“…We follow Eitrheim et al . (2002) and Anundsen and Nymoen (2019) and formulate the ‘saving for a rainy day’ hypothesis aswhere the saving ratio, , is approximated by the logarithms of income to consumption ratio, y t − c t , and labour income, yl t + i , is replaced by income, y t + i . An important time series property, which we shall utilize in the nested CVAR, is that the saving ratio is stationary, I (0), and thus that income and consumption are cointegrated with a coefficient equal to one when income is non‐stationary, I (1).…”
