It’s tricky to know where to start but I’d recommend searching for papers by Andrew Clark on Google Scholar. Then you can read other referenced studies if interested etc.
What you are looking for here are studies looking at the relationship between income and subjective well-being (sometimes shortened to SWB). This is the general term for self reported measures of well-being, though of course this can be broken down further into more detailed factors such as affective (how are you right now) and cognitive (how satisfied you are with your life overall).
