<title>Abstract</title> Count data over spatial lattices are the building blocks of spatial econometric data (e.g. unemployment rates in small areas). We consider a hierarchical statistical model made up of a Poisson model for the counts and an underlying Spatial Random Effects process for the logarithm of the...

<title>Abstract</title> Spatial filtering in various forms has become a popular way to address spatial dependence in statistical models (Griffith, 2003; Tiefelsdorf & Griffith, 2007). However, spatial filtering faces computational challenges for large <italic>n</italic> as the current method requires order of n-super-3 operations....

<title>Abstract</title> While much of the literature on cross-section dependence has focused on estimation of the regression coefficients in the underlying model, estimation and inferences on the magnitude and strength of spillovers and interactions has been largely ignored. At the same time, such inferences...

<title>Abstract</title> In this editorial we summarize and comment on papers published in issue 8.1. The first paper is ‘Predation in Space’ by Stefano Colombo. Next comes Arnab Bhattacharjee & Sean Holly's paper entitled ‘Understanding Interactions in Social Networks and Committees’. We then comment...

<title>Abstract</title> Stationarity in space presents two aspects: homogeneity and isotropy. They correspond respectively to stationarity under translations and stationarity under rotations. Testing the hypothesis of isotropy is a common practice in many fields of application of spatial statistics where...

<title>Abstract</title> One of the most widely used tests for spatial dependence is Moran's (1950) I test. The power of the test will depend on the extent to which the spatial-weights matrix employed in computing the Moran I test statistic properly specifies existing interaction links between spatial units....

</title>This paper looks at a little-explored role that universities can play: that of representing a channel for brain gain, enabling regions to attract bright students who may decide to stay after they have graduated. In this way, universities can be a source of selective migration processes and...

<title>Abstract</title> The present paper suggests an estimation procedure for a Cliff and Ord type spatial panel data model with random effects. Building on existing literature, the paper suggests an estimation procedure that (i) considers all the moment conditions in Kapoor et al. (2007) and (ii) allows for...

<title>Abstract</title>This paper presents an empirical framework for analysing spatial wage inequality in Chile. Chile is primarily characterized by two stylized facts: the high spatial concentration around the metropolitan area and the key role of natural resources in the country. The paper considers both...

<title>Abstract</title> In a spatial economic context, we analyse the incentive to prey of an incumbent facing the potential entrance by a rival. We show that the existence of space modifies the incentive to prey of the incumbent and the resulting equilibrium.
