This paper investigates the causal impact of oil price fluctuations on financial markets since January 2014. Following a heteroscedasticity-based event study approach, the paper instruments changes in oil prices by exogenous shocks in oil supply. It finds that oil price declines raise...

Did unemployment in the Great Recession hurt people's health? The broad answer is no: job losses have statistically insignificant impacts on mortality. The exogenous sources of job losses in a U.S. county is the tradable job losses driven by external demand collapses during the Great Recession....

Noting that Africa's resource-rich countries have not translated their wealth into sustained economic growth and poverty reduction, this paper shows that by transferring a portion of resource-related government revenues uniformly and universally as direct payments to the population, some...

Employing a sample of voluntary CEO turnovers selected from S&P 500 firms over the period 2004-2012, we investigate the impact of the prior firm's performance on the length of time expired between when a CEO resigns and when he/she is hired for an equivalent job with a similar company. We find...

This Working Paper presents some preliminary results for a new goodness-of- t method for VARMA(p,q) models. Relations between least squares residuals and true errors are re-examined, and a new family of statistics is proposed. A new goodness-of- t process is also suggested, that can be seen as...

Policy makers around the world are increasingly recognizing the need to drastically reduce methane emissions in parallel with carbon dioxide emissions. More than a hundred countries have signed the Global Methane Pledge and made a collective commitment to reduce global methane emissions by 30%...

Enzyme catalysed hydrolysis of bio-based poly(lactic acid) (PLA) represents an environmentally-friendly route for a controlled modification of polymer fibres. In this work, the topochemical hydrolysis reaction of cutinase from Humicola insolens (HiC) on PLA fibre was mechanistically investigated...
