<Para ID="Par1">Different fundamental methodological spatial econometric issues are discussed not yet addressed by the existent empirical literature on FDI and third country effects that explains why it has failed to find results consistent with formal theory. This is demonstrated by taking the baseline spatial...</para>

Higher-order spatial econometric models that include more than one weights matrix have seen increasing use in the spatial econometrics literature. There are two distinct issues related to the specification of these extended models. The first issue is what form the higher-order spatial...

This paper tests the feasibility and empirical implications of a spatial econometric model with a full set of interaction effects and weight matrix defined as an equally weighted group interaction matrix applied to research productivity of individuals. We also elaborate two extensions of this...
