How does globalization expand businesses?
Globalization expands businesses by opening up geographical and economical borders and barriers. You're able to purchase materials and labor from around the world based on the lowest cost possible. By going global through licencing and franchising agreements with your product, you aren't just selling to the local economy, you're selling to the most customers possible for the largest profit possible.
You may have trouble affording materials from your suppliers here in the US. due to rising costs; with a little research you find that you can get the materials less expensive, say, from Romania or France; with trade agreements, licencing and franchising you're able to get your materials from their country as well as sell to their market which opens up two more markets to you rather than just your geographical location or just here in the US.
