If you work in the financial industry, you are used to working long hours. Particularly in investment banking, working long hours seems a badge of honour, though I always wonder if working long hours creates that much more output. Hard for me to say since I don’t work in investment banking, but there is at least a possibility to check the relationship between hours worked and output generated across countries using macroeconomics. The chart below shows the GDP per capita in 2020 for a set of high- and middle-income countries. GDP per capita is used here as the national income per person in different countries. I put this in contrast with the average number of hours worked per person in a year. I removed commodity-rich countries like Saudi Arabia or Norway because their GDP per capita is heavily distorted by the revenues from commodity exports (though I did leave Australia in the chart).
