We examine the market-place work of high school seniors and their academic success. In particular, we examine the relationship between allowance and hours of high school work. Then, we relate the effect of market-place work to academic achievement. Our results indicate that allowance is a significant determinant of high school work hours, having a negative effect. Further, we find that high school work reduces academic success by reducing the probability of being an honors student. Our results are important because they expand our understanding of high school work behavior and its consequences. (Contains 3 tables and 11 notes.)
