Money and liquidity in financial markets

We argue that there is a connection between the interbank market for liquidity and the broader financial markets, which has its basis in demand for liquidity by banks. Tightness in the market for liquidity leads banks to engage in what we term “liquidity pull-back,” which involves selling financial assets either by banks directly or by levered investors. Empirical tests on the stock market are supportive. Tighter interbank markets are associated with relatively more volume in more liquid stocks; selling pressure, especially in more liquid stocks; and transitory negative returns. We control for market-wide uncertainty and in the process also contribute to the literature on portfolio rebalancing. Our general point is that money matters in financial markets.     

Monetary policy and bank lending in the Euro area: Is there a stock market channel or an interest rate channel?

In this paper I compare a traditional demand oriented model of bank lending with its focus on short-term interest rates in the money market, to a non-traditional capital budgeting model of bank lending based on movements in share valuations for the Euro area. Using non-nested hypothesis tests, omitted variables tests, and Granger Causality tests, I reject the traditional demand oriented model of bank lending and fail to reject the capital budgeting model of bank lending for Monetary Financial Institutions (MFI's) in the Euro area. Even though Europe is a bank-based financial system, it appears the stock market plays a key role in the lending decisions and allocation of resources in Europe. One possible policy implication of this research is that the central bank should try and stabilize stock prices in order to achieve their goal of stabilizing bank lending and the economy.     

Does bank lending affect output? Evidence from the U.S. states

This paper uses a panel of state-level data to test whether changes in bank loan supply affect output. Since the U.S. states are small open economies with fixed exchange rates, state-specific shocks to money demand are automatically accommodated, leading to changes in lending if banks rely on deposits as a source of funding. Using these shocks as an instrumental variable, I find that shocks to money demand have large and statistically significant effects on the supply of bank loans, but loans have small, often negative and statistically insignificant effects on output.     

Revenue maximizing inflation

A classic monetary policy result is that revenue maximization entails setting the inflation tax rate equal to the inverse of the interest semi-elasticity of the demand for money. The standard approach underlying “Cagan's rule” is partial equilibrium in nature, treating money demand as being given from outside the model and abstracting from the real effects of inflation. This paper reconsiders the question of the revenue maximizing inflation rate in a general equilibrium framework with a labor-leisure choice, where money is held because it reduces transactions costs. In this framework, the revenue maximizing inflation tax rate is lower than that implied by Cagan's rule.     

Financial Innovations,Money Demand,and the Welfare Cost of Inflation

In the 1990s, the empirical relationship between money demand and interest rates began to fall apart. We analyze to what extent financial innovations can explain this breakdown. For this purpose, we construct a microfounded monetary model with a money market that provides insurance against liquidity shocks by offering short‐term loans and by paying interest on money market deposits. We calibrate the model to U.S. data and find that the introduction of the sweep technology at the beginning of the 1990s, which improved access to money markets, can explain the behavior of money demand very well. Furthermore, by allowing a more efficient allocation of money, the welfare cost of inflation decreased substantially.     

“Black Swans” before the “Black Swan” evidence from international LIBOR–OIS spreads

The LIBOR–OIS spread is a closely monitored indicator of the financial health of economy. Previous research has used this spread to identify and anticipate abrupt changes in financial markets. Taylor and Williams (2009) refer to the drastic increase in the US LIBOR–OIS spread on August 7th, 2007 as a “Black Swan” in the money market. In this paper, rather than rely on visual observations of “Black Swans” we estimate them using Bai and Perron’s (1998) procedure. We estimate structural breaks, Granger causality tests, and innovation accounting in international LIBOR–OIS spreads and a CDS index to better understand their dynamics during the recent crisis. Our results reveal that “Black Swans” appeared in smaller economies prior to that in large ones during the financial crisis. In addition, we find that only shocks to the US LIBOR–OIS spread has any statistically significant effects after 30 days.     

