We use portfolio theory to quantify the efficiency of state-level sectoral patterns of production in the United States. On the basis of observed growth in sectoral value-added output, we calculate for each state the efficient frontier for investments in the real economy. We study how rapidly...

This paper studies the relationship between investor protection, financial risk sharing and income inequality. In the presence of market frictions, better protection makesinvestors more willing to take on entrepreneurial risk while lending to firms. This implies lower cost of external finance...

We analyze the investment behavior of private clients concerning structured products. To ascertain their stated and revealed preferences, we use a questionnaire and a field experiment, respectively. The real product issued in the field experiment is comparable to one product in the questionnaire...

The main objective of this work is to develop a general equilibrium business cycle model linking financial and real estate markets to the macroeconomy. The ability of a production economy to account simultaneously for asset pricing, business cycle and real estate market facts is then evaluated...

What is the fundamental value of a stock? Do stock prices deviate from this fundamental value? If yes, do they go back to their fundamental value? This paper proposes to answer these three questions by using a stock valuation model based on the Consumption-Capital Asset Pricing Model (C-CAPM)...

The large spread between equity returns and risk free rates observed in most stock markets (the "equity premium puzzle") has been subject of intense debates. Two main families of models claim to solve this puzzle: habit formation models and loss aversion models. The goal of this paper is to...

We analyse questions of arbitrage in financial markets in which asset prices change in time as stationary stochastic processes. The main focus of the paper is on a model where the price vectors are independent and identically distributed. In the framework of this model, we find conditions that...

In this paper, we consider an investor who plays in a market that involves a risky asset whose instantaneous rate of return changes at unknown random times. This return rate is assumed to follow the law of a Compound Poisson Process. We construct optimal mathematical strategies in this context...

We aim to compare financial technical analysis techniques to strategies which depend on a mathematical model. In this paper, we consider the moving average indicator and an investor using a risky asset whose instantaneous rate of return changes at an unknown random time. We construct...

The goal of this paper is to assess, for the first time, the empirical impact of "Kaynes' beauty contest", or "higher order belief", on asset price volatility. The paper shows that heterogeneous expectations induce higher order beliefs and that heterogeneous expectation asset pricing models...
