  1. The Accounting Rookie Job Market: A Practitioner's Guide

    Ethan Rouen

    This paper offers guidance and shares collective wisdom for accounting Ph.D. students who will be entering the academic job market. It is divided into two sections. The first offers subjective advice on the dissertation process—from choosing a topic to surviving the inevitable self-doubt—from my personal experience and the experiences of other former job candidates. The second section focuses mainly on factual components of the job market, providing details that will be useful to candidates before they begin the search. It concludes with subjective advice on how to make the job hunt more enjoyable. Both sections are organized chronologically and attempt to be comprehensive, beginning with choosing a dissertation topic and adviser, and concluding with the decision to accept an offer.

  2. The Role of Taxes in the Disconnect Between Corporate Performance and Economic Growth

    Urooj Khan, Suresh Nallareddy and Ethan Rouen

    We investigate the relation between the growth in corporate profits and the overall U.S. economy, focusing on the impact of the U.S. corporate tax regime on this relation. We document that the growth of corporate profits, on average, has outpaced the growth of the economy, and this disconnect increases as the difference between the corporate income tax rate of the U.S. and the other OECD countries increases. The underlying mechanism is fewer corporate profits being channeled into subsequent domestic investments when the U.S. tax rate is relatively higher, leading to lower economic growth. Our findings have implications for policy setters.

  3. Rethinking Measurement of Pay Disparity and its Relation to Firm Performance

    Ethan Rouen

    I develop measures of firm-level pay disparity and examine their relation to firm accounting performance. Using comprehensive compensation data for a large sample of firms, I find no statistically significant relation between the ratio of CEO-to-mean employee compensation and performance. I next create empirical models that allow me to separate the components of CEO and employee compensation explained by economic factors from those that are not and use these models to estimate explained and unexplained pay disparity. After validating my estimate of unexplained pay disparity as a proxy for pay fairness, I find robust evidence of a negative (positive) relation between unexplained (explained) pay disparity and future firm performance. Additional tests show that the negative relation between unexplained disparity and firm performance is driven by firms where both the CEO is overpaid and employees are underpaid and is more pronounced for firms with weak corporate governance and high employee turnover.

  1. JOE & THE JUICE Crosses the Atlantic (with video links)

    Ethan Rouen and Suraj Srinivasan

    As JOE & THE JUICE began its rapid U.S. expansion in 2017, its founder and CEO, Kaspar Basse, fretted about how he could keep his employees feeling like they were doing meaningful work. Founded in 2001, JOE & THE JUICE had always focused on making healthy juices, banning prepackaged or processed foods, and providing meaningful work for front-line food services employees. To instill employees with a sense of ownership, JOE & THE JUICE had developed a transparent promotion and compensation scheme, a rigid training program, and an explicit promise to promote only from within (the CFO was 31-years-old and had spent a decade working at the company). On the other hand, employees were encouraged to make the juice bars their homes. There were no required uniforms or scripts on how to interact with customers. This strategy had led to great success in Europe. In a decade, JOE & THE JUICE had spread across the continent and was immensely profitable. But as it moved into the United States and prepared for a potential IPO, the company began struggling to retain talent and worried about how it could successfully import its internal culture while maintaining its rapid growth.
