A recently developed nested error component model for unbalanced panel data is used to estimate insect damage functions. The model estimates the separate random effects for location and year on the variability of yield loss and has smaller standard errors for the regression coefficient than the...

University of York Beijing Normal University The efficiency of the process of investment in human capital through education is of considerable importance both to the individuals involved and to the wider economy. The paper develops an analytical framework in which issues of the efficiency of...

In this paper we examine price transmission for major agriculture (food) and energy products in China for the years 2004 to 2010. The Error correction model (ECM) and the directed acyclic graphs (DAG) are applied to identify price dynamics among these six variables: rice, wheat, corn, coal,...

Based on carbon emission data of 17 cities in Shandong Province in 2005-2009, this paper analyzes carbon emission economic efficiency. It conducts weight distribution by the Ordered Weighted Averaging (OWA) method, and takes systematic evaluation on carbon emission economic efficiency using...

We estimate the impact of rustication on sent-down cohorts during the decade period of the Cultural Revolution, relying on econometric methods and policy reviewing. The data used from the Chinese Household Income Project (CHIP) for the years 1995 and 2002 show that the average income of...

In recent years China has experienced a substantial increase in rural schooling levels and contemporaneous reforms in rural educational policies, including the nationwide adoption of free nine-year compulsory education, the two exempt and one compensation program, and the school consolidation...

This paper analyzes the changes in public–private sector earnings differentials for local residents in urban China between 2002 and 2007. We find that earnings gaps across ownership sectors decreased during this period and that the convergence trend has been in favor of the private and...

The bank lending channel states that changes in monetary policy cause changes in bank loans thus causing changes in real income. This implies the Federal Reserve can influence real income by controlling the level of intermediated loans. We apply a new method to test for an operative bank lending...

We describe four recently developed panel data estimators for unbalanced and nested data, a common problem for economic and experimental data. We estimate a western corn rootworm damage function with each estimator, including separate parameters for random effects from year, location, and...
