We introduce a simple generalization of rational bubble models which removes the fundamental problem discovered by [20] that the distribution of returns is a power law with exponent less than 1, in contradiction with empirical data. The idea is that the price fluctuations associated with bubbles must on average grow with the mean market return r. When r is larger than the discount rate rδ , the...

In Recent Decades, The Financial Sphere has entered a New Era of Contempt for Some of the Assumptions of Modern Economics and Finance. One of These Assumptions is the Rationale of the Investors, which has been Seriously Challenged and Is Now Being Strengthened by the Fact That Prices are Determined more by Attitudes and Psychological Factors than for Fundamental Variables and Therefore the Stud...

abstract present study used translog cost function for determining break point of paddy farms. requested data set include inputs’ prices and quantities, and production amounts had been acquired from 500 rice farmers of guilan province at 2009. model used in this study is seemingly unrelated regressions (sur). the results showed that labor and pesticides had the highest and lowest share of produ...

The cross-section of returns of stock portfolios sorted along the book-to-market dimension can be understood with a one-factor model. The factor is the nominal bond risk premium, best measured as the Cochrane-Piazzesi (2005, CP) factor. This paper ties the pricing of stocks in the cross-section to the pricing of government bonds of various maturities, two literatures that have been developed la...

This paper describes the Itô processes for the continuously compounded returns on European call and put stock options under the one-dimensional diffusion assumption and the Black Scholes pricing model. It uses the Itô processes to motivate discrete time approximations for the returns on calls and puts. Theses models are used in a simulation study to compute the probability of an option return v...

The purpose of this study is to determine the effect Return on Assets (ROA), Equity (ROE), Earning per Share (EPS), and Price Book Value (PBV) stock prices returns in manufacturing companies registered Indonesia Stock Exchange 2018-2020. This used 73 as sample using panel data regression analysis. results indicate that ROA has negative insignificant prices, positive significant returns; ROE EPS...

This paper investigates the rank distribution, cumulative probability, and probability density of price returns for the stocks traded in the KSE and the KOSDAQ market. This research demonstrates that the rank distribution is consistent approximately with the Zipf’s law with exponent α = −1.00 (KSE) and −1.31 (KOSDAQ), similar to that of stock prices traded on the TSE. In addition, the cumulativ...

We shortly review the statistical properties of the escape times, or hitting times, for stock price returns by using different models which describe the stock market evolution. We compare the probability function (PF) of these escape times with that obtained from real market data. Afterwards we analyze in detail the effect both of noise and different initial conditions on the escape time in a m...

We investigate the fluctuation behaviors of financial stock markets by Zipf analysis. In the present paper, the empirical research is made to describe ensembles and specifics of stock price returns for global stock indices, and the corresponding Zipf distributions are given. First we study the fluctuation behavior of global stock markets by m, k -Zipf method. Then we consider a dynamic stock pr...

This paper investigates the relationship between aggregate stock market trading volume and the serial correlation of daily stock returns. For both stock indexes and individual large stocks, the first-order daily return autocorrelation tends to decline with volume. The paper explains this phenomenon using a model in which risk-averse "market makers" accommodate buying or selling pressure from "l...
