Welfare gains from increasing product variety are an important source of the gains from international trade. Recent empirical studies have largely focused on measuring the gains from an increased variety of imports. Trade theory, however, suggests that international trade heavily affects the...

This paper examines the unprecedented decimation of sharks. We develop a Ricardian Gordon-Schaefer model with a continuum of heterogeneous species which are subject to combined harvesting and perfect substitutability in consumption. The model implies that slow-growing species, surviving in...

Real-world data (RWD) are an increasingly important input into the pharmaceutical R&D process as shown by countries like the USA or Finland. As the availability of and access to Swiss RWD is rather limited, the question arises whether this creates a burden for pharmaceutical R&D in Switzerland....

Despite tremendous growth in the volume of new scientific and technological knowledge, the popular press has recently raised concerns that disruptive innovative activity is slowing. These dire prognoses were mainly driven by Park et al. (2023), a Nature publication that uses decades of data and...

As is well known, the uncovered interest rate parity fails in the short run but usually holds in the long run. This paper analyses the long and short run interest rate parity of 10 mayor OECD currencies and finds that there is a long run failure of the uncovered interest rate parity condition...

This paper revisits the puzzle of low returns on Swiss Franc assets using a new data set of portfolio holdings of residents and non residents at Swiss banks. The main findings are as follows. First, we find that the return anomaly is present only for fixed income assets and not for equity....
