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...

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 developing countries. The performance of the VaR is assessed by both unconditional and conditional tests of Kupiec and Christoffersen, respectively, as well as the...

Applied econometric work takes a superficial approach to causality. Understanding economic affairs, making good policy decisions, and progress in the economic discipline depend on our ability to infer causal relations from data. We review the dominant approaches to causality in econometrics, and...

The argument that modern economies cannot function without interest is examined in detail. We show that Islamic alternatives to interest, which vary with the context and the type of loan, provide adequate substitutes. Interest based institutions lead to many types of difficulties both practical...

A traditional Islamic education develops an Islamic outlook to life but does not prepare the student assimilate developments over the past three or four centuries, in particular Western knowledge. A modern Western education inevitably entails absorption of a secular worldview built into the...

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...

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...

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.