Financial innovation,new assets,and the behavior of money demand

Two fundamental changes in US banking regulations have affected the behavior of money demand (M1). The first authorized checkable deposit accounts paying explicit interest rates. The second allowed these rates to be market determined. The theoretical literature does not directly address the impact of these events, suggesting that they are primarily an empirical issue. However, the empirical literature has yet to agree on the impact of financial innovation on money demand; for example, several studies report an increase in the elasticity of money demand, several others report a decline. This paper uses a Lancaster-type choice model to analyze formally the expected impact of these two changes on the demand for money. The model derives specific conditions under which (i) the demand for money increases as new assets are introduced and (ii) the impact of either the introduction of new assets or the elimination of interest rate restrictions on the elasticity of money demand.     

Money Velocity in an Endogenous Growth Business Cycle with Credit Shocks

The paper sets the neoclassical monetary business cycle model within endogenous growth, adds exchange credit shocks, and finds that money and credit shocks explain much of the velocity variations. The role of the shocks varies across subperiods in an intuitive fashion. Endogenous growth is key to the construction of the money and credit shocks because these have similar effects on velocity, but opposite effects upon growth. The model matches the data's average velocity and simulates well velocity volatility. Its Cagan-like money demand means that money and credit shocks cause greater velocity variation, the higher is the nominal interest rate.     

Money demand heterogeneity and the great moderation

A forward-looking model of the demand for money based on heterogeneous and sluggish-portfolio adjustment can simultaneously account for the low short-run and high long-run semi-elasticities reported in the literature. The parameter estimates from the model for the short-run and long-run interest semi-elasticities are 1.04 and 13.16, respectively. A simulated version of the model suggests that the Great Moderation can be partially attributed to financial innovations in the late 1970s. When moving toward a more flexible portfolio, the model can account for almost one-third of the observed decline in the volatilities of output, consumption, and investment.     

Fair value accounting,fragile bank balance sheets and crisis: A model

A topic of recent interest in accounting research has been the investigation of the role of fair value accounting (FVA) in the global financial crisis. This research focused on finding a link during the crisis time-period and often states that “accounting is only a messenger”. The model presented in this paper emphasises finding the link before the crisis and “accounting as money.” Use is made of an accounting model of the economy due to the inability of standard models of monetary transmission to incorporate global financial crisis characteristics such as feedback effects, systemic risk and the centrality of the financial sector in the crisis. The model shows FVA in banks to be an accelerator that amplifies the financial cycle upswing. Feedback effects noted in the model include changes in the demand for financial instruments and changes in demand in the real economy. Minsky-like, crisis is shown to be endogenous to the model, working through the fragility of balance sheets in the real sector as well as in the financial sector. Bank balance sheet fragility is caused by bad capital driving out good capital, banks reaching for yield and the inversion of the yield curve. The model shows that the practice of not meeting rising credit demand with increasing credit supply is an essential control mechanism in the financial cycle.     

结构扭曲与中国货币之谜——基于转型经济金融抑制的视角

转型经济中金融抑制的表现是对利率和汇率的管制。本文认为利率和汇率管制降低了持币成本,直接增加了货币需求,其导致的投资和对外经济结构扭曲则间接地增加了货币需求。中国的高货币速增长就是为了满足超额货币需求所致。我们利用中国1994年第1季度到2010年第2季度数据估计了M1和M2的真实余额需求的协整和误差修正方程。实证结果基本支持本文的金融抑制假说。在一个保守估计下,我们认为金融的抑制至少导致了现有的M2/GDP偏高30%。     

Banks, private money, and government regulation

We study competition between inside and outside money in economies with trading frictions and financial intermediation. Claims on banks circulate if the redemption rate is low. When the quantity of fiat money is scarce, coexistence of inside and outside money dominates equilibria with a unique medium of exchange. If outside money is ample, banks choose to redeem claims in outside money, which increases welfare. Under binding reserve requirements, tightening monetary policy leads to credit rationing. Our results support recent trends toward lower reserve requirements. However, we also identify situations where restrictions on note issue are beneficial.     

Short-run money demand

The conventional wisdom holds that the short-run demand for money is unstable. This paper challenges the conventional view by finding a stable demand for M1 in U.S. data from 1959 through 1993. The approach follows previous work in interpreting long-run money demand as a cointegrating relation, and it uses Goldfeld's partial-adjustment model to interpret short-run dynamics. The key innovation is the choice of the interest rate in the money demand function. Most previous work uses a short-term market rate, but this paper uses the average return on “near monies”—the savings accounts and money market mutual funds that are close substitutes for M1. This choice helps rationalize the behavior of money demand; in particular, the increase in the volatility of velocity after 1980 is explained by increased volatility in the returns on near monies.     

