In a recent paper, Jones (1995) [A dynamic analysis of the interfuel substitution in US industrial energy demand. J. Bus. Econ. Stat. 13 (4), 459–465] presents a dynamic analysis of interfuel substitution in US industry energy demand. The author concludes that a dynamic linear logit model is ‘superior' to a comparable dynamic translog model. The latter in fact violates concavity conditions whilst the logit formulation does not. This paper shows first of all that the dynamic formulation of the translog used in Jones (1995) is mis-specified. In fact, a parsimonious error-correction model (ECM) ‘dominates' alternative dynamic formulations, amongst which the partial adjustment mechanism used by the author. The ECM is able to generate optimal estimates of long-run and short-run elasticities, and it satisfies the concavity conditions of the cost function. Further, the theoretical framework used in this paper is the one recently proposed by Urga (1996) [On the identification problem in testing dynamic specification of factor demand equations. Econ. Lett. 52, 205–210] and Allen and Urga (1998) [Derivation and estimation of interrelated factor demands from dynamic cost function. Forthcoming in Economica]. It allows one to identify all coefficients (long-run and short-run) of the dynamic formulation via the joint estimation of the ‘effective' (short-run) cost function and the set of factor demand equations. This strategy solves, amongst other things, the parameter identification problem within the set of demand equations themselves, an issue which was originally noted by Anderson and Blundell (1982) [Estimation and hypothesis testing in dynamic singular equation systems. Econometrica, 1559–1571], re-addressed by Friesen (1992) [Testing dynamic specification of factor demand equations for US manufacturing. Rev. Econ. Stat. LXXIV (2), 240–250] and, more recently, by Urga (1996) and Allen and Urga (1998).  相似文献

The aim of this contribution is to verify whether there exists a reaction of financial markets to the new accounting method for goodwill introduced by SFAS 142 and IAS 36. Our research hypothesis is that financial markets should have no significant reaction to the goodwill write-off following the impairment test, since the latter's outcome represents an economic estimate without financial significance. The hypothesis was checked by the analysis of the companies added to the Standard & Poor's Europe 350 index over a three-year period, taking note of goodwill write-off announcements and relating them with the stock market prices and their volatility. The results demonstrate a correlation between the goodwill write-off and the behaviour of financial markets, while the same connection cannot be evinced for prices volatility. Also, what comes out from our analysis is that markets need a relatively long period, over one semester, before absorbing in full the effects resulting from the write-off announcement.  相似文献

The paper provides a quantitative assessment of the impact on the banana market of the expansion of trade preferences the European Union granted Africa, Caribbean and Pacific (ACP) countries with the Economic Partnership Agreements (EPA) and of the possible erosion of these preferences as a result of different possible conclusions, if any, of on-going WTO negotiations. The results of the simulations performed suggest that the impact of the EPA on production and consumption of bananas in the EU will be limited, while benefits for ACP countries will be significant (at the expense of Most Favoured Nation (MFN) exporters). An agreement between the EU and MFN countries to end the outstanding WTO disputes on bananas and/or the conclusion of the WTO Doha round may bring an erosion of the preferential margins currently enjoyed by ACP countries of such an order of magnitude as to cancel out most of these benefits.  相似文献

The aim of this paper is to present a search model in the field of environmental economics, where so-called clean and dirty producers enter the trading market, both looking for a partner with whom to exchange the goods they are endowed with. The model derived in this paper is rather simple. Nevertheless, it is able to produce a series of interesting results and useful insights, and is conveniently used here as a framework to explain the functioning of Joint Implementation programs for polluting emissions' reduction.  相似文献

Marketing research has a limited understanding about the effects arising from emotional shifts (i.e., the transition from one emotion to another) during the same advertising message. This paper sheds light on this topic through two studies. Study 1 examines whether an advertising message that features a negative-to-positive emotional shift (i.e., a shift from a negative to a positive emotion) generates greater recall of an advertised brand than an advertising message with a neutral-to-positive emotional shift (i.e., a shift from a neutral to a positive emotion) or one with no emotional shift. Study 2 examines whether an advertising message that simulates a buyer-seller encounter—with the seller reproducing a negative-to-positive emotional shift via facial expressions—generates a greater recall of the advertised content than an identical advertisement with no emotional shift. Results confirm that a negative-to-positive shift facilitates the recall of both the brand and the advertised information.  相似文献

In this paper we first show that the timing and skill distribution of Immigrants to the U.S. between 1970 and 2014 imply they did not contribute to the decline in the wages of native, non-college educated workers – including high school dropouts – at the national level. We then review other evidence at the local level, which implies immigration is not associated with lower non-college wages. Rather, higher immigration seems associated with higher average (and college-level) wages. Local externalities, complementarities, efficient specialization and appropriate technological choice suggest at least part of the positive association is causal.  相似文献

One of the key features of our economies consists of the coexistence of different technologies supplying similar products and services. We often observe that an old technology is improved when a new one appears; behind this process of improvement often lies an intentional research activity. There thus begins a competition between the two technologies whose performances are improved via R&D. We focus our attention on this competition process and supply a formal model, based on the optimization of R&D expenditure of both technologies, which can describe the dynamics of the delayed overtaking of the new technology over the old one.  相似文献

This paper studies the effect of intention-based reciprocity preferences on the free-riding problem arising in partnerships. Our results suggest a tendency of efficient partnerships to consist of members whose sensitivity to reciprocity is – individually or jointly – sufficiently high. Sufficient conditions for the implementation of the efficient strategy profile require a reciprocity-based sharing rule so that each partner gets a fraction of the output, which is a percentage of his own sensitivity to reciprocity with respect to the overall sensitivity in the team. Finally, we introduce the concept of psychological strong Nash equilibrium and show that it allows for the unique and collusion-proof implementation of the efficient strategy profile.  相似文献

Moving from the growing relevance of the enterprise risk management (ERM) concept, this paper provides empirical evidence of ERM in practice. The paper presents ERM actual uses in a panel of nine Italian companies from different industrial fields and legislative settings and analyses the relationship between the uses and the characteristics of the ERM tool implemented in each case. The data analysis highlights the existence of different activities that are supported by the ERM tool and also different types of use (i.e. responsive, discoursive and prospective) corresponding to a different contribution of ERM to managerial action. These uses related to the specific characteristics of the tools generally indicated with the label ‘ERM’.  相似文献
