Stock splits, trading continuity, and the cost of equity capital

We hypothesize that managers use stock splits to attract more uninformed trading so that market makers can provide liquidity services at lower costs, thereby increasing investors’ trading propensity and improving liquidity. We examine a large sample of stock splits and find that, consistent with our hypothesis, the incidence of no trading decreases and liquidity risk is lower following splits, implying a decline in latent trading costs and a reduced cost of equity capital. Further, split announcement returns are correlated with the improvements in both liquidity levels and liquidity risk. Our analysis suggests nontrivial economic benefits from liquidity improvements, with less liquid firms benefiting more from stock splits.     

Liquidity, redistribution, and the welfare cost of inflation

The long-run welfare costs of inflation are studied in a micro-founded model with trading frictions and costly liquidity management. By modelling the liquidity management decision, the model endogenizes the responses of velocity, output, the degree of market segmentation, and the distribution of money. Compared to the traditional estimates based on a representative agent model, the welfare costs of inflation are significantly smaller due to distributional effects of inflation. The welfare cost of increasing inflation from 0% to 10% is 0.62% of consumption for the US economy. Furthermore, the welfare cost is generally non-linear in the inflation rate.     

Real Earnings Management,Liquidity Risk and REITs SEO Dynamics

We analyze how REITs managers use real earnin gs management to address issues of liquidity risk and increased cost of capital they face during seasoned equity offerings. We show that REITs managers engage in real earnings management instead of accrual earnings management to attract more uninformed trading in order to provide the liquidity service at a lower cost during seasoned equity offerings. We find REITs with higher liquidity risk are more likely to manipulate earnings prior to equity offerings and uninformed trading is higher following real earnings management. Firms set the offer price at a smaller discount after engaging in real earnings management and stock returns decline in the long run. The findings are consistent with real option and liquidity risk explanations for equity offerings.     

The market liquidity of DIAMONDS,Q's,and their underlying stocks

We investigate the market liquidity effects of the introduction of index-tracking stocks for the Dow Jones Industrial Average (DIAMONDS) and the NASDAQ 100 index (Q's). Our main finding is liquidity of the underlying DJIA 30 index stocks improves after the introduction of the exchange-traded fund, largely because of a decline in the cost of informed trading. Further, we find the DIAMONDS has significantly lower liquidity costs over the first 50 days of trading as compared to the portfolio of its component stocks, again primarily because of lower adverse selection costs. Finally, we find weaker but qualitatively similar results for the Q's.     

Cross-listing and liquidity in emerging market stocks

In this study, we analyze liquidity costs for stocks and ADRs from the four main Latin American markets. The results indicate that international investors are exposed to different trading costs in Latin America, with market location and firm size as important determinants. In the local market, stocks that cross-list internationally do not always present a liquidity cost advantage relative to non-cross-listed stocks. When the ADR and the local stock markets are compared, large firms present lower trading costs in the home market. The opposite occurs for small firms.     

What Explains the Bid‐Ask Spread Decline after Nasdaq Reforms?

This paper examines whether the decrease in bid‐ask spreads on Nasdaq after the 1997 reforms is due to a decrease in market‐making costs and/or an increase in market competition for order flows. Unlike previous studies, we jointly examine how competition and trading costs affect bid‐ask spreads. In addition, we separate the effects of informed trading and liquidity costs on bid‐ask spreads. Informed trading cost is directly estimated for each Nasdaq stock using a Bayesian theoretic model. Empirical results show that market‐making costs and competition significantly affect bid‐ask spreads. The post‐reform decrease in bid‐ask spreads is largely due to both an increase in competition and a decrease in informed trading and liquidity costs on Nasdaq.     

Trade Disclosure,Information Learning and Securities Market Performance

In this paper we examine the effect of information disclosure on securities market performance when liquidity traders are able to acquire information about inside trading. We show that the bid-ask spread increases with the liquidity trader's learning efficiency, which is greater when trade information is disclosed. The bid-ask spread is always higher when trade information is not disclosed. However, the discrepancy between the bid-ask spreads with and without information disclosure narrows when the learning efficiency increases. We also show that the gains of the informed traders in a market without trade information disclosure are reduced in the presence of the liquidity trader's learning. Nevertheless, liquidity traders do not necessarily benefit from increased transparency. In particular, liquidity traders may face higher trading costs.     

