Martin Feldstein:1 Chairman Alan Greenspan's remarks today give us an opportunity to understand his thinking about monetary policy and about the Federal Reserve's actions during the past 15 years. It was a period of substantial accomplishment that no doubt reflects in considerable measure the views of the Chairman himself. The Fed's primary goal, price stability, has been achieved, with inflation down from 4 percent at the end of the 1980's to about 1.5 percent now. The 2-percentage-point difference between the interest rate on conventional Treasury bonds and on inflation-indexed bonds (TIPS) shows that financial markets expect inflation will remain at about 2 percent for at least the next decade.

The role of technology in the transition from premodem, Malthusian to modem economies in late 18thand 19th-century Europe is among the major questions in economic history, but it is still poorly understood. In particular, the view that premodern societies experienced low labor productivity and stagnant living standards, and that technological change before ca. 1800 was close to zero due to pervasive guild rent-seeking and poorly specified property rights to knowledge (Douglass C. North, 1981; Joel Mokyr, 2002), is hard to square with the fact that the surge of technological innovation in the 18th century occurred within institutional frameworks not too dissimilar to those of 1300

Economists have invested a great deal of effort in trying to understand the motivation for family transfers, yet recent empirical work testing the seemingly appealing models of altruism and exchange has led to decidedly mixed results. A major stumbling block has been the lack of adequate data. We take a fresh look at the issue using responses to an innovative survey question that directly asks mother about the planned division of their estates. We find that both altruism and exchange are frequently offered as explanations of behavior and are of nearly equal importance. Furthermore, the explanations are consistent with observable characteristics of the mother, lending support to the validity of the question. We also find that among step or adopted families, genetic ties play an important role. Because motivating factors appear to differ across families the lack of a consensus among previous researchers about motives ought not to be surprising
