We estimate the effect of employment density on wages in Sweden in a large geocoded data set on individuals and workplaces. Employment density is measured in four circular zones around each individual's place of living. The data contains a rich set of control variables that we use in an...

Multilevel (ML) models allow for total variation in the outcome to be decomposed as level one and level two or ‘individual and group’ variance components. Multilevel Mixture (MLM) models can be used to explore unobserved heterogeneity that represents different qualitative relationships in...

Consumers pay a premium for Fair Trade coffee, often assuming that it mainly benefits poor coffee farmers. However, several studies report that most of the premium accrues to actors in the consumer countries, such as roasters and retailers. This paper analyses how the returns to Fair Trade are...

Many countries have undertaken central-bank independence reforms, but the years of implementation differ. What explains such differences in timing? This is of interest more broadly, as it sheds light on factors that matter for the speed at which economic reforms come about. We study a rich set...

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....

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...
