Over the last two decades several countries experienced currency crises. These were characterized both by a huge disruption of economic activity and an extreme speed of diffusion within countries. The financial turmoil happened in a period of very high degree of international financial integration. As a result financial liberalization was associated with greater incidence of crises and this brought an intense debate in both academic and policy circles about the consequences of free capital movements.  相似文献

As new media technologies develop and become established, the supply of media services expands. Along with this development, the question arises of how this affects traditional media. As other new media have, the Internet, too, has triggered debates about the future of the «old» media. This paper discusses whether the proliferation of the World Wide Web can have effects on television use. To do this, both relevant theoretical approaches and the state of empirical research are introduced and discussed. Present research results do not consider the systematic difference between cognitive schemata concerning media use as they are reproduced in face-to-face interviews on the one hand, and actual media use on the other. An innovative research concept is developed that takes this critique into account and differentiates between gratification expectations and situational gratifications sought and obtained. As regards gratification expectations, television is superior to the World Wide Web. It is more powerful on all gratification dimensions. Considering actual use, though, the World Wide Web has already outstripped television on some of the dimensions. It is used more often to satisfy specific needs. Thus, cognitive schemata of media use lag behind the actual changes in every day life.  相似文献

Taxation changes the expectations of prospective university students about their future level and uncertainty of after-tax income. To estimate the impact of taxes on university enrollment, we estimate a structural microeconometric model, in which a high-school graduate decides to enter university studies if expected lifetime utility from this choice is greater than that anticipated from starting to work right away. We estimate the ex-ante future paths of the expectation and variance of after-tax income for German high-school graduates, accounting for nonrandom selection. The enrollment model takes into account university dropout and unemployment risks. Consistently with expectations, the estimation results indicate that higher expected returns to a tertiary education increase the probability of university enrollment, whereas higher uncertainty among graduates decreases enrollment rates. A simulation based on the estimated model indicates that a revenue-neutral, flat-rate tax reform with an unchanged basic tax allowance would increase enrollment rates for men in Germany.  相似文献

In recent years, the emergence of electronic finance—especially online banking and brokerage services, and new trading systems—has reshaped the financial landscape around the world. This paper reviews these developments and finds that they are greatly impacting the structure of and competition in financial services industries and will have a large impact on incumbents. Its assessment of how e-finance, and globalization more generally, affects countries highlights the need for changes in four financial sector policy areas—safety and soundness, competition policy, consumer and investor protection, and global public policies—to mitigate risks and reap as much as possible the potential benefits of e-finance.  相似文献

The aim of this paper is to investigate the roots of the stagnation in the Italian total factor productivity (TFP). The analysis focuses on the specific pattern of technical progress in determining the dynamics of the TFP. This analysis cannot be done with Cobb-Douglas technology, but requires the employment of a constant elasticity of substitution (CES) production function that allows distinguishing between the direction and the bias of technical progress. We employ a CES specification embodying both labor- and capital-augmenting technical change, with a σ less than 1. We obtain three main results. (1) There seems to have been a structural break around the mid-1990s in the direction and bias of technological change; (2) The first half of the sample features a labor-augmenting technical change and a capital bias; and (3) In the second part of the sample, both these characteristics seem to disappear, and the evolution of factor endowments assumes a key role. This fact may be seen as one of the potential causes of the stagnation in Italian productivity.  相似文献

The aim of this article is to make a contribution to the reflection on the “interpretive turn” within Austrian economics going back to Alfred Schutz’s notion of life-world sketched out in his first book The Phenomenology of the Social World. In the context of the discussions on how hermeneutics can enrich economics, the problem of objectivism in the production of knowledge is emphasized, i.e., the danger of substitution of social reality upheld by social scientists. Although Schutz’s links with the Austrian School are well known, specialized literature, has not found in Schutz’s work comprehensive solution to the problem that objectivism sets forth regarding the production of knowledge in social sciences. In this article we aim to recover the radical character that Schutz granted his project on phenomenological foundation of social science concepts based on a thorough philosophical analysis of the features of the life-world. We will argue that Schutz sets off based on the problem objectivism in the production of knowledge and offers an answer geared towards the epistemic claim to the life-world. In this regard Schutz draws up a solution that brings together both at the life-world level and at the scientific reflection level, the subjective and objective, the aprioristic and the historical aspects of experience in a phenomenologically based continuum. Finally, and deeply connected to these considerations, new conceptual elements are brought forth to think of the problem of social order.  相似文献

Background: A recent randomized controlled trial showed that patients undergoing ascending aorta surgery treated with HEMOPATCH to control bleeding had a significantly better hemostasis success rate than with dry or wet gauze compression or similar standard of care (SOC).

