We investigate a switch from fixed-weighted national accounts data to chain-type data in the quarterly macroeconometric model Mona. As in other countries the idea behind this change in the national accounts data has been to reduce the substitution bias, which has grown with the amount of...

This paper proposes a multi-sector matching model where workers have (symmetric) sector-specific skills and the search market is segmented by sector. Workers choose the range of markets they are willing to participate in. I identify a composition externality: workers do not take into account the...

We use US regional and state data to determine which regions have contributed most to the apparent decline in income growth volatility in the United States. We study changes in the variance of income growth in each region, changes in the covariance of growth between regions and changes in...

This paper uses micro data from the New Earnings Survey to document that cross-sectional wage inequality in the U.K., which rose sharply in the 1980s and continued to rise moderately through the mid-1990s, has remained essentially unchanged in the latter half of the 1990s. As in the U.S.,...

This paper presents new evidence that increases in college enrollment lead to a decline in the average quality of college graduates between 1960 and 2000, resulting in a decrease of 6 percentage points in the college premium. We show that although a standard demand and supply framework can...

What happens when liquidity increases in credit markets and more funds are channeled from borrowers to lenders? We examine this question in a general equilibrium model where financial matchmakers help borrowers (firms) and lenders (households) search out and negotiate profitable matches and...

We develop a model with endogeneity in key features of industrial structure linked to heterogeneous cost structures under Cournot competition. We use the model to explore issues related to cross-country differences in industry structure and the impact of globalization on markups and pricing,...
