Knowledge that Transforms

Banks play a greater role in the German financial system than in those of the United States or Britain. Germany's large universal banks are admired by those who advocate bank deregulation in the United States. Others admire the universal banks for their supposed role in corporate governance and industrial finance. Many discussions distort the German banking system by overstressing one of several types of banks, and ignore the competition and cooperation between the famous universal banks and other banking groups. Tracing the historical development of the German banking system from the early nineteenth century places the large universal banks in context.

Citation patterns between 42 journals in economics from 1995 to 1997 are examined, plus between economics and anthropology, political science, psychology, sociology and five business disciplines. Building on social network theory, we identify a hierarchical organization of journals in economics and seven journal clusters. Major citation flows are found from all areas of economics to the general interest and theory and method clusters, but not the other way around. Economics emerges as a significant source of interdisciplinary knowledge for the other social sciences and business. However, no area of economics appears to build substantially on insights from its sister disciplines.

This essay surveys macroeconomic issues that marked the transition from centrally planned to market economy in Central and Eastern European and former Soviet Union countries. We first establish a set of stylized facts of the transition so far, namely: (1) output fell, (2) capital shrank, (3) labour moved, (4) trade reoriented, (5) the structure changed, (6) institutions collapsed, and (7) the transition costs. We then critically survey the theoretical literature on transition, discussing various explanations for the initial output fall as well as medium term issues, such as optimal speed of transition, disorganization, institutions and sectoral reallocation as a source of output dynamics. Last, we review the empirical literature to assess how well it translates the theoretical models and explains the stylized facts. The essay concludes with a succinct list of suggestions for future research.

Since 1947, hyperinflations in market economies have been rare. More common have been longer inflationary processes at rates above 100 percent per annum. This paper examines the main characteristics of such very high inflation episodes. We find that (i) almost 20 percent of countries have experienced such episodes; (ii) higher inflation is more unstable; (iii) in high-inflation countries, the relationship between the fiscal balance and seigniorage is strong; (iv) inflation inertia decreases as average inflation rises; (v) high inflation is associated with poor macroeconomic performance; and (vi) stabilizations that rely on the exchange rate as the nominal anchor are expansionary.

This paper reviews the economics literature on welfare reform over the 1990s. A brief summary of the policy changes over this period is followed by a discussion of the methodological techniques utilized to analyze the effects of these changes on outcomes. The paper then critically reviews the econometric and experimental literature on caseload changes, labor force changes, poverty and income changes, and family formation changes. A growing body of evidence suggests that the recent policy changes have influenced economic behavior and well-being in a variety of ways. One particular set of "new-style" welfare programs seems to show especially promising results, with significantly increased work and earnings and reduced poverty.

We survey the empirical literature analysing the process of enterprise restructuring in transition economies. The survey provides new insights into the relative effectiveness of different reform policies, and into how this effectiveness varies across regions. We study the effects of privatization, the importance of different types of owners, the effects of foreign and domestic competition, the consequences of soft budgets, and the role of managerial incentives and managerial human capital, on enterprise restructuring.
