财政分权、贸易不平衡与区域间资本流动

本文基于经典的宏观经济理论及储蓄与投资相关关系检验法,采用空间面板模型,对中国的财政分权与贸易不平衡对区域间资本流动性的影响及分地区的资本流动性进行了研究.研究发现,在全国层面,财政分权的提高或贸易不平衡度的降低会促进区域间资本流动,在地区层面,环渤海、东南、西北、中部、西南和东北地区内的资本流动性依次减弱.总体上,为提高区域间资本流动性,政府应进一步财政分权,同时着力降低区域的贸易不平衡度.

China׳s information security standardization: Analysis from the perspective of technical barriers to trade principles

There have been many attempts for ICT standardization in China. Among them, this paper deals with information security standards. Although information security is often mentioned regarding China?s ICT standardization, it has been rarely examined per se. While most studies on China?s ICT standardization focus on economic aspects (e.g. increased bargaining power) or the government?s role, this paper draws on legal aspects. We select WAPI and ZUC for case studies, and examine their legal aspects, particularly from the perspective of WTO?s TBT (technical barriers to trade) principles. We have found that China?s standardization strategy becomes international-bound and, in fact, the manner in which the Chinese government handles standardization projects has become refined, flexible, and communicative with foreign stakeholders. We see that the changes are responses to the trade concerns raised by foreign stakeholders in various TBT Committee meetings and bilateral meetings. In addition, the Chinese government appears to become market-oriented even in the field of information security where it previously maintained a rigid stance on the ground of national security. This paper points out that the changes are attributed to growing external pressure from foreign governments and firms as well as to internal efforts toward innovation based on indigenous technology.     

Nonlinear analysis for forecasting currencies: are they useful to the portfolio manager?

The importance of a time-varying specification for both the return and the risk of financial assets is well known. The purpose of this study is to investigate if some of the most recently developed econometric models, combined with technical indicators often used by practitioners, can significantly predict future returns. While most studies have focused on either univariate series or in-sample analyses of a given econometric specification, this study considers a multivariate framework where a US based investor daily reallocates a portfolio of three currencies (Deutschmark, Swiss Franc and Japanese Yen). Series of three years out-of-sample forecasts are analysed in terms of risk and return and it is shown that some of the tested speciications can indeed signiicantly predict future daily returns and correlations over this three-year period.     

Technical efficiency of mainstream airlines and low-cost carriers: New evidence using bootstrap data envelopment analysis truncated regression

Between 2001 and 2005, the US airline industry faced financial turmoil while the European airline industry entered a period of substantive deregulation. Consequently, this opened up opportunities for low-cost carriers to become more competitive in the market. To assess airline performance and identify the sources of efficiency in the immediate aftermath of these events, we employ a bootstrap data envelopment analysis truncated regression approach. The results suggest that at the time the mainstream airlines needed to significantly reorganize and rescale their operations to remain competitive. In the second-stage analysis, the results indicate that private ownership, status as a low-cost carrier, and improvements in weight load contributed to better organizational efficiency.     

Two-machine flow shop scheduling with deteriorating jobs and chain precedence constraints

In this paper we investigate two-machine flow shop scheduling problems with deteriorating jobs and chain precedence constraints. We consider two types of precedence constraints. Under the first type constraints, a successor cannot start on any machine before its predecessor has been completed on the same machine. Under the second one, a successor cannot start on any machine before its predecessor has been completed on all machines. We show that the problem with the first type precedence constraints is polynomially solvable, and the problem with the second type precedence constraints is NP-hard in the strong sense.     

经济学视域下的公共政策分析:批判与反思

当前主流经济理论对公共政策的分析主要是基于其广泛适用的规则和假设,在进行演绎式分析推理过程中,其所使用的抽象效率标准将公平分析几乎完全排除在外,从而使公共政策在很大程度上失去了其应有的价值判断。现实中,社会性个体基于契约理性追求角色意义上的目标及其协调,因此,公共政策首先应考虑的是目标定位与一致认可,这必然要兼顾公平与效率,并全面考虑人类行为的伦理、经济和法律方面,这是人作为一切社会关系的总和的必然产物和要求。政府公共政策及其引导下的集体行动是对个体角色目标的协调一致的表现和结果,因此公共政策只有能够满足诸多个体实现不同的个人目标,才有被认可并得到执行的可能。由此可见,公共政策首先应当有其价值判断,该价值判断建立在共识判断的基础之上。     

Innovation and diffusion of environmental technology: Industrial NOx abatement in Sweden under refunded emission payments

We study the actual process of technical change in the case of NOx abatement from large stationary sources that have been regulated by very forceful policies in Sweden. Considerable progress has been made in lowering aggregate emissions and this paper seeks to disaggregate average industry improvements to study how much of it is due to innovations by first movers, and how much is achieved by adoption and diffusion of technology. We find both factors very important. Innovation has been rapid: the best firms have cut emissions on the order of 70%. In spite of this, reductions have actually been even more rapid for the majority of firms so that the median firms have caught up with best practice. We analyze various characteristics of the technological change observed.

Financing R&D in mature companies: An empirical analysis

We study financing patterns of publicly traded R&D-intensive manufacturing firms in Israel. We further characterize R&D-intensive firms by size, physical capital intensity, and whether they issued stocks in the United States, asking whether these features are associated with particular financing patterns. To address these issues, we present, for the first time, adjusted flow of funds charts that treat R&D expenses as a capital outlay (rather than an operating cost that reduces profits, as standard accounting principles prescribe). We also address the question of how R&D inputs should be measured - using R&D expenses or R&D personnel. We construct both expenditure- and personnel-based R&D measures for each firm in our sample, and investigate to what extent these measures are mutually consistent.
