公司治理前沿研究综述——大股东控制、隧道行为、隐性收益与投资者保护

本文回顾了公司治理领域关于大股东控制问题的最新研究成果,主要包括大股东控制存在的普遍性、大股东控制权与现金流权的分离模式、大股东控制的激励效应和隧道效应,以及投资者保护问题等。梳理了该领域的研究脉络,并对主要发现和结论进行了总结和评论。文献研究表明,股权集中的内在机制在于大股东有动力和机会增加所有股东都可以获得的共享收益,而且大股东可以通过消耗公司资源来获得小股东无法分享的控制权隐性收益,并导致企业价值的下降。高效的投资者保护机制能够在一定程度上抑制大股东侵害小股东利益的隧道行为,提升企业价值。     

基于时变β的基金绩效评价方法及实证研究

无论对投资者还是基金公司证券,投资基金的绩效评价具有重大意义。评估基金的投资绩效,不仅要考察基金的平均收益率,而且要看它承受的风险。本文利用我国基金市场数据样本,在考虑基金贝塔系数时变的情况下构造TVB指标,并且通过实证研究,对比出这种对基金绩效评价方法的优越性。     

中华经济圈上市公司审计报告比较研究

本以中华经济圈上市公司审计报告为研究对象，分别就大陆、香港、台湾三个地区审计报告的内容与格式加以比较研究。两岸三地在审计观念、独立审计规范性质、审计责任和执业关注等多个方面的差别是形成大陆、香港和台湾地区上市公司审计报告差异的主要原因。因此，合理地借鉴港台地区审计报告体系先进的做法，全面改革和完善大陆审计报告体系和独立审计规范体系，将是我们积极迎接审计市场国际化的必要措施。     

Pure joint production and international trade: a note

This paper applies the principles of the neo-Ricardian (or Sraffian)theory of international trade to certain joint production systems.It is shown that, in contrast with single-product systems, (i)there is not always a pattern of international specialisation,which would entail the increase of the real wage rate in botheconomies, and (ii) the ‘law of comparative advantage’has no general validity. Furthermore, not only the existenceof such a pattern of specialisation but also the validity ofthis law depend on the values of the variables of distributionof income. The analysis is wholly based on two of the numericalexamples formulated by Bidard in 1997, and further generalisedin an elementary way only when this is considered necessary.     

Taxation, growth, and the spirit of capitalism

This paper uses a general two-sector model of endogenous growth to examine how the spirit of capitalism affects the relation between public finance and growth. The spirit of capitalism is defined as acquisitive personal objectives. We find that if the spirit of capitalism is present, an increase in the share of government spending in output reduces the long-run growth rate. The negative relationship between fiscal spending and growth is consistent with empirical evidence.     

Learning-by-doing and input demand of a rate-of-return regulated firm

The significance of learning by doing to input demand of a cost-minimizing rate-of-return-regulated firm is examined. Using a panel data, the results indicate that the firm's cost and input demand decisions are both influenced by learning-by-doing. The firm's cost and the rate-base (capital) input requirements decline as learning-by-doing measured by cumulative production expands. However, LBD may have different effects on the non-rate-base inputs (labor and fuel) considered in this study. While LBD ambiguously reduces fuel usage, it moderately increases labor employment. In addition to changing input intensity, LBD also influences returns to scale and elasticity of substitution.     

Bitcoin price and its marginal cost of production: support for a fundamental value

This study back-tests a marginal cost of production model proposed to value the digital currency Bitcoin. Results from both conventional regression and vector autoregression (VAR) models show that the marginal cost of production plays an important role in explaining Bitcoin prices, challenging recent allegations that Bitcoins are essentially worthless. Even with markets pricing Bitcoin in the thousands of dollars each, the valuation model seems robust. The data show that a price bubble that began in the Fall of 2017 resolved itself in early 2018, converging with the marginal cost model. This suggests that while bubbles may appear in the Bitcoin market, prices will tend to this bound and not collapse to zero.

Income inequality,unemployment, and poverty in Nigeria: a vector autoregressive approach

The main features of poverty are low levels of consumption and income, a fact‐of‐life in most African countries. This paper analyzes the fundamental trends of per capita income, government capital expenditure, the human development index, and the rate of unemployment in the Nigeria. A vector autoregressive model finds that: A reduced unemployment rate improves human development and consequently reduces poverty. As growth in public capital expenditure rises, unemployment falls and the human development index improves. Therefore, infrastructure‐based policies, which initially reduce unemployment, will also improve the living conditions of Nigerians in the end.
