What drives the liquidity premium in the Chinese stock market?

This paper examines the dynamics of the liquidity premium in the Chinese stock market by adopting a multivariate decomposition approach to measure the individual contributions of various driving forces of the premium (such as firm size, idiosyncratic volatility, and market liquidity betas). By employing a wide range of liquidity measures, we show that liquidity premium is generally significant in the Chinese stock market. Furthermore, this premium is increasing in recent years starting from 2011; this observation is different from the United States market, in which the premium has declined over the years. Moreover, the multivariate decomposition approach highlights several asset pricing factors as the main driving forces of the premium. Based on the Amihud liquidity measure, the decomposition approach indicates that the size factor contributes 45–65% to the liquidity premium. However, the measure based on turnover suggests that idiosyncratic volatility accounts for at least 60% of the liquidity premium. In contrast, the global market liquidity beta does not significantly contribute to the premium. However, there is some evidence that the local market liquidity beta has become more significant in its impact on the premium during the period from 2011 to 2015. Our results imply that the findings on the liquidity premium in the Chinese stock market could be sensitive to the liquidity measure used and period of analysis.     

Liquidity and firm value in an emerging market: Nonlinearity,political connections and corporate ownership

This study re-examines the relationship between liquidity and firm value in the emerging stock market of Malaysia, exploring the issues of nonlinearity and moderating variables. Using data for all non-financial firms traded on Bursa Malaysia over the sample period of 2000–2015, the results from the baseline quadratic model suggest stocks must be traded higher than the threshold liquidity level before reaping the benefit of larger firm value. Our key finding of a nonlinear relationship remains robust to alternative liquidity measures and estimation methods, as well as passing a series of endogeneity checks. Using an ideal candidate of lot size reduction for Malaysian stocks in May 2003 as exogenous liquidity shock, we establish the causal effect from liquidity to firm value. Further interaction analyses uncover three important moderating variables in the liquidity-firm value relationship, in which the value impact demands a more liquid market for Malaysian public firms with political connections, higher foreign nominee ownership and higher foreign institutional ownership.     

Effects of the short sale circuit breaker on the stock market

We provide new evidence on the effects of the recently introduced short sale circuit breaker, Rule 201, which triggers when the price of a stock drops more than 10 percent in a single day. The regulatory presumption is that the trigger should damper intraday price declines for affected stocks. However, our evidence suggests that this is not the case. The circuit breaker fails to reduce intraday volatility and intraday price declines, especially for the most volatile stocks in the market. Market quality measures based on liquidity and pricing efficiency are largely unaffected. Higher dispersion of investor opinion increases overpricing when the circuit breaker is in force. Price stabilization after stocks trigger the circuit breaker is shown for stocks that experience substantial price declines. Finally, post‐shock drift reduction is consistent with improved informational efficiency.     

Derivatives pricing with liquidity risk

This paper develops a novel, general derivative pricing model which introduces a liquidity risk factor. The model variants we outline offer a sufficient degree of flexibility so as to enable the valuation of various types of derivative classes including futures, American options, and mortgage backed security options, whereas existing derivative models can only price liquidity risk in European derivatives. We validate the model with oil and gold futures data and compare it to a classical benchmark model void of any liquidity risk. We find that our model is significantly more accurate than the classical model for pricing both oil and gold contracts.     

Sharing contracts' marginalisation,adverse selection and markup calculation

This paper proposes a new approach to explain the dominance—in the Islamic banking market—of markup contracts at the expense of sharing ones. We show that the dual pricing practised in this market produces an additional—or artificial—dimension of adverse selection, which is causing the sharing contracts' marginalization. We suggest specialized use of two Islamic contractual categories as a device for eliminating artificial adverse selection. We suggest also an endogenous calculation of the markup, that is independent of the interest rate, based on the financing cost unification. This approach allows the deduction of default and liquidity risk premiums.     

Implicit transaction cost management using intraday price dynamics

Using the Exchange Liquidity Measure, we show that implicit transaction costs exhibit intraday regularities around specific price change signals for a sample of European blue chips publicly quoted on Euronext. Not only transaction costs follow a reverse J-shape throughout the day but they also decrease significantly around specific patterns of price dynamics. By focusing on these signals during the trading day, liquidity traders may detect intraday windows of opportunities during which implicit transaction costs are lower.     

Stock liquidity and firm value: evidence from China

Empirical evidence for the effect of stock liquidity on firm value is limited and mixed due to a severe endogeneity problem. This article adds to the literature on this topic by providing new empirical evidence using the nontradable share reform in China as a quasi-natural experiment. Our results show that higher stock liquidity can lead to significant firm value improvement.     

An evaluation of alternative approaches to the application of cash reserve requirements in Nigeria

This article evaluated ‘o-size-fits-all’ approach to cash reserve requirement implementation in Nigeria using the Vector Autoregressive methodology and scenario analysis. The central thrust was to ascertain if a one-size-fits-all approach would produce a better outcome or perhaps utilizing a differentiated approach would provide a better outcome. To that effect, our results eloquently provides various scenarios for consideration.     

Quantitative Analysis of the COVID-19 Pandemic Shock to Household Consumption in China

We study the impact of the COVID-19 pandemic shock on household consumption in China. Using household survey data, we find that the proportion of liquidity-constrained households increases quickly, but the constraint levels vary across distinct groups. We build a heterogeneous agent life cycle incomplete market model to analyze the long-run and short-run effects of the pandemic shock. The quantitative results reveal a slow recovery of consumption due to three reasons: hiking unemployment rate, declining labor productivity, and worsening income stability. The hiking unemployment rate plays the key role in households’ consumption reduction since it simultaneously leads to a negative income effect and upsurging precautionary saving motives. Our paper highlights the importance of maintaining a stable labor market for faster recovery.
