Knowledge that Transforms

Over the last decade, there has been considerable public debate in the U.S. on the need to maintain legal barriers (firewalls) between commercial and non-traditional banking. However, no theoretical model has yet been developed that examines the joint influence of various factors suggested, such as competition, production economies and regulatory subsidies that affect the bank's incentive to undertake non-traditional activities. This paper applies a stochastic control model to examine the joint effects of these factors on a bank's optimal investment decisions in non-traditional banking and develops some empirically testable hypotheses.

In this paper, we investigate the magnitude of the benefits from international diversification from the Nordic point of view. Special attention is paid to whether potentially increased co-movement of stock markets together with more volatile Nordic currencies have resulted in decreased benefits from international diversification towards the end of the 1980s. Moreover, the paper presents evidence on the benefits from international diversification for a currency which has recently started its free float, the Finnish markka (FIM). We find significant increases in stock market co-movement. Both unhedged ex ante strategies as well as strategies hedged for exchange rate risk are investigated, revealing substantial benefits from international diversification for the Nordic countries. However, we obtain mixed results concerning the question of the optimality of hedging.

This paper discusses seigniorage in an economy with imperfect competition in the banking sector. The amount of total seigniorage and its division between the central bank and the banking sector are derived by using the opportunity cost concept of seigniorage. The paper analyzes the impact of changes in inflation, reserve requirements, competition and technology on the division of seigniorage and on the welfare loss and relates the analysis to the concept of the optimal quantity of money.

This paper tests the hypothesis that banks with more risky loans and higher interest-rate risk exposure would select loan and deposit rates to achieve higher net interest margins. Call Report data for different size classes of banks for 1989–1993 show that the net interest margins of commercial banks reflect both default and interest-rate risk premia. The net interest margins of money-center banks are affected by default risk, but not by interest rate risk, which is consistent with their greater concentration in short-term assets and off-balance sheet (OBS) hedging instruments. By contrast, (super-) regional banking firms are sensitive to interest-rate risk but not to default risk. The data show that OBS activities promote a more diversified, margins-generating asset base than deposit- or equity-financing, and that cross-sectional differences in interest-rate risk and liquidity risk are related to differences in OBS exposure.

For many years, Government of Canada bonds with high coupons traded at much higher yields than those with lower coupons. This apparent market inefficiency virtually disappeared over a short period of time during 1993. Several events occurred in 1993 which relate to the narrowing of the spread. This paper shows the earlier yield spread to be consistent with restrictions on the trading of strip bonds. It also finds it difficult to defend the hypothesis that the higher yield spread represented unexploited profit opportunities.

We examine voluntary acquisitions of solvent stock-held thrift institutions since 1979, and find that bidding firms suffered losses, target firms gained, and the impact of the merger on the bidder-target pair was positive on average. During the post-FIR-REA period acquirers experienced smaller losses and targets experienced smaller gains relative to the pre-FIRREA period. An investigation into the motives of bidding firm management provides evidence indicating the presence of synergy, agency, and hubris motivations in the pre-FIRREA period. Although the acquisitions environment underwent substantial changes in the post-FIRREA period, we find no evidence of corresponding changes in acquisition motivations.

This paper develops a geometric methodology with which to analyze the no-arbitrage condition, with special reference to tax arbitrage in government bonds. Using this methodology, it is shown that a country's bond-issuing authority might be able to painlessly avoid market equilibria which is likely to induce tax arbitrage activities. The simple bond-issuing policy which will achieve this goal is identified, and its limitations are discussed. An examination of the Canadian and Israeli bond markets shows that adopting the prescribed bond-issuing policy does not meaningfully impinge on the bond-issuing authority's ability to sell bonds.

The Pension Benefit Guaranty Corporation (PBGC), which insures private defined benefit pension plans, is facing mounting deficits. The main cause of this predicament for PBGC can be traced down to the misuse of the insurance by a few companies. We therefore propose an active intervention policy - which would result in termination of severely underfunded plans — for the PBGC. A continuous-time model is provided to help determine the point of intervention, if necessary, using option-pricing techniques. A clear exposition of the intervention doctrine is thus obtained via this model. We also provide a numerical illustration of the working of the model on a hypothetical pension plan.

New evidence is provided on price and volatility spillovers among the Danish, Norwegian, Swedish, and Finnish stock markets. The impact of good news (market advances) and bad news (market retreats) is described by a multivariate Exponential Generalized Autoregressive Conditionally Heteroskedastic (EGARCH) model. Volatility transmission is asymmetric, spillovers being more pronounced for bad than good news. Significant price and volatility spillovers exist but they are few in number.

The market for credit cards has been the subject of recent attention and controversy because of ‘high’ profits earned on credit cards and substantial premiums on the resale of credit-card receivables. This paper estimates risk—return profiles for credit-card banks and explores the role of intangible assets in determining resale premiums on credit-card receivables. In addition, the effects on the resale market of securitization and the opportunity cost of acquiring new accounts are analyzed. Using alternative measures of risk and alternative control groups, we find, for the years 1989 to 1995, that credit-card banks earned significantly higher returns on assets but that these returns were associated with greater risk-taking. Analysis of premia for the years 1993 to 1995 suggest that acquiring banks pay higher premia for mid-sized regional accounts than for larger, national portfolios, perhaps because of richer cross-selling opportunities.
