We analyze the implications of entrepreneurial spawning for a variety of firm characteristicssuch as size, focus, profitability, and innovativeness. We examine the dynamics of spawning overtime. Our model accounts for much of the empirical evidence relating to the relation betweenspawning and...

We present and compare two dierent approaches to conditional riskmeasures. One approach draws from convex analysis in vector spaces andpresents risk measures as functions on Lp spaces, while the other approachutilizes module-based convex analysis where conditional risk measures aredened on Lp...

Many statistical applications require an estimate of a covariance matrix and/or its inverse.When the matrix dimension is large compared to the sample size, which happensfrequently, the sample covariance matrix is known to perform poorly and may suffer fromill-conditioning. There already exists...

The …xed rate tender is one of the main operational formats usedby central banks in the implementation of their monetary policies. Whileacademic research has largely dismissed the procedure for its tendency to en-courage overbidding, central banks such as the ECB and the Bank of Englandhave...

A large literature studies the predictability of stock returns by other lagged nancialvariables in a predictive regression setting. A common feature of widely used testingprocedures is a failing robustness, which may lead to misleading conclusions determinedby the particular features of a small...

This paper empirically investigates how the intensity of product market competitionaffects the cost of debt. Using a large sample of loans to publicly traded US manufac-turing fi…rms, I provide evidence that an intensi…fication of product market competitionamong fi…rms signifi…cantly...

The recursive prediction and filtering formulas of the Kalman filter are difficult to implementin nonlinear state space models. For Gaussian linear state space models, or for models with qualitativestate variables, the recursive formulas of the filter require the updating of a finite number...

Recent crises have seen very large spikes in asset price risk without dramatic shiftsin fundamentals. We propose an explanation for these risk panics based on selffullling shifts in risk made possible by a negative link between the current assetprice and risk about the future asset price. This...

In a Lucas orchard with heterogeneous beliefs, we study the link between market-wide uncertainty, difference of opinionsand co-movement of stock returns. We show that this link plays an important role in explaining the dynamics of equilibriumvolatility and correlation risk premia. In our...

Richer and healthier agents tend to hold riskier portfolios and spend proportionallyless on health expenditures. Potential explanations include health and wealth eects onpreferences, expected longevity or disposable total wealth. Using HRS data, we perform astructural estimation of a dynamic...
