Final answer:
The risk to Walmart's effort in opening smaller Neighborhood Market stores to compete with Dollar General is the negative impact on the local economy and small businesses.
Step-by-step explanation:
One risk to Walmart's effort in opening smaller Neighborhood Market stores to compete with stores like Dollar General is the negative impact on the local economy and small businesses. Walmart's strategy of offering lower prices and a wider variety of products can lead to the closure of small businesses that can't compete with the scale and pricing power of Walmart. This can result in job losses, decreased local spending, and a decline in the economic vitality of the community.
