Diminishing Marginal Returns Quotes

The scholars who research happiness suggest that more money stops making people happier at a family income of around seventy-five thousand dollars a year. After that, what economists call “diminishing marginal returns” sets in. If your family makes seventy-five thousand and your neighbor makes a hundred thousand, that extra twenty-five thousand a year means that your neighbor can drive a nicer car and go out to eat slightly more often. But it doesn’t make your neighbor happier than you, or better equipped to do the thousands of small and large things that make for being a good parent.

We reach the point of diminishing marginal predictive returns for knowledge disconcertingly quickly,” Tetlock writes. “In this age of academic hyperspecialization, there is no reason for supposing that contributors to top journals—distinguished political scientists, area study specialists, economists, and so on—are any better than journalists or attentive readers of The New York Times in ‘reading’ emerging situations.” The

the person who acquires more knowledge develops an enhanced illusion of her skill and becomes unrealistically overconfident. “We reach the point of diminishing marginal predictive returns for knowledge disconcertingly quickly,

But those with the most knowledge are often less reliable. The reason is that the person who acquires more knowledge develops an enhanced illusion of her skill and becomes unrealistically overconfident. “We reach the point of diminishing marginal predictive returns

Those who know more forecast very slightly better than those who know less. But those with the most knowledge are often less reliable.

It is suggested that the increased costs of sociopolitical evolution frequently reach a point of diminishing marginal returns. This is to say that the benefit/investment ratio of sociopolitical complexity follows the marginal product curve … After a certain point, increased investments in complexity fail to yield proportionately increasing returns. Marginal returns decline and marginal costs rise. Complexity as a strategy becomes increasingly costly, and yields decreasing marginal benefits.

Principal Management Corporation, the manager of the LargeCap Value Fund, actually provides no investment management services, focusing instead on “clerical, recordkeeping and bookkeeping services.” Responsibility for the day-in and day-out portfolio management rests with a subsidiary of Alliance Capital Management, Bernstein Investment Research and Management.17 The fee arrangement between Principal and Bernstein involves only a portion of Principal’s take from its investors. For the year ended December 31, 2003, Principal’s no-load Class B shares bore the burden of a 2.51 percent expense ratio, as detailed in Table 8.7. Investors paid a 12b-1 fee of 0.91 percent, other expenses of 0.85 percent and a management fee of 0.75 percent. Principal’s fees all but guarantee that investors will fail to generate satisfactory returns. The management fee arrangement between Principal and Bernstein provides clues to the economies of scale available in the money management industry. At asset levels below $10 million, of the 0.75 percent management fee, 0.60 percent goes to Bernstein and 0.15 percent goes to Principal. As assets under management increase, Bernstein’s fee share decreases and Principal’s fee share increases. At the final break point of $200 million in assets, of the scale-invariant 0.75 percent fee, Bernstein receives 0.20 percent and Principal receives 0.55 percent. The fee structure clearly illustrates scale economies in the investment management business. Bernstein, the party responsible for the heart of the portfolio management process, earns fees that diminish (with increases in assets under management) from 0.60 percent of assets to 0.20 percent of assets. Since Bernstein’s work changes not at all as asset levels increase, the reduction in marginal charges makes sense. It makes no sense that Principal’s mutual-fund clients accrue no benefits from economies of scale. Total expenses incurred by investors remain at 2.51 percent regardless of portfolio size. As Bernstein’s management fee declines, Principal’s management fee increases. For assets above $200 million Principal adds a management fee of 0.55 percent to other fees of 1.76 percent, bringing the egregious total to 2.31 percent for Principal and 0.20 percent for Bernstein. In this topsy-turvy world, Principal earns a marginal management fee of 0.55 percent for performing back-office functions, while Bernstein earns a marginal management fee of 0.20 percent for making security-selection decisions. As scale increases, Bernstein earns less while Principal takes more.
