CHANGE IN AGGREGATE DEMAND: A shift of the aggregate demand curve caused by a change in one of the aggregate demand determinants. In essence, a change in aggregate demand is caused by any factor affecting aggregate demand EXCEPT the price level. This concept should be contrasted directly with a change in aggregate expenditures. You might also want to review the terms change in quantity demanded and change in demand, as well. The change in aggregate demand is comparable to the change in market demand. A change in aggregate demand is a change in ALL price level-aggregate expenditure combinations, meaning that each price level is matched up with a different aggregate expenditure (which is illustrated as a shift of the aggregate demand curve). This change in aggregate demand is caused by a change in any of the aggregate demand determinants. In contrast, a change in aggregate expenditures is a change from one price level-aggregate expenditure combination to the another (which is illustrated as a movement along a given aggregate demand curve).

MARGINAL PRODUCT The change in the quantity of total product resulting from a unit change in a variable input, keeping all other inputs unchanged. Marginal product, usually abbreviated MP, is found by dividing the change in total product by the change in the variable input. Marginal product, which occasionally goes by the alias marginal physical product (MPP), is one of two measures derived from total product. The other is average product.

Keeping The Lid On INFLATIONIt's Thursday! It's 2:30 in the afternoon! IT'S PRETZEL TIME!! We must make a brief stop at one of Shady Valley's most acclaimed business establishments -- Max Mulroney's Pretzel Haven. My favorite, of course, is pretzel-on-a-stick. An ample supply of barbecue sauce is standard fair. I'm taken aback! Max has raised his pretzel prices once again -- for the third Thursday in a row. What sort of chicanery is at work here? Is Max trying to gouge the pretzel lovers of Shady Valley? Max says, quite emphatically, NO! His pretzel producing cost has risen. It seems, he explains, to be a pervasive problem throughout Shady Valley. He's not alone in pumping up prices. A quick price checking, window shopping expedition through the Shady Valley Central Town Sprawling Hills Shopping Mall, Mega-Mart Discount Warehouse Super Center, Manny Mustard's House of Sandwiches, and even Dr. Nova Cain's dental office reveals truth to Max's claim. Prices all over Shady Valley are rising. I suspect that there's only one way to unravel the intricacies of this mystery, we're need to examine the topic of inflation.
