After-market liquidity and IPOs underpricing： Evidence from Shari＇ah and non Shari＇ah-based firms

The underpricing of initial public offerings （IPOs） is generally explained with asymmetric information and risk. We complement these traditional explanations with a new theory proposed by Ellul and Pagano （2006） where investors worry also about the after-market illiquidity that may result from asymmetric information after the IPO. The less liquid the after-market is expected to be, the larger will be the IPO underpricing. The samples are the 41 IPOs carried out between 2001-2005. The samples are 7 Shari＇ah-based firms and 34 non Shariah-based firms. Shariah-based firms are those included in Jakarta Islamic Index （JII）, at least one period （one semester）. Regression results show that the relationship between after-market liquidity and underpricing is insignificant unless we use trading frequency as proxy for liquidity for non Shariah-based firms.     

商业银行流动性过剩问题的再认识

最近,学术界对商业银行流动性问题议论颇多,议论的焦点是银行的流动性过剩及由此引发的种种后果.本文基于既往研究中值得深思的四个问题,从商业银行超额储备构成出发对流动性过剩的内涵、判断标准及影响因素进行界定,以商业银行保持流动性成因的微观视角管窥我国商业银行流动性过剩问题.在此基础上,本文认为商业银行流动性过剩问题的解决与资本市场的发展并无必然的直接联系,并针对流动性过剩问题的不同形成原因提出了相应的几点看法.

Fiscal Policy in a Currency Union at the Zero Lower Bound

This paper constructs a two‐country core–periphery New Keynesian model of a currency union to address the interaction between the objectives of regionally directed fiscal policy constrained by a single currency and the aggregate use of fiscal policy in face of the zero lower bound (ZLB) on policy interest rates. We identify an optimal path of aggregate and relative fiscal policy responses to a negative region‐specific demand shock. Our results show that (i) in a monetary union, the optimal policy response to an asymmetric reduction in demand concentrated in the periphery always entails a relative shift of fiscal expenditure toward the worse‐affected regions, (ii) though no aggregate fiscal response is required outside the ZLB, and (iii) optimal union‐wide fiscal policy is expansionary at the ZLB. Therefore, optimal policy always entails an expansion in the periphery at the ZLB, but the optimal fiscal response in the core regions can be either expansionary or contractionary depending on the parameters of the model. However, (iv) fiscal expansion in the core is warranted if the periphery cannot implement an expansion due to constraints on public spending.     

金融周期波动下银行流动性缓冲调整行为研究——来自美国银行业的经验证据

本文研究金融周期波动下银行流动性缓冲的调整行为,并采用1999-2018年美国4 719家银行的季度面板数据进行实证检验.研究结果表明:第一,银行持有流动性缓冲具有明显的顺周期效应;第二,银行业务特征会影响流动性缓冲的周期性调整:核心存款占比越高、贷款承诺越多的银行波动幅度越大;而批发融资占比越高、对证券化依赖程度越深...

流动性过剩与股票价格重估

在固定汇率与资本管制框架下,剩余储蓄的持续增加必然导致流动性过剩,对股票市场而言,只有当实体经济持续的剩余储蓄增加引起流动性过剩时,才会推动股票市场估值中枢的剧烈抬升.对近期经济指标的分析表明,股票市场重估将会持续下去,而货币政策紧缩引起的投资下降会进一步扩大剩余储蓄,加快重估的进程.
