Shariah compliance and corporate cash holdings

This study investigates the influence of Shariah compliance status on cash holding levels and the speed of adjustment of non-financial listed firms in six Gulf Cooperation countries from 2005 to 2016. The results show that Shariah compliance status has a significant effect on firms’ cash holding decisions. Shariah-compliant firms have significantly higher cash holding levels than non-Shariah-compliant firms. Further, Shariah-compliant firms adjust more quickly towards their target cash holdings than their conventional counterparts. In our view, Shariah-compliant firms are subject to multiple restrictions that limit their external financing channels. Therefore, holding larger cash reserves is important as it helps gain from the transaction cost motive of holding cash. The findings of this study have important implications for regulators, investors and managers. To the best of our knowledge, this study is the first to compare the effect of Shariah compliance on firms’ cash holdings and the speed of adjustment towards the trade-off theory’s optimal cash holding target.     

Employment protection and leverage adjustment speed: Evidence from China

Stricter employment protection may affect capital structure adjustment speed in two ways. First, it may increase the cost of capital and decrease the leverage adjustment speed. Second, it increases financing needs and capital adjustment speed. Using China's 2008 Labor Contract Law as a natural experiment and the PSM-DID methodology, we find that the latter effect dominates the former. Specifically, stricter employment protection increases leverage adjustment speed, and this effect is more pronounced for non-state-owned firms and firms with larger leverage deviations. Furthermore, transmission channel tests show that employment protection increases firms’ substitution of labor with capital, driving up investment and financing needs. Finally, the increased leverage adjustment speed induced by enhanced employment protection is beneficial to firm performance.     

The expectations hypothesis and decoupling of short- and long-term US interest rates: A pairwise approach

The link between short-term policy rates and long-term rates elucidate the potential effectiveness of monetary policy. We examine the US term structure of interest rates using a pairwise econometric approach advocated by Pesaran (2007). Our empirical modelling strategy employs a probabilistic test statistic for the expectations hypothesis of the term structure based on the percentage of unit root rejections among all interest rate differentials. We find support for the expectations hypothesis and provide new insights into the nature of interest rate decoupling which are of value to policymakers. The maturity gap associated with interest rate pairs negatively impacts on the probability of stationarity, and also on the speed of adjustment towards long-run equilibrium. We further show that the speed of adjustment has become more sensitive to the maturity gap over time.     

Is the monetary policy rule responsive to exchange rate changes? The case of Indonesia,Malaysia, the Philippines,and Thailand

Extending Obstfeld and Rogoff (J Econ Perspect 9:73–96, 1995), Ball (Monetary policy rules, University of Chicago Press, pp. 127–144, 1999), Svensson (J Int Econ 50: 155–183, 2000), Taylor (Am Econ Rev 91: 263–267, 2001), Gali and Gertler (J Econ Perspect 21:25–46, 2007), and others, this paper finds that central banks in the Philippines and Thailand respond negatively to the current real exchange rate and positively to the lagged real exchange rate whereas central banks in Indonesia and Malaysia do not react to the current or lagged real exchange rate. For the Philippines and Thailand, the null hypothesis that the sum of the coefficients of the current and lagged real exchange rates is zero cannot be rejected at the 5% level. Central banks in these four countries respond positively to the inflation rate and the output gap, suggesting that the concept of a simple or an extended Taylor rule would apply to these countries. Monetary policy reaction functions for Indonesia and Thailand are steeper than those for Malaysia and the Philippines and would be more responsive to a change in the inflation rate.      

Multifaceted effects of host country language proficiency in expatriate cross-cultural adjustments: a qualitative study in China

While expatriates often face language barriers in host countries, relatively little research has focused on the influence of host country language proficiency on cross-cultural adjustment. We drew on social identity theory and conducted an interview-based study with 70 expatriates and their host country national (HCN) colleagues to provide a contextual account of host country language proficiency's effects on work and non-work-related adjustment in China. Our findings suggest that expatriate host country language proficiency has multifaceted effects on expatriates' HCN interaction, social support, and network-related work and non-work adjustment.

Calibration of implied volatility for the exchange rate for the Chinese Yuan from its derivatives

Revised implied volatility curves and surfaces for the Chinese Yuan (CNY) exchange rate are obtained from market quotations for CNY non-deliverable options by solving an inverse problem of foreign exchange option pricing, which is calculated using a regularization approach in an optimal control framework. To take account of the market expectation for the CNY exchange rate, a stochastic adjusted factor is applied that follows a Vasicek model with parameters fitted from market quotations for CNY non-deliverable forwards. A well-posed numerical scheme is implemented.     

从增量扩张到存量调整的国土空间规划模式转变研究——基于珠三角高强度开发地区的实践探索

研究目的：基于珠三角等存量地区当下规划管理面临的困境,探讨增量扩张与存量调整两种导向下规划模式的差异,为生态文明时代存量调整型规划的编制与实施提供参考。研究方法：文献研究法和案例归纳法。研究结果：（1）在存量地区,传统的规划管理模式与内涵式优化、市场配置资源、多元主体治理等空间逻辑不相适应渐渐显现;（2）珠三角作为高强度开发典型地区,规划模式正发生从“增量扩张”到“存量调整”的转变,在规划编制各环节关注土地产权与土地价值协调,将规划与土地管理相融合,在推动存量调整优化中注重全链条政策支撑;（3）提出在“总体规划—专项规划—详细规划”的体系内推动存量空间调整的规划策略,形成“时空统筹+空间腾挪+土地连片整备+权益价值再平衡”等促进存量调整实施的政策支撑机制。研究结论：生态文明时代,以存量调整为主的高强度开发地区需把握建立国土空间规划体系的契机,探索动态治理的存量调整型国土空间规划模式,在编制和实施中关注规划对空间权益的分配与再分配及土地价值再平衡,重视存量空间调整实施过程中政策机制的支撑与保障。

ARBITRAGE‐FREE BILATERAL COUNTERPARTY RISK VALUATION UNDER COLLATERALIZATION AND APPLICATION TO CREDIT DEFAULT SWAPS

We develop an arbitrage‐free valuation framework for bilateral counterparty risk, where collateral is included with possible rehypothecation. We show that the adjustment is given by the sum of two option payoff terms, where each term depends on the netted exposure, i.e., the difference between the on‐default exposure and the predefault collateral account. We then specialize our analysis to credit default swaps (CDS) as underlying portfolios, and construct a numerical scheme to evaluate the adjustment under a doubly stochastic default framework. In particular, we show that for CDS contracts a perfect collateralization cannot be achieved, even under continuous collateralization, if the reference entity’s and counterparty’s default times are dependent. The impact of rehypothecation, collateral margining frequency, and default correlation‐induced contagion is illustrated with numerical examples.
