A persistence rise in the prices of inputs will lead to

Detalles de la respuesta

A persistence rise in the prices of inputs, such as raw materials or labor, can lead to **cost push inflation**. Cost push inflation occurs when the increased costs of production for firms are passed on to consumers in the form of higher prices for goods and services. This can happen when the prices of inputs used in production rise over a sustained period. When input costs increase, businesses often have two options: absorb the increased costs and accept lower profit margins, or pass on the higher costs to consumers by raising prices. If firms choose to raise prices, it can lead to a general increase in the overall price level in the economy. Here's a simple example to help illustrate this concept: Let's say there is a town where the main industry is manufacturing shoes. The cost of leather, which is a key input in shoe production, starts to rise due to factors like high demand or scarcity. In response, shoe manufacturers have to pay more for leather, and this increases their production costs. To maintain their profit margins, the manufacturers decide to increase the prices of shoes they sell to retailers. Now, if the retailers decide to pass on the higher costs to the consumers, the prices of shoes will increase. This can create a ripple effect throughout the economy because consumers will have to spend more money on shoes, reducing their purchasing power for other goods and services. As a result, the overall price level in the economy increases, and this is what we call cost push inflation. It is important to note that cost push inflation is different from demand pull inflation. Demand pull inflation occurs when there is an increase in aggregate demand, leading to an excess of demand over supply. In contrast, cost push inflation is driven by increased production costs. Hyperinflation, on the other hand, is an extreme form of inflation characterized by an uncontrollable increase in prices. It is typically caused by factors like rapid money supply growth or loss of confidence in the currency. Stagflation refers to a situation where there is a combination of high inflation and high unemployment, typically accompanied by low economic growth. This can occur when an economy experiences a supply-side shock, such as a significant increase in the prices of key inputs. In summary, a persistence rise in the prices of inputs can lead to cost push inflation, as firms pass on the increased costs to consumers by raising prices.

Which of the following is the resultant effect of a fall in the profit margin of producers in an economy?

Detalles de la respuesta

A fall in the profit margin of producers in an economy will likely result in an increase in unemployment.
When the profit margin of producers decreases, it means that they are earning less profit from their business activities. As a result, they may struggle to cover their costs, sustain their operations, or expand their businesses. To manage their financial situation, producers may need to cut costs, reduce production, or even close down their business altogether.
Reduced production and business closures lead to a decrease in job opportunities and an increase in unemployment. When businesses are not making enough profit, they may need to lay off workers or reduce their workforce in order to cut costs. This means that fewer people will have jobs, resulting in higher unemployment rates.
Additionally, a fall in profit margins can also deter new businesses from entering the market or existing businesses from expanding. This further limits job creation and can exacerbate the unemployment problem.
In summary, a fall in the profit margin of producers in an economy leads to reduced production, business closures, job cuts, and a decrease in job opportunities. Therefore, the most likely resultant effect of such a decline in profit margin is an increase in unemployment.

To find the value of L when the supply (s) is equal to 20, we can use the given supply curve equation: S = 4L + 8.
The supply curve equation represents how much labor (L) will be supplied at a given wage rate (s). In this case, the equation tells us that the supply of labor is equal to 4 times the quantity of labor (L) plus 8.
To find L when s = 20, let's substitute s = 20 into the equation:
20 = 4L + 8
Next, let's isolate L by subtracting 8 from both sides of the equation:
20 - 8 = 4L
Simplifying further:
12 = 4L
Now, we need to solve for L. We can do this by dividing both sides of the equation by 4:
12/4 = 4L/4
Simplifying again:
3 = L
Therefore, when the supply (s) is equal to 20, the value of L is 3.
So the correct answer is 3.

Which of the following will cause an increase in cost of production?

Detalles de la respuesta

Cost push inflation occurs when overall prices increase(inflation) due to increases in the cost of wages and raw materials. It can also occur when higher costs of production decrease the aggregate supply in the economy.

