Abstract: This paper analyzes the properties of a frequently-used test of spatial spillover effects of public capital when using regional panel data. This test compares the estimates of the coefficients of public capital in two different production functions. The benchmark model includes the public capital of each region as an explanatory variable. In the second model the public capital of each region is augmented with public capital in neighbouring regions. Using basic regression algebra, we show that the results of this “pseudo-test” are not necessarily related to the existence of spillover effects.
