Using economic models and empirical analysis, this volume examines a wide range of agricultural and biofuel policy issues and their effects on American agricultural and related agrarian insurance markets. Beginning with a look at the distribution of funds by insurance programs-created to support farmers but often benefiting crop processors instead-the book then examines the demand for biofuel and the effects of biofuel policies on agricultural price uncertainty. Also discussed are genetically engineered crops, which are assuming an increasingly important role in arbitrating ten.

Despite its presumed role as an engine of economic growth, we know surprisingly little about the drivers of scientific creativity. We exploit key differences across funding streams within the academic life sciences to estimate the impact of incentives on the rate and direction of scientific exploration. Specifically, we study the careers of investigators of the Howard Hughes Medical Institute (HHMI), which tolerates early failure, rewards long‐term success, and gives its appointees great freedom to experiment, and grantees from the National Institutes of Health (NIH), who are subject to short review cycles, predefined deliverables, and renewal policies unforgiving of failure. Using a combination of propensity‐score weighting and difference‐in‐differences estimation strategies, we find that HHMI investigators produce high‐impact articles at a much higher rate than a control group of similarly accomplished NIH‐funded scientists. Moreover, the direction of their research changes in ways that suggest the program induces them to explore novel lines of inquiry.

Also discussed are genetically engineered crops, which are assuming an increasingly important role in arbitrating tensions between energy production, environmental protection, and the global food supply. Other contributions discuss the major effects of genetic engineering on worldwide food markets. By addressing some of the most challenging topics at the intersection of agriculture and biotechnology, this volume informs crucial debates
