Describe a specific event that would make each of the following happen to a production possibilities graph.

(a) a point moves down to the
(b) the frontier shifts to the right:

(a) A point moving down on a production possibilities graph represents a decrease in the production capacity for one of the goods or services being considered. One specific event that could cause this is a natural disaster, such as a hurricane or earthquake, that damages the infrastructure or resources needed to produce the goods or services. For example, if a hurricane destroys farms, this would reduce the availability of agricultural products, causing a decrease in the production capacity for those goods.

(b) The frontier shifting to the right on a production possibilities graph represents an increase in the overall production capacity for both goods or services being considered. One specific event that could cause this is a technological advancement that improves efficiency or productivity. For instance, if a new farming technology is developed that allows for higher crop yields, this would increase the production capacity for agricultural products and shift the frontier to the right.

(a) A point moving down on a production possibilities graph represents a decrease in the production of one good or service while keeping the production of the other good or service constant. This could happen due to a decrease in resources, technological advancements in the other good/service, or a shift in consumer preferences.

For example, let's consider the production possibilities graph of a country that produces automobiles and bicycles. If there is a decrease in the availability of skilled labor for automobile production, the production of automobiles may decline. As a result, the point on the graph representing the production of automobiles would move down, indicating a decrease in automobile production. Meanwhile, the production of bicycles remains the same.

(b) The frontier shifting to the right on a production possibilities graph represents an increase in the overall production capabilities of an economy. This can occur through various factors such as an increase in resources, advancements in technology, improvements in infrastructure, or an increase in the workforce.

For example, let's consider a production possibilities graph of a country that produces agricultural goods and manufactured goods. If the country invests in new farming technologies and techniques, resulting in increased yield and efficiency in agricultural production, the country's production possibilities frontier would shift to the right. This means that the country can now produce more agricultural goods and have resources available to allocate towards the production of more manufactured goods without sacrificing the quantity of agricultural goods produced.

a) ?? Is something missing??

b) new technology would shift the curve to the right.
