The predictive likelihood is useful for ranking models in forecast comparison exercises using Bayesian inference. We discuss how it can be estimated, by means of marzginalization, for any subset of the observables in linear Gaussian state‐space models. We compare macroeconomic density forecasts for the euro area of a DSGE model to those of a DSGE‐VAR, a BVAR and a multivariate random walk over 1999:Q1–2011:Q4. While the BVAR generally provides superior forecasts, its performance deteriorates substantially with the onset of the Great Recession. This is particularly notable for longer‐horizon real GDP forecasts, where the DSGE and DSGE‐VAR models perform better. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

Abstract

The present paper proposes and investigates a procedure for numerical evaluation of the transition probabilities for a time-inhomogeneous Markov process when the intensities are known (estimated). The procedure is based on Taylor-expansion of the transition probabilities linked with the Chapman-Kolmogorov equations.  相似文献

This article examines deliberative, emotional, and sociocultural processes in consumption. The authors draw upon basic processes from two leading theories in social psychology, the theory of planned behavior (TPB) and the model of goal‐directed behavior (MGB), to develop a comprehensive approach to decision making more appropriate for many consumption decisions, and revise the representation and modeling of key variables to better reflect how social psychological processes relate to consumer behavior. A survey was conducted among real adult consumers of bacalhau in Portugal. Because it is most common for women to prepare bacalhau meals in Portugal, 153 female participants were recruited for this survey. The results show that the TPB, and especially the MGB, are found to explain food consumption decisions well but only after the approaches are modified in form and content to accommodate the complex emotional and social aspects of the consumption context. The results also show that the effects of key determinants of desire in the MGB are contingent on the traits of food involvement and cultural orientation (i.e., degree of vertical individualism). The approach taken herein overcomes limitations of existing theories by synthesizing relevant processes across two leading theories and by introducing new variables and processes, thereby showing that the organization of these processes and their contingency on cultural variables regulate consumption.  相似文献

The fact that education provides both a productive and a consumptive (nonproductive) return has important and, in some cases, dramatic implications for optimal taxes and tuition fees. Using a simple model, we show that when the consumption share in education is endogenous and tuition fees are unconstrained, the optimal tax/fee system involves regressive income taxes and high tuition fees. A progressive labor income tax system may, on the other hand, be a second‐best response to politically constrained, low tuition fees. Finally, the existence of individuals with different abilities will also move the optimal income tax system toward progressivity.  相似文献

In this article we discuss the concept of risk in an ontological perspective. Risk per se is not a self-explaining concept that ‘exists’ by its own virtue. Our discussion is therefore based on existing methodologies and epistemological claims concerning risk. With these claims as our point of departure, we examine risk in relation to the concept of time, state of affairs (the state of the world) and events and discuss relations and constitutional issues for the risk concept. Drawing on a relation between time and state of affairs, we argue that risk is rooted in the transition from the future to the present. Risk is being constituted by the transition from a myriad of future possibilities into one present reality (one actual contingent world). This implies that risk is not ontologically something of the future, but rather something of the present. However, we argue that risk does not exist in any ontological sense. What actually exist are possible (future) states of affairs and these may or may not be interpreted to hold risk. An implication of this is that all risk claims are subjective.  相似文献

This article examines the evolution of building societies against a background of environmental change. By the application of specific analytical measures developed by Ansoff five distinct periods of change can be isolated. Key events in the environment have become progressively more novel, less predictable and costlier to deal with, which, in turn, has necessitated both operational and strategic redirection.  相似文献

A group of players in a cooperative game are partners (e.g., as in the form of a union or a joint ownership) if the prospects for cooperation are restricted such that cooperation with players outside the partnership requires the accept of all the partners. The formation of such partnerships through binding agreements may change the game implying that players could have incentives to manipulate a game by forming or dissolving partnerships. The present paper seeks to explore the existence of allocation rules that are immune to this type of manipulation. An allocation rule that distributes the worth of the grand coalition among players is called partnership formation‐proof if it ensures that it is never jointly profitable for any group of players to form a partnership and partnership dissolution‐proof if no group can ever profit from dissolving a partnership. The paper provides results on the existence of such allocation rules for general classes of games as well as more specific results concerning well‐known allocation rules.  相似文献

Research has shown that offshore outsourcing processes may influence the behavior and strategic choices of firms, but little is known about the determining factors that influence the evolution and outcomes of those processes. Furthermore, longitudinal studies able to generate such insights are lacking. This paper suggests a detailed, activity-based approach to the study of the process of offshore outsourcing of high-value, advanced service activities. While earlier research has considered either firm-internal or firm-external sources of resource building, this study offers a more comprehensive theoretical model that combines resource-based theory and international business network theory. It aims to investigate how determinants of the offshore outsourcing process contribute to the resource stocks of client firms. Based on two longitudinal case studies of offshore outsourcing to India, the study finds that offshore outsourcing operations, in general, make positive contributions to the resource stocks of client firms. Some determinants contribute to the building of resources (partnership commitment decisions, knowledge creation and learning, trust building, the interconnectedness of resources) while others impede resource building (time compression diseconomies, lack of resource mass efficiencies). Notably, the interconnectedness among onshore activities, offshore activities and the underpinning knowledge resources reduces the risk of erosion of client firm resources, although this remains a long-term risk.  相似文献

Using the longest data set on foreign exchange (FX) order flow to date, along with the broadest coverage of currencies to date, we examine the effect of FX order flow on exchange rates across small and large currencies, currencies with floating or fixed regimes, and across both tranquil and turbulent periods. Over our 15 years of data for 11 Asian and Australasian currencies, we find that order flow has a potentially strong impact on all exchange rates in the sample. The effect is strongest on floating exchange rates, both economically and statistically, but is sizeable also on the other exchange rates, especially during periods of turbulence. By creating a measure of regional order flow, we show that all exchange rates depreciate as flows are moved out of Asia/Australasia and into US dollars. This is true both across regimes and if their own flow is not included in the structure of the regional flow.  相似文献

We extend the fractionally integrated exponential GARCH (FIEGARCH) model for daily stock return data with long memory in return volatility of Bollerslev and Mikkelsen (1996) by introducing a possible volatility-in-mean effect. To avoid that the long memory property of volatility carries over to returns, we consider a filtered FIEGARCH-in-mean (FIEGARCH-M) effect in the return equation. The filtering of the volatility-in-mean component thus allows the co-existence of long memory in volatility and short memory in returns. We present an application to the daily CRSP value-weighted cum-dividend stock index return series from 1926 through 2006 which documents the empirical relevance of our model. The volatility-in-mean effect is significant, and the FIEGARCH-M model outperforms the original FIEGARCH model and alternative GARCH-type specifications according to standard criteria.  相似文献
