Human Development, Social Interactions, and Identity Formation

40 pagesThis paper presents a general theory of child development that incorporates interactive learning and identity formation in social interactions with caregivers. The model sheds light on many puzzling aspects of child development. Child learning responds nonmonotonically to caregivers' attention and approval in social interactions. I highlight key parental characteristics associated with child learning, and identity formation. The theory also explains why media devices widen human inequality. Lessons are finally drawn for the design of policies that alleviate human inequality

The Political Economy of Foreign Aid and Growth: Theory and Evidence

In this paper, we demonstrate that even when foreign aid is used to fund patronage, it may still have a positive - and significant - effect on economic growth in developing countries. First, we present a theory that formalizes the effect of aid on economic growth and patronage. Next, we provide evidence from Pakistan consistent with the predictions of the model that foreign aid increases economic growth, despite being used for patronage. The identification strategy we propose allows us to provide causal evidence for the predictions of the model

A Theory of Cultural Revivals

Why do some societies have political institutions that support productively inefficient outcomes? And why does the political power of elites vested in these outcomes often grow over time, even when they are unable to block more efficient modes of production? We propose an explanation centered on the interplay between political and cultural change. We build a model in which cultural values are transmitted inter-generationally. The cultural composition of society, in turn, determines public good provision as well as the future political power of elites from different cultural groups. We characterize the equilibrium of the model and provide sufficient conditions for the emergence of cultural revivals. These are characterized as movements in which both the cultural composition of society as well as the political power of elites who are vested in productively inefficient outcomes grow over time. We reveal the usefulness of our framework by applying it to two case studies: the Jim Crow South and Turkey\u27s Gülen Movement

Culture, Institutions & the \u3cem\u3eLong Divergence\u3c/em\u3e

During the medieval and early modern periods the Middle East lost its economic advantage relative to the West. Recent explanations of this historical phenomenon— called the Long Divergence—focus on these regions’ distinct political economy choices regarding religious legitimacy and limited governance. We study these features in a political economy model of the interactions between rulers, secular and clerical elites, and civil society. The model induces a joint evolution of culture and political institutions (delegation of power from rulers to elites) converging to one of two distinct stationary states: a religious and a secular regime. We then map qualitatively parameters and initial conditions characterizing the West and the Middle East (separation between state and religion, initial political power of clerical elites, and predominance of religious values in the population) into the implied model dynamics to show that they are consistent with the Long Divergence as well as with several key stylized political and economic facts highlighted in the historical narrative. Most notably, this mapping suggests non-monotonic political economy strategies in both regions, in terms of legitimacy and limited governance, which indeed characterize their history

Religious Rituals: Evidence from Ramadan

We estimate the impact of the Ramadan fasting ritual on criminal sentencing decisions for Pakistan and India from half a century of daily data. We use random case assignment and exogenous variation in fasting intensity within Ramadan due to the rotating Islamic calendar and the geographical latitude of the district courts to document large effects of Ramadan fasting on decision-making. Our sample comprises roughly a half million judicial cases and 10,000 judges from Pakistan and India. Ritual intensity increases acquittal rates of Muslim judges, lowers their appeals and reversal rates, and does not come at the cost of increased recidivism or heightened outgroup bias. Overall, our results highlight that the Ramadan fasting ritual followed by a billion Muslims worldwide induces more lenient decisions that appear to be of higher quality

Social Roles

In this paper, I introduce a workable dynamic utility model on the interplay between economic actions and social roles. I model both how economic actions are embedded in social roles, and how social roles reciprocally feed back into preferences and affect economic outcomes. I also consider a set of policy interventions aimed at breaking social roles when they deteriorate economic outcomes

The Priced Survey Methodology: Theory

In this paper, I introduce a novel methodology to conduct surveys. The priced survey methodology (PSM). Like standard surveys, priced surveys are easy to implement, and measure social preferences on numerical scales. The PSM's design draws inspiration from consumption choice experiments, as respondents fill out the same survey several times under different choice sets. I extend Afriat's theorem and show that the Generalized Axiom of Revealed Preferences is necessary and sufficient for the existence of a concave, continuous, and single-peaked utility function rationalizing answers to the PSM. I apply the PSM to a sample of online participants and show that most respondents are rational when answering the PSM. I estimate respondents' single-peaked utility functions and draw several implications on their social preferences

