a r t i c l e i n f o A recent paper (Ecological Economics 69, 2010, pp. 1604–1609) has addressed the issues of dimensional homo-geneity of equations and non-linear transformations of variables in economic and ecological economic models. The authors argued that logarithmic transformation cannot be used when variables are dimensional, presented several examples of purportedly incorrect use in ap...

in macroeconomic studies, social welfare is assumed as a function of inflation and unemployment. although the social welfare function which is dependent to unemployment and inflation variables has been used widely in macroeconomic theories, but this relation needs to be tested through empirical observations. this paper, using variables such as to economics of happiness area and subjective wellb...

This paper studies a class of multidimensional screening models where different type dimensions can be aggregated into a single-dimensional sufficient statistic. The paper applies results of totally positive functions to show that some critical properties of distributions of asymmetric information parameters, such as increasing hazard rate, monotone likelihood ratio, and singlepeakedness are pr...

Many economic data sets are contaminated by the mismeasured variables. The problem of measurement errors is one of the most fundamental problems in empirical economics. The presence of measurement errors causes biased and inconsistent parameter estimates and leads to erroneous conclusions to various degrees in economic analysis. Techniques for addressing measurement error problems can be classi...
