Different types of institutions are involved in social finance. This paper studies the taxonomy and tradeoffs of those institutions. Our contribution is twofold. First, we map out and classify the full continuum of conceivable social finance institutions (SFIs), ranging from foundations offering pure grants to social banks supplying soft loans. The in-between category includes under-researched “quasi-foundations” granting loans requiring partial repayment. Second, we develop a model under which SFIs face information asymmetries and trade off social screening against social contributions, under a budget constraint depending on their funders’ generosity. We characterize SFIs’ optimal strategies and discuss whether they involve social screening of loan/grant applicants. The model establishes that quasi-foundations can be efficient vehicles for social finance, especially when social screening costs are relatively low. It also shows that social screening is indispensable in equilibrium when initiators of socially oriented projects can self-select themselves as applicants to SFIs.

Abstract: Social networks are expected to matter for invention in cities, but empirical evidence is still puzzling. In this paper, we provide new results on urban patenting covering more than twenty years of European patents invented by nearly one hundred thousand inventors located in France. Elaborating on the recent economic literatures on peer effects and on games in social networks, we assume that the productivity of an inventor’s efforts is positively affected by the efforts of his or her partners and negatively by the number of these partners’ connections. In this framework, inventors’ equilibrium outcomes are proportional to the square of their network centrality, which encompasses, as special cases, several well-known forms of centrality (Degree, Katz-Bonacich, Page-Rank). Our empirical results show that urban inventors benefit from their collaboration network. Their production increases when they collaborate with more central agents and when they have more collaborations. Our estimations suggest that inventors’ productivity grows sublinearly with the efforts of direct partners, and that they incur no negative externality from them having many partners. Overall, we estimate that a one standard deviation increase in local inventors’ centrality raises future urban patenting by 13%. We also find that geographically close relations are up to two third more beneficial to inventors than distant ones.

Abstract: Existing work provides contrasted arguments and evidence regarding the effects of a corporate scandal on the rivals of an implicated firm: while competitors may suffer from a negative contamination effect, they may also benefit from a positive substitution effect. Building and extending prior works, we develop a model to predict how contamination and substitution interact and jointly affect firm value during the course of a corporate scandal. We test and find support for our arguments using unique data, including 1.2m tweets, on the Dieselgate scandal that affected the global automobile industry in 2015.

Abstract: As algorithm-based judgement is often expected to outperform human judgement, algorithms are widely used to assist human with decision-making and also influence human’s decision-making. However, extant laboratory experiments find mixed evidences that humans may or may not appreciate algorithm-based judgement. While field evidence is scant, we leverage a unique dataset provided by a leading online peer-to-peer lending marketplace in China, where historical algorithm-based investments are visibly distinguishable from human investments for each loan listing upon individual lenders’ manual investment. We therefore investigate how algorithm-based investment influences manual investment. We find that algorithm-based investments positively affects subsequent lenders’ manual investment amount. Specifically, it is the average amount of the observed algorithm-based investments that positively affects the manual investment amount but not the number of the algorithm-based investments. We show that the impact of the observed algorithm-based investment decreases with the lenders’ experiences of manual investment, which is in line with the notion of “algorithm appreciation”. We further explore the underlying mechanism by ruling out several alternative explanations.

Abstract: The Italian judicial system is notoriously slow, with an estimated backlog of 5 million cases. We use a sample of 903,660 court cases in Turin to study the role that various adjudication procedures play in judicial delay. We exploit plausibly exogenous variation in the procedures governing how judges rule on small claims and implement a quasi-experimental approach to estimate the causal effect of less restrictive procedures on judicial delay. For any claim valued below e1,100, judges do not need to provide formal legal justification for their decisions. Judges can rule based on “equità”, i.e., fairness, intuition or commonsense grounds. For cases valued above this threshold, judges do not have such flexibility. Our regression discontinuity estimates, which ex- ploit the variation in these adjudication procedures just above and just below this threshold, reveal that when judges are able to rule without providing legal justification, decisions are made nearly six months faster. We discuss the policy implications in the realm of small claims including methods to ease congestion in Italian courts and efforts to improve judicial performance more broadly.

