房地产市场中存在大量的投资者,其市场行为会使房价出现大幅的波动,从而引起市场不稳定。文章在引入投资者异质性预期假设的基础上,构建了包含房地产消费者、投资者、供给者在内的房地产市场均衡模型,分析了房地产市场中基本面型投资者和趋势型投资者的异质性行为对房价变动的影响,并利用上海和广州两个一线城市的实际数据进行了对比分析。研究结果表明:在房地产市场中,两类投资者对于未来房价不同的预期以及投资行为会引起房价的变动;上海投资者的行为整体上会使上海的房价始终处于不断上涨的趋势中,而广州投资者的行为会随着投资策略的转变而使静态下的“整体上推动房价趋势型变化”转变为“整体上将房价‘拉回’基本面价格”;房地产市场中的投资者占比会显著影响房价的变动趋势,当基本面型投资者占比上升时,房价偏离度和房价变动率降低,而当这类投资者占比达到峰值时,房价会出现拐点;投资者之间的策略转换速度也会通过引起基本面型投资者占比的变化,引起房价的频繁波动,而且策略转换速度越快,房价波动越频繁。 相似文献

Research summary: The study explores renewal in a novel but understudied context—an era of ferment with competing technological options. It focuses on IBM's transition from market leadership in a failed path (plasma) to leadership in the emerging dominant technology (LCD) in the 1980s. Interviews and internal documents offer two primary factors explaining renewal at IBM. First, IBM Research had a hybrid structure that captured the benefits of both centralized and decentralized R&D. Second, middle managers shaped senior management cognitive frames to focus on business‐related issues instead of specific technical issues, thus bypassing biases often resulting from failure. The study offers an integrated framework on what facilitates flexibility at the technology, organization, and decision‐making levels. This flexibility helps firms survive a turbulent era of ferment. Managerial summary: Firms facing technological uncertainty may need to recover from unlucky bets. But responding to failure is politically and organizationally difficult. This study explores how IBM recovered from its failed bet on plasma displays to lead the LCD display market. This study identifies six key factors, highlighting two. First, IBM's researchers received centralized funding, but could also receive funding directly from division managers. This structure helped preserve options and variety. Second, internal LCD champions focused on the business case for displays and not technology. This fostered technology agnosticism and helped avoid managerial biases from failure. For managers looking to use real options to maintain flexibility in an uncertain environment, this study offers clear suggestions related to design and decision making that can foster flexibility.

This article empirically examines the importance of the credit channel of monetary policy in Mexico for the period 2004–2013. We estimate a vector autoregressive (VAR) model to analyse the effects of a monetary policy shock on real output, and we also use a threshold VAR model to investigate asymmetric effects of contractionary and expansionary policies. The empirical results suggest that a contractionary monetary policy results in a fall in the supply of loans together with an increase in the spread between the lending and deposit rate. To the extent that some borrowers are dependent on bank loans for credit, the reduced supply of loans amplifies the effects of monetary policy on output associated with the traditional interest rate channel. Our results also suggest that the importance of the credit channel is larger for contractionary shocks than for expansionary shocks. 相似文献

We suggest a Monte Carlo simulation-based unit root test of the purchasing power parity theory for Latin American countries. Under the null hypothesis, we use a Markov regime-switching (MS) model with unit root in the conditional location and MS volatility dynamics. Under the alternative hypothesis, the proposed test incorporates Markov regime-switching autoregressive moving average (MS-ARMA) plus MS volatility dynamics. Under both the null and alternative hypotheses, one of the volatility models estimated is Beta-t-EGARCH, which is a recent dynamic conditional score volatility model. We use data on real effective exchange rate time series for 14 Latin American countries. For each country, we estimate by Monte Carlo simulation the critical values of the unit root test. We provide an economic discussion of the unit root test results and also study the robustness of MS-ARMA plus MS volatility with respect to smooth transition autoregressive models with Fourier function. 相似文献

The purchasing power parity (PPP) is the hypothesis that the real exchange rate series are stationary. This study briefly reviews and applies six competing unit root test procedures to test PPP. Reflecting the existing literature, the results are mixed. The Kiliç test is the most favourable while the Kapetanios, Shin, and Snell (KSS) test is the least favourable to PPP and the standard ADF test lies in between. The same conclusion applies to the Fourier extensions of those three tests. The results support a recently suggested F-test for the significance of Fourier terms in unit root test equations. 相似文献

Household time preference for US households, as measured by the planning horizon, was fairly stable for many years, but sharply changed with the onset of the Great Recession. Based on an analysis of a combination of the 1992–2013 Survey of Consumer Finances (SCF) datasets, time preference increased in 2010 and remained high in 2013, indicating households were less patient after the onset of the recession. This pattern held up even after controlling for household characteristics. 相似文献

This article investigates the positive feedback trading strategies in the real estate markets of USA, Belgium/Luxembourg (Be/Lux) and Switzerland, linking these strategies with long-term volatility. The results are in favour of a positive feedback trading strategy which negatively influences investors' risk-return position on real estate markets. 相似文献

通过对房地产市场的实证研究,证实了资产市场资产价格的变化会影响到人们对未来经济形势的判断,进而影响到公众对未来消费品市场价格的判断,根据“预期自我实现”的原理,会对实际的通货膨胀或者通货紧缩产生影响。研究表明,房地产市场价格走势对通货膨胀预期的影响,要大于房地产市场资金变化对通胀预期的影响,所以监管层要管理好通货膨胀和通货膨胀预期,就要加强对资产市场尤其是房地产市场的监控,防止房价的大起大落。 相似文献
