Final answer:
Buyers and marketers participate together in the 'Value Chain', where each step adds to the product's value. Technology and globalization have expanded market reach and competition through online platforms connecting global buyers and suppliers.
Step-by-step explanation:
The student's question pertains to a concept within the realm of business and economics, specifically related to how buyers and marketers can participate together in a particular aspect of the market. The phrase to complete the sentence is 'Value Chain'. The value chain involves all the activities and processes that add value to the product or service at every step, from inception to delivery. Both buyers and marketers play significant roles within this chain, as their interactions can influence the efficiency and optimization of the processes involved.
Marketers aim to understand and meet the needs of the consumer, effectively communicating the value of the product or service, while buyers are those who assess and decide on purchases, thus directly affecting demand. The interdependence between buyers and marketers within the value chain has been further intensified by major shifts due to technology and globalization, which have expanded market opportunities and competition through the rise of 'business-to-business' websites that connect buyers and suppliers globally.