The demand for a good is price inelastic if the price elasticity is less than one. Price elasticity measures how responsive the quantity demanded of a good is to a change in its price. If the price elasticity is less than one, it means that the quantity demanded is not very responsive to changes in price. In other words, a change in price will have a relatively small impact on the quantity demanded. Even if the price increases or decreases, people will still buy a similar amount of the good. This can happen when the good is a necessity or when there are limited substitutes available. For example, if the price of water increases, people will still need to buy a similar amount because water is essential for survival. Similarly, if the price of a specific medication increases, people with no alternative options will still purchase it regardless of the price. Therefore, when the price elasticity is less than one, we say that the demand for the good is price inelastic.

Economists refer to private goods as

Detalles de la respuesta

Private goods are referred to as rivalrous and excludable by economists. Let me explain what this means in a simple and comprehensive way.
When a good is rivalrous, it means that one person's use or consumption of the good diminishes its availability for others. For example, if you eat an orange, there is now one less orange for someone else to consume. The consumption of the orange by one person reduces the availability of the orange for others.
On the other hand, when a good is excludable, it means that it is possible to prevent someone from using or consuming that good if they do not pay for it. For instance, if you go to a movie theater and buy a ticket, you are allowed entry to watch the movie. However, if you do not buy a ticket, you will be excluded from watching the movie.
Private goods possess both of these characteristics. They are rivalrous because one person's use or consumption of the good reduces its availability for others. For example, if you buy a car, only you can use it at any given time, and someone else cannot simultaneously use it. Private goods are also excludable because it is possible to prevent others from using or consuming the good if they do not pay for it. For instance, if you purchase a book, you have exclusive access to read it unless you choose to share it with someone.
In summary, private goods are referred to as rivalrous and excludable because their consumption diminishes their availability for others, and it is possible to exclude others from using or consuming them if they do not pay for them.

The short run can be defined as the period of time during which at least one of the firm's inputs is fixed. In other words, it is a time frame in which the firm cannot easily or quickly adjust all of its inputs. This means that some resources, such as the size of a factory or the number of employees, cannot be changed in the short run.
During the short run, firms can only adjust their production levels by varying the amount of variable inputs, such as raw materials or utilities. The fixed input, which remains constant in this period, imposes limitations on the firm's ability to increase or decrease its output. This constraint on adjusting all inputs is what distinguishes the short run from the long run, where all inputs can be varied.
It is important to note that the length of the short run can vary depending on the industry and the specific circumstances of the firm. For some businesses, the short run may be a few months, while for others it could be several years. However, what remains consistent is that during the short run, the firm is restricted in its ability to modify certain inputs, which can impact its production and overall performance.

Institutions serving as links between surplus and deficit units can be identified as

Detalles de la respuesta

Financial intermediaries serve as links between surplus and deficit units in an economy. These intermediaries include banks, credit unions, and other financial institutions. When there is surplus money in the economy, individuals and businesses deposit the excess funds with financial intermediaries. These intermediaries then pool these funds together and make them available to deficit units, such as individuals or businesses in need of loans or financing. Financial intermediaries play a crucial role in the economy by efficiently allocating funds from surplus units to deficit units. They match the needs of borrowers with the resources of savers, helping to facilitate economic growth and development. Tax officers and pension offices, on the other hand, do not serve as direct links between surplus and deficit units. Tax officers collect taxes for the government, while pension offices manage pension funds for retired individuals. Although these entities may indirectly impact the allocation of funds in the economy, their primary roles are different from that of financial intermediaries. Acceptance houses are also not direct links between surplus and deficit units. Acceptance houses provide short-term financing through the purchase of bills of exchange. While they play a role in facilitating trade between businesses, their function is more specific and limited compared to the broader role of financial intermediaries. In summary, financial intermediaries such as banks and credit unions serve as the primary links between surplus and deficit units in an economy. They gather surplus funds from savers and make them available to borrowers, thereby promoting the efficient allocation of resources.

