ABSTRACT
The aim of this study is to empirically analyze the impact of corporate governance on stock liquidity and the moderating role of financial transparency, through the lens of information asymmetry and agency theory. The sample consists of non-financial firms listed on the Pakistan stock exchange during the 2009-2019 period. The study used an instrumental variable approach and new corporate governance index, developed with principal component analysis, to demonstrate a relationship between corporate governance and stock liquidity. The results show a significant, positive relationship between the corporate governance index and stock liquidity, suggesting that well governed firms have high liquidity. To the best of our knowledge, this is the first finance study to investigate the moderating impact of financial transparency on the relation between corporate governance and stock liquidity. The results show that financial transparency, as measured by multiple proxies, has a negative moderating impact on the relationship between corporate governance and stock liquidity, suggesting that corporate governance in Pakistan is weak. Together, the results suggest that Pakistani firms use financial transparency as a substitute for corporate governance to improve stock liquidity. The results are robust to a series of endogeneity checks using alternative proxies of stock liquidity.
ABSTRACT
The study analyzes the impact of ownership structure on dividend smoothing via the lens of agency and information asymmetry theory. The study also investigates the impact of ownership on dividend smoothing in the unexamined asymmetric context Dividend smoothing is measured via speed of adjustment and relative volatility. The study documents that higher individual, management, and institutional ownerships are positively associated with increased dividend smoothing. Consistent with the rental hypothesis in foreign-owned firms smooth less also concentrated firms bear with cuts and omissions. Foreign ownership has the opposite impact on dividend smoothing in adjusting dividends from below and above i.e., always prefer high dividends. Individual ownership has also exhibited a different impact in smoothing from below and above. Institutional owners avoid cuts and omissions and negatively affect SOA (smooth more) in case of adjusting dividends from above. Ownership concentration is negatively associated with dividend smoothing irrespective of whether the firm is smoothing from above or below. In contrast, management ownership negatively affected SOA in adjusting from above or below. Family firms in Pakistan smooth more to win minor shareholders' trust and signal that they sacrifice their private benefits to reduce the type II agency problem. Finally, the authors found a negative association between dividend smoothing and corporate governance quality. Over all the findings of the current study provides insight to the investors and regulators by offering dividend smoothing as an alternative monitoring mechanism to corporate governance.
ABSTRACT
The main aim of this study was to empirically analyze whether Institutional Quality moderates the relationship between corporate governance and stock liquidity through the light of agency and information asymmetry theory. To the best of our knowledge, this is the first finance study. The sample consists of 230 non-financial firms listed on the Pakistan stock exchange during the period of 2009-2019. We used an instrumental variable approach and our new Institutional Quality index composed of world governance indicators and a corporate governance index, developed via principal component analysis, to demonstrate a relationship between corporate governance and stock liquidity and check the moderating role of Institutional Quality by following the resources complementary phenomenon. Our results show a significant, positive relationship between the corporate governance index and stock liquidity, suggesting that well-governed firms have high liquidity. The results show that the Institutional Quality index has a positive moderating impact on the relationship between corporate governance and stock liquidity, suggesting that corporate governance in Pakistan is weak. Our results are robust to a series of endogeneity checks using alternative proxies of stock liquidity.
ABSTRACT
Currently praziquantel is one of the major drugs used in treatment of schistosomiasis and other trematode infections.Recent experimental studies indicate that a new anthelmintic,tribendimidine,is used in the treatment of intestinal nematodes,also possesses effect against several species of trematodes including Clonorchis sinensis,Opisthorchis viverrini and Echinostoma caproni.Tribendimidine is even more effective against C.sinensis in rats that a single 300 mg/kg oral dose cures almost all of the animals treated,a lower cure dose than praziquantel(375-500 mg/kg).The anti-malarial drugs artemether and artesunate are not only effective in the prevention of schistosomiasis,but also effective against several species of trematodes,especially C.sinensis.The single oral dose of both drugs to cure or achieve high efficacy in infected rats is 75 mg/kg.This review summarized research progress on tribendimidine,artesunate,and artemether in experimental animals infected with C.sinensis and other species of trematodes.
