This example follows the analysis in Michael Todaro's book, Economic Development in the Third World (3rd edn, pp. 197-200) where he tries to establish which of three variables (GNP per capita, the growth rate per capita, or income inequality) is most important in determining a country's birth rate. (This analysis has been dropped from later editions of Todaro's book.) The analysis is instructive as an example of correlation and regression techniques in a number of ways. First, the question is an important one it was discussed at the UN International Conference on Population and Development in Cairo in 1995. It is felt by many that reducing the birth rate is a vital factor in economic development (birth rates in developed countries average around 12 per 1000 population, in developing countries around 30). Second, Todaro uses the Table 7.1 Todaro's data on birth rate, GNP, growth and inequality Table 7.1 Todaro's data on birth rate, GNP, growth and inequality Birth rate

As always, the bull market gave birth to those who envisioned much higher stock prices. In 1999, two economists, James Glassman and Kevin Hassett, published a book entitled Dow 36,000. They claimed that the Dow Jones Industrial Average, despite its meteoric rise, was still grossly undervalued, and its true valuation was nearly three times higher at 36,000. They incorrectly asserted that the theoretical underpinning for their analysis came from my book Stocks for the Long Run Since I showed that nominal (nonindexed) bonds were as risky as stocks over long horizons, they improperly claimed that stock prices should rise sufficiently
1980s where loopholes in lending agreements were exploited by firms, banks and bondholders began playing more active roles in management. 3. Market Innovations Markets often come up with innovative solutions to problems. In response to the corporate governance scandals in 2002 and 2003, Institutional Shareholder Services began scoring corporate boards on independence and effectiveness and selling these scores to investors. After the accounting scandals of the same period, the demand for forensic accounting, where accountants go over financial statements looking for clues of accounting malfeasance, increased dramatically. The bond market debacles of the 1980s gave birth to dozens of innovative bonds designed to protect bondholders. Even in the area of social costs, there are markets that have developed to quantify the cost. Note that we have not mentioned another common reaction to scandal, which is legislation. While the motives for passing new laws to prevent future excesses may be...
Decreased vision may result from many diseases, injuries or abnormal development of parts of the eye from before birth. The most common causes of adult visual impairments are uncontrolled diabetes, glaucoma, cataracts or macular degeneration. The most common causes of visual impairments in children are those dating from birth, such as congenital cataracts, retrolental fibroplasia and eye malformations like phthisis bulbi. Also, uncontrolled diabetes can cause retin-opathy in children, just as it can in adults. In both children and adults, some drugs used to treat noneye diseases can damage the retina.
The critical value of the F distribution at the 5 significance level, with v1 1 and v2 10, is F *10 4.96. The test statistic exceeds this, so the regression as a whole is significant. It is better to use the regression model to explain the birth rate than to use the simpler model which assumes all countries have the same birth rate (the sample average). (a) For the regression of the birth rate on the income ratio, calculate the standard errors of the coefficients and hence construct 95 confidence intervals for both.
As we have said above, each person within an organization will be subject to a number of cultural influences including national and business cultures. Which has the greatest influence will depend on their relative strengths and circumstances. In the business environment we would expect the business culture to prevail but this will only be the case where there is no conflict with the national culture. This is because national cultures are generally more important to us. This is not surprising given that national cultural traits are something that are programmed into us almost from birth, but business cultures are only programmed later in life. Unless we stay in the same organization for all our working life, something which is becoming less likely, we will be subject to a variety of business cultures as we move from organization to organization. Each organizational culture will have less and less influence. Hofstede discusses this difference between national and business cultures in...
We also introduce a new example in this section, estimating a demand equation for imports into the UK over the period 1973-2003. There are a number of reasons for this switch, for we could have continued with the birth rate example (you are asked to do this in the exercises). First, it allows us to work through a small 'research project' from beginning to end, including the gathering of data, data transformations, interpretation of results, etc. Second, the example uses time-series data and this allows us to bring out some of the particular issues that arise in such cases. Time-series data do not generally constitute a random sample of observations such as we have dealt with in the rest of this book. This is because the observations are constrained to follow one another in
Thus, our analysis is based on a subgroup of our target population described at the beginning. Those who died before 1993 and were alive after 1993 are not included in the study. Yet, the extreme life spans within the subgroup are governed by the same distribution as those of the entire population under the condition that the birth rate was nearly homogeneous during the relevant period. This idea can be made rigorous by a thinning argument within the point process framework, see 43 , pages 68 and 69. For that purpose, consider uniformly distributed dates of birth V over the relevant time period and add life spans Xi. The thinning random variable is defined by Ui I(1993 Vi + Xi 1994).
Turning next to the other source of systemic risk, the prime example of a breakdown in the payment system was the June 1974 failure of Bankhaus Herstatt, a small German bank active in the foreign exchange market. The bank was shut down by noon, U.S. time, after having received payments in German marks. In exchange, the counterparty banks were due to receive payment in the same afternoon in U.S. dollars. These payments never came, however, creating substantial losses and a serious liquidity squeeze for counterparties. This event caused severe disruption in the payment system and was perhaps the most extreme shock experienced in the foreign exchange market. What has become known as Herstatt risk has led to a concerted effort by bank regulators to try to avoid such situations, which ultimately gave birth to the Basel Committee on Banking Supervision (BCBS).