Objective: To compare the cost-effectiveness using two different agents for hemostasis (HEMOPATCH vs dry or wet gauze compression or similar SOC) in cardiac surgery from the European hospital perspective.

Methods: A literature-based cost-effectiveness model estimating average cost per successful hemostasis event was developed based on the hemostasis efficacy difference (HEMOPATCH?=?97.6%, SOC?=?65.8%, p?<?.001). Additional clinically significant end-points studied in the trial (blood transfusions and surgical revisions) were also analyzed. It was assumed that each surgery utilized two units of HEMOPATCH (dimensions of 4.5?×?9?cm) and two units of SOC. Product acquisition costs for HEMOPATCH and SOC were included along with outcome-related costs derived from the literature and inflation-adjusted to 2017 EUR and GBP. Results are presented for an average hospital with an annual case load of 574 cardiac surgeries. One-way and probabilistic sensitivity analyses were performed.

Results: Considering only product acquisition cost, HEMOPATCH had an incremental cost-effectiveness ratio (ICER) of €1,659, €1,519, €1,623, and £1,725 per hemostasis success when compared to SOC for Italy, Spain, France, and the UK, respectively. However, when considering the cost and potential difference in the frequency of transfusions and revisions compared to SOC, the use of HEMOPATCH was associated with an annual reduction of six revisions and 60 transfusions, improving the ICER to €1,440, €1,222, €1,461, and £1,592, respectively. Sensitivity analysis demonstrated model robustness.

Conclusions: This analysis supports the use of HEMOPATCH over SOC in cardiac surgery in European hospitals to improve hemostasis success rates and potential cost offsets from reduced transfusions, complications, and surgical revisions.  相似文献

Since Provan and Milward’s article in 1995, a wide variety of conceptualizations and measures of network performance has been proposed. The lack of consensus among scholars generated a confusing landscape. In an attempt to wind a skein into a ball, our paper aims to synthesize the conceptualizations and measures of network performance proposed by the existing literature and explore their statistical and theoretical relationships. Structural equation modelling techniques were used for this purpose.  相似文献

Institutions play an important role in women’s and men’s entrepreneurial behaviors. This article provides a systematic review of institutions and women’s entrepreneurship literature through an institutional lens, with a particular focus on informal and formal institutions. The article sets out to explore institutions for women’s entrepreneurship, illustrating why having an institutional perspective of women’s entrepreneurship contributes to a deeper understanding of the phenomenon. To reach this aim, we analyze and classify the scholarship by explanatory factors and type of informal and formal institutions. The article suggests that gender roles, as an informal institution, influence the creation of both informal and formal institutions, and in turn, the women’s entrepreneurial behaviors is based on gender roles. Finally, a theoretical model is developed, which allocates women’s entrepreneurship in the center and shows the role of institutional environment in their decision to start new ventures. Implications for future research are finally discussed.  相似文献

Abstract

This study adds to the growing literature on the distributional effects of indirect or consumption taxes in developing countries by exploring whether these taxes have differential gender outcomes. Using data from Statistics South Africa's 2000 Income and Expenditure Survey, the study investigates differences in tax incidence between “female-type” and “male-type” households, classified according to their demographic and economic attributes. The results suggest that zero-rating a well-targeted selection of basic foodstuffs and fuel for household use is important in protecting female-type households, especially those in the lowest quintiles and with children, from bearing an otherwise disproportionate share of the tax burden. In contrast, high taxes on alcohol, tobacco, and fuel for private transport result in a larger incidence on male-type households. The study also suggests ways in which the indirect tax structure could be refined to further reduce the large gender (and income) inequities that exist in South Africa.  相似文献
