From 1926 to 1929 he was executive editor of the journal On the Agrarian Front and a member of the editorial board of the journal Problems of Economy as well as a member of the editorial board of the Great Soviet Encyclopedia. He was also the editor of the Economic Encyclopedia. Kritzman wrote many books and polemics and socialist construction as well as criticisms of non-Marxist political economy.
He staunchly opposed the theory of Alexander Chayanov and the family labor school. He fought for the justification of the three-tier scheme of differentiation of the peasantry (poor peasant -middle peasant - kulak), which became one of the foundations of the dekulakization policy in 1929–1933.
Hardly any information is available about Krizman's last years, which apparently were largely spent on private studies. In Soviet and Russian publications, it is usually noted that he succumbed to kidney disease in June 1938.[2] On the other hand, some recent publications from English speaking sources[3] claim that Krizman fell victim to the Great Purge, however there isn't any evidence to support this.[4] His death is sometimes dated to have happened in June 1937. An obituary in connection with his death was signed by Eugene Varga, Abram Deborin, Gleb Krzhizhanovsky and Stanislav Strumilin.[5]
