HOW TRADING INSTITUTIONS AFFECT FINANCIAL MARKET PERFORMANCE: SOME LABORATORY EVIDENCE

The effects of trading institutions on market efficiency and trading volume are examined. The trading institutions are computerized versions of continuous double auction and "clearinghouse" markets. Traders are experienced, profit-motivated undergraduates. The traded good is a financial asset whose monetary value is state- and trader type-contingent. Traders possess asymmetric private information on asset value. The results show that clearinghouse markets are as informationally efficient as double auction markets and almost as allocationally efficient; the double auction encourages greater trading volume but the clearinghouse provides greater depth; public orderflow information enhances double auction performance but impairs clearinghouse performance.     

Bad Boys and School Suspensions: Public Policy Implications for Black Males

The focus of this research is the disciplinary policy of school suspension and its effect on black male students. We examined the application of public school suspensions by race and sex in an integrated school district in the southeastern portion of the United States. Data for the study were compiled from oficial records housed in the administrative complex for the entire school district. The suspensions cover one academic year from September of 1983 through June of 1984. During this period of time black males were disproportionately suspended in both the elementary and secondary schools. This finding is consistent with other research noting that black students, and in particular black male students, are disproportionately affected by the various policies of public schools. We then discuss the implications of these findings for black males. Policies which limit educational opportunities for black males increase the probability of their need for welfare services, incarceration in prisons, and commitment to mental hospitals. Our conclusion is that the policy of suspending problem students is not only an effort by elementary and secondary school administrators and faculty to remove bad boys but is also one of several policies which limit educational opportunities for black males.

Value similarity about human resources,competitiveness and social responsibility: A study of organizational and suborganizational differences

This study explored the perception of value similarity between employees and top management. Three types of organizational values were identified including values concerning the use of human resources, the competitiveness of the firm, and the importance of social responsibility. Two organizations and two subpopulations within one organization were examined to determine if differences exist in the way different groups configure their values. The results revealed that the importance of value similarity on the use of human resources was univocal or common to both organizations and subpopulations. In contrast, similarity on competitiveness values and social responsibility values were found to vary and thus operate uniquely for different organizations and subgroups. The implications of these findings for the universality versus uniqueness debate within the culture literature and the future measurement of organizational value constructs are discussed.     

Corporate planning—A systems view

This paper examines the, often disregarded, fact that the very inprecision of language often obscures basic underlying conceptual differences between corporate planning as expressed in theory and in practice. Few of the claims that confusions result both from a lack of explicit definitions and from the lack of differentiation between ‘theories of planning’ and ‘theories in planning’.

The purpose of this paper is to propose such a theory of corporate planning through discussion of the following topics: (1) Problems in concepts of corporate planning; (2) The concept of an approach of corporate planning; (3) Propositions that form the basis of a theory or model of planning, relying heavily on a systems framework; and (4) a proposed corporate planning system.     

Family crisis intervention

Family crisis intervention is based on crisis theory and involves the use of individual crisis intervention techniques with one or more family members starting with the person who initiates the request for help. In addition, the relationship between the crises of the individuals involved is formulated and articulated, including the identification of distinct and common hazards and themes. The usual emphasis with children and young adolescents in crisis is on helping their parents to help them. The paper does, however, treat the issue of direct work with children. As in individual crisis intervention, the treatment contact is limited to six weeks, clients are self-selecting, and the goal is the most adaptive resolution of an immediate problem that is possible given the existing inner and outer resources of the family and its members. This implies that the resolution should not impair the functioning or well-being of any individual family member.
