Money,Asset Prices,and the Liquidity Premium

This paper examines the effect of monetary policy on the market value of the liquidity services that financial assets provide, known as the liquidity premium. The theory predicts that money supply and nominal interest rates have positive effects on the liquidity premium, but asset supply has a negative effect. The empirical analysis with U.S. data confirms the theoretical predictions. The theory also proposes that the liquidity properties of assets can cause negative nominal yields when the money holding cost is low and liquid assets are scarce. The suggestive empirical findings in Switzerland to support this theoretical result are presented.     

Financial market participation and the apparent instability of money demand

This paper uses multi-period cross-sectional data on financial assets holdings to shed light on the postwar stability of money demand in the United States. I first present a new measure of the evolution of financial market participation, by relating participation to the extensive margins of money demand, and quantify the influence of wealth on participation decisions. I then relate the increase in participation to the period of “missing money” and to the subsequent higher interest rate elasticity of monetary aggregates. The paper indicates that time-series estimations of money demand relationships are inherently flawed and tend to inappropriately suggest instability.     

Monetary disequilibria and the euro/dollar exchange rate

Although stable money demand functions are crucial for the monetary model of the exchange rate, empirical research on exchange rates and money demand is more or less disconnected. This paper tries to fill the gap for the euro/dollar exchange rate. We investigate whether monetary disequilibria provided by the empirical literature on US and European money demand functions contain useful information about exchange rate movements. Our results suggest that the empirical performance of the monetary exchange rate model improves when insights from the money demand literature are explicitly taken into account.     

Asset Prices,Liquidity, and Monetary Policy in an Exchange Economy

I formulate a model in which money coexists with equity shares on a risky aggregate endowment. Agents can use equity as a means of payment, so shocks to equity prices translate into aggregate liquidity shocks that disrupt the mechanism of exchange. I characterize a family of optimal monetary policies and find that the resulting equity prices are independent of monetary considerations. I also study a perturbation of the family of optimal policies that targets a positive constant nominal interest rate and find that in this case the real equity return includes a liquidity return that depends on monetary considerations.     

Implications of bank ownership for the credit channel of monetary policy transmission: Evidence from India

Using bank-level data from India, we examine the impact of ownership on the reaction of banks to monetary policy, and also test whether the reaction of different types of banks to monetary policy changes is different in easy and tight policy regimes. Our results suggest that there are considerable differences in the reactions of different types of banks to monetary policy initiatives of the central bank, and that the bank lending channel of monetary policy is likely to be much more effective in a tight money period than in an easy money period. We also find differences in impact of monetary policy changes on less risky short-term and more risky medium-term lending. We discuss the policy implications of the findings.     

Deposit rate ceilings and monetary transmission in the US

Establishing the existence and nature of changes in the conduct and transmission of monetary policy is key in understanding the remarkable macroeconomic performance of the US since the mid-1980s. This paper presents evidence on a phenomenon of disintermediation occurring during the major recessions in the 1960s and 1970s, but absent ever since, and shows that disintermediation is closely linked to the existence of deposit rate ceilings under regulation Q. In a monetary DSGE model that incorporates deposit rate ceilings as occasionally binding constraints, the regulation alters the behavior of money aggregates and exacerbates the drop in economic activity following a monetary tightening. The results of a threshold VAR lend support to the main theoretical predictions of the model.     

Money Creation: Tax or Public Liquidity?

I revisit the example of non‐neutral anticipated monetary expansions used in Lucas (1995) Nobel Prize Lecture, within a broader definition of monetary policy tools, such as paying a nominal return on money or using open market operations, to show that money expansions increase output by reallocating consumption across heterogenous individuals and time periods. This result survives with noninterest‐bearing cash when the latter does not generate relevant distortions.     

The Discounted Economic Stock of Money with VAR Forecasting

We measure the economic capital stock of money implied by the Divisia monetary aggregate service flow, in a manner consistent with asset pricing theory. Based on Barnett’s (Monetary policy on the 75th anniversary of the Federal Reserve System, pp. 232–244, Kluwer, Boston, 1991) definition of the economic stock of money, we estimate the expected discounted flow of expenditure on the services of monetary assets, where expenditure on monetary services is evaluated at the user costs of the monetary components. We use forecasts based on martingale expectations, asymmetric vector autoregressive expectations, and the Bayesian vector autoregressive expectations. We find the resulting capital-stock index to be surprisingly robust to the modeling of expectations.     

