Competitive Little Lads and Ladies is the second book in a series to aid in teaching economic concepts to children from 1st-4th grades. The story is about several neighborhood kids who wish to buy new toys and want to mimic the hero Gabriel David from the first book, Supply and Demand and the Lemonade Stand. Each tries different approaches, prices, products, and ways of competing to earn their money. The book is written at an accessible level, and it is encouraged to be used in grade school classrooms where economics is a part of the curriculum. There are two companion books as well - Supply and Demand and the Lemonade Stand, and Opportunity Cost and the Mystery of the Left Socks Lost.
