In this paper we develop simulation techniques in order to evaluate single and double barrier options with general features. Our method is based on Sharp Large Deviation estimates, which allow one to improve the usual Monte Carlo procedure. Numerical results are provided and show the validity of the proposed simulation algorithm. 相似文献

In traditional trade models, whether based on technological differences or on relative factor endowments, merchandise composition and directions of trade are derived from closed‐economy conditions. But nowadays one of the basic assumptions of traditional trade models, i.e. that production processes are integrated within just one country, is being increasingly violated as previously integrated productive activities are segmented and spread over an international network of production sites: as a result, an increasingly large share of trade flows is made up of intermediate and unfinished goods being transferred from one country to another in order to be processed. In this paper we submit that such new configuration of production processes has important effects on at least three dimensions of economic research. First, we show that international disintegration of production processes leads to a lessening of the power of comparative advantages when it comes to explaining both merchandise composition and directions of trade, while it is the concept of absolute advantage to become increasingly relevant; second, we show that empirical measures of revealed comparative advantages are inherently misleading if they do not account for differences in the stage‐of‐processing of traded goods; third, we estimate a simple model of aggregate demand accounting for international trade in intermediates: results of estimation lend support to our prior that participation of a country in the process of international fragmentation of production plays a specific and significant role in determining its year‐over‐year change in GDP. 相似文献

This paper investigates whether securities class actions (SCAs) can play a role in banking supervision, both as a warning signal of insolvency and as an instrument of market discipline to encourage bank managers to carefully evaluate risk. Two groups of US banks are compared over the 2000–2008 period. One includes banks that have faced at least one SCA, while the other is composed of non-targeted banks (control group). Results indicate that collective private litigation procedures are more frequently directed at financially fragile intermediaries exhibiting inadequate governance standards. Furthermore, banks which have been subjected to SCAs are likely to reduce their excessive risk positions. This supports the idea that SCAs could be efficiently employed as a complement to public supervisory activity in the banking sector. 相似文献

The present paper addresses the issue of the determinants of the growth of multinational banks upon foreign markets at a micro individual level. Theories and approaches suggested so far about globalisation of the banking sector basically relate banks' international growth to the theory of the multinational enterprise. Accordingly, this paper relies on the eclectic paradigm, which views the foreign direct investment decision to be a combination of ownership, internalisation and location advantages. Empirical evidence is provided through an econometric model based on count data techniques, with reference to the Italian case in the decade 1989–1999. Results show that the availability of resources and international experience already gathered by the parent banks have positive effects on their decision to undertake direct investments abroad. Multinational banks are also proved to grow internationally in order to internalise their pre-existing bank–client relationships, and to locate their foreign units where they can exploit positive externalities related to the presence of important international financial centres. 相似文献

After reviewing the main EU policy documents on the plastic waste issue, this work conceptualises an analysis framework to investigate farmers' attitudes to market‐based tools (i.e., subsidies, tax‐credits, and payback mechanisms in extended producer responsibility schemes) through which the introduction of an operational scheme for a better management of their plastic waste can be incentivised in line with the 2018 European Strategy for Plastics in a Circular Economy. A total number of 1,783 farmers responded to a purpose‐built questionnaire. Results show that most of the plastic waste they produce is piping and packaging and that tax credit represents their most favoured incentivising tool. 相似文献

A Dynamic Model for International Environmental Agreements 总被引:2,自引:1,他引:1
In this paper we develop a model that uses a dynamic framework to analyze the process through which countries join international
environmental agreements (IEAs). In the model, while all countries suffer from the same environmental damage as a result of
total global emissions, non-signatory countries decide on their emission levels by maximizing their own welfare, whereas signatory
countries decide on their emission levels by maximizing the aggregate welfare of all signatory countries. It is assumed that
signatory countries will be able to punish non-signatories, at some cost to themselves. When countries decide on their pollution
emissions, they account for the evolution of the stock of pollution over time. Moreover, we propose a mechanism to describe
how countries reach a stable IEA. The model is able to capture situations characterized by partial cooperation within an IEA
that is stable over time. It also captures situations where all countries participate in a stable agreement, and situations
where no stable agreement is feasible. Where more than one possibility coexist, the long-term outcome of the game depends
on the initial conditions (i.e., the initial number of signatory countries and pollution level). 相似文献
