Wanted to double check on use of multiple currencies in one conjoint study.
We are running a single CBC across different geographies (US, UK, Ger, Aus) and would have prices in different currencies to show in each geography. To combine the results at an overall level, shall we show price in a single currency? Does this mean country wise designs or can we use conditional pricing for discrete price levels? (have a SS=30 per country)
Is there a way to estimate results at an overall level if we are showing price points in different currencies?
As mentioned, sample size limitations dictate we have 30 SS for each geography, would this be enough for country level estimation is that's the way to proceed?
What are the drawbacks of possible ways?
Would be great to hear your thoughts.
