Upward and downward statistical continuities

A real valued function $f$ defined on a subset $E$ of $\textbf{R}$, the set of real numbers, is statistically upward continuous if it preserves statistically upward half quasi-Cauchy sequences, is statistically downward continuous if it preserves statistically downward half quasi-Cauchy sequences; and a subset $E$ of $\textbf{R}$, is statistically upward compact if any sequence of points in $E$ has a statistically upward half quasi-Cauchy subsequence, is statistically downward compact if any sequence of points in $E$ has a statistically downward half quasi-Cauchy subsequence where a sequence $(x_{n})$ of points in $\textbf{R}$ is called statistically upward half quasi-Cauchy if $$\lim_{n\rightarrow\infty}\frac{1}{n}|\{k\leq n: x_{k}-x_{k+1}\geq \varepsilon\}|=0$$ is statistically downward half quasi-Cauchy if $$\lim_{n\rightarrow\infty}\frac{1}{n}|\{k\leq n: x_{k+1}-x_{k}\geq \varepsilon\}|=0$$ for every $\varepsilon>0$. We investigate statistically upward continuity, statistically downward continuity, statistically upward half compactness, statistically downward half compactness and prove interesting theorems. It turns out that uniform limit of a sequence of statistically upward continuous functions is statistically upward continuous, and uniform limit of a sequence of statistically downward continuous functions is statistically downward continuous.Comment: 25 pages. arXiv admin note: substantial text overlap with arXiv:1205.3674, arXiv:1103.1230, arXiv:1102.1531, arXiv:1305.069

Consumption Patterns of Major Food Items in Turkey

Demand estimates for food not only provide information bases to characterise food demand structure, but also provide a complete and consistent framework to evaluate the impacts of policy changes, since both price policies and the human capital policies related to health and nutrition are closely related to the determination of expenditure (or income) elasticities. This study attempts to produce a complete set of expenditure and price elasticities based on the estimates of food demand parameters in Turkey. The Linear Expenditure System (LES) is estimated using the last available cross-section budget survey data. The estimates throw light on certain characteristics of Turkish household behaviour that has some consequences for government policies.

Dynamic Interdependence and Volatility Transmission in Turkish and European Equity Markets

This paper investigates dynamic interdependence, price and volatility transmissions and financial integration between Turkey and major equity markets in EU and USA. We attempt to quantify the dynamic relationship among developed stock exchanges of Germany, France, Britain, US and Turkey, an important emerging market. Using daily data on stock prices we analyze price and volatility spillovers in a vector autoregression-dynamic conditional correlations-multivariate generalized autoregressive conditional heteroskedacticity (VAR-DCC-MVGARCH) framework. This approach enables us to measure the extent to which these equity markets are interrelated by taking into account the time-varying variance-covariance structure. Since the major trade partners of Turkey are EU countries it is of interest to examine any changes in the structure of volatility spillovers. To this end, we analyze the effects of customs union agreement between Turkey and EU on the dynamic interdependence of stock markets by dividing the sample into two periods. The analysis reveals that, although they are small in magnitude as compared to their counterparts in developed markets, the conditional correlations can be assumed to be constant in the pre-customs union agreement while it fluctuates significantly in the post-customs union agreement.
