For causal identification, we exploit quasi-random variation in electoral exposure across cohorts and birth months, combining election timing with the age-based voting eligibility threshold. Our empirical strategy implements a difference-in-differences design comparing students above and below the voting age in cohorts exposed and not exposed to elections during their final school year. The study contributes to the enfranchisement literature by focusing on non-political outcomes and highlighting a potential civic channel influencing human capital investment. Preliminary findings point to effects on short-term academic performance and field-of-study choices, with heterogeneous patterns across gender.

With the increasing availability of large language models (LLMs), individuals can now outsource the writing of apologies, potentially altering both their content and social meaning. In online experiments, this paper studies how LLM-generated apologies differ from human apologies, how they are evaluated, and whether individuals anticipate these differences when choosing how to apologize. We show that LLM apologies are less variable and more prototypical, relying more heavily on canonical apology strategies that are psychologically costly for humans. When the origin of an apology is undisclosed, LLM and human apologies are similarly effective at eliciting forgiveness. However, a difference emerges with disclosure, highlighting a penalty for machine-generated apologies. We further examine whether individuals anticipate these dynamics when choosing how to generate an apology. Under disclosure, participants are more likely to write an apology themselves than to use a prewritten LLM-generated apology. Importantly, we observe a similar pattern when the prewritten alternative is human-generated. This suggests that individuals anticipate a penalty for using prewritten apologies per se, rather than a penalty specific to machine origin. Consistent with this interpretation, these effects are fully absorbed once participantsrsquo; beliefs about relative effectiveness are controlled for, indicating that apology-generation choices are driven by beliefs rather than disclosure or origin per se. Overall, we show that LLMs produce apologies that are instrumentally effective but potentially socially fragile when their origin is disclosed. Rather than expanding expressive capacity, LLMs appear to reshape apology and forgiveness outcomes by shifting beliefs about effort and authenticity, thereby altering how actions are interpreted.

Event-study and fixed-effects models reveal a distinct temporal decoupling between these dimensions. New parents experience immediate declines in subjective wellbeingmdash;specifically regarding leisure, income satisfaction, and self-assessed health. Conversely, parents exhibit more favorable biomarker profiles across immune, cardiovascular, and metabolic systems, alongside a slower pace of biological aging. While subjective penalties peak when children are young, physiological advantages emerge gradually and persist into later adulthood. Robustness tests confirm these divergent patterns are not driven by socioeconomic strain or psychological distress, which cause convergent deterioration across subjective and biological domains. Instead, parenthood generates a temporal decoupling where subjective experience and biological adaptation follow distinct trajectories. These findings emphasize the necessity of integrating social-science and biological perspectives to understand how the demands of caregiving are physically embedded over the life course.

While the theoretical literature is well developed, the empirical literature is much less so (with some notable exceptions). In this work we perform an empirical analysis of the large-scale behavior of the U.S. public equity universe, with a focus on the role of listing and delisting events. Such events have a profound impact on the distribution of capital. They can also produce severe biases in various statistical procedures that do not take these events into account. This phenomenon explains certain counterintuitive results that can arise when standard SPT models are calibrated to observed volatilities, collision rates, and long-term capital distributions. We develop procedures that correct for these biases, and find that our corrected estimates are remarkably consistent with the relationship between volatilities, local correlations, collision rates, and particle densities predicted by very simple diffusion models. Finally, we identify a mechanism by which listings and delistings can stabilize an otherwise unstable particle system. This is joint work with David Itkin and Licheng Zhang.

Using administrative records from four private pension funds in Italy, we document that women are 8 percentage points less likely than men to choose stock-focused investment lines at enrollment. To assess whether advisory behavior contributes to this gap, we conduct a vignette-based survey experiment among pension advisors affiliated to the four funds, randomly varying the gender of otherwise identical prospective clients. Advisors are 22 percentage points less likely to recommend stock-oriented portfolios to females, even after conditioning on advisors#39; beliefs about relevant client characteristics. We further show that a simple information intervention that makes advisors aware of the documented gender bias eliminates this gap in the experimental setting. Linking advisors to real clients in the administrative data, we demonstrate that the gender gap in actual investment choices shrinks by approximately 60% during the five months following the intervention. This evidence suggests that gender bias in financial advice is largely implicit and that low-cost informational feedback to advisors can meaningfully reduce gender disparities.

We propose the Self-Confirming Opportunity Model (SCOM), an intrapersonal equilibrium concept. In a SCOM each alternative is paired with the option chosen from the remaining menu as its opportunity cost, and choice maximises a menu-independent quaternary preference over such pairs. We provide a revealed-preference characterisation of this model. SCOM accommodates cyclical choice, Condorcet inconsistencies and choice overload patterns within a disciplined maximisation framework. Standard rational choice obtains if and only if the underlying quaternary preference satisfies a coherence condition, yielding a strict order over alternatives.
