3 + γ t + δ c + ε i t ( 1 ) where X is routine, abstract, or manual occupation, γ t is the year effect, and δ c is the cohort effect. 14 The age polynomials capture the employment share in each occupation over a worker’s age that is common to all cohorts and constant over time. The year and cohort effects represent upward or downward shifts in the age profiles that are common to all workers in a given year or for workers belonging to the same cohort, respectively

Labor markets in the UK have been characterized by markedly widening wage inequality for lowskill (non-college) women, a trend that predates the pandemic. We examine the contribution of job polarization to this trend by estimating age, period, and cohort effects for the likelihood of employment in different occupations and the wages earned therein over 2001-2019. For recent generations of women, cohort effects indicate a higher likelihood of employment in low-paying manual jobs relative to high-paying abstract jobs. However, cohort effects also underpin falling wages for post-1980 cohorts across all occupations. We find that falling returns to labor rather than job polarization has been a key driver of rising inter-age wage inequality among low-skill females. Wage-level cohort effects underpin a nearly 10 percent fall in expected lifetime earnings for low-skill women born in 1990 relative to those born in 1970.

Gains in labor force participation rates in Chile have slowed in recent years. We examine their determinants using a cohort-model analysis. Allowing for both age- and cohort-specific effects in the context of a seemingly unrelated regression equations (SURE) approach, we find that age factors play an important role in determining participation decisions, especially for males. For females, we find that strong positive time trends dominate the downward pressure from demographics, although those trends have recently dissipated. In addition, we find that both cohort effects and the business cycle shape participation decisions. Using our cohort-based analysis, we construct projections of participation rates, which suggest population aging will put downward pressure on labor inputs, and thus potential output, in coming years. Further increases in female labor force participation—supported by policies— could more than offset the downward pressure from demographics.

The United States stands out among advanced economies with marked declines in labor force participation. National averages furthermore conceal considerable within-country heterogeneity. This paper explores regional differences to shed light on drivers of participation rates at the state and metropolitan area levels. It documents a broad-based decline, especially pronounced outside metropolitan areas. Using novel measures of local vulnerability to trade and technology it finds that metropolitan areas with higher exposures to routinization and offshoring experienced larger drops in participation in 2000-2016. Thus, areas with different occupational mixes can experience divergent labor market trajectories as a result of trade and technology.

This paper uses a life-cycle framework to document new stylized facts about the nexus between job polarization and earnings inequality. Using quarterly labor force data for the UK over the period 2000-2018, we find clear life-cycle profiles in the probability of being employed within each occupation type and wages earned therein. Cohort plots and econometric analysis suggest that labor market outcomes and prospects have gradually worsened for the young. These adverse trends are particularly significant for low-skill women: estimated cohort effects point to a fall in wages within each occupation as well as a lower propensity of being employed in abstract-task occupations. We also find evidence of general occupational downgrading in the UK, with more educated workers taking up fewer high-skill occupations than they did in the past. Our analysis informs the policy debate over appropriate measures needed to reduce skill mismatches and alleviate labor market transitions.

Advanced economies are in the midst of a major demographic transition, with the number of elderly rising precipitously relative to the working-age population. Yet, despite the acceleration in demographic shifts in the past decade, advanced economies experienced markedly different trajectories in overall labor force participation rates and the workforce attachment of men and women. Using a cohort-based model of labor force participation for 17 advanced economies estimated over the 1985-2016 period, we document a significant role of common patterns of participation over the life cycle and shifts in these patterns across generations for aggregate labor supply, especially in the case of women. The entry of new cohorts of women led to upward shifts in the age participation prole, boosting aggregate participation rates. However, this process plateaued in most advanced economies, with signs of reversal in some. Using the model's results to forecast future participation trends, we project sizable declines in aggregate participation rates over the next three decades due to the aging of the population. Illustrative simulations show that implementing policies encouraging labor supply can help attenuate but may not fully offset demographic pressures.

since FY2002, and by FY2005 was 40 percent for cohorts of Category-1 insured in the 25–35 age bracket. Various factors have been cited to explain the increasing number of people opting out of the pension system, such as heavy contribution rates, myopic behavior, and administrative inefficiencies. The evidence on which factors dominate is not clear-cut. Suzuki and Zhou (2005) do not find a cohort effect where later generations tend to evade more compared to earlier generations. Rather, the authors found a strong tendency for people to lose the incentive to
