Production of Chlorofluorocarbons in Anticipation of the Montreal Protocol

Anticipation of an International Environmental Agreement provides an incentive for countries to change their production behavior prior to negotiations in order to gain a favorable bargaining position. Increased historical production figures at the time of negotiations may influence the magnitude of the baseline from which cutbacks will be specified. In this paper we empirically measure the magnitude of such strategic production behavior in the case of the Montreal Protocol on Substances that Deplete the Ozone Layer of 1987. Due to data limitations we specify a two player Nash–Cournot game between the United States and the rest of the world. We find evidence of asymmetric strategic behavior, which resulted in a net increase of aggregate world chlorofluorocarbon (CFC) production.     

行政垄断、寻租与腐败——转型经济的腐败机理分析

本文试图利用寻租经济学的方法,对中国渐进转型过程中所产生的特有的腐败形式——行政垄断的本质、成因、形式、特征进行了分析;基于现有对转型经济中腐败现象的研究,提出了转型经济中腐败现象的新的分类;并对行政垄断,主要是行业垄断的经济损失规模及租金的耗散等问题进行了初步的研究;最后,回顾了中国反垄断改革的进展,并提出了进一步改革的议程。     

腐败、反腐败和中国县际收入差距

中国经济的快速增长和地区间收入差距紧密相联。虽然目前大部分研究文献都用经济因素来解释这一问题,但文章认为,地方政府的反腐败力度也是影响地方收入水平的重要因素。通过利用中国县级横截面数据以及采用普通最小二乘法,文章发现,反腐败力度越大的县的收入水平越高。利用最近发展起来的夏普里值分解法来量化各个解释变量对收入差距的贡献率,文章还发现,反腐败是解释中国县际收入差距的一个重要因素。     

Trade liberalization, foreign ownership, and the environment in a small open economy

This paper examines the effects of trade liberalization on firm ownership and the environment for a small open economy. It is found that trade liberalization via tariff reductions can result in a dramatic switch in firm ownership from domestic to foreign, coupled with a lower pollution tax.     

Information, trade and incomplete markets

The no-trade result of Milgrom and Stokey, J Econ Theory 26:17–27 (1982), states that if rational traders begin with an ex-ante Pareto optimal allocation then the arrival of information cannot generate trade. This paper allows traders to trade before and after the arrival of information. If there are enough securities to hedge against all payoff relevant risk, then the preinformation-arrival allocation is Pareto optimal and information arrival has no effect. This no-retrade result is the competitive analog of the no-trade result of (1982). However, information generically generates trade when markets are state-contingent incomplete.We thank seminar participants at Cambridge, Carnegie Mellon,Cornell, Essex, London, Maastricht, USC, and York and participants at the 2003 SITE, the 2003 SAET and the Fall 2002 Cornell–Penn State Macro Conference.

Leisure time, savings and trade patterns A two-country growth model

This paper proposes a simple two-country endogenous growth model with endogenous consumption, leisure time and wealth accumulation. The model examines possible causes for the world economic growth and the existence and persistence of trade patterns between countries with different preferceces and human capital under internationally free capital mobility. We show how differences in preferences in consumption, leisure time and wealth between the two countries may affect long-run world economic growth.     

经济、贸易与环境相容关系论说

经济、贸易与环境相容意指经济增长、贸易扩大没有损害环境,其判别标准包括零污染排放或者污染排放零增长、零污染遗留或者污染遗留零增长、环境自净极限等三级标准;其实现的必要条件是环境有益的结构效应和技术效应足以抵消规模效应;其测度指标包括绝对值、变化事和比率等三类指标.经济-环境、贸易-环境两对相容关系的成因不尽相同.     

The core periphery model with asymmetric inter-regional and intra-regional trade costs

We generalize the model of Krugman (J Polit Econ 99(3):483–499, 1991) to allow for asymmetric trade costs between regions and for (asymmetric) trade costs that are internal to the regions. We find that industrial activity, in a region, is enhanced by higher costs of importing and lower costs of exporting (more precisely, by a higher ratio between the two trade costs). This suggests that countries may impose tariffs on imported goods and seek to remove the import tariffs in other countries (unilateral protectionism) in order to foster industrial activity. Industrial activity is also promoted by lower domestic internal trade costs and higher foreign internal trade costs (more precisely, by a lower ratio between the two trade costs).     

