The household debt is and will always be an interesting parameter for economists. And can it possibly get more interesting than by comparing one of the world's economic giants with hundreds of million citizens to a small Scandinavian country with just ten million citizens? In this study we examine the household debt in the United States of America and Sweden. We test whether the two nations have some similar and/or different denominators that drives the household debt. We hand-picked four different variables that we believed would have an impact on the household debt and ran an error-correction model to execute the tests. The four explanatory variables that we choose are: Federal fund rate, disposable income, indexed houseprices and the number of citizens in the age of 15-64. The results we got tells us that there seems to be differences between the countries. Our ECM regressions showed results that differs between the countries while the OLS-model had more similar results and the OLS also had r2-values around 50 % which indicates that we might have found some variables that actually have some influence on the debt ratio. We have presented our expectations regarding how we think each variable will influence the debt ratio. After running the regressions it turned out that we were on the right track since most of our expectations were successfully fulfilled.
