Liquidity dynamics across public and private markets

In this paper we investigate cross-asset liquidity between equity markets and REITs and between REITs and private real estate markets. While many studies have investigated REIT liquidity, and there is an emerging interest in liquidity in the private real estate markets, there appears to be little knowledge of the dynamics of cross-market liquidity. We find lower levels of liquidity for REITs compared to a set of control firms matched on size and book-to-market ratios. Commonality in liquidity is also lower for REITs than the controls and the overall market. However, we do find an important difference in share turnover for REITs, which appears to have a higher level of commonality than found in other studies. We suggest that this may be due to the financial crisis. Additionally we find evidence of similar time-series variation in liquidity for public and private real estate markets. We also find significant directional causality for most liquidity proxies from the public to private real estate markets. Finally our results show that there is strong contemporaneous correlation between both public and private real estate market liquidity and the term spread and real investment and consumption spending. REIT liquidity measures based on intraday data also appear to contain important information not found in measures constructed from daily returns.     

Expectations and the asset-market approach to the exchange rate

This paper advances the following arguments concerning that portion of the literature characterized by deterministic models in which asset markets adjust quickly relative to the commodity market: (i) Overshooting of the exchange rate in response to exogenous shocks is not inherent. (ii) Perfect foresight and stability are incompatible. (iii) An alternative trade-balance approach is free of this incompatibility and also illustrates that two competing theories of the exchange rate are consistent. The analysis is general enough to include all interesting assumptions about expectations formation and therefore embraces many recent contributions as special cases.     

流动性过剩与流动性悖论

造成当前流动性过剩的一个重要原因是由于我国存在着一种"流动性悖论".而造成流动性悖论的原因又可以上溯到国内金融结构的体制性缺陷,具体包括银行体系、资本市场、人民币汇率制度和资本账户管制等四个方面的结构性问题.要根本上解决国际收支"双顺差"以及流动性悖论,长期看需要从经济与金融结构层面进行调整,近期则主要是汇率的调整,取消强制结汇制以及加强周边国家(地区)的政策协调.     

Sources of Liquidity and Liquidity Shortages

We develop a model of liquidity shortages that incorporates a general equilibrium feature of liquidity: when banks hold more liquidity, other agents in the economy hold less of it and will supply less in times of crisis. We show that the private holdings of liquidity at banks are inefficient, with the direction of the bias being determined by the characteristics of the suppliers of liquidity to banks. Minimum liquidity requirements for banks may reduce welfare; in such cases interest rate policies that stimulate the ex-post supply of liquidity can restore efficiency. Overall, our results show that optimal liquidity policies critically depend on a financial institution’s (marginal) source of liquidity and will hence differ across institutions of different types.     

商业银行经营中的流动性、流动性风险及其管理

一、流动性、流动性风险与银行挤兑 商业银行的流动性是指银行能够随时满足存款者的提现需求和借款者的正当贷款需求的能力.流动性是银行的生命线,也是整个金融体系及至整个经济体系对流动性需求的保证.盈利性和流动性是银行风险管理首先要解决的一对矛盾.如果银行持有大量的高流动性资产,当然可以减少流动性风险,但是同时也降低了银行的收益.     

Asset Liquidity and Stock Liquidity: International Evidence

This study examines the relationship between asset liquidity and stock liquidity across 47 countries. In support of the valuation uncertainty hypothesis, we find that firms with greater asset liquidity on average have higher stock liquidity. More importantly, our study shows that asset liquidity plays a more significant role in resolving valuation uncertainty in countries with poor information environment. For example, we find that the asset–stock liquidity relationship is stronger in countries with poor accounting standards. We further find evidence that after the adoption of IFRS, the improved accounting information environment results in a weaker asset–stock liquidity relation, but only in countries with a strong legal regime. Finally, our study shows that the positive asset–stock liquidity relationship may be attributed to transparency and/or liquidity reasons.     

