We present a new data set we built based on Swiss rich lists going back to 1989. We show, among other things, that 60% of the super-rich are heirs—a fraction twice as large as in the US—and that wealth mobility at the very top has declined significantly. We find that top 0.01% wealth shares...

We collect, digitize, and supplement the Swiss rich list for the years 1989–2020 published in the "BILANZ" business magazine to gain new insights on the structure and dynamics of top wealth in Switzerland. Using this data allows us study the super-rich in Switzerland in ways that were not...

Two-sided platform firms serve distinct customer groups that are connected through interdependent demand, and include major businesses such as the media industry, banking, and the software industry. A well known textbook result in one-sided markets is that a government may increase a...

Newspapers are two-sided platforms that sell their product both to readers and advertisers. Media firms in general, and newspapers in particular, are considered important providers of information, culture and language in most countries. Newspapers are therefore given preferential tax treatment....

This paper examines the efficient provision of goods in two-sided markets and characterizes optimal specific and ad-valorem taxes. We show that (i) a monopoly may have too high output compared to the social optimum; (ii) output may be reduced by imposing negative value-added taxes (subsidy) or...

Empirical evidence suggests that people dislike ads in media products like TV programs. In such situations standard economic theory prescribes that the advertising volume can be optimally reduced by levying a tax on ads. However, making use of recent advances in the theory of Industrial...

Many countries levy reduced-rate indirect taxes on newspapers, with proclaimed policy goals of stimulating investment in journalism and ensuring low newspaper prices. However, by taking into account the fact that the media industry operates in two-sided markets, we find the paradoxical result...

This paper shows that consumers may buy more of a taxed good if it is sold by a two-sided platform firm. Two-sided platform industries serve distinct customer groups that are connected through interdependent demand, and include major businesses such as the media industry (newspapers/magazines...

We estimate the ratio of private wealth to national income, βpt, for Switzerland from 1900 to 2020. Our results indicate that over the 20th century, βpt did not follow a U-shaped pattern as in most European countries. Instead, its was exceptionally stable at around 500%. We argue that this...
