Does Socialized Ownership of Resources lead to Laxer Environmental Rules?  A Wall Street Journal columnist notes that Brazil is much more open to offshore oil drilling than is the US.  Is it because in Brazil profits from drilling go to the government and in the US profits go to private companies?

TV and Fertility Rates.  Here's a suggestion that we could lower fertility rates by subsidizing access to television, especially soap operas

"We focus on fertility choices in Brazil, a country where soap operas (novelas) portray families that are much smaller than in reality. We exploit differences in the timing of entry into different markets of Rede Globo, the network that has an effective monopoly on novelas production in this country. Using Census data for the period 1970-1991, we find that women living in areas covered by the Globo signal have significantly lower fertility. The effect is strongest for women of lower socioeconomic status and for women in the central and late phases of their fertility cycle, consistent with stopping behavior. The result is robust to placebo treatments and does not appear to be driven by selection in Globo entry."
