As a result of money in an economy,

a. transaction costs are higher than would be the case in a barter economy.
b. stealing exists and people have to find ways to prevent theft.
c. real gross domestic product (gdp) and economic growth are greater than they would be in a barter economy.
d. people are greedier than in a barter economy.

As a result of money in an economy, the real Gross Domestic Product(GDP) and economic growth are greater than they would be in a barter economy.

Option C

Explanation:

The economic growth and real GDP are higher in the money economy than in the barter economy because money processed exchanges cheaper, therefore, people are more comfortable to manufacture, cultivate or produce their specialized material and buy other necessary commodities by earning money after selling off their specific goods or services.

Such a phenomenon hiked the production and consumption level in-country or world; it also empowered goods and services which in turn hiked the value of it in both the national and international markets.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.

hello,

answer: a federal government has final authority on interstate/inter provincial  and international affairs, a confederation is one where the central/national government or authority is governing body what does not have final say over the same matters. hopefully this and i will try again if you don't like this answer : )
