Redefining Beijing Consensus: ten economic principles

We argue that, owing to the conspicuous failure of Washington Consensus-guided reforms in most parts of the developing world in the 1990s and the outbreak of the current global financial crisis, the Washington Consensus, as a general term of neoliberal free market economic thinking, has been withering. In the meantime, the Chinese economic model has gained wide recognition and praise worldwide. Joshua C. Ramo coined the term ‘Beijing Consensus’ as an alternative approach to economic development for developing nations. There has been hot debate on the notion of a Beijing Consensus. We argue that even though there are some problems in Ramo's original definition of Beijing Consensus, we should not reject this notion altogether. Instead, we should try to come up with better conceptualizations of this term. In this paper, we sum up 10 general principles of the Chinese development model as our new definition of the Beijing Consensus.     

THE EVOLUTION OF THE TERM 'WASHINGTON CONSENSUS'

Abstract.  The term 'Washington Consensus', as Williamson conceived it, was the lowest common denominator of the reforms that he judged 'Washington' could agree were required in Latin America. The term has evolved to denote a different set of policies from those initially conceived. This paper investigates the different versions and interpretations of this controversial term and assesses whether the term itself is suitable and viable or slowly becoming irrelevant and obsolete. Most importantly, the evolution of the term mirrors the evolution of economic thought on economic development for nearly the last two decades.     

Note,advance refunding and municipal bond market efficiency

This study uses the public announcement of an advance refunding to examine the informational efficiency of the secondary market for municipal bonds. The data show that bond yields respond quickly and in the direction predicted. The text discusses methodological considerations and the data sources used in the tests. The results of the study indicate that even for infrequently traded bonds, yields can be expected to reflect fully changes in default risk.     

Product complexity effects on information source preference by retail buyers

This study employed an experimental procedure for examining the effects of product complexity on the importance of various information sources to buyers in retail organizations. In agreement with characteristics of products theories, the results showed that the perceived importance of these information sources was influenced by complexity. Contrary to results of similar studies done in industrial settings, personal selling was not viewed as the most important information source at either of the two levels of product complexity studied. Based on the findings, recommendations for improving marketing theory and practice and for future research on organizational buyer behavior were made.     

Strategic management: The state-of-the-art and beyond

A study of 25 major corporations assesses the state-of-the-art in strategic planning, and explores future prospects for developing a more powerful form of strategic management to cope with the transition to a new economic era. Current planning practices show that large corporations have developed complex strategic information systems, a decision-making process that is inherently organic, and planning operations that embody cybernetic principles. However, the prevailing approach to strategic planning is severely limited because it is based upon an old model of corporate management that has become outmoded: a restricted focus on hard technology leaves critical soft issues unresolved, authoritarian hierarchies produce the typical disadvantages of bureaucracy, and a closed-system orientation isolates the firm from its environment. New approaches to business management seem to be evolving now to overcome these constraints: the frontier of economic progress is shifting to a new form of soft growth, organizational structures are being transformed into entrepreneurial networks, and the institutional role of business is expanding to include its external constituencies. These trends represent key features of a new model of strategic management—the “strategically managed corporation”— that is specifically suited for fostering strategic change.     

A model of the national health service for structural analysis and planning

A model of the NHS linking indicators of “need” and demand for health care services, provision and availability of health care facilities, use made of these facilities and outcome of the care provided through the medium of sets of regression equations is described. Problems of obtaining suitable indicators or measures of these attributes are discussed. The structure of interactions between these facets of the NHS revealed by the model and application of the model to prediction of the impact of policy changes are illustrated.     

Theories of the state and the state of accounting: Economic reductionism and political voluntarism in accounting regulation theory

It has recently been suggested that the inability of the economics-finance literature to say anything definitive about the appropriate form of accounting regulation highlights the need to augment neoclassical economic analysis with sociopolitical considerations. It is argued in this paper that patching up the orthodox theory would be futile; that the flaws are so fundamental as to warrant abandoning neoclassical state theory and embarking on a serious debate about radical theoretical alternatives. Economic reductionism and political voluntarism are shown to be the main flaws in the neoclassical theory, and these deficiencies are primarily responsible for the present theoretical disarray. After a brief overview of radical theories of the state, this paper suggests that replacing—not refurbishing—neoclassical state theory is the most plausible strategy for accounting researchers.
