In the short run, the book will be a vital reference in any advanced course in macroeconomic theory. Finally, we will go over a recursive method for repeated games that has proven useful in contract theory and macroeconomics. Economic dynamic optimization problems frequently lead to a system of diﬀerential equations poten-tially augmented by algebraic equations: x˙ = f(t,x,y) (12) 0 = g(t,x,y) (13) with xǫRn d, yǫRn a, f: (R×Rn d ×Rn) → Rn d and g: (R×Rn d ×Rn a) → Rn.
