Abstract

Forecasting macroeconomic variables is key to developing a view on a country's economic outlook. Most traditional forecasting models rely on fitting data to a pre-specified relationship between input and output variables, thereby assuming a specific functional and stochastic process underlying that process. We pursue a new approach to forecasting by employing a number of machine learning algorithms, a method that is data driven, and imposing limited restrictions on the nature of the true relationship between input and output variables. We apply the Elastic Net, SuperLearner, and Recurring Neural Network algorithms on macro data of seven, broadly representative, advanced and emerging economies and find that these algorithms can outperform traditional statistical models, thereby offering a relevant addition to the field of economic forecasting.

Abstract

Le scandale de l'abus sexuel sur les enfants est désormais sur la place publique. Sachant que le risque d'abus existe partout où il y a des enfants et premièrement dans la famille, l'enjeu de la lutte est immense. Si les conséquences de l'abus sexuel sur les enfants sont assez bien connues et prises en charge aujourd'hui, en particulier grâce à la victimologie, il n'en est pas de même en ce qui concerne les auteurs d'abus sexuels, du moins en France. Tel est donc l'objectif de cet ouvrage : nous permettre de comprendre le cheminement mental des auteurs d'abus sexuels, qu'ils soient prêtre, instituteur ou père de famille, mais également nous faire connaître les thérapies qui ont fait leurs preuves, en particulier dans les pays anglo saxons, sans oublier la prise en charge de la dimension spirituelle de la vie des auteurs de ces actes, quand il s'agit de religieux ou croyants. Psychothérapeute et prêtre membre de la Société des Missionnaires d'Afrique (Pères Blancs), l'auteur travaille cette question depuis plus de quinze ans, il accompagne les victimes et participe au traitement des auteurs d'abus sexuels au Canada. Il enseigne à Rome et en Afrique sur la prévention des abus sexuels.

Abstract

Over the last quarter century, no other city like Miami has rapidly transformed into a global city. The Global Edge charts the social tensions and unexpected consequences of this remarkable process of change. Acting as a follow-up to the highly successful City on the Edge, The Global Edge examines Miami in the context of globalization and scrutinizes its newfound place as a major international city. Written by two well-known scholars in the field, the book examines Miami's rise as a finance and banking center and the simultaneous emergence of a highly diverse but contentious ethnic mosaic. The Global Edge serves as a case study of Miami's present cultural, economic, and political transformation, and describes how its future course can provide key lessons for other metropolitan areas throughout the world.

Abstract

Evidence that the automation of routine tasks has contributed to the polarization of labor markets has been documented for many developed economies, but little is known about its incidence in developing economies. We propose a measure of the exposure to routinization—that is, the risk of the displacement of labor by information technology—and assemble several facts that link the exposure to routinization with the prospects of polarization. Drawing on exposures for about 85 countries since 1990, we establish that: (1) developing economies are significantly less exposed to routinization than their developed counterparts; (2) the initial exposure to routinization is a strong predictor of the long-run exposure; and (3) among countries with high initial exposures to routinization, polarization dynamics have been strong and subsequent exposures have fallen; while among those with low initial exposure, the globalization of trade and structural transformation have prevailed and routine exposures have risen. Although we find little evidence of polarization in developing countries thus far, with rapidly rising exposures to routinization, the risks of future labor market polarization have escalated with potentially significant consequences for productivity, growth and distribution.

Abstract

Despite significant headwinds from population aging in most advanced economies (AEs), labor force participation rates show remarkably divergent trajectories both across countries and across different groups of workers. Participation increased sharply among prime-age women and, more recently, older workers, but fell among the young and prime-age men. This pa- per investigates the determinants of these trends using aggregate and individual-level data. We find that the bulk of the dramatic increase in the labor force attachment of prime-age women and older workers in the past three decades can be explained by changes in labor mar- ket policies and institutions, structural transformation, and gains in educational attainment. Technological advances such as automation, on the other hand, weighed on the labor supply of prime-age and older workers. In light of the dramatic demographic shifts expected in the coming decades in many AEs, our findings underscore the need to invest in education and training, reform the tax system, reduce early retirement incentives, improve the job-matching process, and help individuals combine family and work life in order to alleviate the pressures from aging on labor supply.

Abstract

This Selected Issues explores Japan’s experiences with past valued added tax (VAT) rate increases and discusses potential policy options to mitigate the economic impact of a third-rate increase. It assesses the impact on the Japanese economy and, where possible, provides some international context. Alongside possible mitigating policies, it also discusses the importance of policy commitment and credibility, and how they can influence the macroeconomic impact of tax rate changes. Carefully designing policy measures and communicating them clearly to the public are paramount to attenuate any negative outcomes in the short term. A simple, single-rate VAT would efficiently raise tax revenues and support the government’s objective of achieving fiscal consolidation in the medium term. Assuming underlying macroeconomic conditions are favorable, the October 2019 VAT rate increase could potentially have a smaller impact on the economy relative to that of 2014 for several reasons. In order to reduce policy uncertainty and alleviate any adverse impacts from the 2019 VAT rate increase, the authorities should clearly communicate the timing and content of associated mitigating measures.

Abstract

Like American politics, the academic debate over justice is polarized, with almost all theories of justice falling within one of two traditions: egalitarianism and libertarianism. This book provides an alternative to the partisan standoff by focusing not on equality or liberty, but on the idea that we should give people the things that they deserve. Mulligan sets forth a theory of economic justice - meritocracy - which rests upon a desert principle and is distinctive from existing work in two ways. First, meritocracy is grounded in empirical research on how human beings think, intuitively, about justice. Research in social psychology and experimental economics reveals that people simply don’t think that social goods should be distributed equally, nor do they dismiss the idea of social justice. Across ideological and cultural lines, people believe that rewards should reflect merit. Second, the book discusses hot-button political issues and makes concrete policy recommendations. These issues include anti-meritocratic bias against women and racial minorities and the United States’ widening economic inequality. Justice and the Meritocratic State offers a new theory of justice and provides solutions to our most vexing social and economic problems. It will be of keen interest to philosophers, economists, and political theorists.
