Band‐Pass Filtering With High‐Dimensional Time Series. A Synthetic Indicator of the Medium‐to‐Long Run Component of Growth

Journal of Time Series Analysis, EarlyView.
ABSTRACT The paper deals with the construction of a synthetic indicator of economic growth, obtained by projecting a quarterly measure of aggregate economic activity, namely gross domestic product (GDP), into the space spanned by a finite number of smooth principal components, representative of the medium‐to‐long‐run component of economic growth of a ...

Reinforcement Learning for Jump‐Diffusions, With Financial Applications

Mathematical Finance, EarlyView.
ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

The Economic Effects of ‘Excessive’ Financial Deepening

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We study the causal implications of high levels of financial deepening for economic development and banking crises in a panel of countries over the past seven decades. We adopt a factor‐augmented heterogeneous difference‐in‐differences estimator and find, in contrast to the existing literature, that very high levels of financial development do

The Natural Components of a Regular Linear System

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT The analysis of a finite‐dimensional regular linear system may be simplified by separating the system into its natural components. The natural components are smaller linear systems on separate subspaces whose dimensions sum to the dimension of the original linear system.

The Social Origins and Education of the British Civil Service Elite, 1945–2022

Public Administration, EarlyView.
ABSTRACT We provide a fuller account than previously available of the extent of change in the social backgrounds of the British civil service elite from 1945 onwards. We consider our findings in relation to questions of meritocracy in recruitment to the elite and of the representativeness of the elite of the population at large.
