This paper studies one‐dimensional Ornstein–Uhlenbeck (OU) processes, with the distinguishing feature that they are reflected on a single boundary (put at level 0) or two boundaries (put at levels 0 and d > 0). In the literature, they are referred to as reflected OU (ROU) and doubly reflected OU (DROU), respectively. For both cases, we explicitly determine the decay rates of the (transient) probability to reach a given extreme level. The methodology relies on sample‐path large deviations, so that we also identify the associated most likely paths. For DROU, we also consider the ‘idleness process’ Lt and the ‘loss process’ Ut, which are the minimal non‐decreasing processes, which make the OU process remain ≥ 0 and ≤ d, respectively. We derive central limit theorems (CLTs) for Ut and Lt, using techniques from stochastic integration and the martingale CLT. 相似文献

We examine natural disasters and long‐run climatic factors as potential determinants of international migration, implementing a panel dataset of bilateral migration flows from 1960 to 2000. We find no direct effect of long‐run climatic factors on international migration across our entire sample. These results are robust when conditioning on origin‐country characteristics, when considering migrants returning home, and when accounting for the potential endogeneity of migrant networks. Rather, we find evidence of indirect effects of environmental factors operating through wages. We find that epidemics and miscellaneous incidents spur international migration, and there is strong evidence that natural disasters beget greater flows of migrants to urban environs. 相似文献

Individuals, differing in productivity and life expectancy, vote over the size and type of a collective annuity. Its type is represented by the fraction of the contributive (Bismarckian) component (based on the worker's past earnings) as opposed to the non‐contributive (Beveridgean) part (based on average contribution). The equilibrium collective annuity is either a large mostly Bismarckian program, a smaller pure Beveridgean one (in accordance with empirical evidence), or nil. A larger correlation between longevity and productivity, or a larger average life expectancy, both make the equilibrium collective annuity program more Beveridgean, although at the expense of its size. 相似文献

En el presente artículo se analizan los complejos procesos legislativos y judiciales necesarios para establecer el derecho de coparentalidad en la reglamentación laboral italiana. Tras identificar en el ordenamiento jurídico la tendencia a equiparar la protección de la familia con el apoyo a la mujer y a la maternidad, se investiga la evolución legislativa que ha llevado a reconocer al padre como pilar fundamental en la crianza de los hijos. Por último, se analiza en detalle la jurisprudencia que, con su interpretación de los principios legislados, ha contribuido a superar la resistencia de la cultura patriarcal al cambio. 相似文献

Interest: This research analyses the influence of situations on salespersons’ gestures and behaviors. This research contributes to this underresearched field by exploring the impact of stressful versus nonstressful situations on salespersons’ personal behavior.Methods: This research is based on 1,205 gestures observed during 382 sales calls that averaged 11 minutes with 382 salespersons. Half were in stressful situations, and half were in nonstressful situations. This study focuses on pharmaceutical products (drugs) in the medical field, with 95 doctors, 6 judges, 304 average performing salespersons, 39 high performers, and 39 low performers. This study shows how salespersons’ behaviors vary depending on stressful and nonstressful situations. This research also articulates a new field of sales research that is understudied by researchers and suggests new training trends in sales management.Objective: The objective is to answer questions such as “Does stress influence salespersons’ behavior, and what are the gestures most affected by such situations?” To examine the effects of training on gestures, an experiment with 97 salespersons was conducted during a sales training session. This experiment measured whether salespersons trained on gestures behaved differently than those who were untrained.Results: In general, stressful or nonstressful situations caused real differences in gestural behavior. In particular, the best salespersons performed the largest number of gestures during stressful situations. For example, stressful situations increased the mechanical or emotional gestures in leg movements or the number of glances. 相似文献

In 2014 democracy in South Africa was 20 years old. The democratic government in 1994 inherited both a high and increasing public debt/gross domestic product ratio and significant development backlogs. The government had to establish fiscal sustainability, yet also pursue development in a sustainable way. This article explores the government's performance in reconciling fiscal sustainability with sustainable development. The article shows that fiscal policy has been sustainable over the 20 years, with some risks appearing towards the end, and that the government pursued sustainable development through reallocating resources within the budget and by spending more in real terms. Three phases can be identified: 1994–2000, 2001–08 and 2009–13. However, poor service delivery and low levels of government investment during the 20 years threaten to undermine economic growth. Lower growth consequently threatens the sustainability of both fiscal policy and development, which, in turn, again undermines growth prospects. Hence, the article also identifies key future challenges. 相似文献

The Economic Relevance of Environmental Disclosure and its Impact on Corporate Legitimacy: An Empirical Investigation 下载免费PDF全文
In determining its environmental disclosure strategy, a firm's management faces a tension between responding to the information needs of financial markets and maintaining its legitimacy within the community. In this paper, relying on information economics and legitimacy theory, we explore how firms resolve this tension. Results show that a firm's environmental disclosure enhances the quality of analysts' information context, which ultimately allows them to make better forecasts. Moreover, financial analysts seem to be able to decipher environmental information, discounting discourses that are inconsistent with a firm's underlying environmental performance. We find also that a firm's environmental disclosure serves another purpose, as it influences how its other stakeholders (beyond financial ones) perceive its legitimacy. Such enhanced legitimacy reduces the information uncertainty faced by financial analysts. Our results suggest also that both economic‐based environmental disclosure and sustainable development and environmental disclosure are useful to analysts in making their forecasts and enhance a firm's legitimacy.

Offshoring is generally believed to be productivity enhancing and this belief is underpinned by economic theory. This paper estimates the impact of materials and business services offshoring on productivity in Belgium over the period 1995–2004. It contributes to the literature: (i) by examining this issue separately for manufacturing and market services industries and (ii) by investigating the possibility of forward and backward spillovers from offshoring, i.e. that productivity gains from offshoring feed through to upstream and downstream industries. Results show that materials offshoring has no effect on productivity, while business services offshoring leads to productivity gains in manufacturing. Furthermore, there is no evidence of either forward or backward spillovers from offshoring. 相似文献

This article assesses the impact of armed conflict on the drinking water service of Basrah from 1978 to 2013 through an ‘urban warfare ecology’ lens in order to draw out the implications for relief programming and relevance to urban studies. It interprets an extensive range of unpublished literature through a frame that incorporates the accumulation of direct and indirect impacts upon the hardware, consumables and people upon which urban services rely. The analysis attributes a step‐wise decline in service quality to the lack of water treatment chemicals, lack of spare parts, and, primarily, an extended ‘brain‐drain’ of qualified water service staff. The service is found to have been vulnerable to dependence upon foreign parts and people, ‘vicious cycles’ of impact, and the politics of aid and of reconstruction. It follows that practitioners and donors eschew ideas of relief–rehabilitation–development (RRD) for an appreciation of the needs particular to complex urban warfare biospheres, where armed conflict and sanctions permeate all aspects of service provision through altered biological and social processes. The urban warfare ecology lens is found to be a useful complement to ‘infrastructural warfare’ research, suggesting the study of protracted armed conflict upon all aspects of urban life be both deepened technically and broadened to other cases. 相似文献
