Benjamin Moll

Benjamin Moll holds the Sir John Hicks Professorship in Economics at the London School of Economics and Political Science (LSE), where he leads research at the intersection of macroeconomics and inequality. He serves as co-editor of the American Economic Review and maintains an active visitor affiliation with the Janeway Institute at the University of Cambridge. His work bridges theoretical innovation with policy-relevant analysis of contemporary economic challenges.

Professor Moll specializes in heterogeneous agent macroeconomics, investigating how micro-level disparities in income and wealth fundamentally reshape aggregate economic outcomes and policy effectiveness. His research integrates advanced computational methods to model complex interactions between financial frictions, asset prices, and distributional dynamics. Key contributions include developing continuous-time frameworks for analyzing inequality and pioneering the HANK (Heterogeneous Agent New Keynesian) model to study monetary policy transmission through household balance sheets.

Analysis of his recent publications (2023-2025) reveals three dominant research thrusts: energy security implications (particularly German responses to Russian gas cutoffs), optimal capital gains taxation under asset price volatility, and foundational challenges to rational expectations in heterogeneous agent models. These works consistently combine theoretical rigor with empirical validation, demonstrating how distributional considerations alter conventional macroeconomic policy prescriptions. His research has directly informed central bank discussions on inequality-aware monetary policy design.
