Economic growth rates for the period 1968-87 are analyzed for ninety countries. Culture, political, and economic arrangements, and personal freedoms are statistically significant determinants of growth. Personal freedom is shown to be a normal good whose demand might be affected by cultural influences. Democracies raise personal freedoms, ceteris paribus, and, consequently, grow more quickly than nondemocratic regimes. Evidence is found for the convergence hypothesis; other things equal, lower income countries grow more rapidly than higher income countries. Copyright 1995 by Kluwer Academic Publishers
