On the Perils of Stabilizing Prices When Agents are Learning.

We show that price level stabilization is not optimal in an economy where agents have incomplete knowledge about the policy implemented and try to learn it. A systematically more accommodative policy than what agents expect generates short term gains without triggering an abrupt loss of con- fidence, since agents update expectations sluggishly. In the long run agents learn the policy implemented, and the economy converges to a rational expectations equilibrium in which policy does not stabilize prices, economic volatility is high, and agents suffer the corresponding welfare losses. However, these losses are outweighed by short term gains from the learning phase

Adam Smith and Modern Economics.

In his Wealth of Nations (1776) Adam Smith created an agenda for the study of the economy that is reflected in the structure of modern economics. This paper describes Smith’s contributions to four central areas of economic theory: The theory of price formation, the relationship between market outcomes and the public interest, the role of the state in the economy, and the sources of economic growth. In each case, an attempt is made to relate Smith’s contribution to the state of contemporary economics, showing both the similarities and contrasts between the respective approaches

Challenges for the construction of historical price indices : the case of Norway, 1777-1920

This paper reviews some methodological and practical problems encountered in the construction of historical price indices. The underlying data sets in such studies are often characterized by heterogenous and incomplete price series. It is shown that by using the repeat sales method for constructing the subindices for individual commodity groups some of the main problems can be overcome. The procedures are illustrated by material from the construction of monthly price indices for Norway from the year 1777 to 1920. The price indices shed new light on two great wartime in ationary episodes in Norway: 1807-1817 and 1913-1920. In spite of a 61-fold increase in the price level in the rst period and a 4-fold increase in the second, it is found that, after in ation had been brought under control, prices reverted to a level consistent with the purchasing power parity principle
