About the Book

This entertaining introduction to economics will promote financial literacy.

Sometimes prices go up and up and up. Then they suddenly crash. Why? In simple language and with colorful graphics and amusing characters, this picture book explains the basic laws of supply and demand, using examples kids will understand, such as dueling lemonade stands on the same block. Terms such as "fixed costs" and "variable costs" are clearly explained, and a glossary as well as a helpful graphic summary are included.


"In Adler's capable hands, there is life in economics yet. Adler always finds a canny way into the math game, both practical and enjoyable."—Kirkus Reviews
