Estimating the demand for money in Canada: Does including an own rate of return matter?

Traditional studies estimating the long-run demand for real money in Canada assume that narrow money, or M1, bears zero interest. However if implicit interest has been paid, such interest should be taken into account in determining the opportunity cost of holding money. Using quarterly data over the period 1961:1–2000:3 we construct and employ a competitive own rate of return variable. Over 1961:1–1982:1, the conventional money demand model which omits an own rate of return performs well. Over the period 1982:2–2000:3, where the degree of competition in the banking industry increased, the conventional money demand model does not perform well, whereas inclusion of the own rate of return yields correct parameter estimates.     

The dynamic relationship between stock,bond and foreign exchange markets

This paper investigates whether the deviation of a currency from its fundamentally determined rate of return affects the relationship between interest rates and stock market yields. A time-varying transition probability, the Markov-switching vector autoregressive (MS-VAR) model, is utilized for this purpose. Wald and likelihood ratio tests are computed and used as model adequacy measures. In order to analyze the link between the variables, impulse–response functions are employed. A sticky price exchange rate model is used to show the fundamentally determined rate of return of currencies. States are defined as either overvalued or undervalued, depending on the position of the observed exchange rate compared to its fundamentally determined rate. The model is applied to four major currencies: the Australian Dollar, the Canadian Dollar, the Japanese Yen, and the British Pound. Transition between the states is linked to the risk-adjusted excess return (the Sharpe ratio) of the debt and equity markets of the respective currencies in order to understand whether over- and undervaluation is connected to the returns in these markets. The results provide evidence that the relationship between economic fundamentals and nominal exchange rates are subject to change depending on the over- or undervaluation of the currencies relative to their fundamentally determined rate of return. An extension of this result shows that the Sharpe ratios of debt and equity investments in the currencies influence the evolution of the transitional dynamics of the exchange rates’ deviation from their fundamental values.     

Expectancy balance model for cash flow

Economic agents try to find out the composition of different forms of assets, and the amount of each, that maximizes total wealth. The money demanded by firms is a function of the benefits and costs of holding it considering other forms of assets. The money held in cash can be remunerated by some earning asset. Even when the money is invested in bank funds or bonds, the interest rate is usually lower than the return that the firm’s business may yield. When the firm keeps idle money in cash, the firm renounces to part of its profitability, incurring in the opportunity cost of not investing in alternatives, named Holding Cost. If the firm gives preference to other assets over cash, the balance level may be insufficient for its disbursement needs. The Shortage Cost is the price of obtaining money by other means. The Expectancy Balance Model (EBM) proposed minimizes the Total Cost (combined Holding and Shortage Costs) of maintaining and transforming money from or into other forms of assets. The EBM is an instrument of cash flow decision that deals with the demand for money by firms employing the maximizing utility of total wealth (set of assets) rule.     

The impact of systemic and illiquidity risk on financing with risky collateral

Repurchase agreements (repos) are one of the most important sources of funding liquidity for many financial investors and intermediaries. In a repo, some assets are given by a borrower as collateral in exchange of funding. The capital given to the borrower is the market value of the collateral, reduced by an amount termed as haircut (or margin). The haircut protects the capital lender from loss of value of the collateral contingent on the borrower׳s default. For this reason, the haircut is typically calculated with a simple Value at Risk estimation of the collateral for the purpose of preventing the risk associated to volatility. However, other risk factors should be included in the haircut and a severe undervaluation of them could result in a significant loss of value of the collateral if the borrower defaults. In this paper we present a stylized model of the financial system, which allows us to compute the haircut incorporating the liquidity risk of the collateral and, most important, possible systemic effects. These are mainly due to the similarity of bank portfolios, excessive leverage of financial institutions, and illiquidity of assets. The model is analytically solvable under some simplifying assumptions and robust to the relaxation of these assumptions, as shown through Monte Carlo simulations. We also show which are the most critical model parameters for the determination of haircuts.     

Empirical Modelling of Money Demand in Periods of Structural Change: The Case of Greece*

This paper examines the behaviour of the demand for money in Greece during 1976Q1 to 2000Q4, a period that witnessed many of the influences that cause money‐demand instability. Two empirical methodologies, vector error correction (VEC) modelling and second‐generation random coefficient (RC) modelling, are used to estimate the demand for money. The coefficients of both the VEC and RC procedures support the hypothesis that the demand for money becomes more responsive to both the own rate of return on money balances and the opportunity cost of holding money because of financial deregulation. In general, both procedures also support the hypothesis that the income elasticity of money demand declines over time as a result of technological improvements in the payments system and the development of money substitutes, which lead to economies of scale in holding money.     

