Aging, myopia and the pay-as-you-go public pension systems of the G7: a bright future?

The public pension systems of the G7 countries were established in an era when the number of contributors far outweighed the number of beneficiaries. Now, for each beneficiary there are fewer contributors, and this trend is projected to accelerate. To evaluate the prospects for these economies we develop an overlapping generations model where growth is endogenously fueled by investments in physical and human capital. We analyze individuals' behavior when their expectations over their length of life are rational or myopic and examine whether policies exist that can offset the effects of aging, should they be adverse. We find that while perfectly anticipated aging is welfare improving and does not threaten the solvency of public pension systems, myopia worsens welfare, puts pension systems at risk, and cannot be easily remedied by public policy.Social security

Banks vs. credit unions; dynamic competition in local markets

One interesting aspect of the financial services industry is that for-profit institutions such as commercial banks compete directly with not-for-profit financial intermediaries such as credit unions. In this article, we analyze competition among banks and between banks and credit unions using a dynamic model of spatial competition. The model allows for the co-existence of (for-profit) banks and (not-for-profit) credit unions. Using annual county-level data on banking market concentration and credit-union participation rates for the period 1989-96, we find empirical evidence of two-way competitive interactions between banks and credit unions.Credit unions ; Bank management

The dynamic relationship between the federal funds rate and the Treasury bill rate: an empirical investigation

This article examines the dynamic relationship between two key U.S. money market interest rates - the federal funds rate and the 3-month Treasury bill rate. Using daily data over the period 1974 to 1999, we find a long-run relationship between these two rates that is remarkably stable across monetary policy regimes of interest rate and monetary aggregate targeting. Employing a non-linear asymmetric vector equilibrium correction model, which is novel in this context, we find that most of the adjustment towards the long-run equilibrium occurs through the federal funds rates. In turn, there is strong evidence for the existence of significant asymmetries and nonlinearities in interest rate dynamics that have implications for the conventional view of interest rate behavior.Interest rates ; Arbitrage ; Treasury bills

Do real exchange rates have autoregressive unit roots? a test under the alternative of long memory and breaks

In this paper, we estimate (by maximum likelihood) the parameters of univariate fractionally integrated real exchange rate time series models, and test for autoregressive unit roots on the alternative of a covariance stationary long-memory process. We use quarterly dollar-based real exchange rates (since 1957) for seventeen OECD countries, and that the finding of unit autoregressive roots does not go away even with this more sophisticated alternative.Foreign exchange rates ; Time-series analysis

The practice of central bank intervention: looking under the hood

This article first reviews methods of foreign exchange intervention and then presents evidence - focusing on survey results - on the mechanics of such intervention. Types of intervention, instruments, timing, amounts, motivation, secrecy and perceptions of efficacy are discussed.Banks and banking, Central ; Foreign exchange ; Monetary policy

The role of a CAMEL downgrade model in bank surveillance

This article examines the potential contribution to bank supervision of a model designed to predict which banks will have their supervisory ratings downgraded in future periods. Bank supervisors rely on various tools of off-site surveillance to track the condition of banks under their jurisdiction between on-site examinations, including econometric models. One of the models that the Federal Reserve System uses for surveillance was estimated to predict bank failures. Because bank failures have been so rare during the last decade, the coefficients on this model have been "frozen" since 1991. Each quarter the surveillance staff at the Board of Governors provide the supervision staff in the Reserve Banks the probabilities of failure by the banks subject to Fed supervision, based on the coefficients of this bank failure model and the latest call report data for each bank. The number of banks downgraded to problem status in recent years has been substantially larger than the number of bank failures. During a period of few bank failures, the relevance of this bank failure model for surveillance depends to some extent on the accuracy of the model in predicting which banks will have their supervisory ratings downgraded to problem status in future periods. This paper compares the ability of two models to predict downgrades of supervisory ratings to problem status: the Board staff model, which was estimated to predict bank failures, and a model estimated to predict downgrades of supervisory ratings. We find that both models do about as well in predicting downgrades of supervisory ratings for the early 1990s. Over time, however, the ability of the downgrade model to predict downgrades improves relative to that of the model estimated to predict failures. This pattern reflects the value of using a model for surveillance that can be re-estimated frequently. We conclude that the downgrade model may prove to be a useful supplement to the Board's model for estimating failures during periods when most banks are healthy, but that the downgrade model should not be considered a replacement for the current surveillance framework.Bank supervision

The value of inside and outside money

We study dynamic economies in which agents may have incentives to hold both privately-issued (a.k.a. inside) and publicly-issued (a.k.a. outside) circulating liabilities as part of an equilibrium. Our analysis emphasizes spatial separation and limited communication as frictions that motivate monetary exchange. We isolate conditions under which a combination of inside and outside money does and does not allow the economy to achieve a first-best allocation of resources. We also study the extent to which the use of private circulating liabilities alone, or the use of public circulating liabilities alone, can address the frictions that lead to monetary exchange. We identify conditions under which both types of liabilities are essential to efficiency. However, even when these conditions are satisfied, we show that political economy considerations may lead to a prohibition against private circulating liabilities. Finally, we analyze the consequences of such a prohibition for the determinacy of equilibrium, and for endogenously arising volatility.Money ; Money theory

Pricing and dividend policies in open credit cooperatives

This paper develops an integrated model of pricing and dividend policies in open credit cooperatives (those that do business with members and non-members on a non-discriminatory basis). We show that both the distribution of member preferences and the amount of non-member business the cooperative does influence its optimal pricing and dividend policies. For a fixed distribution of member preferences, the larger the fraction of business done by members, the smaller the optimal dividend and the larger the optimal pricing subsidy (hence, increasing demand). On the other hand, for a fixed fraction of member business, the greater the skewness of member preferences toward loan (deposit) business with the credit cooperative, the larger the optimal dividend and the higher (lower) the optimal loan (deposit) interest rate. Aggregate empirical evidence from the German cooperative banking sector supports a version of the latter prediction, namely, that in an increasingly depositor-dominated open credit cooperative, average deposit rates tend to fall as dividend payouts rise.Credit unions ; Prices ; Dividends

A simple model of international capital flows, exchange rate risk, and portfolio choice

This paper examines international capital flows in the context of a simple Diamond-Dybvig model in which there are neither moral hazard nor adverse selection problems, thus isolating exchange rate risk as the propagator of capital flows. The model shows that adverse changes in exchange rate expectations can result in "hot money" flows even when a bank's balance sheet is perfectly transparent and its assets have a positive net present value in local currency terms. The model also indicates that foreign deposit guarantees even in the absence of a change in the bank's portfolio can increase the chance of bank runs.Capital movements ; Foreign exchange

The domestic adjusted monetary base

This paper provides a consistent, monthly measure of the amount of the U.S. adjusted monetary base that is domestically held, and of the amount held abroad. Most macroeconomic models that address the role of outside money as a determinant of the economy's aggregate price level are closed economy models, suggesting a need to accurately measure the domestic monetary base. To do so, this paper presents a new method to estimate the amount of U.S. currency held abroad, a method which exploits data on the processing of currency at the Federal Reserve's 37 cash offices. Estimates of domestic monetary aggregates, including domestic M1 and M2, also are produced. Relative to previous studies and estimates currently included in the Flow of Funds and the National Income and Product Accounts, our estimates suggest larger currency exports during the 1970s and early 1980s, and a sharp slowing of exports since 1995.Money supply ; Money ; Dollar, American
