Abstract: | The way in which cyclical fluctuations in activity in the U.K. economy affect factor income shares and the channels through which these effects work through to the size distribution of income are traced. Using National Accounts data, the impact of an upturn in activity in increasing the shares of profits and self-employment income in factor incomes, and of self-employment and rent, interest and dividends in personal incomes, is quantified. Using Family Expenditure Survey micro-data, the resulting shift in decile shares in personal income, which is towards the top of the size distribution, is estimated. |
