Croatia's total exports, therefore goods exports too, can be increased by more effective economic diplomacy. However, it is worthwhile to problematize whether Croatian economic diplomacy performs the activities that Croatian exporters expect from it. Furthermore, it is questionable whether the results of the work of Croatian economic diplomacy cover the costs of its operation. Therefore, this doctoral thesis problematizes the effectiveness of Croatian economic diplomacy, that is, its results. The research objectives of the thesis are three models for performance measurability of Croatian economic diplomacy from the perspective of exporters. Elements of the research objectives are descriptions of the attitudes of Croatian exporters to the importance of activities selected by Croatian economic diplomats. The focus of the auxiliary research is economics of experience. Elements of the auxiliary research objective are cybernetic models of economic value creation in the experience economy and in traditional economies, the key differences between them and economic diplomacy in the experience economy. The aim of the research is to describe three models for performance measurability of Croatian economic diplomacy from the perspective of all respondents, the respondents from the manufacturing industry and those who generate more than 30% of their total revenues through exports. Descriptions of the models contain 5 most important activities of Croatian economic diplomacy according to the respondents, out of 21 that were offered for evaluation. The first auxiliary research objective is to describe the experience economy. The description contains the definition of the term, cybernetic models of economic value creation both in the experience economy and traditional types of economies, and an analysis of the differences between these models. The second auxiliary research objective is to describe economic diplomacy in the experience economy. The description contains the definition and qualitative analysis of the term.
