Very simple marginal effects in some discrete choice models

Denny, Kevin - 2009

I show a simple back-of-the-envelope method for calculating marginal effects in binary choice and count data models. The approach suggested here focuses attention on marginal effects at different points in the distribution of the dependent variable rather than representative points in the joint...

On the equivalence of location choice models : conditional logit, nested logit and poisson

Schmidheiny, Kurt; Brülhart, Marius - 2009

It is well understood that the two most popular empirical models of location choice - conditional logit and Poisson - return identical coefficient estimates when the regressors are not individual specific. We show that these two models differ starkly in terms of their implied predictions. The...

. Equations (4) and (5) together establish the Poisson regression model ( 500 | ) exp( ) ii i i ETOP λ ′= =xxβ (6) The Poisson … regression model has a number of merits: it captures the discrete and non- negative nature of the data; it allows inference to be … to the actual sum. Assuming independence among the count variables, the log-likelihood for the Poisson regression model …

How Low Business Tax Rates Attract Multinational Headquarters : Municipality-Level Evidence from Germany

Becker, Sascha O. - 2009

Most existing empirical evidence on the impact of profit taxation on multinational firm activity is based on cross-country data. One major drawback of such data is that countries differ not only with regard to taxes but along other dimensions which might be hard to capture by means of observable...

Fixed and Random Effects Models for Count Data

Greene, William - 2009

The most familiar fixed effects (FE) and random effects (RE) panel data treatments for count data were proposed by Hausman, Hall and Griliches (HHG) (1984). The Poisson FE model is particularly simple and is one of a small few known models in which the incidental parameters problem is, in fact,...

Functional Form and Heterogeneity in Models for Count Data

Greene, William - 2009

This study presents several extensions of the most familiar models for count data, the Poisson and negative binomial models. We develop an encompassing model for two well known variants of the negative binomial model (the NB1 and NB2 forms). We then propose some alternative approaches to the...
