In 1935 Franklin Roosevelt established the Rural Electrification Administration, and launched a large-scale initiative to bring electricity to what was then the Great Dust Bowl. This Act facilitated millions of dollars worth of loans to private, public and small cooperative utility ventures. Some of these new power companies paid folk singers to roam the Western United States and write songs which would promote rural electrification. The resulting Woody Guthrie song Grand Coulee Dam (1941) is perhaps the most specific about the positive effects of electrification on labour markets: “Now in Washington and Oregon you can hear the factories hum, Making chrome and making manganese and light aluminum.”. Guthrie, neither environmentalist nor economist, was one of many who believed that electrification would bring jobs and economic diversification, and have positive impacts on the rural standard of living.
Folk wisdom aside, a large literature now examines the effects of post-war technological changes on the US labour market. Rising US female labour force participation is attributed to technological improvements, and particularly to technologies that relaxed the time constraints from childbearing (see, for example Angrist and Evans (1998), Goldin and Katz (2002), Greenwood, Seshadri, and Vandenbrouke (2005), and Bailey (2006)). A major explanation of rising wage inequality in the US since the 1980s is that technological changes have been disproportionally beneficial to high-skilled workers (Acemoglu (1998), Acemoglu (2002), and Galor and Moav (2006)). Surprisingly, despite this extensive literature on the labour market effects of technological change, there is still very little work relating rural electrification to subsequent changes in the structure of the US labour market.
