This paper evaluates the current competition policy framework in Turkey. A brief history of competition policy is presented. An account of the Law on the Protection of Competition, the main law on competition in Turkey, is given. The structure of the Competition Authority, the body responsi- ble...

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 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 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 specifies, estimates, and evaluates the relation between inflation rate and excess money growth, defined as the difference between money supply growth and real GDP growth, using a smooth transition regression model and U.S. data. The results indicate that the relation is a nonlinear...

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 note demonstrates how performance measure congruity and noise determine an agency’s total surplus within an linear agency framework with multiple tasks. It provides a decomposition of agency costs, leading back to a congruity index previously proposed in the literature. In addition,...
