For more than a century, hand‐pulled rickshaws have been a prominent part of Calcutta's cityscape. Under the veil of modernization, progress, and globalization, however, the government of West Bengal State declared that rickshaws cause traffic congestion and constitute an exploitative use of human labor. Yet, despite the government‐imposed ban, rickshaws continue to ply the streets of central Calcutta. Based on interviews with rickshaw owners, operators, public officials, and local residents, we examine the cultural politics surrounding rickshaw pulling in Calcutta. This article shows that the rickshaw wallahs (pullers), who operate as part of the informal economy, provide an expansive range of services not limited to transportation. Indeed, the rickshaw wallahs form an integral part of Calcutta's social fabric, having made a place for themselves by facilitating social interaction and challenging hegemonic ideas and practices about who belongs where.  相似文献

The article discusses the importance of services as agents of internationalisation. Services are seen as dynamic agents of change, and services and commodities are considered composite in production processes. Modes of entering the global scene such as trade in services, foreign direct investment, forming of alliances, franchising and intrafirm trade are focused on, and limits to globalisation are highlighted. Some services, particularly advanced business services, more easily fall prey to institutional and cultural constraints than others. Empirically, Norway is analysed as an arena of international services against the background of its historical tradition particularly in shipping and affiliated activities. Recently, however, manufacturing has gained in importance, mainly in exports and to a lesser extent in imports, due to the petroleum economy. This appears to indicate that export of services has lost momentum over time. The development profile in shipping is highly negative. The negative picture changes somewhat when not only the trade balance, but also investment abroad is considered. In this respect, services have grown in relative importance, notably in the financial sector and in telecommunications. When juxtaposing outgoing and incoming investments, petroleum-related services have gained an increased export and investment surplus in recent years, from a balance in the mid-1990s.  相似文献

After the 1997 financial crisis, many retrenched workers preferred not to return to provincial homes but remained in Bangkok to establish informal retail businesses in branded and other consumer products. In contrast to traditional street vendors, who specialized in food items primarily catering for low‐income customers, and focused on high volume, these ‘new generation’ street vendors also adopted more formal business practices. Given their greater sophistication and better education, we hypothesized that they would be more organized advocates of vendors' rights and thus more prone to conflicts with municipal authorities. Based on interviews, however, we found that new generation vendors are adaptive to location and business strategy, and prefer a low profile in dealing with officialdom. By contrast, traditional vendors remained more tied to particular spaces, are more likely to stand up for their rights to use public space and, because they expect more from government, are more prone to conflicts with municipal authorities. Our findings relate to ongoing discussion on the rights and needs of street vendors to access urban public space and the responsibilities of authorities to meet and provide for these informal sector livelihoods that make up a significant share of the national economy in Thailand, as elsewhere in the global South.  相似文献
