for the unemployed more effective thanjob search assistance? Governments of the member countries ofthe Organisation for Economic Co-operation and Development haveconsiderable experience with retraining programs in a varietyof industrial settings. Evaluations of these programs show thatthe results are disappointing, however. This article discussesthe factors associated with retraining programs for two typesof workers: those laid off en masse and the long-term unemployed.Evaluations indicate poor results for both groups: retrainingprograms are generally no more effective than job search assistancein increasing either reemployment probabilities or postinterventionearnings, and they are between two and four times more expensivethan job search assistance.   相似文献

This paper extends the Feldstein-Horioka (1980), Feldstein (1983) and subsequent studies on the degree of capital mobility, by adopting a random coefficients model. This approach is more general in that it permits inter-country variations in the degree of capital mobility to arise due to the differences in size as well as in other institutional or structural characteristics. In addition, it is a refinement of stochastic laws as defined by Pratt and Schlaifer (1984, 1988). Our results point to significant inter-country differences in the degree of capital mobility, thereby lending support to the random coefficients approach. In particular, our results indicate that, on average, the degree of capital mobility is much higher than implied by fixed coefficients approach. Finally, country size itself does not appear to bear a systematic relationship with the degree of capital mobility as suggested by Murphy (1984).We are grateful to two anonymous referees, and Baldev Raj, Editor of the journal for helpful comments and suggestions. The usual caveat applies.  相似文献

ABSTRACT

The majority of researches on knowledge and technology transfer from universities focused on the topic of processes which can improve the efficiency of the commercialization of R&D results. Furthermore, the different channels of transfer have been studied mainly independent of each other. This article develops a more strategic approach and proposes an integrated view of 16 channels of transfer organized around four core competences and considering their main form of governance. The empirical analysis is based on data gathered through a survey and an interview on a sample of 29 Argentinian National Universities publicly funded. The findings highlight four types of strategies – integral, network, entrepreneurial and undetermined – and two main types of potential evolutionary paths. The ability to differentiate the scopes of the intervention of universities transfer activities has implications for universities as well as for policymakers.  相似文献

This study attempts to examine empirically the implications of the degree of openness for total and individual factor productivity growth in a group of 19 OECD countries over the last three decades. The study combines both time series and cross-sectional data. The model employed is a generalization of the commonly used, growth-accounting model based on the concept of an aggregate production function in which the rate of economic growth is a function of capital and labour accumulation and total factor productivity. It is explicitly assumed that total factor productivity depends, in turn, upon the rate of export expansion. The model is then estimated using the random coefficients approach. While results generally indicate that the relative importance of trade openness on economic growth varies significantly across countries, they also indicate that the role of capital and labour accumulation in fostering economic growth varies with the degree of openness, cross-sectionally as well as across time.  相似文献
