Multicollinearity hampers empirical econometrics. The remedies proposed to date suffer from pitfalls of their own. The ridge estimator is not generally accepted as a vital alternative to the ordinary least-squares (OLS) estimator because it depends upon unknown parameters. The generalized...

We consider testing the null hypothesis of no spatial autocorrelation against the alternative of first order spatial autoregression. A Wald test statistic has good first order asymptotic properties, but these may not be relevant in small or moderate-sized samples, especially as (depending on...

This study investigates the relationship of income inequality (proxied by the Gini Coefficient), labor productivity (output per capita) on fertility rate in the Philippines. Specifically, this presents the trend of income inequality (ineq), labor productivity (lp) and fertility(tfr) in the...

This paper has been designed to investigate whether health accelerate economic growth in Pakistan. The study is using Growth Accounting Method, Ordinary Least Squares and Johansen Cointegration Test as analytical techniques. The Growth Accounting Method shows that Total Factor Productivity,...

Agriculture is considered as the backbone of Pakistan’s economy and a reasonable proportion of population is engaged in it. The present study aims at finding the role of education in productivity of wheat, sugarcane and tobacco crops in Khyber Pakhtunkhwa (KPK) during the period 1975-2008. The...

In this paper I provide new evidence on the implications of treatment effect heterogeneity for least squares estimation when the effects are inappropriately assumed to be homogenous. I prove that under a set of benchmark assumptions linear regression provides a consistent estimator of the...

This paper examines the role of bank ownership structure on capital structure by [using the financial and ownership data from Caprio et al. (2007) that covered 244 banks across 44 countries]. We classified banks across the countries with geographical regional dummies indicating if the banks are...

This paper concentrates on the contribution of education to economic growth of Pakistan during 1971-2008.The study uses Ordinary Least Squares (OLS) and Johansen Cointegration test as analytical techniques for this purpose. The results from OLS show that secondary education contributes...
