      Examining Race and Mass Incarceration in the United States

      The late 20th century saw dramatic growth in incarceration rates in the United States.

      Private and Social Returns to R&D: Drug Development and Demographics

      by Efraim Benmelech, Janice Eberly, Dimitris Papanikolaou, and Joshua Krieger

      Research and development (R&D) by pharmaceutical firms focuses disproportionately on medical conditions afflicting the elderly. The proportion of R&D spending targeting older age groups is increasing over time. Even though these investments in R&D prolong life expectancy and improve quality of life, they have little effect on measured productivity and output growth.

      by Christine L. Exley and Judd B. Kessler

      by Christine L. Exley, Nils H. Lehr, and Stephen J. Terry

      by Matt Lowe, G V Nadhanael, and Benjamin N. Roth

      by Lauren Cohen, Umit G. Gurun, and Quoc H. Nguyen

      by Eva Ascarza, Oded Netzer, and Julian Runge

      Many digital products offer “freemiums”: that is, part of the product for free, often with advertising, and an enhanced customer experience for payment. This research, in a mobile game context, shows the importance of recognizing the short- and long-term effects on customer retention when managing the tradeoffs between free and paid aspects of freemium products.
