放松利率管制、利润率均等化与实体企业“脱实向虚”

本文以我国贷款利率上下限放开为准自然实验,基于产权性质差异构造双重差分模型,实证考察放松利率管制如何影响实体企业金融化。研究发现:放松贷款利率下限管制能够显著抑制非国有企业金融化程度,而放松贷款利率上限管制则无显著作用,支持了“市场套利观”。机制检验发现贷款利率下限管制的放松显著抑制企业债务成本对企业利润的侵蚀作用;拓展性检验还发现对于盈利能力越强、规模越大以及市场竞争压力越小的公司,放松贷款利率下限管制对抑制非国有企业金融化的作用更显著。以上研究结论表明,实体经济与虚拟经济间的利润率差距是我国实体企业金融化的重要诱因,金融市场化改革有助于抑制实体企业金融化、改善“实体经济”与“虚拟经济”间的良性互动关系,从而助推实体经济的健康发展。     

互联网金融、存款竞争与银行风险承担

本文通过构建纳入互联网金融的银行环形城市模型,推演了“互联网金融→存款结构/付息成本→银行风险承担”的传导机制。在此基础上,以2003-2016年我国83家商业银行为样本,建立多重中介效应模型进行实证检验。研究结果表明:(1)互联网金融发展经由恶化存款结构和抬高付息成本两种渠道显著加重了银行风险承担水平,其中,恶化存款结构效应的相对贡献为50%左右,抬高付息成本效应的相对贡献为35%左右;(2)相较于互联网渠道构筑业态,互联网支付结算、互联网资源配置和互联网财富管理业态对银行存款结构和付息成本的不利影响更为强烈;(3)相对于国有、大规模、低流动性和低资本充足率商业银行,面对互联网金融的冲击,非国有、小规模、高流动性和高资本充足率商业银行的客户存款流失更快,平均付息成本上涨更多。     

Money: A Market Microstructure Approach

The new monetary economics predicts that deregulation and financial innovation will lead to a moneyless world. This paper uses a market microstructure approach to show that a common medium of exchange that serves as unit of account will remain a necessary instrument to reduce transaction costs. This finding is supported by empirical evidence from foreign exchange markets.     

Deregulation and oligopolistic rivalry in bank deposit markets

This paper provides a partial equilibrium analysis of a deregulated market for bank deposits in which banks behave oligopolistically but entry and exit are freely permitted. It is demonstrated that the effects of variations in market interest rates, reserve requirements, and bank cost and demand conditions upon the market quantity of bank deposit money are fundamentally altered if the degree of bank rivalry adjusts endogenously. Hence, banking deregulation may produce significant changes in the relationships between these variables and the stock of deposit money.     

Consumer deposit demand,interest rate differentials,and public welfare

Empirical estimates of the bank certificate of deposit demand schedule obtained in this study provide the basis for evaluating interest rate deregulation. A Box-Jenkins transfer function estimates bank deposit responses to intraindustry pricing changes and a sensitivity analysis shows microeconomic effects of interest rate differentials. The study concludes that 1) the public substantially subsidizes banks but banks achieve suboptimum deposit levels under thrift differential regulation, 2) removal of deposit rate regulation causes bank deposit demand schedules to shift slowly, not immediately, up with respect to interest rates, and 3) the consumer deposit demand curve is clearly interest elastic.     

Interest rate deregulation: Monetary policy efficacy and rate rigidity

This paper examines the effects of interest rate regulation, and subsequent deregulation, on the efficacy of monetary policy and rigidity of retail bank deposit rates in Hong Kong. Using an error-correction model, we find that interest rate deregulation increases the efficacy of monetary policy by improving the correlation between retail bank deposit rates and market interest rates and increasing the degree of long-term pass-through for retail bank deposit rates. Our study also shows that the adjustments in retail bank deposit rates are asymmetric and rigid upwards during the regulated period, but tend to be rigid downwards during the deregulated period. The spreads between retail bank deposit rates and market rates have also tightened sharply after the removal of interest rate controls.     

