In this paper we highlight the necessity of new criteria for evaluation of performance of unit root tests. We suggest focusing directly on the reasons that create ambiguity in unit root test’s results. Two reasons for unsatisfactory properties of unit root tests can be found in the literature...

We study the test for location parameter of a random number from Cauchy density, focusing on point optimal tests. We develop analytical technique to compute critical values and power curve of a point optimal test. We study the power properties of various point optimal tests. The problem turned...

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...

While the strategy of measuring and quantifying has been extremely successful, and valuable in the progress of science, it does not follow that it is universally useful. We argue that attempts to measure corruption can be counterproductive in several different ways. Qualitative and action...

Performance of unit tests depends on several specification decisions prior to their application e.g., whether or not to include a deterministic trend. Since there is no standard procedure for making such decisions, therefore the practitioners routinely make several arbitrary specification...

The elevation of scarcity to the fundamental economic problem rests on some unstated normative assumptions. These include a political commitment to private property, a methodological commitment to not inquire about taste formation, and the idea that human welfare is roughly equivalent to...

How do we arrest the decline of the social sciences in Pakistan? Is it a matter of money or one of sending more students to the West who might then return to teaching at the local universities? In this article I argue that the solution lies elsewhere. Borrowing frames, concepts, and analytical...

This paper illustrates on a simple model of production economy how the concept of partial equilibrium can be in an unresolvable conflict with the general equilibrium.

There is a conflict in the mechanism for price determination used in a Marshallian partial equilibrium supply and demand framework and the Walrasian general equilibrium framework. It is generally thought that partial equilibrium is a simplified approximation to the complexities of the general...

Econometric Methodology is based on logical positivist principles. Since logical positivism has collapsed, it is necessary to re-think these foundations. We show that positivist methodology has led econometricians to a meaningless search for patterns in the data. An alternative methodology which...
