Eco514 Game Theory Lecture 10: Extensive Games with (Almost)Perfect Information Marciano Siniscalchi October 19, 1999 Introduction Beginning with this lecture, we focus our attention on dynamic games. The majority of games of economic interest feature some dynamic component, and most often payoff uncertainty as well. The analysis of extensive games is challenging in several ways. At the most basic level describing the possible sequences of events (choices)which define a particular game form is not problematic per se; yet, different formal definitions have been proposed, each with its pros and cons

Synchronous sequential circuit memory, usually consisting of flip-flops, update circuit states information All flip-flops share a common clock pulse input The clock input is not a binary value representing the time of day but rather a\synchronous\train of pulses. Synchronous memory changes its data only at certain time intervals The flip-flops can change state only on a clock pulse edge
