Equilibrium Exchange Rate Hedging [PDF]

In a one-period model where each investor consumes a single good, and where borrowing and lending are private and real, there is a universal constant that tells how much each investor hedges his foreign investments.

Principal-Agent Problem with Minimum Performance Insurance [PDF]

A minimum performance insurance in the Principal-Agent problem is wealth reducing to the principal. This result points to further inefficiencies in mandatory individual Pension Funds' contracts, particularly the one established in the 1993's 100th Law in

The Log of Gravity [PDF]

Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: the standard practice of interpreting the parameters of log-linearized models estimated by ordinary least ...

Unveiling new reverse Hilbert-type dynamic inequalities within the framework of Delta calculus on time scales

AIMS Mathematics
Some new reverse versions of Hilbert-type inequalities are studied in this paper. The results are established by applying the time scale versions of reverse Hölder's inequality, reverse Jensen's inequality, chain rule on time scales, and the mean ...

On a Converse of Jensen's Discrete Inequality

Journal of Inequalities and Applications, 2009
We give the best possible global bounds for a form of discrete Jensen's inequality. By some examples the fruitfulness of this result is shown.

Stability of Jensen's equations in two normed spaces

Le Matematiche, 2002
Some stability questions of the Jensen's functional inequality in the setting of 2-normed spaces are derived in this article. Few more results are given on approximate isometries.
