The transition to a green technology is central to environmental policy. During such a transition, technology and market structure often change simultaneously, as firms developing the new technology enter the market of incumbents supplying the old one. This leads to the questions how...

In many countries, inducing large-scale technological changes has become an important policy objective, as in the context of climate policy or energy transitions. Such large-scale changes require the development of strongly interlinked technologies. But current economic models have little...

This paper aims to survey selected recent papers presenting new evidenceon an age-old question in financial economics: “Are stock market returnspredictable?”. The hypothesis that equity returns are predictable (specificallyat long horizons) has been called a “new fact in finance” by...

This paper surveys selected applications of the Lorenz curve and related stochasticorders in economics and econometrics, with a bias towards problems in statisticaldistribution theory. These include characterizations of income distributions in termsof families of inequality measures, Lorenz...

Arbitrage pricing cannot be applied to commodity futures because the physicalcommodity does not represent a pure asset: Since consumption and processing of thecommodity can drive down inventories to zero, it is not always possible to construct areplicating portfolio for the futures contract, and...

This paper examines properties of mean-variance inefficient proxieswith respect to producing a linear relation between expected returnsand betas. The numerical results of a Monte Carlo simulation showthat in the CAPM slightly inefficient, positively weighted proxies causean almost perfect linear...
