本文实证考察了2005-2015年金融投机和实需对国际大宗商品现货价格的影响及其作用机理。首先对具有信息噪音属性的金融投机进行了明确识别。其次,从多个维度出发区分市场信息摩擦状态,定量分析不同信息摩擦环境中金融投机和实需的影响差异。研究发现:大宗商品价格在长期中由实需因素主导,短期中由金融投机主导;短期中,相对于低信息摩擦环境,在市场波动性较高、金融压力上升以及投资者情绪高涨的高信息摩擦环境中,以金融投机为主的信息噪音对大宗商品价格的影响更强。进一步分析证实,相比于低信息摩擦环境,高信息摩擦环境中金融交易者的市场份额反而降低。据此,本文提出稳定大宗商品市场的关键在于提高市场透明度,减少信息摩擦,从市场质量出发降低信息噪音的影响。  相似文献

国家明确以税收优惠的形式鼓励和引导企业和个人参加企业年金计划,并于2014年实施了个税递延政策。基于指标模型构建和数据模拟,本文对我国企业年金在个税递延政策实施前后的保障水平进行了比较,通过参数敏感性分析考察了投资收益、工资增长、退休年龄和缴费比例等因素的影响。研究发现,实施个税递延政策后企业职工的养老保障水平在较大程度上低于政策实施前,但不同性别、不同收入水平和不同缴费比例的企业职工保障水平降低的程度有所差异。收入水平和缴费比例越高的男性职工,个税递延政策实施后保障水平降低的幅度越高,但对女性职工而言,这种影响要弱一些。进一步,可以通过增加投资收益、延迟退休年龄和提升缴费比例等方法来提高企业职工的养老保障水平,这与目前正在进行的一系列改革方向也一致。  相似文献

We study the impact of progress feedback on players' performance in multi-contest team tournaments, in which team members' efforts are not directly substitutable. In particular, we employ a real-effort laboratory experiment to understand, in a best-of-three tournament, how players' strategic mindsets change when they compete on a team compared to when they compete individually. Our data corroborate the theoretical predictions for teams: Neither a lead nor a lag in the first component contest affects a team's performance in the subsequent contests. In individual tournaments, however, contrary to the theoretical prediction, we observe that leaders perform worse—but laggards perform better—after learning the outcome of the first contest. Our findings offer the first empirical evidence from a controlled laboratory of the impact of progress feedback between team and individual tournaments, and contribute new insights on team incentives.  相似文献

This study proposes and tests a model that incorporates two competing theories of political trust, institutional trust and cultural trust, to examine community support for “red tourism” development. Using data gathered from residents living in close proximity to Jinggangshan Scenic Area in China, this study examines the influence of authoritarian values, particularly as they relate to level of residents’ power, their level of trust in government, and their effects on support for “red tourism.” Findings suggest that trust in central government moderates the relationship between trust in local government and support. Future studies should utilize the institutional trust framework to assess residents’ trust in the local government and the cultural trust framework to assess trust in the central government.  相似文献

Corporate governance disclosure has seen renewed interest by researchers, policy makers, and regulating bodies internationally, but has remained only an emerging construct in Nepal. The primary purpose of this study was to assess the extent of mandatory corporate governance disclosure in Nepal. The secondary purpose was to examine the associations between the extent of disclosures and five firm-specific characteristics. The third purpose was to assess the significant determinants to explain variations of disclosures. The study's sampling frame consisted of 125 banking and finance companies listed on Nepal Stock Exchange. A sample size of 59 companies was randomly selected. On average, companies disclosed 91% of items in the mandatory category, 48% in the voluntary category, and 74% in total. A significant positive correlation existed between governance disclosures and firm characteristics of size, leverage, and foreign ownership. There was no significant relation between governance disclosure and listing age or profitability. With regards to determinants, bank size was a significant predictor of governance disclosure. Three regression models for total disclosures (DScore), mandatory disclosures [DScore (M)], and voluntary disclosures [DScore (V)] with three predictors of size, leverage, and foreign ownership were significant and explained 47%, 24%, and 54% variations respectively in total, mandatory, and voluntary corporate governance disclosures in Nepal. This research provides guidelines to policy makers and standard setters for developing future regulations and accounting policies.  相似文献

This paper surveys the theoretical literature investigating the effect of firms’ investment flexibility on the cross‐section of expected stock returns. Real options analysis derives firms’ value‐maximizing investment policies as functions of exogenous fundamental drivers of profitability and calculates firms’ market values as functions of the same variables. These functions yield the relationship between expected stock returns and firm fundamentals. Several plausible explanations for the value premium – the high average stock returns earned by firms with high book‐to‐market ratios – emerge from this literature.  相似文献

Applying fixed-effects panel data, this study investigates the impact of U.S. dollar exchange rate movements during different exchange rate states (overvaluation and undervaluation) on the monthly real gross and real net purchases of foreign equities by U.S. residents over the post-Plaza Accord period. The foreign equities come from 22 developed and 25 developing countries. Previous research has posited two alternative hypotheses regarding the relationship between exchange rates and foreign investment. These are the wealth effect and the profit-oriented effect. The evidence herein suggests that these two hypotheses coexist. We find robust evidence for a negative relationship between the exchange rate movements of an undervalued U.S. dollar and the demand for foreign equities. For developed countries, the wealth effect dominates the profit-oriented effect when the U.S. dollar is overvalued, while, for developing countries, the profit-oriented effect dominates the wealth effect. The results emphasize the importance of considering exchange rate states derived from a relative PPP equilibrium when analyzing U.S. allocations to foreign equities. The findings with respect to the macroeconomic control variables are mainly in agreement with the predictions of international financial theory. Some of the results, however, disappear or become inconclusive for the period after the bankruptcy of Lehman Brothers. This may be explained by the increased uncertainty in international financial markets following this unprecedented event. The findings are robust with respect to different constructed equilibrium exchange rates.  相似文献

In the wake of the recent financial and debt crises, the conduct of macroeconomic policies in the emerging MENA economies has recently become critical in determining those countries future economic situation, due to the accumulation since the early 1990s of a sizable level of external debt, and the pursuit by some countries of a fixed exchange rate regime. Using time series econometric models, this study assesses the sustainability of macroeconomic policies in a selected sample of 4 MENA countries. The empirical results point to sustainable fiscal and exchange rate policies in Tunisia and Morocco, and unsustainable external debt and exchange rate policies in Egypt and Jordan. While Egypt has recently moved to a flexible exchange rate regime, if Jordan still opts for maintaining a fixed exchange rate arrangement, it will have to implement crisis-prevention measures, namely by exercising fiscal discipline, and managing properly its external debt and foreign reserves.  相似文献

货币政策支持实体经济高质量发展的关键在于疏通货币政策传导机制,引导流动性进入重点领域和薄弱环节,因此货币资金的配置效率至关重要。本文基于交互效应面板分位数回归,测度货币政策对实体企业流动性的异质性效应。研究发现:在样本期内,实体经济流动性配置陷入了资金越充裕的企业越易于获得融资,越易于获得融资的企业资金越充裕的窘境。这种流动性配置的“马太效应”具体表现为,货币政策对尾部企业的支持力度不及头部企业的一半;虚拟经济对尾部企业的“分流效应”高达头部企业的3倍,从而强化了流动性配置的失衡。因此,当前密集出台的一系列普惠政策有助于提升流动性配置效率,进一步完善调控模式的关键在于健全现代化金融体系,增强货币政策的靶向性和针对性。  相似文献
