Using a sample of 97 countries spanning the period 1980–2008, we estimate that banking crises have, on average, a large negative impact on unemployment. This effect, however, largely depends on the flexibility of labor market institutions: while in countries with more flexible labor markets the impact of banking crises is sharper but short-lived, in countries with more rigid labor markets the effect is initially more subdued but highly persistent. These effects are even larger for youth unemployment in the short term, and long-term unemployment in the medium term. Conversely, large upfront, or gradual but significant, comprehensive market reforms have a positive impact on unemployment, albeit only in the medium term. 相似文献

Managing innovation and particularly searching for new ideas in a steady state environment is really different than in discontinuous conditions where traditional practices and routines may prove ineffective. This paper reviews and empirically explores the field of search strategies and practices for discontinuous innovation and, for the first time, tests the validity of a ‘discontinuous innovation (DI) search capacity’ construct. Based on a comprehensive literature review on the innovation search stage and on the evidence of more than 80 case studies reported by the Discontinuous Innovation Laboratory, a questionnaire was developed and submitted to a 500 high-tech firm sample. Four DI search dimensions were identified, each consisting of a bundle of interrelated yet distinct practices. We empirically tested the DI search capacity and measured it as a second-order construct by using the structural equation modelling. 相似文献

The aim of the article is to analyse the relationship between long-run growth and business cycle volatility. In particular, the main purpose of this article is to identify which source of volatility is most detrimental to growth. Using cross-country data from 1970 to 2000, and several indicators of volatility (such as inflation, exchange rate, government expenditure, output and investment volatility) this article shows that although, all these measures of volatility are remarkably harmful for growth, business cycle investment volatility is the main source that hampers long-run growth. This relation is robust to different measures of business cycle, and to different sub-samples of countries. 相似文献

We develop a discrete-time stochastic volatility option pricing model exploiting the information contained in the Realized Volatility (RV), which is used as a proxy of the unobservable log-return volatility. We model the RV dynamics by a simple and effective long-memory process, whose parameters can be easily estimated using historical data. Assuming an exponentially affine stochastic discount factor, we obtain a fully analytic change of measure. An empirical analysis of Standard and Poor's 500 index options illustrates that our model outperforms competing time-varying and stochastic volatility option pricing models. 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

This paper focuses on the expansion strategies in foreign markets of a sample of Italian firms during the period 1987-93. The data reveal strong dynamics in entry and exit strategies and an overall increase in Italian firms' foreign manufacturing activities. Firms seem to be restructuring and reorganising their range of activities in view of the new competitive scenario promoted by the completion of the Single European Market. A logit model investigating the determinants of entry in foreign markets is tested at the firm level. The results suggest that firms' specific resources, target industry and foreign country characteristics are important explanatory variables. Some new insights concerning the export substitution effect, the presence of technological sourcing and the multinational/ diversification dichotomy are also discussed. 相似文献

This paper quantifies the relative contribution of domestic, regional and international factors to the fluctuation of domestic output in six key Latin American (LA) countries: Argentina, Bolivia, Brazil, Chile, Mexico and Peru. Using quarterly data over the period 1980:1-2003:4, a multi-variate, multi-country time series model was estimated to study the economic interdependence among LA countries and, in addition, between each of them and the three world largest industrial economies: the US, the Euro Area and Japan. Falsifying a common suspicion, it is shown that the proportion of LA countries' domestic output variability explained by industrial countries' factors is modest. By contrast, domestic and regional factors account for the main share of output variability at all simulation horizons. The implications for the choice of the exchange rate regime are also discussed. 相似文献

This paper reports a longitudinal field study on the effects of positive media coverage on the reconstruction of organizational identity. The study highlights how intense positive coverage – to the point of turning an organization into a ‘celebrity’– influences both the way members understand their organization (sensemaking effect) and the gratification they derive from its positive representation (self‐enhancement effect). Our findings suggest that positive media representations foster members' alignment around an emergent new understanding of what their organization is. Over time, however, celebrity may ‘captivate’ members' organizational identity beliefs and understandings, and impede further identity work as media persist in the replication of representations that differ from members' experienced reality, but are too appealing to them to be publicly contradicted. 相似文献

This paper adopts a new approach that accounts for breaks to the parameters of return prediction models both in the historical estimation period and at future points. Empirically, we find evidence of multiple breaks in return prediction models based on the dividend yield or a short interest rate. Our analysis suggests that model instability is a very important source of investment risk for buy-and-hold investors with long horizons and that breaks can lead to a negative slope in the relationship between the investment horizon and the proportion of wealth that investors allocate to stocks. Once past and future breaks are considered, an investor with medium risk aversion reduces the allocation to stocks from close to 100% at short horizons to 10% at the five-year horizon. Welfare losses from ignoring breaks can amount to several hundred basis points per year for investors with long horizons. 相似文献

In this paper we argue that the learning of safety in a constellation of communities of practice is mediated by comparison among the perspectives of the world embraced by the co‐participants in the production of this practice. Our discussion is based on two empirical research projects in which we investigated the accounts of the causes of accidents provided by the members of three different communities of practice (engineers, site foremen and main contractors), in a medium sized building firm. In the paper we suggest that comparison among perspectives is made possible by a discursive practice targeted on the alignment of elements both mental and material, within mutually accountable discursive positions. These alignments are provisional and unstable, they produce tensions, discontinuities and incoherence (cacophony) just as much as they produce order and negotiated meanings (consonance). 相似文献
