Stock Exchange Reforms and Market Efficiency: the Italian Experience

This paper examines whether the reforms introduced by the Italian Stock Exchange from 1991 to 1994 (creation of specialised intermediaries, obligation to trade on the official markets, screen-based trading and cash settlement) did increase market efficiency. The issue is addressed using both the traditional information efficiency model, which tests market efficiency by verifying the predictability of prices conditional on some information subset, and a microstructure approach that measures efficiency as the distance of the price movements from their efficient components, represented by a random walk process. The joint analysis of daily and intraday data on prices and volumes validates the hypothesis that most of the reforms have increased market efficiency over the sample period, except for cash settlement, which appears to have substantially reduced it.     

Optimal Price and Selling Effort from the Perspectives of the Broker and Seller

This paper uses numerical solutions of a dynamic optimization model to examine the principal-agent relationship between the seller and broker in residential real estate markets. Potential conflict of interest is quantified in two dimensions, the level of selling effort the broker puts forth, and the reservation price for the property. The dynamic optimization model reveals that the use of a finite duration listing contract will induce the broker to increase his or her effort level compared to an unlimited duration contract, and that the broker's optimal effort will increase over time, becoming greater as the listing contract expiration time draws nearer ("rational procrastination"). The numerical analysis indicates that with plausible parameter values, conflict of interest problems regarding broker effort level are minor or nonexistent near the end of the listing contract, but potentially important near the beginning of the contract. In contrast, the conflict of interest regarding reservation price is more severe near the end of the listing contract and is exacerbated by the use of finite duration contracts, the more so the shorter the contract.     

Organizations as learning systems: The case of the Japanese automobile manufacturing industry

This study sought to apply frameworks of organizational learning to companies in the Japanese automobile manufacturing industry and, in the process, to ascertain if Japanese automobile companies exhibit characteristics of high- versus low-learning organizations. Of particular interest are the effects of Japanese culture on organizational behavior. A basis for empirical testing of concepts of organizational learning to establish an explanation as to why some companies are more effective in succeeding in the global market according to accepted measures of success is provided. © 1995 John Wiley & Sons, Inc.     

AN ILLUSTRATIVE PRODUCTION FUNCTION FOR LABOUR-MANAGED FIRMS*

An illustration of the ambiguities in the behaviour of a labour-managed firm in the long run when both capital and labour are variable is provided by means of an example which can be completely solved. Input demand and output supply functions are derived from a suggested production function. The special case of a homothetic production function is yielded by one of five parameter sets identified.

The next forty years : A reprise

The following paper is a republication of the introductory pages to Norman Macrae's book, The Next Forty Years, published by The Economist in 1972. Each year, Norman Macrae, deputy-editor of The Economist, researched and wrote a lengthy survey on a subject about which he claimed little, if any, expert knowledge. In 1971 Macrae tried to turn himself into a business futurologist. Based on interviews with industrialists and using relevant literature about multinational corporations and business, Macrae attempted to forecast the most logical course for international business trends and organization between 1972 and 2012, and especially 1972–1992. Some of his views were highly unconventional, and deliberately so. More than 20 years later, his views still often seem controversial, but are as relevant as ever.
