This is a study of how contractual mechanisms can mitigate agency conflicts in sub-advised mutual funds. Sub-advising contracts allow fund families to expand their product offerings to include new investment styles and thereby gain market share. We show that costly contractual arrangements, such as co-branding, multi-advising, and performance-based compensation, can mitigate agency conflicts in outsourcing and protect investors from potential underperformance. Fund families will find it cost-effective to implement such incentive mechanisms only when investors are sophisticated in assessing manager skill. The findings help to explain why a large percentage of fund families outsource their funds to advisory firms.  相似文献

This article develops a formal model that accounts for the net effect of an exchange rate devaluation on the long-term balance-of-payments constrained growth rate. Such a model investigates how a currency devaluation impacts on the home country non-price competitiveness via changes in income distribution and the rate of technological innovation. The model is built upon two plausible hypotheses. First, it is assumed that the rate of technological innovation is directly related to the income elasticity of demand for exports and inversely related to the income elasticity of demand for imports. Second, it is assumed that a redistribution of income between labor and capital has an ambiguous direct impact on the income elasticities ratio. The model shows that the net impact of a currency devaluation on growth can go either way depending on the institutional framework of the economy.  相似文献

Equity default swaps (EDS) are hybrid credit-equity products that provide a bridge from credit default swaps (CDS) to equity derivatives with barriers. This paper develops an analytical solution to the EDS pricing problem under the jump-to-default extended constant elasticity of variance model (JDCEV) of Carr and Linetsky. Mathematically, we obtain an analytical solution to the first passage time problem for the JDCEV diffusion process with killing. In particular, we obtain analytical results for the present values of the protection payoff at the triggering event, periodic premium payments up to the triggering event, and the interest accrued from the previous periodic premium payment up to the triggering event, and we determine arbitrage-free equity default swap rates and compare them with CDS rates. Generally, the EDS rate is strictly greater than the corresponding CDS rate. However, when the triggering barrier is set to be a low percentage of the initial stock price and the volatility of the underlying firm’s stock price is moderate, the EDS and CDS rates are quite close. Given the current movement to list CDS contracts on organized derivatives exchanges to alleviate the problems with the counterparty risk and the opacity of over-the-counter CDS trading, we argue that EDS contracts with low triggering barriers may prove to be an interesting alternative to CDS contracts, offering some advantages due to the unambiguity, and transparency of the triggering event based on the observable stock price.  相似文献

We model credit rating histories as continuous-time discrete-state Markov processes. Infrequent monitoring of the debtors’ solvency will result in erroneous observations of the rating transition times, and consequently in biased parameter estimates. We develop a score test against such measurement errors in the transition data that is independent of the error distribution. We derive the asymptotic χ2χ2-distribution for the test statistic under the null by stochastic limit theory. The test is applied to an international corporate portfolio, while accounting for economic and debtor-specific covariates. The test indicates that measurement errors in the transition times are a real problem in practice.  相似文献

The aim of this paper is to analyse, through a theoretical model, the effects that the trade integration of two countries may have on industrial location, growth and welfare.The conclusions reached finally depend both on whether the import or the export costs are affected by the trade policies on which the integration process is based and on whether the rich or the poor country introduces them. In general, when integration leads to an increase of industrial concentration in the rich country, the growth rate increases and welfare improves in both countries. If integration means that industry moves to the poor country, the growth rate decreases; in spite of this, in this case the poor country can also improve its welfare.  相似文献

The practice of financial risk management with derivatives has received attention both from the academia and the market. In Brazil, there is a growing use of these instruments by companies, in line with the growth of such market in the global economy. This article aims to investigate the relationship between the financial risk management and the value creation to the shareholder for non-financial Brazilian companies. The sample was made up of 1794 firm-year observations from 2006 to 2014. Results obtained via panel data, including the GMM, point out that companies which used derivatives did not add value during the period analysed. An explanation for this result is that most of the companies use derivatives in order to manage the cash flow and not to add value.  相似文献

Using a panel of firm‐level data from Spanish manufacturers, this study shows that better service regulation reduces the price of intermediate inputs paid by downstream firms. The beneficial cost effects of services reforms extend to both large and small‐to‐medium sized corporations (SME’s), but the former tend to enjoy greater gains. This feature also manifests itself in international markets. We find evidence of an input cost channel through which service regulations affect the volume of exports of large manufacturers, while the evidence of such a channel is weaker for SME’s. Our estimates indicate that, from 1991 to 2007, large firms increased their volume of exports by an average of 20 per cent as a result of the direct input cost effect of services reforms, such that the firms that benefited the most typically belonged to industries more dependent on service inputs. Furthermore, convergence to the ‘best practice’ regulatory framework in services would have raised exports at least by an additional nine per cent. We conclude that firm size is relevant for the connection between services reforms, intermediate input prices and export volumes.  相似文献

