The bank type responsible for the formulation of rules and regulations guiding the banking industry is known as?

Bayanin Amsa

The bank type responsible for the formulation of rules and regulations guiding the banking industry is the Central bank. A central bank is an independent financial institution that oversees the monetary policy and banking system of a country. Its main functions include regulating commercial banks, managing the country's money supply, and controlling inflation. The central bank is also responsible for formulating rules and regulations that guide the banking industry, as well as ensuring compliance with these rules. In many countries, the central bank is the lender of last resort, meaning that it provides emergency loans to commercial banks in times of financial crisis. Examples of central banks include the Federal Reserve in the United States, the European Central Bank in Europe, and the Bank of Japan in Japan.

Human wants are insatiable because wants are____________

Bayanin Amsa

Want may be defined as insatiable desire or need by human beings to own goods or services that give satisfaction. Human wants or needs are many, and are usually described as insatiable because the means of satisfying them are limited or scarce

In the history of economics the concept of division of labour is usually associated With______________-

Bayanin Amsa

The concept of division of labor is usually associated with Adam Smith, a Scottish economist who lived in the 18th century. Smith is known as the father of modern economics and his book "The Wealth of Nations" is considered a landmark in the history of economic thought. Division of labor is the process of breaking down the production of goods or services into smaller tasks, with each worker specializing in a particular task. Smith argued that this specialization allows workers to become more efficient and productive, as they become more skilled at their specific task over time. He famously used the example of a pin factory to illustrate the benefits of division of labor, showing how the productivity of the workers could be increased by breaking down the process of pin-making into smaller, specialized tasks. Smith believed that the division of labor not only increased productivity, but also led to economic growth and prosperity. By allowing each worker to focus on their specific task, and by encouraging trade and exchange between different workers and regions, the economy as a whole could become more efficient and produce more goods and services. This, in turn, would lead to greater wealth and prosperity for society as a whole. Overall, Smith's ideas about the division of labor had a profound impact on the development of modern economics and are still widely studied and discussed today.

The need to construct a scale of preference is necessitated by____________

Bayanin Amsa

The need to construct a scale of preference is necessitated by scarcity and the need for choice. Resources are limited, but human wants and needs are unlimited. This creates a situation of scarcity, where people must make choices about how to allocate their resources to satisfy their most pressing needs and wants. A scale of preference is a tool that helps individuals to prioritize their wants and needs, so that they can make informed choices about how to allocate their limited resources. For example, imagine you have a limited amount of money to spend on groceries for the week. You have a long list of items you want to buy, but you can't afford to buy them all. By constructing a scale of preference, you can prioritize the items on your list according to how important they are to you. You might decide that buying bread, milk, and vegetables are your top priorities, while buying luxury items like chocolates and wine are lower on your list. This allows you to make the most of your limited resources and satisfy your most pressing needs first. Therefore, the need to construct a scale of preference is necessitated by scarcity and the need for choice, as it helps individuals to allocate their limited resources in a way that best satisfies their wants and needs.

Which of the following is not a direct tax?

Bayanin Amsa

The formula (index of export prices)/(index of import prices) x 100 is used to measure the____________

Bayanin Amsa

Term of trade refer to the rate at which a country’s exports exchange for its import. It is expressed as a relation between the prices a country receives for its export and the prices it pay for import. Term of trade is usually measured by this mathematical formula:

The reward for capital is___________

Bayanin Amsa

The reward for capital refers to the return or compensation that an investor receives for providing their money as an investment in a business or project. This reward can take various forms, but some common ones are interest, rent, and dividends. Interest is a reward for lending money, and it is usually expressed as a percentage of the amount borrowed. For example, if you lend $1,000 to a company that promises to pay you 5% interest, you will receive $50 in interest payments each year. Rent is another form of reward for capital, and it is often associated with real estate. If you own a property and rent it out to tenants, you receive a regular income stream in the form of rent payments. This income can be a reward for the capital you have invested in the property. Risk is also a consideration when it comes to the reward for capital. Investments with higher risks may have the potential for higher returns, but they also have a greater chance of losing money. Therefore, investors who take on greater risk may expect a higher reward for their capital. Premium refers to an additional payment made to investors above and beyond their expected return. This may be offered to incentivize investment or to reward investors who are willing to take on greater risk or tie up their capital for a longer period of time. In summary, the reward for capital can take many forms, but it generally refers to the return that investors receive for putting their money to work in a business or investment. The specific form of the reward will depend on the type of investment and the risks involved.

