Type of actors, objects of exchange, type of original transactions in the coverage of corruption

In the following analysis we deal with only specific corruption cases within our seven-country sample for content analysis (France, Hungary, Italy, Latvia, Romania, Slovakia, and the UK). Only 5,212 relevant articles dealt with such cases within the total sample (12,742). We focus here on providing a descriptive comparative analysis of the actors, types of transactions and country specifics. The second part of the analysis describes the actors involved in the corrupt transactions, while in the third section we deal with the object of exchange in corrupt transactions. The fourth section focuses on the type of transaction which is linked to the corruption. Finally, a summary of the results of our preliminary findings is provided.

Essays on the Dynamic Decisions of Homeowners and Retailers

Urban problems have several features that make them inherently dynamic. Large transaction costs all but guarantee that homeowners will do their best to consider how a neighborhood might change before buying a house. Similarly, stores face large sunk costs when opening, and want to be sure that their investment will pay off in the long run. In line with those concerns, different areas of Economics have made recent advances in modeling those questions within a dynamic framework. This dissertation contributes to those efforts.

Chapter 2 discusses how to model an agent’s location decision when the agent must learn about an exogenous amenity that may be changing over time. The model is applied to estimating the marginal willingness to pay to avoid crime, in which agents are learning about the crime rate in a neighborhood, and the crime rate can change in predictable (Markovian) ways.

Chapters 3 and 4 concentrate on location decision problems when there are externalities between decision makers. Chapter 3 focuses on the decision of business owners to open a store, when its demand is a function of other nearby stores, either through competition, or through spillovers on foot traffic. It uses a dynamic model in continuous time to model agents’ decisions. A particular challenge is isolating the contribution of spillovers from the contribution of other unobserved neighborhood attributes that could also lead to agglomeration. A key contribution of this chapter is showing how we can use information on storefront ownership to help separately identify spillovers.

Finally, chapter 4 focuses on a class of models in which families prefer to live

close to similar neighbors. This chapter provides the first simulation of such a model in which agents are forward looking, and shows that this leads to more segregation than it would have been observed with myopic agents, which is the standard in this literature. The chapter also discusses several extensions of the model that can be used to investigate relevant questions such as the arrival of a large contingent high skilled tech workers in San Francisco, the immigration of hispanic families to several southern American cities, large changes in local amenities, such as the construction of magnet schools or metro stations, and the flight of wealthy residents from cities in the Rust belt, such as Detroit.

On the Regulation of Small Actors: Three Experimental Essays about Policies based on Voluntary Compliance and Decentralized Monitoring

Monitoring and enforcement are perhaps the biggest challenges in the design and implementation of environmental policies in developing countries where the actions of many small informal actors cause significant impacts on the ecosystem services and where the transaction costs for the state to regulate them could be enormous. This dissertation studies the potential of innovative institutions based on decentralized coordination and enforcement to induce better environmental outcomes. Such policies have in common that the state plays the role of providing the incentives for organization but the process of compliance happens through decentralized agreements, trust building, signaling and monitoring. I draw from the literatures in collective action, common-pool resources, game-theory and non-point source pollution to develop the instruments proposed here. To test the different conditions in which such policies could be implemented I designed two field-experiments that I conducted with small-scale gold miners in the Colombian Pacific and with users and providers of ecosystem services in the states of Veracruz, Quintana Roo and Yucatan in Mexico. This dissertation is organized in three essays.

The first essay, “Collective Incentives for Cleaner Small-Scale Gold Mining on the Frontier: Experimental Tests of Compliance with Group Incentives given Limited State Monitoring”, examines whether collective incentives, i.e. incentives provided to a group conditional on collective compliance, could “outsource” the required local monitoring, i.e. induce group interactions that extend the reach of the state that can observe only aggregate consequences in the context of small-scale gold mining. I employed a framed field-lab experiment in which the miners make decisions regarding mining intensity. The state sets a collective target for an environmental outcome, verifies compliance and provides a group reward for compliance which is split equally among members. Since the target set by the state transforms the situation into a coordination game, outcomes depend on expectations of what others will do. I conducted this experiment with 640 participants in a mining region of the Colombian Pacific and I examine different levels of policy severity and their ordering. The findings of the experiment suggest that such instruments can induce compliance but this regulation involves tradeoffs. For most severe targets – with rewards just above costs – raise gains if successful but can collapse rapidly and completely. In terms of group interactions, better outcomes are found when severity initially is lower suggesting learning.

