We assemble a new global database on motor vehicle travel speed in over 1,200 large cities in 152 countries. We then estimate comparable city-level indices of travel speed and congestion. Most of the variation in urban travel speed is across countries, not within. National income per capita...

This paper describes a new, industry-adjusted index of state environmental compliance costs from 1977 to 1994. The index has two principal advantages: it controls for states' industrial compositions, and it can be calculated for 17 years, thus facilitating comparisons both among states and...

Many questions about technology growth and development in health care call for a broad-based characterization of technology availability. In this paper, we explore the possibility of producing aggregated estimates of technology availability by constructing an index of technology availability in...

This paper develops and characterizes an index of trade policy restrictiveness defined as the uniform tariff equivalent which maintains the same volume of trade as a given set of tariffs, quota, and domestic taxes and subsidies. We relate this volume-equivalent index to the Trade Restrictiveness...

We review in considerable detail the conceptual and measurement issues that underlie construction of medical care price indexes in the U.S., particularly the medical care consumer price indexes (MCPIs) and medical-related producer price indexes (MPPIs). We outline salient features of the medical...

Although broad trends in medical spending in the U.S. over the last decade have received widespread attention from policymakers, very little attention has focused on the components of those changes. For many other industries, economists typically divide nominal expenditures by an official...

This paper develops an interpretation of the Asian meltdown focused on moral hazard as the common source of overinvestment, excessive external borrowing, and current account deficits. To the extent that foreign creditors are willing to lend to domestic agents against future bail-out revenue from...

This paper considers forecasting a single time series using more predictors than there are time series observations. The approach is to construct a relatively few indexes, akin to diffusion indexes, which are weighted averages of the predictors, using an approximate dynamic factor model....

In recent papers, Nelson and Pack (1995) , Rodrik (1997), and Hsieh (1997a) argue that standard measures of total factor productivity growth in countries where the capital-labour ratio has risen rapidly, e.g. the East Asian NICS, will understate true productivity growth if the elasticity of...

This paper rehabilitates the concept of effective rate of protection for use in political economy. The usual definition corresponds to no economically interesting magnitude in general equilibrium. The effective rate of protection for a sector is redefined here as the uniform tariff which is...
