Armington elasticities in intermediate inputs trade: a problem in using multilateral trade data 总被引:3,自引:0,他引:3
Mika Saito 《The Canadian journal of economics》2004,37(4):1097-1117
Abstract. In this paper we find that the estimates of Armington elasticities (the elasticity of substitution between groups of products identified by country of origin) obtained from multilateral trade data can differ from those obtained from bilateral trade data. In particular, the former tends to be higher than the latter when trade consists largely of intermediate inputs. Given that the variety of intermediate inputs traded across borders is increasing rapidly and that the effect of this increase is not adequately captured in multilateral trade data, the evidence shows that the employment of multilateral trade data to estimate Armington elasticities needs caution.

Asymptotic turnpike theorems in the case where the future is discounted are traditionally derived under the assumptions that a utility function is twice differentiable and that is Hessian is negative definite. Replacing these assumptions by a weaker one. I give a proof of the theorem simpler than existing ones. 相似文献

We consider the effects of free entry on the market structure and social welfare of an asymmetric Cournot oligopoly. Even if we allow for the existence of different types of firms initially, only one type (in almost all cases) can survive in the long run. Free entry leads an economy to a symmetric equilibrium, in which the excess entry theorem holds. Further, we consider the socially optimal policy for this economy. In cases of either (i) a concave demand (which implies strategic substitutability) or (ii) strategic complementarity (which implies a convex demand), the type of firms that should remain in the market to achieve social optimality does not necessarily coincide with the type of firms that will survive in the long run. The market may select not only the wrong number of firms but also the wrong type of firms in the long run. 相似文献

Endogenous price leadership and technological differences 总被引:2,自引:1,他引:1
This study constructs a two-stage game of price leadership in a duopolistic market for a homogeneous product. In the first period, the two firms determine a price leader; they set a price for the product in the second period. It is demonstrated in the present study that the technologically superior firm tends to become a price leader. This result reveals that price leadership is determined by the interaction of "competitive force", which prevents the price leader from choosing too high a price (like the joint profit maximizing price or the cartel price), and "collusive force", which prevents a price from falling to a Bertrand price. 相似文献

This paper examines the effects of an export tax (on a processed resource good), the number of harvesters and an afforestation policy in a small, open economy with urban unemployment. The export tax increases the urban unemployment rate, but improves the quality of the environment. Here, the optimal export tax is lower than the adjusted marginal environmental damage. Reducing the number of harvesters has a similar resource allocation effect to that of an export tax. However, the afforestation policy can resolve the trade‐off between urban unemployment and the quality of the environment and may also improve the welfare of a country. 相似文献

This article investigates the effect of banks’ lending capacity on firms’ investment. To identify exogenous shocks to loan supply, we utilize the natural experiment provided by Japan's Great Hanshin‐Awaji earthquake in 1995. Using a unique data set that allows us to identify firms and banks in the earthquake‐affected areas, we find that the investment ratio of firms located outside the earthquake‐affected areas but having a main bank inside the areas was significantly smaller than that of firms located outside the areas and having a main bank outside the areas. Our findings suggest that loan supply shocks affect firm investment. 相似文献

In the present article, we examined the effects of the plan-do-check-act (PDCA) cycle and on-the-job-training (OJT) on workplace learning. We defined workplace learning based on the concept of an organizational learning cycle. Using survey data from a Japanese fire and marine insurance company, we found that PDCA, OJT (empowerment), and reflective communication had positive effects on workplace learning. These results suggest that quality management, empowerment and reflective practice may help to significantly improve workplace learning. We also discuss theoretical and managerial implications of this study. 相似文献