The second essay, “Collective Compliance can be Efficient and Inequitable: Impacts of Leaders among Small-Scale Gold Miners in Colombia”, explores the channels through which communication help groups to coordinate in presence of collective incentives and whether the reached solutions are equitable or not. Also in the context of small-scale gold mining in the Colombian Pacific, I test the effect of communication in compliance with a collective environmental target. The results suggest that communication, as expected, helps to solve coordination challenges but still some groups reach agreements involving unequal outcomes. By examining the agreements that took place in each group, I observe that the main coordination mechanism was the presence of leaders that help other group members to clarify the situation. Interestingly, leaders not only helped groups to reach efficiency but also played a key role in equity by defining how the costs of compliance would be distributed among group members.

The third essay, “Creating Local PES Institutions and Increasing Impacts of PES in Mexico: A real-Time Watershed-Level Framed Field Experiment on Coordination and Conditionality”, considers the creation of a local payments for ecosystem services (PES) mechanism as an assurance game that requires the coordination between two groups of participants: upstream and downstream. Based on this assurance interaction, I explore the effect of allowing peer-sanctions on upstream behavior in the functioning of the mechanism. This field-lab experiment was implemented in three real cases of the Mexican Fondos Concurrentes (matching funds) program in the states of Veracruz, Quintana Roo and Yucatan, where 240 real users and 240 real providers of hydrological services were recruited and interacted with each other in real time. The experimental results suggest that initial trust-game behaviors align with participants’ perceptions and predicts baseline giving in assurance game. For upstream providers, i.e. those who get sanctioned, the threat and the use of sanctions increase contributions. Downstream users contribute less when offered the option to sanction – as if that option signal an uncooperative upstream – then the contributions rise in line with the complementarity in payments of the assurance game.

Critique féministe matérialiste du droit civil québécois : le travail « domestique » et les violences sexuées, les « impensés » du droit du logement.

