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...

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...

Explaining cross-border bank expansion in East Africa

Kodongo, Odongo; Natto, Dinah; Biekpe, Nicholas - In: Journal of International Financial Markets, … 36 (2015) C, pp. 71-84

This paper investigates the drivers of bank foreign expansion in East Africa. Our results support the view that institutional quality is vital at the planning phase of banks’ going-abroad decision but its importance is muted once the decision has been taken. Second, relatively competitive...
