As countries develop and experience structural transformation, the gendered patterns of labor change. We use harmonized labor force data and do not find evidence that women's share of the agricultural labor force is positively correlated with per capita income. Yet, the evidence shows many changes taking place that vary across locations. We identify five areas that require attention to understand these processes of change: the patterns of joint ownership and management among smallholder farmers, the responses to the migration of men off-farm, shifts across sectoral boundaries, time spent on domestic services and care work, and the impact on empowerment. It is important to go beyond the number of people employed in production agriculture to understand the many ways that the gendered patterns of labor are changing.
In this article, we obtain an extension of the Ekeland variational principle in quasi-uniform spaces. Since the Ekeland variational principle is a type of perturbed optimization problem, the perturbations do not need to satisfy the triangle property to obtain results. We also give some equivalent results of our main results. Moreover, we present a new version of the Ekeland variational principle and its equivalent results, in the setting of quasi-gage spaces. Finally, we establish the Ekeland variational principle in a (metric) modular space as an application of our results.
We investigate how the incompleteness of an employment contract—discretionary and noncontractible effort—can affect an employer’s decision about cutting nominal wages. Using matched employer-employee payroll data from Great Britain linked to a survey of managers, we find support for the main predictions of a stylized theoretical framework of wage determination: nominal cuts are at most half as likely when managers believe that their employees have significant discretion over how they do their work, although the involvement of employees, via information sharing, reduces this correlation. We also describe how contract incompleteness and wage cuts vary across different jobs. These findings provide the first observational quantitative evidence that managerial beliefs about contractual incompleteness can account for their hesitancy over nominal wage cuts. This has long been conjectured by economists based on anecdotes, qualitative surveys, and laboratory and field experiments.

A considerable body of work has shown that motherhood is accompanied by a reduction in labor market participation and hours of market work, while more recent findings indicate that women who earn more than their husbands tend to subsequently take actions that reduce their market income. Both patterns of behavior have been interpreted as women trying to conform to child-rearing norms and to the prescription that the husband should be the main breadwinner. In this paper, we use panel data for US couples to re-examine women's behavior when they become mothers and when they are the main breadwinner. We start by asking whether the arrival of a child affects women who are the main breadwinner and those who are not in the same way, and then turn to how mothers and childless women react when they are the main breadwinner. Our results are consistent with the breadwinner norm only affecting mothers, suggesting that the salience of gender norms may depend on the household's context, notably on whether or not children are present. Concerning the arrival of a child, we find that although the labor supply of women who earn more than their husbands initially responds to motherhood less than that of secondary earners, the two groups converge after 10 years. Moreover, women in the former category exhibit a disproportionately large increase in the share of housework they perform after becoming mothers. The latter results suggest that the presence of children pushes women to seek to compensate breaking a norm by adhering to another one.
This paper develops a search and matching framework in which workers are characterised by asymmetric reference-dependent reciprocity, and firms set wages by considering the effect that these can have on workers’ effort, and therefore on output. The cyclical response of effort to wage changes can considerably amplify shocks, independently of the cyclicality of the hiring wage, which becomes irrelevant for unemployment volatility; and firms’ expectations of downward wage rigidity in existing jobs increases the volatility of job creation. The model is consistent with evidence on hiring and incumbents’ wage cyclicality, and provides novel predictions on the dynamics of effort.
Aims: we propose a sociotechnical taxonomy for the analysis of socio-economic disruptions caused by technological innovations. Methodology: a transdisciplinary principled approach is used to build the taxonomy through categorization and characterization of technologies using concepts and definitions originating from cybernetics, occupational science, and economics. The sociotechnical taxonomy is then used, with the help of logical propositions, to connect the characteristics of different categories of technologies to their socio-economic effects, for example their externalities. Results: we offer concrete illustrations of concepts and uses, and an Industry 5.0 case study as an application of the taxonomy. We suggest that the taxonomy can inform the analysis of opportunities and risks related to technological disruptions, specially of those that result from the rise of cognitive machines.
Salience theory relies on the assumption that not only the marginal distribution of lotteries, but also the correlation of payoffs across states impacts choices. Recent experimental studies on salience theory seem to provide evidence in favor of such correlation effects. However, these studies fail to control for event-splitting effects (ESE). In this paper, we seek to disentangle the role of correlation and event-splitting in two settings: 1) the common consequence Allais paradox as studied by Bordalo et al. (2012), Bruhin et al. (2022), and Frydman and Mormann (2018); 2) choices between Mao pairs as studied by Dertwinkel-Kalt and Köster (2020). In both settings, we find evidence suggesting that recent findings supporting correlation effects are largely driven by ESE. Once controlling for ESE, we find no consistent evidence for correlation effects. Our results thus shed doubt on the validity of salience theory in describing risky behavior.
The paper examines the question of non-anonymous Growth Incidence Curves (na-GIC) from a Bayesian inferential point of view. Building on the notion of conditional quantiles of Barnett (1976. “The Ordering of Multivariate Data.” Journal of the Royal Statistical Society: Series A 139: 318–55), we show that removing the anonymity axiom leads to a complex and shaky curve that has to be smoothed, using a non-parametric approach. We opted for a Bayesian approach using Bernstein polynomials which provides confidence intervals, tests and a simple way to compare two na-GICs. The methodology is applied to examine wage dynamics in a US university with a particular attention devoted to unbundling and anti-discrimination policies. Our findings are the detection of wage scale compression for higher quantiles for all academics and an apparent pro-female wage increase compared to males. But this pro-female policy works only for academics and not for the para-academics categories created by the unbundling policy.
Le projet de Philippe Grill est d’enquêter sur les origines et les fondements des doctrines et théories relatives aux libertés et à l’égalité. Son approche est proprement philosophico-économique, au sens où elle s’appuie sur l’une et l’autre discipline. Cette exploration conceptuelle des théories économiques et philosophiques, des hypothèses qui les fondent, des notions qui les irriguent, ou encore des masses de données empiriques aux interprétations multiples, voire contradictoires, se révèle cruciale car c’est à partir de ces doctrines et théories que sont conçues et promues les organisations sociales et les politiques publiques qui déterminent « dans quel monde on vit », en décrétant le possible et l’impossible en ces domaines. L’ouvrage contribue ainsi pleinement aux débats actuels d’éthique sociale en fournissant les moyens de définir ce que pourrait être une organisation sociale « humaniste ».
En effet, si l’on veut changer le monde, il faut le comprendre… Sereinement, pédagogiquement, c’est notamment à cette compréhension maximale que nous invite Philippe Grill. La somme encyclopédique qu’il nous propose déploie le panorama d’une philosophie économique où sont convoqués les savoirs contemporains issus de nombreuses disciplines (outre les sciences économiques bien sûr, les autres sciences sociales, la logique, l’épistémologie, les sciences cognitives, les neurosciences, la biologie de l’évolution, etc., ainsi que les engagements ontologiques des nombreux penseurs que l’ouvrage étudie). Ici, point de simple juxtaposition de disciplines, mais une architecture des connaissances qui veut montrer que les conceptions idoines sont nécessairement connexes si l’on entend démêler l’écheveau d’un homo œconomicus authentique, renversant le modèle factice que rabâchent les propagandistes de vulgates économiques outrancièrement simplistes et irréalistes. Ainsi, ce livre est un puissant levier de ce mouvement salutaire. Moins
