We construct a tractable general equilibrium model of cumulative innovation and growth, in which new ideas strictly improve upon frontier technologies, and productivity improvements are drawn in a stochastic manner. The presence of positive knowledge spillovers implies that the decentralized equilibrium features an allocation of labor to R&D activity that is strictly lower than the social plannerś benchmark, which suggests a role for patent policy. We focus on a "non-infringing inventive step" requirement, which stipulates the minimum improvement to the best patented technology that a new idea needs to make for it to be patentable and non-infringing. We establish that there exists a finite required inventive step that maximizes the rate of innovation, as well as a separate optimal required inventive step that maximizes welfare, with the former being strictly greater than the latter. These conclusions are robust to allowing for the availability of an additional instrument in the form of patent length policy.

Abstract
This article aims to explore the political economy of trans life through an examination of the category of the "femboy" as a means for understanding the concrete processes of sexuality and social activity responsible for the internally differentiated valuation of kinds of trans labor and the wider regime of accumulation of which these valuations form a part. Following Kevin Floyd's historical materialist account of gendered performativity, it details the femboy's historical emergence within hierarchies of racialized sexuality. Using the case of online streaming, the article argues that femboys' disavowal of transness, and intelligibility to dominant regimes of sexuality, subtends their higher valuation than trans women in comparable lines of work. Making use of the case study, the article argues that identification itself appears to affect the judgment and valuation of individuals within the labor process and that such aesthetic judgements—the contours of how capital "sees" its subjects—are both ineliminable and constitutive of the concrete differences that emerge in the process of production. Aesthetic judgment and the process of abstraction therefore offer an entry point into both the analysis of the labor process more generally, and the relations of desire, abjection, and identification that enforce the present subordination of trans people.

Postprint of: Phoenix, D. (2020). Black Hope Floats: Racial Emotion Regulation and the Uniquely Motivating Effects of Hope on Black Political Participation. Journal of Social and Political Psychology. ; Drawing upon theories of group based emotion, group based efficacy and appraisal, I propose a model of racial emotion regulation to explain variations in how Black and White Americans respond emotionally and behaviorally to policy opportunity cues. I test the major claims of this model with data from an original experiment and national survey. Findings from the studies indicate that expressions of hope carry a strong and consistent mobilizing effect on the political participation of African Americans, while producing null effects on White participation. I discuss the implications of this model for our understanding of the potential of hope to shape appraisals and perceptions of efficacy among socially marginalized groups, opening up a distinct pathway through which they can be mobilized for political engagement. ; This research was supported in part by a grant from the Alliances for Graduate Education and the Professoriate (AGEP). ; peerReviewed ; acceptedVersion

Ce papier examine le lien entre éducation publique et croissance économique à l'aide d'un modèle à deux secteurs, dans lequel l'agent consomme un bien manufacturé et des services. Lorsque l'éducation publique est financée par des taxes sectorielles, la politique éducative qui maximise le taux de croissance diffère de celle dictée par un financement uni-sectoriel. Deux mécanismes expliquent cela. Tout d'abord, les préférences des agents en capital humain, en service et en épargne affectent la relation croissance-éducation publique dès lors que des taxes sectorielles sont considérées. Ensuite, ce type de financement crée une distorsion, en modifiant le prix relatif de l'éducation, qui est supposée être un bien de services. Nous montrons ainsi qu'un financement de l'éducation publique par des taxes sectorielles peut conduire à un taux de croissance de long-terme plus élevé qu'une taxe sur la production agrégée.