Does Money Matter in Shaping Domestic Business Cycles? An International Investigation

We study the contribution of money to business‐cycle fluctuations in the United States, the United Kingdom, Japan, and the euro area using a small‐scale structural monetary business cycle model. Constrained likelihood‐based estimates of the parameters are provided and time instabilities analyzed. Real balances are statistically important for output and inflation fluctuations. Their contribution changes over time. Models giving money no role provide a distorted representation of the sources of cyclical fluctuations, of the transmission of shocks, and of the events of the last 40 years.

Optimal Monetary Policy in a Model of Money and Credit

We investigate the extent to which monetary policy can enhance the functioning of the private credit system. Specifically, we characterize the optimal return on money in the presence of credit arrangements. There is a dual role for credit: it allows buyers to trade without fiat money and also permits them to borrow against future income. However, not all traders have access to credit. As a result, there is a social role for fiat money because it allows agents to self‐insure against the risk of not being able to use credit in some transactions. We consider a (nonlinear) monetary mechanism that is designed to enhance the credit system. An active monetary policy is sufficient for relaxing credit constraints. Finally, we characterize the optimal monetary policy and show that it necessarily entails a positive inflation rate.     

Private Money and Banking Regulation

We show that a competitive banking system is inconsistent with an optimum quantity of private money. Because bankers cannot commit to their promises and the composition of their assets is not publicly observable, a positive franchise value is required to induce the full convertibility of bank liabilities. Under perfect competition, a positive franchise value can be obtained only if the return on bank liabilities is sufficiently low, which imposes a cost on those who hold these liabilities for transaction purposes. If the banking system is monopolistic, then an efficient allocation is incentive feasible. In this case, the members of the banking system obtain a higher return on assets, making it feasible to pay a sufficiently high return on bank liabilities. Finally, we argue that the regulation of the banking system is required to obtain efficiency.     

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.     

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.     

Price‐Level Targeting and Stabilization Policy

We construct a dynamic stochastic general equilibrium model to study optimal monetary stabilization policy. Prices are fully flexible and money is essential for trade. Our main result is that if the central bank pursues a price‐level target, it can control inflation expectations and improve welfare by stabilizing short‐run shocks to the economy. The optimal policy involves smoothing nominal interest rates that effectively smooths consumption across states.     

确定情形下的货币、利率与内生经济增长

通过对消费和资本投入施加预付现金约束,在内生经济增长框架（AK模型）下建立了一个封闭的货币经济体,并构建了以利率为核心的分析框架。研究表明,在确定情形下,利率的改变会影响代理人的消费与投资,并进而对价格和经济总体的消费与投资产生影响,货币当局可以通过利率以间接控制货币供给;当货币供给变化时,经济总体的消费与投资等变量也会发生变化,货币不是中性的;通过比较最优利率政策与Friedman法则,发现两者惟一的区别仅在于最初期利率的不同。     

Sticky Price Models,Durable Goods,and Real Wage Rigidities

The standard two‐sector New Keynesian model with durable goods is at odds with conventional wisdom and vector autoregression (VAR) evidence: Following a monetary shock, the model generates (i) either negative or no comovement across sectoral outputs and (ii) aggregate neutrality of money when durable goods' prices are flexible. We reconcile theory with evidence by incorporating real wage rigidities into the standard model: As long as durable goods' prices are more flexible than nondurable goods' prices, we obtain positive sectoral comovement and, thus, aggregate nonneutrality of money.     

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.     

Monetary Policy and Asset Prices: A Mechanism Design Approach

We investigate the effects of monetary policy on asset prices in economies where assets are traded periodically in bilateral meetings. The trading mechanism is designed to maximize social welfare taking as given the frictions in the environment and monetary policy. We show that asset price “bubbles” emerge in a constrained‐efficient monetary equilibrium only if liquidity is abundant and the first‐best allocation is implementable. In contrast, if liquidity is scarce, assets are priced at their fundamental value in any constrained‐efficient monetary equilibrium, in which case an increase in inflation has no effect on asset prices, but it reduces output and welfare.     

Real Balance Effects,Timing, and Equilibrium Determination

By assuming that money balances at the beginning instead of at the end of the period provide transaction services, standard results on nominal and real determinacy in monetary models are overturned. The key is that predetermined real money balances can be a state variable. Whereas the determination of the absolute price level typically depends on fiscal policy under an exogenous interest setting, nominal determinacy is now achieved even when fiscal policy is Ricardian. Also, in contrast to the Taylor principle, the interest rate policy should respond passively to changes in inflation, thus ensuring nonoscillatory and locally stable equilibrium sequences.
