How big a boost to long run growth can countries expect from the ICT revolution? I use the results of growth accounting and the insights from a two-sector growth model to answer this question. The use of a two-sector rather than a one-sector model is required because of the very rapid rate at...

This paper presents annual estimates of fixed capital stocks and capital services for the United Kingdom, 1950-2013, for the whole economy and for the market sector. Our estimates cover eight asset types (structures, machinery, vehicles, computers, purchased software, own-account software,...

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...

This paper analyzes the welfare benefits from falling relative prices of IT (information technology) goods across a wide range of countries. We find, using two separate methodologies and datasets, that welfare benefits mainly accrue to users of IT, not their producers, because of falling...

This paper uses a model of growth and imperfect capital mobility across multiple economies to characterize the dynamics of (cross-country) in- come distributions. This allows convenient study of the convergence hypothesis, and reveals, where appropriate, polarization and clumping within...

This paper studies cross-country patterns of economic growth from the viewpoint of income distribution dynamics. Such a perspective raises new empirical and theoretical issues in growth analysis: the profound empirical regularity is an \emerging twin peaks" in the cross-sectional distribution,...

This paper uses recently developed methods for estimating dynamic heterogeneous cointegrated panel data models - which allows for heterogeneity in parameters and dynamics across agents - to study housing wealth effects in a dynamic model of the 50 US states and the District of Columbia from the...

This paper models uctuations in regional disaggregates as a nonsta- tionary, dynamically evolving distribution. Doing so enables study of the dynamics of aggregate uctuations jointly with those of the rich cross-section of regional disaggregates. For the US, the leading state| regardless of...

This report presents two of our investigations: one is to obtain an accurate forecast for the corporate bankruptcy; the other is to obtain a physical default intensity. Both investigations were based on the hazard model, using only firm-specific accounting variables as predictors. Different...

We propose a rational theory of momentum and reversal based on delegated portfolio management. A competitive investor can invest through an index fund or an active fund run by a manager with unknown ability. Following a negative cashflow shock to assets held by the active fund, the investor...
