Extremely Fast Maximum Likelihood Estimation of High‐Order Autoregressive Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT We consider the problem of exact maximum likelihood estimation of potentially high‐order (p>50$$ p>50 $$) autoregressive models. We propose an extremely fast coordinate‐wise algorithm for fitting autoregressive models. This fast algorithm exploits several properties of the negative log‐likelihood when parameterised in terms of partial ...

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 ...

Genre and Conversation

Noûs, EarlyView.
ABSTRACT Conversations can belong to different types, or genres. We consider four dimensions of variation as case studies: Some conversations are about sharing information, others about making decisions; some are about making firm commitments, others about brainstorming options; some are about sticking to the facts, others involve make‐believe; some ...

Small understory trees increase growth following sustained drought in the Amazon

New Phytologist, EarlyView.
Summary Droughts pose a major threat to the Amazon rainforest, yet the mechanisms enabling trees to maintain growth under prolonged drought remain poorly understood, particularly in the understory layer. We leveraged a 22‐yr Throughfall Exclusion (TFE) in a 1‐ha plot in eastern Amazonia, paired with a Control plot, to test whether small understory ...

A Long‐Run Perspective on Unconditional Convergence in Manufacturing: Evidence From U.S. Industrialisation

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper examines long‐run unconditional convergence of labour productivity in manufacturing across 48 contiguous U.S. states. We construct a detailed panel data set of state‐industry pairs with over 120 industries covering the period 1880–2007.
