We investigate the asymmetric causal interaction between the stock markets of the GIPS (Greece, Ireland, Portugal and Spain) and those of the BRIC (Brazil, Russia, India and China) based on a newly developed asymmetric causality test by Hatemi-J (2012) [Hatemi-J, A. 2012. “Asymmetric Causality Tests with an Application.” Empirical Economics 43: 447–456. doi:10.1007/s00181-011-0484-x]. We confirm a significant stock market interaction between the two blocs in which the BRIC drives the GIPS but not vice versa. Thus, the BRIC seems to be more influential on the GIPS than the GIPS on the BRIC. However, this interaction occurs only during downmarket conditions but not during upmarket times. The BRIC pulls down the GIPS during bad times but does not pull them up during good times. These results have significant implications for international policymakers and provide further evidence on the existence of asymmetric causal interactions between financial markets. 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 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

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

This article takes a step toward understanding potential causes of wage discrimination in an economy highly dependent on the service industry. Traditionally categorized within the service industry, professional sport leagues such as the National Basketball Association (NBA) provides a unique setting to examine the potential impact of race on salary. We analyze free agency contract signings, which allow us to better capture the determinants of players' wages, from 2011 to 2017 to investigate the prominence of wage discrimination in the NBA. Using weighted linear regression models and the Oaxaca–Blinder decomposition, we find that Black athletes are paid significantly less than their counterparts. In addition, we also identify the presence of consumer discrimination after controlling the exposure of a player to the audience, which is observed through the interaction term between the share of MSA population which is White and an identifier for whether a player is Black. 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
