We use aggregate GDP data and within-country income shares for the period 1970-1998 to assign a level of income to each person in the world. We then estimate the gaussian kernel density function for the worldwide distribution of income. We compute world poverty rates by integrating the density...

We revisit Western Europe's record with labor-productivity convergence, and tentatively extrapolate its implications for the future path of Eastern Europe. The poorer Western European countries caught up with the richer ones through both higher rates of physical capital accumulation and greater...

This paper investigates the use of high-frequency scanner data to construct price indexes. In the presence of inventory behavior, purchases and consumption by individuals differ over time. Cost-of-living indexes can still be constructed using data on purchases. For weekly data on canned tuna,...

What mental models do individuals use to approximate their tax schedule? Using an incentivized income-tax forecasting task, we estimate the prevalence of the "schmeduling" heuristics for constructing mental representations of nonlinear incentive schemes. We find evidence of widespread adoption...

State business climate indexes capture state policies that might affect economic growth. State rankings in these indexes vary wildly, raising questions about what the indexes measure and which policies are important for growth. Indexes focused on productivity do not predict economic growth,...
