This paper examines the application of the Least Absolute Deviations (LAD) method for ridge-type parameter estimation of Seemingly Unrelated Regression Equations (SURE) models. The methodology is aimed to deal with the SURE models with non-Gaussian error terms and highly collinear predictors in...

The choice of capital budgeting methods used by companies listed on the Stockholm Stock Exchange (SSE) is examined using multivariate regression analysis on questionnaire data from 2005 and 2008. Both recommended and non-recommended methods are found to be commonly used, with large companies...

Despite that interaction terms are standard tools of regression analysis, the side effects of the inclusion of these terms in models estimated by ordinary least squares (OLS) are yet not fully penetrated. The inclusion of interaction effects induces multicollinearity problems since all non-zero...

In ridge regression the estimation of the ridge parameter is an important issue. This paper generalizes some methods for estimating the ridge parameter for probit ridge regression (PRR) model based on the work of Kibria et al. (2011). The performance of these new estimators are judged by...

This paper analyses the effect on meal consumption away from home of a point-of-purchase healthy symbol. We base the analysis on a field experiment in a lunch restaurant. Our results suggest that meal consumption does not increase if the meal is labeled with a healthy symbol. Also, the mean...

The increase and expansion of out-of-town shopping centres is often criticized for out-competing retail business within city centres. City retailers’ own perceptions of competition within and between retail districts are here analyzed via choice experiments in the city of Gävle, Sweden....

Previous research shows that taste is one of the most important factors in determining food choices, and that food choices may be affected by ”nudging”. We analyze how taste, as determined by meal attributes, and nudging affects consumption of a healthy labeled meal. Our analysis is based on...

In this the size and power properties of the common factor Im, Pesaran and Shin (CIPS), Wald (W), likelihood ratio (LR) and Lagrange multiplier (LM) tests are investigated when the error term follows a spatial error model. The results from the Monte Carlo simulations used in this study, firstly...

Most firms do not grow, and a small number of high-growth firms seem to create most new jobs. These firms have therefore received increasing attention among policymakers. The question is whether high-growth tends to persist? We investigate this question using data on 432,689 observations in...

The market share for parallel imports when pharmacies can negotiate discounts with parallel traders and sellers of locally sourced products is analyzed both theoretically and empirically. The theoretical model shows that, with discount negotiations, pharmacies will sell locally sourced products...