流动性、银行间市场摩擦与借贷便利类货币政策工具

通过内生引入流动性短缺银行(拆入行)对流动性盈余银行(拆出行)的流动性需求机制,本文构建了一个包含银行间市场的DSGE模型,对借贷便利类货币政策工具的传导机制和传导效果进行了理论和实证研究。研究表明:(1)负向冲击会同时增加拆入行和拆出行对流动性的预防性需求,在经济形势不确定的情形下,拆出行不会很快恢复对拆入行的流动性供给,引起银行间市场流动性缺口放大和市场失灵。(2)由于仅依赖银行间市场自发回归稳态的过程太过缓慢,需要央行进行流动性干预。借贷便利类工具可以通过引导贷款市场定价和流动性效应这两个渠道来影响银行融资可得性,进而降低银行间市场流动性风险对宏观经济的负面影响。(3)借贷便利类货币政策工具的影响效果边际递减,央行可根据借贷便利操作的收益和成本,制定最佳的反应程度参数。     

Banks' Liquidity and the Cost of Liquidity to Corporations

We consider the liquidity shock banks experienced following the collapse of the asset‐backed commercial paper (ABCP) market in the fall of 2007 to investigate whether banks' liquidity conditions affect their ability to provide liquidity to corporations. We find that banks that borrowed more from the Federal Home Loan Bank system or the Federal Reserve's discount window following that liquidity shock passed a larger portion of their borrowing costs onto corporations seeking access to liquidity when compared to the precrisis period. This increase is larger among banks with a bigger exposure to the ABCP market, credit lines that pose more liquidity risk to banks, and borrowers that are likely dependent on the credit‐line provider. Our findings show that the crisis that affected the banking system had a negative effect not only on the price of credit to corporations, but also on the price corporations pay to guarantee access to liquidity.

Information and Liquidity

We study how recognizability affects assets’ acceptability, or liquidity. Some assets, like U.S. currency, are readily accepted because sellers can easily recognize their value, unlike stock certificates, bonds or foreign currency, say. This idea is common in monetary economics, but previous models deliver equilibria where less recognizable assets are always accepted with positive probability, never probability 0. This is inconvenient when prices are determined through bargaining, which is difficult with private information. We construct models where agents reject outright assets that they cannot recognize, at least for some parameters. Thus, information frictions generate liquidity differences without overly complicating the analysis.     

Liquidity and leverage

In a financial system in which balance sheets are continuously marked to market, asset price changes appear immediately as changes in net worth, and eliciting responses from financial intermediaries who adjust the size of their balance sheets. We document evidence that marked-to-market leverage is strongly procyclical. Such behavior has aggregate consequences. Changes in dealer repos – the primary margin of adjustment for the aggregate balance sheets of intermediaries – forecast changes in financial market risk as measured by the innovations in the Chicago Board Options Exchange Volatility Index VIX index. Aggregate liquidity can be seen as the rate of change of the aggregate balance sheet of the financial intermediaries.     

Trader Leverage and Liquidity

Does trader leverage drive equity market liquidity? We use the unique features of the margin trading system in India to identify a causal relationship between traders’ ability to borrow and a stock's market liquidity. To quantify the impact of trader leverage, we employ a regression discontinuity design that exploits threshold rules that determine a stock's margin trading eligibility. We find that liquidity is higher when stocks become eligible for margin trading and that this liquidity enhancement is driven by margin traders’ contrarian strategies. Consistent with downward liquidity spirals due to deleveraging, we also find that this effect reverses during crises.     

流动性的度量及其与资产价格的关系

本文将流动性划分为货币流动性、银行系统流动性和市场流动性三个层次,总结了相应的可操作的度量方法,并通过中国数据进行了度量,从一个侧面论证了货币流动性是市场流动性的基础,以及市场流动性高时资产价格一般也较高的观点。基于货币流动性的基础性地位,本文进一步考察了货币流动性与资产价格的关系,发现超额货币流动性不仅影响股票的名义回报,还影响股票的真实回报;货币流动性在长期内受到股票真实回报的反作用,但这种作用可能是相对微小的。     

流动性导流——中国货币需求及现阶段流动性过剩问题研究

近年来,流动性过剩成为了我国宏观经济的要害性问题.所谓"流动性导流",就是将目前过剩的流动性通过若干可能的渠道疏导到实体经济之外,使之基本不对实体经济产生负面影响.我国流动性过剩是由外向型经济结构引起的外汇过多流人造成的,在经济结构短期内难以根本改变且人民币升值预期难以根本逆转的情况下,只能从疏导过多流动性的角度来寻找防治通胀之道.具体的疏导渠道包括将一部分流动性导向境外和在境内扩大虚拟经济以吸收一部分流动性.后者是解决当前通胀压力和股市扩容压力的一箭双雕之策,也是本文的新观点所在.     

