This article examines the determinants of local tax rates. For the two main local taxes in Spain—the property tax and the motor vehicle tax—we test the existence of tax mimicking, yardstick competition, and political trends in a sample of 2,713 municipalities. Using various spatial models, the results support the hypothesis of tax mimicking, with coefficients above 0.40. We also show the relevance of political variables such as the ideology of incumbents and political fragmentation. The fact that incumbents with weaker political support exhibit stronger mimicking behavior is interpreted as evidence in favor of yardstick competition. Finally, we find that incumbents mimic neighboring municipalities ruled by the same political party, confirming the political trends hypothesis. (JEL C31, H71, H77)

Self-employment is usually associated with entrepreneurship and it is often promoted as a way of reducing unemployment. Our aim in this article is to analyse the relationship between self-employment and unemployment taking into account its spatial dimension. The entrepreneur activity in each region depends not only on its own endowment but the entrepreneurship environment may be exerted some influence. Regional Spanish data are used to obtain evidence about this relationship using a Spatial Durbin model to embed the spatial dimension. The results reveal that both the direct and indirect effects are relatively small. Further, if unemployment increases in a region, self-employment decreases. However, if unemployment grows in neighbouring regions, incentives for entering self-employment increase, implying that there is a ‘refugee’ effect (self-employment as an answer to the lack of wage employment).
