The Finite Sample Performance of Inference Methods for Propensity Score Matching and Weighting Estimators

Bodory, Hugo ; Camponovo, Lorenzo ; Huber, Martin ; Lechner, Michael

In: Journal of Business and Economic Statistics, 2020, vol. 38, no. 1, p. 183-200

This article investigates the finite sample properties of a range of inference methods for propensity score-based matching and weighting estimators frequently applied to evaluate the average treatment effect on the treated. We analyze both asymptotic approximations and bootstrap methods for computing variances and confidence intervals in our simulation designs, which are based on German...

Correlations in multithermostat Brownian systems with Lorentz force

Abdoli, Iman ; Kalz, Erik ; Vuijk, Hidde D. ; Wittmann, René ; Sommer, Jens-Uwe ; Brader, Joseph M. ; Sharma, Abhinav

In: New Journal of Physics, 2020, vol. 22, no. 9, p. 093057

We study the motion of a Brownian particle subjected to Lorentz force due to an external magnetic field. Each spatial degree of freedom of the particle is coupled to a different thermostat. We show that the magnetic field results in correlation between different velocity components in the stationary state. Integrating the velocity autocorrelation matrix, we obtain the diffusion matrix that...

Institutional setting and networks effect on international trade : Three essays on international trade

Arioldi, Davide ; Maggi, Rico (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2018 ; 2018ECO016.

This thesis explores the role of different measures of proximity on some topics related to international trade. We focus on how institutional setting (institutional proximity) and network structure (cognitive and social proximity) influence the geography of international trade. In the first chapter, we extend the results of Rose and Spiegel (2011) and the findings by Bista (2017) proposing a...
