The present article aims to analyse wage-labour productivity causalities in Croatia and Slovenia using cointegration methods based on monthly time series data of variables for labour productivity and real gross wages in tourism industry during the period December 1999-January 2020. The data vector is integrated by chain indices with the constant base January 2000 ¼ 100. A stochastic trend and shocks are covered in the analysis. Shocks are linked to the European Union accession, and economic crisis following with overwhelmed tourist arrivals. The contribution of the research is two-fold. First, the equations for at most normal distributed variables of labour productivity and real wages in tourism are exposed. Three spatial cointegration relations confirm labour productivity integrity of the regional tourism market. Second, pair-wise causalities indicate one cointegrated vector for labour productivity, which drives real gross wages in tourism sub-industries. These results suggest that for a higher non-seasonal assessment of real gross wage, the labour productivity should rise, i.e. less workers, more robotization or more tourist arrivals with better quality solutions. These findings are at most important to be implemented after the COVID-19 infection crisis with expected restructurings and digital transformation in the tourism industry.

This study considers diversification effects and significant influences on tourist arrivals as a vital export direction. Different quantitative methods, namely a cointegrated-autoregressive model, panels, sentiment and sensitivity analysis, were used in this study. The time-series data for Croatia and Slovenia were isolated from several secondary sources. The variables examined in this approach are tourist arrivals, precipitations, sunny days, earthquakes, microbes and CO2 emissions. The study results showed that there is a severe negative effect on tourist arrivals defined by viruses. Moreover, there is a significant decisive effect of weather conditions on tourist arrivals. Nevertheless, it is necessary to move past Covid-19 pandemic discussions to yield more accurate tourism supply forecasts, while demand is already somehow low since the beginning of 2020. The primary significance is to develop a broader thinking about the impacts of CO2 emissions on the tourism escorted to official tourist websites.

This paper investigates causal relationships between gross domestic product (GDP) and the number of small and medium sized enterprises (SMEs) controlled for unemployment rates (UNR) within Slovenia and Croatia. Macro-economic time series data on GDP, SMEs and UNR are analysed in a unit root framework and applied regression analysis. These processes are known as the Johansen co-integration test and Granger-Causality-test. The results show that UNR, GDP and SMEs did not have causal relationships in Croatia between January 2008 and December 2013. UNR and SMEs have a bidirectional relationship in Slovenia with a greater number of SMEs per capita than in Croatia. During their economic recovery period between January 2014 and December 2017, Slovenia and Croatia have experienced the causal unidirectional relation from SMEs to GDP as a positive signal under seen to policy makers on usefulness of investment in SMEs during economic prosperity. The results of a vector autoregressive model suggest a 1% change in the number of SMEs in Croatia decreases GDP in the time of crisis by almost 1.8%. For Slovenia, there is no statistically significant cointegration vector pertained to SMEs-led growth. Finally, the unidirectional causality relation from SMEs to UNR is statistically significant for Slovenia.

Public-private partnership (PPP) is a method for developing sustainable development that has been proven worldwide and endorsed in practice, and its ultimate aim is to increase the overall well-being of society. In a variety of ways, it brings together the interests of the public, private and civil sector in meeting specific needs for augmenting the quality and/or availability of services and products The European Union (UN) has not always supported the co-financing of projects devised as PPP. Recently, however, it has begun to encourage a wider application of this form of financing that demonstrates a huge potential in accomplishing public services, that is, projects intended for the public. Marketing and promotion, product development, education, financing and investment, and environmental protection are but some of the areas of public-private collaboration in tourism in a global setting. The purpose of this paper is to provide an outline of world experience and practice in PPP with emphasis on the EU, so that Croatia, by taking under consideration these experiences, advantages and disadvantages, may define an appropriate legal and business framework and identify the criteria for the successful implementation of PPP in its economy, and in particular, in tourism, one of its highest-growth industries.
