The (Non) Impact of Minimum Wages on Poverty: Regression and Simulation Evidence for Canada

We estimate the effect of minimum wages on poverty for Canada using data from the Survey of Labour and Income Dynamics (SLID) for 1997 to 2007 and find that minimum wages do not have a statistically significant effect on poverty and this finding is robust across a number of specifications. Our simulation results, based on the March 2008 Labour Force Survey (LFS), find that only about 30?% of the net earnings gain from minimum wage increases goes to the poor while about 70?% ??spill over?? into the hands of the non-poor. Furthermore, we find that job losses are disproportionately concentrated on the poor. Our results highlight that, political rhetoric not-withstanding, minimum wages are poorly targeted as an anti-poverty device and are at best an exceedingly blunt instrument for dealing with poverty.     

Robust estimation of dynamic fixed-effects panel data models

This paper extends an existing outlier-robust estimator of linear dynamic panel data models with fixed effects, which is based on the median ratio of two consecutive pairs of first-order differenced data. To improve its precision and robustness properties, a general procedure based on higher-order pairwise differences and their ratios is designed. The asymptotic distribution of this class of estimators is derived. Further, the breakdown point properties are obtained under contamination by independent additive outliers and by the patches of additive outliers, and are used to select the pairwise differences that do not compromise the robustness properties of the procedure. The proposed estimator is additionally compared with existing methods by means of Monte Carlo simulations.     

Modeling Longitudinal Obesity Data with Intermittent Missingness Using a New Latent Variable Model

We propose a latent variable model for informative missingness in longitudinal studies which is an extension of latent dropout class model. In our model, the value of the latent variable is affected by the missingness pattern and it is also used as a covariate in modeling the longitudinal response. So the latent variable links the longitudinal response and the missingness process. In our model, the latent variable is continuous instead of categorical and we assume that it is from a normal distribution. The EM algorithm is used to obtain the estimates of the parameter we are interested in and Gauss–Hermite quadrature is used to approximate the integration of the latent variable. The standard errors of the parameter estimates can be obtained from the bootstrap method or from the inverse of the Fisher information matrix of the final marginal likelihood. Comparisons are made to the mixed model and complete-case analysis in terms of a clinical trial dataset, which is Weight Gain Prevention among Women (WGPW) study. We use the generalized Pearson residuals to assess the fit of the proposed latent variable model.     

ECONOMIC INTEGRATION,POLITICAL INTEGRATION OR BOTH?

We study the effects of economic and political integration by presenting a model in which firms compete with each other in both an economic market—where they produce a good and compete for market share—and in a political (rent seeking) market—where they compete for transfers from the government. Growth is driven by firms’ cost‐reducing innovation activity and economic and political integration affect firms’ incentive to innovate differently. In this setting, economic and political integration can be seen as complementary. Economic integration, when not accompanied by political integration, can lead to less innovation and slower growth as firms respond to increased competition in the economic market by focusing more on rent‐seeking activity. When economic integration is accompanied by political integration, innovation and growth will be stronger and welfare higher.     

Framing and immigration through the trump era

For the last decade, undocumented or illegal immigration has been one of the most contested policy issues in the United States, with significant news attention on policies affecting the undocumented population, ranging from deportations to comprehensive immigration reform, the DREAM Act, and Deferred Action for Childhood Arrivals. Despite these prominent and multifaceted policy debates, scholarship on media framing and public opinion remain more focused on the portrayal of immigrants rather than policies affecting them. In general, scholars find that policy frames are far more consequential to public opinion than equivalency frames (variations in how news media describe unauthorized immigrants, either as “illegal” or “undocumented”) or episodic frames (whether news articles are heavy on human‐interest stories rather than policy facts and statistics). Also, negative frames generally have stronger effects than positive frames, and these effects sometimes vary by partisanship and family migration history. Finally, the relative infrequency of powerful frames in news stories, like a life spent in the United States, provides opportunities for advocates to move public opinion on immigration policy. These findings have important implications for future battles over immigration policy in the United States, which show no signs of abating.     

A Long Cycle in Industrial Relations,or: Regulation Theory and Political Economy

ABSTRACT: The main purpose of this paper is to test the Regulation Theory (la Théorie de la Régulation) ‘ on a subject — the long cycle of rigidity/flexibility in labour markets and industrial relations we have experienced between the late sixties and now — that should be one of the central concerns of such a theory, being linked to one of its basic concepts: the Rapport Salarial. Does the theory of regulation help us (more than rival theoretical frameworks do) in explaining why we underwent a rigidity/flexibility cycle? And in explaining why this cycle took such different forms in different countries? In order to achieve this purpose, the author first distinguishes several meanings, or dimensions, or rigidity/flexibility (money and real wage, numerical, functional, intensive, dualistic, geographical) and goes to some length in analysing why comparisons in this field between national industrial relations systems and labour market arrangements are rather difficult to perform. Having done that, the author argues that regulation theory is of little help in understanding our diachronic question — why we went through a flexibility cycle — because such a theory does not make any strong bet on the causes of change in the institutional arrangements of labour markets and industrial relations. On the synchronic question — why the forms of the cycle have been so different cross-nationally — the conclusion is that Regulation Theory can be useful as a focusing device, as an ideal-type, but that a lot of nationally-specific materials have to be added in order to obtain adequate answers. The paper ends up with a methodological discussion on the statute of regulation theory. It is argued that it is neither theory nor history: it is a series of ideal-types of system-integration, connected by ex-post, historical linkages.     

Inside the Locker Room: Male Homosociability in the Advertising Industry

The use of the term homosociability by male employers and employees has been a key issue in the construction and maintenance of the gendered labour market, especially in senior‐level jobs. Male homosociability encompasses the formal old boys' networks and informal clubs or meetings, as well as humour and banter, referred to metaphorically in this article as the locker room. This article examines the locker room and its resulting forms of socializing, socialization, communication and rituals found in the advertising industry. To gain a clearer understanding of how the locker room constructs workplace opportunities, this article draws upon qualitative research and analysis and examines major service occupations in the advertising industry and the executives who inhabit them. Studying the relationship between the locker room and the production process provides additional perspectives on service work in the corporate sector, occupations and gender inequality.
