MANAGING CALIFORNIA's WATER IN THE LONG RUN

Water development in the western states has passed through an "expansive" phase and now is entering an "intensive" phase. Large untapped sources of high-quality fresh water no longer are available. Using current supplies more efficiently and reallocating water among uses will be necessary so as to sustain economic growth. Water conservation, particularly in the agricultural sector, will be an important part of decreasing both the quantity problems and the quality problems that have developed. This paper discusses alternative policies for gaining these benefits.     

KNOWLEDGE AND GROWTH IN THE VERY LONG RUN

This article proposes a theory for the gradual evolution of knowledge diffusion and growth over the very long run. A feedback mechanism between capital accumulation and the ease of knowledge diffusion explains a long epoch of stasis and an epoch of high growth linked by a gradual economic takeoff. The feedback mechanism can explain the Great Divergence, the failure of less developed countries to attract capital from abroad, and the productivity slowdown. An extension toward a two‐region world economy shows robustness of results and other interesting interaction between forerunners and followers of the Industrial Revolution.     

CAPACITY UTILISATION IN THE LONG RUN: SOME FURTHER CONSIDERATIONS

The variability of long-run capacity utilisation has to be consideredas an expression of the determining role played by aggregatedemand in the process of growth. This paper discusses the modelproposed by Serrano in which such a determining role is apparentlyreconciled with the condition of normal utilisation of existingcapacity in the long run. It is shown that Serrano's conclusionslie on the hypothesis of the constancy of the growth rate ofautonomous demand, an assumption which seems to originate froman erroneous interpretation of the property of ‘relativepersistence’ of ‘normal’ magnitudes. The paperargues that if that assumption is abandoned, the autonomy ofaggregate demand necessarily shows itself through the variabilityof capacity utilisation in the long run as well as in the shortrun.     

THE MARKET SELECTS THE WRONG FIRMS IN THE LONG RUN*

We consider the effects of free entry on the market structure and social welfare of an asymmetric Cournot oligopoly. Even if we allow for the existence of different types of firms initially, only one type (in almost all cases) can survive in the long run. Free entry leads an economy to a symmetric equilibrium, in which the excess entry theorem holds. Further, we consider the socially optimal policy for this economy. In cases of either (i) a concave demand (which implies strategic substitutability) or (ii) strategic complementarity (which implies a convex demand), the type of firms that should remain in the market to achieve social optimality does not necessarily coincide with the type of firms that will survive in the long run. The market may select not only the wrong number of firms but also the wrong type of firms in the long run.     

PRODUCTIVITY GROWTH IN LATIN AMERICA OVER THE LONG RUN

The low pace of Latin American productivity growth in recent decades, despite extensive economic reforms, has yet to be understood in a longer‐run context where factors such as demographic changes, structural shifts, and investment levels can be taken fully into account. The OxLAD database provides comparable sectoral output and workforce series over 1900–2000 for the six leading economies in the region for the first time. Our analysis of this new dataset shows that: intersectoral resource reallocation reduced aggregate productivity growth in all three periods; total factor productivity growth was low throughout the century, and even negative in the closing three decades; and thus factor accumulation—investment in fixed capital and skilled labor—was the main source of productivity growth in Latin America during the twentieth century.     

EXCHANGE RATE STABILISATION, LEARNING AND THE TAYLOR PRINCIPLE

The paper explores whether central banks can keep their interest rates independent from given foreign rates, and to what extent interest policies designed to stabilise nominal exchange rate changes can be applied instead of, or in addition to, the traditional interest rate response to inflation gaps. This modification of a Taylor Rule is analysed in a simple macro model with some New Keynesian features. Information is imperfect; agents cannot build rational expectations but try to learn 'true' market relations. Results show that the Taylor Principle can be generalised in an open economy with flexible exchange rates.     

THE LONG RUN PHILLIPS CURVE AND THE GOVERNMENT BUDGET CONSTRAINT

This paper considers the proposition that the long run Phillips Curve is vertical except in special cases. It argues that this proposition cannot be sustained once the implications of the government budget constraint are considered. It is then a matter for government policy choice whether the long run Phillips Curve is vertical or non-vertical, and neither case can be considered more general than the other.     

基于区位角度的城市化与经济发展之间互动关系的实证研究--以浙江省为例

以往的研究中很少突出区位条件对城市化与经济发展之间关系的影响。文章以浙江省“各县市”为样本,运用单位根检验、OLS等方法从区位条件角度对城市化与经济发展之间的互动关系进行了实证研究。结果表明,区位条件影响了经济发展过程,但对城市化则无显著影响。最后对研究的不足之处进行了说明。     

中国核心通胀率与产出缺口经验分析

利用新菲利普斯曲线,本文设定包含通胀与产出的非观测成分模型估计中国的核心通胀率与产出缺口。通过卡尔曼滤波平滑推断程序,季度通胀和产出均被分解为互相独立的趋势成分和周期成分。估计结果表明,二十年来我国的潜在产出变化相对于传统HP滤波结果更为平滑,其近似呈线性增长。这意味着我国产出特征可通过简洁的趋势平稳过程来描述,而Nelson and Plosser(1982)以来普遍采用的单位根过程未必是刻画我国产出的最优模型。核心通胀率推断还表明,1998-2002年间的通货紧缩并非如物价指数下降表现的一样严重。     

