Asset pricing under asymmetric informationHäfke, Christian, Sögner, Leopold January 1999 (has links) (PDF)
This article investigates the impacts of asymmetric information within a Lucas (1978) asset pricing economy. Asymmetry enters via the assumption that one group of agents is equipped with superior information about the dividend process. The agents maximize their lifetime utility of the underlying consumption process obtained from the agents' budget constraints, where the agents have the opportunity to invest in a risk asset to transfer income from the current to future periods. Since a closed form solution for the market price cannot be derived analytically, projection methods are applied, as described in Judd (1998), to approximate the expectation integrals in the agents' Euler equation. We derive the result that the informed trader only clearly improves his situation as compared to the non-trade situation if the uninformed trader only observes his own endowment but not the endowment of the informed trader. In the case where agents observe each others' endowment trade never results in a Pareto improvement.

Essays in Finance and Macroeconomics: Household Financial Obligations and the Equity PremiumJanuary 2017 (has links)
abstract: This dissertation is a collection of three essays relating household financial obligations to asset prices. Financial obligations include both debt payments and other financial commitments.
In the first essay, I investigate how household financial obligations affect the equity premium. I modify the standard Mehra-Prescott (1985) consumption-based asset pricing model to resolve the equity risk premium puzzle. I focus on two channels: the preference channel and the borrowing constraints channel. Under reasonable parameterizations, my model generates equity risk premiums similar in magnitudes to those observed in U.S. data. Furthermore, I show that relaxing the borrowing constraint shrinks the equity risk premium.
In the Second essay, I test the predictability of excess market returns using the household financial obligations ratio. I show that deviations in the household financial obligations ratio from its long-run mean is a better forecaster of future market returns than alternative prediction variables. The results remain significant using either quarterly or annual data and are robust to out-of-sample tests.
In the third essay, I investigate whether the risk associated with household financial obligations is an economy-wide risk with the potential to explain fluctuations in the cross-section of stock returns. The multifactor model I propose, is a modification of the capital asset pricing model that includes the financial obligations ratio as a ``conditioning down" variable. The key finding is that there is an aggregate hedging demand for securities that pay off in periods characterized by higher levels of financial obligations ratios. The consistent pricing of financial obligations risk with a negative risk premium suggests that the financial obligations ratio acts as a state variable. / Dissertation/Thesis / Doctoral Dissertation Economics 2017

Záhada prémie vlastního kapitálu: přehled literatury a česká data / Equity Premium Puzzle: Literature Review and the Czech DataHrachovec, Miloš January 2013 (has links)
This thesis focuses on the equity premium puzzle, risk-free rate puzzle and possible solutions of these two quantitative conundrums. Original formulation of both puzzles is introduced and comprehensive literature survey is presented to show the developments regarding this topic. These include risk-based explanations, non-risk based explanations and behavioral finance perspective. Main contribution of this study dwells in estimation of these two puzzles for the Czech Republic. Using consumption-based asset pricing model with time separable preferences, presence of the two puzzles is estimated employing annual Czech data from 1995 to 2011. The equity premium puzzle is not present in the Czech Republic, as the coefficient of risk aversion 5.57 . On the other hand, the risk-free rate puzzle is as severe as in developed economies. Furthermore, the individual time preference parameter is estimated to be larger than one - a counterintuitive result suggesting consumers prefer unit of consumption tomorrow to unit of consumption today. Robustness of the results is confirmed when different proxy for a risk-free rate is used. Results do not change significantly and the risk-free rate puzzle persists. Direction for future research of the financial market puzzles in the Czech Republic is suggested.
