The inflation problem in China has attracted a great deal of international attention in recent years. This paper examines the time series properties of China's CPI series. It is found that the overall inflation series and the inflation of food, tobacco, clothes, urban transport and urban housing...

It is well known that the standard Breusch and Pagan (1980) LM test for cross-equation correlation in a SUR model is not appropriate for testing cross-sectional dependence in panel data models when the number of cross-sectional units (n) is large and the number of time periods (T) is small. In...

While coping with nonsphericality of the disturbances, standard GMM suffers from a blind spot for exploiting the most effective instruments when these are obtained directly from unconditional rather than conditional moment assumptions. For instance, standard GMM counteracts that exogenous...

<b> </b> This paper proposes a test for the null of sphericity in a fixed effects panel data model. It uses the Random Matrix Theory based approach of Ledoit and Wolf to test for the null of sphericity of the error terms in a fixed effects panel model with a large number of cross‐sectional...

There are a number of theoretical reasons why cities interact with each other. Such spatial interdependence has been largely ignored by the empirical literature with only a couple of recent papers accounting for such issues in their estimation. This paper takes spatial dependence panel data...

Nitrogen (N) is essential for crop growth and development under stress. The photosynthetic capacity of crops depends on the leaf N content (Na ), and leaf N allocation is an important factor affecting net photosynthetic rate (Pn ). However, the relationship between N supply and leaf N allocation...
