Labor market duality refers to the coexistence of temporary workers with low dismissal costs and permanent workers with high dismissal costs within the same firms. The prevalence of temporary employment is a common feature in several countries, such as Continental European countries. Further, since the 1980s, the Japanese labor market has been experiencing a substantial increase in temporary jobs. The quality of temporary jobs tends to be lower than that of permanent jobs (e.g., the former includes lesser job security, lower wages, and fewer training opportunities compared to the latter). For this reason, the causes and consequences of widespread temporary employment have both policy and academic implications. To date, most of the research on this topic has focused on the supply side of labor markets (demographic changes in workforce), macroeconomic impacts (business cycles), and labor-market institutions. However, since the majority of temporary workers tends to be involuntary, the demand-side analysis is important, as well. It has rarely been examined how market competition would affect firms’ demand for temporary and permanent labor, particularly within the context of economic globalization.

Our study attempts to fill this gap. By proposing a heterogeneous-firm trade model with a dual labor market, we examine the relations between the demand for temporary and permanent workers and economic globalization. Our model highlights intensified product market competition as a driving force behind the shift in demand from permanent to temporary workers. In addition, our model demonstrates that international outsourcing effectively reduces labor adjustment costs, which decreases the demand for permanent workers. Using industry-level data from the Japanese manufacturing sector, we empirically test the relations between the demand for temporary and permanent workers and economic globalization and find that they support most of our theoretical predictions.

The Effects of U.S. School Shootings on Children’s Antidepressant Use

More than 220,000 American students have experienced a school shooting since the 1998 Columbine High massacre. School shootings are vastly more common in the U.S. than in any other developed country, and are becoming more frequent and deadly in recent years. While these events receive widespread media coverage and incite public debates, there is little empirical research quantifying their population-level mental health impacts. We combined data on 44 school shootings between January 2008 and April 2013 with data on antidepressant prescriptions filled at retail pharmacies between January 2006 and March 2015. We compared the number of antidepressants prescribed to children under age 20 by providers located in close proximity of a school that experienced a shooting (shooting-exposed area) to those prescribed to children by providers located slightly further away (reference group), both in the two years before and the two years after a shooting. The average number of monthly antidepressant prescriptions written to children was significantly higher in the shooting-exposed areas relative to the reference groups in the two years after a fatal shooting versus the two years before. The effect persisted when extending the post-shooting observation window to three years and was similar when using an alternative reference group of providers located in close proximity to observationally similar schools without a shooting. We found no significant effects on children’s antidepressant prescriptions following non-fatal shootings or on adult antidepressant use. Our results suggest that local exposure to fatal school shootings increases antidepressant use among children under 20 years old, a previously unmeasured cost of these events.

Bio: Dr. Arvind Gupta recently retired as India's Deputy National Security Advisor. In his capacity as Deputy NSA, he also headed India's National Security Council Secretariat from 2014 until 2017. Previously, he was the Director General of the Institute for Defence Studies and Analysis (IDSA), a thinktank funded by India's Ministry of Defence. Dr. Gupta joined the Indian Foreign Service in 1979 and served at India's diplomatic missions in Moscow, London and Ankara. At the Ministry of External Affairs in New Delhi, he dealt with Afghanistan, the Soviet Union, Russia, Kashmir, and the Central Asian affairs. He is an honorary professor in the Department of Defence and National Security Studies, Panjab University. He has an MSc in Physics from the University of Delhi and a Ph.D. in International Relations from Jawaharlal Nehru University. He is currently the Director of Vivekananda International Foundation (VIF), a Delhi-based independent, non-partisan think tank focussing on foreign policy, defense and security-related issues from an Indian perspective. His most recent book How India Manages its National Security was published by Penguin Random House in 2018.

Book Overview: In this authoritative and comprehensive survey of the challenges a changing global security environment poses to India, former deputy national security advisor Arvind Gupta outlines the important aspects of the country's security apparatus and how they interface to confront internal and external conflicts. We have today a turbulent Middle East to the west; a rising and assertive China to the north; Pakistan in the grip of the military and the militants across our border and an increasingly militarizing Indian Ocean region surrounding us. Additionally, climate change, cyber security and the vulnerability of our space assets are major areas of concern. Anything that weakens a nation weakens its security, which makes the issues of food, water, health, economics and governance critically significant. Arvind Gupta draws on his long experience in these areas to argue that instead of tactical remedies, a strategic, coherent, institutional approach is needed to deal with these challenges. Strengthening the National Security Council, for instance, could be one way forward.

How India Manages Its National Security explains with great clarity and thoroughness the concept and operation of India's national security apparatus. This book will be of great interest to practitioners, analysts and laymen alike and offer an important voice in the discussion on how national security challenges should be resolved in the decades to come.

This study focused on an important but often overlooked aspect of safety in medicine: physician safety. In China, patients may violently protest against doctors via disruptive behaviors when facing unsatisfying results, jeopardizing physicians’ security, affecting their diagnostic reasoning, and ultimately harming patient safety. We investigated the relationship between disruptive behaviors, government intervention, and protest results. Statistical analyses reveal that the ‘paying for peace’ mechanism can create distorted incentives for patients and encourage more riots. Efforts should be made to improve service quality and channel medical disputes into the legal framework.
