We examine inflation and uncertainty in the UK with a version of the Markov Switching model, which allows for changes in the variance as well as in the mean and persistence of a series. We find that the UK’s attempts at exchange rate pegs in the form of shadowing the deutschmark and entering the ERM were ineffective, and in the latter case counterproductive in lowering inflation uncertainty. The 1981 budget, however, greatly lowered uncertainty, and the adoption of a formal inflation target also had a palpable, negative impact on inflation uncertainty. As a suggestive exercise, we examine inflation uncertainty in the US, and find that, over 2005–2008, in the absence of an inflation target, uncertainty rose in the US, while uncertainty remained low in the UK over this period of rising commodity prices and financial turmoil. 相似文献

This paper studies the implications for business cycle dynamics of heterogeneous expectations in a stochastic growth model. The assumption of homogeneous, rational expectations is replaced with a heterogeneous expectations model where a fraction of agents hold rational expectations and the remaining fraction adopt parsimonious forecasting models that are, in equilibrium, optimal within a restricted class. Our approach nests the literature on rational expectations in business cycle models with a recent approach based on adaptive learning. We demonstrate that (i.) heterogeneous expectations can lead to substantial improvement in the internal propagation of equilibrium business cycle models and (ii.) the internal propagation depends on the degree of heterogeneity. A calibrated model with heterogeneity provides a closer fit to business cycle data than its representative agent, rational expectations counterpart. 相似文献

This paper investigates adolescent online shopping and self-efficacy development in the virtual setting. The authors present and test a model of antecedents and mediators to two dimensions of online consumer self-efficacy. Additionally, a discriminant analysis finds that more involved adolescent online shoppers can be differentiated from less involved online shoppers on key variables of interest-shopping motivations, self-efficacies, shopping behaviors, and relative influence in household decision-making. 相似文献

By any measure economists have played increasingly prominent roles in antitrust policy making, at least since the early 1970s. Indeed, the approach to the analysis of public policy toward business pioneered by Chicago school economists dominates the academic literature nowadays. According to the Chicago school's adherents, their insistence that antitrust be examined through the lens of price theory should have produced discernably ‘better’ (read pro-consumer) laws and ‘better’ law enforcement. This paper contends that economists have in fact not had a positive influence on antitrust policy, but have instead actively contributed to its use as a way of subverting competitive market forces. 相似文献

Plant-based precision nitrogen fertilizer application technologies have been developed as a way to predict and precisely meet nitrogen needs. Equipment necessary for precision application of nitrogen, based on sensing of growing wheat plants in late winter, is available commercially, but adoption has been slow. This article determines the expected profit from using a plant-sensing system to determine winter wheat nitrogen requirements. We find that plant-sensing systems have the potential to be more profitable than traditional nonprecise systems, but the existing system simulated was roughly breakeven with a traditional system. 相似文献
