On the equivalence between labor and consumption taxation
This article studies the equivalence between labor and consumption taxes in a stochastic context, where the government can undertake an active portfolio management strategy by investing in both risk-free and risky assets. Using a two-period model we have shown that such taxes let consumers make the same decisions and can finance the same amount of government spending in each period.consumption and labor taxation, equivalence, risk.

Comment on: "Analytical approximations for the collapse of an empty spherical bubble"
We analyze the Rayleigh equation for the collapse of an empty bubble and
provide an explanation for some recent analytical approximations to the model.
We derive the form of the singularity at the second boundary point and discuss
the convergence of the approximants. We also give a rigorous proof of the
asymptotic behavior of the coefficients of the power series that are the basis
for the approximate expressions
Bound states for the quantum dipole moment in two dimensions
We calculate accurate eigenvalues and eigenfunctions of the Schr\"odinger
equation for a two-dimensional quantum dipole. This model proved useful for the
study of elastic effects of a single edge dislocation. We show that the
Rayleigh-Ritz variational method with a basis set of Slater-type functions is
considerably more efficient than the same approach with the basis set of
point-spectrum eigenfunctions of the two-dimensional hydrogen atom used in
earlier calculations
On the mean square error of randomized averaging algorithms
This paper regards randomized discrete-time consensus systems that preserve
the average "on average". As a main result, we provide an upper bound on the
mean square deviation of the consensus value from the initial average. Then, we
apply our result to systems where few or weakly correlated interactions take
place: these assumptions cover several algorithms proposed in the literature.
For such systems we show that, when the network size grows, the deviation tends
to zero, and the speed of this decay is not slower than the inverse of the
size. Our results are based on a new approach, which is unrelated to the
convergence properties of the system.Comment: 11 pages. to appear as a journal publicatio
