我国发展奖励旅游初探

基于当前我国奖励旅游发展的现状，本文通过分析奖励旅游的内涵、特点，并对我国发展奖励旅游对策进行初步探讨。     

制度在经济绩效中的作用

中央计划经济的绩效与市场经济的绩效有显著性的差异，产权和资源配置方式的差异是决定不同经济体系经济绩效差异最为重要的因素。制度是经济体中经济个体博弈的基本规则。市场经济比中央计划经济提供了更强的激励．从而更有效地减轻了道德风险带来的效率损失，所以从消费者福利来看，市场经济比中央计划经济更有效。在一定的条件下，无论是从产出还是从消费者的福利来看，市场经济都比中央计划经济更有效率。     

具有奖励机制与再保险安排的最优保险合约设计

在保险合约中引入奖励机制可以使投保人动态参与到保险合约中,赋予了投保人在面对索赔事件时是否执行索赔的可选择权,改变了传统保险合约中投保人执行索赔的单一权利,但却增加了保险人潜在的流动性风险。保险合约中再保险的安排则可以对冲由于奖励机制产生的潜在流动性风险,进一步分散保险人的风险,有助于保险人稳健经营。基于此,通过建立具有红利奖励机制与再保险安排的最优保险合约设计模型,最终求解得到最优保险合约是具有最优免赔额形式的保险合约。利用算例研究方法进行建模,研究结果显示,最优保险合约中的最优免赔额与奖励机制中的红利奖励之间具有正向关系,保费、自留额与最优免赔额之间则存在着显著的负向关系。     

平价上网光伏发电项目经济性评价、影响因素及对策

太阳能光伏发电在我国经历了快速的推广应用,虽因享受高额财政补贴而备受争议,但太阳能光伏发电逐步摆脱对财政补贴的依赖,已经达到了平价上网的条件。本文回顾了我国光伏发电上网电价下降的历程,探讨了促进上网电价逐步下降的驱动力。建立以内部收益率(IRR)为平价上网光伏发电项目经济性评价的模型,分析了影响平价上网太阳能光伏发电项目经济性评价的“弃光”严重、非技术成本高企、补贴拖欠等因素,通过算例分析计算了其影响程度,并对解决这些障碍因素从政府和企业两方面提出了对策与建议。     

元代和买法律制度考论

和买,泛指官府向民间购买物品的行为。其核心便是“和”,即蕴含着自愿交易、买卖的官民双方地位平等、官府购买民间物品应以货币的形式支付对价等含义。为了规范和买行为和保障和买秩序,元继于宋,确立起了一整套包括均平摊派、时估、法定程序、和买钱货两清的支付原则、税课管理制度等在内的和买法律制度体系。然而,和买法律制度在“商品化/赋税化”“和/不和”的博弈中,最终滑向了政府主导、赋税化的境地,而随意的摊派与吏治的败坏在其中起到了催化剂的作用。和买法律制度只能在一定程度上起到减缓其由“和”向“不和”的赋税化性质蜕化的作用。     

促进共同富裕的税收制度与政策研究

实现共同富裕是社会主义的根本目标,是社会主义优越性的体现.本文首先介绍了共同富裕的内涵,共同富裕是全体人民的富裕,是兼顾公平与效率的富裕.本文进一步阐述了税收制度在促进共同富裕中发挥的积极作用,并结合具体数据进行国际比较,剖析目前我国税收制度在促进收入分配方面存在的不足.我国税收制度在缩小收入差距方面已取得阶段性成效,但仍存在直接税体系不完善、"税收洼地"引发诸多避税风险、税收征管体制面临多重挑战等方面的不足.最后,本文从持续优化税收营商环境,鼓励勤劳创新致富;健全直接税体系,提高税收调节收入再分配的作用;规范地方税收优惠,维护财政收入分配秩序;提升税收征管水平,严厉打击偷税漏税行为四个维度提出了政策建议.     

Teams, Firms and the Evolution of Profit Seeking Behavior

Even as advances in information theory over the last quarter century have cast increasing doubt on the proposition that firms successfully maximize profits, the objective of profit maximization continues to be an axiomatic feature of the neoclassical theory of the firm. This paper attempts to improve our understanding firms by treating the objective function as an open question. Specifically, an ontogenetic thought experiment is undertaken to address the question of what differentiates production teams from firms by asking why team members would sell their control rights to a principal, thereby transforming the team into a firm. What results is an account of the emergence of the objective of profit seeking. Profit seeking emerges endogenously as a more fit alternative than the objective of value maximization, which is less capable of coping with uncertainty through purposive adaptation.     

The optimal treatment of tax expenditures

This paper analyzes the optimal treatment of tax expenditures. It develops an optimal tax model where individuals derive utility from spending on a “contribution” good such as charitable giving. The contribution good has also a public good effect on all individuals in the economy. The government imposes linear taxes on earnings and on the contribution good so as to maximize welfare. The government may also finance directly the contribution good out of tax revenue. Optimal tax and subsidy rates on earnings and the contribution good are expressed in terms of empirically estimable parameters and the redistributive tastes of the government. The optimal subsidy on the contribution good is increasing in the size of the price elasticity of contributions, the size of the crowding out effect of public contributions on private contributions, and the size of the public good effect of the contribution good. Numerical simulations show that the optimal subsidy on contributions is fairly sensitive to the size of these parameters but that, in most cases, it should be lower than the earnings tax rate.     

Incentive Contract and Weather Risk

We study contracts designed to remunerate a farmer for the production of an ecosystem service with the payment dependent on the results of the farmer’s actions and on weather conditions. Two contracts are proposed: the first takes into account both the results of the farmer’s actions and a weather variable that reflects the actual atmospheric conditions during the life of the contract; the second bases the payment on the results alone incorporating only the average effect of weather. Social welfare is optimal when both the results and the specific atmospheric conditions are taken into account; however, this type of contract may be less acceptable to the farmer due to his perception of the level of risk involved.We thank two referees for valuable comments.     

基于协同平台的高校教师科研绩效评价体系

在研究组织人员行为绩效评价体系的基础上,分析了传统的KPI(key performance indicator)评价方式所面临的主要问题,提出针对高校教师科研绩效进行分类建模,并设计相应的绩效指标、绩效算法及评价体系来解决问题。最后,用某院教职工2015—2019年在协同信息管理平台上的行为数据,检验了该体系的有效性及合理性,并针对基于协同平台的高校教师科研绩效评价体系的结果分析,提出高校科研管理及绩效激励方案。
