We study a model with repeated moral hazard where financial contracts are not fully indexed to inflation because nominal prices are observed with delay, as in Jovanovic & Ueda (1997). More constrained firms sign contracts that are less indexed to inflation, and as a result, their investment is more sensitive to nominal price shocks. We also find that the overall degree of nominal indexation inc...

Let D be a division ring with centre K and dim, D< ? a valuation on K and v a noninvariant extension of ? to D. We define the initial ramfication index of v over ?, ?(v/ ?) .Let A be a valuation ring of o with maximal ideal m, and v , v ,…, v noninvariant extensions of w to D with valuation rings A , A ,…, A . If B= A , it is shown that the following conditions are equivalent: (i) B i...

This paper studies the application of an inverse methodology for problem solving in fracture mechanics using the finite element analysis. The method was applied to both detection of subsurface cracks and the study of propagating cracks. The procedure for detection of subsurface cracks uses a first order optimization analysis coupled with a penalty function to solve for the unknown geometric par...

Reversed-phase high-performance liquid chromatography (RP-HPLC) has been carried out for a series of unsubstituted polycyclic aromatic hydrocarbons (PAHs) and the corresponding ethynyl, 1,3-butadiynyl, and 1,3,5-hexatriynyl derivatives. Theoretical values of the isotropic polarizability and several polarity descriptors have been computed for each compound by using semiempirical models and densi...

In light of WMAP results, we examine the observational constraint on the P-term inflation. With the tunable parameter f , P-term inflation contains richer physics than D-term and F-term inflationary models. We find the logarithmic derivative spectral index with n > 1 on large scales and n < 1 on small scales in agreement to observation. We obtained a reasonable range for the choice of the gauge...
