In their bid for integration with the European Union, the countries of Central and Eastern Europe are faced with the need to introduce numerous significant improvements to their economic systems. A highly important role in this process is to make changes in the existing banking systems. The credit risk evaluation method presented here, using taxonomic measures to plot so-called credit risk maps, may be used to develop sound principles of credit policies. It is a proposition that could solve one of the many problems arising in the course of adaptation of banking systems in Central and Eastern Europe to conditions of market economy.  相似文献

This paper presents a PDE approach in a Markovian setting to hedge defaultable derivatives. The arbitrage price and the hedging strategy for an attainable contingent claim are described in terms of solutions of a pair of coupled PDEs. For some standard examples of defaultable claims, we provide explicit formulae for prices and hedging strategies.  相似文献

We explore the country-specific institutional characteristics likely to influence an individual’s decision to become an entrepreneur. We focus on the size of the government, on freedom from corruption and on “market freedom” defined as a cluster of variables related to protection of property rights and regulation. We test these relationships by combining country-level institutional indicators for 47 countries with working-age population survey data taken from the Global Entrepreneurship Monitor. Our results indicate that entrepreneurial entry is inversely related to the size of the government, and more weakly to the extent of corruption. A cluster of institutional indicators representing “market freedom” is only significant in some specifications. Freedom from corruption is significantly related to entrepreneurial entry, especially when the richest countries are removed from the sample, but unlike the size of government, the results on corruption are not confirmed by country-level fixed-effects models.  相似文献

Using a sample of 76 countries, this paper examines the impact of major strikes against government and its policies on stock market behavior. An occurrence of a general strike is detrimental to the value of equities, as documented by the ceteris paribus 6.11% fall in dollar-denominated stock market indices of the affected countries. This event is also accompanied by a statistically significant increase in risk, as measured by the standard deviation of returns and Value-at-Risk metrics. Taken together, these results imply that general strikes have serious ramifications for stock market investors.  相似文献

The fact that value shares outperform glamour shares in the long term has been known for over 50 years. Why then do glamour shares remain popular? The price-earnings (P/E) ratio was the first statistic documented to discriminate between the two. Using data for all US stocks since 1983, we find that glamour shares have a much greater tendency to change P/E decile than value shares. We use TreeAge decision tree software, which has not been applied to problems in finance before, to show that glamour investors cannot rationally expect any windfall as their company's P/E decile changes, whatever their horizon. We infer that glamour investors anchor on the initially high P/E value, underestimate the likelihood of change and are continually surprised. We also seek theoretical justification for why value shares tend to outperform glamour shares. No convincing arguments based on the efficient market hypothesis have been put forward to show that the outperformance of value shares might be due to their being fundamentally riskier. Here, we apply equations from option theory to show that value shares can indeed be expected to outperform glamour shares.  相似文献

The goal of the paper is to propose a method for finding outcomes of negotiations of multiple parties with a multi-criteria decision outcomes evaluation. Firstly, the procedure for reduction of continuous set of options to large but finite crowd of compromise recommendations is presented. Next, the crowd is integrated to a single benchmark which is treated as a proposal of artificial auxiliary player called a lone wolf as presented by Kersten and Szapiro (Proceedings of the international conference of the society of systems and science. Budapest, 1987). The strategy of negotiation with this artificial player is proposed to generate a benchmark evaluations scheme for real negotiation. Finally, a multi-agent simulation approach for multi-lateral negotiation process modeling is presented in order to estimate possible negotiation outcomes.  相似文献

This paper compares the impact of institutions on men and women’s decisions to establish new business start-ups between 2001 and 2006. We use data from the Global Entrepreneurship Monitor survey (GEM) which cover at least 2,000 individuals per year in each of up to 55 countries and have merged it with country-level data, from the World Bank, Economist Intelligence Unit, Polity IV and the Heritage Foundation. We find that women are less likely to undertake entrepreneurial activity in countries where the state sector is larger, but the rule of law is not generally found to have gender-specific effects. However, more detailed institutional components of discrimination against women, in particular, restrictions on freedom of movement away from home, make it less likely for women to have high entrepreneurial aspirations in terms of employment growth, even if their entry into entrepreneurial activities, including self-employment, is not affected by this.  相似文献

In this paper we present the NegoManage system, which aims at supporting the bilateral negotiation during all negotiation phases. The support includes the problem structure identification, the analysis of individual preferences of both parties, the messaging and offers exchange and the post-negotiation improvements of the agreement. The preference analysis is supported with a novel mechanism involving the specification of the classes of alternatives’ quality that represent particular levels of potential satisfaction from accepting this alternative as the negotiation solution. The consistency of preferences is also checked. The actual negotiation phase is performed in a typical way, namely the negotiators exchange multiple offers and messages. The novelty introduced in this phase is the mechanism for profiling the negotiators based on the classification of exchanged messages. The post-negotiation optimization phase employs the concept of a bargaining solution for improving the solution obtained in the previous negotiation phase. We present the way the mechanisms proposed work using simple numerical examples.  相似文献

The aim of the paper is to discuss the concept of cost-effectiveness of national air pollution abatement programmes, analyze it from a region-wide perspective, and outline a framework for integrating international and domestic environmental priorities. The paper refers to air protection policy priorities adopted by the government of Poland in 1990, and reviews policy instruments envisaged for their implementation. Additionally, it discusses international priorities and how the government of Poland attempts to address these in its policy.After defining cost-effectiveness, this paper reviews how the choice of policy instruments influences the costs of pollution control policy. Then, the recent Polish experience with charges, environmental funds, and transferable permits is confronted with the cost-effectiveness principles. The paper concludes that Poland has developed an extensive system of pollution fees which serves a revenue-raising purpose and gives modest incentives to abate, although the cost-effectiveness of this mechanism needs improvement. A potential role for transferable permits is emphasized.  相似文献
