Actions in phygital space: Work solidarity and collective action among app-based cab drivers in India

Shalini Parth, Dharma Raju Bathini, and George Kandathil

New Technology, Work and Employment

This study delineates the microprocesses of solidarity development and the subsequent collective actions of gig workers in India amidst multiple structural constraints. Using netnography, semi-structured interviews and direct observation, we show how digitally naive app-based cab drivers amalgamate physical and digital spaces, construct a phygital space free of managerial gaze and leverage it to bond and bridge, create webs of care and share and resist multiple oppressive forces, individually and collectively. Thus, we broaden the conceptualisation of worker agency beyond labour-management antagonism and extend the extant literature on solidarity development and resistance in gig work by identifying a spatial enabler, phygital free space and the expansive role of relationship-based commitment. Relationship-based commitment not only functions as a membership mobiliser but also helps mobilise collective resistance when interwoven with an external threat-based identity created through injustice framing.

The impact of COVID-19 on tail risk: Evidence from Nifty index options

Sobhesh Kumar Agarwalla, Jayanth R. Varma, and Vineet Virmani

Economic Letters

We investigate the impact of COVID-19 using multiple forward-looking measures of uncertainty in Indian stock markets using liquid Nifty index options. The WHO declaration of COVID-19 as a pandemic coincides with a sharp rise in all measures of uncertainty considered, including option-implied volatility smiles, risk-neutral density, skewness, and kurtosis. We find that while subsequent government-imposed lockdowns and monetary easing induced a near-normalization of skewness and kurtosis, the volatility level remained elevated, demonstrating the importance of higher moments in capturing uncertainty during a pandemic. Structural breaks identified using the Bai–Perron methodology closely track the dates of significant announcements or interventions.
