Optimization Over Graphs
Kwon, Suehyun - 2019
This paper defines isomorphism for network formation that is not mathematically isomorphic. Once the pattern of network formation is characterized, one can test for (i) location fixed effects, (ii) heterogeneity, (iii) private information allowing for long-term contracts. The paper provides...

Optimally Controlling an Epidemic
Gonzalez-Eiras, Martín; Niepelt, Dirk - 2021
We propose a flexible model of infectious dynamics with a single endogenous state variable and economic choices. We characterize equilibrium, optimal outcomes, static and dynamic externalities, and prove the following: (i) A lockdown generically is followed by policies to stimulate activity....

Understanding PRC Investment Statistics
Holz, Carsten A. - 2020
Investment statistics of the People's Republic of China are a source of many puzzles. Some investment data are of dubious quality, while the particular concepts of investment and their changing definitions over time are often poorly understood. Fixed asset investment, a remnant of the planned...

The cult of statistical significance
Krämer, Walter - 2010
This article takes issue with a recent book by Ziliak and McCloskey (2008) of the same title. Ziliak and McCloskey argue that statistical significance testing is a barrier rather than a booster for empirical research in many fields and should therefore be abandoned altogether. The present...

Impatience and Uncertainty : Experimental Decisions Predict Adolescents' Field Behavior
Sutter, Matthias - 2011
We study risk attitudes, ambiguity attitudes, and time preferences of 661 children and adolescents, aged ten to eighteen years, in an incentivized experiment and relate experimental choices to field behavior. Experimental measures of impatience are found to be significant predictors of...

Workforce or Workfare?
Brett, Craig - 2011
This article explores the use of workfare as part of an optimal tax mix when labor supply responses are along the extensive margin. Particular attention is paid to the interaction between workfare and an earned income tax credit, two policies that are designed to provide additional incentives...

The (Structural) Gravity of Epidemics
Cuñat, Alejandro - 2020
Epidemiological models assume gravity-like interactions of individuals across space without microfoundations. We combine a simple epidemiological frame-work with a dynamic model of individual location choice. The model predicts that flows of people across space obey a structural gravity...
