Spatial Errors in Count Data Regressions

Moser, Petra; Bertanha, Marinho - National Bureau of Economic Research (NBER) - 2014

Count data regressions are an important tool for empirical analyses ranging from analyses of patent counts to measures of health and unemployment. Along with negative binomial, Poisson panel regressions are a preferred method of analysis because the Poisson conditional fixed effects maximum...

Growth, Reform Indicators and Policy Complementaries

Braga de Macedo, Jorge A.; Oliveira Martins, Joaquim - National Bureau of Economic Research (NBER) - 2006

This paper discusses the design of structural policies by relating second-best results and the complementarity of reforms. It computes a complementarity index based on structural reform indicators compiled by the EBRD for transition countries, assuming that the run-up to EU integration...

Dynamic Cost-offsets of Prescription Drug Expenditures: Panel Data Analysis Using a Copula-based Hurdle Model

Deb, Partha; Trivedi, Pravin K.; Zimmer, David M. - National Bureau of Economic Research (NBER) - 2009

This paper presents a new multivariate copula-based modeling approach for analyzing cost-offsets between drug and nondrug expenditures. Estimates are based on panel data from the Medical Expenditure Panel Survey (MEPS) with quarterly measures of medical expenditures. The approach allows for...

Rule of Law, Democracy, Openness, and Income: Estimating the Interrelationships

Rigobon, Roberto; Rodrik, Dani - National Bureau of Economic Research (NBER) - 2004

We estimate the interrelationships among economic institutions, political institutions, openness, and income levels, using identification through heteroskedasticity (IH). We split our cross-national dataset into two sub-samples: (i) colonies versus non-colonies; and (ii) continents aligned on an...

"Healthy, Wealthy and Wise?" Revisited: An Analysis of the Causal Pathways from Socio-economic Status to Health

Winter, Joachim; Stowasser, Till; Heiss, Florian; … - National Bureau of Economic Research (NBER) - 2011

Much has been said about the stylized fact that the economically successful are not only wealthier but also healthier than the less affluent. There is little doubt about the existence of this socio-economic gradient in health, but there remains a vivid debate about its source. In this paper, we...

Dynamic Models of R&D, Innovation and Productivity: Panel Data Evidence for Dutch and French Manufacturing

MAIRESSE, Jacques; Mohnen, Pierre; Raymond, Wladimir; … - National Bureau of Economic Research (NBER) - 2013

This paper introduces dynamics in the R&D to innovation and innovation to productivity relationships, which have mostly … individual effects and idiosyncratic errors correlated across equations and that differ in the way innovation enters the … Community Innovation Survey. The results provide evidence of robust unidirectional causality from innovation to productivity and …

Using Genetic Lotteries within Families to Examine the Causal Impact of Poor Health on Academic Achievement

Lehrer, Steven; Fletcher, Jason M. - National Bureau of Economic Research (NBER) - 2009

While there is a well-established, large positive correlation between mental and physical health and education outcomes, establishing a causal link remains a substantial challenge. Building on findings from the biomedical literature, we exploit specific differences in the genetic code between...

Empirical Asset Pricing and Statistical Power in the Presence of Weak Risk Factors

Burnside, A. Craig - National Bureau of Economic Research (NBER) - 2007

The risk factors in many consumption-based asset pricing models display statistically weak correlation with the returns being priced. Some GMM-based procedures used to test these models have very low power to reject proposed stochastic discount factors (SDFs) when they are misspecified and the...

Identification with Imperfect Instruments

Nevo, Aviv; Rosen, Adam Michael - National Bureau of Economic Research (NBER) - 2008

Dealing with endogenous regressors is a central challenge of applied research. The standard solution is to use instrumental variables that are assumed to be uncorrelated with unobservables. We instead assume (i) the correlation between the instrument and the error term has the same sign as the...

Panel Data Estimators for Nonseparable Models with Endogenous Regressors

Altonji, Joseph G.; Matzkin, Rosa Liliana - National Bureau of Economic Research (NBER) - 2001

We propose two new estimators for a wide class of panel data models with nonseparable error terms and endogenous explanatory variables. The first estimator covers qualitative choice models and both estimators cover models with continuous dependent variables. The first estimator requires the...
