An information transaction entails the purchase of information. Formally, it consists of an information structure together with a price. We develop an index of the appeal of information transactions, which is derived as a dual to the agent’s preferences for information. The index of information transactions has a simple analytic characterization in terms of the relative entropy from priors to p...

This note explores the link between anticipated information and a preference for liquidity in investment choices. Given a subjective ordering of investment portfolios by their liquidity, we identify a sufficient condition under which the prospect of finer resolution of uncertainty creates a preference for more liquid positions. We then show how this condition might arise naturally in some stand...

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...
