This paper examines the household retirement saving decisions in what concerns to the ownership of Individual Retirement Accounts (IRAs) in eight European Union (EU) countries. IRAs are more and more seen as an alternative to public pension benefits, which are decreasing. Therefore, understanding the enrolment in IRAs, both the socio-economic factors and over time, is most important. Detailed empirical analysis of the factors that might influence the ownership of IRAs is presented based on Survey of Health Ageing and Retirement in Europe (SHARE), using data from Wave 2 (2006–2007) and Wave 4 (2010–2011). Further, to analyse the impact of legal retirement age in the ownership of IRAs, two subsamples are considered: people aged between 50 and 64 years old (50–64 years) and people aged 65 or over (≥ 65 years). The results suggest that age, years of education, income and ownership of dwelling influence positively and significantly household saving, while number of children, marital status and risk aversion have a negative effect. Marital status and income are not statistically significant for retired people. Policy implications are derived. 相似文献

This article investigates the causal impact of oil prices on stock prices in each G7 market as well as in the world market. An asymmetric causality test developed by Hatemi-J is used for this purpose. Since the underlying data appears to be non-normal with time-varying volatility, we use bootstrap simulations with leverage adjustments in order to produce more reliable critical values than the asymptotic ones. Based on symmetric causality tests, we find no causal effect of oil prices on the stock prices of the world market or any of the G7 countries. However, when we apply an asymmetric causality test, we find that increasing oil prices cause stock prices to rise in the world, the U.S. and Japan while decreasing oil prices cause stock prices to fall in Germany. This may imply that the world, the U.S. and Japanese stock markets consider increases in oil prices as an indicator of good news as this may mean that there is an increase in oil demand due to an expected growth in the economy while the German stock market treats decreasing oil prices as a signal of an expected contraction in the economy. 相似文献

Suppose we know the utility function of a risk averse decision maker who values a risky prospect X at a price CE. Based on this information alone I develop upper bounds for the tails of the probabilistic belief about X of the decision maker. In the paper I also illustrate how to use these expected utility bounds in a variety of applications, which include the estimation of risk measures from observed data, option valuation, and the
study of credit risk.

This paper analyses the impact of several factors on the use of renewable energy sources in a set of European Union countries,
by applying a quantile regression approach. We find that different factors are effective for different levels of renewable
energy commitment and the magnitudes of some effects evolve in accordance with the level of renewable energy sources used.
Consequently, some policies that do not take into account the different stages could carry different effects. The results
suggest that the lobbying effect of the established industries hampers the development of renewable sources, and that this
effect is greater for lower initial level of renewable energy use. The results reveal that environmental concerns have not
yet achieved enough pressure to stimulate major developments on renewables. We include two new drivers, geographic area and
European Union Directive 2001/77/EC. That Directive was effective in signaling the commitment to renewables, namely for countries
with lower renewables use. 相似文献

This paper analyzes the relationship between public and private investment in developing countries. We set up a simple theoretical model where two countervailing forces coexist. On the one hand, public investment raises the marginal productivity of private capital and leads to potential crowding-in of private investment. On the other hand, weak institutions and restricted access to financing could diminish the positive effects of public investment projects and crowd-out private investment. The empirical results - which exploit both the time series and cross sectional variation in the data using a panel of 116 developing countries with annual observations between 1980 and 2006 - suggest that on average the crowing-out effect dominates. Moreover, we find that this crowing-out effect is dampened (or even reversed) in countries with better institutions - where the marginal productivity of public investment is conceivably higher - and that are more open to international trade and financial flows, such that financing constraints are less binding. 相似文献

