技术性贸易壁垒内涵辨正

进入21世纪以来，技术性贸易壁垒替代反倾销成为我国面临的第一大非关税壁垒。但是对于技术性贸易壁垒，世界贸易组织框架下的相关协议，即《技术性贸易壁垒协议》和《实施卫生和植物卫生措施协议》，并没有做出明确的定义。因此，在分析世贸组织相关协议和判例的基础上，提炼出技术性贸易壁垒的内核，以对技术性贸易壁垒的含义加以澄清并重新认识，对于我国具有重大而深远的意义。

对马克思按分配原则的反思

马克思的劳动价值论不仅是剩余价值的理论基础和分析资本主义分配的理论依据，同时也是马克思设想的社会主义按劳分配的逻辑起点。只是以往我们对按劳分配原则的最本质的含义理解不够透彻。实质上，应该说马克思设想的按劳分配原则最本质的内容包括三点，即在未来的社会主义社会中，个人消费品的分配以劳动量的大小为依据，等量劳动获取等量报酬，承认能力本位。在社会主义市场经济条件下的按劳分配原则，仍然没有偏离这三点本质的含义，但已经有了新的特点和形式。     

EDGAR on the internet: The welfare effects of wider information distribution in an experimental market for risky assets

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None > All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed. The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify analytical welfare predictions of expected utility under different policy choices.

生态经济理论与经济体制改革

经济体制改革的理论基础不仅仅是社会主义市场经济理论,生态经济理论也是其中之一,这是由生态经济理论原则及特点所决定了的。同时,改革的目标是建立社会主义市场经济体制,在新体制的建立过程中,也必须注意实现生态经济协调的几个问题。     

城镇体系等级-规模中心地模型的分形构建及其应用

为了给区域城镇体系规模等级结构研究提供更好的理论依据,文章以中心地理论为基础,借助分形理论构建了一般的城镇等级—规模分布模型。在已知城镇规模分布分维数的条件下,可以计算出在不同的中心地模型中所谓值下,区域城镇体系等级—规模的分布序列,并称其为中心地分布模型。与Zipf公式相比,上述模型不仅更具理论内涵、更接近实际,而且具有横向可比性和纵向预见性,还可以确定区域城镇体系规模分布的中心性值,为城镇体系发展提供更好的导向。最后以陕西省关中平原为例说明了此模型在实际中的应用。     

Accounting for the business cycle: Nominal rigidities, factor heterogeneity, and Austrian capital theory

An Austrian interpretation of the New Keynesian small menu cost model of the business cycle is proposed. Austrian and New Keynesian business cycle theories share the feature that the cycle is generated by rigidities which prevent the economy from adapting instantaneously to changing conditions. Austrian business cycle theory is capital-based, focusing on credit expansion which artificially lowers interest rates and causes an investment boom and unsustainable business expansion. In contrast, the New Keynesian small menu cost model of the business cycle is based on nominal rigidities which prevent markets from clearing. Small menu costs introduce dichotomous behavior, where firms find it locally optimal to avoid instantaneous output price adjustments in the face of the cost, but this local optimum results in economy-wide output and employment fluctuations which are much greater in relative magnitude. The small menu cost model of the business cycle is extended and reinterpreted in light of Austrian business cycle theory with heterogeneous, multiply-specific capital, thus providing a rigorous formalization of the Austrian business cycle. The Austrian interpretation of this New Keynesian model fortuitously addresses several of its shortcomings. JEL classification B53, E12, E23, E32
