美国银行关联交易监管演变考及借鉴

美国对银行业对外关联关系监管经历从“状态限制”到“行为限制”的发展过程,其理论基础是基于对银行独立市场判断能力的维护。我国应借鉴美国经验,加强对银行业关联交易的立法和外部监管,强化商业银行的内部控制;在监管中要兼顾效率和公平,加大对非公允关联交易的处罚力度,并赋予监管者一定的自由裁量权;不断修改、完善监管制度。

A counter-example to an option pricing formula under transaction costs

In the paper by Melnikov and Petrachenko (Finance Stoch. 9: 141–149, 2005), a procedure is put forward for pricing and replicating an arbitrary European contingent claim in the binomial model with bid-ask spreads. We present a counter-example to show that the option pricing formula stated in that paper can in fact lead to arbitrage. This is related to the fact that under transaction costs a superreplicating strategy may be less expensive to set up than a strictly replicating one.     

Bargaining Strength and Property Class in Office Markets

This paper examines the influence of bargaining power and property class on the prices of heterogeneous goods. Specifically, it explores the impact of buyer and seller characteristics on the transaction prices of office properties. The empirical model is based on the work of Harding, Rosenthal, and Sirmans (2003), which developed a method to distinguish between the impact of buyer and seller attributes on bargaining power and the choice of otherwise unidentified price effects (i.e., property class) in the context of hedonic price models. The data set contains information on transaction prices of office properties in Cook, DuPage, and Lake Counties, Illinois from 1995 to 1997. The results reveal systematic differences in bargaining power and property class for certain groups of buyers and sellers contained within the sample.     

The impact of the French Tobin tax

We analyze the impact of the introduction of the French Tobin tax on the turnover and measures of the liquidity and volatility of the affected stocks with nonparametric tests on individual stocks, difference-in-difference tests and other robustness checks controlling for simultaneous month-of-the-year and size effects. Our findings indicate that the tax produces a significant reduction in turnover and volatility (measured in terms of stock price volatility and the high–low price range) and inconclusive effects on liquidity when the latter is evaluated under the two dimensions of the estimated bid–ask spread and the Amihud (2002) price impact ratio.     

Market maker competition and price efficiency: Evidence from China

We test the relationship between market maker competition and stock price efficiency. Using the number of market makers as a proxy for competition, the results show a strong positive correlation between competition and stock price efficiency. Moreover, price efficiency is higher when competing market makers have higher research ability. We suggest that market maker competition increases price efficiency through two channels: 1) Competition decreases transaction costs, and 2) Uninformed market makers learn from orders submitted by informed market makers through competition. The latter happens only in the group of market makers with higher experiences. The results imply that the price efficiency can be improved by enhancing the competition of market makers with high research ability and experiences.     

The role of family management and ownership on semi-globalization pattern of globalization: The case of family business groups

Employing a multi-level with longitudinal concern data analysis this research examines the impact from family management and ownership on semi-globalization pattern of globalization in family business groups from an integrated framework. The results reveal that the more likelihood that the controlling family utilize family management in the subsidiary, and the higher degree of pyramidal ownership in the subsidiary, the more likelihood that the family business group will choose to engage in the host regions. Additionally, family management and pyramidal ownership is positively related with the choice to engage in a higher difference region instead of a lower difference region in family business groups. The theoretical and future research implications of these findings for family enterprises and globalization research are discussed.     

Policy responses to an overheated housing market: Credit tightening versus transaction taxes

Among Asian economies, Hong Kong has experienced the highest real growth in house prices since the 2010s. Two macroprudential measures, namely credit tightening (loan-to-value ratio cap) and transaction taxes (stamp duty), were introduced to cool down the overheated housing market. This study examines and compares their effectiveness based on a set of constant-quality house price indices. Through an error correction model, we find that credit tightening was able to curb house price growth in the high-price segment, while transaction taxes could not. An explanation is that the exemptions from transaction taxes for those with genuine housing needs could be abused by other market participants. It is easier for buyers to exploit the exemptions to get around the stamp duty than to manipulate the property valuation for mortgage lending. The implication is that the effectiveness of macroprudential measures hinges on whether compliance or exemption can be easily monitored and enforced.     

Incomplete privatization of public rental housing in Hong Kong

The delineation of the land occupied by Public Rental Housing (PRH) is a contentious issue in worldwide debates over PRH privatization. Heated arguments hold that governments should retain the occupied land for mitigating inequalities that privatization might provoke. Dual-role policies arise concerning both efficiency and equality. This research seeks to decode actual consequences of such policies based on their implementation in Hong Kong, with a specific focus on the Tenants Purchase Scheme (TPS). Intended to enliven PRH within needy families, the TPS policy instead resulted in dormant resale of privatized PRH with adverse effects on target groups. Hypotheses on how the TPS policy has affected housing resale are developed based on property rights and searching theories and tested against empirical data. This research offers a theoretical basis for exploring solutions to the unanticipated aftermath of Hong Kong’s PRH privatization and provides information for other governments on implications of privatization strategies.
