This paper reviews experience with policy reforms in the maize sector in Mexico, beginning in the 1980s with particular reference to impacts on price variability. It analyses Mexico’s transition from past price stabilization policies under a state-trading enterprise to market reforms implemented during the 1990s. The nature, extent, and costs to producers and consumers of maize policies is discussed for both the pre-reform and the reform periods. Although wide ranging reforms have been introduced, impacts on efficiency and fiscal outlays have been less than expected. 相似文献

Measuring financial risks with copulas 总被引:2,自引:0,他引:2
Beatriz Vaz de Melo Mendes Rafael Martins de Souza 《International Review of Financial Analysis》2004,13(1):27-45
This paper is concerned with the statistical modeling of the dependence structure of multivariate financial data using the concept of copulas. We select some special copulas and identify the type of dependency captured by each one. We fit copulas to daily returns and simulate from the fitted models. We compare the effect of the choice of copula on risk measures and assess the variability of one-step-ahead predictions of portfolio losses. We analyze extreme scenarios and fit extreme value copulas to the block maxima and minima from daily returns. The stress scenarios constructed are compared to those obtained using models from the extreme value theory. We illustrate the usefulness of the copula approach using two stock market indexes. 相似文献

This paper aims to thoroughly look into the effects of the differences between the diverse leadership styles on innovative outputs (intensive, efficient and eco-efficient) in Spanish industrial companies. A questionnaire for the factories was sent and was received between the months of September 2013 and June 2014. A total of 142 valid questionnaires were received. Several regression models were used in the empirical analysis. The results show that charismatic leadership positively induces an intensive innovative output, at the same time as it improves firms’ eco-efficient innovative output. Likewise, the individualised consideration that characterises transformational leadership makes this leadership style produce positive results on the whole group of innovative outputs considered. At the other end of the leadership spectrum, the transactional style causes negative effects on the relationship between innovative activity and innovative outputs, and more specifically, on the efficient innovative output. 相似文献

Institutional investors show increasing interest in how companies align their corporate social responsibility strategies with the sustainable development goals (SDGs) proposed by the United Nations (UN). The information disclosed in this regard is essential to know and monitor business contribution to the 2030 Agenda. In this paper, we analyze the influence that institutional investors have on the adoption of the disclosure strategy established by UN and the Global Reporting Initiative (GRI)—GRI‐SDG Compass. The results obtained for a sample of 989 international companies, which prepare their sustainability reports following the GRI guidelines, show that ownership by foreign investors, pension funds, and “other” investors boosts the relevance of the information disclosed in relation to the 2030 Agenda. On the contrary, government, financial institutions, and cross holdings have no impact on the information systems developed. 相似文献

From the point of view of firms’ managers, the knowledge of the factors which explain their firms’ financial results is considered of great usefulness to propose the most appropriate and profitable marketing strategies and actions. This research sets out from this central idea and proposes a model of relationships that considers the marketing results, the marketing capabilities, and the innovation capability as key factors for achieving good financial results. This model is verified via an empirical investigation carried out among 200 directors of hotel establishments in Andalusia, a region in the south of Spain which is one of the country's main tourist destinations. The results indicate that innovation capability is strongly conditioned by marketing capabilities and resources and that this innovation capability affects the financial results of the firms analyzed. Likewise, it is deduced that a market-oriented management philosophy contributes to the development of these marketing capabilities. The implications for management are considered very relevant as they must lead these firms to invest in the development of marketing resources and capabilities, and apply a market-oriented management philosophy if they wish to improve their financial results. 相似文献

This paper aims to examine the usefulness of sustainability reporting in reducing information asymmetry as result of lower dispersion and higher accuracy in financial analysts’ earnings forecasts. The empirical results from an international sample of listed companies indicate that the disclosure of sustainability information alone is not sufficient in this regard as our findings indicate that information asymmetry is reduced to a greater when such information is assured, supporting the value relevance role of sustainability reporting and assurance. In addition, the empirical findings suggest differences in terms of assurance attributes (provider and level of engagement) and such differences are even more relevant when controlling the institutional context. Assurance is highly appreciated by investors in more stakeholder-oriented countries; however, in more shareholder-oriented environments, assurance affects information asymmetries only when it is provided by accounting professionals who also report a “reasonable” opinion. 相似文献

In this article, we describe the methods employed and the results obtained from a mixed-mode “sensitive research” conducted in Spain to estimate certain aspects concerning patterns of cannabis consumption and sexual addiction among university students. Three different data-collection methods are considered and compared: direct questioning, randomized response technique and item sum technique. It is shown that posing direct questions to obtain sensitive data produces significantly lower estimates of the surveyed characteristics than do indirect questioning methods. From the analysis, it emerges that male students seem to be more affected by sex addiction than female students while for cannabis consumption there is no evidence of a predominant gender effect. 相似文献

This paper studies the international transmission of productivity and monetary shocks in a general equilibrium two-country monetary model with portfolio rigidities and distribution costs in trade. The model features two types of transport costs (iceberg costs and distribution costs in terms of nontradables) and incomplete markets. The specification employed here is able to generate the domestic liquidity effect, increase in the foreign–domestic interest rate differential, and the nominal depreciation after a monetary injection. Quantitatively, the model with distribution costs as in Burstein, Neves and Rebelo (2003) performs better matching some business cycle moments, but fails to generate the high volatility of exchange rates observed in the data. 相似文献

Despite the recent popularity of multi-scale scenario exercises, a review of the literature reveals missing elements regarding local-scale scenario-building. Scenarios built at the local level are often downscaled from higher-scale scenarios or developed within the boundary conditions of global and national scales without taking local circumstances thoroughly into account. On this background, this paper discusses the issue of scale in local scenario development and develops a formal methodological approach for local-scale scenario-building in general. The paper underlines in particular the role of local agency in coupling the larger scale and the local scale. To better illustrate how the proposed approach helps in designing local scenarios, lessons drawn from two local scenario development practices are also employed. Hence, the paper contributes to the formalisation of local scenario-building, which is believed to enhance the validity and credibility of local scenario outputs in the policy sphere. 相似文献

Countries with oil and other natural resources have grown less rapidly than those countries without. This phenomenon is known as the “natural resource curse”. We develop an infinite-horizon, two-country model of trade in which countries are identical, except that one country is endowed with deposits of an exhaustible resource and the other is not. Within the context of the model, we show that this phenomenon can be explained in part by an inelastic demand for the exhaustible resource that increases growth in trade revenues and induces the resource-abundant country to invest relatively less than the country lacking in exhaustible resources. These results are derived analytically and illustrated by an empirical analysis based on plausible parameters obtained from data. 相似文献
