This paper uses correlation of business cycles to gauge the degree of economic integration of the Chinese provinces. The more integrated the provincial economies are, the stronger their correlations should be. Only the correlations between some provinces in eastern China are found to be...

Life-cycle theory predicts ageing exerting long-term macroeconomic impacts through the reduction of private savings. However, empirical research studying macroeconomic determinants of savings generally regard age dependency as the sole measure of ageing, but overlook longevity, which can also...

Since Rose's (2004) striking finding of negligible WTO trade effects, numerous studies have attempted to solve the so-called WTO puzzle. These studies have progressively improved model specifications to control for potential sources of bias, but they often lead to conflicting results....

"This paper studies investment in health and human capital in a life cycle model. Health investment enhances survival to old age by improving health from its endowed level. The model predicts two distinctive phases of development. When income is low enough, the economy has no health investment...

This paper proposes a data envelopment method to separate avoidable and unavoidable mortality risks. As unavoidable mortality is either beyond the control of humanity or likely to be very cost-ineffective to reduce in the short to medium term, avoidable mortality is of much greater practical...

In a series of papers (Tang, Chin and Rao, 2008; and Tang, Petrie and Rao 2006 & 2007), we have tried to improve on a mortality-based health status indicator, namely age-at-death (AAD), and its associated health inequality indicators that measure the distribution of AAD. The main contribution of...

In recent times there has been a sense that HIV/AIDS control has been attracting a significantly larger portion of donor health funding to the extent that it crowds out funding for other health concerns. Although there is no doubt that HIV/AIDS has absorbed a large share of development...

Income volatility is studied as a component of economic insecurity using recent data from the Cross National Equivalence File (CNEF). Techniques from the inequality literature are applied to longitudinal household incomes and we refer to the results as measurements of income insecurity. Using...

This paper develops a novel, geometric approach to modelling a firm's hierarchical structure. We model the firm''s hierarchy as the sector of a circle, in which the radius represents the height of the hierarchy and the angle of the sector represents the width of the hierarchy. The firm then...
