In this paper, I develop a new method to test whether the introduction of competition policy in an industry has had any effects on its market performance. The method is based on the new empirical industrial organization methodology. I apply the method to the Turkish cement industry, which has...

This article evaluates the numerical accuracy of Ox object-oriented matrix programming language. It uses the Standard Reference Datasets (StRD) for estimation accuracy, the ELV DOS program for statistical distribution accuracy, and the DIEHARD battery of randomness tests for random number...

This paper replicates Cheung and Lai (1995), who use response surface analysis to obtain approximate finite-sample critical values adjusted for lag order and sample size for the augmented Dickey-Fuller test. We obtain results that are quite close to their results. We provide the Ox source code....

This paper replicates Leybourne et al. (1998), who propose a Dickey-Fuller type test for unit root that is most appropriate when there is reason to suspect the possibility of deterministic structural change in the series. We find that our replicated results are quite similar to the authors'...

This article reviews the object-oriented features of the Ox matrix programming language. We discuss object-oriented programming in general and give econometric examples coded in Ox. We also discuss some useful built-in classes that come with the Ox distribution.

This paper employs a new econometric technique to estimate the core inflation in Turkey measured as the shifting means in levels between 1955 and 2014. Using monthly series, we determine the number of shifts using the BIC, the hv-block cross-validation, the Lin-Teräsvirta parameter constancy...

In explaining economic phenomena, economic analysis concentrates on selected influences and fixes the host of other factors under a ceteris paribus clause. This view, which goes back to Alfred Marshall (1842-1924), is developed in the first part of the book. Aggregation is viewed as a particular...
