AIRWAYS TUNNEL THROUGH THE ECONOMIC RECESSION<br />

APPENDIX FIGURE 9.2 In a simplified presentation of Figure 9.2 we have added here examples of the rare “tunneling through”<br />

process that continues growing unaffected beyond the period of recession. On the first wave it was canal construction in Russia<br />

that continued growing. On the present wave, besides the airways shown, also computer innovation, natural gas pipelines, nuclear<br />

power stations, and pollution abatement tunnel through. The figure is adapted from Figure 9.2 in the text. ∗<br />

∗ The data come mostly from Arnulf Grubler, The Rise and Fall of Transport Infrastructures, (Heidelberg: Physica-Verlag, 1990).<br />
