The power of sunspots: An experimental analysis

Fehr, Dietmar ; Heinemann, Frank ; Llorente-Saguer, Aniol (2018-08-23)

In an experiment using a coordination game with extrinsic random signals (“sunspots”), we systematically vary the stochastic process generating these signals and measure how signals affect behavior. We find that sunspot equilibria emerge naturally with salient public signals. However, highly correlated private signals can also lead to sunspot-driven behavior, even when this is not an equilibriu...

Experiments in macroeconomics: methods and applications

Cornand, Camille ; Heinemann, Frank (2019-07-26)

This chapter lays out in what ways laboratory experiments can be useful for macroeconomics and discusses some of the methods used in such experiments. Among the main advantages are: bench-testing of alternative policies, capturing strategic uncertainty and biases from standard preferences or Bayesian updating, and accounting for heterogeneity in agents’ expectations and behavior. It is explaine...

Limited higher order beliefs and the welfare effects of public information

Cornand, Camille ; Heinemann, Frank (2015-11-09)

Purpose: In games with strategic complementarities, public information about the state of the world has a larger impact on equilibrium actions than private information of the same precision, because the former is more informative about the likely behavior of others. This may lead to welfare-reducing “overreactions” to public signals as shown by Morris and Shin (2002). Recent experiments on game...

Effect of corruption on perceived difficulties in healthcare access in sub-Saharan Africa

Hsiao, Amber ; Vogt, Verena ; Quentin, Wilm (2019-08-21)

Background Achieving Universal Health Coverage (UHC) by improving financial protection and effective service coverage is target 3.8 of the Sustainable Development Goals. Little is known, however, about the extent to which paying bribes within healthcare acts as a financial barrier to access and, thus, UHC. Methods Using survey data in adults from 32 sub-Saharan African countries in 2014–2015...

Neural mechanisms mediating degrees of strategic uncertainty

Nagel, Rosemarie ; Brovelli, Andrea ; Heinemann, Frank ; Coricelli, Giorgio (2018-01)

In social interactions, strategic uncertainty arises when the outcome of one’s choice depends on the choices of others. An important question is whether strategic uncertainty can be resolved by assessing subjective probabilities to the counterparts’ behavior, as if playing against nature, and thus transforming the strategic interaction into a risky (individual) situation. By means of functional...

Monetary policy obeying the Taylor principle turns prices into strategic substitutes

Cornand, Camille ; Heinemann, Frank (2019-11-01)

Monetary policy affects the degree of strategic complementarity in firms’ pricing decisions if it responds to the aggregate price level. In normal times, when monopolistic competitive firms increase their prices, the central bank raises interest rates, which lowers demand and creates an incentive for firms to reduce their prices. Thereby, monetary policy reduces the degree of strategic compleme...

Multi-mode standardisation: A critical review and a research agenda

Wiegmann, Paul Moritz ; de Vries, Henk J. ; Blind, Knut (2017)

Standardisation is key to shaping new technologies and supporting major ongoing trends, such as the increased importance of platforms, developing ‘smart’ technologies and innovating large-scale complex systems. Standardisation plays a key role in shaping the rules that govern these developments and their effects on society. Due to the large variety of actors involved in these trends, the associ...

The impact of standards and regulation on innovation in uncertain markets

Blind, Knut ; Petersen, Sören S. ; Riillo, Cesare A.F. (2017)

This study analyses the impact of formal standards and regulation on firms’ innovation efficiency, considering different levels of market uncertainty. We argue that formal standards and regulation have different effects, depending on the extent of market uncertainty derived from theoretical considerations about information asymmetry and regulatory capture. Our empirical analysis is based on the...

Interactions among Inter-organizational Measures for Green Supply Chain Management

Kang, Moon Jung ; Hwang, Jongwoon (2017)

Collaboration among supply chain partners is essential to enhance environmental performance during the life cycle of a product. Inter-organizational measures for green supply chain management tend to show diverse patterns because of various requirements that emerge in a complex supply chain. However, this diversity hampers the comprehensive understanding and systematic adoption of these measure...

Lawrenz, Linus ; Xiong, Bobby ; Lorenz, Luise ; Krumm, Alexandra ; Hosenfeld, Hans ; Burandt, Thorsten ; Löffler, Konstantin ; Oei, Pao-Yu ; Hirschhausen, Christian von (2018-11-01)

With an increasing expected energy demand and current dominance of coal electrification, India plays a major role in global carbon policies and the future low-carbon transformation. This paper explores three energy pathways for India until 2050 by applying the linear, cost-minimizing, global energy system model (GENeSYS-MOD). The benchmark scenario “limited emissions only” (LEO) is based on amb...

A Theory of Optimal Green Defaults

Meran, Georg ; Schwarze, Reimund (2018-08-16)

This paper develops an analytical framework for studying the Baumol–Oates efficiency of traditional single instrument abatement policies vis-à-vis green defaults in the face of price inertia and passive choice by subpopulations. In this special case of behavioural heterogeneity, command and control approaches can outperform price-based instruments while pure tax/subsidy schemes need to be adjus...
