*Recent evidence suggests that sectoral heterogeneity in price rigidity, combined with production network interdependencies, amplifies the real effects of monetary policy.  Yet, how these amplification mechanisms shape inequality remains an open question. We develop a Multisector Two-Agent New Keynesian model with Input-Output linkages (Multisector TANK-IO) to analyze the real effects of monetary policy in an economy with Hand-to-Mouth households, sectoral heterogeneity in price rigidity, and production network interdependencies. Our findings indicate that the interaction between Hand-to-Mouth households and sectoral heterogeneity in price rigidity further amplifies the real effects of monetary policy, with the real wage channel playing a central role. Moreover, consumption inequality becomes more countercyclical when price adjustment frequencies vary across sectors. Once production network interdependencies are introduced, monetary policy effects are even more amplified, but consumption inequality becomes less countercyclical, as lower real interest rates stimulate additional spending by Savers' households through the intertemporal substitution channel, while the real wage channel becomes more muted. In the final step, I aim to characterize the optimal monetary policy in the presence of these multiple sources of heterogeneity.

**The rapid rise of social media (SM) use among youth has raised significant concerns about its impact on their development and well-being. This project explores how to support parents in managing their children’s SM usage to mitigate risks and promote positive outcomes. We investigate the diversity in parenting practices and beliefs about SM and evaluate whether evidence-based information can influence these practices. Using a representative sample of UK parents with children aged 10–15, we collect data on parenting strategies, beliefs about SM's effects, and family characteristics. Our findings reveal that more educated parents tend to be stricter and more concerned about SM, with middle school identified as a critical period of heightened parental worry. Additionally, we show that parents’ beliefs about SM significantly influence their practices and their willingness to take preventive action. To test whether beliefs can be shifted, we randomly assign a subset of parents to receive evidence-based information about SM. The intervention successfully changes the beliefs of previously unconvinced parents and increases their intent to act to an extend. In the next phase, we will assess the intervention’s impact on actual parenting practices, aiming to offer actionable insights to support families and protect children.
