Business today is by all measures “global”. No business or industry of any size is immune from the global environment. Even small businesses that purchase and sell only in their home countries are subject to competition from products coming into their home countries from overseas or from global issues when their suppliers or consumers become global. therefore, even employees of such companies are affected by the global environment. Understanding the global economy, therefore, is necessary for all engaged in business and careers regardless of the size or type of business or career endeavor .
