The literature on household asset accumulation draws a sharp distinction between "short-run" precautionary motives to buffer consumption from annual income shocks, and "long-run" life cycle considerations under income certainty. However, estimates of shock persistence imply considerable career...

This paper examines a decision-making problem of rational agents with risk averse utilities in the financial market both in statics and in dynamics. In the financial market there are two securities, one risky security and one riskless bond, and a continuum of investors with heterogeneous...

This paper analyses a temporary financial market equilibrium by considering a two-period model of asset pricing with s securities, one riskless bond, and a continuum of heterogeneous agents with different preferences, endowments, and beliefs. Investors' objectives are to maximize the expected...

In this paper we study the continuous time optimal portfolio selection problem for an investor with a finite horizon who maximizes expected utility of terminal wealth and faces transaction costs in the capital market. It is well known that, depending on a particular structure of transaction...

Existing findings suggest that standard, frictionless, expected-utility models have difficulty accounting for average and for median holdings of wealth and of risky assets, partly as a result of the largely unexplained limited proportion of stockholders among households. We analyze life-cycle...

This paper presents a dynamic, stochastic game-theoretic model of financial fragility. The model has two essential features. First, interrelated portfolios and payment commitments forge financial linkages among agents. Second, iid shocks to investment projects’ operations at a single date...

This paper proposes a framework for comovements of asset prices with seemingly unrelated fundamentals, as an outcome of optimal portfolio strategies by fund managers. In emerging markets, dedicated managers outperforming a benchmark index and global managers maximizing absolute returns lead to...

We apply a new approach to a new panel data set on bilateral=20 gross cross-border equity flows between 14 countries, 1989- 96. The model=20 integrates elements of the finance literature on portfolio composition and= =20 the international macroeconomics and asset trade literature. Gross asset=20...

What is the optimum quantity of money in a society? This paper answers this question both from the perspective of a utility maximizing model with real balances in the utility function, and employing an inventory theoretic model which focuses attention on the costs of transacting in different...

This paper decomposes the overall market beta of common stocks into four parts reflecting uncertainty related to the long-run dynamics of stock- specific and market-wide cash flows and discount rates. We employ a discrete time version of Merton�s Intertemporal CAPM to test whether these four...
