We present the R package trajeR which provides all necessary tools to calibrate generalized finite mixture models, plot the results graphically and test the model adequacy.First, we give an overview of the generalized finite mixture model for clustering time series and describe the core function...

This paper investigates whether the overpricing of out-of-the money single stock calls can be explained by Tversky and Kahneman's (1992) cumulative prospect theory (CPT). We hypothesize that these options are expensive because investors overweight small probability events and overpay for...

We document that public interventions in the corporate sector during the COVID-19 pandemic help firms access bank loans, cushion liquidity shortfalls, and boost their market valuations. We use firm-level data on COVID-19-related news to trace firms’ liquidity shocks in several European...

We provide evidence that culture is a source of pricing bias. In a sample of 1.9 million auction transactions in 49 countries, paintings by female artists sell at an unconditional discount of 42.1%. The gender discount increases with measures of country-level gender inequality — even in artist...

House prices have increased faster than average income in many countries over the last decade, raising concerns on the affordability of housing. We study the impact of transaction taxes on the real estate market and the effectiveness of tax subsidies to make housing more affordable. We show how...

The Lucas (1978) Tree Model lies at the heart of modern macro-finance. At its core, it provides an analysis of the equilibrium price of a long-lived asset in an exchange economy where consumption is the objective, and the sole purpose of the asset is to smooth consumption through time....
