After secondary school, Sylos Labini enrolled in the Faculty of Law at the Sapienza University of Rome, graduating in July 1942 with a thesis on the economic consequences of innovations.^[1] In his research, he turned to study classical economists—in particular Adam Smith, David Ricardo, and Karl Marx—after becoming aware of the limited interest in innovations among contemporary economists. At the time, his mentor was Alberto Breglia (1900–1955), a professor of political economy at Sapienza University since 1942.

After graduating with a cum laude distinction in law in July 1942, Sylos Labini was appointed as a voluntary assistant. He was later appointed as the assistant professor of political economy at the Faculty of Economics of Sapienza University. Labini's relationship with Breglia left him with the concept of economy as a way to understand history. Breglia encouraged Labini to travel to the United States to complete his studies, and Sylos Labini was among the first young people after World War II to study abroad. Labini ventured overseas in the hope of deepening his economic knowledge and to better understand the peculiarities of the Italian economic status.

In 1948, Sylos Labini first went to Chicago, where he met Franco Modigliani, and then to Cambridge, Massachusetts, to study with Joseph Schumpeter at Harvard University.^[1] At Harvard, he met Gaetano Salvemini and John Kenneth Galbraith. He also studied for a time in Cambridge, where he was supervised by Dennis Robertson, and became friends with Piero Sraffa, Nicholas Kaldor, Joan Robinson.

Sylos Labini qualified as a lecturer in political economy in 1953, then taught at different universities. In 1955, he became an assistant professor of political economy at the Faculty of Economics of the University of Sassari. In February 1958, he was appointed professor of economic and financial policy at the Faculty of Law. The following year, he taught political economy at the Faculty of Economics of the University of Catania. Sylos Labini moved to the University of Bologna, before returning to Sapienza University in October 1962, where he taught principles of political economy at the Faculty of Statistical, Demographic, and Actuarial Sciences until his retirement in 1995. He was appointed emeritus professor in 1997.

Sylos Labini's main contribution came in 1956, with Oligopolio e Progresso tecnico (English edition, Oligopoly and Technical Progress, 1962).^[2] The book was published around the same time as Joe Bain's Barriers to New Competition (1956).^[3] The two works were grouped together in an article by Franco Modigliani (1958), which caused them to become accepted as part of mainstream theory on non-competitive market forms.

Sylos Labini attached great importance to the dynamic aspects of his analysis. For over sixty years, from his dissertation onwards, the theme of technical progress has been a constant presence in his work: like Smith, Labini considered it as the main element for economic development (Smith's Wealth of Nations), as a precondition, though not automatic, for civil development of society. Alongside this, the other central theme was that (Ricardian, but also present in Smith) of the distribution of income, and more generally of the living conditions of the various strata of society. This line of research was developed in Sindacati, inflazione e produttività (1972); English edition, Trade Unions, Inflation and Productivity, 1974.^[4] Wages and prices are not determined in fully competitive markets. These themes reappear in many subsequent contributions; an idea of the width and depth of Labini's analysis is provided by The Forces of Economic Growth and Decline (1984),^[5] which remains the major reference point for studying his economic thought.

Like Smith, Sylos Labini argues that economic development can foster civil development in society, while the latter is in turn a fundamental condition for sustainable economic development.

Between 1966 and 1967, Sylos Labini worked on developing an econometric model of the Italian economy. His model was the first systematic econometric research on the Italian economy, and was aimed to reconcile theoretical analysis with historical changes while being gradually modified with new variables. The econometric studies intertwined with the analysis of major Italian problems of economic policy. Between 1965 and 1975, Sylos Labini published a series of works on wages, productivity, and inflation, which incorporated the results of his econometric analysis.

According to Sylos Labini, an economist is necessarily influenced by personal judgment, which determines, at a minimum, the choice of problems studied and which may also skew the outcome of the analysis.

In his last book, Ahi serva Italia (2006), Sylos Labini spoke as a civic-minded economist to Italians who refuse to understand that respect for rules is an absolute requirement of a market economy. He argued that capitalism cannot function without a widespread moral sentiment that condemns the breach of rules.

On this subject, Sylos Labini referred to an excerpt from Gaetano Salvemini:

Almost all of those old teachers belonged to a school of thought which today is viewed disparagingly as positivistic, enlightened, intellectualist. Their culture, and ours, was narrow, dry, and down-to-earth, inept when it came to rising to the lofty skies of intuitionism and idealism. In those times of unelevated culture, we were clearly split into believers or non-believers, the pro- or anticlerical, conservatives or revolutionaries, monarchists or republicans, individualists or socialists. White was white and black was black. White was good and black was bad. With us or against us. When we poor little empirical sparrows ended up in the clutches of the idealist eagles and were devoured, white became half-black and black half-white, good half-bad and bad half-good, the scoundrel was half a gentleman and the gentleman was half a scoundrel. Today, in Italy, the clerics are half-communists, and the communists half-clerics. The same lamps that light the Communist celebrations serve in the pilgrimages of the Blessed Virgin. It is the Tower of Babel. As for myself, I have remained anchored, or if you prefer, aground there where my teachers had first led me: an odd boulder left behind on some plain by a receding glacier. (Salvemini, 1950, p. 87)^[6]