新农村建设中的新型经济违纪与腐败及其治理

由于取消农业税后,乡镇发展受到财政资金瓶颈制约,在新农村建设中,各地乡镇政府纷纷将目光投向国家各项政策性专项资金。一种新型的腐败行为——乡镇申报国家支农建设项目资金过程中的寻租逐渐被越来越多的单位和部门以及个人觉察并被广泛利用。本文运用寻租理论和新制度经济学对该新型腐败行为从现象到本质进行了深入的理论分析,并提出了治理对策。     

经济发展中的地方官员行为研究——基于政治晋升、财政分权与腐败的视角

本文同时考虑财政分权、政治晋升和腐败三个因素对地方官员行为的影响,进而构建了理论模型。从中得到的主要结论是,在基本模型中,地方官员对政治晋升的偏好程度越高,则其努力程度越高、腐败程度越低。而财政分权程度越高,官员的努力也越高,但对腐败水平影响却是不确定的。在进一步假设腐败会被惩罚的拓展模型中,基本模型的大部分结论都没有发生太大变化,只是分权程度的对努力的影响也变得不确定了。除此之外,我们进一步研究了,对官员腐败惩罚的力度和对官员腐败的惩罚准确程度的影响,相关命题表明,如果对官员腐败惩罚的越严厉,并且对官员腐败的惩罚越准确,官员努力水平和官员腐败程度都会变低。通过对研究结论的分析,我们还对以往文献的结果进行了重新解释。     

Optimal exporting of exhaustible resources with endogenous trade revenue: The case of a resource-scarce and capital-short economy

This paper discusses a dynamic trade problem of a resource-scarce and capital-short open economy. In this economy, exhaustible resources are traded for foreign capital. Different from previous research on similar topics, the models in this paper allows for endogenous export revenue. The optimal trade behavior of the economy is discussed here. The efficiency conditions for the optimal trading under various assumptions are derived. These conditions correspond to the noted Hotelling rules in a closed economy. Finally, policy implications of the results are presented.     

The impacts of innovations and standards on trade of measurement and testing products: empirical results of Switzerland’s bilateral trade flows with Germany, France and the UK

Nowadays, the impact of the measurement and testing infrastructure on economic performance and trade is theoretically and even politically widely accepted. However, there are no empirical studies on this issue. The purpose of this paper is to elucidate the impact of innovative capacity and technical standards as one important part of the measurement and testing infrastructure on international trade flows and competitiveness. In order to focus on the direct causality between innovative technology and measurement and testing standards and the respective market, the empirical analysis concentrates on the trade of measurement and testing products of a country with a top position in measurement and testing technology. In its empirical analysis of Switzerland’s trade flows with Germany, France and the UK, the paper follows the approach of the pioneering paper of Swann et al. (Economic Journal 106 (1996) 1297), who integrated for the first time technical standards as a technology indicator in the estimation of UK trade performance. The trade flows in measurement and testing products from 1980 until 1995 are explained by both an indicator for innovative capacity and for the degree of standardisation. The first indicator is based on the patent applications at the European patent office. The latter uses the stocks of technical standards in the countries differentiated by their regional scope. Four different trade equations are analysed, besides an export and an import function, the trade balance and the intra-industry trade. The results clearly show that both Switzerland’s innovative capacity and its stocks of standards are able to explain its export performance in the three countries. Secondly, especially the stocks of international standards in Switzerland have a positive impact on imports into Switzerland from the three countries, confirming their positive role for fostering trade in general. Thirdly, Switzerland’s export surplus concerning the three trade partners is positively affected by the stocks of international standards in Switzerland, which seem to be an important factor for international competitiveness. Finally, the results of the intra-industry model underline the common view of the general trade-fostering effect of even national standards in the case of the trade with the three countries.     

