This paper develops a two‐sector model of trade in goods and intermediate tasks that differ in tradability and skill intensity. A skill‐abundant country with high productivity is shown to offshore more unskilled tasks than skilled tasks, without relying on a particular correlation structure between tradability and skill intensity. With putty‐clay technology that allows retraining in the long run, transition from the non‐offshoring to the offshoring equilibrium generates wage and employment effects that switch from negative to positive as tradability declines, with the switches occurring at a higher degree of tradability for skilled tasks. This is consistent with the empirical literature.  相似文献

While many studies on the Fourth Industrial Revolution (FIR) focus on efficiency, productivity and economic progress, only a few have considered its ethical aspects. This article tries to contribute to filling this vacuum by providing a comprehensive approach to ethical risks at the workplace. Drawing upon Catholic social teaching (CST)—addressed to all people of good will—it analyzes ethical aspects at the workplace posited by the FIR, and more particularly by Industry 4.0, which is at the core of this revolution. CST emphasizes the dignity of the worker and the necessity to flourish at the workplace. While robots, artificial intelligence, and interconnected technologies are only instrumental, the real subject of work is the worker. This casts specific light on the ethical issues analyzed, including effects on employment, wages and inequality, human quality treatment, relational aspects, safety and health, surveillance on employees, and meaningful work.  相似文献

ABSTRACT

This paper aims to explore the conceptual potential of the Deleuzian notion of the encounter in order to better understand the genealogy of opportunities. We adopt a processual perspective of opportunities. In order to translate this notion to the domain of entrepreneurship, we analysed and interpreted Jean-Marc Vallée’s Dallas Buyers Club. This film follows the creation of the first club in the United States that illegally allowed HIV-positive people to supply themselves with foreign antiretroviral drugs from Mexico or Japan. The article highlights encounters in this process that disturb the entrepreneur’s belief systems and allow him or her to be open to potential opportunity. It finally explores how the encounter may improve our understanding of the political becoming of opportunities within the entrepreneurial process.  相似文献

This study endeavors to enhance political marketing literature about the impact of lobbying on firm performance. Our sample is composed of 140 U.S. firms and spans the years 2007–2014 to encompass the 2007–2009 recession and the subsequent recovery period. Our findings indicate that lobbying expenses positively contribute to firm performance. Also, government contracts in both ways, dollar amount and number of government contracts, act as mediators between lobbying expenses and firm performance. In addition, organizational slack moderates the relationship between lobbying expenses and government contracts. The managerial implications suggest that lobbying expenses can be leveraged as a potent tool for firm performance. Firms with larger lobbying efforts acquired both, higher dollar amounts and a greater number of government contracts.  相似文献

Family income and child outcomes in Canada   总被引:1,自引:0,他引:1  
Abstract.  A positive relationship between income and child outcomes has been observed in data from numerous countries. A key question concerns the extent to which this association represents a causal relationship as opposed to unobserved heterogeneity. We use data from the National Longitudinal Survey of Children and Youth to implement a series of empirical strategies for estimating the existence and size of the effect of income on three measures of cognition. Our results indicate that the effect of income on these outcomes may well be positive, but that it is likely to be smaller than conventional estimates. JEL Classification: I10  相似文献

A hierarchical model of collusion in local public works is presented. A local authority plans to undertake a project, delegating its construction to a construction firm. Both of them know the project's cost. However, the federal government decides whether to subsidize the project without knowing its cost. Therefore, the local authority and the constructor may agree to misreport their private information, in order to benefit from the allocation of federal grants. We show that different collusive behaviors may emerge. Then, we characterize the optimal federal grant policy. Finally, we investigate when constructing (shutting down) useless (valuable) projects is optimal.  相似文献
