We study the accuracy and usefulness of automated (i.e., machine-generated) valuations for illiquid and heterogeneous real assets. We assemble a database of 1.1 million paintings auctioned between 2008 and 2015. We use a popular machine-learning technique - neural networks - to develop a pricing...

We construct a neural network algorithm that generates price predictions for art at auction, relying on both visual and non-visual object characteristics. We find that higher automated valuations relative to auction house pre-sale estimates are associated with substantially higher...

Aggregate art price patterns mask a lot of underlying variation — both in the time series and in the cross-section. We argue that, to increase our understanding of the market for aesthetics, it is helpful to take a micro perspective on the formation of art prices, and acknowledge that each...

Using historical price records for Bordeaux Premiers Crus, we examine the impact of aging on wine prices and the long-term investment performance of fine wine. In line with the predictions of an illustrative model, young maturing wines from high-quality vintages provide the highest financial...

What can studying the creation of knowledge tell us about how new technical fields emerge and develop? This paper shows how a knowledge community may be necessary to support the legitimacy of new products that undergo performance evaluation before purchase. Using historical and ethnographic data...

This note examines the investment performance of diamonds and other gems (sapphires, rubies, and emeralds) over the period 1999-2010, using a novel data set of auction transactions. Over our time frame, the annualized real USD returns for white and colored diamonds equaled 6.4% and 2.9%,...

We review the long-term investment performance of three important categories of emotional assets — stamps, art, and musical instruments. The long-run returns on these collectibles have been superior to the total return from government bonds and Treasury bills (and gold), at least before taking...

We assess the long-term financial returns from high-quality collectible real assets, and review the unique risks that are associated with such investments. Over the period 1900-2012, art, stamps, and musical instruments (violins) have appreciated at an average annual rate of 6.4%-6.9% in nominal...

This paper uses stamp catalogue prices to investigate the returns on British collectible postage stamps over the period 1900–2008. We find an annualized return on stamps of 7.0% in nominal terms, or 2.9% in real terms. These returns are higher than those on bonds but below those on equities....

The risk-return characteristics of art as an asset have previously been studied through aggregate price indexes. By contrast, we examine the long-run buy-and-hold performance of an actual portfolio, namely the collection of John Maynard Keynes. We find that its performance has substantially...
