Affected by many factors, such as investment limits, inflation and interest rate cut, the rate of return on investment is very low. The introduction of the new policy allows the basic pension fund to enter the capital market, which is of great significance to improve the rate of return on investment, ease the pressure of capital gap, and promote the healthy development of the capital market. This paper makes a deep analysis of the rationality of the basic endowment insurance fund entering the market, and then puts forward some suggestions to avoid the risk of the pension market.展开更多

The results show that farmers' risk attitude and credit rationing are in a significant positive correlation. The stronger farmers' risk aversion is,the more serious the demanded credit rationing becomes. Such risk attitude determines the risk cost and risk premium,thus affecting the credit behavior and credit rationing degree. In addition,distance between farmers' residence far the city and their land amount have a positive significant influence on credit rationing,while farmers' education level,income,family labor force have a negative significant effect on credit rationing. Based on these findings,the paper further analyzes the relationship between farmers' credit using and credit rationing as to farmers with different risk attitudes. Measures to relieve the farmer's credit rationing must be taken from government,financial institutions and farmers,respectively.展开更多

Four approaches to setting regulatory limits considered here based on NOELs/LOELs yield the following estimates of the safe levels of perchlorate in water (when perchlorate in water is the sole intake) or total goitrogens (PEC) acting through the same mechanism: 1) Approach 1: 18 μg/L;2) Approach 2: 400 μg/L (50% required inhibition) or 38 μg/L (5% required inhibition);3) Approach 3: 338 μg/L (without serum half-life correction) or 573 μg/L (with serum half-life correction);4) Approach 4: 737 μg/L (without serum half-life correction) or 973 μg/L (with serum half-life correction) for 50% required inhibition;375 μg/L (without half-life) or 735 μg/L (with half-life) for 5% required inhibition. Where water is not the sole route of exposure and perchlorate is not the sole goitrogen acting through the sodium-iodide symporter mechanism, the results of Approaches 3 and 4 can be applied to mixtures of compounds that produce these values as PECs. Results of the analysis suggest that compound-by-compound regulatory limits may be better dealt with through a change to risk-based management strategies that are built around the concept of focusing limited regulatory resources on the main contributors to risks induced by the mechanism considered here.展开更多
