Economics vs computer science

Which degree has better job prospects and salary. I have read that a computer science degree can get you the same jobs in finance as economics, to what extent is this true?

Technically Economics, but you are talking about averages over a significant number of people, and your personal employability chances are not really influenced by your degree.

For most finance roles you could have studied any subject, it could be History of Arts and you’d have the same basic application as an Economics or Computer Science grad. Some finance roles do require you to have a high level of mathematic content to your degree though, and so that is where an Economics degree might help - but as an Economics graduate with very little mathematics to their degree, I can tell you that isn’t always the case either!

Only if you did a high level of maths content in your economics degree, then you could be:

An actuary
An economist
A statistician

Could you give me examples of jobs that I would be able to apply for with an economics degree but not with a computer degree?

There's not many but...Economist?

It works both ways though. Both degrees are numerate and so similar jobs are available to both. Very few jobs where you need a CS degree as well - even for something like programming it's not necessary.

Computer science is slowly becoming a very saturated degree, not to mention that there's people who do it a lot better in third-world countries who are likely to steal any employment prospects a lot of graduates will be looking for.
