作为国有企业产权改革主要模式,“混合所有制”改革是否有助于确保国有资产保值增值,是否有助于推动中国经济可持续发展等问题仍存在探讨空间。本文基于对于改革开放以来中国国有企业改革的成就和教训的考察,指出“混合所有制”可以作为竞争性部门国有企业改革的一个过渡形式;对于垄断央企的改革应该充分借鉴国际上自然垄断行业的改革经验,打破行政垄断,推动竞争性框架建立,并切实实现从“管企业”逐步调整为“管资本”,通过改革实现国有资产的保值增值,并为经济创造新的增长点。 相似文献

The post‐2001 financial crisis era in Turkey gave rise to twin booms in housing construction and credit markets, both of which suffered from the subsequent debt crisis. The financial transformation of the economy in conjunction with state‐led urban legislation reform had significant effects on the housing market in terms of commodification of housing, countrywide construction activities and substantial increases in household debt and construction company loans. The changing role and function of the state as a direct provider of housing can be regarded as actually existing neoliberalism providing favourable conditions for financialization, as it ushered in the commodification of housing. The Turkish government, together with the government‐backed housing agency, metropolitan municipalities and publicly owned real‐estate investment company, has been active in nationwide housing construction and urban regeneration projects. This article argues that there is a lack of synchrony between the commodification of housing and the financialization of the household sector owing to the institutional setting of the mortgage system and structural macroeconomic problems. Rather, housing commodification has been accompanied by the financialization of the corporate sector through a steep rise in the external debt burden of construction companies. 相似文献

Based on the wavelet analysis approach, this paper firstly examines the dynamic relationship between global economic activity (proxied by the Kilian economic index) and crude oil prices in both time- and frequency-domains. Our empirical results demonstrate significant correlation between crude oil prices and global economic activity at high frequencies (in the short run) during the entire sample period; however, the co-movement between the two at low frequencies (in the long run) is weaker and exists only during certain proportions of the sample period. We also document evidence that global economic activity and oil price are positively correlated, with dynamic lead-lag relationships across time. Our findings are robust to alternative choices of oil price indexes and controlling for other confounding factors such as geopolitical risk, armed conflicts, economic policy uncertainty and equity market uncertainty. The current study provides valuable implications for oil market investors based on the information of global economic situation and its dynamic relationships with oil prices. 相似文献

We examine the impact of the introduction of VIX exchange‐traded products (ETPs) on the information content and pricing efficiency of VIX futures. We document that trades in VIX futures have become less informative and that pricing errors exhibit more persistence after the introduction of VIX ETPs. In addition, we observe that the price process of the VIX futures has become noisier over time. These findings suggest that the introduction of the VIX ETPs had a prominent effect on the properties and dynamics of the VIX futures. 相似文献

The inflation rate is a key economic indicator for which forecasters are constantly seeking to improve the accuracy of predictions, so as to enable better macroeconomic decision making. Presented in this paper is a novel approach which seeks to exploit auxiliary information contained within inflation forecasts for developing a new and improved forecast for inflation by modeling with Multivariate Singular Spectrum Analysis (MSSA). Unlike other forecast combination techniques, the key feature of the proposed approach is its use of forecasts, i.e. data into the future, within the modeling process and extracting auxiliary information for generating a new and improved forecast. We consider real data on consumer price inflation in UK, obtained via the Office for National Statistics. A variety of parametric and nonparametric models are then used to generate univariate forecasts of inflation. Thereafter, the best univariate forecast is considered as auxiliary information within the MSSA model alongside historical data for UK consumer price inflation, and a new multivariate forecast is generated. We find compelling evidence which shows the benefits of the proposed approach at generating more accurate medium to long term inflation forecasts for UK in relation to the competing models. Finally, through the discussion, we also consider Google Trends forecasts for inflation within the proposed framework. 相似文献

本文通过构建包含房产税的动态随机一般均衡(DSGE)框架,兼顾居民用房与商业用房,模拟分析房产税改革对主要宏观经济变量的影响。研究结果表明:(1)提高居民用房房产税税率对总消费、投资、房价和总产出等变量的均衡值和波动均以负面影响为主,但会降低社会福利损失;(2)降低商业用房房产税税率对总消费、投资、房价和总产出等变量的均衡值和波动均以正面影响为主,但会提高社会福利损失;(3)提高居民用房房产税税率与降低商业用房房产税税率同时实施时,不仅能够对冲居民用房房产税改革对宏观经济的负面影响,尤其是能够有效对冲改革对投资和总产出的负面影响,还会降低社会福利损失。因此,中国下一步试点改革应当重点关注组合式改革方案。 相似文献

We study the optimal execution problem with multiplicative price impact in algorithmic trading, when an agent holds an initial position of shares of a financial asset. The interselling decision times are modeled by the arrival times of a Poisson process. The criterion to be optimized consists in maximizing the expected net present value of the gains of the agent, and it is proved that an optimal strategy has a barrier form, depending only on the number of shares left and the level of the asset price. 相似文献

ABSTRACTUsing monthly panel data for China’s 30 provinces from 2007 to 2017, this article analyzes how level of financial support affects the interplay between real estate development and macroeconomic growth. Based on a threshold model, the results suggest that housing price increases substantially impede economic growth, but there is no significant threshold effect for the sample as a whole. On investigating regional cross-sectional variations, we found that local economic situation clearly impacts on this effect, with significant threshold effects detected in subsamples. While housing price may have positive influences on economic growth in the mid-west subgroup with appropriate financial support, more developed regions returned contrary results. 相似文献
