This paper investigates the differences between directly and indirectly seasonally adjusted aggregates. This difference is derived analytically for linear seasonal adjustment methods. GDP data for five European countries and three classes of seasonal adjustment methods are used to show...

A utilitarian measure of economic growth combines changes in the distribution of income with changes in real income per person to show how much better off people are becoming over time. It is the rate of growth of the dollar value of average utility of income. As such , it is seen differently by...

We examine economic activity in a large virtual economy which was designed to allow decentralized barter as the sole exchange institution. We find that a small subset of goods emerges endogenously which act of media of exchange. Our analysis includes estimation of spot exchange rates between...

In this paper we study the dynamics of economic growth for 140 countries during the period 1951-2003. The variables representing economic performance are levels and growth rates of per capita GDP. Using the concept of economic regime, we introduce a notion of distance between the dynamical paths...

I study the manipulation of GDP growth statistics in non-democracies by comparing the self-reported GDP figures to the nighttime lights recorded by satellites from outer space. I show that the night-lights elasticity of GDP is systematically larger in more authoritarian regimes. This autocracy...

Measurement quality is a fundamental factor in determining the cost of transactions within organizations and markets. A huge gulf separates the meaningfulness and precision of business metrics as currently achieved from the quality that has been routinely obtained for decades in research and in...

I study the overstatement of GDP growth in autocratic regimes by comparing the self-reported GDP figures to the night time lights (NTL) recorded by satellites from outer space. I show that the NTL elasticity of GDP is systematically larger in more authoritarian regimes. This autocracy gradient...
