A large literature studies the impact of increased import competition on workers' outcomes, however, relatively few studies examine which policies can aid workers displaced by trade. In this article, we evaluate the impact of an industrial job training program in Brazil on workers displaced from manufacturing sectors. We find that industrial training increases the probability of re-entry into the formal labor market 1 year after displacement by about 17 percentage points and is even more effective for workers displaced from sectors exposed to high import competition. This effect is mainly associated with workers switching sectors and occupations after training. 相似文献

Shadow economy and unemployment rate in USA: is there a structural relationship? An empirical analysis 总被引:1,自引:0,他引:1
This article aims to estimate the size of the US shadow economy (SE) using a structural equation approach and to evaluate if a structural relationship exists between the SE and the unemployment rate (UR) in the United States. The size of the SE is estimated to be decreasing over the last two decades. We corroborate the existence of a structural relationship between the SE and the UR by using a simple theoretical model. Furthermore, we extend the Okun's law to estimate the structural relationship between growth rate of official GDP, SE and UR. Our results indicate a significant positive relationship between the SE and the UR. 相似文献

WHEN SHAREHOLDERS CHOOSE NOT TO MAXIMIZE VALUE: THE UNION BANK OF SWITZERLAND'S 1994 PROXY FIGHT 总被引:1,自引:0,他引:1
This paper examines the fight over a share reunification plan that pitted Swiss financier Martin Ebner against Union Bank of Switzerland (UBS), once the largest Swiss bank and a global leader in asset management. In the U.S. corporate governance debate, large shareholders are often held up as a possible solution to corporate governance problems. But this examination of the UBS proxy fight shows why some large shareholders can themselves be a source of governance problems. The share reunification plan was designed to combine the firm's two classes of stock: registered (voting) shares and bearer (non-voting) shares. As its motive for the plan, the UBS board cited a desire both to increase liquidity and to prevent a control change. The majority of the holders of the company's registered stock—many of whom had other financial ties to the bank—ended up voting for a proposal that caused them to lose 11% of the value of their shares during the three trading days following its announcement, and eventually almost twice as much. Moreover, even the holders of the bearer stock hurt themselves by approving the reunification plan. Although the plan clearly transferred value from the registered to the bearer shares, the redistribution benefits from the plan for the bearer shareholders were not sufficient to offset their losses from the reduced probability of a control change. Although it did not succeed in accomplishing its immediate goal, the UBS proxy fight is today recognized as a watershed event in Swiss corporate governance. Until recently, Switzerland's economy has been dominated by cartels, with closely overlapping boards of directors. Hostile takeovers were essentially unheard of, and criticism of management by shareholders was highly unusual. Ebner's activities have had the effect of stimulating public debate about shareholders' rights and shareholder activism. In so doing, they have made it more acceptable for shareholders to criticize management and established shareholder value as a “politically correct” goal for Swiss corporations. 相似文献

Managing innovation in turbulent environments (e.g., in environments with extreme uncertainty and complexity in market needs and technological opportunities) is a major challenge. A recent stream of studies in the management literature has suggested that when facing turbulent environments, firms should deploy more flexible development processes. This paper approaches this issue by looking at the Italian mobile telecommunications (TLC) industry. Nine in‐depth case studies were conducted in five different companies. Data analysis showed some important results. First of all environmental turbulence should be considered to be project specific rather than company or industry specific. Moreover, it can come from both shift in the market needs and in the technology. Nevertheless, it seems clear that having rapid changes is not enough to have environmental turbulence. If rapid changes can be somehow foreseen, there is no turbulence at all. Hence, when approaching projects in potentially turbulent environments, managers should assess both rapidity and unpredictability of the environment. Finally, looking at the in‐depth cases, the paper points out what of the main practices to increase flexibility that are described in literature are actually adopted by companies. In case of turbulence (both in the market and/or in the technology) companies delay concept freezing point. Moreover, in the case of technological turbulence, they also leverage on rapid project iterations, whereas in case of market turbulence they more likely adopt early experiments involving customers, formal and cross‐functional project teams, and flat organizational structures. 相似文献

We investigate migrant construction workers’ experiences in the Former Soviet Union, examining their attitudes to other ethno-national groups, unions and collective action. Industrial relations and migration studies view migrant workers’ hypermobility and diversity, under conditions of low union coverage and rising nationalism, as potentially obstructing consciousness-raising and mobilizing. Workers in our study faced union indifference, ethno-national segregation and discrimination. However, managerial abuses, informality and contestation from below led to spontaneous mobilization. Lack of institutional channels to solve these disputes drove workers’ further mobility. Complex mobility trajectories and collective action translated into increased awareness of collective interests and rejection of nationalist ideologies. The outcome is ‘multinational workers’ potentially resistant to nation-state politics and capital's logics but also aware of the value and usefulness of collective solidarities. Thus, previous arguments solely associating exit with individualistic attitudes, and post-socialist legacies with workers’ quiescence present only partial pictures. 相似文献

