To quote Barnett (2006), the Slutsky effect, as understood by most economists, is the following:
If the variables that were taken to represent business cycles were moving averages of past determining quantities that were not serially correlated – either real-world moving averages or artificially generated moving averages – then the variables of interest would become serially correlated, and this process would produce a periodicity approaching that of sine waves.
I wrote a short note using SageTeX demonstrating the effect, closely following Royoma’s book.
