The was conducted using VOSViewer software. data analyzed were form scientific related economics Islamic countries as many 45 articles last 10 years. results showed that number publications on continued incre...

This paper tries to analyze effects of trade and financial liberalizations on the Iran’s government size during both long-run and short- run. Accordingly, a specification of the auto regression with distributed lag (ARDL) has been used for investigating the long run relationships between variables, and a vector correction model (VECM) has examined dynamically the short-run relationships betwe...

The aim of this paper is to empirically investigate the effect of Intellectual Capital (IC) and its components on financial performance of Iranian banks accepted in Tehran Stock Exchange (TSE). The financial performances were measured by return on equity (ROE), return on assets (ROA), assets turnover (ATO), and book to market ratio (MB). This research covers 14 banks listed in TSE over the peri...

General Equilibrium asset pricing models have a difficult time simultaneously delivering a sizable equity premium, a low and counter-cyclical real risk free rate, as well as cyclical variation in return volatility. To explain these stylized facts, this paper introduces occasionally binding financing constraints that impede producers’ ability to invest in an otherwise standard real business cycl...

Labor Market Institutions, Wages, and Investment Labor market institutions, via their effect on the wage structure, affect the investment decisions of firms in labor markets with frictions. This observation helps explain rising wage inequality in the US, but a relatively stable wage structure in Europe in the 1980s. These different trends are the result of different investment decisions by firm...

In this paper we use panel data on …rms from Brazil and China to investigate the role of …nancial constraints for borrowing and investment. We develop a structural investment model, in which borrowing is costly but sometimes necessary to …nance investment. Structural parameters are estimated by matching simulated model moments to empirical data, using a simulated minimum distance estimator. The...

Optical characterization of DNA-wrapped CoMoCAT carbon nanotube hybrids (DNA–CNT) and semiconductor-enriched DNA–CNT was carried out using resonant Raman spectroscopy (RRS) and photoluminescence (PL) experiments. The values of radial breathing modes frequency xRBM were found to be relatively insensitive to the type of wrapping agents surrounding the nanotube. The values of xRBM and the first an...

It is a well documented empirical fact that …rm level investment is lumpy rather than smooth. In the present paper we …nd that the aggregate consequences of lumpy investment in general equilibrium are quantitatively important. Earlier results stressing the irrelevance of lumpy investment in general equilibrium are therefore an artefact of assuming perfect competition combined with fully ‡exible...

The paper investigates the impact on credit risk of capital structure choices driven by firm’s investments and financing decisions. We propose a realistic dynamic structural model featuring endogenous investment, capital structure and default. We calibrate the model on accounting and market data. Using simulation, we find that, credit spreads as well as other standard metrics of credit worthine...

Like other macroeconomic variables, residential investment has become much less volatile since the mid-1980s (recent experience notwithstanding.) This paper explores the role of structural change in this decline. Since the the early 1980s there have been many changes in the underlying structure of the economy, including those in the mortgage market which have made it easier to acquire a home. W...
