开放经济中的金融安全问题及其保障对策

在开放经济体系中，金融安全至关重要，它构成了产业安全的核心内容。一般认为，金融安全是指一国能够抵御内外冲击保持金融秩序和金融体系正常运行与发展的状态以反维持这种状态的能力和对这种状态与维持能力的信心与主观感觉，包括在这种状态和能力下所获得的政治、金融制度和体系的安全、金融财富的安全、金融机构的安全、金融发展的安全，对整体经济和政治安全起决定性作用的金融运行的安全等。发展中国家尤其应当重视金融安全问题，通过各种有效的措施积极防范和化解金融风险，保障金融安全。     

Equilibrium real interest rates and the financial cycle: Empirical evidence for Euro area member countries

We estimate the equilibrium real interest rate for nine Euro area member countries and the Euro area as a whole using quarterly data from 1995 to 2015. We expand the standard model of estimating real equilibrium interest rates to incorporate the financial cycle for the private sector. We show that adding the financial cycle indeed alters the equilibrium real interest rate estimates and, in line with previous studies, that there is a fall in the equilibrium real interest rate over time. Our results indicate that in most member countries the real rate is lower than its equilibrium level. Hence, they should not worry about secular stagnation now. This is because secular stagnation is likely to occur when real interest rates are higher than their equilibrium levels. This result can serve as a starting point for further research in this field, e.g. by adding public sector financial cycles or disentangling the roles of households, corporations and the government.     

Financial crises,exchange rate linkages and uncovered interest parity: Evidence from G7 markets

This paper examines the dynamic linkages among major exchange rates during the Global Financial Crisis and Eurozone Sovereign Debt Crisis. We extend the previous literature on volatility spillover linkages among the currencies by taking into account the uncovered interest-rate parity hypothesis for 2004–2015. The results indicate that the Canadian Dollar and Great British Pound were affected mainly by the US Dollar across the two crises due to strong financial and economic ties among the three economies, while the Japanese Yen shows evidence of a safe-haven currency. We also provide evidence of varying vulnerability of currencies to both crises, implying increased portfolio diversification benefits, since holding a portfolio with diverse currencies is less subject to systematic risk. These results show that the policy makers need to adopt a stricter form of monetary policy coordination among central banks, since the different vulnerability of currencies across turbulent periods reveals possible non-cooperative monetary policies.

Equilibrium interest rate and liquidity premium with transaction costs

Summary. In this article we study the effects of transaction costs on asset prices. We assume an overlapping generations economy with two riskless assets. The first asset is liquid while the second asset carries proportional transaction costs. We show that agents buy the liquid asset for short-term investment and the illiquid asset for long-term investment. When transaction costs increase, the price of the liquid asset increases. The price of the illiquid asset decreases if the asset is in small supply, but may increase if the supply is large. These results have implications for the effects of transaction taxes and commission deregulation. Received: December 5, 1997; revised version: March 19, 1998

Asymmetric information and survival in financial markets

Summary. In the evolutionary setting for a financial market developed by Blume and Easley (1992), we consider an infinitely repeated version of a model á la Grossman and Stiglitz (1980) with asymmetrically informed traders. Informed traders observe the realisation of a payoff relevant signal before making their portfolio decisions. Uninformed traders do not have direct access to this kind of information, but can partially infer it from market prices. As a counterpart for their privileged information, informed traders pay a per period cost. As a result, information acquisition triggers a trade-off in our setting. We prove that, so long as information is costly, uninformed traders survive.JEL Classification Numbers: D50, D82, G14.I am deeply indebted to Luca Anderlini for his helpful guidance. I also benefited from discussion with Larry Blume, David Easley, Jayasri Dutta, Thorsten Hens, Hamid Sabourian, Klaus Reiner Schenk-Hoppé and Hyun Song Shin.

Synchronisation and staggering of interest rate change by UK financial services firms

This study examines the frequency and form of deposit account interest rate change. Specifically the question of whether deposit interest rate change is synchronised with other banks or staggered at periodic intervals is addressed. Overall, evidence consistent with individual banks changing deposit interest rates in a staggered manner is recorded. Further larger banks are seen to change interest rates in a more synchronised manner than smaller banks. Lastly, when banks offer multiple deposit accounts, these products' interest rates are generally changed simultaneously by individual banks. These findings extend the current understanding of deposit interest rate change, and indicate that UK deposit interest rate setting is relatively rigid.     

The role of transaction costs and risk aversion when selecting between one and two regimes for portfolio models

Estimation of the inputs is the main problem when applying portfolio analysis, and Markov regime-switching models have been shown to improve these estimates. We investigate whether the use of two-regime models remains superior across a range of values of risk aversion and transaction costs, in the presence of skewness and kurtosis and no short sales. Our results for US data suggest that, due to differences in their risk preferences and transactions costs, most retail investors may prefer to use one-regime models, while investment banks may prefer to use two-regime models.     

