Negotiation with outside companies)  Firms seek to economize on cost of participating in market (transaction costs)  IT lowers market transaction costs for firm, making it worthwhile for firms to transact with other firms rather than grow the number of employees 2) Agency Theory:  Firm is connection of contracts among self-interested parties (employees) requiring supervision  Firms experience agency costs (the cost of managing and supervising) which rise as firm grows  IT can reduce agency costs, making it possible for firms to grow without adding to the costs of supervising, and without adding employees Organizational and Behavioral Impacts: 1) IT Flattens Organizations:  Reduces number of levels in an organization by providing managers with information to supervise large number of workers  As a result lower level employees get more decis
