In this paper, we conduct the simple comparative static analysis of the environmental and economic effects of the government and producer services sector's training of rural-urban migrants. We mainly focus our attention on environmental issues and reach the following conclusions: When the...

Standardized means, commonly used in observational studies in epidemiology to adjust for potential confounders, are equal to inverse probability weighted means with inverse weights equal to the empirical propensity scores. More refined standardization corresponds with empirical propensity scores...

The present paper establishes a two-sector general equilibrium model and conduct the comparative static approach to investigate the impact exerted by an increase in the remittance rate of the unskilled migrants on the skilled–unskilled wage inequality in the labor host region. We find that the...

This paper broadens the scope of current theoretical studies, divides rural agriculture into two sectors--advanced and traditional, and takes into consideration the land factor and the urban informal sector. Under the assumption that wages in the advanced agricultural sector are higher than in...

In China, the ecological compensation mechanism (ECM) was initiated in the 1990s solely to address compensation for forest ecological benefits. For nearly 20 years, the ECM has been gradually applied to other areas. This study evaluates the current status, implementation procedures and existing...

In this paper, we divide the labor into skilled and unskilled labor to investigate the impact that the heterogeneous labor movement between sectors has on the environment under the international skilled and unskilled labor flows and the price change of the agricultural products. The main...

Cost effectiveness of CO2 sequestration, especially into aquifers, strongly depends on the sequestration capacities and the routes to connect CO2 sequestration sites and recovery sites. This site dependency of CO2 sequestration makes its evaluation difficult. In order to evaluate the cost...

Japan has started a 5-year national R&D project titled ‘Underground Storage of Carbon Dioxide’ to reduce CO2 emissions into the atmosphere. One of the targets of the project is to select a few preferred storage sites as candidates for large-scale demonstration tests in the next phase, and...

Supercritical CO2 fluid is capable of extracting organic matter from rocks. Although the sealing performance of cap rock is essential for CO2 underground storage, typical cap rock such as shale or mudstone usually contains organic matter. To determine how well cap rocks can seal supercritical...
