The first wave, conducted in 2002–2003, of an in-depth panel survey in Quebec City, was used to compare the out-of-home activities of adults who had the use of mobile phones, or of internet at home, to those who did not. A unique feature of the survey was the inclusion of respondents’ perceptions of the both the temporal and the spatial flexibility of all executed activities. We find, after statistical controls for other factors, that mobile phone use was positively associated with activity and trip levels, while internet access was negatively associated. These two ICTs also had mostly opposite relationships with the routinisation and pre-arrangement of activities and with some conventionally defined sub-classes of activity. 相似文献

When commodity prices rise, wholesalers and retailers of products derived from basic commodities respond by passing along at least a portion of the price increase to consumers. In this paper we examine whether firms respond differently to positive commodity price shocks than to negative commodity price shocks; that is, whether commodity price volatility alters market power. We exploit recent volatility in food commodity prices over the period 2007-2010 to investigate how commodity price shocks translate into market power in two different vertically-structured food product industries: potatoes and fluid milk. For potatoes, we find both wholesale and retail market power decreases (increases) during periods of rising (falling) commodity prices. Moreover, price-cost margins widen a substantially greater degree in response to negative shocks than margins narrow in response to positive shocks, indicating that commodity price volatility increases market power. For fluid milk, we find that market power likewise declines during periods of rising commodity prices; however, market power does not significantly change during periods of falling commodity prices, suggesting that commodity price volatility decreases market power. 相似文献

Consequences of free-trade agreements (FTAs) among the ASEAN+3 and ASEAN+6 countries are explored using a dynamic computable general equilibrium (CGE) model. Quantitative assessments of intra- and extra-regional effects on welfare, trade and output are offered. When both trade facilitation and endogenously determined productivity are included in the FTA scenarios, Singapore, other ASEAN countries and China would be able to realize relatively large welfare gains, while the welfare effects on the EU and North America are negligible. The trade and output effects on the latter two regions are also relatively small, with the notable exception of crops, other than rice, in North America. 相似文献

The paper describes the current situation in the salt industry. It points to the inadmissibly high and expanding market share of imported salt products despite the country’s own colossal resource base and the domestic enterprises’ huge unused capacities. It has been shown that OAO Russian Railroads (OAO RZhD) will economically benefit due to its reasonable policy of selective reduction of the railroad shipment tariffs for salt for domestic producers due to the inevitable growth of the country’s own salt output. 相似文献

The necessity of institutional proposals on the stable development of rural territories is justified in the article. A multivariant approach is proposed for studying the institutional environment of the countryside. The key trends of reformation of the countryside’s social and economic systems are defined based on the results of the our own empiric research. 相似文献

Accounting for and ownership of U.S. private employee pensions has long been a controversial and politically contested terrain. The uniqueness in the U.S. of using employers as the principal provider of pensions makes the reporting of pensions more problematic since the corporate employers providing pensions are not strictly accountable to only the pensioners. Over the last quarter century there has been a marked swing in power toward management and away from employees making it possible for increasing numbers of U.S. companies to switch from conventional defined benefit plans to cash balance plans. This paper provides a “case” study of how accounting standard-setters framed the pension reporting problem vis-à-vis how they frame the “reporting problem” in general. Utilizing various sources of commentary about the phenomenon of cash-balance conversions, we triangulate on the pension problem to demonstrate how current FASB disclosure rules fail to satisfy the condition of neutrality and how those rules have facilitated the shifting of economic risk from shareholders to employees. 相似文献

For the purpose of equipping researchers in marketing with a more sophisticated method to measure alienation in a marketing
context, the authors have constructed and initially tested an alienation from the marketplace index. Alienation is defined
in terms of Melvin Seeman's (1959) five basic variants of alienation: powerlessness, meaninglessness, normlessness, social
isolation, and self-estrangement. After pretesting, two questions per variant of alienation remained as the operational measures
of alienation from the marketplace. These questions focused specifically on marketing phenomenon. Test-retest reliability
was tested with 35 paired observations. Validity was checked with survey data from 140 households. In terms of face or content
validity, the questions met the criterion of “looking as if” they should indicate the corresponding dimensions of alienation.
Correlations between the marketplace alienation items and a measure of general alienation established concurrent validity.
The authors propose that the use of the marketplace alienation index in studies involving those who are affected by our country's
business climate may prove useful. For example, one would hypothesize that increasing alienation from the marketplace would
be associated with support of consumerist goals, or even of additional government legislation to control problems that the
individual feels is uncontrollable by him because of the bigness and indifference of modern day enterprise.

This paper reports a qualitative study conducted at four Japanese subsidiaries in China and Vietnam about their process of international knowledge transfer. Building on the literatures concerning the diverse types and characteristics of knowledge in multinational corporations (MNCs), we explore the broad mechanisms adopted and locally generated by the host country subsidiaries for transferring the foreign knowledge and putting the locally embedded knowledge into practical use at the local settings. The findings indicated (1) the limitations of applying a standardized and universal set of knowledge transfer mechanisms without considering local idiosyncrasies and (2) the contributions of local agents and institutions throughout the process of local knowledge adaptation and development. 相似文献

Upland areas provide UK society with many important functions, goods and services, but have experienced a number of disturbing trends and face an uncertain future. This paper outlines historic, current and future drivers of environmental, economic, socio-cultural and policy change in UK uplands, and assesses how these have affected or are likely to affect ways in which land is used and the provision of ecosystem services. Information is synthesised into scenarios summarising a range of possible futures anticipated for UK uplands to 2060 and beyond. Finally, innovations in science, technology, governance and policy are evaluated that could enable uplands to continue providing key ecosystem services under a range of scenarios. The paper concludes that many upland areas will need to be prepared for significant reductions in grazing and prescribed burning. Conversely, other areas could experience agricultural intensification, for example significant increases in grazing or an expansion of arable or bioenergy crops into upland valleys, due to anticipated increases in global demand for food and energy. These scenarios will take place in the context of climate change. Many may take place together and may interact with each other, with complex and unpredictable implications for the upland environment, economy and society. In this context, a number of advances are needed in science, technology and policy to maintain viable upland communities and the future provision of ecosystem services. These may include funding for ecological and hydrological restoration via carbon offsetting or other means. It may also involve advances in ecosystem service modelling, mapping and valuation, which through stakeholder participation could facilitate more integrated rural planning. New forms of environmental governance need to be explored that can empower those interested in developing upland economies to maintain thriving upland communities, while managing the ecosystem services they provide as efficiently as possible. 相似文献
