Decline in Youth Participation in Canada in the 1990s: Structural or Cyclical?
Of the three major age groups, youth (aged 15-24), experienced the largest fall in labour force participation and accounted for the lion’s share of the aggregate decline. Consequently, an understanding of the factors behind this development is essential to an overall understanding of the fall in labour force participation in the 1990s in Canada. In the fifth and final article in the symposium, Richard Archambault and Louis Grignon examine the causes of this large fall in youth labour force participation in Canada in the 1990s. They disaggregate the youth participation rate into three components: the student participation rate, the non-student participation rate, and the school enrolment rate. The aggregate youth rate is the sum of the student and non-student rates weighted by their respective shares of the population (the enrolment rate for students). Such an approach makes it possible to take account of behavioural differences between students and non-students and to treat the enrolment rate as a phenomenon to be explained rather than a determinant of the participation rate. All three variables are modelled as a function of a cyclical variable and a number of structural variables - the real wage, the relative minimum wage, employment insurance, social assistance, and a time trend. The results show the importance of economic conditions and the modest effect of public policy programs on the decision to participate in the labour market and go to school. Based on the equations estimated for the 1976-96 period, a dynamic simulation was conducted over the 1990-96 period to account for the impact of the variables on the student and non-student participation rates and enrolment rate. According to the equations estimated for the 15-24 age group, the cyclical variable accounts for about one half of the decline in the youth participation rate between 1990 and 1996, two thirds of the decline in the student participation rate, and about one third of the fall in both the non-student participation rate and rise in the enrolment rate. The remaining decline in the two participation rates and rise in the enrolment rate are not to any significant degree explained by the four structural variables, but rather are either captured by the time trend or not explained at all. Given these results, the authors conclude that we have a poor understanding of the non-cyclical forces that account for up to one half of the decline in youth labour force participation in the 1990s.Canada, Labour Force Participation, Labor Force Participation, Participation Rate, Labour Force Participation Rate, Labor Force Participation Rate, Age Structure, Age, Youth, Teenage, Young Adult, Student, Enrolment Rate, Enrolment, Enrollment Rate, Enrollment
Demographic Shifts and Labour Force Participation Rates in Canada
Labour force participation rates vary greatly by age, with persons 55 and over having much lower participation rates than younger persons. Consequently, changes in the demographic composition of the population can exert a long-run effect on aggregate participation rates. In the third article of the symposium, Bob Dugan and Benoît Robidoux examine the impact of demographic shifts on labour force participation in Canada. They use an accounting framework and plausible trend participation rates for 16 demographic groups with source population estimates to estimate an aggregate structural participation rate for Canada. They find that the ageing of the population has already started to exert downward pressure on the aggregate participation rate in Canada due to longer life expectancy and the resulting growing proportion of the population in the low-participation rate 65 and over age group. The movement of the baby boom generation into the 65 and over group in coming years will intensify this trend. Between 1989 and 1997 they find that the demographic composition effect reduced the aggregate participation rate by almost 1 percentage point, and that from now to 2030 it will reduce the participation rate by an additional 8.5 points. Of course, greater than expected trend increases in labour force participation rates by older age groups could offset some of this composition effect. The authors point out that changes in demographic composition had virtually no effect on the participation rate in the 1990s in the United States as the share of the population 65 and over was stable. This situation reflects the fact that the United States became an “older” society earlier than Canada due to an earlier and smaller baby boom and a higher average age for immigrants. Dugan and Robidoux calculate a trend participation rate of 66.2 in 1997, 1.4 percentage points above the actual rate of 64.8 per cent. Based on this rate they conclude that about one half of the 2.7 point decline in the participation rate in the 1990s was structural and one half cyclical.Canada, Labour Force Participation, Labor Force Participation, Participation Rate, Labour Force Participation Rate, Labor Force Participation Rate, Age Structure, Age, Sex, Gender, Aging, Ageing
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The Changing Labour Force Participation of Canadians, 1969-96: Evidence from a Panel of Six Demographic Groups
Cyclical, policy changes, and structural factors have been put forward to explain the decline in labour force participation in Canada in the 1990s. In the first article in the symposium, Pierre Fortin and Mario Fortin attempt to determine the relative importance of these three types of factors by estimating a participation rate equation where the independent variables are an index of job availability (the Help-Wanted Index), the real wage, the real minimum wage, an index of unemployment insurance generosity, real social assistance benefits, and a time trend to capture other structural influences. The equation is estimated for six demographic groups (men and women 15-24, 25-54 and 55 and over) over the 1969-96 period. They find that the drop in the aggregate participation rate in the 1990s was equally due to the three factors: poor macroeconomic conditions, policy changes in unemployment insurance and the minimum wage, and structural transformations. The explanatory power of the equations is found to be good for the younger and middle-age groups, but poor for the older groups. The equations show no significant shift over the 1990-96 sub-period, implying that the decline in the participation rate in the 1990s should not be attributed to a new structural relationship. In terms of the variables, the authors find that young people, and to a less extent, middle-aged persons, respond positively to cyclical variations in job opportunities, but older persons do not; minimum wages affect negatively the labour force participation of the younger age groups and middle-aged women; UI generosity affects positively only youth participation; and social assistance affects negatively the participation of middle-aged women. The authors use their equations to simulate the impact of changes in cyclical, policy, and structural variables on labour force participation of the six groups in the 1990-97 period. The model can account for 2.6 percentage points of the total 2.7 percentage point decline in the aggregate participation rate between 1989 and 1997. Reduced job availability was responsible for 37 per cent of the decline, increases in the real minimum wage 15 per cent, decreased UI generosity 19 per cent, falls in social assistance benefits made a 4 per cent negative contribution to the decline in participation, and structural factors accounting for the remaining 30 per cent of the decline. These structural factors included rising school attendance, the changing roles of men and women in society, the changing demand and supply of skills, the expansion of public pension plans, and the rising average age of the 55 and over group. The simulations explained quite well the evolution of labour force participation for all groups except older males. Perhaps surprisingly, none of the large decline in participation of this group was found to be due to reduced job availability. The finding that only about 40 per cent of the decline in labour force participation in the 1990s is cyclical has important implication for the path of potential output. The authors find that whatever the value of the non-accelerating inflation rate of unemployment (nairu), in a non-inflationary cyclical recovery, the participation rate is unlikely to rise more than 0.8 percentage points from the 1997 level of 64.8 per cent.Labour Force Participation, Labor Force Participation, Participation Rate, Labour Force Participation Rate, Labor Force Participation Rate, Canada, Output Gap, Potential Employment, Potential Output, Potential Growth, Forecast, Simulation
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
