A new ordered family of Lorenz curves with an application to measuring income inequality and poverty in rural China

The most common data source on income distribution in China is grouped data. When income data is in grouped form, some acceptable Lorenz model is needed to approximate the underlying Lorenz curve. This paper presents a new family of Lorenz curves and applies the main model in our proposed family of Lorenz curves to income data for rural China over the period 1980 to 2006. We find that the income share of the rural population at the low end of the income scale has been shrinking, income inequality in rural China has increased over time and that income inequality has impeded attempts to reduce poverty. However, the welfare of the rural population is still improving in terms of the generalized Lorenz dominance criterion.     

Goodwill—an Example of Puzzle-Solving in Accounting—a Comment

Ma and Hopkins' (1988) paper on accounting for goodwill derives insupportable conclusions because its analysis is based on an inappropriate paradigm. This comment presents a supportable rationale for capitalization and amortization of purchased goodwill and concludes that the 'unsolved puzzle' that Ma and Hopkins present is likely to be a corroborating example for the 'old' matching-based paradigm and a confounding example for the 'new' valuation-based alternative.     

Auditing,Reasoning Systems,Reporting Frameworks,and Accounting Policy Risk: A Response to Alexander

This response to Alexander (2010 ) clarifies the approach taken in Smieliauskas et al. (2008 ). Here we elaborate further on the significance of the accounting risk concept for fairness of presentation in financial reporting. In the process we show how Alexander's potentially important concept of accounting policy risk can be made operational via the concept of accounting risk.     

A Short-Run Employment Function for Australia: 1911–12 to 1938–39

This paper develops a short-run employment function model in which the speed of adjustment is positively related to the level of unemployment. The model is fitted to aggregate Australian data for the period 1911–12 to 1938–39, a period which includes the high unemployment years of the 1930s. Full information maximum-likelihood estimation procedures are used and a log-likelihood ratio test indicates that the variable speed of adjustment model is to be preferred to a fixed adjustment speed model. The speed of adjustment was quite sensitive to the unemployment rate. The policy conclusion of the paper is that if Australian unemployment rates rise to levels that are unprecedented in the post-war period, firms may shake out surplus labour at a surprisingly fast rate.
