Same essential problems as the SovUnion, but in the early-mid 1980s, the Polish economy was struggling.
I fail to see how limiting how much product can be bought and sold would stimulate an economy, outside of a major excess issue like the one that led to The New Deal in the USA.
You’re thinking too much in market terms. It should be more “Our allocation of production has resulted in shortages of these goods; we must figure out a way of distributing these goods without resorting to ‘highest-bidder’ style market economics.”
Typically, in market-oriented economies, this happens during wartime when the government doesn’t trust market economies (rightly) to deliver the needs of the war while there are still civilians willing to outbid the government. In command economies, this happens whenever the priorities of the government and the civilian population are at odds (such as Poland exporting most of its sugar to the SovUnion despite massive domestic demand for sugar and higher sugar production per capita than ever before).
I have a game wishlisted on Steam called Workers & Resources: Soviet Republic that I’m hoping might prove educational to better understand how that system worked because sometimes it seems so foreign to me.
