Most information in the Soviet economy flowed from the top down. There were several mechanisms in place for producers and consumers to provide input and information that would help in the drafting of economic plans (as detailed below), but the political climate was such that few people ever provided negative input or criticism of the plan. Thus, Soviet planners had very little reliable feedback that they could use to determine the success of their plans. This meant that economic planning was often done based on faulty or outdated information, particularly in sectors with large numbers of consumers. As a result, some goods tended to be underproduced, leading to shortages, while other goods were overproduced and accumulated in storage.
