In an important and influential paper, Card and Krueger argued that proxies for school quality positively affect the rate of return to future education. In this paper, we analyze a variant of the Card and Krueger model using a hierarchical Bayesian approach and school-level quality data from the...

This study examines the effect of R&D tax credits on innovation activities of Canadian manufacturing firms. Over the 1997-1999 period the Federal and Provincial R&D tax credit programs were used by more than one third of all manufacturing firms and by close to two thirds of firms in...

This paper examines the value to Swedish citizens of reducing the risk for salmonella bacteria in chicken filet. The contingent valuation (CV) study is based on the results of a postal questionnaire that was distributed to 2 000 randomly selected Swedish citizens aged 18-74. The valuation format...

A product is called technically inefficient when it has higher price and/or lower quality than others. Technical inefficiency of product has been conceptualized since Lancaster (1966), and empirically measured by many researchers, for example, Fernandez-Castro and Smith (2002) and Lee et al....

This paper considers the power and size properties of some well known nonparametric linear rank tests for location and scale as well as the Kolmogorov-Smirnov omnibus test and proposed alternatives to it. Independence between some classes of linear rank tests is established facilitating their...

The basic idea in this paper is that labor supply can be viewed as a function of the entire budget set, so that one way to account non-parametrically for a nonlinear budget set is to estimate a nonparametric regression where the variable in the regression is the budget set. In the special case...

This paper evaluates the tax reforms carried out in Sweden between 1980 and 1991. We use a recently developed nonparametric labor supply function to account for the behavorial responses of the taxed individuals. We decompose the tax reform to study how the separate components influence hours of...

Rating scales for outcome variables produce categorical data which are often ordered and measurements from rating scales are not standardized. The purpose of this study is to apply commonly used and novel methods for paired ordered categorical data to two data sets with different properties and...

Subjective assessments of pain, quality of life, ability etc. measured by rating scales and questionnaires are common in clinical research. The resulting responses are categorical with an ordered structure and the statistical methods must take account of this type of data structure. In this...

The efficiency of universities is attracting increased interest, with most studies comparing the performance between different universities. However, the within-university variation is largely overlooked in the literature. Using data envelopment analysis this paper identifies heterogeneity in...
