During the Maurya Empire (c. 321-185), there were a number of important changes and developments to the Indian Economy. It was the first time in India that was unified under one ruler.With an empire in place, the trade routes throuout India became more secure thereby reducing the risk associated with the transportation of goods.The empire spent resources building roads and maintaining them throughout India. The improved infrastructure combined with increased security, greater uniformity in measurement, and increasing usage of coins as currency enhanced trade. During this time, the Arhasastra was written by the Chanakya, an adviser to Chandragupta Maurya.The economic situation in the Maurya Empireis comparable to the Roman Empire several centuries later, which both had extensive trade connections and both had organizations similar to corporation.
