This paper is a statistical time-series investigation addressed at testing the anthropogenic climate change hypothesis known as the “hockey-stick”. The time-series components of a select batch of 258 long-term yearly Climate Change Proxies (CCP) included in 19 paleoclimate datasets, all of...

This paper presents, discusses and tests a generalized Random Regret Minimization (G-RRM) model. The G-RRM model is created by replacing a fixed constant in the attribute-specific regret functions of the RRM model, by a regret-weight variable. Depending on the value of the regret-weights, the...

Systematic risk has been a focus for stress testing and risk capital assessment. Under the Vasicek asymptotic single risk factor model framework, entity default risk for a risk homogeneous portfolio divides into two parts: systematic and entity specific. While entity specific risk can be...

The Basel Accords have created the need to develop and implement models for PD, LGD and EAD. Although PD is quite well researched, LGD and EAD still lag both in theoretical and practical aspects. This paper proposes some empirical approaches for EAD/LGD modelling and provides technical insights...

This paper examines the demand for edible oil in Pakistan and a dynamic supply response model to show price responsiveness by sunflower oilseed farmers. The demand for edible oil is estimated by using Ordinary Least Square (OLS) technique. It has been found that an increase in the consumption of...

The transition density of a diffusion process does not admit an explicit expression in general, which prevents the full maximum likelihood estimation (MLE) based on discretely observed sample paths. Aït-Sahalia [J. Finance 54 (1999) 1361–1395; Econometrica 70 (2002) 223–262] proposed asymptotic...

This paper examines the impact of minimum wages on average wage earnings in two selected countries, Trinidad and Tobago and Jamaica using a time-series data for the latter and a panel data for both. The methodology of GMM time-series estimation is used on the Jamaican data (1980-2011) and a Two...

The importance of studying demand for bank loan by private business sector stems from the fact the money supply is ‘credit-driven’ and demand-determined and at the rate of interest determined by the central bank the money supply function is horizontal as illustrated by Moore and Threadgold...

A manual is designed to support and help the basic concepts of statistics and its implications in econometric, beside this, interpretation of further statistical techniques have been shown as well by illustrations and graphical methods. It is comprised on several instances of test, obtained from...

This paper considers the problem of parameter estimation in a general class of semiparametric models when observations are subject to missingness at random. The semiparametric models allow for estimating functions that are non-smooth with respect to the parameter. We propose a nonparametric...
