What factors contribute to the comparative advantages of countries?

Answers

Answer:

International trade is the exchange of capital, goods, and services across international borders or territories.

Each nation should produce goods for which its domestic opportunity costs are lower than the domestic opportunity costs of other nations and exchange those goods for products that have higher domestic opportunity costs compared to other nations.

Benefits of trade include lower prices and better products for consumers, improved political ties among nations, and efficiency gains for domestic producers.

International trade is the exchange of capital, goods, and services across international borders or territories. Trading-partners reap mutual gains when each nation specializes in goods for which it holds a comparative advantage and then engages in trade for other products. In other words, each nation should produce goods for which its domestic opportunity costs are lower than the domestic opportunity costs of other nations and exchange those goods for products that have higher domestic opportunity costs compared to other nations.

Explanation:

In economics, the production possibility frontier (PPF) is a graph that shows the combinations of two commodities that could be produced using the same total amount of the factors of production. It shows the maximum possible production level of one commodity for any production level of another, given the existing levels of the factors of production and the state of technology.

PPFs are normally drawn as extending outward around the origin, but can also be represented as a straight line. An economy that is operating on the PPF is productively efficient, meaning that it would be impossible to produce more of one good without decreasing the production of the other good. For example, if an economy that produces only guns and butter is operating on the PPF, the production of guns would need to be sacrificed in order to produce more butter. If production is efficient, the economy can choose between combinations (i.e., points) on the PPF: B if guns are of interest, C if more butter is needed, or D if an equal mix of butter and guns is required.

Chris wants to accumulate $112,000 in 4 years. He plans on making equal semiannual deposits into an investment account that earns 10% semiannually in order to reach his goal. How much must Chris invest every six months

Answers

Answer:

$11,728.85

Explanation:

the future value of the annuity = $112,000

number of periods = 8 semiannual payments

interest rate = 10% compounded semiannually = 5%

future value = payment x FV annuity factor

FV annuity factor 5%, 8 periods = 9.5491

payment = $112,000 / 9.5491 = $11,728.85

a. 5.2% to 22.0%.
b. 3.2% to 30.4%.
c. 3.2% to 30.4%.
d. 5.2% to 22.0%.
e. 13.6% to 38.8%.

Answers

Answer:

options B and C are identical, and they are both right.

b. 3.2% to 30.4%. c. 3.2% to 30.4%.

you have a 95% chance that you will not lose more than 3.2% nor earn more than 30.4% if you invest in this security.

Explanation:

a 95% confidence level represents approximately 2 standard deviations, so the stock could lose up to 13.6% - (2 x 8.4%) = -3.2% in the worse case scenario. You should also be able to earn 13.6% + (2 x 8.4%) = 30.4% in the best case scenario.

Paolo owns a pizza shop. The price of pizza recently increased from $3 to $5 a slice. Paolo responded by increasing the quantity of slices he supplied from 100 to 150 slices per day. By the midpoint method, Paolo's price elasticity of supply is:_______.

Answers

Answer:

Paolo's price elasticity of supply is 0.80.

Explanation:

From the question, we have:

New quantity supplied = 150

Old quantity supplied = 100

New price = $5

Old price = $3

Generally, the formula for calculating the price elasticity of supply is as follows:

Price elasticity of supply = Percentage change in quantity supplied / Percentage change in price ................ (1)

Where, based on the midpoint formula, we have:

Percentage change in quantity supplied = {(New quantity supplied - Old

quantity supplied) / [(New quantity supplied + Old quantity supplied) /

2]} * 100 = {(150 - 100) / [(150 + 100) / 2]} * 100 = 40%

Percentage change in price = {(New price - Old price) / [(New price + Old

price) / 2]} * 100 = {(5 - 3) / [(5 + 3) / 2]} * 100 = 50%

Substituting the values into equation (1), we have:

Price elasticity of supply = 40% / 50% = 0.80

Therefore, Paolo's price elasticity of supply is 0.80.

The compound interest is usually greater than simple interest because it pays interest on the principal and the interest earned in each period.

What is compound interest?

Compound interest is the interest payment that increases on the first sum of money and any earned interest over time. It is usually calculated on the accumulated amount of money.

Compound interest is greater than simple interest because the simple interest is always calculated on the principal amount, which means if the principal is 100 and the rate of interest is 10%, then the simple interest for every year is $10.

A survey reveals that, on a small island, 175 people have jobs, 25 people are not working but are looking for jobs, and 90 people are neither working nor looking for work. The unemployment rate on the island is:____.

Answers

Answer:

The answer is = 12.5%

Explanation:

The 175 people that have jobs are in unemployment (employed).

The 25 people that are not working but are looking for jobs are called unemployed.

The 90 people are neither working nor looking for work for work are not counted in the employment.

Therefore, the labor force is employed people + unemployed people.

Labor force is 175 + 25= 200 people.

So, unemployment rate is:

(unemployed people ÷ labor force) x 100

(25÷200) x 100%

=12.5%

Investors tend to focus on the bottom line when conducting financial analyses. Thus far, you have calculated earning; per share (EPS) as the net income available to common shareholders divided by the number of common shares outstanding. However, when firms use a lot of hybrid securities, their earnings can be distorted. As a result, a few different methods exist for reporting EPS. Primary EPS is the EPS found after adjusting for the number of shares that are likely to be issued from convertibles and warrants.
Read the following statement, which describes one of these reporting methods:
Earnings per share are found based on the assumption that all convertibles and warrants are exercised rather than trying to estimate how many of them are likely to be exercised. Identify which of the reporting methods this statement describes:
A. Diluted EPS.
B. Basic EPS.
C. Primary EPS.

Answers

Answer:

The reporting method described by the statement is:

A. Diluted EPS.

Explanation:

Diluted EPS gauges the quality of a company's earnings per share (EPS) as if all convertible securities were exercised.  Convertible securities include the company's outstanding convertible preferred shares, convertible debentures, stock options, and warrants.  The diluted EPS is different from the basic EPS (otherwise called the Primary EPS).  The basic EPS measures the company's earnings per common share without considering any outstanding convertible securities.

Vaughan Interiors needs help determining the Stockholders' Equity Account. Current account balances are: Cash $25,050, Accounts Receivable $12,400, Equipment $40,000, Accumulated Depreciation $22,750, Accounts Payable $15,750, Salaries Payable $12,150. What is the Stockholders' Equity Account Balance

Answers

Answer:

$1,750

Explanation:

Stockholder's equity would be calculated as;

= Current assets balance + Fixed asset balance - Current liability balance

Current assets balance = Cash $25,050 + Accounts receivable $12,400

Fixed assets = Equipment $40,000 - Accumulated depreciation $22,750 = $17,250

Current liability = Accounts payable $15,750 + Salaries payable $12,150 = $27,900

Therefore,

Stockholder equity account balance

= $12,400 + $17,250 - $27,900
