We use Bayesian time‐varying parameter structural vector autoregressions with stochastic volatility to investigate changes in reduced‐form and structural correlations between inventories and either sales growth or the real interest rate in the USA during both the inter‐war and post‐World War II periods. We identify four structural shocks by combining a single long‐run restriction to identify a permanent output shock with three sign restrictions to identify demand‐ and supply‐side transitory shocks. We show that during both the inter‐war and post‐war periods the structural correlation between inventories and real interest rate conditional on identified interest rate shocks is systematically positive; the reduced‐form correlation between the two series is positive during the post‐war period, but in line with the predictions of theory it is robustly negative during the inter‐war era; during that era the correlations between inventories and either of the two other series exhibit a remarkably strong co‐movement with output at business cycle frequencies.

The social solidarity economy is an approach to the production and consumption of goods, services and knowledge that promises to address contemporary economic, social and environmental crises more effectively than business as usual. The paper employs the concept of commons ecologies to examine the practices, relationships and interactions among actors and organisations in the social solidarity economy, as well as between them and the mainstream economy, which shape the field and its degree of autonomy in relation to capitalism, through a process defined as boundary commoning. Such process shapes both local and regional commons ecologies, as well as the participation of local and regional actors in wider networks at national, international and global levels. The paper takes a case study-based approach to identify practices, relationships and interactions of commons ecologies in relation to selected community-led initiatives in the UK, Portugal, Brazil and Senegal. Each case study illuminates different qualities of local/regional commons ecologies and their forms of engagement with wider networks. Further, the paper shows that these cases demonstrate how the social solidarity economy may facilitate delivery of the Sustainable Development Goals in a distinctive way. In each case, SSE acts as a vehicle for expressing participants' values and principles consistent with those underlying the SDGs. Local implementation of SDGs is thus an in-built feature of these commons ecologies. The participation of community-led initiatives in international and global networks offers opportunities to learn from local level experiences and successes, potentially strengthening SDG implementation more generally. 相似文献

In this paper, we analyze the labor market impacts of immigration under flexible and rigid labor market regimes. A general equilibrium framework is developed, accounting for skill heterogeneity and labor market frictions, where unemployed medium‐skilled manufacturing workers are downgraded into low‐skilled service jobs, while low‐skilled service workers might end up unemployed. The analytical analysis shows that medium‐skill immigration decreases low‐skilled unemployment under the flexible regime, indicating a complementarity effect, while the rigid regime induces a substitution effect, leading to low‐skilled unemployment. Moreover, it leads to wage polarization. In a numerical analysis, the economic effects of different migration scenarios are quantified. 相似文献

The growing reconciliation between the United States and Cuba has created a unique opportunity for U.S. business and hospitality students to observe and experience first-hand an economy in marked transition. Attempting to balance the tenets of socialism with a rapidly growing reliance on capitalism creates a rare learning environment for students. This article presents the plan for a 10-day faculty-led study abroad program to Cuba. The program is divided between the two (arguably) most important destinations in Cuba: the economic and cultural center, Havana, and the tourism powerhouse of Varadero. At each destination, students are engaged in lectures, site visits, research, and cultural experiences. 相似文献

Cross‐section regressions often examine many candidate regressors. We use multiple testing procedures (MTPs) controlling the false discovery rate (FDR) — the expected ratio of false to all rejections — so as not to erroneously select variables because many tests were performed, yielding a simple model selection procedure. Simulations comparing the MTPs with other common model selection criteria demonstrate that, for conventional tuning parameters of the selection procedures, only MTPs consistently control the FDR, but have slightly lower power. In an empirical application to growth, MTPs and PcGets/Autometrics identify similar growth determinants, which differ somewhat from those obtained by Bayesian Model Averaging. 相似文献

Most companies are under pressure to improve the environmental sustainability of their supply chains. However, there is considerable variance in companies' ability to successfully deploy environmental management projects. One important factor, according to articles in the academic and business press, is the ability of champions of sustainable supply chain management (SCM) projects within organizations to gain the commitment of colleagues (e.g., other managers from a variety of functions) to help these projects succeed. Therefore, this paper examines variables that affect a project champion's ability to gain this commitment from colleagues. In particular, building on existing research, this research employs a video‐based experimental design to examine the effect of the influence approach that the project champion employs, the values of the person the champion is trying to influence, and the organizational climate. The results suggest that organizational climate and certain individual values directly affect commitment. There are also interactions between values and influence tactics. The research adds to the field's growing knowledge on the antecedents of sustainable SCM within companies while providing valuable guidance for environmental champions and for top managers. 相似文献

