宏观统计数据质量规范研究

根据国内外宏观统计数据质量规范演变的历程,在界定宏观统计数据质量新内涵的基础上,依据国际货币基金组织评价数据质量的规范,本文对我国宏观数据质量的规范进行了实证研究。我国宏观数据质量在金融统计数据、社会人口统计数据上与国际货币基金组织制定的数据公布通用系统(GDDS)一致,而财政统计数据与对外经济数据与GDDS尚存在差距;我国数据公布系统在金融统计和人口统计上与GDDS一致,在对外统计与财政统计上与GDDS存在一定差异。     

浅析宏观调控下地产金融的新渠道

纷至沓来的地产融资的新渠道,犹如一场变革前奏,正在激荡着国内地产金融模式的发展之路。在宏观调控下,银行贷款和上市融资这两种主要融资渠道的受制,房企如何解决资金链的问题,未雨绸缪积极开拓多种融资方式、保持领先的市场竞争力,成为房企亟待解决的问题,同时也是金融学术界研究的焦点。本文首先从地产金融的历史沿革展开,通过分析宏观调控政策下地产金融的现状入手,进一步探讨宏观调控对地产融资渠道的影响,最后研究和解决房企目前存在的融资难题,开拓多元化的融资新渠道。     

Effects of scale economies and production seasonality on optimal hub locations: the case of regional fresh produce aggregation

Interest in supporting local and regional food systems is rising and food hubs have attracted considerable attention among Federal, State, and local policymakers. This study explores the problem of endogenous hub location in fresh produce value chains in the Northeastern United States. To overcome limitations in the literature, we incorporate the effects of economies of scale and production seasonality into our models. Three experimental models are designed to examine the effects of alternatively applying yearly, quarterly, and monthly data on model solutions. We explicitly assess how interactions of scale economies and seasonality influence the structure and spatial attributes of an optimal regional produce aggregation hub system. The three models generate marketed different solutions and in many respects they lead to different conclusions about developing local/regional supply chains. The monthly model allows for production seasonality and actual hub operation cycle frequency and thus leads to more efficient hub solution with rich policy implications.     

Economies of traffic density and scale in the integrated air cargo industry: The cost structures of FedEx Express and UPS Airlines

This paper examines the cost structures of the leading integrated air cargo carriers, FedEx Express and UPS Airlines. A total cost model is estimated for the two carriers using quarterly data on domestic operations and costs over a nine-year period (2003–2011). The estimated model indicates that the integrated industry exhibits increasing returns to traffic density and constant returns to scale. Accounting for carrier-specific differences in cost structure and network size, FedEx Express is found to be more cost-efficient than UPS Airlines. Looking at the carriers individually, UPS Airlines exhibits substantial economies of traffic density and constant returns to scale while FedEx Express' cost structure is characterized by weak economies of density and constant returns to scale. The combined effect of returns to density and returns to scale on the cost structures of integrated carriers is captured by economies of size. Both FedEx Express and UPS Airlines exhibit economies of size, indicating that carriers in the integrated industry can be more cost efficient by making appropriate adjustments to their network size as their output grows. Moreover, the relative cost-efficiencies of the carriers are reversed when their network-size differences are not controlled.     

The composite cost function and efficiency in giant Japanese banks

This study provides further empirical investigation, in the context of giant Japanese banks, of the recent claim by Pulley and Braunstein (1992, A composite cost function for multiproduct firms with an application to economies of scope in banking, Review of Economics and Statistics 74, 221–230), that their new composite model for the multiproduct cost function has important advantages over the separable quadratic, generalized translog and standard translog models. In addition to assessing the composite model's relative ability in measuring global scope and scale economies, the study also extends the P-B analysis to assess measurement of product-specific scope and scale economies, pairwise cost complementarities between outputs, changes in the marginal costs of outputs and technological change. The results appear to confirm P-B's chain. The persistent finding of scale economies for large Japanese banks is also investigated and confirmed.     

廉租房建设与国家宏观经济

通过对公建廉租房对宏观经济影响的分析,论证政府在城市化高速发展阶段大规模介入房地产的必要性.同时,提出了政府公建住宅建设需要的其他配套政策.文章认为,中国应当取消经济适用房建设,并把廉租房建设上升为国家战略,一揽子解决高速城市化阶段社会财富再分配、公共秩序建立、劳动力就业、金融泡沫风险等一些战略层面的问题.通过扩大内部需求市场,将国际经济竞争的主战场从国外的"客场"转向国内的"主场".把我国经济的成长更多地建立在自主的基础上,从而掌握更多的经济主权.     

Optimal Size in the Waste Collection Sector

The purpose of this study is to analyze the cost structure of a sample of Italian wastecollection firms in order to assess economies of scale and density and, therefore, definethe optimal size of the firms. A total and a variable translog cost function were estimated using panel data for a sample of 30 firms operating at the provincial level over the period 1991–1995.The empirical evidence suggests that franchised monopoly, rather than side-by-sidecompetition, is the most efficient form of production organization in the waste collection industry. Further, the majority of firms are not operating at optimal scale.     

Motion Pictures Industry: Economies of Scale and Trade

Recent economic theories find industrial structure to be an important determinant of the pattern of trade. In the motion picture industry, economies of scale and imperfect competition, in addition to cultural sovereignty, are conditions sometimes used to justify protectionist policies. This paper examines the significance of the capital-labor ratio, VCRs, market share, tariffs, domestic market size, taste similarities, stars and domestically popular films on international trade in the industry. The results indicate that stars and blockbusters in the domestic market do not seem to influence consumption of films overseas, however, external economies of scale are present in the industry, tariffs are effective trade barriers in the industry, and VCRs increase the chances of piracy.     

Strategies to prevent economic recessions from causing business failure

An average of more than 500,000 businesses failed in the United States during each of the 10 recessions that have occurred since the end of World War II. Yet, scholar and practitioner understanding of how to prepare for and respond to the challenges of an economic downturn remains extremely limited. This article analyzes and synthesizes the information from academic theory and business experience on managing through an economic recession. To assist firms in successfully navigating economic recessions, we suggest a program that involves positioning by investing in multiple markets and geographies, planning by developing a turnaround plan for facing sharply declining sales, promoting by maintaining marketing initiatives, and preparing by acting in anticipation of economic recovery.