Cette recherche constitue un essai de théorie critique féministe matérialiste et radicale. Elle poursuit principalement un objectif de dénonciation de la structure actuelle du droit du logement. À partir d’un cadre conceptuel fondé sur le féminisme matérialiste et radical, elle souhaite faire ressortir le point de vue de la classe des femmes dans l’habitation. Le droit du logement est ici utilisé dans un sens large, puisqu’il se réfère à la fois au logement comme phénomène juridique, mais aussi sociologique. À l’intérieur de la discipline juridique, il renvoie à l’ensemble des législations actuellement en vigueur au Québec en ce qui concerne la vie à domicile. Notre étude se concentre sur deux modes d’occupation des lieux, à travers le droit de propriété et le système locatif. Le droit au logement fait l’objet d’une reconnaissance internationale dans les textes portant sur les droits humains. Il est reconnu comme le « droit à un logement suffisant ». Au Canada et au Québec, il ne fait pas l’objet d’une reconnaissance explicite, malgré les engagements pris sur la scène internationale. Un portrait statistique, appuyé sur le critère du sexe, permet de mettre en évidence qu’il existe des écarts entre les hommes et les femmes en ce qui concerne la mise en application du droit du logement. Les femmes accèdent plus difficilement à un logement; elles y effectuent la majorité du travail domestique, de service et de « care » et elles sont les principales victimes des violences commises à domicile. Dans le système d’habitation, l’expérience des femmes se comprend comme une appropriation à la fois privée et collective par la classe des hommes, telle que réfléchie par Colette Guillaumin, qui se concentre autour de la division sexuelle du travail et des violences sexuées. Le droit du logement, dans sa forme actuelle, repose sur l’appropriation de la force de travail des femmes et de leur corps. Ces deux critères permettent de construire une grille d’analyse féministe matérialiste et radicale pour analyser la structure du droit du logement, tel que conçu en droit civil. Cette analyse féministe permet également de situer le droit étatique comme une pratique patriarcale. Cette dernière contribue à assurer le maintien du système d’habitation, qui est assimilable à un système hégémonique, au sens développé par Gramsci. Cette étude réfléchit sur le droit du logement dans le climat politique néolibéral. Le néolibéralisme est développé comme une idéologie qui impose une rationalité marchande à l’ensemble des politiques étatiques. À partir d’une méthode décrite comme métathéorique externe radicalement réflexive, puisqu’elle propose l’importation d’outils conceptuels étrangers à la discipline du droit moderne, nous réfléchissons de manière radicale la construction du droit civil et des institutions qui encadrent le droit du logement. La collecte des données s’effectue à partir de la recherche documentaire. Quatre institutions du droit civil seront examinées dans le détail, soit le sujet du droit, la dichotomie privé/public, la médiation du droit du logement par les biens immeubles, à travers le rapport contractuel et le droit de propriété, et finalement les notaires. L’analyse féministe du sujet du droit insiste sur un paradoxe. D’une part, l’universalité présumée de ce sujet, laquelle permet de poser l’égalité et la liberté pour toutes les personnes juridiques. Or, plutôt que d’être neutre sexuellement comme le prétend le droit positif, nous démontrons comment ce sujet est constamment un membre de la classe des hommes. D’autre part, nous analysons comment le droit reconnaît le sexe de ses sujets, mais surtout comment cette sexualité est construite sur l’idéologie naturaliste. Ce modèle de sujet masculin est fondamental dans la construction du droit du logement. L’étude féministe de la dichotomie privé/public en fait ressortir le caractère situé. En effet, si par essence aucun domaine ou enjeu n’est en soit privé ou public, le processus de qualification, lui, est un acte de pouvoir. Nous verrons comment le droit civil crée des zones de droit privé, comprises comme des zones de non-droit pour les femmes. La qualification de privé dévalue également le travail accompli par cette classe de sexe. Le droit du logement est pourtant centré sur le rapport contractuel et sur le droit de propriété. Il importe alors d’examiner la nature du consentement donné par les femmes comme groupe social dans les contrats de vente et de location. Ces contrats ne prennent pas en compte l’expérience des femmes dans leur formation. Les catégories qui y sont attachées, telles que vendeur.e ou locataire, représentent le point de vue de la classe des hommes. Bien que la popularité de la copropriété auprès de la classe des femmes semble porteuse d’un vent de changement, nous analysons comment le discours dominant qui l’entoure instrumentalise certaines revendications féministes, tout en laissant dans l’ombre la question du travail domestique et des violences sexuées. Finalement, nous nous intéressons aux notaires en les repensant comme des intellectuel.les organiques, tels que conçu.es par Gramsci, pour la classe des hommes. Cette fonction d’intellectuel.les permet de mettre en lumière comment chaque transaction immobilière favorise la reproduction des intérêts patriarcaux, remettant ainsi en question la nature des devoirs de conseil et d’impartialité du notariat. À la lumière de cette analyse, le Code civil du Québec est qualifié dans une perspective féministe matérialiste et radicale pour devenir un système qui institutionnalise l’appropriation des femmes par l’entremise du droit du logement. Ce travail de recherche permet d’envisager certaines pistes de réflexion pour des rénovations potentielles des pratiques juridiques entourant le droit du logement, notamment la pratique notariale, tournées vers des objectifs féministes de justice sociale.

Cultural cooperation, institution building, and metropolitan governance in decentralizing Indonesia

The institutional turn in metropolitan governance has been influenced to a considerable degree by a rational choice approach, which views metropolitan governance as essentially created by local actors to reduce the transaction costs of inter-jurisdictional public-service provision. Another influential theoretical route follows a historical approach, which emphasizes the role of the state structure in producing formal institutions to enable governance at the regional level. Both approaches tend to be formalistic, simplistic and deterministic in nature, thus neglecting the dynamic interactions between the actors and their more informal, intangible, yet more basic, legitimate institutions, such as culture. This article examines the dynamic role of culture in metropolitan governance building in the context of decentralizing Indonesia. The analysis focuses on ‘best-practice’ experiences of metropolitan cooperation in greater Yogyakarta, where three neighbouring local governments known as Kartamantul have collaboratively performed cross-border infrastructure development to deal with the consequences of extended urbanization. We draw on sociological institutionalism to argue that building this metropolitan cooperation has its roots in the capacity of the actors to use and mobilize culture as a resource for collaborative action.

