Mortgage product diversity: responding to consumer demand or protecting lender profit? An asymmetric panel analysis

This article explores determinants of mortgage product diversity for owner-occupied and investment loans in the Australian housing mortgage market. From 2001 to 2012, 65 lenders introduced 1220 mortgage products in Australia. We examine whether the product proliferation was a result of consumer demand or a response to pressure to lower lending rates. We find that consumer demand for mortgages does not have a significant relationship with the number of mortgage products, but that decreases in the policy interest rate are highly significant as an explanatory variable for product proliferation. Such behaviour is consistent with information obfuscation, reducing the ease with which consumers can compare lending rates. Further, the relationship between mortgage products offered and the policy interest rate is asymmetric: decreases in the cash rate are associated with increased mortgage products offered, but increases in the cash rate have a more muted effect on decreasing the number of products.     

Multiple product qualities in monopoly: Sailing the RMS Titanic into the economics classroom

In this pedagogical contribution the authors extend the traditional three-class tariff employed in the French passenger railway system with the more resonant story of the service quality variations associated with the three passenger classes of the ill-fated RMS Titanic. In doing so, they provide economics instructors with an opportunity to integrate the well-known motion picture Titanic (Cameron and Landau 1997 Cameron, J., and J. Landau. 1997. Titanic. Los Angeles: 20th Century Fox, Paramount Pictures, and Lightstorm Entertainment. [Google Scholar]) into the teaching of economics. This article provides instructors with resources that can be used to link historical and modern travel examples of price discrimination in order for students to reach a “deeper understanding of course concepts” (Salemi 2002 Salemi, M. K. 2002. An illustrated case for active learning. Southern Economic Journal 68 (3): 721–31.[Crossref], [Web of Science ®] , [Google Scholar], 725).     

Occupational Segregation and Gender Wage Differentials: Evidence from Malaysia

In Malaysia, the participation of women in the labor market has increased over time. However, occupational segregation and wage differentials continue to be prevalent between men and women in the labor market. The present paper investigates gender‐related occupational segregation and wage differentials based on data collected from 7135 working households in Peninsular Malaysia in 2011. The wage decomposition model introduced by Brown et al. (1980) is used to examine the determinants of gender‐related wage differentials. The results suggest that differences within occupations account for the largest portion of the wage gap between men and women. The results also indicate that wage discrimination within occupations plays an important role in the gender wage gap, while sample selection bias plays an important role in the examination of gender wage gaps.     

The effect of legal status on immigrant wages and occupational skills

Native and foreign-born workers with a high school degree or less education work in different types of occupations. This article exploits the 1986 Immigration Reform and Control Act to examine whether legal status causes immigrants to work in occupations that use skills similar to those of natives. Legal status decreases the manual skill intensity of immigrants’ occupations by about two percentiles. It increases communication skill intensity by a similar amount. This reduces the skill gap between Mexican-born and native-born American workers by 11–15%.     

职业能力的构成研究

培养什么样的人才,决定着人才的能力构成。本项研究通过严格地培训访谈员,精心制订"调查表",采取重点访谈的方式,获得岗位能力构成的基本信息。对所采集的信息,针对每一岗位所要求的各种综合能力及相应专项技能进行分析和归类,形成DACUM表。在分析归纳通用能力过程中,发现工科和商科的通用能力存在着差异,对工科、商科归纳出各自的通用能力。     

产业专用化行为及其激励研究——来自中国证券审计市场的检验

本文从产业组织的视角,研究了中国证券审计市场上会计师事务所的产业专用化行为及其投资激励。我们发现,仅仅在5个二位数行业代码的产业中,一些事务所具有产业专用化行为和行业专家才能。进一步对产业专用化行为的激励研究表明,那些具有行业专家才能的行业领导者通过产业专用化行为实行了差异化的市场策略,收取了更高的审计费溢价。但是非行业领导者通过产业专用化行为实现了规模经济,并将这种成本节约与客户分享以提高其市场份额。因此,会计师事务所的产业专用化行为的激励取决于其实施的市场策略。     

Predicting IJVs＇ effectiveness based on their autonomy levels and the characteristics of their parent companies

Separate research streams have identified relationships between IJV autonomy and IJV effectiveness, and between functional/dysfunctional parent-company differentiation and IJV effectiveness. This study attempts to integrate these two literature streams by examining how these two sets of independent variables interact in terms of predicting IJV effectiveness. Results partially support our hypotheses that the autonomy-effectiveness relationship is less positive with greater functional differentiation and more positive with greater dysfunctional differentiation. The results provide strong support for our hypotheses that activities closer to the local operating environment will influence these relationships such that autonomy becomes more important to effectiveness when an activity has strong local ties.     

Areal differentiation of virtual water for agricultural products and its effect on regional agricultural structure adjustment in China： 1995-2007

With a vast territory, the space-time distribution of water resources is uneven in China. There is a great dif ference in natural conditions and farmland management of agricuttural production in different regions. The areal differentiation of agricultural products virtual water is obvious. Comparison with the agricultural products virtual water from 1995 to 2007 in China shows an increase in the first ten vears and a little decrease in recent years. There has been a tendency of increase all the time in Northeast and Northwest. but a decrease after an increase firstly in other regions. The virtual water offood crops is the maximum which accounts for more than 70% in China. and that of vegetables is in a fast growth. The proportion of agricultural products virtual water to the total water resources in each region has a large difference, showing the imbalance of agricultural water in different regions, which accounts for 50%-90% in Northeast, and 125%-185% in North China. Under the guidance of virtual water strategy, based on the differences of resource endowment, each region should adjust agricultural structure, decide production by water, and select water suitable crops. In water-rich region, agricultural produets of high water consumption should be planted appropriately, which will make full use of the abundant local water resources. In water-shortage region the crop production of high water consumption and low efficiency should be depressed, and that of low water consumption and high efficiency should be supported and increased. It will achieve reasonable disposition of water resources, promote ecological restoration and environmental protection, as welt as ensure food security.     

人力资本、政府管制与中国大城市二元劳动力市场职业配置——以上海市卢湾区为例

中国大城市劳动力市场已经演变成具有"二元"特征的劳动力市场,其中本地劳动力和外来劳动力的职业构成差异不能仅仅用劳动者自身的人力资本来解释,它还与城市政府的选择性管制有关。虽然中央政府已经逐渐取消针对外来劳动力的歧视性限制,但地方政府借助户籍制度实行的隐性、间接管制在城市劳动力市场职业配置中仍然起着重要作用,是外来劳动力在职业选择中处于不利地位的重要原因。     

中医辨证配合化疗治疗晚期肺癌临床分析

目的探究中医辨证配合化疗对晚期肺癌患者的临床治疗效果。方法将我院2011年1月～2012年1月接诊的53例晚期肺癌患者作为研究对象,随机分为研究组与对照组。对照组患者单纯采用化疗治疗,研究组则在对照组的基础上配合中医辨证治疗。对两组病患的治疗效果进行总结与对比。结果研究组治疗前平均分为58.45分,治疗后为71.35分,对照组治疗前平均分为58.13分,治疗后为49.63分;研究组27例患者半年的生存率为81.48%,一年的生存率为48.15%,对照组26例患者半年生存率为46.15%,一年生存率为15.38%;治疗效果上,研究组总有效率为40.74%,对照组总有效率为15.38%。结论对于晚期肺癌患者而言,采用中医辨证配合西医化疗治疗,除了可以提高患者对化疗的耐受性之外,还能明显提高患者的生存质量,当属一种值得临床推广及应用的治疗方法。