The following are types of capital except:___________

Bayanin Amsa

The different types of capital include: Fixed capital, which are assets not used up in the course of production. Circulatory or Working capitals are assets which are used up in the process of production Eg. Raw materials, fuel etc Social capital is the assets provided by the government that aid production. Examples include electricity, water etc.

Saving capital is not a type of capital

If a demand curve that intersects a perfectly inelastic supply curve shift is rightward, then____________

Bayanin Amsa

A major determinant of the demand for a luxury good is____________?

Bayanin Amsa

The diagram below represents a production function. At which of the points does diminishing returns set in __________

Bayanin Amsa

Diminishing returns set in at point T in the production function. In a production function, adding more units of input (such as labor or capital) typically leads to an increase in output at a certain rate. However, as the amount of input increases beyond a certain point, the rate of output increase begins to decline. This is known as the law of diminishing returns. In the diagram, points R and S represent the increasing phase of the production function where output increases at an increasing rate as more input is added. However, at point T, the rate of increase in output begins to slow down, indicating that the law of diminishing returns has set in. Beyond point T, adding more input will result in smaller increases in output, and may even cause a decrease in output if the input becomes too excessive, as shown by point V. Therefore, point T is where diminishing returns set in, indicating the optimal level of input for maximum output.

The main concern of economists is to________

Bayanin Amsa

Economics seeks to study the relationship between ends and means. Ends are unlimited while the means are limited. Scarcity means resources are limited in relation to the ends. Economics therefore seek is concerned with allocating limited resources among the competing and unlimited wants.

When a variable is associated with time period, it is_____________

Bayanin Amsa

From the diagram shown, the optional point of production is_____________?

The Economic Commission for Africa was set up by the_________

Bayanin Amsa

The Economic Commission for Africa (ECA) was set up by the United Nations (UN) in 1958. The ECA is one of the UN's five regional commissions and it was established to promote economic and social development in Africa. The ECA's primary objective is to provide research and policy analysis, as well as technical assistance, to African governments, with the goal of supporting their efforts to achieve sustainable and inclusive economic growth. The ECA also works to promote regional integration and cooperation among African countries, as well as to foster partnerships with other regions of the world. Therefore, the correct answer is the UNO.

An ad valorem tax is imposed on_____?

Bayanin Amsa

An ad valorem tax is imposed on the value of a commodity. This type of tax is calculated as a percentage of the value of a product, rather than a fixed amount. For example, if a product is worth $100 and the ad valorem tax rate is 10%, the tax would be $10. The word "ad valorem" is Latin for "according to value". Ad valorem taxes are commonly used on consumer goods, such as clothing or electronics, and are applied at the point of sale. The purpose of this tax is to raise revenue for the government and to potentially regulate certain products by making them more expensive.

The privatization of public enterprises will lead to efficient management of resources in the economy. This statement can best be described as_____________

Bayanin Amsa

Taxes and government expenditures are instruments of____________

Bayanin Amsa

Taxes and government expenditures are instruments of fiscal policy. Fiscal policy refers to the government's use of its spending and taxation powers to influence the economy. By adjusting the level of taxes and government spending, the government can influence the level of economic activity and control inflation. For example, if the government wants to stimulate economic growth, it may lower taxes and increase government spending. This increases consumer spending and investment, which can boost economic activity. On the other hand, if the government wants to slow down inflation, it may raise taxes and decrease government spending, which can reduce consumer spending and slow down economic growth. In summary, fiscal policy is a crucial tool used by governments to manage their economies and maintain economic stability.

In an open economy, the GNP is measured as_____________?

