MARGINAL PROPENSITY TO INVEST: The proportion of each additional dollar of national income that is used for investment expenditures. Or alternatively, this is the change in investment expenditures due to a change in national income. Abbreviated MPI, the marginal propensity to invest is the slope of the investment line used in the analysis of Keynesian economics. As such, it also plays a role in the slope of the aggregate expenditure line and the multiplier effect.

BROWN PRAGMATOX
Your compete MICRO*scope for today
You are the type of person who doesn't place a particularly high value on frivolous things, like matching socks. Family and friends never, never, never try to convince you of an alternative point of view, political or otherwise. Today, you are likely to spend a great deal of time surfing the Internet hoping to buy either a birthday gift for your father that doesn't look like every other birthday gift for your father or a green fountain pen. Be on the lookout for broken fingernail clippers. You should consider shopping at stores or businesses beginning with the letter W, but do not buy any products with a serial number or product code containing the number 990297. Your preferred shopping venue is thrift stores. Your special symbol is the comma (,).
Is this You?
As a Brown Pragmatox, you are down-to-earth and practical. You are hard working and industrious. You are frugal to the point that you might even refrain from making a purchase that you really, really need. Doing so often causes problems down the road. You definitely go with function over form and substance over style.
This isn't me! What am I?

AVERAGE REVENUE AND MARGINAL REVENUE A mathematical connection between average revenue and marginal revenue stating that the change in the average revenue depends on a comparison between average revenue and marginal revenue. For perfect competition, with no market control, marginal revenue is equal to average revenue, and average revenue does not change. For monopoly and other firms with market control, marginal revenue is less than average revenue, and average revenue falls.

Gambling On A State LOTTERYYou might recall during our discussion of gambling in the entry appropriately titled gambling, that I purchased $5 worth of Super Luck-O Multi-State Lottery tickets at the Master's Sprocket convenience store. Well, the day of the big drawing came and went. I was about as close to winning as the planet Pluto is to buying a Hot Mamma Fudge Bananarama Ice Cream Sundae on a cold winter morning. At least the five dollars I paid for lottery tickets goes to a good cause. The state uses a share of the proceeds for education, and that keeps my taxes lower. If you'll excuse me for a moment, I've got another ten bucks in my pocket screaming for the chance to by some more Super Luck-O Multi-State Lottery tickets. While I'm doing that, why don't you see if this is a wise consumption move on my part.
