there are two main reasons for studying investment in an economy. first, the combination of firms? investment demand and household?s saving supply determines how much of an economys? resoures is invested. second, investment is highly volatile; thus investment demand may be important in the short-run fluctuations. the present article examins the relationship and veracity of existence of banks pr...

by the advent and development of information and communication technology (ict), the micro and macro economic variables are changed. in other words, the exclusive characteristics of ict can alter the job framework in a society. this fact will be done in our country, too. because of the importance of the employment issue in iran, a research in about of effect of ict on this variable in iran is s...

This paper investigates the e¤ects of replacing the consumer price index (CPI) with the wholesale price index (WPI) in the cointegrating international parity relationships found by Juselius and MacDonald (2000). Our empirical analysis outstandingly produced results similar to the ones obtained by Juselius and MacDonald, suggesting that the cointegration relationships in the international parity...

The data in Fehr and Tyran (2001) and Petersen and Winn (2014) show that money illusion plays an important role in nominal price adjustment after a fully anticipated negative monetary shock. Money illusion affects subjects’ expectations, and causes pronounced nominal inertia after a negative shock but much less inertia after a positive shock. Thus Petersen and Winn (2014) provide a misleading i...

– This paper applies neural network methodology to inßation forecasting in the Euro-area and the USA. Neural network methodology outperforms linear forecasting methods for the Euro Area at forecast horizons of one, three, and six month horizons, while the linear model is preferable for US data. The nonlinear estimation shows that unemployment is a signiÞcant predictor of inßation for the Euro A...

In this paper we apply the wavelets methodology to the analysis of the comovements of for some MENA countries from June 1997 until March 2005. We decompose weekly stock market returns into di¤erent time scale components using the non-decimated discrete wavelet transform and then analyze the relationships among these variables at the di¤erent time scales. Keywords : Stock market returns, Wavelet...

We re-examine the empirical relevance of the cost channel of monetary policy (e.g. Ravenna andWalsh, 2006), employing recently developed moment-conditions inference methods, including identi…cation-robust procedures. Using US data, our results suggest that the cost channel e¤ect is poorly identi…ed and we are thus unable to corroborate the previous results in the literature. Keywords: Cost chan...

We build a model in which the Fed and market disagree about future aggregate demand. The anticipates monetary policy “mistakes,” affect current demand induce to partially accommodate market’s view. expects implement its view gradually. Announcements that reveal an unexpected change Fed’s belief provide microfoundation for shocks. Tantrum shocks arise when misinterprets overreacts announcement. ...

We examine robustness of stability under learning to observability of exogenous shocks. Regardless of observability assumptions, the minimal state variable solution is robustly stable under learning provided the expectational feedback is not both positive and large, while the nonfundamental solution is never robustly stable. Overlapping generations and New Keynesian models are considered and co...

In this paper, we re-examine the empirical relevance of the cost channel of monetary policy. We employ recently developed moment-conditions inference procedures, which provide a more e¢ cient and reliable econometric framework than in previous literature. Using US data, our results suggest that there is no substantial evidence for the existence of a cost channel. Keywords: Cost channel; Phillip...
