保障功能分化：中国共产党对职业福利的认知与实践逻辑

职业福利是社会保障体系的重要组成部分,中国共产党在综合判断社会、经济发展阶段性特征以及基本社会保障体系构建完成度和保障水平的基础上,对职业福利的认知与实践沿着保障功能分化的逻辑,阶段性、多维度地推进和深化。从建党到计划经济时期,中国共产党将职业福利与公共福利混合为一体来推进,之后在市场经济条件下实现了两者保障功能定位的分化并明确了职业福利的补充保障功能;进而在基本社会保障制度构建完成的基础上,推动职业福利保障功能从微弱补充到实质补充的层次分化;同时协调推进公私部门间的职业保障功能分化进程,从公私分立到公私“可比较”。最终通过对职业保障功能分化的推进,建构起更加可持续的社会保障体系,满足人民对美好生活的需要。     

劳动力流动与中国农村居民消费结构——基于LAIDS模型的实证研究

使用1992~2011年的时间序列数据,采用线性几乎理想需求系统模型(LAIDS),重点检验了劳动力流动对农村居民消费结构的影响。研究发现,劳动力流动会使衣着、文教娱乐及服务、医疗消费有所增加,会减少食品、居住消费,对家用几乎没有影响。为此,应增加工资性收入,完善劳动力流动政策和供给结构。     

Trade Openness and Exchange Rate Regimes

The paper evaluates the net welfare gains of inflation targeting over a fixed exchange rate as a function of a country's trade openness, using a multisectoral structural model calibrated to Chile. For most calibrations with separable preferences, net welfare gains are increasing in trade openness. The reason is that in more open economies terms of trade shocks, which favor inflation targeting, become quantitatively more important, while price markup shocks in the imperfectly competitive nontradables sector, which favor exchange rate targeting, become less important. The most important exception is heavily indebted countries, where net welfare gains are decreasing in trade openness.     

开化县生态公益林建设现状与发展对策分析

基于浙江省集体林区开化县林业局访谈资料,在分析和评价其生态公益林建设现状的基础上,得出其存在森林资源利用不足,林下经济单一,管护体系不健全、公益林调整困难等问题。从主导措施和配套措施角度提出加快生态性城镇建设,利用RS和GIS技术区划边界、健全保障制度、探索发展林下经济等保护和经营管理对策。     

财政支出对居民消费的实证分析

自20世纪90年代中后期以来,我国居民消费率一直低于世界平均水平并且徘徊在百分之三十几的低位。因此,财政支出对居民消费影响的研究,不仅是一个重要的理论问题,更是一个关系到经济平稳增长,提高人民生活水平的现实问题。从20世纪70年代至今,经济学家对财政支出和居民消费的关系进行了大量的理论与实证研究。文章将采用2007-2011年的省级面板数据,应用实证方法分析财政支出对居民消费的影响,研究结果表明：近年来财政支出对居民消费主要是挤入效应。     

Basic income in the United States: Redefining citizenship in the liberal state

This paper examines citizenship-based arguments for work-conditioned welfare and basic income. I argue that the most common citizenship-based justifications for work requirements—the paternalistic and civic republican arguments—are flawed because of their selectivity, and that the only defensible citizenship-based justification for work requirements is the socialist model, which enforces work requirements universally on all. I offer as a liberal alternative a radically pluralist notion of citizenship, with a kind of universal economic suffrage at its core, to justify an unconditional basic income in the US.     

INEQUALITY COMPARISONS IN A MULTI‐PERIOD FRAMEWORK: THE ROLE OF ALTERNATIVE WELFARE METRICS

This paper considers the use of alternative welfare metrics in evaluations of income inequality in a multi‐period context. Using Norwegian longitudinal income data, it is found, as in many studies, that inequality is lower when each individual's annual average income is used as welfare metric, compared with the use of a single‐period accounting framework. However, this result does not necessarily hold when aversion to income fluctuations is introduced. Furthermore, when actual incomes are replaced by expected incomes (conditional on an initial period), using a model of income dynamics, higher values of inequality over longer periods are typically found, although comparisons depend on inequality and variability aversion parameters. The results are strongly influenced by the observed high degree of systematic regression toward the (geometric) mean, combined with a large extent of individual unexpected effects.     

The Long-Run Effect of a Tax-Rebate Program

In each period of a dynamic tax-rebate program, a (fixed) quantity tax is imposed on each unit of a given good, and the tax revenue is rebated back to the consumer in the next period. The program lasts for infinite number of periods. The author considers a representative consumer's dynamic consumption behavior, the long-run steady-state consumption, and the consumer's welfare. Under the standard continuity and strict convexity assumptions on the consumer's preferences, he shows that the tax strictly reduces the consumption of the good in each period as well as in the steady state, and the consumer is strictly worse off. He also provides numerical analysis when the consumer has the quasilinear or the Cobb-Douglas utility functions.     

The Welfare Economics of a Biofuel Tax Credit and the Interaction Effects with Price Contingent Farm Subsidies

A framework is developed to analyze the effects of a biofuel consumer tax exemption and the interaction effects with a price contingent farm subsidy. Ethanol prices rise above the gasoline price by the amount of the tax credit. Corn farmers gain directly while gasoline consumers only gain from any reduction in world oil prices due to the extra ethanol production. Domestic oil producers lose. Historically, the intercept of the ethanol supply curve is above the gasoline price. Hence, part of the tax credit is redundant and represents "rectangular" deadweight costs that dwarf triangular deadweight cost measures of traditional farm subsidies.
