Wanna Get Away? RD Identification Away from the Cutoff
Angrist, Joshua; Rokkanen, Miikka - National Bureau of Economic Research (NBER) - 2012
also of interest, but identification of such effects requires stronger assumptions than are required for identification at … the cutoff. This paper discusses RD identification away from the cutoff. Our identification strategy exploits the … variable is assumed to be ignorable. This identification strategy is illustrated with data on applicants to Boston exam schools …

IV Quantile Regression for Group-level Treatments, with an Application to the Distributional Effects of Trade
Chetverikov, Denis; Larsen, Bradley; Palmer, Christopher - National Bureau of Economic Research (NBER) - 2015
We present a methodology for estimating the distributional effects of an endogenous treatment that varies at the group level when there are group-level unobservables, a quantile extension of Hausman and Taylor (1981). Because of the presence of group-level unobservables, standard quantile...

Charters Without Lotteries: Testing Takeovers in New Orleans and Boston
Angrist, Joshua; Abdulkadiroğlu, Atila; Hull, Peter D.; … - National Bureau of Economic Research (NBER) - 2014
Lottery estimates suggest oversubscribed urban charter schools boost student achievement markedly. But these estimates needn’t capture treatment effects for students who haven’t applied to charter schools or for students attending charters for which demand is weak. This paper reports...

Identification and Inference with Many Invalid Instruments
Chetty, Raj; Glaeser, Edward Ludwig; Imbens, Guido; … - National Bureau of Economic Research (NBER) - 2011
consider restrictions on these direct effects that allow for point identification of the effect of interest. The setup leads to … new insights concerning the properties of conventional estimators, novel identification strategies, and new estimators to … exploit those strategies. A key assumption underlying the main identification strategy is that the product of the direct …

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...

The Roles of Cognitive and Non-Cognitive Skills in Moderating the Effects of Mixed-Ability Schools on Long-Term Health
Basu, Anirban; Jones, Andrew M.; Dias, Pedro Rosa - National Bureau of Economic Research (NBER) - 2014
We examine heterogeneity in the impacts of exposure to mixed-ability ‘comprehensive’ schools in adolescence on long-term health and smoking behaviour. We explore the roles that cognitive and non-cognitive skills may play in moderating these impacts. We use data from the 1958 National Child...

Estimating Person-Centered Treatment (PeT) Effects Using Instrumental Variables
Basu, Anirban - National Bureau of Economic Research (NBER) - 2012
This paper builds on the methods of local instrumental variables developed by Heckman and Vytlacil (1999, 2001, 2005) to estimate person-centered treatment (PeT) effects that are conditioned on the person's observed characteristics and averaged over the potential conditional distribution of...

Instrumental Variables Methods in Experimental Criminological Research: What, Why, and How?
Angrist, Joshua - National Bureau of Economic Research (NBER) - 2005
Quantitative criminology focuses on straightforward causal questions that are ideally addressed with randomized experiments. In practice, however, traditional randomized trials are difficult to implement in the untidy world of criminal justice. Even when randomized trials are implemented, not...

Economics, History, and Causation
Morck, Randall; Yeung, Bernard - National Bureau of Economic Research (NBER) - 2011
Economics and history both strive to understand causation: economics using instrumental variables econometrics and history by weighing the plausibility of alternative narratives. Instrumental variables can lose value with repeated use because of an econometric tragedy of the commons bias: each...
