H-O国际贸易理论的新兴古典分析--交易效率对国际贸易的影响

赫克歇尔一俄林的生产要素禀赋理论作为主流经济学派理论在国际贸易理论总体系中的影响力是巨大和深远的。而新兴古典贸易理论的发展，为解释国内贸易和国际贸易提供了一个统一的理论内核。这一理论的完美框架和强大的现实解释力引人瞩目。其理论的核心在于该理论独特的分析工具：超边际分析方法。采用新兴古典经济学的超边际分析法，引入交易效率，对赫克歇尔-俄林的生产要素禀赋理论进行新的分析，可以得出很多有价值的结论。     

西方国家劳动力市场灵活化改革的理论分析

灵活化目前已成为西方国家劳动力市场改革的主要发展趋势。西方国家希望通过放弃凯恩斯主义的劳动就业宏观需求管理政策、减少政府和工会对劳动力市场的管制与干预,以及实行激活性劳动就业政策等措施来降低劳动力市场的刚性,提高就业率。从理论上来讲,劳动力市场灵活化改革的根源在于:凯恩斯主义就业政策的失灵、刚性劳动力市场的低效率和全球化时代生产方式与就业模式的根本性变革。同时,劳动力市场的灵活化也被认为是降低失业率的一条有效途径,也是政府、资本和工会之间新的力量平衡下的一种选择。     

经济增长与城乡居民收入——一个实证研究

文章借助VAR模型、协整理论及Granger因果关系检验等分析方法,研究了1985～2004年我国经济增长对居民收入的影响关系。结果表明经济增长与城镇居民收入之间存在显著的长期动态均衡关系,经济增长是城镇居民收入变动的Granger原因;但是经济增长与农村居民收入之间不存在长期均衡关系。经济增长与城乡居民收入的不同关系已发生质的差别。     

唐代寺院的水碾硙经营

唐代佛教寺院经济发展到了兴盛阶段，其经济活动和整个社会生活有着密切的联系。寺院大规模的水碾硙经营活动，对于国家经济和管理制度都产生了重要影响。唐王朝水权管理制度的变迁，在国家制度建设方面有着重要意义，但在实际执行过程中其绩效有限。从佛教寺院水碾硙经营的角度进行考察，表明唐代寺院经济与当时国家制度有着密切的互动关系，而且其影响已逐步深入到社会生活的各个层面。     

Cross-subsidization Due to Inframarginal Support in Agriculture: A General Theory and Empirical Evidence

A general theory of cross-subsidization due to inframarginal support is developed. Two sources of output distortion are identified: exit deterrence and extramarginal output. Some firms would not be in business without the subsidy. Cost savings due to declining average costs are always greater than the losses incurred where price equals marginal cost. Moreover, it is theoretically possible for inframarginal subsidies to expand output more than equivalent fully coupled subsidies. Empirical analysis of U.S. dairy subsidies isolates these components of cross-subsidization and finds distortions from inframarginal support to be substantial, with implications for trade negotiations, dispute settlement, and policy formulation.     

Cost impact of oral capecitabine compared to intravenous taxane-based chemotherapy in first-line metastatic breast cancer

Abstract

Objective: Few studies have examined the costs associated with differing first-line chemotherapy regimens in patients with metastatic breast cancer (MBC). This study compares the relative cost impact of women starting first-line chemotherapy with capecitabine versus taxanes.

Methods: Women receiving first-line chemotherapy for MBC from 1998 to 2002 were identified from a hybrid North Carolina Medicaid-claims-tumour registry linked database and Medicare records, and were followed through to 2005 with claims data. Statistical t- and chi-square tests were used to compare baseline characteristics between patients who received first-line chemotherapy with capecitabine versus taxanes. Projected mean costs for 12 months continuous eligibility were estimated using an ordinary least squares linear regression. Overall cost impact of capecitabine after start of therapy was then examined using a multivariate log-linear regression model.

Results: While patients starting taxanes had significantly lower total costs in the pre-index year than patients starting capecitabine (mean: $20,042 vs. $35,538, p<0.001), in the post-index year, the patients on taxanes experienced significantly higher healthcare utilisation and associated costs compared to patients on capecitabine (mean: $43,353 vs. $35,842, p=0.0089). The differences were primarily attributable to lower expenses in chemotherapy related claims and fewer visit days to outpatient settings for patients on capecitabine. After adjustment with propensity scores and other confounders, the capecitabine group was associated with 32% lower healthcare costs compared to the taxane group (p=0.0001).

Conclusions: In this population-based study, women who received capecitabine as first-line treatment for MBC had significantly lower costs compared to women starting taxane therapy.     

The Dynamics of Self-Esteem and Physical Self: Between Preservation and Adaptation

The aim of this study was to model and characterize the psychologicalprocesses that underlie the dynamics of global self-esteem and physicalself over time. Twice a day for 228 consecutive days, seven participantscompleted a short inventory (PSI-6, Ninot et al., 2001) measuring sixsubjective dimensions: global self-esteem, physical self-worth, physicalcondition, sport competence, physical strength, and attractive body.Each series was modeled by means of ARIMA procedures. The resultsshowed that a simple moving average model provided a satisfactoryaccount for the dynamics of all series. This model suggests that acombination of two opposite processes underlies the dynamics ofself-concept: preservation, which tends to restore the previousvalue after a disturbance, and adaptation, which tends to inflectthe series in the direction of the perturbation.
