Impure public goods and technological interdependencies

摘要

Purpose - This paper aims to investigate empirically the findings of an analytical impure publicrngood model. The impure public good model described in this study allows for the application ofrndifferent technologies generating public and private characteristics. The influence of the individualrntechnologies on the total level of (impure) public good provision is of main concern in this study.rnDesign/methodology/approach - After the illustration of the impure public good model, thernanalytical results are compared to the results of a numerical approach based on climate policy inrnGermany.rnFindings - The study shows that comparative static analyses do not always generate clear results.rnTherefore, the numerical approach is helpful to derive unambiguous results. The paper finds thatrntechnologies which exclusively generate private characteristics may have significant effects on totalrnimpure public good provision, since they may replace the private characteristics of the impure publicrngood.rnOriginality/value - This paper provides useful information on the influence of the individualrntechnologies on the total level of (impure) public good provision.
