This study measured the impact of special agricultural safeguards (SSG) on dairy products imports by the US and Japan. It was observed that dairy products have been the most affected by this protectionist measures, and that these countries are relevant importers that impose SSG. The tariff lines subject to SSG were selected, and the period of analysis was from 1995 to 2015. The results showed that the impact of SSG applied by the US was much higher than for Japan. The overall estimated value of imports that did not happen due to the application of SSGs was approximately USD 2 billion. Specifically for the Brazilian economy, the condensed milk not exported to the US due to SSG applied cost the country BRL 345 million in GDP value and almost 4.5 thousand jobs. These results might be underestimating these effects, since the SSG tariff was not subject to calculation in several years. 相似文献

Dispersion in wage premiums and firm performance 总被引:2,自引:0,他引:2
Using matched employer–employee panel data, we estimate measures of pay dispersion per firm-year that take into account both firm and worker unobserved heterogeneity. Unlike research that controls only for differences in observables, we find that within-firm pay inequality is significantly associated to lower firm performance. 相似文献

We develop a model of innovation and learning that incorporates explicitly the need for a firm to conduct its own research and development (R&D) in order to realize involuntary spillovers from other firms’ R&D activity and the development of absorptive capacity of research firms over time. The conclusions of the model follow directly from the functional forms that are used to describe the generation and absorption of technological knowledge. The first proposition formally characterizes the steady-state rate of growth of technology for the model. The analysis also shows how some of the key features of two distinct, pure modes of organization of the production of new knowledge, the R&D model and the new localized knowledge model, are implied by our model by simply drastically changing the relative magnitude of two exogenous parameters: the ease of learning and the pace of knowledge advance. The second proposition formally characterizes the connections implied by the model between involuntary spillovers and absorptive capacity. Analysis of the long-term interactions between involuntary spillovers of knowledge and absorptive capacity provides the essential insights into an understanding of the elements of a self-sustained process of endogenous growth. The third and last formal proposition of this paper accommodates firm-level arguments and the crucial role of a firm's absorptive capacity in taking advantage of its location in clusters, as implied by the theoretical model. 相似文献

The paper develops a formal model of external knowledge and identifies the role of knowledge multipliers. Social interactions and knowledge multipliers play a crucial role in determining the rate of technological change. The analytical identification of the knowledge multiplier expression constitutes a key step in the appreciation of the crucial role of knowledge interactions. First, social considerations endogenously change the knowledge production function of each firm. The knowledge multiplier is the specific mechanism by means of which external knowledge contributes to enhance the innovative capacity of each firm. The production function of knowledge shows that the larger the knowledge multiplier is the stronger are the cumulative positive effects of external knowledge on the generation of new knowledge. Second, social considerations explain the long-run dynamics of innovation. Social reinforcement and the knowledge multiplier determine the rise or fall in the rate of accumulation of technological knowledge. 相似文献

The provision of identities online continues to be a fiercely debated topic in policy circles, with proposals emerging for public sector organizations to leverage pre-existing social networking services for their own identity management purposes. Within the broader context of private sector organizations springing up as identity providers, this article explores — from a socio-legal perspective — the merits and drawbacks of using social networking services for government eID in Europe. It then reviews the present and future European policy environment concerning official use of social networking credentials. We focus specifically on legislative measures currently being proposed in the EU to facilitate the Identification, Authentication and Signature policy, within the scope of the ongoing Electronic Signatures Directive revision process and the launch of the proposed Electronic Trust Services Regulation. 相似文献

We analyze competitive economies with risky investments. Unlike the classic Arrow–Debreu framing, firms and agents cannot contract upon the exogenous states underlying production risks. They can trade equities and any security written on the endogenous aggregate output. This financial structure is rich enough to promote efficient risk sharing among consumers. However, markets are incomplete from the production perspective, and the absence of prices for each primitive state of nature raises the question about the objective of firms. We show that output‐contingent asset prices convey sufficient information to compute the competitive shareholder value that leads to efficient investment by firms. 相似文献

Internally displaced people (IDPs) constitute a serious economic, social and cultural problem for many countries, including countries in transition. Despite the importance of the problem, there are only a handful of previous studies investigating the issue of labour market outcomes for IDPs. Moreover, the impact of protracted displacement has not been addressed in academic work at all. We aim to fill this gap in the literature using 13 years (2004–2016) of Integrated Household Surveys from Georgia, which has experienced a large flow of internal migrants from the early 1990s until now. Our analyses indicate that the labour market outcomes for IDPs are much worse than those for local residents. Specifically, IDPs are 3.9–11.2 percentage points less likely to be in the labour force, depending on the period and duration of IDP status. IDPs are also up to 11.6 percentage points more likely to be unemployed, even after 20 years of forced displacement. Finally, IDPs residing in a locality for more than five years receive persistently lower wages than local residents with similar characteristics, with the gap widening over time, reaching some 11% in the last period under analysis. 相似文献

The objective of this study is to identify the weighted importance of intrinsic and extrinsic attributes. Intrinsic attributes are defined as the specific features of products. Extrinsic attributes refer to other characteristics that are also important for price composition, such as brand, store layout and services, and purchasing experiences. In a survey with 1,923 collected responses, it was possible to identify and quantify intrinsic and extrinsic influencing factors beyond price strategy in the Brazilian fashion market for blue jeans. The statistical analysis was based on the hedonic price method. The idea of expressing the price based on a series of intrinsic and extrinsic variables avoids the problem of using the regression technique. In this research, multiple linear regression and quantile regression were applied. The results show that extrinsic attributes have greater influence than intrinsic features on explaining the final market prices using log-linear and quantile regression statistical methods. 相似文献

Stress and its associated health issues are a serious concern, because they not only affect employees but also organizations through related costs. The common perception is that being at the top of a hierarchy is associated with higher levels of stress because of the increased responsibilities, challenges, and demands. The present study examines this perception by applying a fuzzy-set qualitative comparative analysis. The study investigates how the top position, authority, number of subordinates, workload, and a sense of control, alone or in combination, lead to stress or its absence. The results show that there are several recipes for stress and that being (or not being) in the top position is neither a sufficient nor a necessary condition for stress (or absence of stress). One of the recipes, however, indicates that being in the top position might be conducive to stress. This finding shows that the position an individual has in the hierarchy does not determine stress. The present study also shows that the absence of a sense of control is almost always a necessary condition for predicting stress and is present in all recipes for the absence of stress. The results can inform managers about the conditions that cause stress and enable managers to think about solutions that can lead to good mental health in their organizations. 相似文献
