We link farmland values to climatic, soil, and socioeconomic variables for counties east of the 100th meridian, the historic boundary of agriculture not primarily dependent on irrigation. Degree days, a non-linear transformation of the climatic variables suggested by agronomic experiments as...

We define the irreversibility effect and demonstrate its importance in problems involving investment decisions under uncertainty. We establish several analytical and numerical results that suggest both that the effect holds more widely than generally recognized, and that an existing result...

Among others who point to environmental variability and managerial uncertainty as causes of fishery collapse, Roughgarden and Smith (Proc. Natl. Acad. Sci. 93 (1996) 5078) argue that three sources of uncertainty are important for fisheries management: variability in fish dynamics, inaccurate...

The striped bass population in the San Francisco Bay/Delta estuary has been declining over the past two decades. Though the decline has been studied intensively, the causes are not completely understood. In this report we provide a review of theories about the decline, empirical evidence, and...
