Interpreting Ols Estimands When Treatment Effects are Heterogeneous : Smaller Groups Get Larger Weights

Słoczyński, Tymon - 2020

Applied work often studies the effect of a binary variable ("treatment") using linear models with additive effects. I study the interpretation of the OLS estimands in such models when treatment effects are heterogeneous. I show that the treatment coefficient is a convex combination of two...

Modelling Volatilities and Conditional Correlations in Futures Markets with a Multivariate T Distribution

Pesaran, Bahram; Pesaran, M. Hashem - 2021

This paper considers a multivariate t version of the Gaussian dynamic conditional correlation (DCC) model proposed by Engle (2002), and suggests the use of devolatized returns computed as returns standardized by realized volatilities rather than by GARCH type volatility estimates. The t-DCC...

The Effects of Test-Based Retention on Student Outcomes Over Time : Regression Discontinuity Evidence from Florida

Schwerdt, Guido - 2013

A growing number of American states require that students who do not demonstrate basic reading proficiency at the end of third grade be retained and provided with remedial services. We exploit a discontinuity in the probability of third grade retention under Florida's test-based promotion policy...

Does it Pay to Work for Free? Wage Returns and Gender Differences in the Market for Volunteers

Cozzi, Guido - 2013

Working as a volunteer is a widespread phenomenon that has both individual and societal benefits. In this paper, we identify the wage returns to working for free by exploiting exogenous variation in rainfall across local area districts in England, Scotland and Wales. Instrumental variables...

On the Estimation of Treatment Effects with Endogenous Misreporting

Nguimkeu, Pierre - 2018

Participation in social programs is often misreported in survey data, complicating the estimation of the effects of those programs. In this paper, we propose a model to estimate treatment effects under endogenous participation and endogenous misreporting. We show that failure to account for...

Difference‐In‐Difference Estimation by FE and OLS When There is Panel Non‐Response

Lechner, Michael - 2015

We show that the OLS and fixed‐effects (FE) estimators of the popular difference-in-differences model may deviate when there is time varying panel non-response. If such non-response does not affect the common-trend assumption, then OLS and FE are consistent, but OLS is more precise. However,...

Two-Stage Least Squares Random Forests with an Application to Angrist and Evans (1998)

Biewen, Martin - 2020

We develop the case of two-stage least squares estimation (2SLS) in the general framework of Athey et al. (Generalized Random Forests, Annals of Statistics, Vol. 47, 2019) and provide a software implementation for R and C++. We use the method to revisit the classic application of instrumental...

The Effects of Work-Life Benefits on Employment Outcomes in Canada : A Multivariate Analysis

Fang, Tony - 2019

work-life benefits and various employment outcomes in the Canadian labour market. Whilst the theory of compensating wage … differentials hypothesizes an inevitable trade-off between higher wages and non-wage benefits, the efficiency wage theory suggests … otherwise. The empirical evidence broadly supports the efficiency wage theory, thus rejecting the compensating wage …

The Last Refuge of a Scoundrel? Patriotism and Tax Compliance

Konrad, Kai A. - 2009

We study the effects of patriotism on tax compliance. In particular, we assume that individuals feel a (random draw of) warm glow from honestly paying their taxes. A higher expected warm glow reduces the government's optimal audit probability and yields higher tax compliance. Second, individuals...

On the Multivariate Analysis of the Lisbon Process

Tausch, Arno - 2007

Starting from Professor Kornai's assertion about the necessity to focus on the long-term perspectives of the transformation process, we analyze in this paper the Lisbon performance of the countries of the European Union from such a long-term, structural perspective. We present in a simple form...