.............is presently used in Nigeria to measure inflation

Detalles de la respuesta

The measure that is presently used in Nigeria to measure inflation is the Consumer Price Index (CPI). The CPI is a commonly used indicator worldwide to track changes in the cost of living over time.
The Consumer Price Index (CPI) measures the average price changes of a basket of goods and services typically purchased by households in a specific country or region. It reflects the price movements of essential items such as food, housing, transportation, healthcare, education, and many other goods and services that people consume regularly.
The CPI is calculated by collecting price data for various items in the basket and assigning them weights based on their relative importance in household spending. The prices are then compared to a base period, which is usually a specific year. The percentage change in the CPI from the base period indicates the rate of inflation or deflation.
In Nigeria, the CPI is used to monitor and analyze changes in the cost of goods and services, allowing policymakers and economists to assess the impact on consumers' purchasing power and make informed decisions. It helps in determining the effectiveness of government policies, evaluating the performance of the economy, and adjusting wages and prices.
By tracking the CPI, the government can identify if there is an increase in the general level of prices, indicating inflation, or a decrease, indicating deflation. This information helps in formulating monetary and fiscal policies to control inflation rates and maintain price stability.
Overall, the Consumer Price Index (CPI) is the measure currently used in Nigeria to gauge inflation and is crucial in understanding how the cost of living changes over time, impacting the economy and the daily lives of individuals and businesses.

In a two by two model of international trade, it is assumed that

Detalles de la respuesta

In a two by two model of international trade, it is assumed that **both countries could gain from trade at the same time, but the volume of the gains depends on terms of trade**. This means that both countries can benefit from engaging in trade with each other. Trade allows both countries to specialize in producing and exporting the goods in which they have a comparative advantage, while importing goods that they are less efficient at producing. This leads to increased efficiency and overall economic gains for both countries. However, the volume of the gains from trade depends on the terms of trade between the two countries. The terms of trade refer to the ratio at which the countries exchange their goods. If one country has a higher bargaining power or can produce goods at a lower cost, they may negotiate more favorable terms of trade, leading to a larger volume of gains for that country. On the other hand, if the terms of trade are less favorable, the volume of gains for both countries may be smaller. In summary, while both countries can benefit from trade, the extent of the gains will vary depending on the terms of trade negotiated between them.

Given the table demonstrating the law of diminishing marginal utility below, what is the value of X?

Detalles de la respuesta

The Marginal Utility is the additional satisfaction a consumer gains from consuming one more unit of a good or service. It can be calculated by subtracting the total utility of the previous consumption from the total utility of the current consumption. In this case, the total utility of consuming 2 oranges is 16 and the total utility of consuming 1 orange is 9. Therefore, the marginal utility (X) of the second orange is 16 - 9 = 7.

The decision to consume more of one product under normal circumstances will apply

Detalles de la respuesta

The decision to consume more of one product under normal circumstances will **result in less consumption of another product**. When we have a limited amount of resources, we can only allocate them in certain ways. This is true for both individuals and businesses. If we choose to consume more of one product, it means we are using some of our resources to produce more of that product. As a result, we have less resources available to produce or consume other products. Let's take an example to understand this concept better. Suppose you have $10 to spend on food, and you can either choose to buy more fruits or more vegetables. If you decide to buy more fruits, it means you are allocating more of your budget towards fruits. As a result, you will have less money left to buy vegetables. On the other hand, if you decide to buy more vegetables, it means you are allocating more of your budget towards vegetables, and you will have less money left to buy fruits. Similarly, in a market economy, if consumers decide to buy more of one product (like smartphones), the demand for that product increases. This leads to an increase in production and consumption of smartphones. However, the resources used to produce smartphones are limited. Therefore, the production of other products (like laptops or tablets) may decrease because fewer resources are available to produce them. In conclusion, when the decision is made to consume more of one product, it generally means that less of another product will be consumed. This is because resources are limited and need to be allocated among different options.

Detalles de la respuesta

The diagram above represents the production possibility curve.
The production possibility curve shows the different combinations of goods and services that can be produced given the available resources and technology.
On the curve, each point represents a specific combination of goods and services that can be produced. Points on the curve are considered efficient because all available resources are fully utilized. Points inside the curve represent inefficient production because resources are not fully utilized. Points outside the curve represent combinations that are currently unattainable given the available resources and technology.
In summary, the production possibility curve helps us understand the trade-offs and limitations in production based on available resources and technology. It is a visual representation of the production possibilities in an economy.

