Hy are most production possibilities frontiers (ppfs) for goods bowed outward (concave downward)?
Vika [28.1K]

When there are not enough productive resources, the production possibility frontier (PPF) slopes downward, but when resources are distributed according to their comparative advantages, it bends outward. According to the law of rising opportunity cost, this allocation will likely result in an adverse outcome.

This is further explained below.

<h3>Hy is most production possibilities frontiers (PFS) for goods bowed outward (concave downward)?</h3>

Generally,  The Productivity and Potential Frontier is sloping downward because there are not enough productive resources, but it is bowing outward because resource allocation is driven by comparative advantage.

The term "resource" refers to all of the resources that are present in our surroundings, are possible from a financial, cultural, and technical standpoint, and are available to us so that we may fulfill our requirements and gratify our desires.

In conclusion, The scarcity of productive resources is what causes the PPF to slope downward. It follows that the rule of growing opportunity cost will be valid if such an allocation is performed.

Summary of Spanish- American war

The Spanish-American war was a conflict between America and Spain in 1898 effectively due to the intervention of US in the ongoing Cuban War of Independence. United States was attacked Pacific possessions of Spain led to the involvement in the case of Philippine Revolution as well as to Philippine- American war. The public opinion of America was grown at reports of Spanish Atrocities in Cuba. United States tariff had put restrictions on sugar imports to America and severely hurt the economy of Cuba that was dependent on the producing and selling sugar.

The main issue was that Cuban independence, the ten-week war was fought in the case of both Caribbean and Pacific. United States had many business men with the investment interests in the case of Cuba that became concerned. The public of United States was stirred into anti- Spain frenzy due to the Yellow journalism of men including Hearst and Pulitzer. In 1898, America was dispatched the USS Maine on a friendly mission to Cuba. American fought the war in the case of fronts such as Cuba after the declaration. In 1898, the Treaty of Paris was signed in order to ending the Spanish- American war.

After the Spanish-American war, America was improved Cuba in the case of infrastructure and educational systems and United States had also decided to move from their places. In 1901, America was forced Cuba for inserting the Platt Amendment in the case of their constitution that have given the US military base. America was also kept the Island countries for ships in Cuba. This is the summary of Spanish-American war.

Increasing Spanish-Cuban Tensions (19th century)

Cuba had been a colony of Spain and this Spain was dependent upon sugar production. In 19th century, many people in Cuba were dissatisfied with the ruling Spanish regime. The government of Spanish was also riddled with the inefficient, corruption and unwilling for granting Cuban populations. As a result, nationalist of Cuban people wanted for ending Spanish rule for the protection of Cuban. After the war, Spanish promised reforms and but the nationalists assumed this too late. The Spanish would leave for US intervention and because of American had significant economic investment in Cuba.

In 1896, the Spanish was sent the general to Cuba in order to putting down the insurrection and the general was built the camps in order to prevent the insurrectos from leading population against Spanish rule. In Cuba, the segments of US public were outraged by the reports of atrocities. In 1895, Cuban revolt included a general opposition to a long history of Spanish control. The tariff raised prices in the sugar products that were imported from Cuba in the case of protecting US sugar growers.
