The negative relationship between market P/E ratios and government bond yields seems to have become conventional wisdom among practitioners. Both (limited) empirical evidence and a (misleading) suggestion that the model originated in the Fed are used to support the model’s plausibility. The evidence in this note, from 20 international markets, seriously questions the wide acceptance and use of ...

We present a unified model of infrared (IR), optical, ultraviolet (UV), and X-ray light curves for the 1983 outburst of GQ Muscae (Nova Muscae 1983) and estimate its white dwarf (WD) mass. Based on an optically thick wind model of nova outbursts, we model the optical and IR light curves with free-free emission, and the UV 1455 Å and supersoft X-ray light curves with blackbody emission. The best...

In the U.S. business income is taxed several times at different sources, including corporate income, dividends, capital gains, and interest payments. We investigate how the different rates above affect firm investment and the allocation of capital in the economy. To do so, we construct and calibrate a model with heterogeneous firms, borrowing constraints, costly equity issuance and endogenous e...

This paper is devoted to research the validity of options strategies with a particular emphasis on weekly options. The author proves that options, when traded successfully, could be better substitute than buying or selling underlying and good given volatility strategy well capitalised stocks give superb results. analysed simple using moving average bollinger bands US market.

Incentive problems make securities’ payoffs imperfectly pledgeable, limiting agents’ ability to issue liabilities. We analyze the equilibrium consequences of such endogenous incompleteness in a dynamic exchange economy. Because markets are endogenously incomplete, agents have different intertemporal marginal rates substitution, so that they value assets differently. Consequently, hold portfolio...

The aquatic sex pheromone splendipherin (GLVSSIGKALGGLLADVVKSKGQPA-OH) of the male green tree frog Litoria splendida moves across the surface of water to reach the female. Surface pressure and X-ray reflectometry measurements confirm that splendipherin is a surface-active molecule, and are consistent with it having an ordered structure, whereby the hydrophilic portion of the peptide interacts w...
