企业股权结构与股权转让效率——以中国大陆A股上市公司为例

通过对中国大陆A股上市公司股权转让数据的分析表明,企业股权转让更容易发生在股权较为分散的公司中,但是股权转让后的企业效率并没有明显的改善,公司控制权的转移往往对企业绩效产生负面的影响。由此可见,通过鼓励企业股权结构分散化并对控制权私人收益加以必要的管制,对提高股权转让的效率将起到非常重要的作用。     

Does lending behaviour of banks in emerging economies vary by ownership? Evidence from the Indian banking sector

While much has been discussed about the relationship between ownership and financial performance of banks in emerging markets, literature about cross-ownership differences in credit market behaviour of banks in emerging economies is sparse. Using a portfolio choice model and bank-level data from India for 9 years (1995–96 to 2003–04), we examine banks’ behaviour in the context of credit markets of an emerging market economy. Our results indicate that, in India, the data for the domestic banks fit well the aforementioned portfolio-choice model, especially for private banks, but the model cannot explain the behaviour of foreign banks. In general, allocation of assets between risk-free government securities and risky credit is affected by past allocation patterns, stock exchange listing (for private banks), risk averseness of banks, regulations regarding treatment of NPA, and ability of banks to recover doubtful credit. It is also evident that banks deal with changing levels of systematic risk by altering the ratio of securitized to non-securitized credit.     

Supply Chain Management as Private Sector Regulation: What does it Mean for Business Strategy and Public Policy?

The growing practice of environmental supply chain management by firms constitutes private sector regulation that is analogous in many ways to public sector regulation. Similarly to their public counterparts, private sector regulators set standards, apply standards, monitor for compliance, apply sanctions and require corrective action. Private sector regulation differs, however, in the source of authority, external oversight, analytical requirements, public participation and available sanctions. This article argues that supply chain management by firms goes beyond business objectives by creating positive environmental externalities for society, and that more systematic study of the similarities and contrasts between the two forms of regulation may provide valuable lessons for both. Further, it may be possible to increase the effectiveness of private sector regulation to achieve both public societal and private business goals. From a business perspective, supply chain management enables firms to strategically redefine their relationships with government, reduce uncertainty and promote goal‐oriented collaboration.

转型期我国股票市场规制目标的选择

"为国有企业筹资、推动国民经济增长"这一政府股票市场规制的目标已经不能适应经济发展的要求,监管当局应该将"加强投资者利益保护"作为股票市场规制的核心目标,以进一步推进中国股票市场的可持续发展。保护投资者利益是股票市场政府规制目标的核心。造成我国股票市场投资者保护机制缺失的制度性基础在于政府一身兼三职的制度安排,即政府既是国有上市公司、证券交易所、证券公司的实际或者变相的终极所有者,又是投资者利益的守护神,同时也是证券市场的规制与监管者。     

Regulation of road accident externalities when insurance companies have market power

Accident externalities that individual drivers impose on one another via their presence on the road are among the most important external costs of road transport. We study the regulation of these externalities when insurance companies have market power. Some of the results we derive have close resemblance to the earlier literature on externality regulation with market power in aviation and private roads, but there are important differences, too. Using analytical models, we compare the first-best public welfare-maximizing outcome with a private profit-maximizing monopoly, and oligopoly. We find that insurance companies will internalize some of the externalities, depending on their degree of market power. We derive optimal insurance premiums, and regular parametric taxes as well as “manipulable” ones that make the companies set socially optimal premiums. The latter take into account that the firm tries to exploit knowledge of the tax rule applied by the government. Finally, we also study the taxation of road users rather than that of firms.     

THE REGULATION OF PRIVATE SCHOOLS SERVING LOW‐INCOME FAMILIES IN HYDERABAD,INDIA: AN AUSTRIAN ECONOMIC PERSPECTIVE1

It is the intention of government that private schools in Hyderabad are prevented by regulation from exhibiting the basic manifestations of competitive markets ‐ low prices, innovation, good service and so on. However, private schools do, in practice, manifest these features. This paradox is resolved because regulations are not enforced in practice, with the acceptance of bribes by government officials being common. As a result of ‘extra‐legal’ activity, private schools are able to offer a better service to the poor than if regulations had been enforced.     

Are regulations the answer for emerging stock markets? Evidence from the Czech Republic and Poland

Does the emergence of a stock market require a well-developed legal and/or regulatory system? Although historical work by Neal and Davis [Neal, L., & Davis, L. (2005).

They maintain that the Warsaw Stock Exchange, which is seen as more regulated, has outperformed the Prague Stock Exchange which is seen as largely unregulated. Thus increased regulations are a key to increased performance. This article, however, maintains that the evidence from the Czech experience has been misinterpreted. This article provides an in depth case study of the Czech stock market and finds that (a) Czech capital markets have been hindered by government intervention from their beginning, (b) that the evidence on Poland's superior performance is not as strong as suggested, and (c) that Czech regulators seem to be unqualified, lack the proper incentives, and are unlikely to benefit the market. Under these circumstances it appears that Neal and Davis (2005:311) are correct that increased government involvement is unlikely to improve the situation.     

