A: The common notation for the "intercept" term of an equation specified as Y = a + bX. Mathematically, the a-intercept term indicates the value of the Y variable when the value of the X variable is equal to zero. Theoretically, the a-intercept is frequently used to indicate exogenous or independent influences on the Y variable, that is, influences that are independent of the X variable. For example, if Y represents consumption and X represents national income, a measures autonomous consumption expenditures.

PRICE LEVEL The average of the prices of goods and services produced in the aggregate economy. In a theoretical sense, the price level is the price of aggregate production. In a practical sense, the price level is commonly measured by either of two price indexes, the Consumer Price Index (CPI) or the GDP price deflator. The CPI is the price index widely publicized in the media and used by the general public. The GDP price deflator, in contrast, is less well-known, but is usually the price index of choice among economists. The inflation rate is calculated as the percentage change in the price level.

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.
