In Italy the main difference between apprentices and other types of temporary workers is that apprentices must receive firm-provided training. The firm incentive in hiring apprentices consists in paying lower wages and labour taxes. Using an Italian administrative dataset containing information on the jobs started between January 2009 and June 2012, we estimate the effect of apprenticeship on the hazard function to a permanent job. Identification is based on a regression discontinuity design. We find that, for 29-year-old workers, apprenticeships are “long entrance halls” towards permanent contracts, especially within the firm where the apprenticeship is performed.

A vast body of literature suggests that the European Alpine Region is extremely sensitive to climate change. Winter tourism is closely related to climate variations, especially in mountain regions where resorts are heavily dependent on snow. This paper explores how to effectively integrate a climate change adaptation perspective with local discourses about sustainability and tourism, an increasing priority for policy-makers in the region and elsewhere. It reports on the development and application of a participatory decision support process for the analysis of adaptation strategies for local development of an Alpine tourism destination, Auronzo di Cadore (Dolomites, Italy). This experience significantly contributed to the idea that an efficient combination of modelling capabilities, decision support tools, and participatory processes can substantially improve decision-making for sustainability. The authors show that, in this case study, such a combination of methods and tools allowed for managing the involvement of local actors, stimulating local debates on climate change adaptation and possible consequences on winter tourism, encouraging creativity and smoothing potential conflicts, and easing the integration of the qualitative knowledge and the preferences of the involved actors with quantitative information. This contributed to an integrated sustainability assessment of alternative strategies for sustainable tourism planning.  相似文献

With the changing way people live, communicate, and work, enterprises are striving to shift their existing business model into a “self‐tuning” one. Enterprises are becoming more agile, adaptive, and ambidextrous in order to boost innovation in the current digital transformation era. Nowadays, “digital innovation” is closely associated with Industry 4.0 enablers and smart enterprises. Prior research has shown that while multinational enterprises—across many sectors—have already embraced the aforementioned advancements, their adoption by small and‐medium‐sized enterprises (SMEs) has so far taken place mainly in the manufacturing sector. Thus, based on a sample of 280 self‐tuned smart manufacturing SMEs and having utilized the structural equation modeling (SEM), this study was aimed to investigate how digital innovation is influenced by the three pillars of self‐tuning models—agility, adaptation, and ambidexterity. Our paper has focussed on the digital systems in which SMEs, spurred by networking and open innovation solutions, operate and innovate in response to external triggers, displaying a balance between exploration and exploitation, and a strong agile capacity.  相似文献

Information used to manage the business and support the decision‐making of stakeholders is being subject to an evolution. In this context, traditional financial reporting is considered not sufficient anymore. This has translated into a sharp increase in the number of firms that have begun to adopt emerging reporting practices. This study aims to examine the influence that both firm‐ and country‐specific characteristics have on the voluntary uptaking of integrated reporting internationally. In order to do so, it analyses a sample of 71 international listed companies that have adopted this reporting form in 2016. The results show that firms are more likely to implement integrated reporting if they are located in countries with a higher level of corruption perception and a better risk rating and that are considered as relatively more collectivist and feminist and with a long‐term orientation. Legal system has resulted to be not significant. As for firms' characteristics, large size, profitability, market‐to‐book ratio, and the size of the board are found to be significant variables. Moreover, the results indicate that the adoption of integrated reporting is not influenced by a higher level of leverage, firm efficiency and board diversity and independence.  相似文献