Default Invariance: Naïve Category of Law and Finance

Default invariance is the idea that default does not change at any scale of law and finance. Default is a conserved quantity in a universe where fundamental principles of law and finance operate. It exists at the micro-level as part of the fundamental structure of every financial transaction, and at the macro- level, as a fixed critical point within the relatively stable phases of the law and finance cycle. A key point is that default is equivalent to maximizing uncertainty at the micro-level and at the macro-level, is equivalent to the phase transition where unbearable fluctuations occur in all forms of risk transformation, including maturity, liquidity and credit. As such, default invariance is the glue that links the micro and macro structures of law and finance. In this essay, we apply naïve category theory (NCT), a type of mapping logic, to these types of phenomena. The purpose of using NCT is to introduce a rigorous (but simple) mathematical methodology to law and finance discourse and to show that these types of structural considerations are of prime practical importance and significance to law and finance practitioners. These mappings imply a number of novel areas of investigation. From the micro- structure, three macro-approximations are implied. These approximations form the core analytical framework which we will use to examine the phenomena and hypothesize rules governing law and finance. Our observations from these approximations are grouped into five findings. While the entirety of the five findings can be encapsulated by the three approximations, since the intended audience of this paper is the non-specialist in law, finance and category theory, for ease of access we will illustrate the use of the mappings with relatively common concepts drawn from law and finance, focusing especially on financial contracts, derivatives, Shadow Banking, credit rating agencies and credit crises.

Impact of the Financial Crisis on the Performance of European Acquisitions

This study looks at the impact of the recent financial crisis on the short-term performance of European acquisitions. We use institutional theory and transaction cost economic theory to study whether bidders derive lower or higher returns from acquisitions announced after 2008. We investigate shareholders’ stock price reaction to 2245 deals which occurred during 2004–12 across 22 European Union countries. Our results from both univariate and multivariate analysis show that the deals announced in the post-crisis period, corresponding to the period of economic recession, generate higher returns to shareholders as compared to acquisitions announced in the pre-crisis period. We also test the relevance of the Economic and Monetary Union (EMU), that is, the Eurozone, to this value accrual during the recessionary period. We observe that non-EMU transactions obtain significantly higher gains vis-à-vis EMU transactions in the post-crisis years. Overall, announcement returns of European acquisitions have been affected by the financial crisis and the global recession; and companies that target countries with different currency regimes are likely to generate better returns from their acquisitions.

Late-career international migration and reproductive work. A comparison between Peruvian and Ukrainian women in the Southern Europe

Research on the relationship between reproductive work and women´s life trajectories including the experience of labour migration has mainly focused on the case of relatively young mothers who leave behind, or later re-join, their children. While it is true that most women migrate at a younger age, there are a significant number of cases of men and women who move abroad for labour purposes at a more advanced stage, undertaking a late-career migration. This is still an under-estimated and under-researched sub-field that uncovers a varied range of issues, including the global organization of reproductive work and the employment of migrant women as domestic workers late in their lives. By pooling the findings of two qualitative studies, this article focuses on Peruvian and Ukrainian women who seek employment in Spain and Italy when they are well into their forties, or older. A commonality the two groups of women share is that, independently of their level of education and professional experience, more often than not they end up as domestic and care workers. The article initially discusses the reasons for late-career female migration, taking into consideration the structural and personal determinants that have affected Peruvian and Ukrainian women’s careers in their countries of origin and settlement. After this, the focus is set on the characteristics of domestic employment at later life, on the impact on their current lives, including the transnational family organization, and on future labour and retirement prospects. Apart from an evaluation of objective working and living conditions, we discuss women’s personal impressions of being domestic workers in the context of their occupational experiences and family commitments. In this regard, women report varying levels of personal and professional satisfaction, as well as different patterns of continuity-discontinuity in their work and family lives, and of optimism towards the future. Divergences could be, to some extent, explained by the effect of migrants´ transnational social practices and policies of states.

Perspectives on gender, migration and transnational work: joint work of social reproduction and care in Southern Europe

This paper presents the "state of the art" and some of the main issues discussed in relation to the topic of transnational migration and reproductive work in southern Europe. We start doing a genealogy of the complex theoretical development leading to the consolidation of the research program, linking consideration of gender with transnational migration and transformation of work and ways of survival, thus making the production aspects as reproductive, in a context of globalization. The analysis of the process of multiscale reconfiguration of social reproduction and care, with particular attention to its present global dimension is presented, pointing to the turning point of this line of research that would have taken place with the beginning of this century, with the rise notions such as "global care chains" (Hochschild, 2001), or "care drain" (Ehrenreich and Hochschild, 2013). Also, the role of this new agency, now composed in many cases women who migrate to other countries or continents, precisely to address these reproductive activities, is recognized. Finally, reference is made to some of the new conceptual and theoretical developments in this area.
