A strong private equity (PE) market is a cornerstone for commercialization and innovation in modern economies. However, substantial differences exist in the relative amounts raised and invested in PE across European countries. We investigate the macroeconomic determinants of PE investment in Europe, focusing on the comparison between Central and Eastern European (CEE) and Western European countries. Our estimations are based on a data set running from 2001 to 2011 that covers 16 countries. Applying robust estimation techniques, we identify a ‘robust’ set of determinants of PE activity in both regions. We find similarities as well as differences in the driving forces of PE investments in Western European and CEE countries. Our results suggest that economic activity, the inflation rate, equity market capitalization, unit labour costs, the unemployment rate as well the the institutional and legal environment are significant determinants of PE activity. 相似文献

This article provides an empirical strategy guided by the data to estimate the effects of Economic Integration Agreements (EIAs) on trade flows and their transitional dynamics. The strategy uses Extreme Bounds Analysis (EBA) to guide the choice of lags and leads in the effects without researchers' discretion involved. We show that arbitrarily selected year intervals and starting year can result in non-robust estimates of transitional dynamics of the effects of EIAs on trade flows. The empirical strategy follows two steps: EBA first sifts lags and leads of EIAs robustly related to trade flows from candidates, then these are included in the gravity equation to estimate the effects of EIAs on trade. We find that various lags and leads are robustly and positively related to trade flows, and the lag and lead structure depends on the level of integration. Our results show that EIAs have a long-term effect of 63% on trade flows. Under the richer lag and lead structure, deep-integration agreements beyond the level of free trade agreements have a much higher impact on trade flows than free trade agreements do (132% vs 31%). The estimates of effects of EIAs obtained from EBA-based estimation have a smaller contemporaneous effect and larger phased-in effects compared to previous studies relying on the subjective choices of year intervals while similar results are observed with the decomposed EIAs. 相似文献

By decomposing complex issues into factors at all levels, Grey Relativity Analysis (GRA) can effectively calculate the degree the main factors affect the goal value, and overcome the problems that the traditional mathematical statistics have such as big samples, heavy computation, and inconsistency between quantitative results and qualitative analysis. So it becomes one kind of simple, convenient and distinctive systematic analysis method. GRA is applied to corporate crisis early warning analysis. The paper through the GRA the half of this quantitative approach, explores the correlation degree among the corporate crisis early warning factors, in order to find the importance sequence of instance enterprise early warning crisis factors by calculation so as to provide a theoretical foundation for the prevention and decrease of the instance enterprise crisis. 相似文献

The OECD proposes to kill two birds with one stone in Russiaby simultaneously improving fiscal federalism, and using thefinancial reform process to press for full market liberalisation.This paper scrutinises the initiative and finds it wanting becausethe consensus reforms advocated conflate the re-centralisationof fiscal authority with optimal ownership, property rightsand effective market building, perpetuating the illusion thatthere are no bad market systems. The G-7 and Putin must do better.Yeltsin's mis-privatisation and mis-liberalisation, which spawnedrent seeking, asset stripping, asset seizing and a disregardfor profit maximising from current operations, have proved tobe path dependent and need to be rectified. Putin's increasinglyvisible efforts to rein private property rights must also betaken into account in designing on optimal fiscal federalistregime. 相似文献

我国政府支出对人类发展指数影响的经验分析 总被引:3,自引:0,他引:3
文章用我国国家财政支出和预算外支出度量政府支出,计算出政府支出的增长率作为我国财政政策变动的代理变量,用我国的人类发展指数度量人类发展状况.对数据整理后,形成政府支出增长率和人类发展指数变动的时间序列.使用计量经济学的方法考察了政府支出变动对人类发展指数变动的影响,在借鉴其他学者对政府支出和经济增长关系研究成果的基础上,得出的基本结论是:在1990-2003年间,我国财政政策的变动和人类发展指数的变动没有显著的相关关系,二者之间也不能相互解释,我国财政政策依然是以拉动经济增长为政策偏向的,考虑财政政策变动的时滞,发现其对我国人类发展指数的影响为负. 相似文献

This paper develops a composite Financial Sector Stress Index (FSSI) for the Indian financial system as a whole by combining three sub-indices for currency markets, the banking sector and the stock market, to gauge the level of financial stress in the Indian financial system. Such a continuous-valued index can be used to track the varying magnitude and dynamics of financial stress in the country over time. The FSSI provides an ordinal measure of stress in the financial system. Changes in the FSSI are useful in assessing whether financial stress is rising or falling, and in ascertaining extreme events in the financial system. The paper, then, objectively identifies extreme stress periods in the financial system based on movements of the index. We recognise that such extreme/tail events pose special econometric challenges as they are rare events but with a big impact. Hence, we use a more robust and analytically sound technique of Extreme Value Theory (EVT) to identify extreme events in the financial system. Once the extreme stress events are identified, we use a binary dependent variable model (logit model) to estimate the impact of various macroeconomic and financial variables on the probability of extreme stress in the financial system. 相似文献
