Free Float And Market Liquidity: A Study Of Hong Kong Government Intervention

The August 1998 Hong Kong government intervention in the stock market offers a natural experiment for studying the relation between a free float and market liquidity, where a free float is the portion of listed share capital that is freely traded on the market. Our findings show that, relative to a group of control stocks, there was an increase in the price effects of trades for the 33 Hang Seng Index component stocks that were bought by the government. On the other hand, there was no clear cross‐sectional relation between the change in the price effect and the magnitude of government holdings or the decrease in the free float.     

The interaction of the financing and investment decisions: Preliminary results in the Australian context

This paper investigates the presence of the interaction of investment and financing decisions in Australian firms. Using simultaneous equations incorporating the variables of investment, dividend, and new debt issue, interactive effects are found for two sub-periods.     

SYSTEMATIC RISK IN A PURELY RANDOM MARKET MODEL: SOME EMPIRICAL EVIDENCE FOR INDIVIDUAL PUBLIC UTILITIES

A minimum norm quadratic (MINQU-) type of OLS estimator is derived. The estimator is used to test if the betas of the single factor market (SFM) model are random for a sample of utilities for two contiguous periods. The estimated betas for individual utilities vary considerably over time. The statistical significance of such nonstationarity depends on both the utilities and period studied. The relative reduction in the mean square error (MSE) from using a GLS (and not OLS) estimator of beta, when beta is purely random, can be substantial for some utilities but is modest on average.     

HRM systems and firm performance: The mediation role of strategic orientation

Prior research evidence of a set of internal fit human resource practices supports a positive human resource management (HRM)–performance relationship. Yet we know very little about exactly what drives the HRM–performance (also known as strategic HRM) relationship. In response to the call for suitable theories to explore the “black box” between HRM and firm performance, this study is designed to extend previous work by examining how the relationship between HRM and strategic orientation influences firm performance. Specifically, it examines the relationship between HRM systems, strategic orientation, and performance in a cross-section of 190 firms in Singapore. The research hypotheses were tested using multiple regression and LISREL. As predicted, there was an indirect effect between Inducement and Investment HRM systems and firm performance, such that the relationship was mediated by strategic orientation. In particular, Singaporean firms which implemented product and market differentiation strategies would mediate the HRM systems–performance relationship. Implications for research and managerial practices are provided.     

A re-examination of Libor rigging: a time-varying cointegration perspective

Using a time-varying cointegration framework, this paper examines the alleged manipulation of the London interbank offered rate (Libor) during the 2007–2009 financial crisis. Bank quotes are found to be poor indicators of their financing costs in the crisis period. The aberration in the estimated values of the cointegrating and error correction parameters governing the long-run equilibrium relationship between bank quotes and the final Libor suggests banks were submitting lower quotes. Further analysis which controls for an individual bank’s credit risk, market wide credit and liquidity risks, and a common market factor, demonstrate possible evidence of Libor rigging during the crisis period.