银行价格竞争、融资约束与企业研发投资——基于“中介效应”模型的实证研究

近年来我国利率市场化改革积极推进,实体经济发展积极向创新驱动转型,一个亟须研究厘清的关键问题是,银行业竞争如何驱动企业创新活动？本文关注银行价格竞争对企业创新的影响,以2013—2018年沪深两市的上市企业为样本,采用“中介效应”因果分析模型,实证检验了银行价格竞争对企业研发投资的影响,并识别出以融资约束为中介渠道的作用机制。研究发现,银行价格竞争不仅会提高银行的风险容忍度,直接增加R&D投资的信贷供给意愿,而且还会通过降低贷款价格和增加贷款可得性来缓解企业整体的融资约束,间接促进企业创新活动。这一机制在解除贷款利率管制之后以及在民营企业层面体现得更加明显。本文的研究结果对于深化金融市场化改革、改善金融服务实体经济效果以及实施经济创新驱动发展战略,具有明确的政策启示。     

An analysis of bank risk and deposit rate ceilings: Evidence from the capital markets

The effect of deposit rate regulation on bank solvency is an important and unresolved issue that has received only limited attention. In this paper, capital market data is used to assess changes in both systematic and non-systematic risk of a portfolio of bank stocks at the time of deposit rate deregulation. The evidence indicates that neither measure of capital market risk is significantly affected, leading to the conclusion that bank solvency risk will not be increased by the deregulation of interest rates on deposits.     

An Investigation of the Impact of Interest Rates and Interest Rate Volatility on Australian Financial Sector Stock Return Distributions

Abstract:   This paper extends the existing literature by analysing the dual impact of changes in the interest rate and interest rate volatility on the distribution of Australian financial sector stock returns. In addition, a multivariate GARCH‐M model is used to analyse the impact of deregulation on the financial institutions sector. It was found that there is a consistent inter‐temporal trade off between risk and return over the different regulatory periods. Moreover, finance corporations were found to be highly sensitive to new shocks across the financial sector and deregulation increased the risk faced by finance corporations and small banks – effectively increasing the required rate of return and explaining the continued rationalisation of these sectors. Furthermore, deregulation has changed the fundamental relationship between interest rates and large bank stock excess returns from positive in the pre‐deregulation period to negative in the post‐deregulation period. This reflects the changing institutional environment from one of controlled credit rationing to a more competitive environment.     

Deposit interest rates, asset risk and bank failure in Croatia

Financial deregulation, while beneficial in the long-term, seems to be linked to instability. Intense competition for deposits appears to be an ingredient in instability. We examine the aftermath of deregulation in Croatia, which included rapid growth of both deposits and deposit interest rates, followed by numerous bank failures.

Using panel regression techniques, we find evidence of “market-stealing” via high deposit interest rates. We connect high deposit interest rates to bank failure using logit models. High deposit interest rates were a reliable signal of risk-taking. When supervisory capabilities and powers are weak, deposit interest rate regulation may be worth considering.     

Adverse selection,search costs and sticky credit card rates

Several scholars of financial economics observed that during the 1980s, market interest rates declined continuously with little or no impact on credit card rates. Recently, Meyercord (1994), Sinkey and Nash (1993), and Sullivan and Worden (1995) recorded significant changes in the credit card market indicating an increased level competition. This study represents an attempt to determine the sensitivity of credit card rates to the costs of funds in the U.S. economy. The evidence from the Johansen Cointegration test confirms that credit card rates and cost of funds posses a long-run equilibrium relationship with one another. Furthermore, the results of the error correction models are indicative of a sluggish rate at which credit card interest rates adjust to the costs of funds. Between 1982 and 1994, credit card rates adjust to changes in the cost of funds at about 15 percent per quarter. These results represent anecdotal evidence for the validity of adverse selection, search and switch costs explanation that have been discussed in the financial contracting literature.     

