This paper develops a tractable stochastic overlapping generations model to analyze the equilibrium equity premium and growth rate of the capital stock in the presence of a defined-benefit Social Security system. If the Social Security Trust Fund increases the share of its portfolio held in...

Equity mutual funds earn large positive returns on the last day of the year, and large negative returns on the following day. The same applies on a smaller scale at quarter-ends that aren't month-ends. Empirical evidence from a variety of sources, including portfolio disclosures and intra-day...

We investigate the robustness of the long-run underperformance of initial public offering (IPO) and seasoned equity offering (SEO) firms from 1975-1992. The conclusion that issuer underperformance is unique is questioned by our results. We find that underperformance is largely concentrated in...

Limit orders incur no price impact, however, their execution time is uncertain. We develop several econometric models of limit-order execution times using survival analysis, and estimate them with actual limit-order data. We estimate models for time-to-first-fill and time-to-completion, and for...

We study the problem of a firm that is controlled by a large shareholder and is going public in the presence of agency problems, asymmetric information, and trading of shares over time. In this multiperiod signalling game, a shareholder-manager can develop a reputation for expropriating low...

Large shareholders of firms with majority blocks are often at the helm of their companies and do not necessarily have the same interests as minority shareholders. We show that bargaining problems led by the presence of multiple controlling shareholders protect minority shareholders. The same...

Implications of factor-based asset pricing models for estimation of expected returns and for portfolio selection are investigated. In the presence of model mispricing due to a missing risk factor, the mispricing and the residual covariance matrix are linked together. Imposing a strong form of...

Using a database of branch managers in retail banks, this study finds some empirical support for the two main predictions of Jensen and Meckling's (1992) theory on organizational design choices: a) the allocation of decision rights to branch managers is associated with control systems that...

We study the asset pricing implications of an economy where solvency constraints are determined to efficiently deter agents from defaulting. We present a simple example for which efficient allocations and all equilibrium elements are characterized analytically. The main model produces large...

In this paper we review the evidence on the cross-sectional behavior of common stock returns on the U.S. and other equity markets around the world. We also report some new evidence on these cross-sectional relations using data from both U.S. and international stock markets. We find, among other...
