We propose a way of testing a subset of equations of a DSGE model. The test draws on statistical inference for limited information models and the use of indirect inference to test DSGE models. Using the numerical small sample distribution of our test for two subsets of equations of the Smets–Wouters model we show that the test has accurate size and good power in small samples, and better power than using asymptotic distribution theory. In a test of the Smets–Wouters model on US Great Moderation data, we reject the specification of the wage‐price but not the expenditure sector. This points to the wage‐price sector as the source of overall model rejection. 相似文献

We review the methods used in many papers to evaluate DSGE models by comparing their simulated moments with data moments. We compare these with the method of Indirect Inference to which they are closely related. We illustrate the comparison with contrasting assessments of a two-country model in two recent papers. We conclude that Indirect Inference is the proper end point of the puzzles methodology. 相似文献

This paper proposes a simple benchmark for monetary policy. Assuming the true model of the economy is unknown, it is based on an unrestricted vector autoregression (VAR). The key result is that instead of deriving optimal policy using the original VAR equations as the constraint, when no restriction is placed on the correlation structure of the VAR disturbances, the constraint should be formed from a transformation of the VAR. This method is applied to the USA, 1964–2009. Significant welfare gains are found compared with actual policy and using a Taylor rule. Incorporating a zero interest rate lower bound lowers output and inflation. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

We analyze the impact of leniency programs on the behavior of firms participating in illegal cartel agreements in a two-stage
repeated game model. Our approach takes into account asymmetric punishment effect and allows to discuss the design of leniency
programs in the setting with asymmetries. The main contribution of the paper is that we consider heterogeneous firms. This
heterogeneity results in additional costs in case of disclosure of the cartel, which are caused by asymmetric punishments.
Next, following current antitrust rules, we analyze effects of the strictness of leniency programs, which reflects the likelihood
of getting a complete exemption from fine even in case many firms self-report simultaneously. Our main conclusion is that
leniency programs work better for small companies, since a lower rate of law enforcement is needed in order to induce self-reporting
by smaller firms, while big firms are less likely to start a cartel in the first place given the possibility of self-reporting
in future. Finally, we analyze optimal enforcement strategies of the antitrust authority and conclude that the authority with
limited resources should implement more generous leniency rules the more cartelized the economy is. 相似文献

This study explores the effect of environmental, social, and governance (ESG) performance on market value and performance in the context of mergers and acquisitions. We examine whether acquisition of targets with better ESG performance can help acquirers to increase their own ESG performance and whether the market values the increased ESG performance positively. Moreover, we explore whether the acquisition of targets with better ESG performance affects the market value of acquirers. For this study, we utilize a sample of 100 European mergers and acquisitions between 2003 and 2017, for which matching data on the ESG performance of both the target and acquiring firms are available. Our results show that the postmerger ESG performance of the acquirer increases following the acquisition of a target that has higher ESG performance than that of the acquirer in the premerger stage, whereas the postmerger market value of the acquirer increases following an increase in the acquirer's postmerger ESG performance in relation to its premerger ESG performance. Finally, we provide partial evidence of a positive relationship between the postmerger market value of the acquirer and the acquisition of a target with higher ESG performance than itself in the premerger stage. 相似文献

This article has the aim of presenting the basis for a new, clearer classification of restaurant attributes. The research followed an interpretive approach with a systematic review of the literature, compared and contrasted with the findings of six focus group interviews. A new model was devised with seven categories of restaurant attributes. This article presents a model that needs to be tested. Also, follow-up articles with more detail about the attributes under each category will be presented. This article organizes the disparate literature on restaurant attributes and looks into the relationship between attributes, particularly its influence on perceived consumer value. 相似文献

We use the method of indirect inference, using the bootstrap, to test the Smets and Wouters model of the EU against a VAR
auxiliary equation describing their data. We find that their model generates excessive variance compared with the data. But
their model fits the dynamic facts quite well if the errors have the properties assumed by SW but scaled down. We compare
a New Classical version of the model which also performs reasonably if error properties are chosen using New Classical priors
(notably excluding shocks to preferences). Both versions have (different) difficulties fitting the data if the actual error
properties are used. A model combining rigid and flexible-wage/price sectors, with a weight of around 5% on the rigid sector,
does best in fitting the data. 相似文献

Peter Wickens, who is Director of Personnel and Information Systems of the Nissan Motor Manufacturing (UK) Ltd, puts ‘lean production’ in its historical context, examines some of the criticisms of the system and considers some of the changes taking place in Japan. He goes on to suggest possible ways forward and makes the case for a system of ‘lean production’ managed by people who care about people. 相似文献
