The article argues that Marxist economic theory, in conjunction with information technology, provides the basis on which a viable socialist economic program can be advanced, and that the development of computer technology and the Internet makes economic planning possible. In addition, it argues that the socialist movement has never developed a correct constitutional program, and that modern technology opens up opportunities for democracy. Finally, it reviews the Austrian arguments against the possibility of socialist calculation in the light of modern computational capacity and the constraints of the Kyoto Protocol. http://socialsciences.scielo.org/scielo.php?script=sci_arttext&pid=S0124-59962008000100002&lng=es&nrm=iso&tlng=es Does the lack of international copyrights benefit or harm developing countries? This article examines the effects of U.S. copyright piracy during a period when the U.S. was a developing country. U.S. statutes protected the copyrights of American citizens from 1790, but until 1891 deemed the works of foreign citizens to be in the public domain. In 1891, the laws were changed to allow foreigners to obtain copyright protection in the United States if certain conditions were met. Thus, this episode in American history provides us with a convenient way of investigating the consequences of international copyright piracy. The analysis is based on copyright registrations, information on authors, book titles and prices, financial data from the accounts of a major publishing company, and lawsuits regarding copyright questions to investigate the welfare effects of widespread infringement of foreign works on American publishers, writers, and the public. The results suggest that the United States benefited from piracy and that the choice of copyright regime was endogenous to the level of economic development.
