the purpose of this research is investigation of application of the arbitrage pricing theory and effect of unanticipated changes in a set of macroeconomic variables such as inflation rate, money supply, exchange rate, oil price, term structure and industrial production on expected security return in tehran stock exchange. in this research, data are analyzed quarterly for the period of 1997-2008...

Context. The source of emission from Sgr A*, the supermassive black hole at the Galactic Center, is still unknown. Flares and data from multiwavelength campaigns provide important clues about the nature of Sgr A* itself. Aims. Here we attempt to constrain the physical origin of the broadband emission and the radio flares from Sgr A*. Methods. We developed a time-dependent jet model, which for t...

This paper evaluates a novel sampling algorithm, called shotgun stochastic search (S3), for Bayesian model averaging in the context of finding predictors for inflation when the set of potential predictors is large. This is a relevant case in the forecasting literature, where often hundreds of predictors are compared with autoregressive distributed lag models for inflation. With such a large mod...

The objective of this study is to test the relationship between short-term nominal interest rate and inflation in the context of the Indian financial market. To achieve this objective we perform Augmented Dickey-Fuller unit root test to check for stationarity and thereafter we test for co-integration using the Engle-Granger method and further corroborate the findings of this test with the Johan...

concept of inflation compensation. Finally, we provide evidence that Federal Reserve communication and surprises in monetary policy actions bear on the uncertainty surrounding the expected rate of inflation. For one concept of inflation expectations, we find that Federal Reserve communication reduces uncertainty about the future rate of inflation, while surprises in monetary policy actions incr...

This article examines public opinion in advanced economies to assess what the general public thinks about inflation. Are individual citizens concerned about inflation? How important a public policy issue do they think it is? What influences their opinions about inflation? Does opinion about inflation vary across countries and, if so, what accounts for this variation? The opinion surveys examine...

investing in research and development spending (r&d) affects total factor productivity (tfp).recently new theories of economic growth have emphasized the relationship between r&d and tfpand also identified a number of channels through which a country’s r&d affects tfp of its tradepartner. this study seeks to estimate the effect of agricultural r&d and education spending and some...

the purpose of this paper is to examine the effects of monetary, fiscal and oil revenue shocks on macroeconomic variables in the framework of rule and discretionary monetary policy. to end this, we use a new keynesian dynamic stochastic general equilibrium (dsge) model. given the dominant role of oil in the country, we consider the role of oil shock in the model through different channels. the ...
