We use large linked employer-employee data to analyze wage inequality patterns in Central and Eastern European (CEE) countries between 2002 and 2014. We show that, unlike in many other advanced economies, wage inequality levels have decreased in almost all CEE countries. These reductions in wage inequality resulted from disproportionately large increases in wages at the bottom of the wage distribution, and from decreases in between-firm wage inequality. We further find that the declines in wage inequality were driven by large wage structure effects that compensated for changes in the composition of workers. 相似文献

We point out that fiscal multipliers derived from SVAR-models include the predicted future path of policy instruments. After the initial shock, net taxes and government expenditures react to each other and are autocorrelated. In a counterfactual simulation, we report fiscal multipliers that abstract from these dynamic responses. 相似文献

Wildlife tourism experiences have the potential to positively impact tourists’ awareness, appreciation and actions in relation to the specific wildlife they encounter and the environment in general. This paper investigates the extent of such impact across multiple sites, and uses Structural Equation Modelling to identify factors that best predict positive long-term learning and environmental behaviour change outcomes. Three sets of variables were measured – visitors’ entering attributes (including pre-visit environmental orientation and motivation for the visit), salient aspects of the experience, and short- and long-term learning and environmental behaviour change outcomes. Although attributes such as pre-visit commitment and motivation to learn were among the best predictors of the long-term impact of the experience, there was evidence that aspects of the experience were also important. In particular, reflective engagement which involved cognitive and affective processing of the experience was found to be associated with short- and long-term environmental learning outcomes. The implications for wildlife tourism managers are discussed. 相似文献

Even in protected areas, it is inevitable that any human use will produce some impact on natural resources. This study identifies visitors’ tolerance of potential negative ecological impacts from tourism activities and facilities in a Norwegian national park context, based on park visitors’ expressed degree of acceptance of negative effects on particular species of wildlife (wild reindeer and raptors) and on vegetation. Attitudes were analysed using psychographic scales, reflecting respondents’ nature orientations, their specific facility desires, their preferences in a wilderness setting and their concerns about human interaction with the natural environment. Fourteen research hypotheses were tested. Findings demonstrated that the psychographic scales explained more variation in attitudes than most social background and trip characteristics. Higher levels of education among visitors were strongly associated with increased ecological concern; age and gender were not. There was generally strong ecological awareness and eco-centrism among park visitors in general, with a small proportion of wilderness purists. Better trail conditions, signposting and interpretation were sought. But park visitors were also found to possess a complex mixture of needs and drivers. The study found significant potential for strategic alliances between tourism and conservation interests, and key value issues for park governance systems. 相似文献

In this paper the incentives for platform sponsors to open up their networks for independent rivals is analyzed. It is shown that open access may increase the platform sponsors’ profit levels and enhance quality improving investments. In addition, it is shown that a commitment to allow entry reduces the difference between ex ante and ex post compatibility incentives. 相似文献