The pricing of deposit insurance considering bankruptcy costs and closure policies

The paper aims to study the pricing issue of deposit insurance with explicit consideration of bankruptcy costs and closure policies. Full coverage from deposit insurance is imposed by many regulators to stabilize the banking system in the current financial crisis, despite of the potential moral hazard problems. We argue that bankruptcy cost is an important factor in pricing deposit insurance, especially when the insured institution is insolvent. Applying the isomorphic relationship between deposit insurance and put option, we first derive a closed-form solution for the pricing model with bankruptcy costs and closure policies. Then, we modify the barrier option approach to price the deposit insurance in which the bankruptcy cost is set as a function of asset return volatility and more realistic closure policies considering possible forbearance can be accounted for. The properties of the models are supported by numerical simulations and are consistent with the risk-based pricing scheme.     

Correspondent services and cost economies in commercial banking

Prior bank cost function studies have ignored the fact that some banks obtain a substantial amount of services from their correspondents. If these services are paid for with compensating deposit balances, their cost to the purchasing bank is not reflected in standard expense reports. This paper investigates whether explicit consideration of theese correspondent costs materially affects estimated bank returns to scale. The results indicate that the level of banksoperating costs is underreported by as much as 15%. While scale economy estimates for unit banks are not significantly affected by the addition of correspondent service costs, prior studies have overestimated branch bank scale economies by a small but statistically significant amount.     

Optimal Futures Positions for Large Banking Firms

In this paper, we extend earlier work on hedging models so that uncertainty about both deposit supply and loan demand is incorporated as well as random rates of return on loans and CD's. Our model suggests that the optimal forward position is the sum of three ratios that should be estimated simultaneously. Using bank-specific data, the optimal hedge ratios are estimated in both the pre-deregulation and deregulation subperiods. Our results show that previous studies of bank hedging with interest rate futures have greatly overstated (a) the volume of short futures positions that banks should take and (b) the degree of homogeneity of optimal hedge ratios across the banking system. Similarly, deregulation has not uniformly affected the interest rate risk borne by different institutions.     

The Financial Sector and Deregulation in Australia: Drivers of Reform or Reluctant Followers?

This paper argues that contrary to capture theory, a key feature of financial deregulation in Australia was the lack of support from financial sector interest groups. An examination of the Campbell Inquiry (1979-1981) reveals that deregulation was not initiated by either the regulated banks or unregulated non-bank financial institutions (NBFIs). In fact, both groups were resistant to change prior to the establishment of the Inquiry. During the Inquiry, neither group advocated wide-ranging deregulation, preferring the retention of many financial regulations.     

Entrepreneurial finance,credit cards,and race

This paper examines the impact of financial deregulation on entrepreneurship. We assess the impact of credit card deregulation on transitions into self-employment using state-level removal of credit card interest rate ceilings following the US Supreme Court's 1978 Marquette decision as a quasi-natural experiment. We find that credit card deregulation increases the probability of entrepreneurial entry, with a particularly strong effect for black entrepreneurs. We demonstrate that these effects are magnified in states with a history of racial discrimination and link the results to discrimination-based barriers to entry.

Variable-rate deposit insurance: A re-examination

This paper investigates the impact of variable-rate deposit insurance on the financial and real sectors of the economy and its role as an absorber of bankruptcy risk within these sectors. A variable-rate system raises the cost of funds to the real sector and increases probability of bankruptcy of the borrowing firms. When such bankruptcies occur, society experiences a dead weight loss. We argue that appropriate deposit insurance pricing must weigh the social costs connected with both financial firm failure and real-sector bankruptcy.     

Properties of time-series estimates of degree of leverage measures

Empirical studies suggest that time-series regression estimates of the degrees of operating and financial leverage have a tendency to produce measures less than one. According to ex ante theory, these measures should be greater than one for firms operating above the breakeven point. There have also been suggestions that the biases in these estimates may be attributable to an underlying increase in unit sales. This work presents evidence that these counter-intuitive measures are produced by changes in the firm's operating parameters (unit price, variable cost, fixed cost and interest payments). It further suggests that attempts to control for the underlying change in unit sales substantially increase the volatility of predicted estimates.
