黑龙江省对俄贸易发展存在的问题及对策研究

目前,黑龙江省在对俄贸易、投资、经济技术合作等方面取得巨大成绩的同时,还存在着一系列急需解决的问题：对俄贸易企业的整体实力不强;进出口商品结构单一;商品货物贸易层次较低;出口产品技术含量低;缺乏本省名牌产品;市场贸易秩序与服务贸易体系不健全等,影响和制约了对俄贸易的进一步发展。促进对俄贸易的发展,必须转变外贸形式,优化贸易产品结构,着力打造本土企业品牌,提高商品技术含量,拓展能源原材料投资合作领域。同时,坚持＂以俄为主、注重日韩、兼顾其他＂的原则,大力开拓国际市场,从而促进黑龙江省对外贸易快速发展。     

我国当前运动心理咨询中存在的问题探析

从上个世纪八十年代开始,我国开始关注运动员的心理状态,从1986年的我国第六届全运会第一次设立心理咨询机构,到2007年我国第一批运动心理咨询专家获得认证。我国运动心理咨询领域在这二十几年中得到了一定的发展。但是,相较于国外成熟完善的运动心理咨询体系,我国现有的运动心理咨询还存在一些不足。本文作者通过分析我国目前运动心理咨询中存在的问题,旨在促进我国运动心理咨询的发展,进而更好地提高我国运动员的心理素质,为运动员们在世界性范围内的体育比赛中取得优异成绩做好充足准备。

Health shocks and mortgage debt payoff among American homeowners over age 50: A survival analysis

Mortgage debt is financially burdensome for many older homeowners in the United States. As people age, declining health can bring about increased healthcare costs. Focusing on homeowners aged 50 and older in the U.S., we investigate two research questions: (1) To what extent does a heath shock affect the likelihood of paying off a mortgage voluntarily or involuntarily? and (2) how long does a health shock delay the time it takes to pay off a mortgage? We used eight biannual waves (2004–2018) of the Health and Retirement Study containing 11,772 borrowers to build survival regression models. Results showed that a health shock reduced the likelihood of voluntary payoff by 12%, while it increased the probability of involuntary payoff by 18%. A health shock delayed voluntary and involuntary payoffs for 30 and 21 months, respectively. We discuss tax deduction and HELOCs as strategies to reduce older homeowners' mortgage strain.     

The out-of-sample forecasting performance of nonlinear models of regional housing prices in the US

This article provides out-of-sample forecasts of linear and nonlinear models of US and four Census subregions’ housing prices. The forecasts include the traditional point forecasts, but also include interval and density forecasts, of the housing price distributions. The nonlinear smooth-transition autoregressive model outperforms the linear autoregressive model in point forecasts at longer horizons, but the linear autoregressive and nonlinear smooth-transition autoregressive models perform equally at short horizons. In addition, we generally do not find major differences in performance for the interval and density forecasts between the linear and nonlinear models. Finally, in a dynamic 25-step ex-ante and interval forecasting design, we, once again, do not find major differences between the linear and nonlinear models. In sum, we conclude that when forecasting regional housing prices in the United States, generally the additional costs associated with nonlinear forecasts outweigh the benefits for forecasts only a few months into the future.     

我国公民住房权保障的宪法学透视

住房权是指公民获得可负担得起的适宜于人类居住的,有良好的物质和基础设施服务设施的,具有安全、健康、尊严,并不受歧视的住房的权利。目前房价高企,保障性住房不足,非法驱逐现象普遍,公民的住房权没有得到充分保障。从宪法的角度而言,我国现行房地产制度违背了法律保留原则、制度性保障原则、平等保护原则、正当程序原则等诸多宪法原则,亟待完善。为了保障公民的住房权,我国应及时出台保障公民住房权的基本法律,重构土地交易制度、公积金制度,恢复单位集资建房、支持公民合作建房,建立非法建筑的权益保障制度,完善住房保障体系。

制度缺失与中国经济体制改革面临的三大问题

经济体制改革以来,由于制度缺失的存在,致使经济体制改革在取得辉煌成就的同时,也面临着市场化改革所带来的严峻经济问题,这些问题突出地表现在以下三个方面:一是日益凸现的失业问题;二是财富分配不公问题;三是国有资产流失问题。制度缺失导致的这三个问题,加重了改革的社会成本,危害了社会公平,破坏了经济效率,因此必须采取相应的治理措施。     

What Drives the Property Price-Trading Volume Correlation? Evidence from a Commercial Real Estate Market

The significant price-trading volume correlation found in the residential property market presents a challenge to the rational expectation hypothesis. Existing theories account for this fact with either capital market imperfection (down-payment effect or loss-aversion consideration) or imperfect information (search theoretic models). This paper employs data from a commercial real estate market, which face a different degree of severity of capital market constraint than the residential market, and thus provide an indirect but effective test for alternative theories. Policy implications are also discussed.
