Finite sample evaluation of causal machine learning methods : guidelines for the applied researcher

Naghi, Andrea A.; Wirths, Christian P. - 2021

The econometrics literature proposed several new causal machine learning methods (CML) in the past few years. These methods harness the strength of machine learning methods to flexibly model the relationship between the treatment, outcome and confounders, while providing valid inferential...

Assessing autonomous algorithmic collusion : Q-learning under short-run price commitments

Klein, Timo - 2018 - Revision: September 2018

A novel debate within competition policy and regulation circles is whether autonomous machine learning algorithms may learn to collude on prices. We show that when fims face short-run price commitments, independent Q-learning (a simple but well-established self-learning algorithm) learns to...

Data science in strategy : machine learning and text analysis in the study of firm growth

Kolkman, Daan; Witteloostuijn, Arjen van - 2019

This study examines the applicability of modern Data Science techniques in the domain of Strategy. We apply novel techniques from the field of machine learning and text analysis. We proceed in two steps. First, we compare different machine learning techniques to traditional regression methods in...

Fuzzy firm name matching : merging Amadeus firm data to PATSTAT

Bremer, Leon - 2023

When merging firms across large databases in the absence of common identifiers, text algorithms can help. I propose a high-performance fuzzy firm name matching algorithm that uses existing computational methods and works even under hardware restrictions. The algorithm consists of four steps,...

Periodic unobserved cycles in seasonal time series with an application to US unemployment

Koopman, Siem Jan; Ooms, Marius; Hindrayanto, Irma - 2006

This paper discusses identification, specification, estimation and forecasting for a general class of periodic unobserved components time series models with stochastic trend, seasonal and cycle components. Convenient state space formulations are introduced for exact maximum likelihood...

The wage penalty of dialect-speaking

Ours, Jan C. van; Yao, Yuxin - 2016

Our paper studies the effects of dialect-speaking on job characteristics of Dutch workers, in particular on their hourly wages. The unconditional difference in median hourly wages between standard Dutch speakers and dialect speakers is about 10.6% for males and 6.7% for females. If we take into...

Digital infrastructure and physical proximity

Tranos, Emmanouil; Nijkamp, Peter - 2013

Some 2000 years ago, the average annual distance a person would normally travel, was approximately 500 km. The action radius of most people remained rather stable, but it rose gradually after the industrial revolution to some 1820 km (by car, bus, railway or aircraft) in the year 1960. Then, a...

Diffusion of behavior in network games orchestrated by social learning

Huang, Jiaping; Koster, Maurice; Lindner, Ines - 2013

The novelty of our model is to combine models of collective action on networks with models of social learning. Agents are connected according to an undirected graph, the social network, and have the choice between two actions: either to adopt a new behavior or technology or stay with the default...
