Especially with the evaluation of non-listed (medium-sized) companies, the following problems and significant restrictions pertaining to the applicability of the CAPM must be taken into account when determining cost of capital. 1. Homogeneity of expectations and planning consistency. Given the...

The paper has two main objectives. The first is to test for the presence of the size and book-to-market value effects in the Visegrad countries. Such effects have been found in the United States and many other developed stock markets. The Visegrad countries consist of the Czech Republic,...

We examine if extreme weather exposure impacts firms’ cost of equity. Motivated by a consumption-based asset pricing model with heterogeneous agents, we reveal the existence of an extreme weather risk premium in the cross-section of stock returns. In the period from 1995 to 2019, domestic U.S....

I develop a model of collectibles tokenization to understand whether recent tokenization efforts create or destroy value. While issuing divisible security tokens against illiquid collectibles lowers transaction costs and facilitates greater portfolio diversification, security design...

Using data from 15 European Union economies, we quantify the real effects of supply-side frictions due to the financial disintegration of European countries since the 2008 financial crisis. We develop a multi-country general equilibrium model with heterogeneous countries and destination-specific...

It is widely held that better financial reporting makes investors more confident in their predictions of future cash flows and reduces their required risk premia. The logic is that more information leads necessarily to more certainty, and hence lower subjective estimates of firm "beta" or...

Risk concentration is a major outstanding explanation for crisis dynamics of asset prices and macroeconomic quantities. Apparently, capital flows are slow to correct these crises. By considering costly entry in a canonical limited participation model, I illustrate how asset prices encode costs...

For the popular mean-variance portfolio choice problem in the case without a risk-free asset, we develop a new portfolio strategy to mitigate estimation risk. We show that in both calibrations and real datasets, optimally combining the sample global minimum variance portfolio with a sample...

There are concerns that climate-related physical and political risks are not yet properly reflected in asset prices. To address these concerns, we develop a dynamic asset pricing framework with two sources of rare disasters: macroeconomic events and climate change. We link carbon emissions and...
