    This paper offers a theoretical framework to understand the coevolution of social interactions and long-term economic growth. It begins by considering that most traditional societies did not have educational markets. Thus, access to the required knowledge for transiting to a modern economy had to be transmitted through social interactions, in particular, through the interaction between heterogeneous groups of people–i.e. distant interactions. Once immersed in a modern economy, the productive system should have increased the demand for knowledge, promoting more distant interactions. Simultaneously, the emergence of distant interactions should have affected the connectivity of society, reducing its heterogeneity, making cheaper posterior interactions but reducing their profitability. Moreover, social interactions competed and benefited from other non-market activities, child rearing specifically. The model arrives at four basic predictions. First, modern economic growth brings a more cohesive society. Second, modern economic growth brings long-term reductions in fertility with potential short-term increases. Third, initial barriers to social interactions could explain the timing of modern economic growth arrival. Fourth, the timing of modern economic growth arrival could explain current output levels. I exploit different data sources to offer evidence in support of these predictions.

    This paper explores the relationship between social networks and entrepreneurship by constructing a dynamic social network from archival records. The network corresponds to the elite of a society in transition to modernity, characterized by difficult geographical conditions, market failures, and weak state capacity, as in late 19th- and early 20th-century Antioquia (Colombia). With these data, I estimate how the decision to found industrial firms was affected by the position of individuals in the social network. I find that individuals more important bridging the network (i.e. with higher betweenness centrality) were more involved in industrial entrepreneurship. However, I do not find individuals with a denser network to be more involved in this type of activity. The rationale of these results is that industrial entrepreneurship was a highly-complex activity that required a wide variety of complementary resources. Networks operated as substitutes of markets in the acquisition of these resources. Thus, individuals with network positions that favored the combination of a broad set of resources had a comparative advantage in industrial entrepreneurship. I run several tests to prove this rationale.

    This paper proposes a network formation model for explaining the stability of tribal societies. The model is supported by the idea that every two members of a tribe should have benefited from being connected to each other in order for the whole tribe to be stable. It also considers the constraints that the ecosystem brought to social interaction in pre-modern contexts. The model has three predictions. First, both homogeneous and heterogeneous tribes could have been stable regardless of technological development. Second, the social complexity of tribes was a function of technological development (having access to agriculture should have enabled the emergence of larger and more complex societies), interaction costs (if they were too low or too high, no complex society should have emerged), and environmental conditions (poor ecosystems should not have allowed the formation of complex societies). Finally, the model predicts that collapses of agricultural societies could not come from environmental pressures, but from high interaction costs. The predictions are consistent with some of the most relevant human history patterns.

  • My Library

    I enjoy collecting books. My library currently holds more than 1,400 volumes, with editions ranging from 1700 to the present. It specializes in the history of economic thought, Middle Eastern studies, Latin American studies, and East-Asian literature. Here some of my treasures:

  • My Library

    A first edition of Le Traité d'Économie Pure by Maurice Allais (1943)

    Several things make this volume a treasure:

    • It seems to be the only copy left in the world. It is a mimeographic edition, quite delicate and in perfect conditions. It was published during World War II, when the printing press was severely restricted, in particular, the mimeographic methods (this were the methods used by rebels).
    • It was the first work written by Maurice Allais and it can be considered one of the three pillars of modern economic theory.
    • It was the property of Kenneth Arrow (maybe the greatest social scientist of the second half of the twentieth century).
    • Allais was ahead of his time. Paul Samuelson (Nobel Prize in Economics in 1970) always thought that Allais deserved the Nobel Prize much earlier. When Allais received the Award in 1980, Samuelson said: "Had Allais earliest writings been in English, a generation of economic theory would have taken a different course"

    A first edition of Expected utility hypotheses and the Allais Paradox by Maurice Allais and Ole Hagen (1979)

    It was a gift from M. Allais to Jan Tinbergen. In the book dedication, Allais declares his admiration to Tinbergen, symbolizing a period in which the different branches of economics had a stronger connection.

     

    Tinbergen was awarded the first Nobel Prize in Economics ten years before this dedication. He is considered one of the founding fathers of econometrics and was tremendously influential in Europe—in macroeconomics, mostly. Meanwhile, Allais—who will be awarded the Nobel Prize about ten years after this dedication—was a theoretician, also very influential in Europe, but mostly in microeconomics.

    The complete works of Yasunari Kawabata (1899–1972)

    Kawabata was the first Japanese author to win the Nobel Prize in Literature (1968). His novels and short stories are characterized by a spare, lyrical, subtly-shaded prose. Kawabata can be considered the father of a tradition that survives nowadays with authors such as Kenzaburo Oe and Yoko Ogawa.

     

    My collection of Kawabata's works include a first English edition of The Lake (1974) and the compiled correspondence between Kawabata and Yukio Mishima.

    A first edition of Ricardo's Economics by Michio Morishima (1989).

    It was a gift from Morishima to Kenneth Arrow.
    In my opinion, it is an emblem of the end of an era: the end of general-theory research in mainstream economics. Kenneth Arrow was the most influential economist of his generation and a symbol of the Walrasian general theory heritage. Morishima was a very important dude too (he was a professor at LSE, President of the Econometric Society...). “Ricardo's Economics”, together with "Marx's Economics" and "Walras' Economics", completed a sequence of works in which Morishima reinterpreted the main general-theory traditions.

    A first edition of Almanaque La Ilustración (1880)

    This was Wikipedia before Wikipedia.

     

    Before the invention of the radio, it was quite difficult to know what was happening outside of one's village. This type of publications was the usual way to inform people on international reality. It had stories about geography, politics, culture, etc. It was beautifully illustrated by pieces based on travelers' narratives. An ideal example of how social sciences were deeply tied to literature and a recent past.