Cerebral palsy (CP) is not a specific disease, but refers to any nervous system problem dating from the time of birth that is not progressive and results from damage to the developing brain. The kinds of things that can cause brain damage are varied and include infection, toxins, birth trauma, genetic defects and asphyxia. Cerebral palsy may involve either physical or mental abnormalities. CP can result in a wide range of neurological impairments, including epilepsy, mental retardation, paralysis (paraplegia, hemiplegia or quadriplegia), spas-ticity, ataxia and athetosis, as well as visual, hearing and speech problems. Additionally, mental problems such as emo
The basic nature of the pensions crisis facing a range of economies was identified in Section 22.3 increasing longevity and the decline in the birth rate are combining to increase the dependency ratio. Without major reform or an un-acceptably high increase in tax rates, the pension programs will either go into deficit or pay a much reduced pension. A variety of reforms have been proposed in response to this crisis. Some of these are now briefly reviewed.
The generic name of dual-currency bonds hides many different variations which are difficult to characterize in detail. These variations on the same basic concept have given birth to specific names like Index Currency Option notes (ICON), foreign interest payment bonds (FIPS), forex-linked bonds, heaven and hell bonds, to name but a few. Despite this diversity it is, however, possible to attempt a broad-brush classification of the various types of dual-currency bonds.
Stockmarkets have always been volatile, but such volatility in currencies, interest rates, bonds and even loan prices was something new. With so many new variables it was becoming increasingly important for companies and banks to find ways of protecting themselves against extreme fluctuations. This simple need gave birth to a highly complex activity the creation, selling and trading of financial derivatives.
7In 2007, the consolidation process experienced a further acceleration. The two largest operations gave birth to two big players, Intesa-San Paolo and Unicredit Group, with a national market share equal, respectively, to 20.2 and 17.3 and with a significant presence in Europe (Bank of Italy 2008). However, consolidation also affected the world of cooperative banks (Banche Popolari), with the creation of two very large mutual bank groups, Banco Popolare and UBI Banca, both with a large geographical spread with a network of 2,000 branches each.
Degeneration of the lens of the eye so that light cannot easily pass through it. Most cataracts are related to aging, but some date from birth (congenital cataracts) or from the use of medication, such as the chronic use of steroid drugs. Cataracts are sometimes described by doctors as a lens opacity.
The relationships graphed in Figure 7.1 can first be summarised numerically by measuring the correlation coefficient between any pair of variables. We illustrate this by calculating the correlation coefficient between the birth rate (B) and growth (G), though we also present the results for the other cases. Just as the mean is a number that summarises information about a single variable, so the correlation coefficient is a number which summarises the relationship between two variables.
Birth rate Birth rate is close (but not identical) to the actual birth rate of 30. The difference reflects the absence of perfect correlation between the two variables. The difference between the actual value, Y, and the predicted value, Z, is called the error or residual. It is labelled e in Figure 7.4. Why should such errors occur The relationship is never going to be an exact one for a variety of reasons. There are bound to be other factors besides growth which affect the birth rate (e.g. the education of women) and these effects are all subsumed into the error term. There might additionally be simple measurement error (of Y) and, of course, people do act in a somewhat random fashion rather than follow rigid rules of behaviour. Why not include these factors explicitly On the face of it this would seem to be an improvement, making the model more realistic. However, the costs of doing this are that the model becomes more complex, calculation becomes more difficult (not so important...
In this chapter we look at two basic explanations of real-life happenings. First of all, within the same market logic, biases occur which may explain why companies borrow funds, and why they stop at a certain level. The fundamental factors from which these biases spring are taxes, financial distress and agency costs. Their joint analysis will give birth to the tradeoff model .
Our contribution is to introduce a class of self-affecting models for portfolio loss that incorporate event feedback and the negative dependence between default and recovery rates. These dynamic models lead to computationally tractable valuation and hedging problems for portfolio credit derivatives. We follow the intensity-based top-down approach described in Giesecke and Goldberg (2005). Here the portfolio loss process is specified in terms of a default rate and a distribution for loss given default, and random thinning is used to estimate hedge ratios. Extant intensity specifications typically neglect the dependence between default and recovery rates. Examples include Davis and Lo (2001), who consider a homogeneous portfolio in which an event ramps up the intensity by a fixed factor for an exponential time. Ordinary differential equations govern the distribution of the default process. A more recent example is Giesecke and Tomecek (2005), where a stochastic time change is applied to...
Under the new plan, both external and internal candidates were considered for available positions, which necessitated a new emphasis on market pricing. External hires needed to have market-based pay structures. This gave birth to our market-pricing project, said Graebner.
American Telephone and Telegraph Co. was the largest company in the world when it joined the S&P 500 Index in 1957, and it remained that way until 1975. The company boasted a market value of 11.2 billion in 1957, a capitalization that would rank in the bottom 200 of the S&P 500 firms in 2007. The telephone monopoly known as Ma Bell was broken up in 1984, giving birth to the Baby Bell regional providers. But the
The basis of the pensions crisis is three-fold. Firstly, most developed economies have witnessed a reduction in their birth rates. Although immigration has partially offset the effect of this in some countries, there has still been a net effect of a steady reduction in the addition of new workers. The second effect is that longevity is increasing so that people are on average living longer. For any given retirement age, this is increasing the number of retired. Thirdly, there is also a tendency for the retirement age to fall.
