The Efficiency and Stability of Banks and Markets

Traditionally, financial systems have been bank-based or market-based. The efficiency properties of these systems are compared in various dimensions. These include risk sharing, information provision, funding new industries, corporate governance, and law, finance and politics. Both systems have advantages and disadvantages. With regard to stability, both bank-based and market-based systems are subject to crises. Going forward a financial system with financial intermediaries and markets would have many advantages and few disadvantages.

The Future of the Japanese Financial System

The purpose of this paper is to consider the strengths and weaknesses of the Japanese financial system and to propose possible changes for the future. The apparent reversal in opinions on the effectiveness of the Japanese and US financial systems in recent years suggests a long term view should be taken. All financial systems have problems in the short term and it is important not to put too much weight on these. Section 2 briefly considers the historical development and the current differences between the Japanese and US financial systems. Section 3 considers the functions of a financial system and how the Japanese and US systems have performed these functions. Suggestions for reforms for Japan are outlined in Section 4 and Section 5 contains concluding remarks. This paper was presented at the Financial Institutions Center's October 1996 conference on "

Mark-to-market accounting and liquidity pricing

When liquidity plays an important role as in times of financial crisis, asset prices in some markets may reflect the amount of liquidity available in the market rather than the future earning power of the asset. Mark-to-market accounting is not a desirable way to assess the solvency of a financial institution in such circumstances. We show that a shock in the insurance sector can cause the current value of banks’ assets to be less than the current value of their liabilities so the banks are insolvent. In contrast, if historic cost accounting is used, banks are allowed to continue and can meet all their future liabilities. Mark-to-market accounting can thus lead to contagion where none would occur with historic cost accounting. Klassifizierung: G21, G22, M4

Diversity of Opinion and Financing of New Technologies

The objective is to compare the effectiveness of financial markets and financial intermediaries in financing new industries and technologies in the presence of diversity of opinion. In markets, investors become informed about the details of the new industry or technology and make their own investment decisions. In intermediaries, the investment decision is delegated to a manager. She is the only one who needs to become informed, which saves on information costs, but investors may anticipate disagreement with her and be unwilling to provide funds. Financial markets tend to be superior when there is significant diversity of opinion and information is inexpensive.

Credit Risk Transfer and Contagion

Some have argued that recent increases in credit risk transfer are desirable because they improve the diversification of risk. Others have suggested that they may be undesirable if they increase the risk of financial crises. Using a model with banking and insurance sectors, we show that credit risk transfer can be beneficial when banks face uniform demand for liquidity. However, when they face idiosyncratic liquidity risk and hedge this risk in an interbank market, credit risk transfer can be detrimental to welfare. It can lead to contagion between the two sectors and increase the risk of crises.Financial Innovation, Pareto Inferior, Banking, Insurance

Corporate Governance and Competition

The corporate governance systems operating in different countries are distinct. In the U.S. and U.K., it is often argued that the threat of takeover ensures managers act in the shareholders' interests. In countries such as Germany, Japan, and France, it is suggested banks and other institutions act as monitors. There is some evidence that neither system is particularly effective. We argue that competition among firms may be more effective than either of these mechanisms in ensuring that resources are used efficiently.

Comparative Financial Systems: A Survey

What is a Financial System? The purpose of a financial system is to channel funds from agents with surpluses to agents with deficits. In the traditional literature there have been two approaches to analyzing this process. The first is to consider how agents interact through financial markets. The second looks at the operation of financial intermediaries such as banks and insurance companies. Fifty years ago, the financial system could be neatly bifurcated in this way. Rich households and large firms used the equity and bond markets, while less wealthy households and medium and small firms used banks, insurance companies and other financial institutions. Table 1, for example, shows the ownership of corporate equities in 1950. Households owned over 90 percent. By 2000 it can be seen that the situation had changed dramatically. By then households held less than 40 percent, nonbank intermediaries, primarily pension funds and mutual funds, held over 40 percent. This change illustrates why it is no longer possible to consider the role of financial markets and financial institutions separately. Rather than intermediating directly between households and firms, financial institutions have increasingly come to intermediate between households and markets, on the one hand, and between firms and markets, on the other. This makes it necessary to consider the financial system as an irreducible whole. The notion that a financial system transfers resources between households and firms is, of course, a simplification. Governments usually play a significant role in the financial system. They are major borrowers, particularly during times of war, recession, or when large infrastructure projects are being undertaken. They sometimes also have significant amounts of funds. For example, when countries such as Norway and many Middle Eastern States have access to large amounts of natural resources (oil), the government may acquire large trust funds on behalf of the population. In addition to their roles as borrowers or savers, governments usually play a number of other important roles. Central banks typically issue fiat money and are extensively involved in the payments system. Financial systems with unregulated markets and intermediaries, such as the US in the late nineteenth century, often experience financial crises (Gorton (1988) and Calomiris and Gorton (1991)). The desire to eliminate these crises led many governments to intervene in a significant way in the financial system. Central banks or some other regulatory authority are charged with regulating the banking system and other intermediaries, such as insurance companies. So in most countries governments play an important role in the operation of financial systems. This intervention means that the political system, which determines the government and its policies, is also relevant for the financial system. There are some historical instances where financial markets and institutions have operated in the absence of a well-defined legal system, relying instead on reputation and other implicit mechanisms. However, in most financial systems the law plays an important role. It determines what kinds of contacts are feasible, what kinds of governance mechanisms can be used for corporations, the restrictions that can be placed on securities and so forth. Hence, the legal system is an important component of a financial system. A financial system is much more than all of this, however. An important pre-requisite of the ability to write contracts and enforce rights of various kinds is a system of accounting. In addition to allowing contracts to be written, an accounting system allows investors to value a company more easily and to assess how much it would be prudent to lend to it. Accounting information is only one type of information (albeit the most important) required by financial systems. The incentives to generate and disseminate information are crucial features of a financial system. Without significant amounts of human capital it will not be possible for any of these components of a financial system to operate effectively. Well-trained lawyers, accountants and financial professionals such as bankers are crucial for an effective financial system, as the experience of Eastern Europe demonstrates. The literature on comparative financial systems is at an early stage. Our survey builds on previous overviews by Allen (1993), Allen and Gale (1995) and Thakor (1996). These overviews have focused on two sets of issues. Normative: How effective are different types of financial systems at various functions? Positive: What drives the evolution of the financial system? The first set of issues of considered in sections 2-6, which focus on issues of investment and saving, growth, risk sharing, information provision and corporate governance, respectively. Section 7 considers the influence of law and politics on the financial system while Section 8 looks at the role financial crises have had in shaping the financial system. Section 9 contains concluding remarks.
