Today, a large share of cost, congestion, and emission in cities is attributed to light goods vehicles like carrier vans distributing to the last mile. The aim of many policy agendas is to reach cleaner cities with less disturbance from the distribution vehicles. Several suggestions have been put forward and tested in research and practice, such as access restrictions, multimodal transport, and use of cleaner vehicles. In this paper, we develop a case for a more sustainable freight distribution within cities using an ex ante case study. The idea of the mobile depot is built on the iteration between historical transitions within cities and contemporary developments in urban freight distribution, and then analyzed ex ante both quantitatively in calculations and qualitatively in two stakeholder workshops. The idea is integrated and multimodal, based on a mobile depot (e.g., a bus, truck, barge, or tram) that circles the city and connects to low emission last mile delivery options such as LEVs (Light Electrical Vehicles) or cargo bikes. We found that such a system can be environmentally and socially better for the city context, while maintaining economic viability above a certain utilization rate of the mobile depot for the transport operators. 相似文献

Prior studies have defined high-growth firms (HGFs) in terms of growth in firm employment or firm sales, and primarily analyzed their contribution to overall employment growth. In this paper we define HGFs using the commonly applied growth indicators (employment and sales), but also add definitions based on growth in value added and productivity. Our results indicate that HGFs in terms of employment are not the same firms as HGFs in terms of productivity, and that their economic contributions differ significantly. Economic policy promoting fast growth in employment may therefore come at the cost of reduced productivity growth. Although HGFs of different definitions may not be the same firms, young firms are more likely to be HGFs irrespective of definition. This suggests that economic policy should focus on the conditions for new firm formation and early growth of firms, rather than target a particular type of HGFs. 相似文献

This paper proposes time-varying idiosyncratic risk as a component driving conditional abnormal returns and outlines a corresponding Engle et al. [Econometrica 55 (1987) 391] ARCH-M market model. An application is given to initial public offering (IPO) aftermarket stock returns, where a positive relation between idiosyncratic risk and returns is consistent with young issues’ equity as a contingent claim on firm assets. The empirical results for an illustrative sample of German Neuer Markt stocks traded during the first two years after initial listing indicate pronounced skewness as well as a positive relation between conditional idiosyncratic risk and expected returns. Conditioning aftermarket performance on risk yields much lower levels of abnormal return significance than a standard approach. 相似文献

Sparking financial bubbles are irrational impulses—from mania to panic—that play a major role in collective human investment behavior. Contradicting the rational man theory, bubbles keep occurring. But to disregard its influences as aberrations have only rendered conventional economic theory as abstract academia with little practical value. However, allowing for the juxtaposition between the concepts of archetypes and the collective unconscious, as coined by the Swiss psychologist Carl Gustav Jung, and the generic anatomy of financial bubbles could provide fertile ground for an improved understanding of the seemingly irrational behavior. The author aims to demonstrate the workings of archetypes and proposes a measurement methodology designed to capture the subliminal forces that influence investment decisions. 相似文献

A real-options approach was used, incorporating uncertainty and irreversibility of investments, to study the number of stores entering the Swedish retail food market during the period 1994–2002. It was found that uncertainty affected the entry-decision. Entry was less frequent in highly concentrated local retail food-markets characterized by a high degree of uncertainty, whereas higher profit opportunities seem to have increased the probability of entry. 相似文献

Die zunehmende Discountausbreitung fordert Hersteller und Detailh?ndler heraus, den Mehrwert ihrer Produkte besser aufzuzeigen. Es braucht Argumente jenseits des Preises. Stellt die Kommunikation transparenzf?rdernde Informationen zur Lieferkette der
Produkte in den Vordergrund, werden bislang kaum evidente, aber aus Konsumentensicht entscheidende, Unterschiede aufgezeigt,
die Konsumenten helfen, beim Einkauf nicht nur einseitig auf den Preis zu achten. 相似文献
