Self‐help in housing and chengzhongcun in China's urbanization

This article focuses on the housing issues of rural migrants arising from urbanization, with particular reference to chengzhongcun, a topic with considerable impact on policymaking. An attempt is made to understand the underlying rationale of self‐help in housing and the important role of chengzhongcun in sheltering rural migrants in the context of China's rural‐urban dichotomy. As demonstrated in this study, chengzhongcun accommodate, with little in the way of government resources and assistance, millions of rural migrants because of their social accessibility and affordability. While not denying their social problems, we argue that chengzhongcun in fact act as an innovative and positive agent to promote urbanization in present day China by housing massive numbers of rural migrants and assimilating them into cities. Current government policies towards chengzhongcun have generated a wide range of interest conflicts and confrontations. The consequences of such conflicts show that the government policies were problematic and unworkable, as they violated basic market principles as well as citizen rights. Policy strategy towards the redevelopment of chengzhongcun must acknowledge their credibility in the Chinese road to urbanization and requires more thoughtful and prudent consideration of migrants' demands for affordable housing.     

Marketing Science and the Ivory Tower

How much has quantitative "marketing science" contributed to the practice of marketing? In my view, not much. In this article, based on extensive consulting experience, it is argued that well-established quantitative techniques like econometric models and diffusion models have produced little of either practical or scientific value. Other quantitative techniques, such as conjoint analysis, have been more useful for marketing decision-makers. But what is needed is a more pluralistic culture, drawing on a range of complementary disciplines.     

Focus: Information Ethics

"The overall goal of information ethics is to integrate information technology and human values in such a way that IT advances and protects human values rather than doing damage to them" (Simon Rogerson). We are pleased to present in this issue five papers from a recent European conference on information ethics edited and introduced by Simon Rogerson, Director of the Centre for Computing and Social Responsibility at De Montfort University, England.
We are also pleased to announce a major new feature of the Review, entitled Business Ethics on the Internet, which will be contributed from time to time by members of the Centre for Computing and Social Responsibility at De Montfort University. This will provide regular up-to-date information and comment on the resources which are becoming increasingly available on the Internet relating to the study of business ethics and the practice of ethical business. It will be launched in our July issue in an article entitled "Business Ethics on the Internet".     

Budget deficits and real interest rates: Updated empirical evidence on causality

Using error-correction model (ECM) estimation, the paper empirically examines the causality relationship between the federal government budget deficit and the ex ante real interest rate yield on high grade long term tax free municipal bonds in the U.S. To clarify this deficit or interest rate relationship, the budget deficit is measured by the primary budget deficit, which excludes net interest payments by the Treasury. In a model that includes federal personal income tax rates and net international capital flows, as well as money supply growth, the ECM estimates strongly suggest a bi-directional relationship between the primary budget deficit and the ex ante real interest rate yield. Budget deficits apparently do matter! William Simon's concerns were justified.The author is indebted to P. A. V. B. Swamy for ideas and helpful suggestions and Will Perry for data assembly and processing.     

On measuring the wealth of nations: the US economy, 1964-2001

This paper examines the methodology of Shaikh and Tonak (Measuringthe Wealth of Nations, 1994) underlying their calculation ofestimates of productive labour in the US economy from 1964 to2001. The focus is not on the results but on the methods thatgenerate them. The paper finds that the compromises made byShaikh and Tonak because of data unavailability are unreliable,and that better approximations are possible. On this latterbasis, the Shaikh and Tonak methodology can be used to providethe labour and wage estimates needed for empirical investigationsin the surplus-based tradition.     

Some Tests of APT Mispricing Using Mimicking Portfolios

Cross-sectional and time-series tests using mimicking portfolios are used to assess the exactness of the APT with(out) a residual market factor. The first factor seems to be sufficient to span the efficient set, whether the model is estimated using (un)conditional variance-covariance matrices that are (un)adjusted for nonsynchronous trading. Although the conditional standard deviations of the mimicking portfolios significantly explain the time-variability of security volatilities, the residuals of the mean equation still exhibit heteroskedasticity. Similar results are obtained for portfolios of CAPM-betaranked securities, and for randomly selected individual securities.
