Stock prices tend to ignore unexpected changes in dividend payments. Companies prefer to cut dividend payments rather than borrow money to fund a short-term cash need. Maintaining a steady dividend is a key goal of most dividend-paying companies. Share repurchases tend to increase agency costs. Short-term fluctuations in cash flows are the key factor in determining a company's dividend policy

Answers

Answer: B. Maintaining a steady dividend is a key goal of most dividend-paying companies.

Explanation:

Companies that pay dividends prefer in general, to maintain a steady dividend overtime. This does not necessarily mean that they will pay the same amount of dividend but rather that they will pay out dividends as within a certain percentage range of the net income.

Companies do not prefer to cut dividends so as not to send the wrong message so A is wrong. Share repurchases reduces agency costs so C is wrong. Short term fluctuations in cash flow are not the key favor in determining dividend policy as the company might still pay out the same regardless so this is wrong as well. Option B is the best answer.

According to the liquidity premium theory of the term structure, A. the interest rate on long-term bonds will equal an average of short-term interest rates that people expect to occur over the life of the long-term bonds plus a liquidity premium. B. buyers of bonds may prefer bonds of one maturity over another, yet interest rates on bonds of different maturities move together over time. C. even with a positive liquidity premium, if future short-term interest rates are expected to fall significantly, then the yield curve will be downward-sloping. D. all of the above. E. only A and B of the above.

Answers

Answer: D. all of the above.

Explanation:

The liquidity premium is the amount that is added to the interest rate in order to compensate investors for buying longer term and less liquid securities. This is why the interest rates on log-term bonds include a liquidity premium.

It is true that depending on preference, buyers of bonds prefer to buy one maturity over another but overall, the interest rates on different maturities move together in that an increase in the short term would see an increase in the long term.

Even if the liquidity premium is positive in order to compensate investors for longer maturities, it would not be enough to pull the interest rates up if they are falling significantly which would lead to a downward - sloping yield curve.

Answers

Answer:

a decrease in the required reserve ratio

Explanation:

The Federal Reserve utilises various strategies to control money supply to the economy. Money supply is the amount of money that is held by by the public in an economy.

The various methods used by the Federal Reserve to regulate money supply includes discount rate, reserve ratio, and open market operations.

Money supply will increase when the reserve ratio for commercial banks is decreased. This means less of their funds is required to be witheld from the public.

On the other hand an open market sale will mop up the cash in the economy, and an increase in discount rate (rate of lending to banks) will also cause a decrease in money supply.

O D. decide what each employee at a U.S. company will be paid. SUBMIT​

Answers

Answer:

A. make sure government programs can function properly.

Explanation:

Taxation can be defined as the involuntary or compulsory fees levied on individuals or business entities by the government to generate revenues used for funding public institutions and activities.

The different types of tax include the following;

1. Income tax: a tax on the money made by workers in the state. This type of tax is paid by employees with respect to the amount of money they receive as their wages or salary.

2. Property tax: a tax based on the value of a person's home or business. It is mainly taxed on physical assets or properties such as land, building, cars, business, etc.

3. Sales tax: a tax that is a percent of the price of goods sold in retail stores. It is being paid by the consumers (buyers) of finished goods and services and then, transfered to the appropriate authorities by the seller.

The main reason for government spending such as building public schools, power supply, water, development of infrastructures, etc., is to ensure and facilitate the proper functioning of all government programs.

Hence, the government of a particular country is saddled with the responsibility of spending on basic projects or programs so as to create a sustainable, growing and efficient economy for its citizens.