Liquidity and market efficiency

Short-horizon return predictability from order flows is an inverse indicator of market efficiency. We find that such predictability is diminished when bid-ask spreads are narrower, and has declined over time with the minimum tick size. Variance ratio tests suggest that prices were closer to random walk benchmarks in the more liquid decimal regime than in other ones. These findings indicate that liquidity stimulates arbitrage activity, which, in turn, enhances market efficiency. Further, as the tick size decreased, open-close/close-open return variance ratios increased, while return autocorrelations decreased. This suggests an increased incorporation of private information into prices during more liquid regimes.     

金融双语

过剩与不足，或说供大于求与求大于供，都是经济中的非均衡状态。这里的供求对应于意愿的交换数量，即在市场均衡时交易者在不受数量约束的情况下，根据效用最大化原则在现行价格下进行交易的名义供求量。当意愿的交换数量与实际的交易数量不同时，就出现了非均衡。而非均衡也可以是一种均衡，又称非瓦尔拉斯均衡。非瓦尔拉斯均衡是指在一定约束条件下，构成某一经济系统的相互作用的变量经过调整后，该系统不再存在继续变动的趋势，经济处于稳定状态。如果市场是充分有效的，则实际交易需求就取决于意愿供求的短边，即遵循“短边原则”。如果市场上存在摩擦，则实际交易量就会小于意愿供求的任何一方。由于垄断等因素引起的价格刚性、配额问题以及调整成本等的存在，以及由于计划经济中的预算软约束等因素干扰了利润最大化的决策，破坏了瓦尔拉斯均衡的实现前提，使非瓦尔拉斯均衡广泛存在。对于非均衡经济，理性经济人的行为不仅取决于价格信号，还要综合考虑数量信号。     

Liquidity uncertainty and intermediation

The paper performs a welfare comparison between demand deposit and equity contracts in the presence of intrinsic aggregate uncertainty. In this framework, the welfare dominance of deposit contracts emerges under corner preferences. It is shown that aggregate uncertainty creates high price volatility of ex-dividend equity claims traded in a secondary market and the resulting consumption allocations offer less risk-sharing opportunities to risk-averse consumers than tailor-made deposit contracts. The contingency of early payoffs on depositors’ withdrawal order reinforces the welfare performance of deposit contracts, whereas costly liquidation of productive long-term investments deteriorates their welfare performance relative to equity contracts.     

Liquidity and Credit Risk

We develop a structural bond valuation model to simultaneously capture liquidity and credit risk. Our model implies that renegotiation in financial distress is influenced by the illiquidity of the market for distressed debt. As default becomes more likely, the components of bond yield spreads attributable to illiquidity increase. When we consider finite maturity debt, we find decreasing and convex term structures of liquidity spreads. Using bond price data spanning 15 years, we find evidence of a positive correlation between the illiquidity and default components of yield spreads as well as support for downward‐sloping term structures of liquidity spreads.     

External Financing and Liquidity

We explain the observed negative relation between market value of firms and their fund raising activities. Ours is not a signalling model. The firm's objective is to maximize the present value of its income. Considerations of cash availability (liquidity) and unfolding of uncertainty drive our model. Income from operations is an important source of liquidity. Low earnings are associated with low liquidity. Whether earnings are low or not is known to some extent in advance of the realization itself. External financing is pursued in anticipation of the earnings' realization in order to maintain a desired level of liquidity. Therefore, anticipated low earnings are associated with a high level of external financing. Of course, an anticipation of low earnings is also accompanied by a decrease in the firm's value. The empiricist who looks at time series of a firm's value and of its dividend/external financing announcements would then record positive correlation between value and cash distributions and negative correlation between value and external financing.