Liquidity Externalities and Adverse Selection: Evidence from Trading after Hours

This paper examines liquidity externalities by analyzing trading costs after hours. There is less than 1/20 as many trades per unit time after hours as during the trading day. The reduced trading activity results in substantially higher trading costs: quoted and effective spreads are three to four times larger than during the trading day. The higher spreads reflect greater adverse selection and order persistence, but not higher dealer profits. Because liquidity provision remains competitive after hours, the greater adverse selection and higher trading costs provide a direct measure of the magnitude of the liquidity externalities generated during the trading day.     

UNLISTED TRADING PRIVILEGES,LIQUIDITY, AND STOCK RETURNS

In this study we examine the effect of dual trading through unlisted trading privileges (UTPs) on liquidity and stock returns. Stocks with UTPs trade in a different market structure than stocks listed and traded only on the AMEX and NYSE. Differences in market structure may affect stock returns through liquidity services provided by the competing markets. The sample comprises 852 AMEX and NYSE firms that began unlisted trading on the Philadelphia, Pacific, Midwest, or Cincinnati exchanges between 1984 and 1988. The results show significantly positive abnormal returns around the SEC's announcement of a regional exchange's filing for UTPs. The results also suggest that increased competition improves trading liquidity. Only stocks with low liquidity before UTPs announcements experience significantly improved liquidity and positive stock returns.     

Blocks, Liquidity, and Corporate Control

The paper develops a simple model of corporate ownership structure in which costs and benefits of ownership concentration are analyzed. The model compares the liquidity benefits obtained through dispersed corporate ownership with the benefits from efficient management control achieved by some degree of ownership concentration. The paper reexamines the free-rider problem in corporate control in the presence of liquidity trading, derives predictions for the trade and pricing of blocks, and provides criteria for the optimal choice of ownership structure.     

Effect of ownership,governance, and transparency on liquidity – Chilean evidence

Companies with relatively thin trading, a high concentration of insider ownership, and a privatized pension system characterize Chile’s Santiago Stock Exchange. Within this setting, we study the relationship between ownership concentration, corporate governance, and stock market liquidity. Our results suggest that board independence, corporate disclosure and outside monitoring by institutions help moderate the effects that insiders have on trading costs and liquidity. We also find that market makers with inventory reduce the informational component of trading costs. Finally, the trades of insiders provide price guidance to market makers, while traders employ a follow-the-insider strategy when transparency is low.     

Co‐managers,Information, and the Secondary Market Liquidity of Initial Public Offerings

We provide evidence that co‐managers improve initial public offering (IPO) liquidity through the “information” services they provide. Based on a sample of IPOs completed from January 1993 to December 2005, we find that a high number of co‐managers in the syndicate are associated with a lower spread, lower adverse selection costs, and a lower probability of informed trading. Moreover, increases in the offer price revision, in co‐managers’ underwriting rank, and in the number of analyst recommendations are all associated with the improvement in liquidity. This evidence is consistent with the hypotheses that co‐managers’ premarket and postmarket services mitigate information risk in the aftermarket.     

Transaction costs, trading volume, and the liquidity premium

In a market with one safe and one risky asset, an investor with a long horizon, constant investment opportunities and constant relative risk aversion trades with small proportional transaction costs. We derive explicit formulas for the optimal investment policy, its implied welfare, liquidity premium, and trading volume. At the first order, the liquidity premium equals the spread, times share turnover, times a universal constant. The results are robust to consumption and finite horizons. We exploit the equivalence of the transaction cost market to another frictionless market, with a shadow risky asset, in which investment opportunities are stochastic. The shadow price is also found explicitly.     

