现阶段我国粮补政策的目标选择机制构建与政策建议

粮食补贴政策是保障粮食安全、提高农民收入的一项重要政策措施。从分析现阶段我国经济发展水平、粮食供求形势入手，依据WTO规则并借鉴国际粮食补贴经验，提出以保障粮食安全为重点、兼顾特定目标群体即种粮农民的收入，应该是现阶段我国粮食补贴政策目标的理性选择，围绕这一目标，提出了以构建直接补贴为核心的粮食补贴机制，并提出确立以中央政府为粮食安全调控主体的宏观调控体系，改革粮食风险基金的筹集办法、强化向中西部粮食主产区倾斜的政策强度等的若干政策建议。

Almost Consistent Estimation of Panel Probit Models with “Small” Fixed Effects

We propose four different GMM estimators that allow almost consistent estimation of the structural parameters of panel probit models with fixed effects for the case of small Tand large N. The moments used are derived for each period from a first order approximation of the mean of the dependent variable conditional on explanatory variables and on the fixed effect. The estimators differ w.r.t. the choice of instruments and whether they use trimming to reduce the bias or not. In a Monte Carlo study, we compare these estimators with pooled probit and conditional logit estimators for different data generating processes. The results show that the proposed estimators outperform these competitors in several situations.     

Intertemporal choice under timing risk: An experimental approach

This paper investigates how individuals evaluate delayed outcomes with risky realization times. Under the discounted expected utility (DEU) model, such evaluations depend only on intertemporal preferences. We obtain several testable hypotheses using the DEU model as a benchmark and test these hypotheses in three experiments. In general, our results show that the DEU model is a poor predictor of intertemporal choice behavior under timing risk. We found that individuals are averse to timing risk and that they evaluate timing lotteries in a rank-dependent fashion. The main driver of timing risk aversion is nothing but probabilistic risk aversion that stems from the nonlinear treatment of probabilities.

Partner Choice and the Differential Retreat From Marriage

The contemporary retreat from marriage in the United States has had a differential impact across socioeconomic and racial groups. Here, 1990 marriage rates and propensities for Virginia, North Carolina, and Wisconsin are analyzed regarding (a) the likelihood that persons in different groups ever marry and (b) patterns of partner choice with respect to race and educational level. Marriage remains strong in most race‐education groups but is substantially lower among Blacks and among those with less than 12 years of education. Patterns of partner choice have shifted to show greater symmetry between the educational levels of brides and grooms. Changes have been modest with regard to the level and pattern of interracial (Black‐White) marriage. Marriage is increasingly a union of equals, but a union chosen more by Whites than by Blacks and more by the well educated than by the poorly educated.

论《呐喊》、《彷徨》中虚无主义思想的复杂性

<呐喊>、<彷徨>在价值取向上存在着相当复杂的循环否定和自我否定现象,其思想体系也相应呈现出一种无序的混乱状态.面对两难选择的思想困境,鲁迅主要采用说谎和遗忘两种方式来应对,从而使<呐喊>、<彷徨>的价值选择处在一种空白、悬置的状态,这是<呐喊>、<彷徨>虚无主义思想产生的内在根源.<呐喊>、<彷徨>中所表现出来的虚无主义思想带有鲁迅本人的个性特征与时代印痕,与社会现实存在着一种同构关系.
