An Introduction to Sequential Decision Problems
(Mandatory for the first-year Ph.D. Students)

Room A6, Contrada S. Chiara, 50
Abstract
This short lecture introduces stochastic dynamic programming as a framework for modeling and solving sequential decision problems under uncertainty. Participants will learn how to formulate a problem as a Markov decision process, interpret decision trees, and understand the value function and backward induction. Because exact solutions are often impractical, the session surveys practical policy design strategies, including policy, cost, and value function approximations, as well as direct lookaheads. The lecture also introduces dual bounds and information relaxations as tools for benchmarking policies and quantifying optimality gaps. Examples from dynamic delivery and routing illustrate how these ideas translate into implementable decision rules in practice.

Abstract
Bayesian nonparametric inference has become an increasingly important paradigm in modern statistics, providing a flexible and principled framework for probabilistic modeling and data analysis. By placing prior distributions on infinite-dimensional objects, Bayesian nonparametric methods allow for accurate estimation of complex functions such as probability distributions, regression functions, and hazard rates. Rooted in de Finetti’s foundational work on exchangeability, the field has evolved through key methodological developments, most notably the introduction of the Dirichlet process, and has undergone substantial growth over the last two decades, driven by advances in computational algorithms and their successful application to a wide range of challenging problems.
This short course provides an introduction to Bayesian Nonparametric Statistics at the PhD level. It begins with a concise review of the Bayesian paradigm, with emphasis on probabilistic modeling, prior specification, posterior inference, and computation. The assumption of exchangeability is then introduced as a key modeling principle in Bayesian inference, providing a rationale for the use of prior distributions. The Dirichlet process is presented as the most prominent Bayesian nonparametric prior, along with its main theoretical properties and constructive representations. Building on this framework, the course focuses on Dirichlet process mixture models as flexible tools for density estimation and clustering. Extensions beyond the Dirichlet process are subsequently discussed, with particular attention to the Pitman–Yor process and its implications for modeling power-law behavior and richer clustering structures. Computational aspects of Bayesian nonparametrics are addressed throughout the course, including Markov chain Monte Carlo methods as well as marginal and conditional sampling schemes. The theoretical concepts are complemented by concrete examples and hands-on implementations in R, with specific use of the BNPmix package for fitting and exploring Bayesian nonparametric mixture
models.

Great Layoff, Great Retirement and Post-Pandemic Inflation

Abstract
This paper examines how pandemic-induced layoffs contributed to post-Covid-19 inflation through their effects on retirement and labor supply. Using CPS microdata, we show that the unprecedented “Great Layoff” triggered a sharp rise in early retirements – the “Great Retirement” – which increased labor market tightness and nominal wages. Younger non-participants were drawn into employment, partly offsetting the loss of older workers. To quantify this mechanism, we estimate a New Keynesian model with endogenous participation and retirement. Counterfactual simulations show that the Great Retirement accounted for roughly three cumulative percentage points of inflation from 2020 to 2024, with modest GDP effects.
