中国固定资产投资的金融驱动力实证研究

通过使用面板数据的建模分析技术,研究了中国区域固定资产投资与金融机构存贷款量之间的关系。研究发现,金融机构是推动本地区固定资产投资增长的重要因素,但是受到政府的区域发展战略规划、地方行政性因素、非公有制经济信贷约束等诸多因素,从而金融机构对于投资的正向推动力度出现了由东向西依次递增的特殊现象。     

A dynamic quality ladder model with entry and exit: Exploring the equilibrium correspondence using the homotopy method

This paper explores the equilibrium correspondence of a dynamic quality ladder model with entry and exit using the homotopy method. This method is ideally suited for systematically investigating the economic phenomena that arise as one moves through the parameter space and is especially useful in games that have multiple equilibria. We briefly discuss the theory of the homotopy method and its application to dynamic stochastic games. We then present three main findings: First, the more costly and/or less beneficial it is to achieve or maintain a given quality level, the more a leader invests in striving to induce the follower to give up; the more quickly the follower does so; and the more asymmetric is the industry structure that arises. Second, the possibility of entry and exit gives rise to predatory and limit investment. Third, we illustrate and discuss the multiple equilibria that arise in the quality ladder model, highlighting the presence of entry and exit as a source of multiplicity.     

Marketing and politics: Models, behavior, and policy implications

The American presidential election is one of the largest, most expensive, and most comprehensive marketing efforts. Despite this fact, marketing scholars have largely ignored this campaign, as well as thousands of others for congresspersons, senators, and governors. This article describes the growth of interest in research issues related to political marketing. This emerging research area lies at the crossroads of marketing and political science, but these fields have developed largely independent of one another with little cross-fertilization of ideas. We discuss recent theoretical, empirical, and behavioral work on political campaigns, integrating perspectives from marketing and political science. Our focus is on (1) the extent to which paradigms used in goods and services marketing carry over to the institutional setting of political campaigns, (2) what changes are necessary in models and methodology to understand issues in political marketing and voter behavior, and (3) how the special setting of politics may help us gain a better understanding of certain topics central to marketing such as advertising, branding, and social networks.     

Skill Formation,Immigration and European Integration: The Politics of the UK Growth Model

ABSTRACT

While a reluctant European player now heading for the Exit, the UK was also an enthusiastic adopter of several key EU economic policies – namely, the skills and technology policies of Agenda 2020 and labour mobility. These initiatives worked with existing British policy, and structural biases, to exacerbate the already bifurcated structure of UK capitalism – between the high-paid technology and financial services sector on the one hand, and low-cost, low-wage sectors on the other hand. In particular, and central to the argument of this paper, immigration from Eastern and Central Europe after 2004 helped to sustain low-cost manufacturing and services industries by undermining firms’ incentives to invest in training. This combined with endemic failures in the UK’s skills system, which is heavily geared towards producing graduates with general skills but neglects the needs of mid and lower segments of the labour market. EU integration, therefore, exacerbated cleavages over skills between high- and low-productivity sectors and may have contributed to social divisions that led to Brexit.     

ON ERROR CORRECTION MODELS: SPECIFICATION, INTERPRETATION, ESTIMATION

Abstract. Error Correction Models (ECMs) have proved a popular organising principle in applied econometrics, despite the lack of consensus as to exactly what constitutes their defining characteristic, and the rather limited role that has been given to economic theory by their proponents. This paper uses a historical survey of the evolution of ECMs to explain the alternative specifications and interpretations and proceeds to examine their implications for estimation. The various approaches are illustrated for wage equations by application to UK labour market data 1855–1987. We demonstrate that error correction models impose strong and testable non-linear restrictions on dynamic econometric equations, and that they do not obviate the need for modelling the process of expectations formation. With the exception of a few special cases, both the non-linear restrictions and the modelling of expectations have been ignored by those who have treated ECMs as merely reparameterisations of dynamic linear regression models or vector autoregressions.     

Cereal marketing liberalization in Tanzania

There is considerable evidence that cereal market liberalization in Tanzania has been a success in spite of poor roads, shortage of capital and vehicles, and lack of market infrastructure and standardized measures. The legal status of the private sector is unclear, however, and public sector policies still favour a heavy official involvement in the marketing system. Farm-gate prices for maize fall off rapidly as one moves away from the primary marketing centres, but on-farm storage of maize poses farmers no insuperable difficulties. Successful implementation of liberalization calls for clarity and consistency in government policy, the reform of financial services, the sale of unused storage capacity to the private sector, the more active involvement of farmers in the liberalized system, the strengthening of extension services, and a policy for regulating interannual price variations.     

Arms production as a form of import-substituting industrialization: The Turkish case

There has been a trend towards increased Third World arms production since the 1960s and by the beginning of the 1980s some 46 developing countries were producing or planning to produce weapons domestically. This paper examines the arguments for indigenous Third World arms production in the context of the Turkish case. The evidence indicates that arms production will be inefficient, expensive and unreliable with limited export potential. The manufacturing base in Turkey is too weak to provide essential components, which will need to be imported, and licensed production will ensure technological dependence is maintained. Employment and backward linkages will be small and, given scarce resources, development will be affected adversely.     

The world economic crisis and the children: A United States case study

This is a review of the United States experience with issues of child health and services, as they relate to changes in economic trends. No existing data systems are entirely adequate for reporting on the current health status of children, an important consideration for the monitoring of children's health in the United States is the focus on subgroups such as those who are disadvantaged for reasons of poverty, discrimination or geographic isolation. Ample evidence exists that children living in poverty suffer adverse health consequences and that the proportion of children living in poverty in the United States has increased steadily since 1975 and dramatically since 1981. Most measures of health status and health risks for children show steady improvements througout the 1970s. The exercise of public responsibility for financing and providing essential services and supports held constant or improved during this recession period, especially during the recession of 1974–1975. The health status and risks for children since 1981 appear to be adversely affected which must be attributed to a combination of circumstances that include serious recession, increased poverty rates for households with children and diminished health benefits and social support services. These findings suggest that when either local or widespread economic reversals are anticipated, health services and social supports for children need to be expanded rather than contracted.