新冠肺炎疫情的经济影响分析：长期视角与短期应对

本文从需求和供给两侧分析了此次新冠疫情对我国经济的短期和长期影响。在需求侧,基于理论分析和非典疫情对经济的影响特征,经济总需求会随着此次疫情的结束而在短期内快速得到恢复。但此次疫情也会加大总需求和居民收入增速的下行压力。在供给侧,疫情不仅会降低劳动力资源配置效率,加剧劳动力供需结构矛盾,同时也大幅降低了我国的资本投资,在缺乏有效干预措施下,很可能加剧我国资本投资和经济总体增速的短期下滑趋势。而基于理论分析,相应供给冲击也将对我国长期产出带来增长压力。基于疫情对我国经济需求侧和供给侧的影响分析,2020年要实现全面建成小康社会的经济目标需要实施改革力度更大、更为有效的财政和货币等支持政策。

中国工业化阶段性评价实证研究

1978年以来,中国的工业化加速发展,处于工业化成长阶段,期间受到政府宏观经济调控的影响很大。今后5年内中国工业化仍处于加速发展阶段。2008年前后中国的工业化发展将出现拐点,工业化发展趋势将开始下降。     

中国农村地区间消费结构差异的实证研究

消费结构不仅是消费领域的重要问题,而且也关系到整个国民经济的发展.一定时期内人们消费结构的状况最能反映该时期人民生活质量和水平的高低.以农村居民消费行为作为研究对象,按经济与地域差异将中国农村居民分为东部、中部和西部三个区域,建立农村人均消费支出截面数据建立ELES模型,实证研究当前我国农村居民消费行为的内在规律和基本特征.结果表明:东中西部之间农村居民消费呈现出较大的差异,各区域农村居民的收入弹性、自价格弹性和互价格弹性系数相差较为明显.     

中国对外贸易和FDI相互关系的研究

本文基于1980—2001全国的时间序列数据,对中国对外贸易与FDI 之间的关系进行了格兰杰因果关系检验,并以各省及东中西部三大区域数据作统计描述辅证之。文章得到以下结果:中国对外贸易与 FDI 之间的互补作用远大于替代作用,各省市 FDI 与贸易之间的关系存在着惊人的一致性;FDI与制成品的出口具有双向的因果关系;虽然长期中 FDI 对制成品的进口具有促进作用,但短期中 FDI 对制成品的进口具有替代效应;FDI 对贸易的短期影响具有滞后性,滞后三期的效果最为显著。     

澳门服务产业集聚效应实证分析

把澳门服务产业区位商作为集聚指数纳入生产函数的计量经济学模型中,通过回归分析,测算澳门整体经济和部分服务行业的集聚效应。从研究结果得知,澳门服务产业的区域集聚对整体经济以及博彩业、餐饮业、酒店业产生明显的促进作用,但对银行业、旅行社、运输和仓储三个行业出现负集聚效应,而通信业、批发和零售业、不动产管理业则不能确定集聚经济的存在。     

中国省际资本流动规模实证研究

基于市场交易中资金与货物流向相反的逻辑,以地区货物和服务净流出减去其净出口的相反数来测算中国省际资本流动的规模,并分析其制度成因。结果表明:1980—2008年东部为资本净流入地区,中部为资本净流出地区,而西部则为持续的资本净流出地区;在东部地区内,京津冀为资本净流入地区,长三角和珠三角为资本净流出地区。资本跨地区流动的制度成因在于地方政府行为生成的内生交易费用差异,因而地区产业投资环境建设的重点在于持续降低当地的内生交易费用。在推进区域产业转移和产业升级过程中,可置信的保护产权的承诺等良好的公共治理对于改善地区投资环境必不可少。     

ALL IN: AN EMPIRICAL ANALYSIS OF LEGISLATIVE VOTING ON INTERNET GAMBLING RESTRICTIONS IN THE UNITED STATES

In 2006, the U.S. Congress passed the Unlawful Internet Gambling Enforcement Act (UIGEA) which prohibited financial institutions from processing transactions arising from online gaming activities, thereby severely hindering U.S. residents from participating in online casino games, primarily poker. Enactment of this legislation followed lobbying and political pressure from a variety of interest groups. By examining House roll call votes, we identify empirically the sources of political influence that resulted in passage of the internet gambling legislation. We find that party affiliation was of primary importance, with Republicans more likely to vote in favor of the bill. The percentage of constituents who are Evangelical Christians and also the number of gambling establishments in the district were positively associated with votes for the bill. However, contributions from the gaming industry decreased the probability a congressman would vote for the bill. (JEL D72, L83)     

INSIDER-OUTSIDER EFFECTS IN WAGE FORMATION: AN EMPIRICAL SURVEY*

The paper provides a review of empirical work on insider-outsider and duration effects in wage formation. It presents a theoretical model to investigate the relationship between previous employment and the wage rate. The impact of unemployment and long-term unemployment is considered. Empirical results show that the effect of previous employment on the wage rate is generally insignificant. Both short-term and long-term unemployment appear to have a significant negative impact. Micro-studies reveal that both firm-specific and aggregate variables play a role in wage determination.
