Globalization

• Take advantage of favorable costs• Gain access to foreign markets• Reduced trade barriers• Changing markets


Hourly Wage Rates


Growth in Volume of World Trade


Impact of Trade Agreements


Risks In Globalization

• Weak infrastructure• Distinct languages, customs, trade barriers• Inefficient distribution channels• Instability of governments• Poor economic conditions


Competitiveness

The degree to which a nation, can, under demanding and rapidly changing market conditions, produce goods and services that meet the test of international markets while simultaneously maintaining or expanding the

real incomes of its citizens.


Measures Of Competitiveness

• Gross domestic product (GDP)

• Import/export ratio

• Productivity = output / input


Productivity Increases When Firms

• Become more efficient• Downsize• Expand• Retrench • Achieve breakthroughs


Productivity In The ‘90s


Changes In Input and Output

. .


Competitive Industries

• Relatively equal in size and resources

• Standardized products and services

• Slow or exponential growth


Measuring Competitiveness

• Number of major players

• Average market share

• Average profit margin


Barriers To Entry

• Economies of scale• Capital investment• Access to supply and distribution channels• Learning curves
