The dynamics of privatization, the legal environment and stock market development

In this paper, we examine under which conditions privatization is an effective means to develop local stock markets for a panel of 61 countries over the last twenty four years. By addressing the endogeneity between privatization and stock market development, we show for the 1980-98 period that the initial legal environment is a significant contemporary determinant of stock market development, while privatization is not. When we examine the dynamics of privatization in interaction with the legal environment, we find that privatization has a two-year-lagged effect on stock market development in emerging markets, and a one-year-lagged effect in developed countries. Results for the 1999-2003 period seem to be largely affected by the global crash that followed the Asian crisis.     

Effects of Passive Intensity on Aggregate Price Dynamics

We find that passive intensity (PI), measured by the passive‐linked share of total stock market trading volume, is strongly related to the overall pattern of stock price movements. A one‐standard‐deviation increase in PI is associated with an 8% higher price synchronicity. We further investigate the channels through which this relation is established by separately analyzing its impact on aggregate systematic and idiosyncratic volatility of stock returns. PI has a positive effect on systematic volatility and a negative impact on firm‐specific volatility. Consistent with the effect of passive trading on price dynamics, we find evidence that PI is negatively associated with mutual funds alpha dissimilarity. After controlling for market and idiosyncratic volatility, a one‐standard‐deviation increase in PI corresponds to a 0.20% decrease in fund dissimilarity. Our findings are robust after controlling for various macro and corporate factors known to affect systematic or firm‐specific volatility.     

Privatization,political risk and stock market development in emerging economies

This paper investigates whether privatization in emerging economies has a significant indirect effect on local stock market development through the resolution of political risk. We argue that a sustained privatization program represents a major political test that gradually resolves uncertainty over political commitment to a market-oriented policy as well as to regulatory and private property rights. We present evidence suggesting that progress in privatization is indeed correlated with improvements in perceived political risk. Our analysis further shows that changes in political risk in general tend to have a strong effect on local stock market development and excess returns in emerging economies. We conclude that the resolution of political risk resulting from successful privatization has been an important source for the rapid growth of stock markets in emerging economies.     

Privatization and stock market liquidity

This paper shows that share issue privatization (SIP) is a major source of domestic stock market liquidity in 19 developed economies. Particularly, privatization IPOs have a negative effect on the price impact – measured by the ratio of the absolute return on the market index to turnover. This result is robust to the inclusion of controls for other observable and unobservable factors, having also considered the endogenous nature of the decision to privatize.     

The Financial and Economic Lessons of Italy's Privatization Program

Since 1994 the Italian government has sold equity stakes in some 75 large state enterprises, in the process raising over $125 billion‐more than any other country during the same period. In this article, a U.S. academic collaborates with the Italian government's Director of Privatization in summarizing the accomplishments and disappointments of Italy's privatization program, assessing its impact on Italian capital markets, and offering lessons for other countries embarking on new privatization programs. The article also describes the share issuance methods used by the government to execute several massive offerings, including the largest IPO in history. The principal benefits of Italian privatization have been dramatic increases in the size and efficiency of Italy's stock markets and in the safety and stability of its banking system. Despite such improvements, however, privatization has failed to bring about the increased competition in key industries and lower prices for consumers its planners originally envisioned. And based on this experience, the authors offer a number of lessons for government planners. Perhaps most important, privatization is likely to yield decisive benefits only if the divestment program is properly designed and sequenced. Governments should begin by privatizing state‐owned banks and other financial institutions, and as quickly as economically and politically feasible. Especially in less developed economies, commercial banks are for many companies both the only suppliers of credit and the only effective source of market discipline‐which explains why results have often been disastrous when governments have retained control of banks while privatizing other industries. Privatizing governments should also emphasize privatizations accomplished through share issuances rather than asset sales, with the aim of developing liquid and efficient stock markets and promoting effective corporate governance.     

Information diffusion and the predictability of New Zealand stock market returns

This paper examines the impact of international predictors from liquid markets on the predictability of excess returns in the New Zealand stock market using data from May 1992 to February 2011. We find that US stock market return and VIX contribute significantly to the out‐of‐sample forecasts at short horizons even after controlling for the effect of local predictors, while the contribution by Australian stock market return is not significant. We further demonstrate that the predictability of New Zealand stock market returns using US market predictors could be explained by the information diffusion between these two countries.     