Essais en économie politique et sur l'évolution des normes culturelles

The first chapter of this dissertation presents a theory of child development and parental rearingpractices. In the model, a benevolent parent seeks to transmit cultural norms to her child, whoacquires cognitive skills and develops a capital of appreciation for adopting behaviors that accordwith these norms. Our cultural perspective on the issue of cognitive development provides aninterpretation grid for various results established in the empirical literature. It also permits to identifythe parental characteristics that are conducive to various parenting styles, to child neglect and tochild maltreatment.The second chapter provides a theory of religious prohibition against usury and innovation and itsconsequences on economic activities and occupations. As an economic prohibition from themajority religion is sustained by a threat of social exclusion from that cultural group, it has lesseffects on religious minorities. It then creates an occupational pattern where only the religiousminorities choose activities that transgress the prohibition. By creating resentment against thereligious minorities, this occupational pattern strengthens the diffusion of the majority religion in thepopulation. An economic prohibition is then instigated by the clerics in the majority religion,because it allows them to consolidate their norms and to increase the scope of their control overpopular masses. This work also demonstrates that an economic prohibition lasts longer whenreligious clerics can legitimize secular rulers and when the competition on the religious market isweaker.In the last chapter, we present a microfounded theory of multi-candidate political competition takingan "industrial organization" perspective of politics. The analytical framework is shown to be exibleenough to address several applications on the topics of special interest politics, coalition formationin the legislature in proportional elections, and redistribution under alternative electoral rulesCette dissertation est composée de trois articles traitant de sujets divers. Le premier développe une théorie sur la transmission de normes culturelles. Le second article traite de l'évolution des doctrines religieuses dans une économie productive. Enfin, le dernier article de cette dissertation est un travail joint avec Thierry Verdier. L'article propose une nouvelle approche des élections impliquant un nombre arbitraire de candidats. Cette problématique de recherche est importante non seulement quant à sa complexité théorique, mais aussi parce qu'elle permet d'étudier relativement simplement la structure des marchés politiques.Le premier article présente une théorie sur le développement de l'enfant et les pratiques parentales. Dans le modèle, un parent cherche à transmettre des normes comportementales à son enfant en lui envoyant des signaux, que l'enfant observe de manière imparfaite. L'enfant peut cependant augmenter la qualité des signaux qu'il reçoit en investissant dans l'acquisition de compétences cognitives.Nous établissons que les styles parentaux autoritaires ou permissifs décroissent l'accumulation de compétences cognitives. De plus, puisque les interactions entre parents et enfants visent à transmettre des normes comportementales, l'enfant développe un capital d'appréciation pour le développement de compétences cognitives.Notre perspective culturelle sur la question du développement cognitif fournit une grille d'interprétation utile pour divers résultats établis dans la littérature empirique sur le développement de l'enfant.Le second article propose une théorie de la prohibition religieuse contre l'usure et l'innovation et ses conséquences sur les activités et les occupations économiques.Comme une interdiction économique provenant de la religion majoritaire est soutenue par un risque d'exclusion sociale de ce groupe culturel, elle a moins d'effets sur les minorités religieuses. Cela implique que seules les minorités religieuses choisissent des activités qui vont à l'encontre de la prohibition à l'équilibre.Dans le dernier article, nous présentons une théorie micro-fondée de la concurrence politique à plusieurs candidats prenant une perspective ``d'organisation industrielle" de la politique. Nous présentons d'abord un modèle de vote aléatoire qui utilise des distributions introduites par le mathématicien français Maurice Fréchet et qui portent son nom. Ces distributions permettent d'exprimer les parts de vote des différents candidats comme des ``contest functions'', ce qui permet d'établir un théorème d'existence et d'unicité d'un équilibre des stratégies politiques dans des élections impliquant un nombre arbitraire de candidats.Le cadre analytique s'avère suffisamment souple pour traiter plusieurs applications sur des thèmes liés à la structure endogène des marchés politiques. Nous montrons en particulier que le degré d'information des électeurs sur les plateformes ainsi que les campagnes médiatiques impliquent un degré de fragmentation politique plus faible
