Protection by international transport charges: Analysis by stage of fabrication

This study employs the effective protection model to evaluate the incidence of ad valorem transport charges (freight factors) on U.S. imports at various stages in the production process, with special emphasis on their impact upon the development of manufacturing activities in LDC's. Freight factors, unlike tariffs, are not found to display a widespread tendency to escalate by fabrication stage, and do not appear to bear more heavily on products of major export interest to LDC's than on U.S. imports from industrial nations. Results suggest forces other than transport charges are primarily responsible for inhibiting the growth of manufacturing export industries in LDC's.     

Rational expectations and monetary models of exchange rate determination: An empirical examination

One asset model of exchange rate determination that has received substantial attention in the literature is the monetary model. As with other asset models, expectations of future exchange rates play a key role. Usually these expectations are assumed to be formed rationally. However, to date there has been no attempt to empirically estimate a complete monetary model with rational expectations. In this paper, such a model is estimated and the restrictions implicity imposed by the rational expectation hypothesis tested. The results suggest that both the parameter constraints associated with the monetary model and those implied by the REH are consistent with recent exchange rate behavior.     

The accounting of interpretations and the interpretation of accounts: The communicative function of “the language of business”

The objectivistic philosophical assumptions which underlie contemporary research in accountancy, as well as economics and elsewhere, are challenged and an interpretive alternative is proposed. A “hermeneutical” view of decision-making is examined, first with regard to science in general, and then concerning the human sciences in particular, and finally with regard to economics. Human decisions are not seen as objective, mechanical or behavioristic but as meaningful utterances of minds, as part of a bidirectional communicative process. That is, scientific decisions, like everyday decisions, are mutually interpretive processes of communication in language. Although it is true that much of mainstream neoclassical economics is incompatible with this interpretive approach, the “Austrian” school can be seen as an interpretive version of neoclassicism. This school of economics indicates a way to understand the communicative function the accounting “language” itself serves in the economic process. The professional judgments made by both accounting researchers and practicing accountants, then, are treated as “matters of interpretation,” but as not, thereby, arbitrary.     

Marketing and the law

Marketing decisions are particularly vulnerable to legal rulings made in both the courts and the legislatures. The effective management of those legal implications challenges the modern marketing professional. Grasping marketing’s overall legal environment, including its governing case law, regulatory statutes and future trends, is essential. This review will provide analysis of recent court cases and legislation with particular emphasis on creatively assisting the marketer’s management of the legal factor.     

Emerging patterns of complex technological innovation

Technological innovation is increasingly concerned with complex products and processes. The trend toward greater complexity is suggested by the fact that in 1970 complex technologies comprised 43% of the 30 most valuable world goods exports, but by 1996 complex technologies represented 84% of those goods. These technologies are innovated by self-organizing networks. Networks are those linked organizations that create, acquire, and integrate the diverse knowledge and skills required to innovate complex technologies. Accessing tacit knowledge (i.e., experienced-based, unwritten know-how) and integrating it with codified knowledge is a particular strength of many networks. Self-organization refers to the capacity networks have for reordering themselves into more complex structures (e.g., replacing individual managers with management teams), and for using more complex processes (e.g., evolving strategies) without centralized, detailed managerial guidance. Case studies of the innovation pathways traced by six complex technologies indicate that innovations can be grouped into three quite distinct patterns. Transformation: the launching of a new trajectory by a new coevolving network and technology. Normal: the coevolution of an established network and technology along an established trajectory. Transition: the coevolutionary movement to a new trajectory by an established network and technology. Policy makers and managers face the greatest challenge during those periods of movement from one innovation trajectory to another. These are periods of turbulence; they are the embodiment of Schumpeter's “gales of creative destruction.” This paper investigates how, in six case studies, core capabilities, complementary assets, organizational learning, path dependencies, and the selection environment varied among the innovation patterns. The paper builds on work reported in a recent book by the authors entitled: The Complexity Challenge: Technological Innovation for the 21st Century, Pinter, London, 1999.     

Racial diversity and academic test scores in public elementary schools

This article examines the effect of racial diversity on academic achievement using panel data on San Francisco’s public elementary schools from 2003 to 2007. Theories argue that the relationship between racial diversity and academic achievement may be positive or negative. Few studies have examined the effect of racial diversity in US elementary schools. Fixed effects models are used to examine the relationship between racial diversity and academic performance in elementary schools. Controls for student differences and teaching staff differences are added as part of the education production function literature. Results show that racial diversity has little effect on academic achievement scores.