Does the response of competitors to privatization announcements reflect competitive or industry-wide information effects? International evidence

We examine the stock price reaction of rival firms to the announcement of the privatization of their industry counterparts to infer information about the intra-industry effects of privatization. We find that the rival firms reacted negatively to the privatization announcements, suggesting that the announcement effects reflect competitive rather than positive industry effects. The reaction is stronger for industry counterparts in low economic freedom countries than those in high economic freedom countries. Interestingly, we also find that full privatization announcements generate larger negative abnormal returns for rival firms than partial privatization announcements where the privatized firm gains only partial autonomy from the government. In this regard, we find that, as the proportion of government ownership reduces, subsequent partial privatization announcement elicits stronger market reaction from rival firms. The negative abnormal returns earned by shareholders of rival firms are not due to price pressure and portfolio rebalancing effects resulting from index composition changes. We conclude that the negative effects documented for the rival firms reflect investors' concern about the potential competitive effects resulting from privatization of the state enterprise.     

Social Interaction and Stock-Market Participation

We propose that stock‐market participation is influenced by social interaction. In our model, any given “social” investor finds the market more attractive when more of his peers participate. We test this theory using data from the Health and Retirement Study, and find that social households—those who interact with their neighbors, or attend church—are substantially more likely to invest in the market than non‐social households, controlling for wealth, race, education, and risk tolerance. Moreover, consistent with a peer‐effects story, the impact of sociability is stronger in states where stock‐market participation rates are higher.     

Credible reforms and stock return volatility: Evidence from privatization

In this paper we investigate how privatization affects stock return volatility. A credible privatization builds investors’ confidence through a reduction in political risk. In particular, a privatization program that is maintained over time signals credibility, which reduces political risk and in turn volatility. We further show that privatization is associated with lower idiosyncratic volatility mainly among developed markets, while it is associated with lower systematic volatility in developing markets. Additional tests suggest that the reduction in volatility is greater when privatization sales are carried out through the stock market than through asset sales.     

Asset Allocation Under Partial and Complete Privatization of Social Security Contributions

Social Security reform has focused on allowing individuals to choose where to invest a portion of their retirement contributions as a means of avoiding insolvency of the retirement system. Chilean reforms in the early 1980s have demonstrated, at least for a developing and immature stock market, that privatization can be an effective way to increase returns on retirement savings. Mature security markets in the United States provide a large variety of potential investments that appear to be attractive alternatives to the Social Security trust fund's implied rate return of 2.3%. These returns have a zero variance, which still makes them a good choice when compared to more volatile alternatives in the event of full or partial privatization of Social Security contributions assuming assets are allocated according to mean variance efficiency analysis.     

Stock market development under globalization: Whither the gains from reforms?

Over the past decades, many countries have implemented significant reforms (including financial liberalization, privatization, and regulatory and supervisory improvements) to foster domestic capital market development. Despite these policies, the performance of capital markets in several countries has been disappointing. To understand the effects of reforms, we study the impact of six capital market reforms on domestic stock market development and internationalization. We find that reforms tend to be followed by increases in domestic market capitalization and trading. But reforms are also followed by an increase in the share of activity in international equity markets, with potential negative spillover effects.     

Do Privatization IPOs Outperform in the Long Run?

This paper investigates the long-run stock returns of privatization initial public offering (IPO) firms using a sample of 241 privatization IPOs from 42 countries during the period 1981-2003. We compare one-, three-, and five-year holding period returns of privatization IPOs to those of the domestic stock market indices and to size and size- and book-to-market equity ratio (BM)-matched firms from the same countries. Consistent with previous studies, we find that privatization IPOs significantly outperform their domestic stock markets in the long run. However, they show less consistent abnormal long-term stock performance relative to their size or size- and BM-matched benchmark firms.     

The real effect of partial privatization on corporate innovation: Evidence from China's split share structure reform

We examine the real effect of partial privatization on corporate innovation. To establish causality, we explore plausibly exogenous variation in the expectation of further partial privatization generated by China's split share structure reform, which mandatorily converts non-tradable shares into freely tradable shares and opens up the gate to the further privatization of state-owned enterprises. We find that partial privatization prospects have a positive effect on corporate innovation. A better alignment of the interests of government agents with those of private shareholders and improved stock price informativeness appear to be two plausible underlying mechanisms. Our paper sheds new light on the real effects of partial privatization.     

