Can stock market bubbles accelerate long term growth? Do such bubbles indicate irrational behavior? This paper studies the effect of innovation uncertainty on the concomitant time path of firm valuations, technology adoption and growth in a setting that incorporates positive network...

Since at least the mid-2000's, many advanced economies have experienced low productivity growth. This development is often related to the declining productivity gains at the technology frontier, which is commonly assumed to be determined by the U.S. We challenge this explanation by studying the...

Using a newly assembled dataset of U.S. patents, we show that overall innovation activity is less concentrated in high-density urban areas than commonly believed, but inventions based on atypical combinations of knowledge are indeed more prevalent in high-density cities. To interpret this...

This paper estimates the aggregate productivity effects of Marshallian externalities generated by foreign direct investments (FDI) in the US. In contrast to earlier work, this paper puts special emphasis on controlling for Marshallian externalities and other intra- and inter-regional spillovers...

The validity of existing empirical tests of the Pollution Haven Hypothesis (PHH) is constantly under scrutiny due to two shortcomings. First, the issues of unobserved heterogeneity and measurement error in environmental regulation are typically ignored due to the lack of a credible, traditional...

Most studies of foreign direct investment (FDI) spillovers focus on externalities of inward FDI to host country firms. However, spillovers may also be generated from outward FDI and flow to home country firms. We test for the presence of spillovers from U.S. multinational corporations to...

We empirically analyse the response of US manufacturing labour market variables to various shocks, notably to trade openness and technology. The econometric approach involves an application of the recently developed global VAR (GVAR) methodology of Dees, DiMauro, Pesaran, and Smith (2005) to 12...

Since 1980, there has been a steady increase in earnings inequality alongside rapid technological growth in the U.S. economy. To what extent does technological change explain the observed increase in earnings dispersion? How does it affect the optimal progressivity of the tax system? To answer...

Empirical results on the link between growth and diversity in (un)related industries proved to be highly dependent on the specific regional and temporal context. Making use of highly disaggregated employment data at the sub-regional level, we find that higher employment growth in Austria is...
