MONEY, OUTPUT AND INFLATION IN CLASSICAL ECONOMICS

‘Of all the constituent parts of the science of PoliticalEconomy none is perhaps so inseparably bound up with the totalityof the general theory as is the theory of money’ (KarlHelfferich, Das Geld, 1903).     

网络经济学视角下的私人货币

货币是一种典型的网络产品。在直接网络外部性作用下,货币的演化具有标准化和统一化的趋势。但是,人们对支付工具的需求是差异化的,货币发行可以给发行者带来多种收益,因此市场上始终存在着私人货币生存的空间。电子私人货币的兴起是技术进步引发的金融创新,它对交易效率的提高是有益的,但私人货币不会威胁到法币的垄断地位。     

货币需求弹性、有效货币供给与货币市场非均衡模型——解析“中国之谜”与长期流动性过剩

中国的流动性过剩相对于其他经济发达国家更为严重,不但是由于产业结构升级和对外开放度上升而导致的过度货币需求,而且是因为不良贷款引发的货币供给有效性减弱。缓解流动性过剩必须从经济转型时期的货币需求弹性、有效货币供给以及货币市场非均衡等多个方面寻找对策。     

FDI、集聚与东道国利益:一个空间经济学的分析框架

基于空间经济学理论探讨外商投资与东道国利益之间的关系,我们可以发现,在短期内,东道国的国民收入主要取决于其国内要素禀赋的存量,与外资流入的多少并无直接联系;在长期内,外商投资也不能在东道国产生累积循环作用,从而不能形成有效的产业关联效应。而在东道国是大国的情形下,它可以运用较大的贸易政策空间对资本的流动实施宏观调控,并成为制造业的集聚中心。     

THE DISTRIBUTION OF MONEY BALANCES AND THE NONNEUTRALITY OF MONEY*

Recent monetary models with explicit microfoundations are made tractable by assuming that agents have access to centralized markets after one round of decentralized trade. Given quasi‐linear preferences, this makes the distribution of money degenerate—which keeps the models simple but precludes the discussion of distributional effects of monetary policy. We generalize these models by assuming two rounds of trade before agents can readjust their money holdings to study a range of new distributional effects analytically. We show that unexpected, symmetric lump‐sum money injections may increase short‐run output and welfare, whereas asymmetric injections may increase long‐run output and welfare.     

内生货币体系下房价波动对货币供求的冲击

在内生货币体系下,房价上涨导致我国内生货币扩张的途径主要有两条:一是基于房地产抵押信贷需求膨胀引致的商业银行内生货币供给的扩张;二是被房价持续上涨及人民币升值预期所吸引的外汇流入导致央行大量基础货币的被动投放。这样会对货币供应量目标有效性带来影响。因此应将房地产市场监测数据列入当前货币供应量调控的参照指标。     

THE DISTRIBUTION OF MONEY AND PRICES IN SEARCH EQUILIBRIUM*

This article considers a search‐theoretic model of monetary exchange. Agents bargain over both the amount of money and the quantity of goods to be exchanged in bilateral meetings, determining endogenously the distributions of money and of prices. I show that money is neutral if changes in the money supply are accomplished via proportional transfers. However, within the class of lump‐sum transfers, an increase of the rate of monetary expansion tends to decrease the dispersion of wealth and prices and to improve welfare when inflation is low; but when inflation is high enough, the opposite effects occur.     

货币供给内生环境下财政对内需的影响研究

本文首先考察了我国货币供给内生的现实环境,并采用ARDL方法对我国经验数据进行实证检验,验证了我国货币供给的内生性问题,表明税收和政府投资是影响货币供给的内生性因素。在此基础上,从货币供给内生的前提出发,本文构建了扩展的内需增长模型,用SVAR方法考察了财政对我国内需增长率的影响。实证结果显示,税收和政府投资增速提高,均会对内需增长率产生负面影响。同时,本文还探讨了货币供给内生环境下财政对内需的影响机制,认为税收和政府投资会影响货币供给,通过新的影响路径对内需产生负面影响。     

POWER SUPPLY EXPANSION AND THE NUCLEAR OPTION IN POLAND

This paper describes the construction of a data set of the Polish power sector for use with the Elfin capacity expansion planning model. Using Elfin, the paper derives four scenarios and some sensitivities for new generating capacity construction plans. These scenarios simulate choices among several generic generating technologies made to achieve the lowest overall net present cost of operating the power system through 2015. Key results include: (i) single-cycle natural gas-fired combustion turbines prove highly attractive for Poland because of its urgent need for peaking capacity, (ii) nuclear power cannot be excluded from consideration for Poland on economic grounds alone, (iii) the effectiveness of conservation to reduce airborne emissions is limited under scenarios in which nuclear generation is adopted, and (iv) the attractiveness of nuclear is shown to be highly sensitive to assumptions on some uncertain inputs, suggesting the need for a more detailed analysis before policy implications can be drawn.