The research presented here aims to plot density diagrams per road crash risk type to identify all possible scenarios where driving is less than safe. The starting point was the prediction of injury crash rate on horizontal homogeneous segments of two-lane rural roads for three main injurious crash types (head-on/side collisions, rear-end crashes, and single-vehicle run-off-road crashes) as observed on the network. A careful analysis of the database shows that a wide variety of factors appear to be influenced or associated with the crash dynamic, as follows: the road scenario (combination of infrastructure and environmental conditions found at the site at the time of the crash), mean lane width, the horizontal curvature indicator (measurement of the curvature change rate), and mean speed. Crashes recorded from 2003 to 2010, of which 1597 were injurious, and 645 resulted only in damage to property, were analyzed on more than 3700?km of road network in Southern Italy. Generalized estimating equations with a negative binomial distribution were implemented. Risk-type density charts were plotted to thoroughly identify all possible combinations of existing explicative variables producing hazardous conditions on the road. The different shades in the diagrams represent different ranges of injurious crash rates: the white band shows low levels, while a black band shows high values. It is not possible to consider working on an explanatory variable to reduce hazardous conditions on the road network without also considering how this variation might affect the influence of the remaining explanatory variables on crash phenomena and, consequently, on the predictive model. The risk maps make it possible to keep under control in a simple and immediate approach the way each variable as a result of variations of a part or of all. 相似文献

Regional paved roads are low volume roads with a prevalence of heavy traffic. In the world, these roads concern about 80% of the total road network; however, the traffic that affects these roads is about 20%. Since regional roads are characterized by weak demand, budget for their management/maintenance is very low. This produces considerable difficulties in the choice of strategies for maintenance planning and scheduling. For this reason, the recurring topics of research in this field deal with typical roads issues and aim to develop low cost tools and methods. The study proposes a decision support system to evaluate regional paved roads operating condition in relation to the hydrogeological situation. In particular, the system allows to evaluate in a quick and easy manner, the operating conditions of the road, through low-cost tools (i.e. using low economic resources). This is very useful in the case of LVRs because administrations for these roads have a limited budget. The procedure is developed on a regional paved roads network based on more than 80 roads located in Southern Italy. Data is collected by direct surveys in the field and is integrated with cartography and information available in road agency records. From data analysis, obtained using two different techniques, an easy and quick use procedure is made. In particular, Model 1 is built through multivariate analysis and Model 2 using the artificial neural network (ANN) technique. The results show the validity of the two models in Regional paved roads operating conditions estimation in relation to hydrogeological situations of sites. Both models show good reliability. In particular, the first model (Model 1) is characterized by a high level of significance (p < 0.01) and by a coefficient of determination equal to 0.82. Comparative tests between the second model (Model 2) on which standard tests cannot be performed for obvious reasons, and the first model (Model 1). The results show that the ANN model (model 2), characterized by lower residual, simulates more accurately than the second (Model 1). 相似文献

ABSTRACTThis paper discusses the moderating effect of frugal behavior on the relationship between food package familiarity and the perceived amount of verbal information. Two experiments were conducted on food packaging to analyze two central points: (a) the relationship between food package familiarity and the perceived amount of verbal information and (b) the moderating effect of frugal behavior on this relationship. The studies demonstrate the negative influence of food package familiarity on the perceived amount of verbal information. We demonstrate that the greater (smaller) the familiarity with food packaging is, the smaller (greater) the visual attention to the verbal information will be. Second, we show that frugal behavior moderates this behavior. Our experiment shows that a greater (smaller) tendency toward frugal behavior tends to have a positive (maintain negative) effect on the relationship between food package familiarity and the perceived amount of verbal information. 相似文献

For three years in Bolivia (2002–2005) the INNOVA Project finished researching several technologies for sustainable agriculture, started by earlier DFID-funded projects. Before INNOVA started critics suggested that these technologies should be discarded in favour of a demand survey. Instead, INNOVA kept the existing technologies, but judged the demand for them with several methods (CIAL, sondeo technology fair, and others). INNOVA found that there was demand for some of the technologies, but that a survey would have missed much of the demand, which is implicit. That is, people are not initially aware of all their problems or of all the possible solutions. Over the years, farmers made more specific, sophisticated demands on the technologies, which evolved as a result. Demand and supply of farm technology are like two sides of an unfolding conversation. 相似文献

External technology acquisition has been proved to be an important strategy to enhance firms’ innovation performance. However, previous studies claim that companies acquiring technologies tend to not carry on with this strategy over time, thus limiting their attitude toward continuous technology acquisition. Moreover, the extant literature also highlights that this attitude is strongly influenced by their organizational structure. Therefore, in the present paper, we investigate the relationship between how firms organize R&D activities and continuous technology acquisition. Specifically, given the increasing globalization of technological development, we focus on the role of R&D geographic dispersion, and how its influence is moderated by firms’ technological diversification. We tested our hypotheses on longitudinal data of 303 biotechnology firms that acquired, at least, one USPTO patented technology over the period 1982–2012. Results reveal that R&D geographic dispersion is curvilinearly (inverted U-shaped) related to continuous technology acquisition, with negative returns occurring earlier in technology-diversified companies. 相似文献