Abstract: The use of expert committees is common in many settings. A key concern is the potential for conflict of interest, particularly for members of committees that oversee regulated firms. However, ties to industry may be correlated with relevant expertise. We examine the voting behavior of members of the Food & Drug Administration's Advisory Committees (ACs), which make recommendations on new drug applications and other regulatory questions. Our work exploits a novel dataset that includes detailed information on each AC member, including their academic degrees, age, areas of expertise, and scientific contributions. We construct a measure of financial ties to industry using information disclosed in scientific publications authored by AC members, as well as those reported directly to the FDA and by the industry under the Sunshine Act. Advisors with industry ties generally have higher observable quality: they publish more, receive more NIH grants, etc. We estimate a structural model of voting that allows us to recover each member's skill and bias associated with financial ties to a drug's sponsor or its competitors. Our preliminary results indicate that financial ties to industry are associated with both an increased probability of voting in favor of a drug as well as higher skill.

Abstract: This paper proposes a three-step estimation strategy for dynamic conditional correlation models. In the first step, conditional variances for individual and aggregate series are estimated by means of QML equation by equation. In the second step, conditional covariances are estimated by means of the polarization identity and consistent estimates of the conditional correlations are obtained by their usual normalization. In the third step, the two-step conditional covariance and correlation matrices are regularized by means of a new non-linear shrinkage procedure and used as starting value for the maximization of the joint likelihood of the model. This yields the final, third step smoothed estimate of the conditional covariance and correlation matrices. Due to its scant computational burden, the proposed strategy allows to estimate high dimensional conditional covariance and correlation matrices. An application to global minimum variance portfolio is also provided, confirming that SP-DCC is a simple and viable alternative to existing DCC models for any application of interest.

Abstract: Network analysis is devoted to the study of a set of relationships with the aim of understanding the structure generated by these relationships. In this presentation we shall present an application of graph theory and network analysis in the field of international relations, particularly the case of ratifications of multilateral treaties related to the environment (work done in collaboration with Pierre Mazzega, University of Toulouse and Ana Flavia Barros-Platiau, University of Brasília). Indeed we can first analyze the network of "immediate ratifications" where a treaty X will be in relation with another treaty Y if there is a country that has ratified Y just after X. We can also have a dual vision where the ratifications of multilateral environmental agreements induce a network of countries linked in pairs when one ratifies the same agreement right after the other. Further modeling may be presented either on other networks that can be analyzed or on the use of hypergraphs.

Abstract: The fraction of women in economics has grown significantly over the last forty years. Yet, differences in research output between men and women remain large and persistent. These output differences are reflected in large network differences across the genders. Women have fewer collaborators, collaborate more often with the same coauthors, and a higher fraction of their coauthors are also coauthors of each other. Moreover, women coauthor a large share of their work and do so with more senior coauthors. Standard models of homophily and discrimination cannot account for these differences. We discuss how differences in risk aversion between men and women can explain them.

Abstract: Differences in regulated pharmaceutical prices within the European Economic Area can be exploited by pharmacy retailers using parallel imports. Such provision decisions affect the sharing of profits in markets for prescription drugs, including the profitability of innovating pharmaceutical companies before patent expiry, when parallel trade is the unique source of upstream competition. We develop a structural model of demand and supply where retailers can choose the set of goods to sell to consumers, thus foreclosing the access to some drugs, in response to differences in profitability across products. On the supply side, retailers bargain over wholesale prices with the manufacturer and parallel traders. With detailed transaction data, we identify a demand model with unobserved choice sets using supply side conditions for optimal assortment decisions of pharmacies. Estimating our model, we find that retailer incentives play a significant role in fostering parallel trade penetration. Our counterfactual simulations show that the parallel imports of drugs have large implications for the distribution of industry profits. In particular, retailers gain at the expense of pharmaceutical companies, while parallel traders also gain but more modest profits. Finally, a policy preventing pharmacies in foreclosing the manufacturer’s product is shown to partially shift profits from pharmacists to both parallel traders and the manufacturer, and a reduction in the regulated retail price favors the manufacturer even more.

Alors que la fonction publique emploie très largement des femmes, il y a relativement peu d’analyses sur les inégalités de rémunérations entre les hommes et les femmes dans ce secteur. Ce point aveugle est en partie lié à l’idée que les règles institutionnelles de recrutement et de fixation des rémunérations dans la fonction publique ajoutées au rôle protecteur des syndicats laissent moins de place à des inégalités selon le sexe. Toutefois un "plafond de verre" est également observé dans la fonction publique en France. Dans cette présentation, nous appliquerons une méthode proposée par Gobillon et al. (2015) pour estimer cette différence d'accès aux rangs les plus élevés. Dans un deuxième temps, nous montrerons que de ce point de vue, la fonction publique est très proche des pratiques du secteur privé.

