The monetary policy dilemma: Will interest rates have to rise?

UK interest rates are now at their lowest level for more than two decades, and the government is hoping that interest rates can be kept at a low and sustainable level comparable to the 1960s. Indeed, some commentators are calling for still lower interest rates to offset the risk that the £12bn tax increases and cuts in government spending that will come into effect in the next financial year will lead to stagnant consumer spending and a stalled recovery. Against this must be weighed the risk that the recent very good run of inflation figures will prove temporary. Both headline and underlying inflation will be pushed up by indirect tax increases and there is the possibility that wages will follow too, as employees seek to maintain their living standards in a tightening labour market. That risk would point to a much more cautious monetary policy stance and the possibility that the government may need to raise rates from their present level if it is to achieve its inflation objective. The Chancellor faces a clear dilemma. In this Viewpoint, we assess the evidence available to guide him in his decisions and draw out the implications for the future path of interest rates.     

JAPANESE ANTITRUST: RECONCILING THEORY AND EVIDENCE

Japanese antitrust law exempts a variety of vertical and horizontal restraints that remain closely regulated in the United States. Despite these dissimilar antitrust environments, however, market concentration, firms' exercise of market power, and deadweight loss from monopoly are highly similar in the two countries. The hypothesis that antitrust alters the relative mix of price to non-price competition rather than the absolute level that competition assumes might explain this empirical puzzle. Thus, this paper studies Japanese antitrust exemptions for resale price maintenance and export cartel associations to illustrate how adopting vertical and horizontal restraints has allowed Japanese firms to substitute towards forms of non-price competition better tailored to industry characteristics.

Federal Deposit Insurance,Regulatory Policy,and Optimal Bank Capital*

This paper seeks to explain the combination of explicit and implicit pricing for deposit insurance employed by the FDIC. Essentially, the FDIC sells two products—insurance and regulation. To span the product space, it must and does set two prices. We argue that the need to establish regulatory disincentives to bank risk-taking is the heart of the controversy over the adequacy of bank capital and that the ability to close risky banks before exhausting their charter value (i.e., the value of their right to continue in business) stands at the center of these disincentives and in front of the FDIC's insurance reserves.     

A Practical Framework for the Analysis of Social Security Reform

A Nonparametric Approach to Pricing and Hedging Derivative Securities Via Learning Networks

We propose a nonparametric method for estimating the pricing formula of a derivative asset using learning networks. Although not a substitute for the more traditional arbitrage-based pricing formulas, network-pricing formulas may be more accurate and computationally more efficient alternatives when the underlying asset's price dynamics are unknown, or when the pricing equation associated with the no-arbitrage condition cannot be solved analytically. To assess the potential value of network pricing formulas, we simulate Black-Scholes option prices and show that learning networks can recover the Black-Scholes formula from a two-year training set of daily options prices, and that the resulting network formula can be used successfully to both price and delta-hedge options out-of-sample. For comparison, we estimate models using four popular methods: ordinary least squares, radial basis function networks, multilayer perceptron networks, and projection pursuit. To illustrate the practical relevance of our network pricing approach, we apply it to the pricing and delta-hedging of S&P 500 futures options from 1987 to 1991.     

Trading Volume: Implications of an Intertemporal Capital Asset Pricing Model

We derive an intertemporal asset pricing model and explore its implications for trading volume and asset returns. We show that investors trade in only two portfolios: the market portfolio, and a hedging portfolio that is used to hedge the risk of changing market conditions. We empirically identify the hedging portfolio using weekly volume and returns data for U.S. stocks, and then test two of its properties implied by the theory: Its return should be an additional risk factor in explaining the cross section of asset returns, and should also be the best predictor of future market returns.     

The Integration of Insurance and Taxes in Corporate Pension Strategy

This paper examines the implications of the joint effects of insurance and taxes for the optimal corporate pension strategy. It is shown that neither the “mini-max” nor the “maxi-min” strategy advocated by previous authors is necessarily best in corporate pension management. In the presence of capital market imperfections, the analysis via a single-period contingent-claims model indicates that optimal corporate pension strategy in both asset-allocation and funding decisions can be a noncorner interior solution.     

Is the Real Interest Rate Stable?

Univariate time-series models for consumption, nominal interest rates, and prices each appear to have a single unit root before 1979. If nominal interest rates have a unit root but inflation and inflation forecast errors do not, then ex ante real interest rates have a unit root and are therefore nonstationary. This deduction does not depend on the properties of the unobservable ex post observed real return, which combines the ex ante real interest rate and inflation-forecasting errors. The unit-root characteristic of real interest rates is puzzling from at least two perspectives: many models imply that the growth rate of consumption and the real interest rate should have similar time-series characteristics; also, nominal returns for other assets (e.g., stocks and bonds) appear to have different times-series properties from those of treasury bills.
