Asymmetric Reaction Functions for the Euro Area 总被引:2,自引:0,他引:2
This paper offers a preliminary evaluation of ECB conduct ofmonetary policy by estimating a fairly general reaction functionfor the euro area. The specification of the policy rule embodiesa number of nonlinearities which are shown to stem from asymmetricpreferences and a convex aggregate supply curve. Asymmetricpreferences allow, but do not require, policy-makers to weightdifferently positive and negative deviations of inflation andoutput from the reference values, and translate into an asymmetricreaction function. The empirical analysis on monthly euro-areaaggregated data over the last 5 years reveals that ECB monetarypolicy is effectively described by a nonlinear policy rule accordingto which output contractions have required a larger policy responsethan output expansions. Moreover, actual movements in the eurointerest rate closely resemble the simulated path that a Bundesbank-typeof behaviour would have implied. 相似文献

The growth of European-scale companies represents a further centralisation of management organisation in large enterprises. But processes of decentralisation are also evident. Implications of these opposing trends for labour relations are unclear. Taking account of differences between national systems, the article considers two paths that management approaches could follow. 相似文献

We argue that a trade agreement which conforms to GATT’s reciprocity rule benefits the (stronger) less trade‐dependent country at the expense of the (weaker) more trade‐dependent country. Reciprocity is so unfavorable to the weaker country that it may be worse off under reciprocity than under the Nash‐ bargaining solution, a “power‐based” approach to trade negotiations that reflects power asymmetries among trading partners. Our results question Bagwell and Staiger’s (1999 , 2000 ) view of reciprocity as a rule that “serves to mitigate the influence of power asymmetries on negotiated outcomes.” 相似文献

This paper is based on the results of a field work analysis of the cotton weaving industry, focusing on the relationships between performance, size and structure of firms. The results are utilized to compare models of the industries in the main European countries and to evaluate their competitiveness in the light of both standard and some non-standard efficiency criteria. 相似文献

In their very interesting paper “Set-packing problems and threshold graphs” [1] V. Chvatal and P. L. Hammer have shown that the constraints $$\begin{gathered} \sum\limits_{j = 1}^n {a_{ij} x_j \leqslant 1(i = 1,2, . . . , m)} \hfill \\ x_j \in (0,1)(j = 1,2, . . . , n) \hfill \\ \end{gathered} $$ are equivalent to the only inequality $$\begin{gathered} \sum\limits_{j - 1}^n {c_j x_j \leqslant d} \hfill \\ x_j \in (0,1)(j = 1,2, . . . , n) \hfill \\ \end{gathered} $$ if and only if the intersection graph associated with the matrix (a ij ) — see § 1 — is a threshold graph i.e. a graph none of whose induced subgraphs are isomorphic to 2K 2,P 4,C 4: As Chvatal and Hammer have shown [1], threshold graphs can be characterised in many different ways; the main result of this paper is to give a new, very simple characterisation which will enable us to test whether a graph is a threshold by a simple inspection of its incidence matrix. 相似文献

It is well documented that a firm may choose to offer underpriced securities in an initial public offer. An open question is why investment banks do not retain underpriced offers in their portfolio. We argue that the distribution of underpriced securities allows banks of high qualify to signal their value to their customers, promoting in this way their other product lines. We show that the total dollar value of underpriced securities distributed (rather than the percentage value) acts as the signal. We also find that, all else equal, larger customers and those with more elastic demand functions receive n larger total dollar value of underpricing. 相似文献

In this study we develop a new methodological proposal to incorporate risk into a farm‐level positive mathematical programming (PMP) model. We estimate simultaneously the farm nonlinear cost function and a farmer‐specific coefficient of absolute risk aversion as well as the resource shadow prices. The model is applied to a sample of representative arable crop farms from the Emilia‐Romagna region in Italy. The estimation results confirm the calibration ability of the model and reveal the values of the individual risk aversion coefficients. We use the model to simulate different scenarios of crop price volatility, in order to explore the potential risk management role of an agri‐environmental scheme. 相似文献

This study about Italian producers of machines and plants for pasta, basic cereals, snacks and bread factories attempts to shed some light on the role played by small and medium-sized enterprises (SMEs) in the Italian industry. Even if the high diffusion of SMEs has positively affected the performance of Italian economy during the seventies and the eighties, the new trends of technological change and global competition are expected to be unfavourable to this category of enterprises in the nineties. The analyses of a significant sample of firms makes clear that the industry is in the middle of a positive restructuring process. The structure of this sector shows a division of labour based on deverticalization of production, and a process of internationalization focused on exports and not on direct investments or joint ventures abroad. Leading firms are following growth strategies by new investments and acquisitions. Finally, as far as technological change is concerned, there is a significant increase of process innovations, thanks to the use of electronic components.An earlier release of this paper was presented at 7th EARIE (European Association for Research in Industrial Economics) Annual Conference in Lisbon, September 2–4 1990. We thank all the participants for their comments and suggestions, in particular P. Dunne. 相似文献
