In this article we analyse the determinants of temporary employment through a balanced panel of workers from 1995 to 2000. First, we estimate a panel with 1267 individuals with ages ranging from 16 to 65 years. We obtain that the probability of having a temporary contract increases for people younger than 46 years old. Secondly, we estimate separately the sample of people younger than 46 years old and we obtain that the probability of temporality increases for young people with university level of education. More interestedly, the probability of being in a temporary contract is smaller for young women that for young men in Spain. 相似文献

This study empirically examines the short- and long-run dynamic causal linkages between Malaysia and its major trading partners (the United States, Japan, Singapore, China, and Thailand) based on a two-step estimation, Autoregressive distributed lag (ARDL) and Generalized Method of Moments (GMM) during the period 1992–2008. The study documents that the stronger the trade ties among the countries, the higher the degree of comovements among their stock markets. The Japanese stock market, to some extent, is found to be more important than the United States over these markets. In designing stock market policies, each country should take into consideration of any shocks in its major trading partners. 相似文献

This study examines the relationship between firm diversification strategy and R&D intensity for a sample of large French companies between 2008 and 2012. Applying quantile regression, we provide evidence that the choice of diversification affects R&D intensity in a differentiated way. The results indicate that a low level of diversification (below the twentieth quantile) has no significant impact on R&D intensity. Conversely, a moderate or high level of diversification has a negative and significant impact on R&D intensity. These findings suggest that R&D intensity seems to be significantly higher in related-business firms than in unrelated-business firms. 相似文献

民营企业是专业化发展还是多元化经营,一直困扰着民营企业家。文章认为,目前中国的民营企业正在分化为两大趋势:一部分企业坚守岗位,深化自己产业的深度、纵度、精细化;另一部分企业则开始朝着多元化趋势发展。应根据企业规模、企业在本产业的发展潜力等具体情况,决定发展模式。 相似文献

Zhagana Agriculture-Forest-Animal Husbandry Composite System (ZCS) is the first Globally Important Agricultural Heritage Systems site in the Tibetan Plateau. Similar to many traditional agricultural regions, with the development of tourism and leisure agriculture, the peasant households in ZCS have gradually changed their livelihood strategies and livelihood activities in the past 10 years, resulting in the disappearance of some traditional farming methods and agricultural landscapes with a long history. By taking livelihood assets as the entry point and livelihood strategies as the core, this paper analyzed the basic situation of households’ livelihood and the transition mechanism of different livelihood strategies in order to offer suggestions for the dynamic conservation and sustainable development of Agricultural Heritage Systems (AHS). (1) The livelihood strategies of peasant households in ZCS can be divided into two major categories: specialized strategies and diversified strategies. (2) According to the empirical calculation of the livelihood asset accounting framework of AHS, the average livelihood asset value of peasant households in ZCS is 2.040, showing that the situation of peasant households’ livelihood is inadequate. (3) The transition of peasant households’ livelihood strategies from traditional strategy to specialized or diversified livelihood strategies is mainly influenced by natural assets, human assets, cultural assets, social assets and informational assets. In order to meet the growing material and spiritual needs of peasant households and achieve the sustainable development of ZCS simultaneously, it is suggested that the agriculture-forestry-animal husbandry-tourism composite strategies shall be taken as the development direction of peasant households’ livelihood strategies. 相似文献

Despite the increase in institutional ownership, decreased trading costs, and increased real personal savings, we find that the average stock price is lower today than it was in the 1920s. In the aggregate, the propensity to split is a function of recent market performance, personal savings, and the desirability of appearing to be a small firm. Our results indicate that, after decades of inflation and the average stock price falling, splitting stocks to return to an "affordable" trading range must be rejected as an explanation. This suggests that other economic forces are behind splits, whether traditional or behavioral in nature. 相似文献

This paper uses the genetic algorithm (GA) approach to generate a portfolio optimisation scenario of a South African investor who seeks to maximise return from investing in S&P500, FTSE100, NASDAQ, DOWJONES, CAC40 and the DAX from January 1, 2005, to January 31, 2008, but facing exchange rate risk. The GA searches for the optimal solution in the entire set of financial constraints without looking for partial derivatives of the utility function. Whereas most financial problems require a non‐linear and time‐varying model, the GA, with its survival principle of offspring chromosomes, is better suited to this type of problem than local optimisation methods. The performance of the GA is compared with two non‐linear models, namely the quadratic mean‐variance (QMV), which maximises the portfolio mean‐variance, and the quadratic variance minimisation (QVM), which minimises the portfolio variance. The results show that neither the QMV nor the QVM takes into account the domestic investors' risk attitude towards investing in foreign equities and therefore does not provide any international diversification benefits. In addition, the bootstrapping scenario of 10,000 simulations reveals that neither the QMV nor the QVM outperforms the GA in terms of Sharpe ratio and flexibility in dealing with investors' risk attitude towards investing in foreign equities denominated in foreign currencies. 相似文献

I quantify the effects of conglomeration on credit risk by first computing theoretical default probabilities for conglomerates and their hypothetical stand‐alone counterparts and then mapping them into physical probabilities using a comprehensive database of corporate failures. Comparing the credit risk of conglomerates with that of hypothetical stand‐alone firms, I report significant reductions in the annual probability of default for small firms. My results support the proposition that managers can have a strong incentive to engage in conglomeration, even if it reduces shareholder value and show for which firms this is the case. 相似文献

从企业管理者、股东和债权人之间的利益分配关系看,目前我国还没有建立起一个以债权人为主导的企业筛选机制。建立和完善企业筛选制度,不仅是我国市场化进程中的一个重要环节.是实现资源市场化配置的必然渠道,而且是不良资产清算的制度保证:不良资产的多样化出售的目的主要是最大限度地以最高价格出售不良资产,为此需要在信用增级、公开操作原则、间接出售方式和完善的市场环境支持出售等各个环节上进行创新:“债转股”是常规不良资产清算手段难以奏效而破产清盘损失又太大时债务重组的最后一招.中国是典型的“政策型”债转股,并因此而生成了不少实施风险。中国的债转股要取得成功.一要建立健全资产管理公司的激励和约束机制,二要全力提高资产管理公司的能力.使其有动力也有能力高效率地完成任务。 相似文献

Gross stocks of foreign assets have increased rapidly relative to national outputs since 1990, and the short-run capital gains
and losses on those assets can amount to significant fractions of GDP. These fluctuations in asset values render the national
income and product account measure of the current account balance increasingly inadequate as a summary of the change in a
country's net foreign assets. Nonetheless, unusually large current account imbalances, especially deficits, should remain
high on policymakers' list of concerns, even, for the richer and less credit-constrained countries. Extreme imbalances signal
the need for large and perhaps abrupt real exchange rate changes in the future, changes that might have undesired political
and financial consequences given the incompleteness of domestic and international asset markets. Furthermore, of the two sources
of the change in net foreign assets—the current account and the capital gain on the net foreign asset position—the former
is better understood and more amenable to policy influence. Systematic government attempts to manipulate international asset
values in order to change the net foreign asset position could have a destabilizing effect on market expectations. JEL no.
