Recent years have seen an emergence of decentralized cryptocurrencies that were initially devised as a payment system, but are increasingly being recognized as investment instruments.The price trajectories of cryptocurrencies have raised questions among economists and policy-makers, especially...

The massive price bubbles of decentralized cryptocurrencies, such as Bitcoin, have created a puzzle for economists. How can a non-revenue-generating asset exhibit such extreme price dynamics, forming multiple episodes of bubbles and crashes since its creation? The answer is not straightforward,...

We present an experiment designed to test the Modigliani-Miller theorem. Applyinga general equilibrium approach and not allowing for arbitrage among firmswith different capital structures, we find that, in accordance with the theorem, participantswell recognize changes in the systematic risk of...

We study survival, price impact and portfolio impact in heterogeneouseconomies. We show that, under the equilibrium risk-neutral measure,long-run price impact is in fact equivalent to survival, whereas longrunportfolio impact is equivalent to survival under an agent-specic,wealth-forward...

The pricing kernel puzzle is the observation that the pricing kernelmight be increasing in some range of the market returns. This paperanalyzes the pricing kernel in a nancial market equilibrium. If mar-kets are complete and investors are risk-averse and have common andtrue beliefs, the pricing...

In this paper, we experimentally test the Modigliani-Miller theorem. Applying ageneral equilibrium approach and not allowing for arbitrage among ¯rms with differ-ent capital structure, we are able to address a question fundamental to the valuationof firms: does capital structure affect the...

We derive representations for the stock price drift and volatility in theequilibrium of agents with arbitrary, heterogeneous utility functionsand with the aggregate dividend following an arbitrary Markov diffusion.We introduce a new, intrinsic characteristic of the aggregate dividendprocess that...

We consider a simple continuous-time economy, populated by a largenumber of agents, more risk averse than the log agent, with heterogeneousrisk aversion densely covering an interval. Even though thedividend is a geometric Brownian motion, the equilibrium investmentopportunity set is stochastic...

In all the existing literature on survival in heterogeneous economies,the rate at which an agent vanishes in the long run relative to anotheragent can be characterized by the difference of the so-called survivalindices, where each survival index only depends on the preferencesof the...

We perform a detailed asymptotic analysis of the equilibrium behavior of the assetprices, wealth size and portfolio weights in complete markets equilibria, with long-livedfunds. In equilibrium, the fund with the (closest to) log preference will dominate theother funds in size, in the long-run,...
