This paper reviewed some of the debate among researchers about usefulness of econometric models and doubts surrounding their use. Economists and policy makers frequently uses econometric model to forecasts the effects of choosing one policy or another. Despite the severe criticism made against...

Logarithmic spirals are abundantly observed in nature. Gastropods (such as nautilus, cowie, grove snail, thatcher, etc.) in the mollusca phylum have spiral shells, mostly exhibiting logarithmic spirals vividly. Spider webs show a similar pattern. The low-pressure area over Iceland and the...

We develop simple and non-asymptotically justified methods for hypothesis testing about the coefficients ($\theta^{*}\in\mathbb{R}^{p}$) in the high dimensional generalized regression models where $p$ can exceed the sample size. Given a function $h:\,\mathbb{R}^{p}\mapsto\mathbb{R}^{m}$, we...

This paper re-investigates unit root hypotheses in inflation rates for 21 OECD countries using the newly proposed GARCH-based unit root tests with structural break and trend specifications. The results showed that classical tests over-accept unit roots in inflation rates, whereas these tests are...

This paper highlights and demonstrates the technical and economical impact of technical textiles in the industrially developed countries and their future contribution to the development of economics of newly developing countries, such as China, South East Asia, and North Africa etc. Pakistan...

We develop simple and non-asymptotically justified methods for hypothesis testing about the coefficients ($\theta^{*}\in\mathbb{R}^{p}$) in the high dimensional (generalized) regression models where $p$ can exceed the sample size $n$. Given a function $h:\,\mathbb{R}^{p}\mapsto\mathbb{R}^{m}$,...

In this paper we show that survey-based-expectations about the future evolution of the Chilean exchange rate have the ability to predict the returns of the six primary non-ferrous metals: aluminum, copper, lead, nickel, tin and zinc. Predictability is also found for returns of the London Metal...

This paper combines historical cross-sectional and longitudinal income and wealth data in the United States to present the evolution of absolute intragenerational mobility from the 1960s onward. That is, the fraction of families with higher income or wealth over a given period. We find that the...

Existing literature has overstressed the importance of exogenous constraints in the economic performance of African countries at the expense of endogenous constraints, although the latter are longer-lasting and more self-propagating than the former. In this exploratory essay I put endogenous...

Inequality is a problem that has been raising over time, generating high economic and social costs. In this sense, the present investigation evaluated the nexus between globalization and inequality for 104 countries classified by their income level using a Econometric study during 1995-2018. For...
