We develop a new class of artificial stock market that apply general equilibrium price clearing. Our model is the first multi-asset artificial stock market to use exogenously generated dividends from a geometric vector autoregressive model and is therefore the first truly multi-asset artificial stock market. Our model does not require the concept of a risk free asset and agents are able to form...

Agents and endowments. There is a continuum of ex ante identical households, a large number of perfectly competitive financial intermediaries, and a government. As in a typical cash-inadvance economy each household splits into a worker and a shopper each period. Each period each household receives an idiosyncratic endowment y ∈ [0,∞) that is IID in the population and IID over time with density ...

We combine the theory of finite-dimensional lattice subspaces and the theory of regular values for maps between smoothmanifolds in order to study the completion of real asset markets by options. The strike asset of the options is supposed to be a nominal asset. The main result of the paper is like in the case of the completion of a nominal asset market by options that if the strike asset of the...

My dissertation studies the impact of economic linkages among market participants on equilibrium outcomes such as asset prices and returns as well as investors’ welfare. The first essay—titled “Inter-firm Relationships and Asset Prices”—studies the asset pricing properties that stem from the propagation of shocks within a network economy and the extent to which such a propagation mechanism quan...

We study an over-the-counter (OTC) market with bilateral meetings and bargaining where the usefulness of assets, as means of payment or collateral, is limited by the threat of fraudulent practices. We assume that agents can produce fraudulent assets at a positive cost, which generates endogenous upper bounds on the quantity of each asset that can be sold, or posted as collateral in the OTC mark...

The quality of information in financial asset markets is often hard to estimate. This paper analyzes information transmission in asset markets when agents treat information of unknown quality as ambiguous. We study the effects of information ambiguity on asset prices, trading volume, and market liquidity in noisy rational expectations equilibrium. We consider a market with risk-averse informed ...

Using a data set on more than 300 UK pension funds' asset holdings, this paper provides a systematic investigation of the performance of managed portfolios across multiple asset classes. We ̄nd evidence of slow mean reversion in the funds' portfolio weights towards a common, time-varying strategic asset allocation. We also ̄nd surprisingly little cross-sectional variation in the average ex post...

The growing share of financial assets that are held and managed by large institutional investors whose trades move prices contradicts the traditional asset pricing paradigm which assumes markets are competitive with small price-taking players. This paper relaxes the traditional price-taking assumption and instead presents a dynamic multi-asset, multi-large participant model of imperfect competi...
