On the cohomology of moduli spaces of (weighted) stable rational curves

We give a recursive algorithm for computing the character of the cohomology of the moduli space \Mmb_{0,n} of stable $n$-pointed genus zero curves as a representation of the symmetric group \Sg_n on $n$ letters. Using the algorithm we can show a formula for the maximum length of this character. Our main tool is connected to the moduli spaces of weighted stable curves introduced by Hassett.Comment: Version 2: Several small changes. Details added in the proof of Theorem 5.1.

A comparative analysis of Keynesian and Swedish theory of economic fluctuations

The purpose of this study is to examine critically both Keynesian and Swedish theories of economic fluctuations. It is a well known fact that in Sweden K. Wicksell was very skeptical about Say\u27s law. With his skepticism, Wicksell occupied a position close to Keynes\u27 General Theory. However, Wicksell could not present a convincing theory of the existence of general unemployment, because he did not observe the downward rigidity of wages or the Keynesian liquidity trap
