Hillary Term 2023 — Talks & Materials

19/01 — De-escalation Technology: The Impact of Body-worn Cameras on Citizen-Police Interactions

By Daniel AC Barbosa (joint with Thiemo Fetzer, Caterina Soto-Vieira and Pedro CL Souza)

Broad Topic: Applied Microeconomics. Specific Topic: Economics of Crime, Policy Evaluation, RCT.

Abstract

We provide experimental evidence that monitoring of the police activity through body-worn cameras reduces use-of-force, handcuffs and arrests, and enhances criminal reporting by the police. Stronger treatment effects occur on events ex-ante classified as low risk. Monitoring effects are moderated by officer rank, consistent with a career concern motive by junior officers. Our results stand in sharp contrast with previous literature which, due to often used coarser designs, showed muted or null body-worn camera effects on use of force. We show that these designs are likely to suffer from attenuation biases. Overall, our results show that body-worn cameras robustly de-escalate citizen-police interactions.

26/01 — Germany's 9-Euro Ticket: A Short Term Price Shock with Lasting Effects?

By Milan Marcus

Broad Topic: Applied Microeconomics, Urban Economics. Specific Topic: Transportation Economics.

Abstract

In response to the increased cost of living following the Russian invasion of Ukraine, Germany introduced a temporary cheap nationwide transport ticket (June–Aug 2022). This paper establishes that lower fares increased ridership and reduced car traffic, then asks if the short-term shock produced persistent changes in behaviour. Using air pollution, peak-hour traffic and transit ridership from 30+ German cities, the paper investigates whether some motorists continued using public transport after fares returned to normal.

02/02 — The East Asian Miracle: Did Industrial Policy Transform Growth Trajectories

By Kristen Yang

Broad Topic: Development Economics. Specific Topic: Industrial Policy.

Abstract

The talk compares the effects of industrial policy across East Asian countries using staggered diff-in-diff and counterfactual methods, assessing whether temporary or persistent policy differences explain divergent growth trajectories.

09/02 — Communication with Cultural Agents

By Brooklyn Han

Broad Topic: Applied Microeconomic Theory. Specific Topic: Information Design, Coordination Games, Economics of Culture.

Abstract

Using an information design approach, the paper investigates optimal government communication in societies with cultural heterogeneity that affects equilibrium selection in coordination games. Results highlight how cultural strength and diversity shape the optimal communication policy, with applications to policymaking during crises and cross-country differences in public messaging.

15/02 — The Effects of Economic Information on Household Expectations and Economic Literacy

By Peter Rickards

Broad Topic: Applied Macroeconomics, Experimental Economics. Specific Topic: Economic Expectations, Information Effects, Economic Literacy.

Abstract

This paper uses an RCT to investigate the impact of informational treatments on household expectations and economic literacy in Australia.

22/02 — Modeling Time Inconsistency through Non-stationary Instantaneous Utility

By Stefania Merone

Broad Topic: Microeconomic Theory, Behavioral Economics. Specific Topic: Choice under Uncertainty.

Abstract

The paper proposes a framework to model time-inconsistency by deviating minimally from the discounted utility assumption through non-stationary instantaneous utility, producing testable implications on intertemporal choice.

08/03 — Controlled Foreign Corporation Rules under Heterogeneous Home Country Taxation

By Gerwin Kiessling

Broad Topic: Public Economics. Specific Topic: International Corporate Taxation.

Abstract

This paper examines how CFC rules affect multinationals' financial decisions when home-country corporate tax rates vary (using German municipality variation and administrative foreign investment panels).
