We study a simple rational expectations (RE) model whose asset pricing implications address some of the short-run mispricings, informational inefficiencies, and overreactions observed in real markets, without a need to resort to behavioral assumptions. We accomplish this by relying on the...

We provide a historical perspective focusing on Ziemba's experiences and research on the bond-stock earnings yield differential model (BSEYD) starting from when he first used it in Japan in 1988 through to the present in 2014. The model has called many but not all crashes. Those called have high...

One of the most contentious issues raised during the recent crisis has been the potentially exacerbating role played by mark-to-market accounting. Many have proposed the use of historical cost accounting, promoting its ability to avoid the amplification of systemic risk. We caution against...

I document how the organizational form of a mutual fund aects its investment strategies. I show that centralized funds tilt their portfolios to hard information com- panies whereas decentralized funds tilt their portfolios to soft information companies. I also show that the investments of...

Current approaches to asset-liability management employ a sequence of distinct procedures to value liabilities and determine the asset allocation. First, a discount rate that is usually dic-tated by accounting standards is used to value liabilities. Second, the asset allocation is determined by...

This paper considers the asset-allocation strategies open to members of defined- contribution pension plans. We investigate a model that incorporates three sources of risk: asset risk and salary (or labour-income) risk in the accumulation phase; and interest-rate risk at the point of retirement....

One can consider the concept of market neutrality for hedge funds as having breadth and depth: breadth reflects the number of market risks to which a fund is neutral, while depth reflects the completeness of the neutrality of the fund to market risks. We focus on market neutrality depth, and...

This paper provides evidence that managers adjust firm advertising, in part, to attract investor attention and influence short-term stock returns. First, I show that increased advertising spending is associated with a contemporaneous rise in retail buying and abnormal stock returns, and is...

We consider a noisy rational expectations equilibrium in a multi-asset economy populated by informed and uninformed investors, and noise traders. Informed investors privately observe an aggregate risk factor affecting the probabilities of different states of the economy. Uninformed investors...
