Suppose that consumers' preferences are well behaved in that properties 4-1 to 4-4 (completeness, more is better, diminishing marginal rate of substitution, and transitivity) are satisfied. Furthermore, assume goods X and Y are normal goods and the price of good X decreases. Then the substitution effect will lead consumers to consume O less of good X and more of good Y. more of good X and less of good Y. O more of good X and more of good Y. less of good X and less of good Y
