Abstract: We analyze the dynamics of banks' regulatory capital ratios. Using monthly regulatory data of large German banks, we estimate the target level and the adjustment speed of the capital ratio for each bank separately. There exists a target level for a substantial percentage of banks. Unlike with panel regressions, we can estimate individual adjustment speeds and find large variation across banks. Adjustments on the liability side are most effective, although adjustment rates on the asset side are higher. Private commercial banks (neither state-owned nor cooperative) and banks with a high level of proprietary trading are more likely to adjust their capital ratio tightly. Banks with a target capital ratio compensate for low target ratios with low asset volatilities and high adjustment speeds. They seem to care mainly about the resulting probability to comply with the regulatory minimum. Assuming low variation of this probability explains most of the large cross-sectional variation of bank capital.
A ratio is a number or pair of numbers representing the size of one quantity relative to another as a part-to-whole or part-to-part comparison. Ratios are common in chemistry and are encountered in many forms. Fractions and percentages are specific types of ratios. Chemical formulas are specialized ratios.
A ratio is a way of showing proportions of amounts. For example, if there are double the number of green marbles compared with the number of yellow marbles, then we can show this by writing 2:1. This would be read as: 'the ratio of green marbles to yellow marbles is two to one'. Two parts of the marbles are green and one part is yellow, but: what is 'part(s) of' as a fraction? It's easy: 2 + 1 = 3, so 2⁄3 are green, and 1⁄3 is yellow.
You would deal with other ratios in a similar way. This 11-plus Maths quiz is our easiest of the two on ratios. Give it a go and don't move on until you've got all ten questions correct. You might find having some paper and a pencil a handy addition. That way, you can write out (or even draw) the ratios.
#CarnegieConf speaker Oli Gardner defines it as "the ratio of links on a landing page to the number of campaign conversion goals. In an optimized campaign, your attention ratio should be 1:1. Because every campaign has one goal, every corresponding landing page should have only one call to action-one place to click."
Proportions are built from ratios. A "ratio" is just a comparison between two different things. For instance, someone can look at a group of people, count noses, and refer to the "ratio of men to women" in the group. Suppose there are thirty-five people, fifteen of whom are men. Then the ratio of men to women is 15 to 20.
Ratio problems are often solved by using proportions. A proportion is an equation formed with two ratios that are equal. One method for solving a proportion problem is to find the appropriate equivalent ratio. We could have solved the original problem by setting up a proportion and then finding what the equivalent fraction would have to be.
A ratio compares two quantities in terms of multiplication. For example, suppose that there are 10 boys and 15 girls in a classroom. One way, not using ratios, to compare these quantities would be to say that there are 5 more girls than boys in the classroom. To employ a ratio, we say that the ratio of boys to girls is 10 to 15, or 2 to 3. In other words, for every 2 boys in the classroom, there are 3 girls.
4 moles of Al react with 3 moles of oxygen, producing 2 moles of Al2O3. If we take 2 moles (instead of 4) of Al we will get only half the product - so there will be only 1 mole of Al2O3 produced. We can write the reaction equation together with amounts of substances (writing amounts of substances below their formulas):
The interactive white board Teacher Tool for this lesson is available on our website under Resources /teachertools Students use a ratio table to record equivalent measurement ratios in the context of a recipe. This DreamBox lesson engages students in mental multiplication, division and proportional reasoning as they use scale factors and number relationships to generate equivalent ratios.
Now that you've got your hands on the financial statements you'll be working with, it is important to know exactly what to do with this data and how to interpret it. By itself, a ratio is not very useful, but when compared to other companies in the same economic sector, to the broader market, or changes over time - then ratios become a powerful tool to evaluate how attractive a potential investment might be.
Ratios occur in mixing things - such as concrete which is made of cement, sand and gravel in a definite ratio. For example, a ratio of 1:3:4 would mean that no matter what volume of concrete you have, 1 part is cement, 3 parts is sand and 4 parts is gravel. An alternative way of stating this is to say that $\frac18$ is cement, $\frac38$ is sand and $\frac48$ $\left(\mboxi.e. \frac12\right)$ is gravel.
Be aware of how ratios are used. Ratios are used in both academic settings and in the real world to compare multiple amounts or quantities to each other. The simplest ratios compare only two values, but ratios comparing three or more values are also possible. In any situations in which two or more distinct numbers or quantities are being compared, ratios are applicable. By describing quantities in relation to each other, they explain how chemical formulas can be duplicated or recipes in the kitchen expanded. After you get to understand them, you will use ratios for the rest of your life. 1
U.S. banks hold significantly more equity capital than required by their regulators. We test competing hypotheses regarding the reasons for this excess” capital, using an innovative partial adjustment approach that allows estimated BHC-specific capital targets and adjustment speeds to vary with firm-specific characteristics. We apply the model to annual panel data for publicly traded U.S. bank holding companies (BHCs) from 1992 through 2006, an extended period of increasing bank capital that ended just before the subprime credit crisis of 2007-2008. The evidence suggests that BHCs actively managed their capital ratios (as opposed to passively allowing capital to build up via retained earnings), set target capital levels substantially above well-capitalized regulatory minima, and (especially poorly capitalized BHCs) made rapid adjustments toward their targets.
As long as a company has positive earnings, the P/E ratio is calculated this way (a company with no earnings, or one which is losing money, has no P/E ratio). The stock price per share is set by the demand and supply prevalent in the stock market, and the earnings per share value will vary, depending on the company's financials and which earnings variant is used. Typically, EPS is taken from the last four quarters ( trailing EPS ; referred to as TTM for trailing twelve months), but it can also be taken from the estimates of earnings expected over the next four quarters ( forward EPS ) or some other variation.
Often, students learn how to solve proportions by memorizing the steps, but then they also forget those in a flash after school is over. They may remember faintly something about cross multiplying, but that's as far as it goes. How can we educators help them learn and retain how to solve proportions?
The ratios are basically mathematical fractions expressed differently. In maths, ratios express the volume of quantities relative to each other. The ratio is said to be a relation between two quantities expressed algebraically. The Ratio represents the number of times the first quantity is of second one. The ratio $\frac3510$ may be simplified and written as $\frac72$ or $\frac3510$ = $\frac72$. It implies that 35 is $\frac72$ times of 10.
Sometimes it is useful to write a ratio in another way. For example, there are 8 cups of strawberries added to a fruit salad for every 16 cups of other fruits. This is an 8:16 ratio of strawberries to other fruits. However, it can also be represented as 1 :2. So if we add one cup of strawberries we can add two cups of other fruits and keep the same mixture in a smaller amount.
So when there are 10 boys, there must be 20 girls. Note that we wrote the ratios in the proportion in the fraction form and that the second ratio must be in the same order as the first ratio. In this case the numerals representing the number of girls are in the numerators and the numerals representing the number of boys are in the denominators.
The unit rate of 120 students for every 3 buses is 40 students per bus. You could also find the unit rate by dividing the first term of the ratio by the second term. When prices are expressed as a quantity of 1, such as $25 per ticket or $0.89 per can, they are called unit prices. If you have a multiple-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the single-unit price, divide the multiple-unit price by the number of units.
