what is the guns and butter curve 
the guns and butter curve is the classic economic example of the production possibility curve which demonstrates the idea of opportunity cost in a theoretical economy with only two goods a choice must be made between how much of each good to produce as an economy produces more guns military spending it must reduce its production of butter food and vice versa understanding the guns and butter curvein the chart the curve represents all possible choices of production for the economy the dots represent two possible choices of outputs the point here is that every choice has an opportunity cost you can get more of something only by giving up something else also you ll notice that the curve is the limit of production you cannot produce outside the curve unless there is an increase in productivity though the curve is meant to show a strict divide between only two options production for military spending or food it can also represent spending on military personnel equipment and operations versus all nonmilitary spending in an economy this can include investments in domestic needs such as healthcare education utilities and other services guns and butter curve as a tradeoffthe guns and butter curve charts the tradeoff that occurs within the limits of production in a given economy money spent on the development and manufacture of jet fighters for example cannot be invested in critical infrastructure repairs such as the replacement of aging bridges if a nation chooses to focus on military buildup the only way for its domestic production needs to be met is through an overall elevation of production or productivity such an increase would allow for nonmilitary products to increase even as the military buildup was underway however such gains in economic production often mean the size and scope of military production would escalate in turn maintaining such elevated production in order to meet both needs can prove to be taxing on an economy potentially leading to capital drain in other areas that are necessary to maintain a productive economy for example research and development may see less investment if all the priority is given to current production the guns and butter curve shows the correlations that link government strategy investment and production guns and butter and market forcesthe constraints of the guns and butter curve can be used to illustrate the strain put on cold war era nations that focused on military buildup while consumer goods suffered in response sustained pressure to fulfill military needs for defense was a contributing factor in the dissolution of the former soviet union which experienced shortages on food houses and other domestic necessities part of the issue was the concerted effort to keep up with defense spending in the united states in order for the domestic needs of the citizens to be fully met the soviet union needed to escalate its overall production and it productivity one issue faced by the soviet union is that the decisions for production quotas were centralized whereas many parts of the u s economy were primarily driven by market forces rather than government planning while market forces can be capricious they are far faster at giving signals and allocating capital than a bureaucratic framework the innovations and productivity growth in the wider u s economy during the cold war era generated the wealth and revenue for the u s government to undertake a program of massive military spending without growth however the guns and butter curve represents a barrier that curtails the military ambitions of most nations via the threat of civil unrest when people don t have enough to eat there are of course exceptions to the idea that a military focused government would eventually be overthrown the ruling party of north korea for example continued to spend large amounts on weaponry and its standing military even during a period of severe famine and it continues to do so today despite widespread issues with malnutrition
