This article applies recent advances in productivity and efficiency measurement to the evaluation of skillbiased technical change. Using the general index approach we are able to establish an explicit and unconstrained time path for nonneutral technical change between production and...

This chapter considers the evidence on productivity growth in transportation industries and provides a critical review of efforts to distinguish the nature and sources of technical progress. Regulatory reform and technological advance have contributed to productivity growth that is nonneutral...

This article introduces a two-step empirical approach for examining both the nature and sources of non-neutral technical change across multiple occupations. First, conventional labour-demand parameter estimates and unbiased tests for neutrality are obtained in the context of a flexible cost...

The traditional concentration of basic research activities in academic settings, with applied research more prevalent in industrial settings, is a distinguishing feature of science and technology markets. This structure arises from a unique combination of product characteristics, and in turn it...

This paper updates Baltagi's (2003, Econometric Theory 19, 165-224) rankings of academic institutions by publication activity in econometrics from 1989-1999 to 1989-2005. This ranking is based on 16 leading international journals that publish econometrics articles. It is compared with the prior...

This paper studies the performance of panel unit root tests when spatial effects are present that account for cross-section correlation. Monte Carlo simulations show that there can be considerable size distortions in panel unit root tests when the true specification exhibits spatial error...

This paper examines the consequences of model misspecification using a panel data model with spatially autocorrelated disturbances. The performance of several maximum likelihood estimators assuming different specifications for this model are compared using Monte Carlo experiments. These include...

This paper considers the problem of prediction in a panel data regression model with spatial autocorrelation in the context of a simple demand equation for liquor. This is based on a panel of 43 states over the period 1965-1994. The spatial autocorrelation due to neighboring states and the...
