During the last decades many financial analysts, either theorists or practitioners, have dedicated their studies to the interactions between different financial sectors. The results of these researches confirm that commodities, bonds and stock markets are closely related, therefore a thorough...

Проаналізовано довгостроковий тренд впливу іноземних фондових бірж на динаміку українського фондового ринку, зокрема на динаміку його організованого сегменту...

Since times of Yule (1926), it is known that correlation between two time series can produce spurious results. Granger and Newbold (1974) see the roots of spurious correlation in non-stationarity of the time series. However the study of Granger, Hyung and Jeon (2001) prove that spurious...

This paper aims to answer the question if and how much the foreign investors influence the boom and bust of small stock exchanges. It examines the impact of the foreign investors’ turnover towards small stock exchange turnover, particularly the Macedonian Stock Exchange. Based on the...

In this paper I provide new evidence on the implications of treatment effect heterogeneity for least squares estimation when the effects are inappropriately assumed to be homogenous. I prove that under a set of benchmark assumptions linear regression provides a consistent estimator of the...

We discuss linear regression approaches to conditional Value-at-Risk and Average Value-at-Risk (Conditional Value-at-Risk, Expected Shortfall) risk measures. Two estimation procedures are considered for each conditional risk measure, one is direct and the other is based on residual analysis of...

The most part of the paper is about modeling (or approximating) nonstochastic regressors. Examples of regressors which are (not) L2-approximable are given. Applications to central limit theory and OLS estimator asymptotics are provided.

The National Basketball Association claims to sell entertainment. Part of that entertainment is close, competitive contests with uncertain outcomes. However, hometown fans want the home team to win.

In this study we investigated several most popular Loss Given Default (LGD) models (LSM, Tobit, Three-Tiered Tobit, Beta Regression, Inflated Beta Regression, Censored Gamma Regression) in order to compare their performance. We show that for a given input data set, the quality of the model...

We consider inference post-model-selection in linear regression. In this setting, Berk et al.(2013) recently introduced a class of confidence sets, the so-called PoSI intervals, that cover a certain non-standard quantity of interest with a user-specified minimal coverage probability,...