How Does Investor Sentiment Affect Stock Market Crises? Evidence from Panel Data

We test the impact of investor sentiment on a panel of international stock markets. Specifically, we examine the influence of investor sentiment on the probability of stock market crises. We find that investor sentiment increases the probability of occurrence of stock market crises within a one‐year horizon. The impact of investor sentiment on stock markets is more pronounced in countries that are culturally more prone to herd‐like behavior, overreaction and low institutional involvement.     

Share pledges,tone of earnings communication conferences,and market reaction: evidence from China

We investigate how share pledging affects firms’ disclosures and influences investors in Chinese stock market. The tone of firm disclosures when there are shares pledged by controlling shareholders is more positive than that of firms without them. Considering tone inflation motivation and ability simultaneously, we find share pledge risk has an inverted U‐shaped relation with tone. Investors react positively to tone in short‐run windows, and firms with controlling shareholders’ pledges have higher stock returns for earnings communication conferences. We identify an inverted U‐shaped link between margin distance of controlling shareholders and stock returns for earnings communication conferences.     

The Choice of Private Versus Public Capital Markets: Evidence from Privatizations

We examine the impact of political, institutional, and economic factors on the choice between selling a state‐owned enterprise in the public capital market through a share issue privatization (SIP) and selling it in the private capital market in an asset sale. SIPs are more likely in less developed capital markets, for more profitable state‐owned enterprises, and where there are more protections of minority shareholders. Asset sales are more likely when there is less state control of the economy and when the firm is smaller. Our results suggest the importance of privatization activities in developing the equity markets of privatizing countries.     

Cross‐sectional determinants of post‐IPO stock performance: evidence from China

This paper examines the cross‐sectional determinants of post‐IPO long‐term stock returns in China. We document that the aftermarket P/E ratio has the most robust negative association with post‐IPO stock returns. The negative relation indicates that the market corrects the aftermarket overvaluation of IPO firms in the long run. Underwriter reputation has a positive effect on post‐IPO stock returns, while board size has a negative impact, consistent with the views that reputable underwriters mitigate the information asymmetry in IPO pricing and over‐sized boards reduce the effectiveness of corporate governance. However, we find little evidence indicating that the equity ownership structure is significantly associated with post‐IPO stock returns.     

The Risk‐Return Relation in International Stock Markets

We investigate the risk‐return relation in international stock markets using realized variance constructed from MSCI (Morgan Stanley Capital International) daily stock price indices. In contrast with the capital asset pricing model, realized variance by itself provides negligible information about future excess stock market returns; however, we uncover a positive and significant risk‐return tradeoff in many countries after controlling for the (U.S.) consumption‐wealth ratio. U.S. realized variance is also significantly related to future international stock market returns; more importantly, it always subsumes the information content of its local counterparts. Our results indicate that stock market variance is an important determinant of the equity premium.     

The impact of mandatory IFRS reporting on institutional trading costs: Evidence from Australia

This study examines the impact of mandatory International Financial Reporting Standards (IFRS) on the market quality of the Australian Securities Exchange (ASX) 200 constituent stocks. Using traditional metrics that are consistent with prior literature (i.e., bid‐ask spreads), the first stage analysis confirms that stock liquidity has improved. However, when the analysis is extended to consider the trading costs incurred by market participants (i.e., execution shortfall), results suggest liquidity has not changed significantly. The paper utilizes rich unique datasets that contain detailed trade information, and findings are robust after controlling for trade difficulty and market conditions. In the era of High Frequency Trading (HFT) and occurrences of ‘fleeting’ liquidity, this paper provides some evidence that while IFRS may have enhanced ‘visible’ bid‐ask spreads, tangible liquidity for market participants, particularly global institutional investors, has not improved significantly.     

Limit Order Book and Commonality in Liquidity

We show that the liquidity provided by an individual stock's limit order book comoves significantly with the market aggregate limit order book liquidity. A closer look at the inside and outside liquidity provided by different parts of limit order book suggests that inside liquidity is mainly influenced by market volatility, while idiosyncratic volatility has a larger impact on outside liquidity. Hence, limit order book inside liquidity exhibits higher commonality than outside liquidity. We also show that the comovement between the stock‐level and market‐aggregate limit order book liquidity measures is related to the commonality in the overall stock market liquidity.
