such imports even when relations became more tense from 1933 to 1937. Four and Five Year Plans Both the German Four Year Plan and Soviet Second and Third Five Year Plans emphasized the construction of military installations, factories, canals, roads and cities that produced accumulating crises' of over-investment and supply failures in other non-emphasized economic areas. Monopsony compromised both systems, with the Soviet state the principal purchaser for all goods in its economy, while the German state was the largest purchaser in its economy. German cost-plus contracts and Soviet fraud and mismanagement caused inefficient contracting, resulting in the building of massive contract-monitoring bureaucratic structures that produced additional costs in both economies. In March 1939, the Soviet Union announced the new directives of the Third Five Year Plan, named "Five Year Plan of Special Steels and Chemicals." The defense sector received the highest priority under the plan. The pressure to fulfill Soviet Second and Third Five Year Plan goals was more keen where managers faced the risk that every failure might be interpreted as an act of economic sabotage. In 1936, the head of the Soviet Gosbank was shot after he suggested a relaxation of economic controls. To cope with state controls of supply systems, blat (informal black market) agreements were often made, which could not easily be tracked by Gosplan. Hitler's Four Year Plan called for a modernized expanded agricultural sector to free Germany from the fear of a blockade, a network of motorways, remodeled cities, a massive program of import-substitution to supply synthetic strategic material and military industries capable of out-producing the largest enemy economy. The plan required a rigid structure of six main economic divisions: raw materials production, raw materials distribution, labor agriculture, price control and foreign exchange. It made heavy demands on resources already in short supply because of high military spending, resulting in the delay or postponement of most programs while scrambling for raw materials, building workers and engineering equipment. Pseudo markets were created to attempt to make the system work more efficiently. In response to blat-like commerce arising, Germany passed laws labeling such unsanctioned commerce as "economic sabotage" punishable by death. German regulation of private property and capital movement hardened, and property could be seized from political enemies such as ethnic Jews or communists.
