试析方略与清代统治者的民族观

清是一个以满洲贵族为主体的统一的多民族的国家,各民族的政治地位是不可能平等的。通过有关方略的研究,可以了解清代统治者的民族观,既有比较开明的一面,但也有民族歧视的言论和观点。     

赫哲族伦理道德初探

赫哲族的伦理道德是赫哲族人民的宝贵精神财富,它在赫哲族人民的精神生活中起着直接的规范性作用。这也表明赫哲族是一个极为讲究伦理道德的民族,其伦理道德既是中华民族传统伦理道德不可分割的组成部分,又具有自身鲜明的特点。赫哲族伦理道德在赫哲族人的生活习俗、民间文学等诸多方面都有十分具体的体现。在社会主义精神文明建设中,对赫哲族伦理道德的特点进行分析,取其精华,弃其糟粕,通过吸收和改造,使赫哲族的传统道德和社会主义道德相统一,是本文研究的主旨。

A Polynomial Optimization Approach to Principal–Agent Problems

This paper presents a new method for the analysis of moral hazard principal–agent problems. The new approach avoids the stringent assumptions on the distribution of outcomes made by the classical first‐order approach and instead only requires the agent's expected utility to be a rational function of the action. This assumption allows for a reformulation of the agent's utility maximization problem as an equivalent system of equations and inequalities. This reformulation in turn transforms the principal's utility maximization problem into a nonlinear program. Under the additional assumptions that the principal's expected utility is a polynomial and the agent's expected utility is rational in the wage, the final nonlinear program can be solved to global optimality. The paper also shows how to first approximate expected utility functions that are not rational by polynomials, so that the polynomial optimization approach can be applied to compute an approximate solution to nonpolynomial problems. Finally, the paper demonstrates that the polynomial optimization approach extends to principal–agent models with multidimensional action sets.     

Sourcing with Deferred Payment and Inspection under Supplier Product Adulteration Risk

We study the deferred payment and inspection mechanisms for mitigating supplier product adulteration, with endogenous procurement decision and general defect discovery process. We first derive the optimal deferred payment contract, which reveals that either entire or partial deferral can arise, depending on the moral hazard severity and the information accumulation rate. Because of the supplier's incentive to adulterate, the optimal procurement quantity under deferred payment generally is smaller than the first‐best quantity. We then investigate the inspection mechanism and characterize the equilibrium. We find that under the inspection mechanism, the optimal procurement quantity is no less than the first best. A comparison between these two mechanisms shows that the deferred payment mechanism generally can outperform the inspection mechanism when either the market size is small or the profit margin is low. However, we find that these two mechanisms can also be complementary, for which we characterize a necessary condition.
