效率、公平、社会稳定与住房问题——基于世代模型的政治经济学分析

土地和住房是劳动者历史共同体的公共物品。社会是否能够按照效率与公平的原则解决住房问题,其本质是社会是否能够解决劳动者现实具体利益与历史一般利益的矛盾,即个体理性与国家理性的矛盾。公共权力通过经济制度对租金的抽取和使用是解决住房问题的基本途径,不同制度模式具有等价性。在社会稳定的约束条件下,公共权力对租金的抽取和使用并不必然保证住房问题的解决符合效率与公平的原则,为此社会还需要具备公共权力良好的政治性质、法律约束力以及劳动者对国家理性道德自觉的条件。     

虚假广告治理模式的三方博弈分析

随着我国市场经济的不断完善,广告逐渐成为消费者了解商品的性能、价格与种类的重要途径。但目前虚假广告充斥市场,部分商品经营者通过虚假广告获取超额利润,扰乱市场的正常秩序。本文利用博弈论理论,建立虚假广告主、政府及寻租者的三方博弈模型,对虚假广告的治理模式进行分析,提出了改进虚假广告治理的建议,以期能对完善虚假广告的治理模式有所启示。     

我国公共租赁房的租金定价模型

公租房补充和完善了我国保障性住房制度,但如何制定合理的公租房租金标准,才能促进公租房健康可持续发展显得尤为重要。公租房租金制定应遵循一定的原则,即成本回收、差别定价和可持续性原则。     

地租视角下农村土地承包经营权流转问题研究

针对农村土地承包经营权流转问题的法学研究成果与经济学理论成果相互抵牾的困境,从地租视角揭示农村土地制度演变的内在机理,在对传统地租理论分析的基础上构建一个新的农村土地承包经营权流转地租理论。新地租理论应以农民土地承包经营权有效实现为研究对象,要将制度环境变化作为最重要的实现条件,其核心问题是形成一个完善市场经济体制下的农业用地地租分配体制机制。     

Open access,common property and scarcity rent in fisheries

Open access resources are frequently not managed efficiently, resulting in falling stock levels and a declining income for fishermen. In the late 1970's, the policy response to this problem was the implementation of 200-mile fishing zones, which enabled the European Union to formulate and implement the Common Fisheries Policy, aimed at (among other things) conservation and distribution of available stocks. In Germany, this shift from an open access regime towards a common property regime had favourable outcomes. The trend of falling prices was reversed. The conclusion was that intertemporal efficiency had increased as a result of (inter)governmental policy. Apparently, a wedge was formed between price and marginal harvesting costs, implying that scarcity rent had returned as a component of prices.     

Victim or Victimizer: Firm Responses to Government Corruption

What is the relationship between government corruption and firm performance? To address this question, I conduct a review of articles published in the leading management journals on government‐business interactions pertaining to rent‐seeking activities and integrate findings from the fields of international business, social issues in management, public organization, institutional change, and corporate political activity. I find that while much empirical work corroborates the earlier findings suggesting a corrosive impact of government corruption on firm performance in general, management research also points to the heterogeneous impact of government corruption on individual firm performance, driven by the strategic activities conducted by firms in response to corruption. I propose an integrative model of firm strategy vis‐à‐vis corruption that predicts the activity choice of the firm as predicated by its organizational structure, political resources, industry regulation, and surrounding political and social institutions.     

我国可再生能源发展的经济学分析——基于租金理论视角

在常规能源资源逐步耗竭,生态环境日益恶化的背景下,可再生能源逐步替代常规能源成为大势所趋.但是目前我国可再生能源不仅没有与经济同步发展,甚至出现了常规能源对可再生能源的反替代.试图通过租金理论,分析我国可再生能源发展滞后的经济学原因,从而为我国加快发展可再生能源提出一些有针对性的政策建议.     

腐败与金融包容性国际经验研究

金融包容性是指提高低成本的金融服务的广泛可得性。金融服务普及的深度和广度对国民经济的发展起到了至关重要的作用。而腐败会影响金融包容性,将贫困弱势群体排除在外,客观上形成金融排斥,加重小微企业贷款难、贷款贵等问题,降低金融服务实体经济的能力和质量。本文选取1995—2016年170个国家和地区建立非平衡面板数据模型,经过实证研究发现：腐败会显著降低金融服务的包容性,但会提高金融服务的可得性。并且腐败会通过提高银行贷款利率,增加贷款规模以及提高企业融资难度传导到金融包容性。此外,本文还进行了内生性检验,并按时间、经济发展速度、人口规模和地区划分进行异质性分析。本研究填补了腐败对金融包容性影响机制研究的空白,从而丰富了腐败对金融市场影响的研究,也为普惠金融的发展提供了重要补充。     

Advertising a second-price auction

This study examines a symmetric private-value second-price auction model in which the seller solicits bidders at a cost, sets a reserve price, and receives a payoff which is a convex combination of revenue and welfare. The bidder’s valuations are drawn from a distribution with a decreasing hazard rate and non-decreasing virtual valuations. We find that at equilibrium the seller adopts an advertising policy which minimizes the uncertainty over the number of participants, and sets a reserve price which only depends on the distribution of valuations and the weight on revenue in the objective function. A welfare-maximizing seller is shown to advertise more than a revenue-maximizing seller, and a ceteris paribus increase in the advertising level is proved to increase the expected winner’s rent.     

会计稳健性、经济租金与企业剩余收益

通过实证研究会计稳健性与企业剩余收益的关系,以及会计稳健性与经济租金对企业剩余收益的交互影响,发现会计稳健性与企业的剩余收益显著正相关,而会计稳健性和经济租金对企业剩余收益的交互影响较为复杂,其中：稳健性与研发密度、广告密度对剩余收益有显著的正面影响,但稳健性与企业规模、市场份额、流通股比例和资本密度对剩余收益的交互效应不明显。可见,提高会计稳健性,并不一定能为企业带来额外的经济租金收益。