Quantitative easing and the loan to collateral value ratio

We study optimal monetary policy in a New Keynesian model at the zero bound interest rate where households use cash alongside house equity borrowing to conduct transactions. The amount of borrowing is limited by a collateral constraint. When either the loan to value ratio declines or house prices fall, we observe a decrease in the money multiplier. We argue that the central bank should respond to the fall in the money multiplier and therefore to the reduction in house prices or the loan to collateral value ratio. We also find that optimal monetary policy generates a large and persistent fall in the money multiplier in response to the drop in the loan to collateral value ratio.     

The timing of residential land development: A general equilibrium approach

A formal model of the development process is constructed in order to arrive at a better understanding of the land development process, the change in land prices over time, and the effects of public policy on these variables. The relationship between the rate of interest and the rate of price appreciation on land is shown to depend upon development costs, agricultural opportunity costs, market structure, and the level of Ricardian rents on land. The effects of a land tax and a capital gains tax on the rate of development are also analyzed.

COLLATERAL AND CREDIT RATIONING: A REVIEW OF RECENT EMPIRICAL STUDIES AS A GUIDE FOR FUTURE RESEARCH

Abstract.  The relationship between firms and banks often suffers from informational opacity that may result in credit rationing. In theory, providing collateral to the bank can have a mitigating effect on these informational asymmetries and thus solve the credit-rationing problem. Even though collateral is already a widespread debt contract feature, recent trends predict that, in the future, collateral will become even more important for informationally opaque firms. The aim of this paper is twofold. First, we provide a review of the recently growing empirical research on collateral as a remedy for credit rationing. Second, we would like to pinpoint gaps and limitations in current empirical research. Most studies contend with a flawed research design by not distinguishing between business and personal collateral and excluding other information opaqueness reducing tools such as the strength of the relationship between borrower and lender, loan maturity and covenants. We also discuss the limitations of using a single equation estimation method and the usefulness of incorporating interaction effects into the estimation models. Finally, we provide suggestions for fruitful research avenues that would fill these gaps and enrich the empirical knowledge in this research domain.     

Emergence of a core-periphery structure in a simple dynamic model of the interbank market

This paper studies a simple dynamic model of interbank credit relationships. Starting from a given balance sheet structure of a banking system with a realistic distribution of bank sizes, the necessity of establishing interbank credit connections emerges from idiosyncratic liquidity shocks. Banks initially choose potential trading partners randomly, but over time form preferential relationships via an elementary reinforcement learning algorithm. As it turns out, the dynamic evolution of this system displays a formation of a core-periphery structure with mainly the largest banks assuming the roles of money center banks mediating between the liquidity needs of many smaller banks. Statistical analysis shows that this evolving interbank market shares the majority of the salient characteristics of interbank credit relationship that have been put forth in recent literature. Preferential interest rates for borrowers with strong attachment to a lender may prevent the system from becoming extortionary and guarantee the survival of the small peripherical banks.     

Discounting inflation — a note

The aim of this paper is to clarify the confused issue of the effect of inflation on the discounting procedure for investment appraisal. The standard approach is considered, together with the impact of inflation, and the problem of how to adjust the standard approach to take account of inflation. The point is made that it is usually easiest to estimate expected returns in current prices, in which case the discount rate should reflect the real opportunity cost of capital, to avoid mixing real returns and nominal interest in a manner which leads to the rejection of worthwhile projects. An example is given of how the real rate of interest can be computed from the nominal rate of interest and the rate of inflation, and the difference this makes to discounting a sample project. The paper then illustrates how real rates of interest have frequently been negative over the past decade and how this implies that projects may be acceptable even if the sum of future undiscounted returns is less than the initial outlay. The conclusion drawn is that investors should maximize economic profit defined as the surplus over opportunity cost, which reduces the deterrent of nominally high interest rates, for the maximization of surplus over opportunity cost has the corollary of minimization of opportunity loss.     

Real Balances, the Price Level and the Unit of Account

A bstract It is argued that Patinkin's introduction in his 1956 book of the stability analysis of the price level resulted in great measure from his reading of Wicksell's 1898 Interest and Prices. Both Patinkin and Wicksell based their treatments of the stability of the price level on what Patinkin used to call the "real balance effect." That effect, however, does not operate under Wicksell's assumption of a competitive "pure credit economy", where all transactions are carried out by bookkeeping transfers, and the unit of account is the same unit in which the accounts of banks are kept. In that case, Patinkin showed in the second (1965) edition of his book that the real balance effect–and, by that, the stability of the price level–would still be a feature of the system if profit maximizer banks held reserves, created by the central bank to settle temporary imbalances at the clearinghouse. According to Wicksell, on the other hand, a pure credit economy should consist of a central bank that attracts and remunerates deposits at the same interest rate charged for its loans, plus profit maximizer financial intermediaries that lend money for risky projects. The basic rate of interest set by the central bank decides, accordingly, the price level in such an economy. Wicksell's and Patinkin's approaches differ from the view put forward in the 1980s by the so-called "new monetary economics" that the key to price level stabilization is the separation of the function of money as the unit of account from its function as the medium of exchange in pure accounting systems of exchange.     

