in last 1990 decade and early 21 century due to high fluctuations in assets prices and occurring asset price bubbles, most studies in monetary economics has concentrated on the reaction of monetary policy to movement in asset prices. the purpose of this paper is to analyze the suitable reaction of monetary policy to movement in asset prices in iran. this analysis is based on the structural var ...

Inspecting financial markets from a complex network perspective means to extract relationships and interdependencies from stock price time series. Correlation networks have been shown to adequately capture such dependence structures between financial assets. Moreover, researchers have observed modifications in the correlation structure between stock prices in the face of a market turbulence. Th...

This section describes a simplified version of the dynamic IS − LM model in Blanchard (1981), that extends this elementary macroeconomic scheme along two dimensions: (i) by considering dynamics, and (ii) by enlarging the set of financial markets beyond the traditional "money" and "bonds". In the model below, the latter extension is limited to the stock market. Stock prices have a forward-lookin...

In financial markets such as Tehran Stock Exchange, P/E coefficient, which is one of the most well-known instruments for evaluating stock prices in financial markets, is considered necessary for shareholders, investors, analysts and corporate executives. P/E is used as an important indicator in investment decisions. In this research, harmony search metaheuristic algorithm is used to select opti...

the current study addresses an estimation of investor's optimal portfolio under conditions of uncertainty by using a combination of artificial neural network and markowitz models. for this purpose, such assets as stock prices, house prices, coin and bonds price are used with monthly data over the period 1378-1392. three variables including inflation uncertainty, oil uncertainty and free ma...

The idea of investigating the relation of option and stock prices based just on the no-arbitrage assumption, but without assuming any model for the underlying price dynamics, has a long history in the financial economics literature. We introduce convex and, in particular semidefinite optimization methods, duality, and complexity theory to shed new light on this relation. For the single stock pr...

Thomas A. Rietz (1988) proposes that the possibility of rare disasters (such as economic depressions or wars) is a major determinant of asset risk premia. Robert J. Barro (2006) shows that, internationally, disasters have been sufficiently frequent and large enough to make the Rietz proposal viable, and they account for a high equity premium. The Rietz-Barro hypothesis is almost always formulat...
