Answer:
Beta of a security is the covariance of the security return with the return on the market portfolio divided by variance of the market return.
The correct answer is C
Explanation:
Beta of a security is calculated as covariance (Ri,Rm) divided by Variance of the market return. Beta is used for measuring the systematic risk of a security.
Answer:
Just-in-time inventory management
Explanation:
Just-in-time or JIT is an inventory management approach that encourages the purchase of materials only when they are needed in the production process. The JIT approach eliminates the need for storing large quantities of material for future productions. The acquisition of materials is aligned with the production process.
By adopting JIT, a business saves on inventory costs as materials are not purchased in bulk. Wastage that results from the storage of material is also eliminated. The success of JIT depends on management ability to forecast sales accurately and working with reliable suppliers.
Answer:
If the demand curve for a life-saving medicine is perfectly inelastic, then a reduction in supply will cause the equilibrium price to <u>rise and the equilibrium quantity to stay the same</u>.
Explanation:
Perfectly inelastic demand curve indicates the quantity demanded for the life-saving medicine remains the same or does not change in response to a change in price.
Since a part of the law of supply states that the lower the quantity supplied, the higher the price; a reduction in the supply of the life-saving medicine will increase its price.
The combining effect of the two above will lead to an increase in the equilibrium price while the equilibrium quantity will remain the same as it will not respond to the change in price.
The attached graph explains this more clearly. In the graph, the demand curve DD is used to represent the perfectly inelastic demand curve for the life-saving medicine. Therefore, the quantity remains at q no matter the changes, either increase or decrease, in price. Movement from the supply curve S1 to S2 indicates a reduction in supply of the life-saving medicine which causes an increase in the equilibrium price from Po to P1 while the equilibrium quantity stays at q.
This therefore shows that if the demand curve for a life-saving medicine is perfectly inelastic, then a reduction in supply will cause the equilibrium price to <u>rise and the equilibrium quantity to stay the same</u>.
Answer:
Foreign exchange
Explanation:
The process of converting the currency of one country to another is known as foreign exchange or Forex. Converting or exchanging to a particular currency is buying that currency. One needs to have their home currency or any other currency to convert it to the desired currency.
If both currencies have equal strengths, then one unit of a currency should exchange with one unit of the other. The exchange rate would be one. Since currencies have different strengths, they convert or exchange at different rates.
