The Perils of Peer Effects
Angrist, Joshua - National Bureau of Economic Research (NBER) - 2013
Individual outcomes are highly correlated with group average outcomes, a fact often interpreted as a causal peer effect. Without covariates, however, outcome-on-outcome peer effects are vacuous, either unity or, if the average is defined as leave-out, determined by a generic intraclass...

Identification of Local Treatment Effects Using a Proxy for an Instrument
Chalak, Karim - Department of Economics, Boston College - 2010
The method of indirect least squares (ILS) using a proxy for a discrete instrument is shown to identify a weighted average of local treatment effects. The weights are nonnegative if and only if the proxy is intensity preserving for the instrument. A similar result holds for instrumental...

From Correlation to Granger Causality
Stern, David I. - Crawford School of Public Policy, Australian National … - 2011
analysis cannot establish causality in the absence of a priori theory on possible causal mechanisms or controlled and … randomized experiments. However, two regression based econometric techniques - instrumental variables and Granger causality - can … be used to test for causality given some assumptions. The Granger causality technique is applied to a time series data …

Identification of Average Random Coefficients under Magnitude and Sign Restrictions on Confounding
Chalak, Karim - Department of Economics, Boston College - 2012
This paper studies measuring the average effects of X on Y in a structural system with random coefficients and confounding. We do not require (conditionally) exogenous regressors or instruments. Using proxies W for the confounders U, we ask how do the average direct effects of U on Y compare in...

Voluntary work and wages
Bruno, Bruna; Fiorillo, Damiano - Economics and Econometrics Research Institute (EERI) - 2014
The effects of voluntary work on earnings have recently been studied for some developed countries such as Canada, France and Austria. This paper extends this line of research to Italy, using data from the European Union Statistics on Income and Living Conditions (EU-SILC) dataset. A double...

OLS and IV estimation of regression models including endogenous interaction terms
Bun, Maurice; Harrison, Teresa D - LeBow College of Business, Drexel University - 2014
We analyze a class of linear regression models including interactions of endogenous regressors and exogenous covariates. We show that, under typical conditions regarding higher-order dependencies between endogenous and exogenous regressors, the OLS estimator of the coefficient of the interaction...

Nonparametric Identification in Structural Economic Models
Matzkin, Rosa L. - In: Annual Review of Economics 5 (2013) 1, pp. 457-486
Structural economic models allow one to analyze counterfactuals when economic systems change and to evaluate the well-being of economic agents. A key element in such analysis is the ability to identify the primitive functions and distributions of the economic models that are employed to describe...

The Long-Run Effects of Attending an Elite School: Evidence from the UK
Clark, Damon; Del Bono, Emilia - Institute for the Study of Labor (IZA) - 2014
This paper estimates the impact of elite school attendance on long-run outcomes including completed education, income and fertility. Our data consists of individuals born in the 1950s and educated in a UK district that assigned students to either elite or non-elite secondary schools. Using...

Voluntary work and labour income
Bruno, Bruna; Fiorillo, Damiano - Volkswirtschaftliche Fakultät, … - 2013
The paper studies the effect of voluntary work on labour income for Italian employees. The Heckman and Instrumental Variables methods are used in order to control for self-selection bias of participation in labour market and endogeneity of volunteering. The results show that a wage premium of 3...
