It seems reasonable to expect systematic liquidity shocks to affect the optimal behavior of agents in financial markets. Indeed, fluctuations in various measures of liquidity are significantly correlated across common stocks(Chordia, Roll and Subrahmanyam (2000)). Thus, this paper empirically analyzes whether Spanish expected returns during the nineties are associated cross-sectionally to betas...

This paper develops a continuous-time model of the public and private provision of liquidity and its relation to unemployment. We extend the Mortensen-Pissarides model of the labor market by adding an over-the-counter (OTC) market where trades are collateralized with claims on …rms’pro…ts and public liabilities backed by taxes. As a result, the real interest rate is endogenous and depends on th...

We study the impact of public information on insider trading in the context of Kyle’s speculative market. The linear Nash equilibrium is characterized analytically. We find that public information is detrimental for the insider and beneficial for the liquidity traders. The insider puts a negative weight on the public information in formulating his optimal strategy. The equilibrium price becomes...

We show that the dispersion of private valuation reduces market liquidity and allocative e ciency of a dynamic OTC market. In this decentralized market, traders have time varying and heterogeneous private value over the asset and dealers act as competing mechanism designers. We characterize the optimal liquidity provision with endogenous valuation, outside options and type distributions. Depend...

This paper examines the interaction of idiosyncratic risk, liquidity and return across time in determining fund performance, as well as across investment style portfolios of European mutual funds. This study utilizes a unique data set including returns for equity mutual funds registered in six European countries. Overall, using monthly data, we find that both liquidity and idiosyncratic risk ar...

This paper studies portfolio choice and pricing in markets in which immediate trading may be impossible. It departs from the literature by removing restrictions on asset holdings, and finds that optimal positions depend significantly and naturally on liquidity: When expected future liquidity is high, agents take more extreme positions, given that they do not have to hold those positions for lon...

This paper provides an ontology-based set of Petri-nets for simulating the effect of business process changes on an organisation’s liquidity, and demonstrates that certain types of business process redesign can increase or reduce the amount of external funding that is required to prevent an organisation from defaulting on its debt. This debt defaulting may lead to proliferating liquidity constr...

The recent crisis was characterized by massive illiquidity. This paper reviews what we know and don't know about illiquidity and all its friends: market freezes, fire sales, contagion, and ultimately insolvencies and bailouts. It first explains why liquidity cannot easily be apprehended through a single statistic, and asks whether liquidity should be regulated given that a capital adequacy requ...

Most liquidity-providing operations of the European Central Bank (ECB) have been conducted through variable-rate tenders. However, fixed rates were first employed in the main refinancing operations (MROs) and are still used in other liquidity management operations. In October 2008, the ECB decided to carry MROs again at a fixed rate. In a simple threestage game in which banks can obtain liquidi...

This paper examines the dynamic behaviour of market liquidity on the Tunisian stock exchange (B.V.M.T.) using high frequency data from a reconstructed limit order book. The BVMT is an electronic pure order driven market that relies only on limit orders to supply liquidity, which may affect its viability and its resiliency. First, we apply a VAR model to stocks traded in continuous in order to e...