An increase in nominal income without increase in price will result to

Detalles de la respuesta

An increase in nominal income without an increase in prices will result in an **increased real income**. Nominal income refers to the amount of money a person earns or receives in a given period, without taking into account changes in prices. On the other hand, real income takes into consideration the effects of inflation by adjusting for changes in prices. When nominal income increases but prices remain constant, it means that the purchasing power of an individual's income has increased. In other words, they can afford to buy more goods and services with the same amount of money. This increase in purchasing power leads to an increase in real income. For example, let's say a person's nominal income is $1,000 per month, and the prices of goods and services they consume also remain constant. If their nominal income increases to $1,200 per month, without any increase in prices, they now have an additional $200 to spend on other things. This additional purchasing power translates to an increase in their real income. It is important to note that an increase in nominal income without an increase in prices does not necessarily lead to an **increased GDP** or a **decreased GNP**. GDP (Gross Domestic Product) measures the total value of goods and services produced within a country's borders, while GNP (Gross National Product) measures the total value of goods and services produced by a country's residents, including those produced abroad. The increase in real income of individuals does not automatically impact the overall production levels captured by GDP or GNP.

Government uses all of the following ways to redistribute income, except

Detalles de la respuesta

The government uses various methods to redistribute income in society. Three of these ways are market intervention, transfer earnings, and taxation. Market intervention involves the government stepping in and regulating certain aspects of the economy to ensure fairness and reduce income inequality. For example, the government may set a minimum wage so that workers are guaranteed a certain level of income. Transfer earnings refer to government programs that provide financial assistance to individuals or families who are in need. These programs include welfare, unemployment benefits, and social security. The goal is to provide support to those who may have lower incomes or are facing financial difficulties. Taxation is another method used by the government to redistribute income. Through taxes, the government collects money from individuals and businesses based on their income or profits. This revenue is then used to fund public services such as healthcare, education, infrastructure, and social programs. However, the answer to the question is that the government does not use limited liability as a way to redistribute income. Limited liability is a legal concept that protects individuals from being personally liable for the debts and liabilities of a company. It is not directly related to income redistribution. In summary, the government redistributes income through market intervention, transfer earnings, and taxation. These methods aim to promote fairness and provide support to those in need. However, limited liability is not a method used for income redistribution.

Indicator of underdevelopment is

Detalles de la respuesta

An indicator of underdevelopment is low per capita income. Per capita income refers to the average income earned by individuals in a country. In underdeveloped countries, the per capita income is generally low, meaning that people have lower incomes on average compared to developed countries.
Low per capita income is a significant indicator of underdevelopment because it directly affects the standard of living of people within a country. With low income, individuals have limited purchasing power, making it difficult for them to afford basic necessities such as food, clothing, and shelter. This can lead to overall poor living conditions and a lack of access to essential services like healthcare and education.
Additionally, low per capita income also implies limited economic opportunities and a weak economy. It suggests that the country's productivity and industrial development are low, leading to low wages and limited job opportunities. This can result in high levels of poverty and unemployment, further hindering the country's development.
In summary, low per capita income is a crucial indicator of underdevelopment because it reflects the overall economic situation of a country and directly impacts the living conditions and opportunities available to its citizens.

Suppose the public expenditure as a percentage of GDP of four countries is shown in the table below

Which type of economy exists in these countries?

Detalles de la respuesta

The type of economy that exists in these countries is Mixed economy.

A mixed economy is an economic system that combines elements of both market and planned economies. It includes both private and public sectors, and the government plays a significant role in regulating and defining the structure of the economy.

In the given scenario, the fact that the countries have different levels of public expenditure as a percentage of GDP indicates that the government plays a role in the economy and is involved in spending a portion of the national income.

While the exact percentage of public expenditure varies between the countries, the presence of any public expenditure suggests government intervention and regulation in the economy. This means that these countries have a mixed economy, where both public and private sectors coexist and contribute to economic activities.

The government's involvement can take various forms, such as funding public goods and services, implementing social programs, and regulating industries. The level of government intervention may vary, but the presence of public expenditure indicates that the government has an active role in shaping the economy.

