Inflation in Theory and Practice: A Comprehensive Review of the Literature From the Great Inflation to the 2020s Surge

Journal of Economic Surveys, EarlyView.
ABSTRACT The post‐pandemic inflationary spike brought inflation back to the forefront of academic research. In the debate about the origin and nature of the 2020s inflation, economists have been divided into the following two main camps: the demand‐pull camp, which attributed inflation to excess demand and linked it to fiscal and monetary stimulus put ...

Aggregate Market Power: Measurement, Drivers, and Macroeconomic Effects

Journal of Economic Surveys, EarlyView.
ABSTRACT This survey reviews the macroeconomic literature on market power, focusing on its measurement, determinants, and macroeconomic effects. It synthesizes evidence from concentration ratios, business dynamism indicators, and markup/markdown estimates, documenting a distinct change in trends since the 1980s, especially in the United States ...

How Brokers Enable Collective Identity Formation in Fragmented Industry Groups: The Case of Franciacorta Wineries

Journal of Management Studies, EarlyView.
Abstract This study illuminates the role of brokers, that is, actors spanning inter‐organizational boundaries, in the process of collective identity formation in fragmented industry groups. Through an in‐depth longitudinal analysis of the Franciacorta wineries from the 1960s to the 1990s, we uncover how technical consultants acting as brokers ...

Density‐Valued ARMA Models by Spline Mixtures

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper proposes a novel framework for modeling time series of probability density functions by extending autoregressive moving average (ARMA) models to density‐valued data. The method is based on a transformation approach, wherein each density function on a compact domain [0,1]d$$ {\left[0,1\right]}^d $$ is approximated by a B‐spline ...

On the Existence of One‐Sided Representations for the Generalised Dynamic Factor Model

Journal of Time Series Analysis, EarlyView.
ABSTRACT We study the Generalised Dynamic Factor Model (GDFM) and show that the dynamic common component, that is, the common component of the GDFM, can be expressed using only current and past observations under mild assumptions. Specifically, we require (i) the dynamic common component to be purely non‐deterministic and (ii) the exclusion of ...