For decades, the analysis of public spheres has been a core field in communication science and neighboring disciplines. Its special importance is grounded in the assumption that the public sphere is the primary realm of societal self-understanding, a sphere in which collectively relevant issues, potential solutions and the activity of political and other stakeholders is discussed and put up for scrutiny and legitimization. In much of this research, the media have played a key role, as they were seen as the generally accessible, permanent and comprehensive “master forum” of the public sphere.In recent years, however, scholarship on the public sphere has undergone a “major theoretical shift”, namely, a widening of the analytical perspective from national to transnational concepts of public spheres. Against the backdrop of a general transnationalization of the social sphere, communication scholars have increasingly paid attention to transnational forms of public sphere(s). Many of them, however, have focused on the (potential) emergence of a European public sphere in light of the expansion of the European Union, and only recently has research started to address transnational public spheres beyond Europe.This study ties in with this field of research. An empirical analysis of (potential) transnational public spheres was conducted by focusing on a subject which has been interpreted as a focal point for the emergence of a transnational or even global public sphere: international climate change policy. Due to its high priority and wide reach, international climate policy is said to constitute conditions conducive for a potential transnationalization of public spheres.We understand transnationalization as a pervasion of national public spheres with transnational references that can be distinguished along two analytical dimensions: “Vertical” transnationalization describes the extent to which organizations and actors representing a form of supranational governance are represented and/or (de)legitimized in national public spheres. The “horizontal” transnationalization describes the extent to which organizations or actors from foreign countries are represented within national public spheres.In addition, we differentiate a “strong” and “weak” variant of vertical resp. horizontal transnationalization. For example, a “weak vertical transnationalization” characterizes a case where supranational governance institutions are merely mentioned within a national public sphere; whereas a “strong vertical transnationalization” characterizes a situation where actors from supranational governance institutions have the opportunity to actively express themselves.Our main research questions are 1) to what extent is the media coverage about climate policy in the examined countries pervaded by transnational references? 2) Which patterns of transnationalization can be identified in the media coverage about climate policy in the examined countries?We conducted a manual as well as an automated quantitative content analysis of newspaper coverage about climate change policy in 15 countries. We analyzed 4955 news articles from quality, tabloid and local newspapers for the whole year of 2014. The articles were downloaded from databases like LexisNexis and Factiva, using a complex search string in four languages. The automated content analysis—used to identify the weak variant of transnationalization—followed the “dictionary approach”, with dictionaries based on elaborated word lists (in German and English) that were translated into Portuguese and Spanish and further adapted for this study. The results of the automated content analysis were tested against a manual analysis of 50 randomly selected articles, with very good reliability for each language-specific dictionary (Krippendorff’s Alpha above 0.909). Regarding the manual content analysis—used to identify the strong variant of transnationalization—11 coders were trained and achieved a satisfying to good reliability (Krippendorff’s Alpha above 0.72).Firstly, our analysis shows a visible transnationalization of public debates about climate change policy. In all countries, foreign and supranational actors dominate the domestic news coverage (weak pattern). Conversely, regarding the strong pattern of transnationalization national actors who actively express themselves are dominant.Secondly, our findings show that the transnationalization of the public sphere differs depending on the dimension examined. On the one hand, the horizontal transnationalization appears more often than the vertical one: References to actors from other countries in climate policy-related debates appear more often than references to supranational institutions. On the other hand, transnational references tend to appear rather in a weak than a strong pattern: Foreign or supranational actors are mentioned more often than they express themselves actively. Furthermore, transnational references seem to concentrate on a few actors like the UN, the EU, China and the USA.Thirdly, we found country and media type-related differences regarding the extent, structural patterns and reach of transnationalization. Media type differences seem to correspond with the findings research about European public sphere yielded: News coverage of quality papers is more transnationalized than regional and especially tabloid papers.  相似文献

Survey data for Canada indicates that youths have a stronger preference than adults for unionization. We show that most of that difference reflects the stronger desire of youths to have unions deal with workplace issues rather than a greater exposure of youths to these issues. In particular, youth preferences for unionization are influenced to a greater degree than for adults by social capital (e.g, familial union status and peer–group attitudes). The possible role of progressive HRM practices and legislative protection in substituting for unionization is also highlighted. Finally, implications of the findings for the future of unionization and organizing youth are discussed.  相似文献

This paper analyzes the dynamic relationship between tobacco and the rest of the economy in the colonial Chesapeake to test the staple theory version of the export-led growth hypothesis. The paper adopts a multivariate time-series approach which accommodates the presence of cointegration and contemporaneous correlations among innovations. The empirical evidence strongly supports the staple theory. British demand for tobacco is statistically exogenous and found to induce cyclical fluctuations in the colonial price of tobacco as well as temporary over- or underproduction, as measured by a long-term cointegration relationship between the British demand for tobacco and the colonial price of land.  相似文献