金融发展中稳定与效率的"二难"选择

作为现代经济的核心，金融业的发展既离不开金融稳定，也离不开金融效率。金融发展应以金融稳定为基础，以提高金融效率为目标。然而，金融业发展的事实却表明，金融发展总是呈现在稳定与效率的博弈状态之中，很显然，这对实现经济发展以及保障金融体系的稳定是十分不利的。     

The role of the financial system in the growth–inflation link: the OECD experience

This paper jointly estimates the effects of financial development and inflation on growth using both cross-section and time-series dimensions of the data on inflation, growth, and some banking and stock market indicators over the period 1961–1993 for a sample of OECD countries. Overall, the results indicate, first, that the long-run costs of inflation are not explained by policies of financial repression and, second, that if inflation affects growth through its interaction with financial market conditions, this is not the only (nor the most important) channel.     

Income shifting, investment, and tax competition: theory and evidence from provincial taxation in Canada

We study corporate income taxation when firms operating in multiple jurisdictions can shift income using tax planning strategies. Because income of corporate groups is not consolidated for tax purposes in Canada, firms may use financial techniques, such as lending among affiliates, to reduce subnational corporate taxes. A simple theoretical model shows how income shifting affects real investment, government revenues, and tax base elasticities, depending on whether firms must allocate income to provinces or not. We then analyze data from administrative tax records to compare the behavior of corporate subsidiaries that may engage in income shifting to comparable firms that must use the statutory allocation formula to determine their taxable income in each province. The evidence suggests that income shifting has pronounced effects on provincial tax bases. According to our preferred estimate, the elasticity of taxable income with respect to tax rates for “income shifting” firms is 4.9, compared with 2.3 for other, comparable firms.     

The wealth effect and diamond risk structure of financial regulation

The objective of this article was to evaluate the effect of announcements of financial regulation on risk and return in the Vietnamese equity market. The techniques used for the purpose of analysing risk and return include event study and non-parametric tests, as well as asset pricing models supplemented with interaction variables and a variety of ARCH-like specifications such as GARCH, TARCH, EGARCH and PARCH. We find evidence for the wealth effect, the presence of delayed response and a risk shifting behaviour in the form of diamond risk structure. Our results show that abnormal returns are present around the announcements of operating rules and other stock market regulations. Abnormal returns can also be obtained after considering legal documents such as circulars and decisions.     

Economic development and financial depth in a model with costly financial intermediation

According to Gurley and Shaw, economic development typically is accompanied by a transition from self-financed to intermediated investment activity. In their account, economic growth stimulates financial market development, and financial market development is a strong contributing factor in enhancing real growth. We model the co-evolution of the real and financial sectors during the growth process. To do so, we embed a role for liquidity provision into a conventional neoclassical growth model. Following Baumol and Tobin, we also introduce a fixed cost associated with “trips to the bank”. We describe conditions under which the development of a financial system may or may not proceed smoothly. When it does not, development traps are observed. We also discuss policy interventions that may reduce the potential for development traps to arise.     

Optimism bias in financial analysts' earnings forecasts: Do commissions sharing agreements reduce conflicts of interest?

Implemented in May 2007, the French rules governing commission-sharing agreements (CSAs) consist of unbundling brokerage and investment research fees. The goal of this paper is to analyze the effect of these rules on analysts' forecasts. Based on a sample of one-year-ahead earnings per share forecasts for 58 French firms during the period from 1999 to 2011, we conduct panel data regressions. We show that the analysts' optimistic bias declined significantly after CSA rules, which suggests that these rules are effective at curbing the conflicts of interest between brokerage activities and financial research. Our results are robust to the impact of the Global Settlement and the Market Abuse Directive.

Reserve accumulation and financial crises: From individual protection to systemic risk

This paper provides a new perspective on the relationship between countries׳ international reserve holdings and financial crises: while the “local” view holds that reserves may prevent domestic crises, it overlooks that the accumulation of reserves relaxes the financing constraint of the reserve currency country and may cause a financial crisis in the centre, which is transmitted globally. According to this “global” view reserve accumulation might destabilize the international financial system. Since the crisis affects all countries alike, the accumulation of reserves imposes a negative externality on non-accumulating countries.We integrate this idea in a theoretical model of the optimal amount of reserves and illustrate the gap between local and global optimality: the consideration of systemic risk lowers the demand for reserves. Moreover, if a supranational authority determines the optimal level of reserves, it internalizes the negative externality and accumulates fewer reserves. A macroprudential tax on reserve hoardings might implement the socially optimal solution. Our calibration analysis shows that these considerations are economically significant: they lower the optimal amount of reserves in the benchmark case by 45%.     

EMS exchange rate expectations and time-varying risk premia

In this paper we examine exchange risk premia employing a survey dataset of EMS exchange rates. We are able to test a risk premium model directly, i.e. without having to rely on the rational expectations assumption. Our results indicate that time-varying risk premia are present in almost all cases and that a GARCH-in-mean specification for the premium is often appropriate.
