Price clustering on the limit-order book: Evidence from the Stock Exchange of Hong Kong

We examine the clustering pattern in trade and quote prices on the electronic limit order book of the Stock Exchange of Hong Kong (SEHK). Earlier research into clustering focuses on transaction prices only. We study clustering on quote prices over a maximum of five queues on the limit order book. We observe an abnormally high frequency of even and integer prices in trade and quote prices for all tick size groups on the SEHK. The deeper quotes display stronger clustering than the best quotes, indicating that the farther away the quotes are from the best queue, the less information they carry. Our analysis further reveals that an extremely fine tick size itself works as a binding constraint to hinder the price resolution process. We also find that short sale prohibition imposed on the majority of stocks listed on the SEHK causes a significant bias in clustering towards the ask side of the limit order book. This implies that a short sale prohibition impairs efficient price discovery in the market.     

Consumption, Housing Rents and Housing Price: A Test Of A Real Estate Pricing Model Using Hong Kong Data

The present study investigates whether Hong Kong's volatile real estate market is consistent with a non–linear consumption–based–asset–pricing model. It finds that the asset–pricing model is not rejected for some types of properties. However, the differentials between the returns to residential properties and risk–free rate are too large to be explained by the model.     

Hong Kong Output Dynamics: An Empirical Analysis

Abstract. Advanced statistical techniques are used to analyze Hong Kong output dynamics. Hong Kong, Japan and the US are found to share some common long‐term and short‐term cyclical variations. While the Hong Kong economy is susceptible to external shocks and Granger‐caused by the other two economies, local factors account for a large proportion of output growth variability and uncertainty. On the transmission mechanism, the selected trade and financial variables have incremental explanatory power but do not lessen the ability of lagged output variables to explain Hong Kong growth dynamics. Interestingly, the US does not appear to exert undue influences on Hong Kong.     

Cross‐country Relative Price Volatility: Effects of Market Structure*

Using annual data on nine manufacturing sectors of 18 OECD countries, the article studies the implications of market structure for cross‐country relative price variability. It is found that, in accordance with predictions from a standard markup pricing model, reductions in market competition, along with increased nominal exchange rate volatility, are associated with greater variability of cross‐country relative prices. The market structure also has similar effects on components of cross‐country relative price variability. The empirical findings are robust to the inclusion of various control variables and alternative sample specifications.     

Tunneling,propping, and expropriation: evidence from connected party transactions in Hong Kong

We examine a sample of connected transactions between Hong Kong listed companies and their controlling shareholders. We address three questions: What types of connected transactions lead to expropriation of minority shareholders? Which firms are more likely to expropriate? Does the market anticipate the expropriation by firms? On average, firms announcing connected transactions earn significant negative excess returns, significantly lower than firms announcing similar arm's length transactions. We find limited evidence that firms undertaking connected transactions trade at discounted valuations prior to the expropriation, suggesting that investors cannot predict expropriation and revalue firms only when expropriation does occur.     

ECONOMIC INTERACTIONS: CHINA VIS-A-VIS HONG KONG

Hong Kong's role has been integral to China's unprecedented economic growth, but privatization ranks first in importance. Another key factor is Beijing's putting economic reform before political reform. Giving democracy to a society in chaos likely makes matters worse. Hong Kong and China both have profited from their partnership. As China has opened up to allow transformation into a market economy, Hong Kong has provided informational impetus for change, a capitalist model to copy, and middleman functions for China to participate in outside-world goods and financial markets. The collapse of Communism in China and elsewhere has increased the supply of cheap labour perhaps by 2 billion. Manufacturing countries with expensive labour and high cost welfare programmes—such as those in the United States, Canada, and Europe—will have difficulty. Capitalists in these countries will do well by investing abroad but not in their own countries. Though wrong in detail, the factor price equalization theorem—that international movement of goods and international movement of factors of production are equivalent—basically is correct. If China continues moving toward privatisation and joining the international community, it will become fiercely competitive, and prospects will be bright for both China and Hong Kong. However, China's recent drift from capitalism clouds those prospects. Fundamentally, three kinds of rights systems exist: (i) a capitalist system, with well defined private property rights, protected by law, where control of resources is based on ownership; (ii) a hierarchical system, such as Communism, where control of resources is based on one's rank in the hierarchy; (iii) a system of corruption, where control of resources is based on bribes and patronage. China rapidly had been making a transition from the second system to the first but recently seems to have derailed into the third. In any case, Communism's collapse is one of the great events in human history. The hero of that event is Deng Xiaoping—not Gorbachev, nor Thatcher, nor Reagan. Hong Kong, by contributing significantly to China's capitalist movement, has led the Communist world to change.     

Information disclosure quality: correlation versus precision

We investigate how a multidimensional disclosure quality (i.e., correlation and precision) determines an optimal information disclosure strategy. We find that, for an infinitely lived, unlevered firm with market perfection, a truth‐telling disclosure is optimal at increasing the expected firm value. However, for a finitely lived, levered firm in the presence of market imperfections (e.g., bankruptcy cost), the optimal disclosure quality depends negatively on the level of imperfections. Once we consider the agency problem, such dependence can become positive, thereby highlighting the importance of a proper managerial‐incentive scheme to align the information disclosure interests of managers and shareholders.     

Tail mutual exclusivity and Tail-VaR lower bounds

In this paper, we extend the concept of mutual exclusivity proposed by [Dhaene, J. & Denuit, M. (1999). The safest dependence structure among risks. Insurance: Mathematics and Economics 25, 11–21] to its tail counterpart and baptize this new dependency structure as tail mutual exclusivity. Probability levels are first specified for each component of the random vector. Under this dependency structure, at most one exceedance over the corresponding Value-at-Risks (VaRs) is possible, the other components being zero in such a case. No condition is imposed when all components stay below the VaRs. Several properties of this new negative dependence concept are derived. We show that this dependence structure gives rise to the smallest value of Tail-VaR (TVaR) of a sum of risks within a given Fréchet space, provided that the probability level of the TVaR is close enough to one.
