We consider fundamental questions of arbitrage pricing arising when the uncertainty model incorporates volatility uncertainty. With a standard probabilistic model, essential equivalence between the absence of arbitrage and the existence of an equivalent martingale measure is a folk theorem, see...

This paper evaluates the strength of information flow from employed past coworkers on the re-employment duration of displaced workers due to plant closures in Austria. Using the Austrian Social Security Database (a matched employer-employee database) we exploit the panel structure of 36 years of...

We use the Shapley value and the nucleolus to analyze the impact of three controversial pipeline projects on the power structure in the Eurasian trade of natural gas. Two pipelines, `Nord Stream' and `South Stream', allow Russian gas to bypass transit countries, Ukraine and Belarus. The third...

The last century has witnessed dramatic changes in the world economy. The service (tertiary) sector, which at the beginning of the 20th century was of little importance relative to agriculture and manufacturing, has become the dominant sector today, accounting for 80% and more of value added in...

Job polarization is a widely documented phenomenon in developed countries since the 1980s: employment has been shifting from middle to low- and high-income workers, while average wage growth has been slower for middle-income workers than at both extremes. We document 1) that polarization has...

This paper examines job polarization at the level of local labor markets in Germany over a 30-year period. The major explanation of job polarization is skill biased technological change (SBTC): new technologies are complementary to high paying jobs but substitute workers in routine manual jobs...

Science, innovation, knowledge and digital technologies have played a fundamental role in the growth potential, social inclusion and environmental sustainability of countries in recent decades, and have become even more important in the context of the crisis caused by the coronavirus disease...

This paper analyzes revenue and welfare effects of implementing a FAT both from a theoretical and a quantitative perspective. The theoretical analysis allows us to derive expressions for the revenue effects and the deadweight loss in a general equilibrium setting, which can be quantified with a...

We develop a quantitative framework in which income inequality arises endogenously in response to productivity shocks. The framework accommodates sectoral inputoutput linkages, arbitrary elasticities of factors and intermediates, and heterogeneous workers that endogenously choose to supply their...
