In this paper, we argue that study of the effect of financial development and shocks on aggregate growth volatility will not be informative because they affect growth volatility through its different components. Financial development affects only the business cycle component of volatility and therefore, the effect on total volatility is dependent on its share in total volatility. On the contrar...

investing in stock markets usually is involved in more risks than the bounds and bank deposits. it is expected that resulting returns (capital gain plus yields) from trading in a stock market to be more than those of in a risk free investment. therefore, developing accurate techniques of estimation and forecasting in volatility analysis of financial markets is inevitable. sum squares of weekly ...

iranian banks can not freely determine their interest rates in the financial market. this characteristic causes banking industry unable to perform their duties of financial intermediaries in the transmission mechanism of monetary. in these circumstances, monetary shocks will have a significant and high effect on the alternative markets (like stocks and housing). in this study, we used dynamic s...

Several researchers have recently documented a large reduction in output volatility. In contrast, this paper examines whether output has become more predictable. Using forecasts from the Federal Reserve Greenbooks, I find the evidence is somewhat mixed. Output seems to have become more predictable at short horizons, but not necessarily at longer horizons. The reduction in unpredictability is mu...

This theoretical note aims at studying the role of reference points in generating unemployment volatility. For this purpose, I introduce the notion of reference points in a standard Mortensen-Pissarides model. I obtain two results. First, I find that the obtained model is similar to the one found by Pissarides (2009). Second, I show that the introduction of reference points can increase signifi...

In this paper we study the effect of contemporaneous aggregation of an arbitrarily large number of processes featuring dynamic conditional heteroskedasticity with short memory when heterogeneity across units is allowed for. We look at the memory properties of the limit aggregate. General, necessary, conditions for long memory are derived. More specific results relative to certain stochastic vol...

This paper assesses the day of the week effect of the daily depreciation of the Turkish lira (TL) against the US dollar (USD) and its volatility. The empirical evidence from Turkey presented here suggests that Thursdays are associated with higher and Mondays with lower depreciation rates compared to those of Wednesdays. Moreover, Mondays and Tuesdays are associated with higher volatility than W...

Stock market crashes are traumatic events that affect the lives of millions of people around the globe and have tremendous economic implications. Crashes are not only dramatic, but often completely unexpected. The 1987 crash, for example, was not induced by any obvious trigger. Even after the fact, it is hard to find the reason for the crash – Why did the market crash in October rather than in ...

 As the number of independent countries increases and their economies become more integrated, we would expect to observe more multi-country currency :::union:::s. This paper explores the pros and cons for different countries to adopt as an anchor the US Dollar, the Euro or the Yen. In addition, it addresses the question of how co-movement of outputs and prices would respond to the formation of ...

We propose and test the idea that investor perceptions exhibit volatility ‘after-effects’ whereby perceived volatility is distorted after prolonged exposure to extreme volatility levels. Using VIX to measure perceived volatility in S&P 500 stocks, we find evidence of significant perceptual distortions in the aftermath of volatility regimes, consistent with the after-effect theory and recent exp...