Bayanin Amsa

In an open economy, GNP (Gross National Product) is measured as: C + I + G + (X - M), where: - C represents private consumption expenditures by individuals and households. - I represents gross investment by businesses, such as spending on capital goods like machinery, buildings, and equipment. - G represents government spending on goods and services. - X represents exports, which are goods and services produced domestically and sold to foreign countries. - M represents imports, which are goods and services produced in foreign countries and purchased domestically. The formula above takes into account both domestic and foreign economic activities. The net difference between exports (X) and imports (M) is included to determine the impact of international trade on the economy. Therefore, by using the formula C + I + G + (X - M) to measure GNP in an open economy, we can get a better understanding of the overall economic activity, including the impact of international trade on the economy.

If the standard deviation of a given data is 8.2, find its variance_______________

Bayanin Amsa

The variance of a given data is the square of the standard deviation. Therefore, if the standard deviation of a given data is 8.2, the variance can be calculated as follows: Variance = Standard deviation^2 Variance = 8.2^2 Variance = 67.24 So, the variance of a given data with a standard deviation of 8.2 is 67.24.

The number of people who are qualified to work and who offer themselves for employment is called____________?

Bayanin Amsa

The term used to describe the number of people who are qualified to work and who offer themselves for employment is called the "Working Population". The working population refers to individuals who are of working age and are either employed or actively seeking employment. This group of people is considered to be the supply of labor in the economy and is an important factor in determining the overall health and stability of the labor market. It's important to note that the working population can be influenced by various factors such as migration, education levels, and the availability of job opportunities. Understanding the size and composition of the working population can provide valuable insights into the current state of the labor market and can inform decisions related to economic and labor policies.

From the graph above the consumer will attain equilibrium at point_______________

Bayanin Amsa

The two major types of international trade are Bilateral trade and?

Bayanin Amsa

The two major types of international trade are bilateral trade and multilateral trade. Bilateral trade refers to the exchange of goods and services between two countries. It involves the negotiation and agreement of terms and conditions between two parties, and it usually results in a trade surplus or deficit for each country. On the other hand, multilateral trade involves the exchange of goods and services among three or more countries. This type of trade is governed by international trade agreements, such as the World Trade Organization, and aims to promote free trade and economic cooperation among member countries. In summary, bilateral trade involves trade between two countries, while multilateral trade involves trade among three or more countries and is governed by international trade agreements.

Which of the following is an invisible item?

Bayanin Amsa

The invisible item in the list is "Banking services". In economics, visible items are tangible goods that can be physically seen and touched, while invisible items are intangible services that cannot be physically seen or touched. Petroleum services, processed rice, and processed milk are all visible items because they are tangible goods that can be seen, touched, and measured. On the other hand, banking services are intangible and cannot be physically seen or touched. Examples of banking services include providing loans, managing savings accounts, facilitating transactions, and offering financial advice. Therefore, banking services are considered an invisible item because they are intangible and cannot be physically seen or touched.

Occupational distribution of information is mainly influenced by___________

Bayanin Amsa

Occupational distribution of population refers to the classification of the working population into different types of work they engage in. The occupational distribution in any population is influenced by factors which includes: The level of education, Availability of natural resources, The level of technology, The type of production activities.

Utility is the satisfaction derived from____________

Bayanin Amsa

Utility is an economic term introduced by Daniel Bernoulli referring to the total satisfaction received from consuming a good or service.

The mean is the best measure of central tendency because it__________

Bayanin Amsa

The mean is considered the best measure of central tendency because it is a balancing point in an observation. Central tendency refers to the tendency of data to cluster around a particular value in a distribution. The three measures of central tendency are mean, median, and mode. The mean is the arithmetic average of a set of data and is calculated by summing all of the values and dividing by the number of values in the set. The mean is the balancing point in an observation because it takes into account all the values in a set of data and calculates their average. It is the sum of all the values in the set divided by the total number of values. Because the mean is based on all the values in the data set, it is less likely to be affected by extreme values (outliers) than other measures of central tendency, such as the median or mode. In addition to being a balancing point in an observation, the mean has several other advantages as a measure of central tendency. For example, it is easy to calculate and is a useful tool for comparing different data sets. It can also be calculated from incomplete data, which is not the case with other measures of central tendency. Overall, the mean is the best measure of central tendency because it is a balancing point in an observation and takes into account all the values in a data set, making it less likely to be influenced by extreme values.

