I have to pick a research topic for my master thesis. I'm studying sustainable finance and was thinking about researching the effect of esg-scores on cost of capital of sin stocks. This would be heavily influenced by the price of sin, but there is not enough data available. Does anyone have an idea for this?
I also proposed the effect of the COVID-19 pandemic on alternative investment compared to normal investments, but my supervisor said those results would be insignificant as the market has been all over the place.