Towards estimating the demand for money in China

The demand for money in China is estimated separately for the periods before and after the economic reform. Besides the traditional transactions demand variable, the expected rate of inflation (as a measure of the opportunity cost of holding money) and the monetization process are also incorporated into the demand function. The preliminary results show that the demand for money in China has changed in response to the institutional changes during the economic reform. Adding the monetization and inflation expectation variables into the money demand function has enhanced significantly its explanatory power.

Money and velocity during financial crises: From the great depression to the great recession

This study models the demand for a broad monetary aggregate (M2) from the Great Depression through the Great Recession. Key to the model is the interaction between a measure of time-variation in economic agents’ perceived financial risk and an index of the cost of portfolio adjustment. The finding of a useful money demand relationship suggests that skepticism regarding the indicator role of a broad, liquid money aggregate as a policy guide may be exaggerated. Further, our model provides some guidance for policymakers who face the challenge of unwinding large balance sheets as risk premia return to normal and velocity adjusts.     

Wicksell on the Classical Theories of Money, Credit, Interest and the Price Level:

ABSTRACT Knut Wicksell occupies a significant place in the history of monetary economics as the developer of the "cumulative process" by which deviations between the market and "natural" rates of interest cause the price level to change persistently. A more accurate version of the same argument is a part of classical monetary analysis but there the process originates from a change in base money or central bank credit while Wicksell's version may be initiated by banks capriciously setting their lending rates. Wicksell's version arises from his difficulties in correctly interpreting the classical quantity theory of money and interest rate determination from Hume down to Marshall, but has not been so noted in the literature.     

Volunteering time decisions: a multi‐factor experimental study

Non‐profit organizations often seek volunteers to help staff a fundraising event. In the present research, an experimental study assessed volunteering time decisions for a fundraising event following manipulations of opportunity cost valence, opportunity cost avoidability and question order involving donating time and donating money. Opportunity costs represent foregone alternatives sacrificed (e.g. working) when engaging in an activity (e.g. volunteering), with valence of the opportunity cost indicating the appeal (positive or negative) of the foregone alternative and avoidability of the opportunity cost suggesting how easy it would be to forgo the alternative. Prospective donors are often asked to consider both volunteering time and contributing money, and these two questions posed to individuals can be varied in terms of order. The results of the experiment revealed that individuals intended to volunteer the most time when an opportunity cost was negative and avoidable. The lowest time donation intentions occurred when an opportunity cost was positive and less avoidable with individuals also being asked about donating money prior to being asked to donate time. The results highlighted the importance to non‐profit firms of considering opportunity costs potential volunteers face and suggested care in structuring the order of questions involving time and money posed to those individuals.

Costly State Verification with Varying Risk Preferences and Liability

Abstract.  In the scenario of loan contracts with costly state verification, we examine how the properties of the set of states, different risk preferences of debtors and varying liability of lenders affect the structure of optimal repayments. In particular, we show that with risk‐averse debtors, a general set of states, a constant observation cost and both unlimited and limited lender liability, the debtor is strictly better off revealing the true state of nature when his realized revenue is low, which implies that optimal debtor consumption has a downward jump around the single switch from observed to unobserved states. If the debtor can destroy revenue or if the debtor is risk neutral, this non‐monotonicity of consumption disappears. Moreover, given the loan size, there is more monitoring under debtor‐risk aversion than risk neutrality. We present simulations showing that a contract with unlimited lender liability and debtor‐risk aversion has a higher expected observation cost but a lower variance of consumption than a contract with limited lender liability. Finally, we discuss the problems of commitment to verification and contract renegotiation in this framework.

Bargaining and exclusivity in a borrower–lender relationship

This paper presents a stylized model of a borrower–lender relationship where funds are gradually invested in a project with uncertain return. We show that an exclusive financing relationship arises endogenously in equilibrium due to initial lender’s superior information on the project’s progress. The analysis also identifies a novel distortionary effect of exclusivity and the consequent loss of future rents on the ex-ante choices of the borrower. When she chooses the amount of funds to be initially invested in the project, the borrower chooses to overinvest making the future rent extraction by the initial lender as costly as possible.
