Statistical offices try to match item models when measuring inflation between two periods. However, for product areas with a high turnover of differentiated models, the use of hedonic indexes is more appropriate since they include the prices and quantities of unmatched new and old models. The...

This paper aims to assess the degree of students’ interest in mathematics and statistics. Five universities, having Engineering and technology education in Sindh Province, have been taken as targeted population. Non-parametric test Statistic X2 at X = 0.05 on collected categorical data has...

Calibration of multidimensional economic problems proven to be difficult, as there is a high risk of problem miss-identification. In this paper we propose a multistage calibration method to estimate the six parameters of a commodity market price model that includes storage. We assume that the...

The COVID-19 pandemic and the resulting public health mitigation have caused large-scale economic disruptions globally. During this time, there is an increased need to predict the macroeconomy's short-term dynamics to ensure the effective implementation of fiscal and monetary policy. However,...

We introduce a structural vector autoregressive (SVAR) model with each of the mutually independent errors following a skewed generalized t-distribution that is more flexible than a Student's t-distribution typically considered. Hence, the effect of potential distributional misspecification is...

Policy makers depend on economists, statisticians, and other social scientists to make accurate observations and draw solid conclusions from quantitative analysis. Econometrics, for example, has come a long way in the past century and guides many decisions made today. On the other hand, some...
