Gender,generation and sustainable consumption: Exploring the behaviour of consumers from Izmir,Turkey

This study investigates the relationship between consumers’ sustainable consumption behaviour and both gender and generation‐related individual differences in a sample of Turkish consumers. A total of 393 participants from different generations and gender took part in the study. To measure sustainable consumption behaviour, we used four‐dimensional sustainable consumption behaviour scale. The results showed that generation is associated with unneeded consumption as a dimension of sustainable consumption behaviour. Consumers who are Baby Boomers found to have the highest level of unneeded consumption behaviour while Gen‐Zers have fewest. Additionally, data supported the association between gender and sustainable consumption behaviour. Women showed a higher level of sustainable consumption behaviour both in overall behaviour and tendency to reuse products. Taken together, the findings suggest that gender and generation of consumers can differentiate sustainable consumption behaviour. The implications of these findings, as well as the limitations and future directions, are also discussed.     

The economics of land fragmentation in the north of Vietnam*

Land fragmentation, where a single farm has a number of parcels of land, is a common feature of agriculture in many countries, especially in developing countries. In Vietnam, land fragmentation is common, especially in the north. For the whole country, there are about 75 million parcels of land, an average of seven to eight plots per farm household. Such fragmentation can be seen to have negative and positive benefits for farm households and the community generally. Comparative statics analysis and analysis of survey data have led to the conclusion that small‐sized farms are likely to be more fragmented, and that fragmentation had a negative impact on crop productivity and increased family labour use and other money expenses. Policies which allow the appropriate opportunity cost of labour to be reflected at the farm level may provide appropriate incentives to trigger farm size change and land consolidation. Policies which tip the benefits in favour of fewer and larger plots, such as strong and effective research and development, an active extension system and strong administrative management, may also lead to land consolidation.     

First-best tax policy,congestion, and imperfect competition

In the presence of imperfect competition and externalities -increasing returns to diversity and congestion -competitive equilibria are not efficient. Thus, the inefficiency can be modified by the introduction of appropriate fiscal policies. Under the consideration of an optimal fiscal policy, the results of this paper show that the government should pay a subsidy to labor and capital income in order to correct the production inefficiency. Furthermore, the optimal subsidy to fixed costs depends on the degree of increasing returns to diversity and the degree of congestion, and it decreases with the latter effect.

Pacific Basin stock markets and international capital asset pricing

In this paper, we follow Harvey (1991) to investigate whether rates of return on Pacific Basin stock markets can be explained by conditional version of International Capital Asset Pricing Model (ICAPM), which allows for time-varying expected returns, variances, and covariances. The results show that most individual Pacific Basin markets can be described by the conditional ICAPM. However, the multiple markets' tests do not support the conditional ICAPM formulation, and the estimates of world reward to risk ratio are not the same across these markets. Furthermore, the Ghysels and Hall test (Ghysels & Hall, 1990a, 1990b) shows that the estimates of parameter are also unstable in the conditional ICAPM formulation. This implies that it is difficult to use world return to describe the relationship between expected return and risk for the Pacific Basin stock markets.     

Business responses to climate change: strategies for reducing greenhouse gas emissions in Vietnam

This study identifies the climate change strategies adopted by firms in developing countries to reduce their greenhouse gas (GHG) emissions. First, a framework is developed to classify and assess the GHG emission strategies of companies; second, it is then improved by using data on their implementation collected from 185 companies operating in 10 energy-intensive industries in Vietnam. We find that multinational subsidiaries engage in various climate change activities and have a higher level of implementation than those of domestic firms. Further, the most active and proactive companies are large in size and from Europe, the United States and Japan.     

Level of access and infrastructure investment in network industries

In this paper, we study how the terms of access to an incumbent’s infrastructure (i.e., the level of access and price) affect an entrant’s incentives to build its own infrastructure. Setting a high level of access (e.g., a resale arrangement), which requires relatively small up-front investment for entry, accelerates market entry, but at the same time delays the deployment of the entrant’s infrastructure. This is also true for a lower access price. We show that the socially optimal access price can vary non-monotonically with the level of access. We also study the case where access is provided at two different levels, and show that access provision at multiple levels can delay infrastructure building. Finally, we modify our baseline model to allow for experience and/or market share acquisition via access-based entry, and show that high levels of access may accelerate facility-based entry.     

Team control mode,workers' creativity,and new product innovativeness

Scholars of creativity and innovation argue that successful innovations originate from the creative ideas of workers. However, few studies have empirically examined how management mechanisms, such as the control mode adopted by the new product development team, may work together with workers' creativity to deliver a successful new product. Drawing on the theory of opposing action strategies of team innovation, we propose that different team control modes may work together with team members' creativity to jointly influence the innovativeness of teamwork outcomes. With survey data collected from different sources in new product development teams, we find that restrictive control can effectively help teams composed of very creative members to successfully develop innovative new products. Conversely, promotive control can effectively help teams composed of less creative members to deliver innovative new products.