The Brazilian cities as well as many of the large urban centers in the world continue to expand, increasing the demand for mobility and transport, while, at the same time, the same cities are investing in greenhouse gas (GHG) mitigation to avoid climate change. Brazil's urbanization rate increased from 26% in 1940 to almost 70% in 1980. During this period, the Brazilian population tripled and the urban population multiplied by seven. In 2010, the transport sector in São Paulo accounted for 71% of the total emissions released by the energy sector. Ethanol has been considered a fuel with less greenhouse gas emissions, when compared with fossil fuels. However, ethanol production would have to double to meet the expected demand. Electric vehicles (EVs) market is expanding around the world, and is also an option to reduce the transport emissions, if powered by clean electricity. To assess whether the adoption of EVs might bring more benefits than the current ethanol, we develop prospective scenarios supported by the Long-range Energy Alternatives Planning (LEAP) simulation tool, taking a bottom-up tank-to-wheel approach to consider the CO2 emissions of car in São Paulo. The scenario considering a substitution of 25% of gasoline-powered cars by EV in 2030 showed a reduction in energy consumption and CO2 emissions, around 15% and 26% respectively in that year in comparison with 2015. We discuss the interplay between ethanol and EV, also considering emission coefficients from life cycle analysis conducted in Brazil, and concluded EV will have higher positive impact on climate change mitigation than ethanol. 相似文献

More and more consumers are willing to pay a premium for fair trade products. However, great potential remains as the market shares of these products are still low. In the present study, neutralization theory was applied to investigate the reasons for consumers hesitating to buy more fair trade products. A postal paper‐and‐pencil survey was sent out using random addresses from the telephone book in the German‐speaking part of Switzerland, resulting in a final sample size of n = 620. The results show that the techniques of neutralization are used to various degrees. A principal component analysis resulted in two strategies of neutralization: an internal strategy (focusing on the consumers themselves) and an external strategy (focusing on the farmers in developing countries). A regression analysis proved that the internal neutralization strategy was an important predictor for fair trade buying behaviour, even when controlling for attitudes towards fair trade. 相似文献

Many inside mainstream academic marketing judge the discipline’s influence within the family of business disciplines (as well as in practice) to be in decline. Despite great research productivity, methodologies as sophisticated as any in the social sciences, and a large and rich literature, opinion and evidence suggest that academic marketing is the least influential of the mainstream academic business disciplines. Nevertheless, marketing’s decline is not inexorable. The purpose of this paper is to evaluate this perplexing situation by: (1) assembling and evaluating a number of expert opinions from within marketing; (2) exploring relations and patterns of influence among the leading academic journals in accounting, finance, management, and marketing and evaluating the position and influence of each field; (3) attempting to understand marketing’s problems; and (4) exploring avenues to move marketing back to its once prominent position among the business disciplines. 相似文献

Aims: To better understand the impact of the clinical course of multiple sclerosis (MS) and disability on employment, absenteeism, and related factors.Materials and methods: This study included respondents to the North American Research Committee on Multiple Sclerosis Registry spring 2015 update survey who were US or Canadian residents, aged 18–65 years and reported having relapsing-remitting MS (RRMS), secondary progressive MS (SPMS), or primary progressive MS (PPMS). The RRMS and SPMS participants were combined to form the relapsing-onset MS (RMS) group and compared with the PPMS group regarding employment status, absenteeism, and disability. Multivariable logistic regression was used to examine the relationship between employment-related outcomes and factors that may affect these relationships.Results: Of the 8004 survey respondents, 5887 (73.6%) were 18–65 years of age. The PPMS group (n?=?344) had a higher proportion of males and older mean age at the time of the survey and at time of diagnosis than the RMS group (n?=?4829). Female sex, age, age at diagnosis, cognitive and hand function impairment, fatigue, higher disability levels, ≥3 comorbidities, and a diagnosis of PPMS were associated with not working. After adjustment for disability, the employed PPMS sub-group reported similar levels of absenteeism to the employed RMS sub-group.Limitations: Limitations of the study include self-report of information and the possibility that participants may not fully represent the working-age MS population.Conclusions: In MS, employment status and absenteeism are negatively affected by disability, cognitive impairment, and fatigue. These findings underscore the need for therapies that prevent disability progression and other symptoms that negatively affect productivity in persons with MS to enable them to persist in the workforce. 相似文献
