Exchange Rate and Interest Rate Polarization. - The relationship between the polarization phenomenon in foreign exhange markets and a similar regu-larity in interest rate differentials is considered. In the case of perfect substitutability and of perfect foresight, both polarizations would be perfectly complementary. Risk premia and forecast errors, however, might induce some degree of substitutability between the two concepts. Throughout almost the entire EMS experience, in France and Italy both phenomena appear to be equivalent. At the end of the 80s, however, interest rate polarization has surged at the expense of exchange rate polarization. In fact, a bias in estimates was found to explain this recent behaviour. 相似文献

The world’s press may have lost interest in the ongoing enquiry into the deep-rooted corruption in Italian business. But what exactly was going on, and what can be done to improve matters? The writers of this authoritative study are Faculty members of the prestigious Italian Business School, SDA Bocconi, Via F. Bocconi 8, 8-20136 Milano, where Umberto Lago lectures in Strategy and Roberto Castoldi in Accounting. They both lecture on the Business Policy course at Bocconi University. 相似文献

In this paper, we apply a copula function pricing technique to the evaluation of credit derivatives, namely a vulnerable default put option and a credit switch. Also in this case, copulas enable one to separate the specification of marginal default probabilities from their dependence structure. Their use is based here on no–arbitrage arguments, which provide pricing bounds and easy–to–implement super–replication strategies.
At a second stage, we specify the copula function to be a mixture one. In this case, we obtain closed form prices and hedges, which we calibrate on real market data. For the sake of comparison, we add a Clayton calibration.

We provide general results for the dependence structure of running maxima (minima) of sets of variables in a model based on (i) Markov dynamics; (ii) no Granger causality; (iii) cross-section dependence. At the time series level, we derive recursive formulas for running minima and maxima. These formulas enable to use a "bootstrapping" technique to recursively recover the pricing kernels of barrier options from those of the corresponding European options. We also show that the dependence formulas for running maxima (minima) are completely defined from the copula function representing dependence among levels at the terminal date. The result is applied to multivariate discrete barrier digital products. Barrier Altiplanos are simply priced by (i) bootstrapping the price of univariate barrier products; (ii) evaluating a European Altiplano with these values. 相似文献

Countries’ image is a multifaceted construct. Its symbolic dimensions have shown to play an important role both on consumer behavior and on the attraction that organizations can have during the recruitment process. This paper offers a comprehensive model of international mobility decisions encompassing the antecedents and consequences of perceptions about emerging economies, proposing that country image depends on individuals’ background and social identities. In this context, countries’ evaluations can play a major role on influencing the willingness to accept expatriate job offers. We used a within-subject design asking for opinions about hypothetical job offers on six particular host countries: Algeria, Democratic Republic of Congo, Argentina, Chile, Angola and Mozambique. Survey results from more than 500 engineers, (125 French nationals, 121 Spanish and 131 Portuguese, with the remaining 138 coming from 42 different countries, yet working in 1 of the 3 above-mentioned European countries), evidence, that language proficiency influences the evaluation of specific expatriate locations. Our results also convey the critical role of the perceived level of safety and cultural attraction in predicting the willingness to accept expatriate job offers. We conclude by discussing the theoretical and practical implications for human resource management. 相似文献

In this note, we analyze the local dynamics of a general non-linear fixedprice disequilibrium IS-LM model. We assume investment
behavior as a general nonlinear function avoiding any Kaldor type assumption. By proving the existence of a family of periodic
solutions bifurcating from a steady state, we confirm and extend some results in the literature for IS-LM models reducible
to Leinard’s equation. We use bifurcation theory and study the effect of a change of the adjustment parameter in the money
market upon the solutions of the model as the steady state loses stability.
We establish analytically that the values of the adjustment parameter in the money market may affect the equilibrium relative
to the product market and the government budget constraint. (JEL: C62, E32) 相似文献

Although new paint products and technologies have been developed, the sector of paint application still contributes substantially to total volatile organic compound (VOC) emissions. Recent environmental legislation, especially the EU Solvent Emission Directive 1999/13/EC and its transposition into national law, coming into force in 2007, will have an important influence on the sector structure and the associated supply chain, especially for small- and medium-sized enterprises (SMEs). This paper summarises a comprehensive scenario analysis to explore possible future trajectories for the sector. The main focus is on paint application activities, considering in particular the consequences of new environmentally friendly products and technologies which can be used by SMEs. Four different scenarios representing possible future states of the sector are evaluated, taking into account environmental, technical and socio-economic aspects along the associated supply chain and life cycle. The scenarios allow the formulation of recommendations and guidelines for policy makers and industries. This example confirms that interdisciplinary scenario analysis is a suitable approach to investigate possible future development of an industrial sector. 相似文献

In this paper a proof is offered that if a variable Y3 does not cause a variable Y1 in the bivariate system (Y1, Y3) and Y3 causes a variable Y1 in higher-order system (Y1, Y2, Y3), then the omitted variable Y2 must cause the variable Y1 in the bivariate system (Y1, Y2) and in the trivariate system (Y1, Y2, Y3). 相似文献
