We advance the idea that the predator-prey dynamics that take place among key market agents play an important role in explaining financial crises. As such, we posit that financial markets evolve through fault lines involving toxic behaviors (such as deceit), toxic products (such as predatory mortgages) and inefficient regulations. We provide data to show that the puzzle of the lack of congruence between the market behaviors and what some economic models predict at times of financial crises may be the result of predator-prey interplays, and of so-called “predatory cells”, which are under the influence of financial accelerators.  相似文献

Abstract

This study investigates the enhancement of human capital with social capital in a start-up accelerator and how this integration affects the entrepreneurial learning experience. In particular, it examines the relative importance of the three components ‘know-what’, ‘know-how’ and ‘know-who’. The study involved thematic analysis of semi-structured interviews with participants in an Australian start-up accelerator that is delivered using ideas such as Design Thinking, the Business Model Canvas and Lean Start-up methodology. We find that although the programme emphasised ‘know-what’ and ‘know-how’, ‘know-who’ was most significant for participant learning. The results indicate that mentors and experts were especially helpful in shaping learning and in developing entrepreneurial networks. Moreover, our results show that the processes of ‘know-what’, ‘know-how’ and ‘know-who’ are interrelated – by knowing ‘who’, participants learnt ‘what’ and ‘how to’ through social learning. The research contributes to entrepreneurial learning theory and application particularly in the Asia Pacific context, by providing evidence that ‘know-who’ closes the learning loop for ‘know-what’ and ‘know-how’ as ‘know-who’ can actually provide entrepreneurs with the means to enhance their entrepreneurial self-efficacy.  相似文献

Despite the widespread belief that technology shocks are the main source of business fluctuations, recent empirical studies indicate that in the absence of financial frictions, a shock to the marginal efficiency of investment is the main source and is closely related to financial conditions for investment. We incorporate a financial accelerator mechanism and two types of financial shocks to the external finance premium and net worth in a dynamic stochastic general equilibrium model with shocks to the marginal efficiency of investment, the investment-good price markup, and the rates of neutral and investment-specific technological changes. This model is estimated using eleven US time series that include data on loan, net worth, the loan rate, and the relative price of investment. Our estimation results show that the (non-stationary) neutral and investment-specific technology shocks primarily drive output and investment fluctuations, while the external finance premium shock plays an important role for investment fluctuations. This financial shock induced substantial falls and subsequent sharp hikes in the external finance premium and caused boom–bust cycles over the past two decades.  相似文献

This paper addresses the positive implications of indexing risky debt to observable aggregate conditions. These issues are pursued within the context of the celebrated financial accelerator model of Bernanke et al. (1999). The principal conclusions include: (1) the estimated level of indexation is significant, (2) the business cycle properties of the model are significantly affected by this degree of indexation, (3) the importance of investment shocks in the business cycle depends upon the estimated level of indexation, and (4) although the data prefers the financial model with indexation over the frictionless model, they have remarkably similar business cycle properties for non-financial exogenous shocks.  相似文献

融资融券设计初衷是通过融资加强市场流动性和通过融券提供投资者规避价格下跌风险的金融工具,改善由供求关系严重失衡导致市场巨幅震荡的局面,实现资本市场长期稳定的目标。实际操作中,融资融券疏通货币市场和资本市场间的资金流动,撬动巨额资金涌入股市;融资规模扩张过快而融券做空力量薄弱,业务结构发展严重失衡,导致两融业务具有“小冲击、大波动”的金融加速效应,放大了外部冲击引起股价上涨和下跌的幅度。协整回归分析表明,两融业务规模的扩张和收缩对上证指数涨跌具有显著的同向影响。TGARCH事件模型结果进一步证实融资融券从稳定股价到加剧波动的功能变化。随着标的股票扩容和业务常规化,两融业务导致股市投机过度,加剧了沪深两市的资产价格异动,没有达到平抑波动的设计预期。  相似文献

运用双向固定效应模型,实证分析了中部地区地方政府对金融发展的干预对金融加速经济发展的效应的影响。研究表明,在经济转型期,中部地区金融业的低水平稳态发展成为阻碍地区经济增长的不利因素。而地方政府因发展经济的强烈动机,适当干预金融发展能弥补地方金融自身发展的不足,促进金融发展推动地区的经济增长。  相似文献

本文在BGG模型基础上,建立了包含企业、金融中介、投资者的双重委托一代理模型,将金融中介纳入信贷市场摩擦的分析框架内。分析了金融中介自身受信贷约束时,其资产净值变化对经济产生的金融加速器效应。得出在双重委托代理的信用契约下,企业外部融资溢价不但受自身资产净值的影响,还受金融中介资产净值的影响。各种外部冲击通过信贷市场中金融中介的传导对经济波动造成进一步放大的效应,经济波动的金融加速器效应在考虑金融中介资产净值的影响后得到了增强。  相似文献

The financial crisis has brought the interaction between housing prices and household borrowing into the limelight of the economic policy debate. This paper examines the nexus of housing prices and credit in Norway within a structural vector equilibrium correction model (SVECM) over the period 1986q2–2008q4. The results establish a two way interaction in the long-run, so that higher housing prices lead to a credit expansion, which in turn puts an upward pressure on prices. Interest rates influence housing prices indirectly through the credit channel. Furthermore, households’ expectations about the future development of their own income as well as in the Norwegian economy have a significant impact on housing price growth. Dynamic simulations show how shocks are propagated and amplified. When we augment the model to include the supply side of the housing market, these effects are dampened.  相似文献

We analyze the determinants of corporate interest rates and the financial accelerator in the Czech Republic. Using a unique panel of 448 Czech firms from 1996 to 2002, we find that selected balance sheet indicators significantly influence the firmspecific interest rates. Debt structure and cash flow have significant effects on interest rates, whereas indicators on collateral play no significant role. Monetary policy has stronger effects on smaller firms than on medium-size and larger firms. Finally, we find no asymmetric effects in the monetary policy over the business cycle.  相似文献

在金融加速器理论中,货币政策会对实体经济产生过度冲击,甚至会造成经济的非平衡发展,主要表现在紧缩性货币政策会对小企业造成比较大的影响,引发小企业的融资难问题。从金融加速器作用机理的角度探讨当前中国小企业融资难问题,可提出相应的政策建议,使之符合中国经济的现实状况。  相似文献