On the measurement of intra-industry trade: Some further thoughts   总被引:1,自引:1,他引:1  
Zusammenfassung Zur Messung des intra-industriellen Handels. Einige weitere Gedanken. — Der Autor untersucht, was für und was gegen das Argument des Korrekturbedarfs bei der Messung des intra-industriellen Handels (IIH) spricht, und kommt zu dem Ergebnis, da\ eine Korrektur sowohl aus theoretischen als auch aus empirischen Gründen abzulehnen ist. Der unkorrigierte Index von Grubel und Lloyd hat sich als der beste der gegenw?rtig verfügbaren Indizes erwiesen, wenn er auch ziemlich stark auf das Ausma\ der Datendisaggregierung reagiert. Empirische Studien scheinen darauf hinzudeuten, da\ die Ebene der 4- bis 5-stelligen SITC am besten geeignet ist, um den IIH zu messen. Selbst an Hand dieser stark disaggregierten Daten ist der auf bilateraler Basis berechnete IIH sehr beachtlich, besonders wenn er mit dem hier vorgeschlagenen neuen Index gemessen wird. Dieser Index wird aus theoretischen überlegungen abgeleitet und ist nicht mit dem überlappen des Handels verknüpft.
Résumé Des mésures du commerce intra-branche: Quelques réflexions supplémentaires. — Dans cette étude l’auteur examine les points positifs et négatifs de l’argument d'une ?nécessité de la correction? en mesurant le commerce intra-branche. Il conclue que la nécessité devrait être rejetée à cause de la théorie et l’évidence empirique. On trouve que l’indicateur de Grubel et de Lloyd est le meilleur de ceux qui sont au moment disponibles. Il réagit néanmoins de mesure considérable au niveau de la disagrégation des données. L’évidence empirique semble montrer que le niveau de 4 ou 5 chiffres CTCI est le plus adéquat pour mesurer le commerce intra-branche. Même avec ces données très hautement disagrégées le commerce intra-branche est tout considérable, particulièrement si mesuré par le nouvel indicateur du commerce intra-branche qui est proposé ici. Cet indicateur est dérivé des considérations théoriques et n'est pas lié aux échanges croisés.

Resurnen Sobre la medición del comercio intrasectorial: algunas ideas más. — En este trabajo se examinan las ventajas y desventajas del argumente de la necesidad de corrección al medir el comercio intrasectorial y se concluye que deberia ser rechazado en base a razones teóricas y empiricas. El indice no corregido de Grubel y Lloyd es el mejor de los indices existentes; sin embargo, es sensible al nivel de desagregacón. La evidencia empírica parece indicar que el nivel de 4 a S digitos de la SITC es el nivel más apropiado para medir el comercio intrasectorial. Incluso medido a este nivel altamente desagregado, el comercio intrasectorial computado bilateralmente résulta bastante importante, especialmente si es medido con el nuevo indice propuesto aqui. Este indice es derivado de consideraciones teóricas y no esta ligado a la superposition del comertio.

The effect of different supplementary feeding rates for grazing cattle on high-altitude pastures dynamics was evaluated. A field experiment was carried out during three years in a subalpine pasture area of the Eastern Alps. The investigated pasture area was 40?ha, located between 1820 and 2230?m?a.s.l. Two paddocks were chosen in the experiment and two herds of 12 cattle each were kept in the two enclosures for 5 weeks. For the first herd (HS), the supplementary feeding rate was 4.8?kg?OM?head?1 per day, while for the second herd (LS), the rate was 1.6?kg?OM?head?1 per day. The amount of herbage consumed by each cattle was determined using the n-alkane technique. To monitor the pasture vegetation dynamics, eight metal exclusion cages were placed in each paddock to determine herbage growth, utilization rates, vegetation composition and animal grazing selectivity. Grazing behaviour of dairy cattle, in terms of herbage intake and species selection was affected by the different feeding rates. Cattle grazing Paddock HS consumed 1.9?kg?OM?day?1 of herbage less than Paddock LS. In the LS paddock, cattle grazed higher phytomass rates. When the animals were fed by higher concentrate rates, a more selective grazing seemed to significantly increase the pasture necromass component. The lower grazing selectivity favoured the development of species as Nardus stricta and Deschampsia caespitosa, which are well known for their low palatability. Distinct vegetation dynamic patterns were observed, with a reduction of hair grass and an increase of legumes in the Paddock LS.  相似文献

Purely technological factors can be a fundamental force behind the emergence of asset price bubbles in developed economies. We analyze an economy in which the production technology utilizes both physical and intangible capital, where the latter cannot be used as collateral for borrowing. Technological change, in the form of increased importance of intangible capital in production, sharpens the borrowing constraints of entrepreneurs, leading to a scarcity of high-yield assets relative to low-yield ones. This can create the conditions for asset bubbles. Additionally, due to the financial frictions, standard dynamic efficiency tests are not valid, and bubbles are not Pareto improving.  相似文献

In a group of companies corporate income taxation is levied on basic earnings and then on dividends paid to holding companies. The entity of this taxation depends on the tax regime, so that income may be taxed twice, first in the hands of the subsidiaries, then in the next years in the hands of holding companies. Therefore, consolidated profits may not be wholly paid to shareholders (who are the ultimate owners) and deferred taxes have to be computed in order to determine the true profitability of a group of companies. Using input–output theory, we developed a framework to estimate deferred taxation on dividends in business groups. Such relationships can be particularly useful when cross‐shareholdings exist to determine deferred liabilities under several accounting standards. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献
