The existing replication policies at top finance journals are far weaker than the policies at top economics journals. This paper explores both the costs and benefits of having a stronger replication policy in the context of my failed 2010 initiative to develop a unified policy across all top...

Using close to 800,000 transactions by 66,000 households in the United States and close to 2,000,000 transactions by 303,000 households in Finland, this paper shows that individual investors with longer holding periods choose to hold less liquid stocks in their portfolios, consistent with Amihud...

Liquidation of large portfolios in practice requires a longer time and smaller relative selling speed than the liquidation of small portfolios. Mean-variance optimal liquidation however results in the same relative selling speed and time horizon for small and large positions. We discuss three...

Bonds issued in high and low interest-rate environments often list at different prices despite very similar characteristics. From a risk-neutral investor's perspective, higher current prices imply higher losses in case of default, which must be compensated, if markets are efficient. We call this...

We introduce a new discounted cash flow model which integrates the diversification effect of multi-business firms. We face two challenges. One is examining how different degrees of diversification can affect firm value due to risk reduction, and the other is modeling segment-specific cash flows...

Our paper investigates spillover effects across different business segments of publicly traded financial conglomerates. We find that the investment decisions of mutual fund shareholders do not just depend on the prior performance of the mutual funds, they also depend on the prior performance of...

We use a unique loan-level dataset to compare portfolio and securitized commercial real estate loans. The paper documents how the types of loans banks choose to hold in their portfolios differ substantially from the types of loans the same banks securitize. Banks tend to hold loans that are...

In this paper we have developed a financial model of the non-life insurer to provide assistance for the management of the insurance company in making decisions on product, investment and reinsurance mix. The model is based on portfolio theory and recognizes the stochastic nature of and the...

We propose a reduced form model for default that allows us to derive closed-form solutions to all the key ingredients in credit risk modeling: risk-free bond prices, defaultable bond prices (with and without stochastic recovery) and probabilities of survival. We show that all these quantities...

This paper contrasts the valuation of accounting numbers related to two classes of assets - the internally managed, fully-controlled assets versus the "significant influence" investments, that is, investments where the investing firm exercises influence, but not control, over the assets. We find...