Incremental vs. Comprehensive Reform of Economic Regulation: Predictable Outcomes and Unintended Consequences

A bstract . Examination of the theory and politics of reform of government regulatory policy leads to the conclusion that comprehensive reform of economic regulation is desirable and possible, given that we understand how existing regulatory decision-making processes operate and how reform efforts in the past have failed. Options exist along a dimension of magnitude of change: incremental versus comprehensive reform. Under certain conditions regulatory reform is best achieved through comprehensive change and equilibration to new policy, rather than marginal adjustments to existing policy that often lead to more rather than less government regulation.
Comprehensive reform is held to be complete or nearly complete relaxation of government control over price, market entry and other aspects of competition among firms across an entire industry , or assumption by government of new , broad-scale controls over private lector market behavior. Comprehensive reduction of government control, i.e., deregulation , is in accord with the observation that government decision-makers sometimes behave as if economic efficiency were an important objective.     

Disclosure Regulation in Duopoly Markets: Proprietary Costs and Social Welfare

Abstract

The argument of proprietary costs is commonly used by firms to object against proposed disclosure regulations. The goal of this paper is to improve our understanding of the welfare consequences of disclosure in duopoly markets and to identify market settings where proprietary costs are a viable argument for firms to remain silent. We, therefore, solve the optimal disclosure strategies and distinguish two different potentially costly effects of disclosing private information: the strategic information effect and the market information effect. We identify the market settings for which a regulator prefers to impose disclosure regulation so as to maximise consumer surplus or total surplus. Regulation may be necessary because (i) the increase in welfare outweighs proprietary costs to the firms, or (ii) firms are trapped in a prisoners' dilemma. The first primarily applies to Bertrand competition with demand uncertainty and, to a lesser extent, to Cournot competition. The second applies primarily to Cournot competition and Bertrand competition with cost uncertainty.     

The European single market and the regulation of the legal profession: an economic analysis

The article analyses the effect of removing barriers between two autarkic legal markets with different technologies. Firms using the more efficient technology penetrate the other market. The result is mergers between firms from the efficient jurisdictions and those in the inefficient jurisdictions. Social welfare increases from reduced resource costs in the production of legal services even if prices remain regulated. This leads to pressure for prices for legal services to be reduced. Recent trends in the penetration of EU legal markets by English solicitors firms are discussed, particularly recent mergers involving English and German law firms. Implications for future market regulation are drawn. Copyright © 2002 John Wiley & Sons, Ltd.     

Do Market Participants Learn? The Case of the Budapest Stock Exchange

In the paper we consider one of the faster growing Central European emerging markets: the Budapest Stock Exchange (BSE), in order to see whether the market becomes more weak-form efficient over time. The Hungarian exchange is selected because it is the oldest stock exchange operating in the region and, in 1995, it was the first Central European exchange admitted by the London Stock Exchange as a properly regulated stock exchange. As an econometric tool for comparative analysis, we use a Test for Evolving Efficiency (TEE). In a comparison of nine stocks and the market index (BUX) we found that the BSE becomes more mature but the process is surprisingly slow.     

FINANCIAL REGULATION,THE STATE AND THE MARKET: IS THE FINANCIAL SERVICES AUTHORITY AN UNNECESSARY EVIL?

The most successful stock exchanges developed without detailed regulation by the state. This article examines the role of the FSA in regulating stock market activity and finds that the justification for a statutory regulator is very weak. Indeed, one of the functions of a stock exchange is the development of a safe (private) regulatory environment for those using the exchange. Stock exchanges should be allowed to compete on the basis of the regulatory services they provide as it is only through a process of competition that regulation can be improved.     

Sustainable Development,Sustainability Leadership and Firm Valuation: Differences across Europe

Sustainable development is nowadays a high priority for firms all over the world. Consequently, numerous firms have increased their social responsibility initiatives, reinforcing the credibility and trust of their stakeholders. However, prior research about the relevance of sustainability leadership for the European investment community is scarce. In this context, the aim of this study is to examine whether sustainability leadership – proxied by membership of the Dow Jones Sustainability Index Europe – is value relevant for investors on the 10 major European stock markets over the 2001–2013 period. Our overall results reveal that there exist significant differences across markets. These findings are relevant especially for investors, but also for the managers of listed firms, market regulators and policymakers. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment     

Auditor Concentration of Listed Public Companies on International Stock Exchanges

