A literature search shows that robust regression techniques are rarely used in applied econometrics. We present a technique based on Rousseeuw and Van Zomeren (Journal of the American Statistical Association, 85 (1990) 633–639) that removes many of the difficulties in applying such techniques...

This study compares the performance of the widely used risk measure Value-at-Risk (VaR) across a large sample of developed and emerging countries. The performance of the VaR is assessed by both unconditional and conditional tests of Kupiec and Christoffersen, respectively, as well as the...

The objective of this article is to investigate the effect of government expenditure on GDP in Turkey from 2000Q1-2015Q4 by the superexogeneity test. As a consequence of satisfying both conditions of weak exogeneity and structural invariance, government expenditure is super exogenous to GDP...

The systematic risk of IPO’s in the thinly traded Istanbul Stock Exchange (ISE) are estimated using Empirical Bayes Estimators (EBE). The sectors that the firms belong to, provide the priors. Comparisons are made with OLS estimators across different estimation and forecasting periods. Two...
