This study focuses on dynamic asset pricing implications for consumption and portfolio shares. First, we exploit the investors' intertemporal budget constraint and the induced national saving identity to construct US total wealth. We then document the empirical shares using aggregate consumption...

I identify circumstances in which an agent wants to make a costly but unobservable irreversible investment that affects the subsequent noisy economic environment. In equilibrium, rivals may eventually infer that the agent is strong even though it initially appeared weak, so long as enough...

Personal projects, such as a private business or the purchase of a home, influence portfolio choice in two ways. First, financial assets can be used to provide diversification against bad outcomes of personal projects. Second, financial assets can be used to provide liquidity to personal...

We show that unconditionally efficient returns do not achieve the maximum unconditional Sharpe ratio, neither display zero unconditional Jensen’s alphas, when returns are predictable. Next, we define a new type of efficient returns that is characterized by those unconditional properties. We...

In this paper we propose a subsampling estimator for the distribution of statistics diverging at either known rates when the underlying time series in strictly stationary abd strong mixing. Based on our results we provide a detailed discussion how to estimate extreme order statistics with...

This paper proposes to estimate the covariance matrix of stock returns by an optimally weighted average of two existing estimators: the sample covariance matrix and single-index covariance matrix. This method is generally known as shrinkage, and it is standard in decision theory and in empirical...

We propose new spanning tests that assess if the initial and additional assets share the economically meaningful cost and mean representing portfolios. We prove their asymptotic equivalence to existing tests under local alternatives. We also show that unlike two-step or iterated procedures,...

The basic financial purpose of a firm is to maximize its value. An inventory management system should also contribute to realization of this basic aim. Many current asset management models currently found in financial management literature were constructed with the assumption of book profit...

Risk has become an important variable in many areas of research. Measures of risk have been included in research on corporate products diversification, international geographic diversification, vertical integration, business strategy and industry characteristics, organizational process and...

In this paper we provide a brief introduction to the literature on agent-based financial modelling and, more specifically, artificial stock market modelling. In the selective literature review two broad categories of artificial stock market models are discussed: models based on hard-wired rules...
