Johnny Ace's crooning style and stirring ballads made him the first postwar African American artist to cross over to a white audience. After a string of R&B hits, Ace released the million-selling "Pledging My Love," a song headed to the top of the charts when the singer accidentally shot himself in his dressing room between sets at a show. 

James M. Salem captures the enigmatic, captivating, and influential R&B legend. Venturing from raucous Beale Street to Houston's vibrant Fourth Ward, Salem places Johnny Ace within a multifaceted world of postwar rhythm and blues that included B. B. King, Johnny Otis, Big Mama Thornton, and Gatemouth Brown. Salem also examines how entrepreneur Don D. Robey and his wife Evelyn Johnson promoted Ace to the top of the charts. Yet fame, as always, had a price. Ace's tours on the Chitlin' Circuit meant endless one-night stands and a grueling schedule that kept him on the road 340 days per year. 

Comprehensive and filled with anecdotes, The Late Great Johnny Ace and the Transition from R&B to Rock 'n' Roll tells the story of the star who fused black and white styles and changed American popular music forever.

Zvi Griliches was a modern master of empirical economics. In this short book, he recounts what he and others have learned about the sources of economic growth. This book conveys the way he tackled research problems. For Griliches, economic theorizing without measurement is merely the fashioning of parables, but measurement without theory is blind. Judgment enables one to strike the right balance.

The book begins with economists' first attempts to measure productivity growth systematically in the 1930s. In the mid-1950s these efforts culminated in a startling puzzle. The growth of measured inputs like labor and capital explained only a fraction of the growth of national output. Economists called this phenomenon "efficiency" or "technical change" or "the residual." However, Griliches observes that the most accurate name was a "measure of our ignorance." What explained the rest of economic growth quickly became one of the most important questions in economics.

Over the next thirty years, Griliches and his colleagues and students looked for various components of the residual in education (the formation of human capital), investment (the formation of physical capital), and research and development. In 1973, after the oil price shocks, productivity growth slowed and the residual almost disappeared. Since the shocks were a short-term phenomenon, they could not account for the slowdown. A main focus of this book is therefore the puzzle of the productivity slowdown and how to date it and how to explain it.