The impact of the Soviet trade shock on central and East European economies

The paper examines the significance of what is called the Soviet trade shock on central and East European economies. The analysis involves two steps: first, the terms-of-trade effect of replacing the CMEA trading rules by market rules is estimated, and second, the impact of the loss of export markets in the former Soviet Union is assessed. The results of estimating the terms-of-trade effect for Hungary and Poland show that the income losses in 1990–1991 have not been as substantial as commonly believed (3.5 percent of GDP and 1.0 percent of GDP, respectively). The decomposition of the fall of total Soviet imports in 1991 into three categories, reflecting the impact of domestic recession, reduction of trade with ex-CMEA, and diversion of imports from ex-CMEA to western countries allowed us to estimate the CMEA-induced part of the trade collapse at 36 to 49 percent of the total fall of exports to the Soviet Union by the CEECs (except Romania), with the impact of domestic recession being in all cases stronger than the CMEA dissolution effect. An attempt has also been made to estimate the impact of the Soviet trade shock on GDP levels in CEECs. The results obtained indicate that the collapse of exports to the Soviet Union in 1991 may have been responsible for about one third of the officially reported GDP fall in Czechoslovakia and Poland, and for more than half of the GDP fall in Bulgaria and Hungary, but the impact of the CMEA-induced export fall was much smaller. The impact of the Soviet trade shock on Romania was negligible. The results obtained suggest a smaller impact of the Soviet trade shock on Hungary and Poland, as compared with some other studies. The conclusions should, however, be treated with caution, because of many untested assumptions underlying the analysis.I would like to acknowledge helpful comments received on earlier drafts of the paper by Daniel Gross, Dieter Hesse, Gabor Oblath, and Mica Panic. The views expressed in the paper are, however, my own responsibility.     

Tariffs,trade and unemployment in a disequilibrium model: issues and policies

This paper studies the disequilibrium transition process engaged by increased openness to trade, and the effect of institutions, market behaviors and economic policies on that transition. The issue is analyzed with a simple two country (north and south), two goods model, amended in order to take into account the time dimension of both the production and the decision processes. Investigating the consequences of a tariff decrease by means of numerical simulations, we show to what extent wage and price setting, and the degree of tightness of monetary policy affect the outcome of the disequilibrium process. The main result is that capturing the gains associated with international trade requires market behaviors and economic policies, which are rather different from what is usually prescribed.

Distance measures between free trade and autarky for the world economy

We develop a methodology to determine numerically how globalized the world economy is. We present a global general equilibrium model capturing major OECD economies and a residual rest of world for which alternative metrics of distance between observed, free trade and autarky equilibria can be developed. We use data for 2000 and report a number of distance measures between the 2000 observed trade restricted equilibrium and both free trade and autarky equilibria noting the absence of prior literature on metrics of distance between equilibria. The measures are used to determine the degree to which the world economy is globalized.     

法律环境、政府管制与隐性契约

本文从我国法律环境薄弱的转型制度环境出发,将管制视为法律机制欠缺的衍生机制,从理论上分析了管制权力可能外溢,构成隐性契约。以我国IPO遴选管制权为例,本文认为,证券管制机构在各地区间分配IPO资源时,会考虑各地区上市公司发生丑闻的频率和严重程度。证券管制机构的这一做法,并无明文规定,属于管制权力的外溢效应,这是一种无形的游戏规则,事实上形成了隐性契约。地方政府出于自身理性,会做出履行与否以及履行多少的对策。上述分析得到经验证据的支持。本文为理解转型经济中的政府管制作用、契约形式和投资者保护提供了新的发现和证据。     

Specification choice and robustness in CGE trade policy analysis with imperfect competition

In order to contribute to a more comprehensive understanding of the robustness of the quantitative results of applied trade policy simulations to variations in the assumptions about firm conduct, this article provides a systematic synopsis of alternative formulations of imperfectly competitive supply behaviour in applied general equilibrium trade models and examines the sensitivity of simulated trade policy effects to the specification choice and calibration strategy within a prototype multi-country model. The analysis suggests in particular, that simulation results are generally far more sensitive to numerical specification choices at the calibration stage, than to the prior choice of firm conduct specification.

Spatial welfare economics versus ecological footprint: modeling agglomeration,externalities and trade

A welfare framework for the analysis of the spatial dimensions of sustainability is developed. It covers agglomeration effects, interregional trade, negative environmental externalities, and various land use categories. The model is used to compare rankings of spatial configurations according to evaluations based on social welfare and ecological footprint indicators. Five spatial configurations are considered for this purpose. The exercise is operationalized with the help of a two-region model of the economy, that is, in line with the ‘new economic geography.’ By generating a number of numerical ‘counter-examples,’ it is shown that the footprint method is inconsistent with an approach aimed at maximum social welfare. Unless environmental externalities are such a large problem that they overwhelm all other components of economic well-being, a ‘spatial welfare economic’ approach delivers totally different rankings of alternative land use configurations than the ecological footprint.
