The Brexit Vote, Productivity Growth and Macroeconomic Adjustments in the United Kingdom

Ben Broadbent, Federico Di Pace, Thomas Drechsel, Richard Harrison, and Silvana Tenreyro

The UK economy experienced significant macroeconomic adjustments following the 2016 referendum on its withdrawal from the European Union. To understand these adjustments, this paper presents empirical facts using novel UK macroeconomic data and estimates a small open economy model with tradable and non-tradable sectors.

Taxes and Growth: New Narrative Evidence from Interwar Britain

James Cloyne, Nicholas Dimsdale, and Natacha Postel-Vinay

The impact of fiscal policy on economic activity is still a matter of great debate. And, ever since Keynes first commented on it, interwar Britain, 1918-1939, has remained a particularly interesting and contentious case — not least because of its high debt environment and turbulent business cycle. This debate has often focused on the effects of government spending, but little is known about the effects of tax changes.

Strategic Exploration: Preemption and Prioritization

Qingmin Liu and Yu Fu Wong

This paper analyzes a model of strategic exploration in which competing players independently explore a set of alternatives. The model features a multiple-player multiple-armed bandit problem and captures a strategic trade-off between preemption—covert exploration of alternatives that the opponent will explore in the future—and prioritization—exploration of the most promising alternatives. Our results explain how the strategic trade-off shapes equilibrium behaviors and outcomes, e.g., in technology races between superpowers and R&D competitions between firms.

On the Use of Outcome Tests for Detecting Bias in Decision Making

Ivan A. Canay, Magne Mogstad, and Jack Mountjoy

The decisions of judges, lenders, journal editors, and other gatekeepers often lead to significant disparities across affected groups. An important question is whether, and to what extent, these group-level disparities are driven by relevant differences in underlying individual characteristics, or by biased decision makers. Becker (1957, 1993) proposed an outcome test of bias based on differences in post-decision outcomes across groups, inspiring a large and growing empirical literature.

The Transmission of Commodity Price Super-Cycles

Felipe Benguria, Felipe Saffie, and Sergio Urzua

We examine two key channels through which commodity price super-cycles affect the economy: a wealth channel, through which higher commodity prices increase domestic demand, and a cost channel, through which they induce wage increases. By exploiting regional variation in exposure to commodity price shocks and administrative firm-level data from Brazil, we empirically disentangle these transmission channels.

Supply-side climate policies in the oil market: Higher taxes reduce exploration and discoveries. If only OECD countries adopt this policy, 47–73% is offset by non-OECD countries.

"We prove a CLT for strategic network formation with homophilous agents. This enables inference on statistics derived from a single large network. We discuss practical procedures."
