Existing estimates of the annual unemployment rate from 1870 to 1913 were constructed by the Board of Trade, initially in 1888, and updated thereafter. This is still the series which is widely used and cited. It is based on records of the number unemployed in various trade unions and it has a...

Replication of two recent studies of growth determinants shows that results are sensitive to the choice of data from which growth rates are calculated, especially with respect to whether economic convergence has occurred. Previous warnings against using data that has been adjusted to increase...

This Paper studies a model where Information Technology, while typically increasing overall inequality, is likely to harm some people at intermediate and high levels of the distribution of income but to benefit people at the bottom; where within a given occupation it may harm some workers while...

Can the increasing significance of knowledge-products in national income---the growing weightless economy---influence economic development? Those technologies reduce ``distance'' between consumers and knowledge production. This paper analyzes a model embodying such a reduction. The model shows...

How does information technology (IT) affect the organization of police work? How does it in turn affect police crime-fighting effectiveness? To answer these questions, we construct a new panel data set of police departments covering 1987-2003. We find that while IT adoption had substantial...

This Paper uses a German employer-employee matched panel dataset to investigate the effect of organizational and technological changes on gross job and worker flows. The empirical results indicate that organizational change is skill-biased because it reduces predominantly net employment growth...

We study the earnings structure and the equilibrium assignment of workers when they exert intra-firm spillovers on each other. We allow for arbitrary spillovers provided output depends on some aggregate index of workers' skill. Despite the possibility of increasing returns to skills, equilibrium...

This Paper analyses the welfare benefits from falling relative prices of IT (Information Technology) goods across a wide range of countries. Using two separate methodologies and datasets, we find that welfare benefits mainly accrue to users of IT, not their producers, because of falling relative...
