Budget Set

A budget set or opportunity set includes all possible consumption bundles that someone can afford given the prices of goods and the person's income level. The budget set is bounded above by the budget line. Graphically speaking, all the consumption bundles that lie inside the budget constraint and on the budget constraint form the budget set or opportunity set.

By most definitions, budget sets must be compact and convex.

Famous quotes containing the words budget and/or set:

“We might come closer to balancing the Budget if all of us lived closer to the Commandments and the Golden Rule.”
—Ronald Reagan (b. 1911)

“Time doth transfix the flourish set on youth
And delves the parallels in beauty’s brow,
Feeds on the rarities of nature’s truth,
And nothing stands but for his scythe to mow:
And yet to times in hope my verse shall stand,
Praising thy worth, despite his cruel hand.”
—William Shakespeare (1564–1616)
