随着房地产市场的繁荣发展,房地产交易主体之间的法律关系也日益复杂,《物权法》中规定了不动产登记制度不仅有利于保障公民的财产权,也有利于保障市场交易安全。文章针对《物权法》的相关规定,提出了我国房地产登记制度的必要性以及存在的问题和完善建议。     

An empirical test of the Balassa-Samuelson hypothesis: Evidence from eight middle-income countries in Africa

The paper tests the validity of the Balassa-Samuelson hypothesis (BSH) using the within-effects and the dynamic panel generalised methods of moment (GMM) techniques for a panel of eight middle-income African countries over the period 1960–2009. We selected these countries because they exhibited a mixture of relative productivity growth and real exchange rate misalignment that fits the characterization of the BSH well. The results strongly support the BSH for this group of countries. The results are valid even after we controlled for potentially omitted variables and endogeneity. The implication is that as these countries become more productive, their currencies appreciate in real terms.     

Hedge fund seeding via fees-for-seed swaps under idiosyncratic risk

We develop a dynamic valuation model of the hedge fund seeding business by solving the consumption and portfolio-choice problem for a risk-averse manager who launches a hedge fund through a seeding vehicle. This vehicle, i.e. fees-for-seed swap, specifies that a strategic partner (seeder) provides a critical amount of capital in exchange for participation in the funds revenue. Our results indicate that the new swap not only solves the serious problem of widespread financing constraints for new and early-stage funds (ESFs) managers, but can be highly beneficial to both the manager and the seeder if structured properly.     

Land prices and unemployment

We integrate the housing market and the labor market in a dynamic general equilibrium model with credit and search frictions. We argue that the labor channel, combined with the standard credit channel, provides a strong transmission mechanism that can deliver a potential solution to the Shimer (2005) puzzle. The model is confronted with U.S. macroeconomic time series. The estimation results account for two prominent facts observed in the data. First, land prices and unemployment move in opposite directions over the business cycle. Second, a shock that moves land prices also generates the observed large volatility of unemployment.     

金融发展、资产泡沫与实体经济: 一个文献综述

近年来的金融危机和不同国家的发展路径促使经济学家们反思资产泡沫与实体经济之间的关系。过去几年主流经济学中开始涌现出一些富有洞见的相关理论和实证文献。本文通过一条逻辑主线对基于这些文献的进展进行了系统评述。资产泡沫产生于金融市场的不完全性,它既影响实体经济的效率和增长,也影响实体经济的波动。其中,金融发展程度(金融市场的完全性)扮演了重要的角色。金融发展程度会影响到资产泡沫的产生;而资产泡沫既可以缓解经济中的扭曲,也可以加剧经济中的扭曲,使得经济增长偏离黄金律。制度质量则会强化金融发展程度的影响。金融发展程度与制度质量在开放经济的情况下,还会影响到资本在国际间的流向和结构,从而对实体经济的增长和波动产生更复杂的影响。本文中所综述的理论洞见对于中国这类金融市场欠发达、正面临金融自由化与结构转型的新兴市场经济体尤其具有重要的政策含义。本文最后讨论了中国金融改革和金融发展中需要注意的一些问题。     

房地产开发企业资金运行机理及风险控制研究

房地产开发企业作为市场主体,从事的是典型的资金密集型产业生产,因而存在具有高风险运行性质的企业资金链,同时作为典型项目型企业,通常还包括多条相对独立的项目资金链,是由相互作用来共同影响企业的运营和发展。本文对资金链的内在运行机理进行了剖析,对其运行风险及影响因素进行了分析并提出了相应的防控措施,以期为房地产企业资金链的安全和稳健运行提供参考。     

Risk, uncertainty, and option exercise

Many economic decisions can be described as an option exercise or optimal stopping problem under uncertainty. Motivated by experimental evidence such as the Ellsberg Paradox, we follow Knight (1921) and distinguish risk from uncertainty. To capture this distinction, we adopt the multiple-priors utility model. We show that the impact of ambiguity on the option exercise decision depends on the relative degrees of ambiguity about continuation payoffs and termination payoffs. Consequently, ambiguity may accelerate or delay option exercise. We apply our results to investment and exit problems, and show that the myopic NPV rule can be optimal for an agent having an extremely high degree of ambiguity aversion.     

EKC-type transitions and environmental policy under pollutant uncertainty and cost irreversibility

Previous studies have suggested that some pollutant levels first increases due to the economic growth and then start decreasing, the pattern being called the “environmental Kuznets curve” (EKC). We examine EKC-type transitions of pollutant levels not with respect to economic growth but more generally in time. Assuming that each policy maker optimally executes the two switching options of regulation and unregulation for pollution, the switching dynamics of environmental policy can be described by an alternating renewal process. It is shown that the double Laplace transform of transition density of a pollutant level can be obtained by a novel application of renewal theory. The expected level of overall pollutants is then calculated numerically and found to exhibit either a Λ‐shaped or an N-shaped pattern in time. Our results present a simple explanation for the EKC-type transitions of pollutant levels within a real options framework.     

基于DEA的绿色经济增长核算:以中国地区工业为例

本文构建基于DEA的绿色经济增长核算模型,将考虑非期望产出的劳动生产率变化分解为技术效率变化、技术进步和资本深化。中国地区工业的经验分析表明,与发展水平无关且省际差异大的技术无效率普遍存在;各省工业增长的首要源泉是资本深化,其次是技术进步主导的全要素生产率进步;各省工业劳动生产率增长差异主要源于资本深化差异,其次是技术效率变化差异主导的全要素生产率进步差异;如不考虑非期望产出,会低估资本深化对经济增长的贡献,高估技术进步的贡献,而技术效率变化的贡献可能被高估、低估或无影响。     

品牌战略：新房地产时代发展的必由之路

随着中国房地产市场由供不应求向供求平衡转变,房地产行业也将会不可避免地进入品牌时代,但目前中国房地产品牌创建还处在滞后的阶段,一些不利于地产品牌建设的认识还在大行其道,究竞该如何建设房地产品牌已经成为业界所面临的一个紧迫问题。因此,有必要对此作进一步的深入研究。
