Welfare Rigidity,the Composition of Public Expenditure and the Welfare Trap

Welfare expenditure is characterized by rigidity, i.e., it goes up easily but is very hard to get down. We introduced welfare rigidity into an endogenous growth model that includes government expenditure to analyze the impact of welfare rigidity and the composition of public expenditure on economic growth and family utility. Our findings show that welfare spending and economic growth have a non-monotonic relationship that is negative or inverted U-shaped depending on cross-country differences. Higher welfare rigidity reduces long-term economic growth and household utility. According to the estimated optimal size of welfare expenditure, China, as a developing country with a large population, has to do all it can to improve people’s livelihood but must at the same time weigh its limited resources so that its welfare expenditure does not fall into a “welfare trap.”     

Risk minimization for an insurer with investment and reinsurance via g-expectation

Abstract

This paper is devoted to the study of a risk-based optimal investment and proportional reinsurance problem. The surplus process of the insurer and the risky asset process in the financial market are assumed to be general jump-diffusion processes. We use a convex risk measure generated by g-expectation to describe the risk of the terminal wealth with investment and reinsurance. Under the aim of minimizing the risk, the problem is solved by using techniques of stochastic maximum principles. Two interesting special cases are studied and the explicit expressions for optimal strategies and corresponding minimal risks are derived.

"两个口号"论争与俄苏文学文论传播中的期刊

"两个口号"的论争与俄苏文学和文论在中国的传播有关,而这又受制于论争参与者的价值观念与期刊对俄苏文学和文论译介的互动。1934年至1936年,国民党系统的期刊译介俄苏文艺,一般以作品为主,且与"民族主义文艺运动"的主题相关。同人期刊译介俄罗斯文学名家名作,也积极译介无产阶级文学和苏联文艺动态。左翼的期刊译介了大量有关"社会主义现实主义创作方法"和苏联文艺政策的文章。它表明中国的文艺界进一步向苏联的文艺思想看齐,因而"两个口号"论争的理性色彩也进一步加强,但同时也使论争中的"宗派主义"和"关门主义"现象无法完全克服。
