IN: Roberto Mangabeira Unger (; born 24 March 1947) is a philosopher and politician. He has developed his views and positions across many fields, including social, political, and economic theory. In legal theory, he is best known by his work in the 1970s and 80s while at Harvard Law School as part of the Critical Legal Studies movement, which is held to have helped disrupt the methodological consensus in American law schools. His political activity helped the transition to democracy in Brazil in the aftermath of the military regime, and culminated with his appointment as Brazil's Minister of Strategic Affairs in 2007 and again in 2015.

Unger's critique of economics begins with the identification of a key moment in economic history, when the analysis of production and exchange turned away from social theory and engaged in a quest for scientific objectivity. In Unger's analysis, classical economics focused on the causal relations among social activities, which were connected with the production and distribution of wealth. Classical economists asked questions about the true basis of value, activities that contributed to national wealth, systems of rights, or about the forms of government under which people grow rich. In the late-nineteenth century, in response to attacks from socialist ideas and debates about how society works, and as a means to escape the conundrums of value theory and to answer how values could become prices, marginalist economics arose. This movement in economics disengaged economics from prescriptive and normative commitments to withdraw the study of economies from debates about how society worked and what kind of society we wanted to live in. For Unger, this moment in the history of economics robbed it of any analytical or practical value.  Unger's critique of Marginalism begins with Walras' equilibrium theory, which attempted to achieve a certainty of economic analysis by putting aside normative controversies of social organization. Unger finds three weaknesses that crippled the theory: foremost, the theory claimed that equilibrium would be spontaneously generated in a market economy. In reality, a self-adjusting equilibrium fails to occur. Second, the theory puts forth a determinate image of the market. Historically, however, the market has been shown to be indeterminate with different market arrangements. Third, the polemical use of efficiency fails to account for the differences of distribution among individuals, classes, and generations.  The consequences of the marginalist movement were profound for the study of economics, Unger says. The most immediate problem is that under this generalizing tendency of economics, there is no means by which to incorporate empirical evidence and thus to re-imagine the world and develop new theories and new directions. In this way, the discipline is always self-referential and theoretical. Furthermore, the lack of a normative view of the world curtails the ability to propose anything more than a policy prescription, which by definition always assumes a given context. The discipline can only rationalize the world and support a status quo. Lastly, Unger finds that this turn in economics ended up universalizing debates in macroeconomics and leaving the discipline without any historical perspective. A consequence, for example, was that Keynes' solution to a particular historical crisis was turned into a general theory when it should only be understood as a response to a particular situation.
QUESTION: WHICH PUBLISHED IN 1987?
IN: Andrew Carnegie ( kar-NAY-gee, but commonly  KAR-n@-ghee or  kar-NEG-ee; November 25, 1835 - August 11, 1919) was a Scottish-American industrialist, business magnate, and philanthropist. Carnegie led the expansion of the American steel industry in the late 19th century and is often identified as one of the richest people (and richest Americans). He became a leading philanthropist in the United States and in the British Empire. During the last 18 years of his life, he gave away about $350 million to charities, foundations, and universities--almost 90 percent of his fortune.

Carnegie did not want to marry during his mother's lifetime, instead choosing to take care of her in her illness towards the end of her life. After she died in 1886, the 51-year-old Carnegie married Louise Whitfield, who was 21 years his junior. In 1897, the couple had their only child, a daughter, whom they named after Carnegie's mother, Margaret.  Carnegie made his fortune in the steel industry, controlling the most extensive integrated iron and steel operations ever owned by an individual in the United States. One of his two great innovations was in the cheap and efficient mass production of steel by adopting and adapting the Bessemer process, which allowed the high carbon content of pig iron to be burnt away in a controlled and rapid way during steel production. Steel prices dropped as a result, and Bessemer steel was rapidly adopted for rails; however, it was not suitable for buildings and bridges.  The second was in his vertical integration of all suppliers of raw materials. In the late 1880s, Carnegie Steel was the largest manufacturer of pig iron, steel rails, and coke in the world, with a capacity to produce approximately 2,000 tons of pig metal per day. In 1883, Carnegie bought the rival Homestead Steel Works, which included an extensive plant served by tributary coal and iron fields, a 425-mile (684 km) long railway, and a line of lake steamships. Carnegie combined his assets and those of his associates in 1892 with the launching of the Carnegie Steel Company.  By 1889, the U.S. output of steel exceeded that of the UK, and Carnegie owned a large part of it. Carnegie's empire grew to include the J. Edgar Thomson Steel Works in Braddock, (named for John Edgar Thomson, Carnegie's former boss and president of the Pennsylvania Railroad), Pittsburgh Bessemer Steel Works, the Lucy Furnaces, the Union Iron Mills, the Union Mill (Wilson, Walker & County), the Keystone Bridge Works, the Hartman Steel Works, the Frick Coke Company, and the Scotia ore mines. Carnegie, through Keystone, supplied the steel for and owned shares in the landmark Eads Bridge project across the Mississippi River at St. Louis, Missouri (completed 1874). This project was an important proof-of-concept for steel technology, which marked the opening of a new steel market.
