Commonality in liquidity: An empirical examination of emerging order-driven equity and derivatives market

Using a sample of actively traded stocks and options from emerging order-driven market, this study examines and provides satisfactory evidence for the existence of commonality in liquidity for both spot and derivatives market. For equities, the market- and industry-wide commonality remain strong even after controlling for market returns and individual firm volatility and for options after accounting for the underlying stock market liquidity and implied volatility. Compared to the stock market, options market exhibit an increased commonality in liquidity with market capitalization. Here, information asymmetry acts as an important microstructure related source of commonality in liquidity across markets. The findings are robust across call and put options with negligible evidence of cross-sectional error correlation for all the liquidity measures

Block-ownership structure, bank nominee director and crash-risk

We study the effect of outside block-ownership on the future firm-specific crash-risk of Indian firms. Major and dedicated block-owners play a significant role in aggravating the firm’s susceptibility towards crash-risk. Within a novel regulatory setup in India, where borrowing firms are entitled to a bank nominated board-member, we find an ancillary influence of bank nominee’s presence in dissipating block-owners influence on firm-level crash-risk. These results support the monitoring hypothesis in alleviating future firm-level crash-risk. Our results are robust to alternate model specifications, different crash-risk and block-ownership measures, clustering, and an array of control variables

The CMS Outer Hadron Calorimeter

The CMS hadron calorimeter is a sampling calorimeter with brass absorber and plastic scintillator tiles with wavelength shifting fibres for carrying the light to the readout device. The barrel hadron calorimeter is complemented with a outer calorimeter to ensure high energy shower containment in CMS and thus working as a tail catcher. Fabrication, testing and calibrations of the outer hadron calorimeter are carried out keeping in mind its importance in the energy measurement of jets in view of linearity and resolution. It will provide a net improvement in missing \et measurements at LHC energies. The outer hadron calorimeter has a very good signal to background ratio even for a minimum ionising particle and can hence be used in coincidence with the Resistive Plate Chambers of the CMS detector for the muon trigger