Legal network analysis : Sources of Law form a large and growing network. Legislation is full of internal and external references, case law cites other case law and refers to legislation, legal doctrine and commentaries cite both case law and legislation and possibly other commentaries. This reserarch is aimed at trying to exploit this network structure to help (legal) practitioners and legal scholars. We address questions like: Can we use network features to determine authority of cases? Can we use it to assess the impact of planned legislative changes? Can we exploit the network structure to suggests useful sources of law to a practioner given a particular item, in focus? Can legal scholars use netweork analysis techniques to discover breaches in lines of thinking of courts?
Professor Winkels will give us a lecture on computational legal network analysis and disucss some applications in social sciences. Anyone interested in inter-disciplianary research on social sciences, legal studies and computer science should not miss it.

In this paper, we aim to bring the debate on the global productivity slowdown – which has largely been conducted from a macroeconomic perspective – to a more micro-level. We show that a particularly striking feature of the productivity slowdown is not so much a lower productivity growth at the global frontier, but rather rising labour productivity at the global frontier coupled with an increasing labour productivity divergence between the global frontier and laggard (non-frontier) firms. This productivity divergence remains after controlling for differences in capital deepening and mark-up behaviour, suggesting that divergence in measured multi-factor productivity (MFP) may in fact reflect technological divergence in a broad sense. This divergence could plausibly reflect the potential for structural changes in the global economy – namely digitalisation, globalisation and the rising importance of tacit knowledge – to fuel rapid productivity gains at the global frontier. Yet, aggregate MFP performance was significantly weaker in industries where MFP divergence was more pronounced, suggesting that the divergence observed is not solely driven by frontier firms pushing the boundary outward. We contend that increasing MFP divergence – and the global productivity slowdown more generally – could reflect a slowdown in the diffusion process. This could be a reflection of increasing costs for laggard firms of moving from an economy based on production to one based on ideas. But it could also be symptomatic of rising entry barriers and a decline in the contestability of markets. We find the rise in MFP divergence to be much more extreme in sectors where pro-competitive product market reforms were least extensive, suggesting that policy weaknesses may be stifling diffusion in OECD economies.
We quantify how access to frontier knowledge affects the creation of ideas. We show that citing frontier knowledge is correlated with producing high-quality papers. Because this correlation may be driven by unobserved factors, we identify the causal effect of frontier knowledge by analyzing a sudden collapse of international scientific cooperation. We show that World War I and the subsequent boycott against Central scientists severely reduced the dissemination of international knowledge, including knowledge at the scientific frontier. We then estimate how the reduction of international knowledge flows affected the productivity of scientists. Specifically, we compare productivity changes for scientists who relied on frontier knowledge from abroad, to changes for scientists who relied on frontier knowledge from home. After 1914, scientists who relied on frontier knowledge from abroad published fewer papers in top science journals and produced less Nobel Prize-nominated research. Our results indicates that access to the very best research, the top 1%, is essential for scientific progress.

This project is designed to develop a comprehensive database on the French stock markets since 1796, and to be extended to other kinds of data and to other European countries. In combination with other research infrastructures such as the SCOB database of the Antwerp University, it would meet the need for a benchmark infrastructure, first in France and then in Europe, to develop high-quality research by both scholars and the financial services.
Big data, smart data, data science... sont autant de termes qui ont diffusé auprès du public et des différents domaines scientfiques en quelques années. Les domaines de la santé et la recherche biomédicale en particulier s'y sont intéressé à partir de 2008, et le nombre de publications portant sur le "big data" en santé augmente exponentiellement depuis 2012. Néanmoins, nous sommes encore essentiellement au temps des promesses qui restent à concrétiser et à évaluer. En France, en particulier, il existe encore assez peu d'initiatives concrètes relevant d'une data science en santé. Parmi ces initiatives, la plupart sont actuellement portées par le milieu hospitalier, que ce soit en Ile de France (APHP) ou dans le Grand Ouest (CHRU de Brest, Rennes). Nous présentons ici le contexte du big data en santé, ainsi que deux projets actuellement en cours de déploiement en milieu hospitalier. Le projet d'entrepôt de données de santé soutenu par l'APHP et recouvrant les données de tous les établissements de l'APHP sera également présenté. D'autres projets en perspective à court et moyen termes seront esquissés.
