Richer and healthier agents tend to hold riskier portfolios and spend proportionally less on health expenditures. Potential explanations include health and wealth e ffects on preferences, expected longevity or disposable total wealth. Using HRS data, we perform a structural estimation of a...

Near the end of life, health declines, mortality risk increases and curative is replaced by uninsured long-term care, accelerating the fall in wealth. Whereas standard explanations emphasize inevitable aging processes, we propose a com- plementary closing down the shop justification where...

Lifetime financial-, work- and health-related decisions made by agents are intertwined with one another. Understanding how these decisions are made is essential to gauge if saving in financial, retirement and human assets is adequate or not. This paper numerically solves, simulates, and...

The ongoing SARS-CoV-2 pandemic is stressing the world population, health care system and economies at a level not experienced since WWII or the last “Spanish flu” pandemic of 1918. This shock provides a real-life test of the resilience of human societies, challenging our understanding and...

We present results on the mortality statistics of the COVID-19 epidemic in a number of countries. Our data analysis suggests classifying countries in five groups, 1) Western countries, 2) East Block , 3) developed South East Asian countries, 4) Northern Hemisphere developing countries and 5)...

This paper derives an analytic expression for the distribution of the average volatility $\frac{1}{T-t} \int_t^T \sigma_s^2 ds$ in the stochastic volatility model of Hull and White. This result answers a longstanding question, posed by Hull and White (Journal of Finance 42, 1987), whether such...

We analyze the implications of dynamic flows on a mutual fund manager's portfolio decisions. In our model, a myopic investor is allowed to dynamically allocate capital between a riskless asset and an actively managed mutual fund who charges fraction of fund fees. The presence of dynamic flows...

In this paper we present a modelling framework for portfolio credit risk which incorporates the dependence between risk-free interest-rates and the default loss process. The contribution in this approach is that - besides the traditional diffusion based covariation between loss intensities and...

This paper develops a real options framework to analyze the behavior of stock returns in mergers and acquisitions. In this framework, the timing and terms of takeovers are endogenous and result from value-maximizing decisions. The implications of the model for abnormal announcement returns are...

The Munich chain-ladder reserving method was introduced on an axiomatic basis. We analyze these axioms and we define a modified Munich chain-ladder reserving method which is based on an explicit stochastic model. This stochastic model then allows to consider claims prediction and prediction...