Money as stock

The fiscal theory determines the price level from the value of nominal government debt as a claim to government primary surpluses, just as private stock is valued as a claim to corporate profits. Valuation equations are not constraints, so this theory does not mistreat the government's intertemporal budget constraint. I anchor the analysis in a simple cash in advance model. When money demand falls to zero, I show that the price level can still be determined by the government debt valuation equation.

Exchange Rates and Fundamentals: A General Equilibrium Exploration

Engel and West (2005) show that the observed near random‐walk behavior of nominal exchange rates is an equilibrium outcome of a partial equilibrium asset approach when economic fundamentals follow exogenous first‐order integrated processes and the discount factor approaches one. In this paper, I argue that the unit market discount factor creates a theoretical trade‐off within a two‐country general equilibrium model. The unit discount factor generates near random‐walk nominal exchange rates, but it counterfactually implies perfect consumption risk sharing and flat money demand. Bayesian posterior simulation exercises, based on post‐Bretton Woods data from Canada and the United States, reveal difficulties in reconciling the equilibrium random‐walk proposition within the canonical model; in particular, the market discount factor is identified as being much smaller than one. A relative money demand shock is identified as the main driver of nominal exchange rates.     

Money and credit in liquidity provision

This paper studies the liquidity provision in a model where the roles of money are challenged by other financial instruments. Alternative to money, credit can be used as means of payment and rate dominating assets are available to serve as stores of value. Two features are found to be crucial in rendering money valuable in this environment: information asymmetry in credit trading relationship and uncertainty in individuals' liquidity demand. In general, the model economy can display a payment mechanism of money-only, credit-only, or mixed-use of money and credit in transactions, depending on the severity of the information asymmetry. The optimal quantity of money in our paper is shown to contrast those in other monetary models.     

Financial progress and the stability of long-run money demand: Implications for the conduct of monetary policy in emerging economies

This paper examines whether recent financial changes in three emerging market economies in the Gulf region (Bahrain, the UAE, and Qatar) have distorted the character and the stability of their underlying long-run money demand relations. Money demand instability prompts concerns about the appropriateness of targeting monetary aggregates and could weaken the presumed link between monetary policy and its ultimate objectives. Our results suggest that the quick pace of financial changes in the three emerging market economies did not cause undue shifts in their equilibrium money demand relations. Further evidence from direct tests of cointegration stability indicates the superiority of targeting M1 in the UAE and M2 for Qatar. In Bahrain, both M1 and M2 prove equally appropriate to guide monetary policy. Thus, despite the wave of financial developments that have recently swept the three Gulf economies, the evidence suggests that monetary authorities in these countries should maintain a close watch on monetary growth as a principal policy guide.     

经济开放与货币需求:国际金融风险及持币成本的测度

在中国开放经济体制下的基准货币需求模型中,本文将源于国际金融市场的持币成本设为遗漏潜变量,并构建特定的国际金融综合指数(CIFI)作为该潜变量的测度。借鉴机器学习与测度理论,本文利用对数误差修正模型提出了分步降维的CIFI构造算法,构造了长期CIFI和短期CIFI。结果表明,CIFI构造中的无监督降维步骤有助于减少高维金融数据中的冗余信息。实证分析发现,国际机会成本对中国货币需求具有规律性的前导影响,而在2007至2008年国际金融危机期间,央行的应急措施对长期CIFI所代表的非均衡冲击起到明显的阻截效果,对短期CIFI的影响基本是持续不变的。通过综合指数构造与宏观货币需求模型的算法连接,可以利用CIFI的构成结构从前导时间与影响强度两方面追踪冲击货币需求的国际金融风险的具体来源,这为宏观决策者监测国际金融市场提供了颇有规律的信息。在方法论上,本研究为如何利用模型监测国际金融市场影响宏观经济开辟了一条新路。
