In this talk I begin with a brief review of the status of approaches to
understanding the origin of the baryon asymmetry of the universe (BAU). I then
describe a recent model unifying three seemingly-distict problems facing
particle cosmology: the origin of inflation, the generation of the BAU and the
nature of dark energy.Comment: 16 pages, RevTeX, Plenary talk presented at PASCOS-03, Mumbai, India;
