The paper aims to identify those factors that cause changes in the speed and strength of the international transmission of output shocks from the USA to specified European economies. These factors are identified through the use of generalized impulse response functions conditioned on histories defined by an abrupt transition VAR. The chosen transition variables comprise changes in exchange rates, financial prices, international capital flows, trade links and monetary policy instruments. Besides the identification of asymmetric responses, the proposed model is useful in analyzing the strong effect of the recent US recession on the European economies and changes in business cycle synchronization over time.

This paper is concerned with the search for locally optimal designs when the observations of the response variable arise from
a weighted distribution in the exponential family. Locally optimal designs are derived for regression models in which the
response follows a weighted version of Normal, Gamma, Inverse Gaussian, Poisson or Binomial distributions. Some conditions
are given under which the optimal designs for the weighted and original (non-weighted) distributions are the same. An efficiency
study is performed to find out the behavior of the D-optimal designs for the original distribution when they are used to estimate
models with weighted distributions. 相似文献

This study draws on the Resource‐Based View to analyze the effects of distinctive competences in tourism firms and location in a tourism district on competitive position, and explores the moderating effects of the tourism destination. Multiple linear regression was used to test the research hypotheses on a sample of 1019 Spanish tourism firms. Results reveal that financial resources and dynamic and production capabilities favor a better competitive position for tourism firms in general; however, coordination and marketing capabilities are key factors for firms embedded in a tourism district, while dynamic capabilities have a negative effect in this case.

This paper analyzes jointly optimal fiscal and monetary policies in a small open economy with capital and sticky prices. We allow for trade in consumption goods under perfect international risk-sharing. We consider balanced-budget fiscal policies where authorities use distortionary taxes on labor and capital together with monetary policy using the nominal interest rate. First, as long as a symmetric equilibrium is considered, the steady state in an open economy is isomorphic to that of a closed economy. Second, sticky prices’ allocations are almost indistinguishable from flexible prices allocations both in open and closed economies. Third, the open economy dimension delivers results that are qualitatively similar to those of a closed economy but with significant quantitative changes. Tax rates are both more volatile and more persistent to undo the distortions implied by terms of trade fluctuations. 相似文献

This paper investigates a fundamental issue in the current research on strategic groups: the existence or non‐existence of the so‐called ‘stable strategic time periods’ (SSTPs). Our study provides new evidence by adding new methodological and theoretical insights. The research setting is the Spanish banking industry over a 15‐year period, 1983–1997. Unlike all prior longitudinal research that found SSTPs, the multi‐method procedure that we used in this study (i.e. equality of variance and covariance matrix and mean vector of strategic variables and a subsequent grouping analysis performed through the MCLUST) has led us to reject the existence of SSTPs in the industry under study. Based on these original findings, we conclude by suggesting a proposition which should be corroborated in future empirical studies on strategic groups. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Data availability is one of the traditional obstacles confronting researchers carrying out international empirical studies in accounting. In recent years several databases have claimed to offer comprehensive coverage of accounting and financial data of firms worldwide. We analyse whether the choice of database has an effect on the results of empirical studies. We find that the results of a simple empirical adaptation of the Ohlson (1995 ) model for fourteen member states of the European Union change significantly depending on the database chosen (Datastream, Global Vantage, Company Analysis, Worldscope, Thomson Financial, Financials and BvD Osiris). These differences are mainly attributable to differences in the samples across databases. When we match observations across all databases the differences persist but are much less pronounced. Our main conclusion is that database choice matters, as it leads to different results when the same research design is used. 相似文献

The concept of the natural rate of unemployment is central to policy making because it indicates the capability of an economy
to increase the growth of employment without increasing inflation. Since it is a nonobservable variable, an empirical counterpart
must be estimated. The methodology used is based on a system of simultaneous equations that combines nominal developments
(wage and price data) with the structural and institutional features (real data) of the economy. Hence, estimates of the natural
rate and potential output which are consistent between themselves are obtained. They are both robust in terms of their relationship
to actual wage and price inflation and comprehensive in terms of their underlying structural determinants. 相似文献

This work complements some of the results appearing in the article “Publishing Performance in Economics: Spanish Rankings” by Dolado et al. (Span Econ Rev 5: 80–103, 2003) Specifically we focus on the robustness of the results regardless of the time span considered, the effect of the choice of a particular database on the final results, and the effects on changes in the unit of institutional measure (departments vs. institutions as a whole). Differences are significant when we expand the time period considered. There are also significant but small differences if we combine datasets to derive the rankings. Finally, department rankings offer a more precise picture of the situation of the Spanish academics, although results do not differ substantially from those obtained when overall institutions are considered. 相似文献

Using the EU‐SILC database, we estimate and compare the Inequality of Opportunity (IO) of 23 European countries in 2005. IO is estimated as the between‐type (ex‐ante) inequality component following the parametric procedure of Ferreira and Gignoux (2011 ), which allows for the inclusion of the large set of circumstances in the database. We also measure the degree of correlation between IO estimates and a set of past and contemporaneous economic factors related to the degree of development, labor market performance, investment in human capital, and social protection spending. 相似文献

This study aimed to describe the distribution of injury mechanisms and to assess the impact of those mechanisms on the morbidity and mortality of trauma. All patients admitted to Puerto Rico Trauma Hospital (2002–2011) for road-traffic collisions (RTCs, 5,371), gunshot wounds (GSWs, 2,946), falls (2,319), pedestrian accidents (1,652), and stab wounds (SWs, 1,073) were selected. Gunshot victims were 1.19 (95%CI: 1.07–1.33) times as likely as road-traffic victims to have an ISS ≥25. Pedestrians were 1.76 (95%CI: 1.49–2.09) times more likely to have a GCS ≤8 than road-traffic victims were. The risk of dying was 2.64 (95%CI: 2.20–3.16) times higher for gunshot victims and 1.51 (95%CI: 1.23–1.86) times higher for pedestrians compared to patients who had had RTCs. Gunshot victims and pedestrians had the worst clinical outcomes. Accordingly, these patients should receive the most aggressive clinical management. Furthermore, it is imperative to develop public health campaigns on trauma prevention. 相似文献
