This paper tests the pro‐competitive effect of imports on product and labour markets for Spanish manufacturing firms in the period 1990–2005. In doing so, it takes into account the type of imported products: final versus intermediate. Markups are estimated following the procedure suggested by Roeger and including an efficient bargaining model. The observed heterogeneity among firms is parametised to consider additional product standardisation and market concentration. The results support the imports as market discipline hypothesis for importers of final goods, while firms that offshore intermediate inputs show similar markups to nonimporters. Additionally, the union bargaining power is smaller for importers and the more homogeneous is the type of goods elaborated by firms. 相似文献

A large body of literature argues that the characteristics of exports matter for economic growth and development because some goods trigger positive externalities or are subject to increasing returns. Thus, for policy purposes, it is important to know whether a country’s export basket enjoys these productive opportunities. They have been associated with technological content of exports. However, measuring them is not easy. Previous methodologies to account for exports’ technological content used either R&;D data or trade data. The former is used to account for knowledge-intensive activities during the production phase and the latter to identify levels of ‘sophistication’ of exports based on exporting countries’ characteristics. Building on these contributions, this paper combines industry-based and product-based indicators to circumvent some of the shortcomings of the received literature, including the product-industry controversy (i.e. are the actual activities during the production process or the product characteristics what better accounts exports’ technological content?). We use data from Uruguay on direct and indirect R&;D spending from public and private sources and also trade data to build the sophistication index corrected by quality. We contrast our findings with existing methodologies to highlight our contribution. 相似文献

In this article, the authors discuss the use of Federal Reserve Economic Data (FRED) statistics to teach the concept of price elasticity of demand in an introduction to economics course. By using real data in its computation, they argue that instructors can create a value-adding context for illustrating and applying a foundational concept in economics. Additionally, this pedagogical strategy contributes to developing an expected proficiency for economics majors related to “interpreting and manipulating data” (Hansen 2009, 2012). The authors provide step-by-step instructions on how to use FRED to compute the price elasticity of demand for motor vehicle fuels and gasoline as well as examples of in-class discussion questions and take-home assignments related to this instructional technique. 相似文献

Remittances play a large and important role in certain economies, where they became a significant share of GDP. Official government records of these flows have been systematically improved since governments realized their importance, but a significant percentage of remittances remain unrecorded. This, together with the shadow economy, may pose a problem for monetary policy. This article uses a limited participation model to examine the differential effect that higher shares of remittances can have on monetary policy and describes the impact of remittances on a small open economy under partial sterilization. It demonstrates how a typical monetary shock will lead to a more pronounced liquidity effect when remittances become a higher proportion of GDP. It also shows that a positive remittance shock improves consumption and lowers interest rates, but as it also reduces work effort it momentarily lowers output. Such dynamics are exacerbated as the degree of partial sterilization is accentuated. 相似文献

This study analyses Italian hedge funds performance and persistence. The peculiarity of the Italian hedge fund industry is that 95% of the hedge funds are funds of hedge funds (FoHF), whereas only 5% of them employ other investment styles. Using monthly data on FoHF provided by MondoHedge, we examine the impact of both market variables and funds’ own characteristics on funds performance using panel data. We find that the European, the Japanese and the emerging markets equity markets, and the commodity market have a positive impact on Italian FoHF performances, while the US Bond Market negatively affects them. Moreover, we find performance fees and notice days to have a negative impact on funds performances. Finally, we test the presence of performance persistence. Employing two different nonparametric methods, we find that funds performances are persistent on a monthly and quarterly basis, while the regression-based parametric method provides evidence of persistence only on a monthly basis. 相似文献

There is substantial research and policy interest in the relationship between firms and the natural environment, including how this relationship is influenced by regulators, international pressures, rival firms and stakeholder demands. With some exceptions, the ‘softer’ dimensions of environmental aspect management – how attitudes, beliefs and perceptions and the human factors drive corporate behaviour – have been understudied. The work that exists tends to be informal, and allows little scope for the statistical validation that is required for robust inference. This paper examines whether corporate values towards the environment affect a firm's environmental performance. It uses survey methods as well as content and discourse analyses of interview text and corporate reports and web sites to explore the links between managerial ‘mindsets’ and the environmental performance of the firms of which they are a part. Though the application is Argentina, the lessons learned can be generalized to other developing and industrialized countries. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment. 相似文献

In this contribution, we present a virtual voyage through 3D structures generated by chaotic mixing of magmas and numerical simulations with the aim to highlight the power of 3D representations in the understanding of this geological phenomenon. In particular, samples of mixed juveniles from Salina island (Southern Italy) are reconstructed in 3D by serial lapping and digital montage and numerical simulations are performed by using a 3D chaotic dynamical system. Natural and simulated magma mixing structures are visualized by using several multimedia tools including animations and “virtual reality” models. It is shown that magma interaction processes can generate large spatial and temporal compositional heterogeneities in magmatic systems. The same topological structures are observed in both 3D reconstructed rock samples and chaotic numerical simulations, indicating that the mixing of magmas is governed by chaotic dynamics. The use of 3D multimedia models gives the opportunity to penetrate into magma mixing structures and to understand their significance in the context of magma dynamics. Such an approach is very powerful since multimedia tools can strongly capture the attention of the reader bringing him/her into an interactive and memorable geological experience. 相似文献
