Temporal aggregation in general introduces a moving‐average (MA) component in the aggregated model. A similar feature emerges when not all but only a few variables are aggregated, which generates a mixed‐frequency (MF) model. The MA component is generally neglected, likely to preserve the possibility of ordinary least squares estimation, but the consequences have never been properly studied in the MF context. In this paper we show, analytically, in Monte Carlo simulations and in a forecasting application on US macroeconomic variables, the relevance of considering the MA component in MF mixed‐data sampling (MIDAS) and unrestricted MIDAS models (MIDAS–autoregressive moving average (ARMA) and UMIDAS‐ARMA). Specifically, the simulation results indicate that the short‐term forecasting performance of MIDAS‐ARMA and UMIDAS‐ARMA are better than that of, respectively, MIDAS and UMIDAS. The empirical applications on nowcasting US gross domestic product (GDP) growth, investment growth, and GDP deflator inflation confirm this ranking. Moreover, in both simulation and empirical results, MIDAS‐ARMA is better than UMIDAS‐ARMA.  相似文献

Energy efficiency is an effective strategy to reduce household energy consumption. Investments in energy efficiency measures (EEMs) result in reduced energy bills and increased comfort for households, while also contributing to national environmental targets. This article examines an energy efficiency scheme in Ireland and investigates the factors that determine investments in energy efficiency measures and the motivations of Irish households to participate in energy saving programs and adopt EEMs. The paper investigates three key research questions: the determination of investments in EEMs, with special focus on motivations and their relative importance; the consistency of motivations over the course of the decision-making process; and the consistency of determinants and motivations for investments in EEMs across different measures. The paper studies the implementation of seven energy efficiency measures in residential houses throughout Ireland. Results indicate that the decision to ultimately apply and invest in EEMs is mainly driven by monetary or economic factors such as gains in energy savings and the private cost of the measures. Comfort gains are found to be a secondary factor and environmental benefits of EEMs are found to be of little concern when making investment decisions. Finally, we suggest focusing on providing information about the benefits of the EEMs on energy savings and improvements in comfort in order to increase the adoption of EEMs by households in Ireland.  相似文献

Knowledge about the existence and source of national differences in willingness to take risks plays a vital role in ensuring successful communication, collaboration, and understanding across countries, from the personal to the organizational and political/social domain. The current study investigates differences in financial risk-taking willingness between countries as a function of social and state ‘cushioning’, i.e. the extent of a person’s social support network and the state’s social-safety support network. The study compares large-scale household data and self-reports on willingness to take financial risks across three countries differing in their state support networks: Austria, Italy and the United States. Results show that personal social support network size influences risk-taking willingness (social cushioning). Furthermore, and most notably, we find evidence of an interactive relationship between social and state cushioning. High state cushioning renders the influence of social cushioning on financial risk-taking willingness less important. Contributions to management and business practice as well as theory on the influence of personal distance to financial support on risk-taking willingness are discussed.  相似文献

We study a finite-dimensional approach to the Heath–Jarrow–Morton model for interest rate and introduce a notion of approximate consistency for a family of functions in a deterministic and stochastic framework. This amounts to asking the decrease of the minimum distance in least squares sense. We start from a general linearly parameterized set of functions and extend the theory to a nonlinear Nelson–Siegel family. Necessary and sufficient condition to have approximately consistency are given as well as a criterion of stability for the approximation.  相似文献

This article presents a strategic model of liability and litigationunder court errors. Our framework allows for endogenous choiceof level of care and endogenous likelihood of filing and disputes.We derive sufficient conditions for a unique universally divinemixed-strategy perfect Bayesian equilibrium under low courterrors. In this equilibrium, some defendants choose to be grosslynegligent; some cases are filed; and some lawsuits are dropped,some are resolved out of court, and some go to trial. We findthat court errors in the size of the award, as well as damagecaps and split awards, reduce the likelihood of trial but increasefiling and reduce the deterrence effect of punitive damages.We derive conditions under which the adoption of the Englishrule for allocating legal costs reduces filing.  相似文献

This paper interrogates the polarized and heated discussions about mountain bike tourism in Austrian forests, with several organizations favoring permitting biking on all forest roads, using claimed tourism development opportunities, while other stakeholders including hikers, hunters and landowners wish to restrict development. An international literature review on the value and impacts of mountain biking shows that both sides have oversimplified complex cases. The paper draws on 12 in-depth interviews with Austrian tourism destination and mountain bike experts to find ways forward. Results suggest that in Austria, bike tourism will increase in the future, supported by new bike technology, including electric bikes and new hand-held route information technology. It notes the complexity of the market for mountain and other forms of cycle tourism, and the pressing need to create not more trails but more sophisticated tourism products, including appealing and well-maintained trails plus attractive leisure infrastructure (bike rental, service and repair facilities, attractive localities, accommodation suited to the mountain bikers’ needs, etc.). Collaborative planning with all stakeholders, better trail construction standards adapted to differing preferences, needs and environmental conditions as well as clear standards for monitoring are prerequisites of an Austrian strategy for sustainable cycle tourism development and management, which can be replicated elsewhere.  相似文献

We present a novel series of Chilean top-income shares covering half a century, mainly based on income-tax declarations and the National Accounts. Such a time frame of analysis is still rare in the literature of developing countries. We distinguish between a fiscal-income series (1964–2017) and an adjusted series (1990–2017). The former covers individual income, while the latter also includes corporate undistributed profits, which affects both levels and trends. The fiscal-income estimates start with low levels and a decreasing trend over the 1960s. They then increase rapidly during the dictatorship years (1973–89). The series ends with a high, yet slowly decreasing, concentration for most of the recent democratic period (1990–2017). By contrast, the adjusted series has followed a U-shape since the return of democracy, contradicting the established consensus on falling inequality over the period. Furthermore, Chile ranks among the most unequal countries in both the OECD and Latin American countries over the period.  相似文献
