Answer the question at the end by quoting:

Irving Fisher (February 27, 1867 - April 29, 1947) was an American economist, statistician, inventor, and Progressive social campaigner. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the Post-Keynesian school. Joseph Schumpeter described him as "the greatest economist the United States has ever produced", an assessment later repeated by James Tobin and Milton Friedman. Fisher made important contributions to utility theory and general equilibrium.
Fisher is probably best remembered today in neoclassical economics for his theory of capital, investment, and interest rates, first exposited in his The Nature of Capital and Income (1906) and elaborated on in The Rate of Interest (1907). His 1930 treatise, The Theory of Interest, summed up a lifetime's research into capital, capital budgeting, credit markets, and the factors (including inflation) that determine interest rates. Fisher saw that subjective economic value is not only a function of the amount of goods and services owned or exchanged, but also of the moment in time when they are purchased with money. A good available now has a different value than the same good available at a later date; value has a time as well as a quantity dimension. The relative price of goods available at a future date, in terms of goods sacrificed now, is measured by the interest rate. Fisher made free use of the standard diagrams used to teach undergraduate economics, but labeled the axes "consumption now" and "consumption next period" (instead of the usual schematic alternatives of "apples" and "oranges"). The resulting theory, one of considerable power and insight, was presented in detail in The Theory of Interest (for a concise exposition, see here.) This model, later generalized to the case of K goods and N periods (including the case of infinitely many periods) has become a standard theory of capital and interest, and is described in Gravelle and Rees, and Aliprantis, Brown, and Burkinshaw. This theoretical advance is explained in Hirshleifer.

Some context: David William Donald Cameron (; born 9 October 1966) is a British politician who was Prime Minister of the United Kingdom from 2010 to 2016 and Leader of the Conservative Party from 2005 to 2016. He was Member of Parliament (MP) for Witney from 2001 to 2016. Cameron identifies as a One-Nation Conservative, and has been associated with both economically liberal and socially liberal policies. Born in London to wealthy upper middle-class parents, Cameron was educated at Heatherdown School, Eton College, and Brasenose College, Oxford.
The Conservatives' unexpected success in the 1992 election led Cameron to hit back at older party members who had criticised him and his colleagues, saying "whatever people say about us, we got the campaign right," and that they had listened to their campaign workers on the ground rather than the newspapers. He revealed he had led other members of the team across Smith Square to jeer at Transport House, the former Labour headquarters. Cameron was rewarded with a promotion to Special Adviser to the Chancellor of the Exchequer, Norman Lamont. Cameron was working for Lamont at the time of Black Wednesday, when pressure from currency speculators forced the pound sterling out of the European Exchange Rate Mechanism. At the 1992 Conservative Party conference, Cameron had difficulty trying to arrange to brief the speakers in the economic debate, having to resort to putting messages on the internal television system imploring the mover of the motion, Patricia Morris, to contact him. Later that month Cameron joined a delegation of Special Advisers who visited Germany to build better relations with the Christian Democratic Union; he was reported to be "still smarting" over the Bundesbank's contribution to the economic crisis. Lamont fell out with John Major after Black Wednesday and became highly unpopular with the public. Taxes needed to be raised in the 1993 Budget, and Cameron fed the options Lamont was considering through to Conservative Campaign Headquarters for their political acceptability to be assessed. By May 1993, the Conservatives' average poll rating dropped below 30%, where they would remain until the 1997 general election. Major and Lamont's personal ratings also declined dramatically. However, Lamont's unpopularity did not necessarily affect Cameron: he was considered as a potential "kamikaze" candidate for the Newbury by-election, which includes the area where he grew up. However, Cameron decided not to stand. During the by-election, Lamont gave the response "Je ne regrette rien" to a question about whether he most regretted claiming to see "the green shoots of recovery" or admitting to "singing in his bath" with happiness at leaving the European Exchange Rate Mechanism. Cameron was identified by one journalist as having inspired this gaffe; it was speculated that the heavy Conservative defeat in Newbury may have cost Cameron his chance of becoming Chancellor himself, even though as he was not a Member of Parliament he could not have been. Lamont was sacked at the end of May 1993, and decided not to write the usual letter of resignation; Cameron was given the responsibility to issue to the press a statement of self-justification.
Did Cameron and Lamont get along?

IN: Megan Denise Fox (born May 16, 1986) is an American actress and model. She began her acting career in 2001, with several minor television and film roles, and played a regular role on the Hope & Faith television sitcom. In 2004, she made her film debut with a role in the teen comedy Confessions of a Teenage Drama Queen. In 2007, she co-starred as Mikaela Banes, the love interest of Shia LaBeouf's character, in the blockbuster action film Transformers, which became her breakout role.

Fox began dating actor Brian Austin Green in 2004, after meeting on the set of Hope & Faith; she was 18 years old, while he was 30. They became engaged in November 2006. In February 2009, they had ended their engagement. Later that year, Fox was targeted by a group of fashion-motivated criminals known as "The Bling Ring", who robbed Green's home for access to Fox's possessions. Fox and Green were reported to have become engaged again on June 1, 2010, but Fox stated that she and Green had been continuously engaged since 2006. Fox and Green married on June 24, 2010 in a private ceremony at the Four Seasons Resort on Maui. Fox filed for divorce on August 21, 2015, a few days after she and Green announced their separation. By early 2016, the pairing were back together and expecting a third child. Together, they have three sons: Noah Shannon Green (born September 27, 2012), Bodhi Ransom Green (born February 12, 2014) and another born in 2016. Fox has a form of brachydactyly called clubbed thumb, and has discussed her obsessive-compulsive disorder (OCD), insecurities, self-harming, and has acknowledged that she has low self-esteem. In 2013, she said that her Christian faith is still very important to her and she believes it keeps her grounded. With regard to relationships and her sexuality, Fox said that she has a general distrust and dislike of men, and that the perception of her as a "wild and crazy sexpot" is false because she is asocial and has only been sexually intimate with her "childhood sweetheart" and Brian Austin Green; she stated that she would rather stay at home instead of going out, and emphasized that she cannot have sex with someone she does not love. She is bisexual, and said she believes that "all humans are born with the ability to be attracted to both sexes". "I have no question in my mind about being bisexual," Fox stated. "But I'm also a hypocrite: I would never date a girl who was bisexual, because that means they also sleep with men, and men are so dirty that I'd never want to sleep with a girl who had slept with a man."

Has she had any health problems?
