Efficiency and effectiveness in ..
A theory of natural languages mustaccount for the many phrases and sentences which leave a nativespeaker uncertain about their grammaticality (see Chris Manning's and its discussion of the phrase ""), and there are phrases which some speakers findperfectly grammatical, others perfectly ungrammatical, and stillothers will flip-flop from one occasion to the next.
Topic: Efficiency, market failure and government intervention
Efficiency improvements push down costs at every level—from the mining of raw materials to the fabrication and transportation of finished goods to the frequency and intensity of actual use—and reduced costs stimulate increased consumption. (Coincidentally or not, the growth of American refrigerator volume has been roughly paralleled by the growth of American body-mass index.) Efficiency-related increases in one category, furthermore, spill into others. Refrigerators are the fraternal twins of air-conditioners, which use the same energy-hungry compressor technology to force heat to do something that nature doesn’t want it to. When I was a child, cold air was a far greater luxury than cold groceries. My parents’ first house—like eighty-eight per cent of all American homes in 1960—didn’t have air-conditioning when they bought it, although they broke down and got a window unit during a heat wave, when my mom was pregnant with me. Their second house had central air-conditioning, but running it seemed so expensive to my father that, for years, he could seldom be persuaded to turn it on, even at the height of a Kansas City summer, when the air was so humid that it felt like a swimmable liquid. Then he replaced our ancient Carrier unit with a modern one, which consumed less electricity, and our house, like most American houses, evolved rapidly from being essentially un-air-conditioned to being air-conditioned all summer long.

Efficiency and Effectiveness in Management Essay - …
Jevons might be little discussed today, except by historians of economics, if it weren’t for the scholarship of another English economist, Len Brookes. During the nineteen-seventies oil crisis, Brookes argued that devising ways to produce goods with less oil—an obvious response to higher prices—would merely accommodate the new prices, causing energy consumption to be higher than it would have been if no effort to increase efficiency had been made; only later did he discover that Jevons had anticipated him by more than a century. I spoke with Brookes recently. He told me, “Jevons is very simple. When we talk about increasing energy efficiency, what we’re really talking about is increasing the productivity of energy. And, if you increase the productivity of anything, you have the effect of reducing its implicit price, because you get more return for the same money—which means the demand goes up.”

Most economists and efficiency experts have come to similar conclusions. For example, some of them say that when you increase the fuel efficiency of cars you lose no more than about ten per cent of the fuel savings to increased use. And if you look at the whole economy, Schipper said, rebound effects are comparably trivial. “People like Brookes would say—they don’t quite know how to say it, but they seem to want to say the extra growth is more than the saved energy, so it’s like a backfire. The problem is, that’s never been observed on a national level.”

But troublesome questions have lingered, and the existence of large-scale rebound effects is not so easy to dismiss. In 2004, a committee of the House of Lords invited a number of experts to help it grapple with a conundrum: the United Kingdom, like a number of other countries, had spent heavily to increase energy efficiency in an attempt to reduce its greenhouse emissions. Yet energy consumption and carbon output in Britain—as in the rest of the world—had continued to rise. Why?