This paper explores the concentration of audit services provided to listed public companies on the Stock Exchanges of Canada, Hong Kong, London, and Singapore. The Canadian and London stock exchanges are chosen as representatives of the North American and European markets, while the Hong Kong and Singapore exchanges represent the newly developed Asia Pacific markets. Public accounting firms have benefited from the globalisation trends by expanding their own markets. The reason frequently mentioned for the mergers of the Big 8 accounting firms to form the Big 6 is that they want to increase their international presence and be in a better position to service multinationals in different markets. However, previous studies of concentration of firms in providing auditing services have all been restricted to the USA or individual countries. This study uses both concentration ratios and Herfindahl indices to examine concentration of audit firms in the international stock exchanges. The results indicate a disparate competition amongst the larger firms in each of the Canadian, Hong Kong, London, and Singapore markets. In all of the four markets, the concentration ratios and Herfindahl indices calculated indicate a lack of competition even at the four firm level. This imbalance was very pronounced when the size of the companies audited is considered using their reported total assets. We also present the market shares of the leading six firms in each exchange and discuss some implications of this disparate competition.

Real Earnings Management and Information Asymmetry in the Equity Market

The literature suggests that real earnings management (REM) activities can increase adverse selection risk in capital markets. Due to their opacity and the difficulties in understanding their implications, REM strategies may increase the level of information asymmetry among investors. This paper examines the association between earnings management through real activities manipulation and information asymmetry in the equity market. To estimate the level of adverse selection risk we use a comprehensive index of information asymmetry measures proposed by the market microstructure literature. For a sample of Spanish listed firms, we find that firms’ strategies of increasing earnings through REM are associated with higher information asymmetry in those firms that meet last year’s earnings. Our findings are consistent with the hypothesis that earnings management through real activities manipulation garbles the market, enhances private information production, and exacerbates information asymmetry in the stock market.     

Broad-based stock options: before and after the market downturn

We examine labour productivity in small, medium and large firms that broadly distribute stock options under starkly different market conditions – during the bull (1995–7) and bear (2000–2) stock markets. We find greater labour output in both upward and downward markets in all firm size categories, with the exception of small firms in a declining market, where the productivity is also greater, but the statistical significance of the result is weak.     

Should we worry about the decline of the public corporation? A brief survey of the economics and external effects of the stock market

In recent years, the number of listed companies has been declining in many countries across the world. This paper provides a selective survey of the literature on the real economic effects of the stock market to assess the potential effects of this decline and determine whether it is likely to continue. The leading economic role of the stock market’s primary market, in which firms raise capital by issuing new shares, is to help growing firms secure financing. We discuss providing and certifying information, coordinating investors, and easing the redeployment of capital as the means through which capital allocation can be efficiently achieved. The main economic roles of the stock market’s secondary market, the trade in existing shares, is to provide liquidity to shareholders, to aid in price discovery and to provide diversification opportunities. Positive external effects from an active stock market may arise for consumers, labor and private firms due to increased corporate investment, more socially responsible business strategies and a more positive business climate. Negative external effects on capital allocation and productivity can arise from short-termism, market mispricing, and increased cross-ownership. Local stock markets can spur innovation and foreign direct investment (FDI) and reduce the risk of early cross-border acquisitions. Given the myriad of useful economic functions the stock market performs, a future entirely absent of public companies is difficult to imagine and the decline is therefore likely at some point to come to an end. Whether we need to worry about the decline depends on the relative importance of the positive and negative external effects, a topic we feel warrants more research.     

Governance and stock market performance

This study uses international asset pricing models to investigate the link between the quality of government institutions and the performance of global stock markets. The results demonstrate a significant positive association between stock market performance measures and the quality of the institutional environment. Performance measures examined for the cross-section of countries were the average monthly stock index excess returns and the Sharpe ratio. All measures of performance were adjusted for global and local risk factors known to explain their international variation. The quality of governance is also found to be negatively associated with stock market total risk and idiosyncratic risk, consistent with the notion that stable institutions are linked to reduced variations in equity returns. These findings suggest countries with better-developed governance systems have stock markets with higher returns on equity and lower levels of risk. The results lend support for the view that a precondition for financial market development is the improvement of the institutions which govern the process of exchange.     

Should the government directly intervene in stock market during a crisis?

Unlike foreign exchange markets where central banks frequently intervene, the governments strive not to intervene in the stock markets since intervention transmit negative signals and carry market-related side effects. The main reasons often cited in support of intervention are to bring price stability and to restore investors’ confidence. During the recent economic turmoil, opportunities for the governments to intervene in the stock markets were mainly exploited in emerging and developing countries. We study the outcome of the Russian government's intervention in its major stock market between September and October 2008. This intervention was intended to reverse the sudden and swift declining trend in traded security prices by altering the market's expectations. By using a combination of event study and a multivariate GARCH model, our findings does not support direct government intervention in the stock market during a crisis.
