Thus we bound its logarithm variationally: ln S i ∈{0,1} exp j <k θ jk S j S k + j θ j0 S j = { j<k} =i θ jk S j S k + j =i θ j0 S j + ln S i ∈{0,1} exp j =i θ i j S i S j + θ i0 S i = { j<k} =i θ jk S ...
More formally, we have: (E step) : Q (k+1) = arg max Q L Q, θ (k) (48) (M step) : θ (k+1) = arg max θ L Q (k+1) , θ (49) which is coordinate ascent in L(Q, θ). ...

Applying the chain rule gives dL dW ij = ∂L ∂W ij + k ∂L ∂µ k ∂µ k ∂W ij + k ∂L ∂ξ k ∂ξ k ∂W ij , (3.16) where the last two terms account for the fact that the mean field parameters depend implicitly on ...
We can simplify this expression by noting that the mean field equations describe fixed points at which ∂L/∂µ k = ∂L/∂ξ k = 0; thus the last two terms in equation 3.16 vanish. ...

Corporate Bond Market Transparency and Transaction Costs
2004
Social Science Research Network
Using TRACE data-a complete record of all US OTC secondary trades in corporate bonds-we estimate average transaction cost as a function of trade size for each bond that traded more than nine times in 2003. We find that transaction costs are higher than in equities and decrease significantly with trade size. Highly rated bonds, recently issued bonds, and bonds that will soon mature have lower transaction costs than do other bonds. Costs are lower for bonds with publicly disseminated trade

Corporate Bond Market Transaction Costs and Transparency
2007
Journal of Finance
Using a complete record of U.S. OTC secondary trades in corporate bonds, we estimate average transaction costs as a function of trade size for each bond that traded more than nine times between January 2003 and January 2005. We find that transaction costs decrease significantly with trade size. Highly rated bonds, recently issued bonds, and bonds close to maturity have lower transaction costs than do other bonds. Costs are lower for bonds with transparent trade prices, and they drop when the
