The optimum size of the labor-managed firm

Ward's [1958] main result is that an increase in the output price of the labor-managed firm (LMF) decreases its output and members. However, Ward and his followers have not addressed two important elements: the benefit of sharing a public good among LMF members and the increased coordination costs among these members. This paper incorporates these elements to derive the LMF's optimal size and suggests conditions which may alter Ward's perverse result. The example of the Israeli Kibbutzim concerning both incorporating the public goods as well as coordination costs serves as a motivation to the model developed in this paper.     

Financial Turbulence and the Japanese Main Bank Relationship

Under the Japanese main bank relationship, a bank holds equity in a firm and plays a leading role in its decision-making and financing. This may leave a firm dependent on its main bank for financing due to its information advantage over other potential lenders. This dependency may be particularly severe during episodes of financial turbulence. We examine the sensitivity of returns on portfolios of Japanese firm equity to the returns of their main banks using a three-factor arbitrage-pricing model. We find no significant dependence when coefficient values are held constant over the entire sample. However, the data strongly suggest a structural break in the relationship subsequent to the last quarter of 1997, a turbulent period for Japanese financial markets. When a structural break is introduced, main bank sensitivity increases after the break, usually to significantly positive levels.     

A comment on the role of prices for excludable public goods

Blomquist and Christensen [(2005). The role of prices for excludable public goods, International Tax and Public Finance, 12 ,61–79] argue that welfare is initially decreasing in the price of an excludable public good and that the case for a positive price for an excludable public good price is weak. We argue that this result follows from their particular characterization of the public good and that an alternative and equally reasonable characterization overturns their result. Hence, the policy case for a positive price on the public good is stronger than Blomquist and Christiansen suggest. JEL Classification H21 · H41     

Market price accounting and depositor discipline: The case of Japanese regional banks

We examine the determinants of Japanese regional bank pricing-to-market decisions and their impact on the intensity of depositor discipline, in the form of the sensitivity of deposit growth to bank financial conditions. To obtain consistent estimates, we first model and estimate the bank pricing-to-market decision and then estimate the intensity of depositor discipline after conditioning for that decision. We find that banks were less likely to adopt market price accounting the larger were their unrealized securities losses. We also find statistically significant evidence of depositor discipline among banks that elected to price to market. Our results indicate that depositor discipline was more intense for the subset of banks that adopted market price accounting.     

展望“里约＋20峰会”把握企业可持续发展趋势

1992年，联合国在巴西里约热内卢举办了联合国环境和发展大会，有183个国家的代表出席。当时各国已感受到生态破坏的威胁，推动了一系列的国际条约以及新的承诺，并正式提出了可持续发展的理念。时隔20年，“联合国可持续发展大会”将于今年6月在巴西里约热内卢举行，因此也被称为“里约＋20峰会”。     

Personal characteristics of salespeople and the attractiveness of alternative rewards

How do personal characteristics of salespeople affect their desire for the various rewards available to them? Do younger salespeople desire different types and levels of rewards than older salespeople? Are there differences due to job tenure, marital status, family size, and so forth? In this article, the authors attempt to answer these questions. Based on an extensive investigation of the industrial sales forces from two large companies, the authors examine the relationship between personal characteristics and the sales force's valence for various rewards. Although some of the findings are consistent with current sales management practices, some are not, suggesting that present day thinking with respect to the design and administration of rewards may need more careful scrutiny.     

The Risk Map: A new tool for validating risk models

This paper presents a new method to validate risk models: the Risk Map. This method jointly accounts for the number and the magnitude of extreme losses and graphically summarizes all information about the performance of a risk model. It relies on the concept of a super exception, which is defined as a situation in which the loss exceeds both the standard Value-at-Risk (VaR) and a VaR defined at an extremely low probability. We then formally test whether the sequences of exceptions and super exceptions are rejected by standard model validation tests. We show that the Risk Map can be used to validate market, credit, operational, or systemic risk estimates (VaR, stressed VaR, expected shortfall, and CoVaR) or to assess the performance of the margin system of a clearing house.
