Ella Getz Wold will be using data from the Norwegian administrative tax records on capital income and wealth stocks. The data has some nice qualities: i) it is mostly reported by third parties; ii) it covers the entire population, including the very top of the income/wealth distribution; iii) it includes financial assets, business assets and housing assets (the latter for a shorter time period); and iv) it covers a 20+ year period (so some generational analysis is possible).
