We take as a starting point the existence of a joint distribution implied by different dynamic stochastic general equilibrium (DSGE) models, all of which are potentially misspecified. Our objective is to compare “true” joint distributions with ones generated by given DSGEs. This is accomplished via comparison of the empirical joint distributions (or confidence intervals) of historical and simulated time series. The tool draws on recent advances in the theory of the bootstrap, Kolmogorov type testing, and other work on the evaluation of DSGEs, aimed at comparing the second order properties of historical and simulated time series. We begin by fixing a given model as the “benchmark” model, against which all “alternative” models are to be compared. We then test whether at least one of the alternative models provides a more “accurate” approximation to the true cumulative distribution than does the benchmark model, where accuracy is measured in terms of distributional square error. Bootstrap critical values are discussed, and an illustrative example is given, in which it is shown that alternative versions of a standard DSGE model in which calibrated parameters are allowed to vary slightly perform equally well. On the other hand, there are stark differences between models when the shocks driving the models are assigned non-plausible variances and/or distributional assumptions.  相似文献

This paper investigates the determinants of a “successful” IPO from a corporate governance perspective upon a representative sample of European listings from 2000 to 2015. We use an extensive dataset of market performance, financial data, and corporate governance characteristics to run the investigation. Differently from previous studies, our analysis embraces both a short‐term perspective and a medium–long‐term perspective, where the board of directors seems to perform different tasks, moving from a value creation to a value protection strategy. Among the others, we find that board size, board independence, and their qualifications, together with their experience in other boards, are associated with a positive performance of the IPO in a short‐term horizon and in the medium–long‐term period, although significant differences emerge among those time perspectives.  相似文献

This paper analyses the economic impact of digital technologies in Europe distinguishing between different stages/domains of the digitalization process. A set of composite Information and Communication Technologies (ICT) indicators is used for capturing the access to ICTs, the ability to use them and the digital empowerment of individuals in key social and economic domains. We argue that the mere accessibility to ICT facilities is only a pre-condition for moving towards a digitalized society, while the ‘level’ and the ‘quality’ in the use of these technologies, as well as the conditions facilitating or hampering digital empowerment, play a much more important role. Several transmission mechanisms from ICT access, usage and digital empowerment to key macro-economic variables (namely labour productivity, gross domestic product per capita, employment growth and the employment rate) are identified. The econometric evidence supports our hypotheses showing that the usage of ICT, and mostly digital empowerment, exert the major economic effects, especially on employment also favouring the inclusion of ‘disadvantaged’ groups in the labour market. We conclude that digitalization may drive productivity and employment growth and that inclusive policies may effectively contribute to bridge the gap between the most favoured and the disadvantaged parts of the population, thus helping in achieving the 2020 Europe targets.  相似文献

Research on financial constraints of very small firms is scarce because it is difficult to observe and measure their transactions. Previous studies on small enterprises in post-communist countries have focused either on the effect of financing constraints on business growth (Budina et al., 2000, Economics of Transition 8(2), 453–475; Bratkowski et al., 2000, Economics of Transition 8(1), 101–116) or on the effect of property rights (Johnson et al., 2002, American Economic Review 92(5), 1335–1357). This paper provides evidence on both. It turns out that financing constraints and property rights considerations affects investment in firms of different age differently. Younger firms face higher information costs and their expansion is more dependent on the availability of internal funds than is the expansion of older firms. This paper also finds that while the financial sector did not channel funds to the most successful businesses, there is evidence that loans were given to firms that had more transparent transactions. Results also indicate that the security of property rights does not influence investment in young firms, which is interpreted to mean that only the most efficient entrepreneurs entered the market. In older small firms, investment is negatively influenced by the index of security of property rights suggesting that these firms might have “secured” their property rights by bribes. Improvements in the security of property rights, therefore, would help more micro enterprises to be born as well as decrease transaction cost of established enterprises.   相似文献

This study focuses on the role of public authorities in the governance of tourism for sustainable development at national level. Departing from an overview of international recommendations, it analyses whether those recommendations are reflected in the way public authorities influence domestic tourism in the Netherlands. The conclusion is drawn that, currently, the internationally recommended horizontal and vertical coordination of public authorities and their policies is missing. This is largely due to a design approach that follows from neo-liberal principles of governance, as opposed to the sustainability performance of the tourism sector. The paper then discusses the results of a survey carried out to map the extent to which Dutch tourism stakeholders would be in favor of adopting measures to improve coordination. It is concluded that, although there is support for more coordination, there is no converging vision on how specific aspects of it should be best organized. The paper highlights the need for multi-stakeholder debates that should consider the links between governance features and the sustainability performance of tourism.  相似文献

Demand for Protected Area (PA) tourism continues to grow, raising concerns for its environmental sustainability. Numerous sustainable tourism guidelines and best practice examples exist for separate aspects of PA regulation and management. However, such efforts are insufficient to reliably and holistically understand how regulation can mediate the relationship between tourism development and PA environmental sustainability. This paper proposes a theory development project, to map the compatibility and interplays among various regulatory approaches, and their consequences for sustainable PA tourism. The project is initiated here by taking the first steps toward a concession-related theory of regulation. The focus on concessions has been chosen because concessions are the most under-researched aspects of PA tourism regulation. Four regulatory aspects are selected and conceptualized in this paper: the approaches to PA planning, the types of monitoring undertaken, the methods of concession allocation and the design of environmental requirements in concession contracts. Methodologically, grounded theory is used, with data collection relying on written sources. The paper develops two sets of narrative statements regarding the prospects for PA environmental sustainability, under particular examples of concession-related regulation. The conclusion articulates several research questions, as an immediate research agenda, and calls for an international research group to be formed.  相似文献

In recent years many cross-national comparative surveys, such as Gender and Generation Programme, International Social Survey Programme, European Quality of Life Survey, or General Social Survey, have included assessment of social support networks. Generally, two approaches were used; the name generator approach and the role relation approach. As more cross-country surveys are conducted every year, it may seem reasonable to use such data sets, since they provide high quality comparisons across countries. However, one should pay close attention to the measurement instruments, as these may cause unintentional but systematic variability in the observed data. While the data from each survey can be of high quality ??per se??, we claim that results from these surveys are not comparable, owing to their different measurement approaches and survey instruments. In this paper we present data from several experiments which show that scientific findings from these surveys depend significantly on questionnaire design.  相似文献
