This review article tries to answer four questions: (i) what are the stylized facts about uncertainty over time; (ii) why does uncertainty vary; (iii) do fluctuations in uncertainty matter; and (iv) did higher uncertainty worsen the Great Recession of 2007-2009? On the first question both macro...

This paper investigates the relationship between product market competition (PMC) and innovation. A Schumpeterian growth model is developed in which firms innovate ѳtep-by-stepҬ and where both technological leaders and their followers engage in R&D activities. In this model, competition...

We derive robust predictions on the effects of uncertainty on short run investment dynamics in a broad class of models with (partial) irreversibility. When their environment becomes more uncertain firms become more cautious and less responsive to demand shocks. This result contrasts with the...

Patents citations are a potentially powerful indicator of technological innovation. In this paper we describe the IFS-Leverhulme patents dataset that we have constructed by combining information from the US Case-Western Patent database with UK company accounts and share price information from...

What is the optimal form of firm organization during "bad times"? Using two large micro datasets on firm decentralization from US administrative data and 10 OECD countries, we find that firms that delegated more power from the Central Headquarters to local plant managers prior to the Great...

Partnering with the Census we implement a new survey of "structured" management practices in 32,000 US manufacturing plants. We find an enormous dispersion of management practices across plants, with 40% of this variation across plants within the same firm. This management variation accounts for...

We develop a new monthly panel survey of business executives and a new question design that elicits subjective probability distributions over own-firm outcomes at a one-year lookahead horizon. Our Survey of Business Uncertainty (SBU) began in 2014 and now covers 1,500 firms drawn from all 50...

We present a heterogeneous-firm model in which management ability increases both pro- duction efficiency and product quality. Combining six micro-datasets on management prac- tices, production and trade in Chinese and American firms, we find broad support for the model’s predictions. First,...

We present a survey of recent contributions in empirical organizational economics, focusing on management practices and decentralization. Productivity dispersion between firms and countries has motivated the improved measurement of firm organization across industries and countries. There appears...