Therefore, based on the information provided, it can be concluded that the countries mentioned in the table have a mixed economy.

The law of supply states that, other things being constant, as price increases

Detalles de la respuesta

The law of supply states that, other things being constant, as price increases, the quantity supplied also increases. Basically, when the price of a good or service goes up, suppliers have an incentive to produce and sell more of that item. This is because they can earn more profit by selling at the higher price. So, as the price rises, suppliers are motivated to increase their production and offer more of the product to the market. On the other hand, when the price of a good or service decreases, suppliers have less motivation to produce and sell it. This is because they can earn less profit or even incur losses at the lower price. As a result, they will reduce the quantity supplied. In summary, the law of supply tells us that there is a direct relationship between price and quantity supplied. When the price increases, suppliers respond by increasing the quantity they are willing to supply to the market. Conversely, when the price decreases, the quantity supplied decreases.

40 men were employed in a farm, and they produced an average of 30 tonnes of cassava per person. Calculate the total product.

Detalles de la respuesta

To calculate the total product of cassava, we need to multiply the average production per person by the number of people.
In this scenario, we know that there were 40 men employed in the farm, and each person produced an average of 30 tonnes of cassava.
So, to find the total product, we need to multiply 40 by 30.
40 x 30 = 1200
Therefore, the total product of cassava is 1,200 tonnes.

Macroeconomics focuses on the following units in an aggregative manner

Detalles de la respuesta

Macroeconomics focuses on the units of an economy in an aggregative manner, meaning it looks at the economy as a whole rather than focusing on individual units. This helps us understand how different parts of the economy interact and influence each other.
The correct option is **household, firms, government, corporate sector, and external sector**. Macroeconomics analyzes the behavior and interactions of these units to understand the overall performance of the economy.
1. **Households**: These are the individual consumers who make up the economy. They play a vital role in determining the consumption and saving patterns that influence economic activities.
2. **Firms**: Firms are the businesses that produce goods and services in the economy. Macroeconomics looks at their investment decisions, production levels, and employment to understand the overall economic growth and productivity.
3. **Government**: The government plays a significant role in macroeconomics. It collects taxes, provides public goods and services, regulates the economy, and influences economic policies such as fiscal and monetary measures to stabilize the economy.

4. **External sector**: The external sector represents international trade and the flow of goods, services, and capital across borders. Macroeconomics considers factors like exports, imports, exchange rates, and foreign investment to understand the impact of global interactions on the economy.
By examining these units in an aggregative manner, macroeconomics helps us understand how changes in one sector affect the others and ultimately impact the overall performance of the economy.

When a kilogram of carrot is #8.00, 20 kilograms are demanded and when the price decreased to #6.000 per kilogram, 30 kilograms are demanded. The elasticity of demand equals to

Detalles de la respuesta

To calculate the elasticity of demand, we need to compare the changes in price and quantity demanded.
First, let's calculate the percentage change in price:
% change in price = ((new price - old price) / old price) x 100
% change in price = ((6 - 8) / 8) x 100
% change in price = (-2 / 8) x 100
% change in price = -25%
Next, let's calculate the percentage change in quantity demanded:
% change in quantity demanded = ((new quantity demanded - old quantity demanded) / old quantity demanded) x 100
% change in quantity demanded = ((30 - 20) / 20) x 100
% change in quantity demanded = (10 / 20) x 100
% change in quantity demanded = 50%
Now, let's calculate the elasticity of demand:
Elasticity of demand = % change in quantity demanded / % change in price
Elasticity of demand = 50% / -25%
Elasticity of demand = -2
The elasticity of demand is -2.
Explanation:
The negative sign in the elasticity of demand (-2) indicates that the demand for carrots is price elastic. This means that a decrease in price by 1% will lead to a more than proportionate increase in quantity demanded by 2%. In simpler terms, when the price of carrots decreased by 25%, the quantity demanded increased by 50%.
Therefore, the elasticity of demand is -2, which means that the demand for carrots is price elastic.

But since price elasticity is always represented with a positive number, the answer is 2
