Agriculture plays a dominant role in West African economies because it employs more than 50% of the total labour force in the region. In other words, a significant portion of the population in West African countries depend on agriculture for their livelihood. Additionally, there are large plantations of crops such as cocoa, groundnut, and oil palm in the region, which provide a major source of revenue for these countries. The abundance of arable land and favorable weather conditions in West Africa also make agriculture a viable and important economic activity.

Which of the following statements is not true in an inflationary period?
Detalles de la respuesta
The statement that is not true in an inflationary period is: "Wages rise simultaneously with prices." Inflation is a period when the general price level of goods and services increases continuously, resulting in a decline in the purchasing power of money. During this period, wages may increase due to increased labor demand or negotiations by labor unions, but they may not necessarily rise simultaneously with prices. Inflation is caused by various factors, such as an increase in the money supply, cost-push factors, demand-pull factors, and supply shocks. As the general price level rises, the purchasing power of money diminishes, leading to a reduction in real income for fixed income earners. Inflation also creates a situation where more money is chasing a limited quantity of goods, which results in an excess demand for goods and services over the available supply.

A shift of the demand curve to the right when the supply curve remains constant , implies that
Detalles de la respuesta
In economics, the demand curve shows the relationship between the price of a product and the quantity that consumers are willing to buy at that price. When there is a shift of the demand curve to the right while the supply curve remains constant, it means that at every price point, consumers are willing to buy more of the product. This could be due to factors such as an increase in consumer income, a change in tastes and preferences, or an increase in the availability of credit. As a result, both the price and quantity demanded will increase. Therefore, the correct answer is: "both price and quantity demanded will increase."

Detalles de la respuesta

These reasons are driven by the desire for better opportunities, safety, and a better quality of life.

Detalles de la respuesta
Choice is necessary because resources are scarce. This means that there are not enough resources available to satisfy all the wants and needs of people. As a result, people have to make choices about how to allocate the resources they have in order to best meet their needs and wants. These choices involve trade-offs, where the decision to use a resource for one purpose means that it cannot be used for another purpose. Therefore, choice is necessary in order to make the best use of the limited resources available.

Detalles de la respuesta
If over a period of time there is more money in the economy than the available goods and services, the economy is likely to experience inflation. This is because when there is too much money chasing too few goods, the prices of goods and services will rise. This can lead to a decrease in purchasing power of the currency, as it requires more money to buy the same amount of goods and services. Inflation can have negative effects on an economy, such as reducing the value of savings, decreasing investment, and causing social and political unrest.

Detalles de la respuesta
The monetary system that requires a double coincidence of wants is known as the barter system. In a barter system, goods or services are directly exchanged without the use of money. In order for a trade to occur, both parties must have what the other wants, creating a double coincidence of wants. For example, if you have a cow and want some wheat, you would need to find someone who has wheat and wants a cow. This can be difficult and time-consuming, which is why barter systems are not commonly used in modern economies.

Detalles de la respuesta
In the event of a limited liability company going into liquidation, each shareholder may lose a maximum of the amount he has invested.

Which of the following is not an argument for locating industries in rural areas?
Detalles de la respuesta
The argument that "capital is easily available in rural areas" is not a reason for locating industries in rural areas. Explanation: Capital refers to the money needed to start or invest in a business. Generally, it is easier to access capital in urban areas where there are more financial institutions, investors, and a larger economy. Rural areas may have less access to capital, which can be a challenge for starting businesses. Therefore, this argument does not support the idea of locating industries in rural areas.

Detalles de la respuesta
A movement along the demand curve for some goods is caused by a change in the price of that particular good. When the price of a good changes, it directly affects the quantity of that good that consumers are willing and able to buy. If the price of a good decreases, consumers will typically demand more of it, whereas if the price of a good increases, consumers will typically demand less of it. Changes in consumer income, tastes, the price of other goods, and population can also affect the demand for a good, but they do not cause a movement along the demand curve. Instead, they cause a shift in the demand curve itself, which represents a change in the amount of a good that consumers are willing and able to buy at any given price level.

Detalles de la respuesta
Dumping in economics refers to the practice of selling goods in a foreign market at a price below that received in the home market. This is done in order to gain a competitive advantage in the foreign market and increase market share. The purpose of dumping is to drive competitors out of the market and establish a monopoly. Dumping is generally considered an unfair trade practice, as it can cause harm to domestic producers in the foreign market. It can also lead to a race to the bottom in terms of pricing, which can be detrimental to all producers involved.
