Summary. This article considers a two-sector model of economic growth with “labour-augmenting” intersectoral external effects stemming
from the aggregate capital stock. It is shown that equilibrium balanced growth paths with a non-trivial labour allocation
scheme become available. A set of sufficient conditions for the existence of multiple equilibrium growth rays is provided
and their determinacy properties are then characterised. Finally, examination of a parameterised C.E.S. economy illustrates
the central role of non-unitary values for the elasticity of substitution in the multiplicity issue.

We consider a partial equilibrium model to study the optimal phasing out of polluting goods by green goods. The unit production cost of the green goods involves convexity and learning-by-doing. The total cost for the social planner includes the private cost of production and the social cost of carbon, assumed to be exogenous and growing at the social discount rate. Under these assumptions the optimization problem can be decomposed in two questions: (i) when to launch a given schedule; (ii) at which rate the transition should be completed that is, the design of a transition schedule as such. The first question can be solved using a simple indicator interpreted as the MAC of the whole schedule, possibly non optimal. The case of hydrogen vehicle (Fuel Cell Electric Vehicles) offers an illustration of our results. Using data from the German market we show that the 2015–2050 trajectory foreseen by the industry would be consistent with a carbon price at 52€/t. The transition cost to achieve a 7.5 M car park in 2050 is estimated at 21.6 billion € that is, to JEl 4% discount rate, 115 € annually for each vehicle which would abate 2.18 tCO\(_2\) per year. 相似文献

The trade imbalance between Japan and its Western partners may be a source of concern, but much more serious is the even far greater investment imbalance. While Japanese direct investments have poured into the North American and European markets, American and European investments in Japan are paltry: the current ratio of investment flows is running at 20 to 1, in some cases much more, in Japan's favour. As the strategic issues for Western companies in establishing a "robust presence" in Japan are fundamental and critical, the trade and investment deficits are partly caused and further exacerbated by the "knowledge-gap" between the two. Reversing the scorecard must be the most urgent imperative for Western corporations and governments, though the effort required will be very substantial indeed. 相似文献

Abstract Changes over the last few decades in managing risk and investing money have been so radical that we can only describe them as being huge disruptions, maybe even revolutions. The boundaries that used to exist between the different financial activities have disappeared. Although things have accelerated rapidly over the last few decades, we should keep in mind that these developments are by no means new. The pawnbrokers and foreign exchange dealers of the Middle Ages, whose professions were separate and clearly identifiable, have seen their activities completely integrated into so-called universal banking services. More recently, merchant banks in France, who used to be the subject of specific regulation, have disappeared as separate legal entities. In the insurance field, it was barely 30 years ago, that some large businesses insured only against fire risks and others only casualty risks. The distinction between life and non-life, which is still maintained in the regulations, makes little sense in the everyday reality of insurance groups who transact these two activities together. However, when we talk of the integration of financial services, we have in mind an even more recent phenomenon. Financial integration incorporates two developments, known in French as bancassurance and assurfinance. Today, under extremely diverse legal guises but following the same economic logic, banks sell insurance products and insurance networks sell banking products. This movement can only be understood initially as the result of a need to diversify. Each one of these two large categories of financial intermediaries borrowed something from the other in order to increase its product range or bolster the know-how of its networks. It was simply about making sales organizations more cost effective by having them sell products outside of their traditional skills area, at more or less marginal cost. Today the expansion of offerings is done, approved, and even expounded on by theorists. And so now the next question is whether we should go further—turning our attention from distribution to manufacturing. This is where the current debate on the integration of financial services lies. Bluntly, if we allow banks to sell insurance policies and insurers to sell consumer credit, should we allow a joint organization to design such products and distribute them down both channels at the same time? More subtly, we might ask ourselves whether we should be exercising more specific control over these financial conglomerates that, while maintaining a formal legal separation between banking and insurance, constitute in fact a single decision-making center. This article sets out to portray what is perhaps not the state of the law, but at least the state of the art, on this topic in the European Union. In the first part, it will show that while sales integration is an undeniable fact, with the customer seeing fewer and fewer differences, it still remains that banks and insurance carriers are separate entities from a legal perspective and that the European Union remains totally committed to controlling financial conglomerates. In practice, integration of financial services takes different forms. In part two, we examine cases involving problems between entities doing the same job, and cooperation between design facilities without any apparent desire to go further. In the long run, this integration will succeed only if it receives the public?s approval. Part three addresses what consumers and investors want. We observe that after decades of exposure to specialized networks, consumers are not necessarily as enthusiastic as proponents of integration would have hoped. As adult consumers, they are not prepared to buy just any financial service anywhere they can, and they still largely place their trust in the brands they know. 相似文献

There is scarce research on the influence of the level of consumer involvement with wine and consumption-elicited emotions. In this context, we aim to examine whether the level of wine involvement influences the emotional response; and further, whether the level of wine involvement plays a determining role in how emotions drive satisfaction. The study involved a convenience sample through a restaurant and bar intercept survey conducted in La Rioja (Spain). Subsequently, three levels of consumer involvement with wine were examined: low (n?=?316), medium (n?=?387) and highly involved consumers (n?=?462). Then, data were analyzed through structural equation modelling (SEM). Our findings indicate that differing levels of consumer involvement with wine lead to different emotions and satisfaction. Further, consumers should surpass an “involvement threshold” in order to develop a negative emotional appraisal and to provoke negative affect towards wine; but this “involvement threshold” does not apply to the development of pleasant emotions. 相似文献

This paper provides some theoretical grounds to relate asymmetries in cost structures and incentives towards price competition. Typically low cost firms favor price competition whereas the reserve is true for high cost firms. Increased price competition will tend to diminish price-cost margins for all firms but the low cost firms may increase their total profits through an enlarged market share. This analysis depends on two relevant parameters: the way the overall market will react to increased price competition and interfirm cross elasticities. This is proved using comparative statics at the Nash equilibrium of an oligopolistic model. 相似文献

A reciprocity-based model of wage determination is incorporated into a modern dynamic general equilibrium framework and estimated on U.S. data. The estimation reveals that rent-sharing (between workers and firms) and wage entitlement (based on past wages) are important determinants of wage setting for the model to fit the dynamic responses of output, wages and inflation to various exogenous shocks. Aggregate employment conditions (measuring workers’ outside option), on the other hand, are found to play only a negligible role for wage setting. These results are consistent with micro-studies on reciprocity in labor relations but contrast with traditional efficiency wage models which emphasize aggregate labor market variables as the determinants of wage setting. 相似文献
