The impact of food assistance programs (food stamps) in a period of rising income inequality in
the US is analyzed using 1978-1992 PSID data. We assess to what extent food assistance can be
viewed...

The dramatic rise in crop prices that occurred in the fall of 2006 was the
beginning of an unprecedented level of volatility in agricultural markets. For example,
corn prices for most of this de...

We establish the duality-formula for the superreplicationprice in a setting of volatility uncertainty which includes the example of “random G-expectation.” In contrast to previous results, the conting...
Revisiting the fractional cointegrating dynamics of implied-realized volatility relation with wavelet band spectrum regression
wavelet band spectrum regression corridor implied volatility realized volatility fractional cointegration

This paper revisits the fractional cointegrating relationship between ex-ante implied volatil-ity and ex-post realized volatility. We argue that the concept of corridor implied volatility (CIV) should...
Local L関y Models and their Volatility Smile
CEV L磂vy Local Volatility Implied Volatility Default
2012/9/14
We propose a class of equity models whose volatility, L磂vy measure, and killing rate all have local stochastic state-dependence. In this framework we find a closed form solution for the price of any E...
The Exact Smile of some Local Stochastic Volatility Models
CEV local volatility stochastic volatility implied volatility.
2012/9/14
We introduce a class of local stochastic volatility models.Within our framework, we obtain an expression for both (i) the price of any European option and (ii) the induced implied volatility smile. To...
A new look at short-term implied volatility in asset price models with jumps
exponential Levy models Blumenthal-Getoor index short-dated options implied volatility.
2012/9/14
We analyse the behaviour of the implied volatility smile for options close to expiry in the exponential Levy class of asset price models with jumps. We introduce a new renormalisation of the strike v...