An economy in which both the public and private sectors contribute to economic growth is a__________?

Bayanin Amsa

The correct answer is a mixed economy. A mixed economy is an economic system that combines elements of both the public (government) and private sectors. In a mixed economy, the government and private businesses work together to create economic growth and promote social welfare. In a mixed economy, the government is responsible for providing essential services such as healthcare, education, and infrastructure. The private sector, on the other hand, is responsible for creating goods and services that meet the demands of the market. This type of economy allows for the benefits of both capitalism (private enterprise) and socialism (public enterprise) to coexist. It allows the government to regulate and control certain aspects of the economy, while still allowing the private sector to operate and innovate freely. Many modern economies around the world are considered mixed economies, including the United States, Canada, and the United Kingdom.

Efficiency of labour in a country is determined by the following except the____________

Bayanin Amsa

Efficiency of labour may be defined as the ability of labour to increase output without increasing the quantity of labour. Increase in efficiency is usually expressed in terms of increase in output of labour within a shorter period of time without any fall in the quality of goods and services produced. Factors which affect efficiency of labour include Education and training, attitude to work, working conditions of workers. However, total population is not a factor that affects efficiency of workers.

What is the median of the distribution?

Bayanin Amsa

When a group data is involved, cumulative frequency is used. The formula will be: Median=[(N+1)/2]th

  For member of odd number items. That is, where N is odd

  Median=([N/2]th + [N/2 + 1]th)/2

  For member of odd number items. That is, where N is odd

  Solution:

  From the table, there are 20 members as indicated by the cumulative frequency. Since the members are odd (10) the median age will be ([N/2]th + [N/2 + 1]th)/2

  Median=([10/2]th + [10/2 + 1]th)/2

  =(5th + 6th)/2

  The 5th member is 3 and the 6th member is on 3

  Median=(3 + 3)/2

  =6/2

  Median = 3

In other to enhance the utility of a particular commodity, it was moved from a place where it has little utility to another area where its utility is higher. This form of utility is referred to as?

Bayanin Amsa

The form of utility that refers to the enhancement of a commodity's usefulness by moving it from a place where it has little utility to another area where its utility is higher is called "place utility." For example, a bottle of water may have low utility in a store shelf where there is an abundance of water, but it would have a higher utility in a desert where water is scarce. By moving the water bottle from the store shelf to the desert, the place utility of the water bottle is increased. On the other hand, marginal utility refers to the additional satisfaction or benefit that a person derives from consuming an extra unit of a good or service, while form utility refers to the value added to a commodity by transforming it into a more useful form, such as processing raw materials into finished products. Total utility, on the other hand, refers to the overall level of satisfaction or benefit that a person derives from consuming a particular quantity of a good or service.

When a union is composed of workers with the same skill , it is called____________

Bayanin Amsa

When a union is composed of workers with the same skill, it is called a craft union. This means that the union represents workers who have the same type of training or expertise in a particular craft or trade. For example, a union of electricians, plumbers, or carpenters would be considered craft unions. These workers often have specific skills that are honed through years of training and experience, and the craft union helps to protect their interests, such as negotiating better wages, benefits, and working conditions. By focusing on a specific skill, craft unions can advocate for their members' unique needs and ensure that they receive fair treatment in the workplace.

As a factor of production, the reward for land is?

Bayanin Amsa

The reward for land as a factor of production is rent. Rent is the payment made by a tenant or user of land to the owner of the land in exchange for the right to use the land. Land, as a factor of production, refers to the natural resources such as water, air, forests, minerals, and other resources that are used in the production process. Unlike labor and capital, land is considered to have a fixed supply, which means that its availability is limited. Therefore, the price of land is determined by the demand for it, which is influenced by factors such as location, natural resources, and economic activity. In summary, the reward for land is rent, which is the payment made by a tenant or user of land to the owner of the land in exchange for the right to use the land.
