Even the World Bank has contributed a few studies, notably, in June, "Child Labor: The Role of Income Variability and Access to Credit Across Countries" authored by Rajeev Dehejia of the NBER and Roberta Gatti of the Bank's Development Research Group. Abusive child labor is abhorrent and should be banned and eradicated. All other forms should be phased out gradually. Developing countries already produce millions of unemployable graduates a year - 100,000 in Morocco alone. Unemployment is rife and reaches, in certain countries - such as Macedonia - more than one third of the workforce. Children at work may be harshly treated by their supervisors but at least they are kept off the far more menacing streets. Some kids even end up with a skill and are rendered employable. XXIII. The Myth of the Earnings Yield In American novels, well into the 1950's, one finds protagonists using the future stream of dividends emanating from their share holdings to send their kids to college or as collateral. Yet, dividends seemed to have gone the way of the Hula-Hoop. Few companies distribute erratic and ever-declining dividends. The vast majority don't bother. The unfavorable tax treatment of distributed profits may have been the cause. The dwindling of dividends has implications which are nothing short of revolutionary. Most of the financial theories we use to determine the value of shares were developed in the 1950's and 1960's, when dividends were in vogue. They invariably relied on a few implicit and explicit assumptions: 1. That the fair "value" of a share is closely correlated to its market price; 2. That price movements are mostly random, though somehow related to the aforementioned "value" of the share. In other words, the price of a security is supposed to converge with its fair "value" in the long term; 3. That the fair value responds to new information about the firm and reflects it - though how efficiently is debatable. The strong efficiency market hypothesis assumes that new information is fully incorporated in prices instantaneously. But how is the fair value to be determined? A discount rate is applied to the stream of all future income from the share - i.e., its dividends. What should this rate be is sometimes hotly disputed - but usually it is the coupon of "riskless" securities, such as treasury bonds. But since few companies distribute dividends - theoreticians and analysts are increasingly forced to deal with "expected" dividends rather than "paid out" or actual ones. The best proxy for expected dividends is net earnings. The higher the earnings - the likelier and the higher the dividends. Thus, in a subtle cognitive dissonance, retained earnings - often plundered by rapacious managers - came to be regarded as some kind of deferred dividends.
