of a Function from its Moments”*

**

/_Abstract:_//  /

/We discuss sampling expansions for functions in reproducing kernel 
Hilbert and Banach spaces. We also consider generalizations of the 
Backus-Gilbert method for reconstruction a function from its moments,
both on the real line and on the sphere, in  appropriate reproducing 
kernel Hilbert spaces. /

*„The Limits of Leverage“*

**

Abstract:

If trading incurs proportional costs, leverage can scale the return of 
an asset only up to a maximum multiple, which is sensitive to the 
asset's volatility and liquidity. In a continuous-time model with one 
safe and one risky asset,
with constant investment opportunities and proportional transaction 
costs, we find the family of mean-variance efficient portfolios over a 
long horizon. As leverage and volatility increase, rising rebalancing
costs imply a declining Sharpe ratio. Beyond a critical level, even the 
expected return declines. We also derive the optimal tradeoff between 
alpha and tracking error for funds that seek to replicate multiples of 
index returns, such as leveraged ETFs.