An analysis of depth behavior in an electronic, order-driven environment

The purpose of this study is to investigate inter-temporal and cross-sectional depth patterns in an electronic, order-driven environment. Although many exchanges operate in this environment, little is known about the liquidity dynamics induced by such trading mechanisms. The findings, based on over six million observations, reveal an inverted U-shaped pattern that mirrors the commonly reported U-shaped spread pattern. An important implication is that earlier spread results understate the strength of inter-temporal liquidity variations. Cross-sectional analysis, based on adverse selection-sorted portfolios, demonstrates that corporate depth is negatively related to information asymmetry. The adverse selection impact on liquidity and cost of capital is stronger than previously believed since information costs are realized through both spreads and depths.     

Trading costs, liquidity, and asset holdings

In this article I develop a model that accounts for interdependencebetween trading costs in various asset markets arising fromthe optimizing behavior of liquidity traders. The model suggeststhat noise trading is an important determinant of the liquidityof asset markets and provides a positive theory for diversifiedasset holdings by risk-neutral liquidity traders.     

Subsidizing Liquidity: The Impact of Make/Take Fees on Market Quality

Facing increased competition over the last decade, many stock exchanges changed their trading fees to maker‐taker pricing, an incentive scheme that rewards liquidity suppliers and charges liquidity demanders. Using a change in trading fees on the Toronto Stock Exchange, we study whether and why the breakdown of trading fees between liquidity demanders and suppliers matters. Posted quotes adjust after the change in fee composition, but the transaction costs for liquidity demanders remain unaffected once fees are taken into account. However, as posted bid‐ask spreads decline, traders (particularly retail) use aggressive orders more frequently, and adverse selection costs decrease.     

Measuring institutional trading costs and the implications for finance research: The case of tick size reductions

Using proprietary institutional trade data, we construct a price impact measure that represents the costs faced by institutional investors. We show that many widely used liquidity measures do not adequately capture institutional trading costs. We then find that institutional trading costs are not dramatically impacted by decimalization, casting doubt on the widely used identification strategy that employs decimalization as an exogenous shock to liquidity, particularly institutional liquidity. Indeed, we find that conclusions from prior research are significantly altered when we measure liquidity using institutional trading data.     

Liquidity and firm investment: Evidence for Latin America

This paper explores the relationship between firms' investment and stock market liquidity. Using a panel of Latin American firms, I find evidence that a higher trading volume and a higher industry-adjusted trading volume are associated with higher firm investment (PPE, Total Assets, and Inventory). This relationship is higher in episodes where the firm decides to issue shares, and it is also greater for firms with tighter financial constraints and better investment opportunities. This evidence is consistent with a mispricing channel, where firms issue and invest the proceeds to take advantage of low cost of capital, or with a cost channel, where liquidity is associated with lower issuance costs. Also, it is less related with an informational channel, where a liquid market helps a manager to take more efficient decisions, since this channel does not necessarily predict an increase in investment, but only more efficient investment.     

Equity trading by institutional investors: Evidence on order submission strategies

The trading volume channeled through off-market crossing networks is growing. Passive matching of orders outside the primary market lowers several components of execution costs compared to regular trading. On the other hand, the risk of non-execution imposes opportunity costs, and the inherent “free riding” on the price discovery process raises concerns that this eventually will lead to lower liquidity in the primary market. Using a detailed data set from a large investor in the US equity markets, we find evidence that competition from crossing networks is concentrated in the most liquid stocks in a sample of the largest companies in the US. Simulations of alternative trading strategies indicate that the investor’s strategy of initially trying to cross all stocks was cost effective: in spite of their high liquidity, the crossed stocks would have been unlikely to achieve at lower execution costs in the open market.     

Latency,liquidity and price discovery

The speed of trading is an important factor in modern security markets, although relatively little is known about the effect of speed on liquidity and price discovery, two important aspects of market quality. On April 23, 2007, Deutsche Boerse made an important upgrade to their trading system. With the 8.0 release of Xetra, system latency was reduced from 50 ms to 10 ms. Subsequently, both quoted and effective spreads decreased, which are mainly concentrated in small- and medium-sized stocks. This increase in liquidity is due to dramatically lower adverse selection costs that were only partially translated into higher liquidity. We interpret this as a decrease in the competition between liquidity suppliers who are able to increase their revenues by more than 90 million euros. The contribution of quotes to price discovery doubles to 90% post upgrade, indicating that prices are more efficient.
