In this paper, Turkish high and persistent inflation experience and its impact on inflation uncertainty and growth have been investigated. GARCH models are used to generate a measure of inflation uncertainty and quarterly data covers the period of 1987:1-2003:3. According to the results from...

Although cross section relationships are often taken to indicate causation, and especially the important impact of economic growth on many social phenomena, they may, in fact, merely reflect historical experience, that is, similar leader-follower country patterns for variables that are causally...

This papers describes an estimator for a standard state-space model with coefficients generated by a random walk that is statistically superior to the Kalman filter as applied to this particular class of models. Two closely related estimators for the variances are introduced: A maximum...

The aggregation of individual random AR(1) models generally leads to an AR(∞∞) process. We provide two consistent estimators of aggregate dynamics based on either a parametric regression or a minimum distance approach for use when only macro data are available. Notably, both estimators allow...

I derive a generalized version of the fundamental law of active management under some weak conditions. I show that the original fundamental law of Grinold and various extensions are special cases of the result presented in this paper. I also show that cross-sectional ICs are usually different...

Bayesian inference requires an analyst to set priors. Setting the right prior is crucial for precise forecasts. This paper analyzes how optimal prior changes when an economy is hit by a recession. For this task, an autoregressive distributed lag model is chosen. The results show that a sharp...

A simple, empirical-based approach to decompose Realized Variance (RV) is proposed, with supportive theoretical argument and empirical evidence. Under the proposed framework, RV is interpreted as a product of the intensity and variance of relevant price changes. Holding the variance aspect...

Even with the presence of numerous institutional players in the market, there exist a noticeable number of cash group shares which are hardly transacted. To sustain the growth of investors in the market, there is need for assuring easy and quick liquidity to the securities. To serve the same...

In econometrics, long memory models for variance modeling like FIGARCH or FIAPARCH are characterized by a Fractional Differencing term. In order to estimate and apply these models, the infinite MacLaurin expansion of the differencing term has to be truncated at a certain level. We transfer the...
