| Summary/Abstract |
In this paper, we use a panel of the 48 contiguous US states over the period 1970-2009 to examine the dynamics of electricity demand in addressing the four hypotheses set forth in the literature: growth, conservation, neutrality, and feedback. In doing so we provide both short-run and long-run elasticity estimates for electricity demand. Recent developments in nonstationary panel estimation techniques allow for heterogeneity in the coefficients while examining the direction of causality among electricity consumption, electricity prices, and income growth. In addition to the full sample, we also disaggregate the sample into three sectors: commercial, industrial, and residential. The short-run results provide evidence in favor of the growth hypothesis for the aggregate sample, as well as for the industrial sector. For the residential and commercial sectors, the conservation hypothesis is supported. Long-run results favor the conservation hypothesis. To ascertain differences in electricity demand relating to electricity intensity we also examine states based on their efficiency in electricity consumption. Overall, the results yield in favor of the growth hypothesis for low intensity states and conservation hypothesis for high intensity states.

| Summary/Abstract |
This paper examines the spatial spillovers of pollution onto the underground economy. The extant literature has considered the pollution-informal economy nexus to some extent, but the spillover effects across national borders have been ignored. Pollution can increase the underground sector when some formal sector production moves to the informal sector (“scale effect”), whereas greater pollution can reduce the underground sector when it invites tougher regulations (“substitution effect”). Results, based on a panel of more than 130 nations and allowing for reverse causality, show both own- and border pollution reduce the underground sector - consistent with the substitution effect. In other results, we find opposite effects of economic and political freedom, and some differences in the influences of specific dimensions of economic freedom and the role of the government. Further, we find that while the size of government increases the underground sector, better institutional quality reduces it. Policy implications of these findings are discussed. The spillovers from neighboring nations are especially relevant for nations that are not islands, which is true for a majority of countries around the world.
