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.

The formation of cartels or monopolies in order to obtain better bargaining or deals from other countries is characteristic of countries producing the same or identical goods. When multiple countries produce the same or very similar goods, they may face competition from each other in the global marketplace. This competition can lead to lower prices and lower profits for all the countries involved. To avoid this, these countries may form a cartel or monopoly by agreeing to work together to limit production or fix prices. By doing so, they can increase their bargaining power and negotiate better deals with other countries or buyers. For example, the Organization of the Petroleum Exporting Countries (OPEC) is a cartel made up of oil-producing countries that work together to regulate the supply and price of oil in the global market. By working together, they can maintain higher prices for their oil and negotiate better deals with buyers. Overall, the formation of cartels or monopolies can be a way for countries producing similar goods to gain more control over the market and secure better economic outcomes for themselves.

Both statements are correct. Climate and availability of water are important factors that can affect where people choose to live. Areas with a favorable climate and a reliable source of water are often more attractive to people, leading to higher population densities in those regions. On the other hand, areas with harsh climates or limited access to water may have lower population densities. Density of population refers to the number of people living in a given area. By understanding the population density in different regions, we can get a better understanding of how densely populated an area is and how the population is distributed over the land. This information is useful in a variety of fields, including urban planning, resource management, and public health.

The transfer of public shareholding in corporations to private enterprise is called privatization. This means that the ownership and control of a company, which was previously held by the government or the public, is now transferred to a private company or individual. Privatization can take many forms, such as selling shares of a public company to private investors, selling off a state-owned enterprise to a private company, or outsourcing government services to private companies. The goal of privatization is usually to improve efficiency, increase competition, and reduce government spending. In summary, privatization refers to the transfer of ownership and control of public companies to private entities, which is done to improve the performance and efficiency of the organization.

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.

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 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 use of income and expenditure instruments or policies to control or regulate the economic activities of a country is known as Fiscal Policy. Fiscal policy involves the use of government spending and taxation to influence the economy's performance. For example, during a recession, the government may increase its spending to stimulate economic growth and create jobs. Alternatively, during a period of high inflation, the government may reduce its spending and increase taxes to reduce the amount of money in circulation and lower inflation. Fiscal policy can be used to achieve various economic objectives, such as stabilizing the economy, promoting economic growth, and reducing income inequality. It is an essential tool for governments to manage the economy and ensure its stability and growth over the long term.

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.

The coefficient of the price elasticity of supply is positive. This means that as the price of a good or service increases, the quantity of it that is supplied will increase as well. Conversely, if the price decreases, the quantity supplied will decrease. The degree to which the quantity supplied responds to changes in price is what the coefficient of the price elasticity of supply measures. A perfectly elastic supply has an elasticity of infinity, meaning that even a small change in price will result in a large change in the quantity supplied. On the other hand, a perfectly inelastic supply has an elasticity of zero, meaning that the quantity supplied does not change in response to price changes.

In the long run, all production factors are variable. This means that in the long run, a firm can adjust all of its inputs, including labor, capital, and resources, to produce the level of output it desires. Unlike the short run, where some production factors are fixed and cannot be changed, the long run allows firms to make changes to all of their inputs, such as investing in new technology or equipment, hiring or firing employees, and even moving to a new location. For example, in the short run, a bakery may only be able to increase its production by hiring more workers or working longer hours, as its oven and baking equipment are fixed. But in the long run, the bakery could invest in new, larger equipment to increase its production capacity, as well as relocate to a larger facility or even open new stores. Therefore, in the long run, all production factors can be adjusted, making them variable, while in the short run, some factors are fixed, making them less adaptable to changes in production levels.

The reduction in the value of a country's currency in relation to the value of the currencies of other nations is known as "Devaluation". When a country's currency is devalued, it means that the value of its currency has decreased compared to the currencies of other countries. This can happen for a number of reasons, including a decrease in the demand for the country's goods and services, a decrease in the country's economic growth, or a decrease in the country's foreign reserves. A devaluation makes a country's exports cheaper and more competitive on the global market, which can help boost the country's economy. However, it can also lead to higher prices for imported goods, which can negatively impact the country's consumers. In simple terms, devaluation is when a country's currency becomes less valuable compared to other currencies.

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.

To calculate the population density of Nigeria, we need to divide the total population of Nigeria by its total land area. So, Population density of Nigeria = Total population of Nigeria / Total land area of Nigeria Plugging in the values, we get: Population density of Nigeria = 180,000,000 / 923,768 sq km Solving this equation, we get: Population density of Nigeria = 195 people per sq km (rounded to the nearest whole number) Therefore, is the correct answer. Nigeria has a population density of approximately 195 people per square kilometer, which means that on average, there are 195 people living in every square kilometer of land in Nigeria. This number is relatively high compared to some other countries, but it is important to note that population density varies widely depending on factors such as geography, climate, and economic development.

The money paid per hour for work done is called a "wage rate". Wage rate is the amount of money an employee is paid for each hour of work. It's a basic unit of pay that reflects the compensation an employee receives for the time and effort they put into their job. The wage rate can be influenced by various factors, including the employee's experience, qualifications, and the type of work they do. It's important to note that wage rate is different from salary, which is a fixed amount of money paid to an employee for a set period of time, usually annually or monthly. A bonus, on the other hand, is an additional payment made to an employee in recognition of good work or as a reward for achieving a specific goal.

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.

When the elasticity of demand is zero, the demand curve is said to be perfectly inelastic. This means that a change in price will not cause any change in the quantity demanded. In other words, no matter how much the price changes, the quantity demanded will remain the same. For example, if the price of insulin for diabetes treatment were to double, people who depend on it to survive would have no choice but to continue buying the same amount. This is because they cannot reduce their consumption of insulin, and therefore, the demand for insulin is perfectly inelastic. In terms of the demand curve, a perfectly inelastic demand curve is vertical, meaning that it is a straight line perpendicular to the horizontal axis. This is because, as mentioned earlier, the quantity demanded remains constant regardless of the price. So, when graphed, the demand curve will be a straight vertical line.

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 basic economic problems of society refer to the fundamental challenges that arise from the limited availability of resources and the unlimited wants and needs of individuals and society as a whole. The three main economic problems are scarcity, choice, and opportunity cost. Scarcity refers to the limited availability of resources, such as land, labor, and capital, relative to the unlimited wants and needs of individuals and society. This means that choices must be made about what to produce, how to produce it, and for whom it should be produced. The second economic problem is choice. Because resources are scarce, individuals and societies must make choices about what goods and services to produce and consume. This requires answering questions like "what to produce," "how much to produce," "how to produce it," and "for whom to produce it." These choices have important consequences for the allocation of resources and the distribution of income and wealth. The third economic problem is opportunity cost. This refers to the cost of choosing one option over another, as measured by the value of the best alternative foregone. In other words, every time we make a choice, we give up the opportunity to do something else with those resources. This means that the cost of any choice is not only the direct cost of producing or consuming a good, but also the opportunity cost of not using those resources in some other way. In summary, the basic economic problems of society include scarcity, choice, and opportunity cost. These problems arise from the limited availability of resources relative to the unlimited wants and needs of individuals and society, and require making choices about what to produce, how to produce it, and for whom it should be produced.

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.
