Economics + marketing is a solid combo for market research - especially if you genuinely enjoy both. Marketing gives you the consumer perspective, positioning, segmentation, and how go-to-market actually works. Economics sharpens your thinking on incentives, demand, pricing, and competition. But here's the thing from running enough experiments and analysis campaigns: the double major alone won't set you apart. what really makes you competitive is the quantitative toolkit.
If you can, pile on stats, research methods, survey design, and econometrics. Learn Excel, SQL, Python or R, Tableau/Power BI - and SPSS if your uni offers it. Market research is a blend of understanding people and proving things with data. Your majors cover the first part well, you've got to deliberately build the second.
Also, start doing real projects early. Analyse survey data, write a consumer insights report, study a brand or category, or run a small research project for a club or local business. Two or three solid portfolio pieces will carry more weight than the exact name of your degree. So yes, good choice - but pair it with stats, data skills, and practical work. That's where the edge lives
