Spillover effects across values

Job Market Paper | Working Paper

Abstract: Values characterize preferences that themselves shape individuals’ decisions explaining future gaps in economic outcomes. I study the dynamics of values when values are inter-dependent and shocked by life events and I show that spillover effects across values do exist. Individuals choose to identify with a group with which they share values, but there are psychological costs to have values that are not consistent with those of the group. Whenever an event occurs in someone’s life—bringing new information—this may change some of her values. This shock can drive the individual to identify with a new group if the shocked values have taken her too far from her previous group. By identifying with the new group, she changes all her values—including not initially affected values—toward those of that new group. By changing values that are not affected by the shock, life events generate spillover effects across values.

Inter-generational conflict and the declining labor share

Under review at the Journal of Economic Dynamics & Control | Working Paper

Abstract: The coincidence in timing between the start of the decline of the labor share and the entry of the baby-boomers cohort into adulthood—entering the labor market and reaching voting age—has received no attention. I argue that the observed shift away from labor toward capital is a response to changes in labor market institutions endogenously determined by the age structure of the population through voting. The size of the boomer cohort gives them large political weight and allows them to change public policy in their favor when they are young and then old. These institutional changes have consequences for the wage bargaining to which firms respond by substituting labor with capital to thwart workers’ appropriation of the rents. I develop a model which links public policy to wage bargaining and calibrate it for France and the US. Numerical simulations can replicate the decline of the labor share and labor market dynamics.

Spreading the polarization disease: From the labour market to social mobility

with Cecilia García-Peñalosa and Tanguy van Ypersele | Working Paper

Abstract: The increase in employment polarization observed in a number of high-income economies has coincided with a reduction in inter-generational mobility. This paper uses data for two British cohorts that entered the labour market at two points in time that differed considerably in terms of the structure of employment to re-examine the drivers of mobility. We differ from the existing literature in two aspects. First, we focus on employment categories rather than income, thus obtaining dynamics that can be understood in terms of changes in the structure of employment. Second, we argue that understanding inter-generational dynamics requires considering how individuals move from their entry jobs into other employment categories, i.e. understanding intra-generational mobility. The data indicate that occupational changes over the individual’s career are an important source of mobility, with large shares of those in low-paying (respectively, middling) occupations moving into middling (resp. high-paying) ones. When we compare the two cohorts we find that these two sources of mobility have declined for the younger cohort and that, whatever the initial occupation, parental income has become more important in leading to occupational upgrading. Moreover, the impact of parental income increased the most in the regions where the share of middling employment fell the most, suggesting that increased employment polarization may be one of the factors behind the observed decline in mobility.
