عالمى معاشى افكار اور اسلامى معاشى فكر

This article aims to present a concise overview regarding global economic ideas and its historical development with brief evaluation of capitalism and communism as well as question of laissez-faire and concept of ownership in relation to Islamic economic thought. What are the rudiments, fundamentals and historical sketch of these systems? Measuring them analytically vis-à-vis their comparative examination has been taken into account to visit the characteristics of prevailing as well as outdated and nonoperational economic systems. As capitalism emphasis on eagerness to find wealth where billionaires are about to getting more and more ignoring various other ethical perspectives and paying no attention to the poor classes of society. Communism claiming equality remained also not compatible to sustain around the globe as a balanced and stable system. At the end this article predicts that other than Islamic economic thought no system may fulfill the natural need of global economy and it also recommends that Islamic Scholars have to present an alternative full-fledged practical model for economics.

Measurement Error and its Application in Survey Sampling

The present research is an effort to study the importance of measurement error in detail. The main aim of the study is to estimate the finite population mean in the presence of measurement error under non-response and randomized response while using simple and stratified random sampling schemes. We developed a generalized class of estimators by using dual use of auxiliary information in simple and stratified random sampling. Efficiency comparison is done theoretically and numerically. For numerical comparison both simulation study and real life data sets are used in this study. To gain the practical insight of measurement error, data is also collected and analyzed. In Chapters 2 and 3, the problem of measurement error and non-response in simple and stratified random sampling is studied. In Chapters 4 and 5, we discussed the estimation of finite population mean for sensitive variable in the presence of measurement error under simple and stratified random sampling. In Chapters 6 and 7, we studied those practical situations in which non-response and measurement error both occurs while estimating the finite population mean for sensitive variable, under simple and stratified random sampling, respectively. In Chapter 8, two stage cluster sampling for estimating the population mean in the presence of measurement error and non-response is studied.
