On the asymptotic normality of some unbiased estimates

Abstract

Let X _m(n) =(X _j , n, ..., X _{j m,n} ) be a subset of observations of a sample X_n = (X_1n X _2n ... , X _nn ). Here the X_jn 'S in Xn are not necessarily independent or identically distributed, and m(n) mayor may not tend to infinity as n tends to infinity. Suppose the joint density function h_n =h_n (x _m (n); θ) of the X _jn 's in Xm(n) is completely specified except the values of the parameters in the parameter vector θ = (θ1 θ2, ... , θ _k ), where θ belongs to a non-degenerate open subset H of the k-dimensional Euclidean space Rk and k?m(n).

Silver fetters? The rise and fall of the Chinese price level 1928–34

We show how the silver standard transmitted world silver price fluctuations into China and made the Chinese price level closely linked to the world silver price. Inflation was transmitted between 1929 and 1931 when the world silver price was falling; while deflation was transmitted during 1932 and 1934 when the world silver price was rising. Using micro-level evidence and counterfactual simulations, we show that the exchange rate was the main shock transmission channel, and silver stocks played an insignificant role.     

Institutional-based antecedents and performance outcomes of internal and external green supply chain management practices

Green supply chain management (GSCM) has been a developing topic for at least a couple of decades. Over this time, significant complexities have been observed in its management. Helping to simplify and understand these complexities is necessary from both a practical and research perspective. Given this situation and to further enhance understanding of the topic and even supply chain management in general, this paper develops and empirically tests a theoretical model on the different types of institutional pressures motivating manufacturing enterprises to pursue green supply chain management (GSCM) practices and commensurate performance outcomes. Using a sample of 396 Chinese manufacturers, path analysis is used to evaluate the many structural links. The statistic results show that institutional pressures have driven the manufacturer adoption of internal GSCM practices which in turn relate to their external GSCM practices adoption. The statistic results also suggest that GSCM practices do not directly affect economic performance, but can improve it indirectly. This research contributes to the literature on institutional theory in corporate environmental practices. The research findings provide useful insights for managers seeking to adopt GSCM practices. The results also provide policy insights for professional organizations, regulators, and legislators to further promote GSCM.