In the last two decades, the economic and political world was radically transformed. At the start, in the 1980s, the USA and the USSR ruled, in a bipolar context. But, after the fall of the Communist regimes, in the 1990s, a different form of world power sharing emerged, in which the USA, the European Union and Japan were the major players. That change was evident from the documents that were made by those political powers (i.e. the Lisbon agenda on human resource development (HRD)), which in itself contained a forecast of the world situation in 2010. However, life is by nature unpredictable, and the unforeseeable changes happen all the time. And, in the last decade, several main players emerged in the world scene, namely Brazil, Russia, India, China, the Arab World and Africa. In consequence, at the present moment, the world economy exists around at least 9 main players, 3 old and foreseen and 6 new and not foreseen. It is the author's opinion that this societal transformation should be addressed by the HRD community, because HRD scholars must study the more national relevant cases in a world that is changing very fast. Accordingly, in this paper, the author tries to make a rather introductory study in which he/she tries to define the basic economic variables for the HRD markets, namely demand, supply, need, equilibrium, investment, stock, flow, and return, for the USA, Japan, Brazil, Russia, India and China. The author uses the last available data, even if we tried to put the analysis in a historical perspective. The author concludes that several very different forms of situations exist in the HRD markets of those very important political entities. 相似文献

This paper focuses on the topic of “soft skills” as an intrinsic part of successful leadership. The first part of the paper presents a literature review about the shift in perspective in recent years on what matters in leadership, and the significant changes this prompted in some areas of education and corporate recruitment. In the second part, the findings of a year round study conducted among Los Angeles based workforce members in an MBA program are presented. By utilizing a multi-method approach, consisting of a survey model with three open ended, interview style questions, and data analysis in phenomenological trend, a number of interesting findings emerged, supporting the literature reviewed, that soft leadership skills, such as self-awareness, self-regulation, motivation, empathy, and social skills, are steadily on the rise, and that greater attention should be apportioned to strengthen these skills in future leaders. 相似文献

The main purpose of this study is to determine the Critical Success Factors (CSF) of Brazilian business incubator management and understand how they are structured. These factors are essential to improve the performance of these Brazilian businesses and to strengthening the Brazilian entrepreneurial ecosystem. The strategy used was survey, and the data obtained were analyzed using the statistical technique of Exploratory Factor Analysis. The validated CSF were grouped into seven constructs. Thus far, the literature does not present any article within the scope proposed here. Additionally, the statistical technique used here is applied for the first time in this theme. 相似文献

AbstractObjectives: We used a systematic review and meta-analysis to analyze the difference in costs between surgery for frail and non-frail elderly patients. The opportunity cost of frailty in geriatric surgery is estimated using the results.Methodology: Two literature reviews were carried out between 2000 and 2019: (1) studies comparing total hospital costs of frail and non-frail surgical patients; (2) studies evaluating the length of hospital stay and cost for surgical geriatric patients. We performed a meta-analysis of the items selected in the first review. We subsequently calculated the opportunity cost of frail patients, based on the design of a cost/time variable.Results: Twelve articles in the first review were selected (272,717 non-frail and 16,461 frail). Fourteen articles were selected from the second review. Frail patients had higher hospital costs than non-frail patients (22,282.541 € and 16,388.844, p?<?.001) and a longer hospital stay (10.16 days and 8.4 (p?<?.001)). The estimated opportunity cost in frail patients is 1,019.56 € (cost/time unit factor of 579.30 €/day).Conclusions: Frail surgical geriatric patients generate a higher total hospital cost, and an opportunity cost arising from not operating in the best possible state of health. Preoperatively treating the frailty of elderly patients will improve the use of health resources 相似文献

The purpose of this paper is to contribute further insights into individuals’ agri-environmental attitudes. In particular,
the empirical analysis focuses on how citizens think agri-environmental property rights should be assigned. This has been
done by surveying how individuals consider the environmental policy should promote the implementation of a group of agri-environmental
measures, allowing us to examine the determinants of individuals’ opinions about this matter. Results indicate that higher
level of income and education support the implementation of obligatory agri-environmental measures with no financial support
(property rights should rest on society) except for measures to improve public access to land for leisure activities and ecological
farming which are seen more of the voluntary kind (property rights should rest on farmers). Additionally, rural residency
has strong significant effect on agri-environmental attitudes as rural residents are more likely to support the implementation
of voluntary (with/without financial support) agri-environmental measures. On the whole, this research proves to be a valuable
tool to identify factors determining individuals’ attitudes towards agri-environmental property rights which can certainly
help policymakers to provide customized, better response to social demands on this matter. 相似文献
