We explore alternative approaches for constructing convex combinations of different types of dependence between observations. ? as well as ? use convex combinations of different connectivity matrices to form a single weight matrix that can be used in conventional spatial regression estimation and inference. An example for the case of two weight matrices, W 1 , W 2 reflecting different types of dependence between a cross-section of regions, firms, individuals etc., located in space would be: W c = γ 1 W 1 + (1 − γ 1)W 2 , 0 ≤ γ 1 ≤ 1. The matrix W c reflects a convex combination of the two weight matrices, with the scalar parameter γ 1 indicating the relative importance assigned to each type of dependence. We explore issues that arise in producing estimates and inferences from these more general cross-sectional regression relationships in a Bayesian framework. We propose two procedures to estimate such models and assess their finite sample properties through Monte Carlo experiments. We illustrate our methodology in an application to CEO salaries for a sample of nursing homes located in Texas. Two types of weights are considered, one reflecting spatial proximity of nursing homes and the other peer group proximity, which arises from the salary benchmarking literature.Lire moins >
