摘要：
Recent work drawing on data for large and small firms has shown a Pareto distribution of firm size. We begin by showing that the firm age distribution is well approximated by an exponential distribution. We then mix a Gibrat-type growth process among incumbents with an exponential distribution of firm's age, to obtain the empirically-observed Pareto distribution.
