The object of this paper is to study the relationship between the border effect and the geographic concentration of production.
We explain this relationship through the home market effect and test the robustness of this explanation by using an analysis
that considers the European single market. A sectoral gravity equation is estimated with different econometric estimators;
in particular, we discuss a recently suggested estimator for log-linear CES models. Overall, our findings suggest a steady
relationship between the border effect and the concentration of production. Furthermore, the analysis of concentration through
a synthetic index provides us with valuable insights into the structure of the European industry. 相似文献

This research aims to evaluate the state of the art of Purchasing and Supply Management (PSM). This is carried out through a wide, in-depth, and structured examination of published works. More than one thousand papers (i.e., 1055) published in 20 peer-reviewed journals were collected and analyzed to provide a snapshot of PSM research, including the extent of the overall production, the background theory used, the unit of analysis, the research method, and the main topics investigated. Other literature reviews related to PSM have been conducted in the past but have focused primarily on specific topics and/or considering a narrower set of publications. Furthermore, the authors define a framework useful for analyzing the PSM literature and outline the state of the art of PSM research from a content-specific perspective, including an evaluation of the maturity of PSM research as a discipline. 相似文献

Abstract This paper introduces a selection of papers on contemporary developments in public sector management which come from a research conference held in 2004. This paper starts by introducing the New Public Management (NPM) and governance paradigms as alternative high level approaches. Such approaches are well known in the UK and are also of international interest. It then considers whether there are further possible reform paradigms not captured by these rather State centric models. The paper then briefly introduces each of the papers selected from the Conference proceedings. These papers contribute to the literature on the NPM, on the NPM versus governance debate and also generate and apply novel theoretical perspectives. 相似文献

Abstract We show that recent explanations of the consumption‐real exchange rate anomaly that rely on goods and financial market frictions are not robust to introducing just one additional international asset. When portfolios are selected optimally, international trade in two nominal bonds implies a consumption‐real exchange rate correlation that is too high compared with the data even when there are many shocks. Monetary policy specification plays a potentially important role for the degree of risk sharing provided by nominal bonds, both in the benchmark model with only tradable and non‐tradable sector supply shocks and also in the model that allows for news. 相似文献

We analyze the volatility surface vs. moneyness and time-to-expiration implied by MIBO options written on the MIB30, the most important Italian stock index. We specify and fit a number of models of the implied volatility surface and find that it has a rich and interesting structure that strongly departs from a constant volatility, Black-Scholes benchmark. This result is robust to alternative econometric approaches, including generalized least squares approaches that take into account both the panel structure of the data and the likely presence of heteroskedasticity and serial correlation in the random disturbances. Finally we show that the degree of pricing efficiency of this options market can strongly condition the results of the econometric analysis and therefore our understanding of the pricing mechanism underlying observed MIBO option prices. Applications to value-at-risk and portfolio choice calculations illustrate the importance of using arbitrage-free data only. 相似文献

While research on user innovations within communities exists mainly in offline contexts, few studies have attempted to define the profile of lead users in online (or virtual) communities, and even fewer have been conducted in the specific context of online brand communities, formed by people with a “common interest in a brand,” in its evolution and in the discourse about it. This study focuses on innovative activities within the Ducati Motor online community. The research reveals the following characteristics as crucial factors for the identification of lead users in online brand communities: willingness to collaborate, product knowledge and strategic alignment with the brand identity. Our sample consists of 2071 messages posted by 572 Ducati Motor virtual community members in a specific blog developed by Ducati Motor with the purpose of involving members in a collaborative innovation process that took nearly 14 months. Several implications for scholars and new product development managers are discussed. 相似文献

We are the first to examine the market reaction to 13 announcement dates related to IFRS 9 for over 5400 European listed firms. We find an overall positive reaction to the introduction of IFRS 9. The regulation is particularly beneficial to shareholders of firms in countries with weaker rule of law and a smaller divergence between local GAAP and IAS 39. Bootstrap simulations rule out the possibility that sampling error or data mining are driving our findings. Our main findings are also robust to confounding events and the extent of the media coverage for each event. These results suggest that investors perceive the new regulation as shareholder-wealth enhancing and support the view that stronger comparability across accounting standards of European firms is beneficial to international investors and outweighs the costs of poorer firm-specific information. 相似文献

This paper studies the determinants of the recent proliferation of Specific Trade Concerns raised at the WTO on non‐tariff trade measures (NTMs), with a focus on sanitary and phytosanitary (SPS) and technical barriers to trade (TBTs). Even though NTMs are imposed de jure to protect consumers from unhealthy products, they increase trade costs de facto. So, when tariff protection lowers, NTMs become effective barriers to trade and the exporting countries can complain at the dedicated committee at the WTO (STCs). Therefore, we study whether STCs are raised by exporting countries as a consequence of tariff reductions in importing countries, that is when non‐tariff measures become barriers to trade. Using a recent database on STCs over the period 1996–2010, we find empirical evidence that SPS and TBT concerns are raised by exporting country as a consequence of importer's tariff cut. 相似文献
