The debate regarding rising temperatures and CO2 emissions has attracted the attention of economists employing recent econometric techniques. This article extends the previous literature using a dataset that covers 800?000 years, as well as a shorter dataset, and examines the interaction between temperature and CO2 emissions. Unit root tests reveal a difference between the two datasets. For the long dataset, all tests support the view that both temperature and CO2 are stationary around a constant. For the short dataset, temperature exhibits trend-stationary behaviour, while CO2 contains a unit root. This result is robust to nonlinear trends or trend breaks. Modelling the long dataset reveals that while contemporaneous CO2 appears positive and significant in the temperature equation, including lags results in a joint effect that is near zero. This result is confirmed using a different lag structure and Vector Autoregressive (VAR) model. A Generalized Method of Moments (GMM) approach to account for endogeneity suggests an insignificant relationship. In sum, the key result from our analysis is that CO2 has, at best, a weak relationship with temperature, while there is no evidence of trending when using a sufficiently long dataset. Thus, as a secondary result we highlight the danger of using a small sample in this context. 相似文献

This paper explores the ability of some popular income distributions to model observed skewness and kurtosis. We present the generalized beta type 1 (GB1) and type 2 (GB2) distributions' skewness–kurtosis spaces and clarify and expand on previously known results on other distributions' skewness–kurtosis spaces. Data from the Luxembourg Income Study are used to estimate sample moments and explore the ability of the generalized gamma, Dagum, Singh–Maddala, beta of the first kind, beta of the second kind, GB1, and GB2 distributions to accommodate the skewness and kurtosis values. The GB2 has the flexibility to accurately describe the observed skewness and kurtosis. 相似文献

ABSTRACTThis research advances understanding of mobile device use in a leisure context by applying and expanding the Unified Theory of the Acceptance and Use of Technology 2 (UTAUT2) to festival settings. Through on-site surveys at three festivals the UTAUT2 model and an adapted version for mobile device use at a festival were examined using confirmatory factor analysis and structural equation modelling. Results reveal that the modified UTAUT2 demonstrates good fit, and the main factors affecting device use at festivals are performance expectancy, hedonic motivation, habit and age. The findings suggest that the festival context plays an important role in understanding use and should be included in future research. By knowing factors that affect use, practitioners can design experiences where technology enhances the festival and does not interfere with attendees’ experiences. 相似文献

Abstract. The paper investigates how monetary policy shocks influence the composition of firms' external finance given that firms are heterogeneous. Heterogeneity stems from differences in the availability of internal funds and in the monitoring costs associated with bank finance. These costs are determined by the intensity of the lending relationship. By using a delegated monitoring approach it is found that bank loans serve as a substitute for internal funds if the lending relationship is sufficiently close. Moreover, banks with strong credit ties to their customers are not only able to protect borrowers from liquidity constraints following a monetary tightening but are even able to extend their business lending. 相似文献

This paper tests the efficiency of the football betting market and develops a model of the determinants of the closing spread. The empirical results suggest that the football betting market is not perfectly efficient. The evidence also suggests that, contrary to previous studies, gamblers that do bet the long shots are acting as rational individuals attempting to maximize their return for a given level of risk. Finally, at least six variables were found to be statistically significant factors in determining closing spreads in the football betting market. 相似文献

An empirical investigation was conducted to evaluate the impact of guilt arousing marketing communications. The results indicated that guilt as a distinct emotion can be aroused to the extent of changing message specific attitudes. However, it was not possible to change either global attitudes or behavioral intentions. One reason for the failure of guilt arousing marketing communications to affect global attitudes and behavioral intentions may be due to counterarguing on the part of message recipients. 相似文献
