This eBook presents recent theoretical and empirical research on firms and their strategies employed in specific scenarios and industries. Readers will find, in this volume, analyses of oligopolistic industries done by using various economic models. These models attempt to explain changes to the competitive environment owing to strategic firm behavior, that is, on the assumption that firms are able to compete effectively and advantageously against rivals through applying strategic initiatives. This eBook investigates the behavior of profit-maximizing firms as well as labor-managed, state-owned and joint-stock firms. Fifteen chapters present theoretical or empirical findings, and develop economic analyses of firm behavior.
