Residential Asking Rents and Time on the Market

Landlords offering a house in the rental market face a difficult strategic pricing decision. The revenue maximizing decision for the landlord involves a tradeoff between the rental rate and time on the market. Because the turnover of renters is higher than owners, and because the landlord must bear some carrying costs on a vacant house, pricing the rent too high may decrease revenue due to a higher vacancy period and pricing it too low may reduce the revenue when occupied. While there is substantial research on the relationship between listed prices and time on the market for freehold interests, this is the first study to provide empirical evidence on the relationship between asking rent, contract rent and time on the market for single family residential rental (leasehold) property interests. We present two models; a rental price model and a duration model for time-on-the market. Using data from the Dallas–Fort Worth area we find that landlords who set a lower asking rent relative to predicted rent can expect a shorter marketing period for their properties. The results also indicate that overpricing the asking rent and then lowering it at a later date leads to a longer marketing time (after the reset) and often a lower rent. These finding are reasonably robust for low-, mid-, and higher-valued rental properties.

Policy induced increases in private healthcare financing provide short-term relief of total healthcare expenditure growth: Evidence from OECD countries

Healthcare reforms have long been advocated as a cure to the increasing healthcare expenditures in advanced economies. Nevertheless, it has not been established whether a market solution via private financing, rather than public financing, curb aggregate healthcare expenditures. To our knowledge, this paper is the first that quantifies the impact of reforms that significantly increases (decreases) the private (public) share of healthcare financing on total healthcare expenditures relative to income in 20 OECD countries. Our reform measure is based on structural break testing of the private share of total expenditures, and verification using evidence of policy reforms. To quantify the effect of these reforms we apply Propensity Score Matching and Inverse Probability Weighted regression analysis. Over a 5-year evaluation period the reforms lead to an accumulated cost saving 0.45 percentage points of GDP. The yearly effects of the reforms are largest in the first years in the post-reform period and decreases in size as a function of time since the reform. Our findings suggest that the investigated healthcare reforms have a relatively short-lived effect on aggregate health spending relative to GDP. The findings are robust to various sensitivity tests.     

我国农村饮用水安全现状、问题及政府管制

农村饮用水安全是关系农村居民生活质量和生命安全的大问题。农村饮用水安全具有公共性,需要政府进行管理。我国农村饮用水安全问题主要体现在水质差、水量不足、取水不便、不能保证供给等方面。为此,需要政府投入和民间筹资多方支持,同时政府应加大宣传力度,加强农村配套设施建设,以消除农村饮用水存在的安全问题和隐患。     

Country Differences in Material Deprivation in Europe

This paper assesses to what extent differences in the characteristics of individuals (micro‐level perspective) and country‐specific factors (macro‐level perspective) can explain country differences with respect to material deprivation levels. Thus, our work aims to simultaneously consider the macro dimension and the predominantly individually‐oriented study field of material deprivation using multilevel techniques. We make use of the European Union Statistics on Income and Living Conditions. Our results show that country‐specific factors seem to be much more relevant than individual effects in explaining country differences in material deprivation. We estimate that the introduction of country‐specific factors reduces the proportion of total variance due to between‐country differences in deprivation by 72.7 percent, while individual‐level variables reduce this proportion by only 9.4 percent. We also show, through interaction variables, that the effect of sociodemographic characteristics can be shaped by institutional and structural factors, especially by the level of GDP.     

利率管制松绑、企业会计信息披露质量与融资约束

已有研究发现,以资本价格——利率为代表的要素市场改革会对企业行为产生重要影响,但这种影响的作用机理如何通过改变资本市场中的信息供求关系予以实现,亟待深入研究。为此,本文以我国2013年央行全面放开利率管制为背景,基于产权性质差异构建双重差分模型,检验利率管制松绑在企业层面的信息溢出效应。研究发现:央行全面放开利率管制不仅有助于促进企业披露高质量的会计信息,还能够缓解企业的融资约束,且企业信息披露质量的提升是导致利率管制松绑降低融资约束的重要渠道。进一步研究发现,对于市场化程度较低地区、R&D投入较高以及短期贷款占比较大的公司,上述信息溢出效应更加显著;另外,利率管制松绑后企业披露高质量的会计信息能够增进投资者的信任,提高信息披露的价值相关性。以上研究结论表明,为应对利率市场化改革带来的机遇与挑战,保障可持续发展,企业会选择主动优化信息环境,来消除信贷市场摩擦,解决"融资难"问题。     

基于时间序列的BP神经网络预测鄂尔多斯市的GDP

国内生产总值(GDP)是制定经济发展战略、规划、年度计划以及各种宏观经济政策的重要依据,研究GDP预测方法具有重要的现实意义。在对鄂尔多斯市GDP数据序列分析的基础上,考虑到BP神经网络可以通过简单非线性函数的复合能够实现对于复杂函数的映射,本文采用BP神经网络方法来预测鄂尔多斯市的GDP,取得了较好的预测效果。     

我国高校科研“投入产出最小化”现象成因与对策研究

高校虽是我国三大科研主体之一,但其科研活动却广受诟病。在已有研究的基础上,深入分析我国高校科技成果转化率较低的主客观原因,发现高校科研系统存在着“投入产出最大化”悖论。基于“外部性”与“零和博弈”等经典理论,提出了“投入产出最小化”概念。根据“投入产出最小化”现象的本质和成因,从强化激励、加强监管、改善环境3个方面提出了系统性对策与建议。“投入产出最小化”现象的提出,为分析当前高校科研活动绩效提供了新的研究视角,对相关问题的进一步探讨具有借鉴意义。     

战略联盟组织的稳定性、组织治理与信用约束机制

本文运用博弈论的分析框架分析了战略联盟组织不稳定性的原因在于战略联盟组织的中间组织性质所导致的战略联盟组织对机会主义行为约束的弱化,进而揭示了战略联盟组织稳定的关键在于组织内成员的博弈支付结构和博弈者对未来的预期。在此基础上,从组织治理结构的角度提出了稳定战略联盟组织应建立有效的信用约束机制的结论,阐述了这一机制的目标和内容,并针对我国战略联盟组织所面临的问题提出了相应的对策。
