Fashion, growth and welfare: an evolutionary approach

The task of this paper is to explore the interplay between fashion, consumer lifestyles and economic growth in the context of a world of technological change in which the menu of possibilities that consumers face is constantly changing and tending to increase in length. Our working definition of ‘fashion’ is simple, namely the tendency or behavioural norm of actors to adopt certain types or styles of customs or commodities nearly simultaneously, only to adopt a different type or style of custom or commodity in future periods. The demand spikes associated with fashion may pertain to newly introduced products or to products that have been around for some time; they may also occur in hybrid cases where a seemingly defunct product or genre is given a brief rebirth by being reincarnated in terms of a new technology.

The implications of income dependent equivalence scales for measuring poverty in Sri Lanka

Purpose The purpose of this paper is to test whether household preferences satisfy the assumption of base-independence, to examine the effects of household income on equivalence scales and thereby food consumption economies of scale and to examine how far conventional poverty rates require adjustment when scale economies in food consumption are taken into consideration. Design/methodology/approach To achieve these aims, the authors use a Pendakur (1999) adaptation of the test of base-independence, and income dependent Engel (1895) equivalence scales. Findings In Sri Lanka, the hypothesis of base-independence is rejected: the equivalence scales increase with household income both at the national and the sectoral level, that is urban, rural and estate sectors. This suggests that low-income households enjoy greater scale economies. After adjusting for scale economies, urban, rural and estate poverty headcount ratios decline by 3.2, 8.8 and 13.7, respectively, while at the national level the decline is about 8.3. Research limitations/implications The results are based on the assumption that all of the adults in the households have identical tastes, irrespective of their gender and age. Furthermore, the survey data exclude three districts in the northern province of Sri Lanka due to resettlement activities took place after the civil war. Practical implications Higher scale economies among the poor imply that poverty among low-income households is overstated when using traditional measures of poverty rates. Originality/value The novelty of this paper is that it provides insights on the effect of income on food consumption economies of scale and implications of this phenomenon on poverty estimates in the context of a developing country like Sri Lanka.

Measuring the diversity of household spending patterns

Households tend to diversify their spending across a wide range of goods and services as they become more affluent. Recently, there has been growing interest in understanding the precise manner in which this spending diversification process takes place. We review what facts are known about this process and the underlying behavioural tendencies that are thought to drive it. In addition, we clarify the relationship between different approaches to measuring the level of spending diversity. A number of indices are employed, including measures based on joint probabilities, distances and the concept of entropy. Using UK household spending data, we show the extent to which these measures deliver different results and shed light on the nature of behavioural heterogeneity.

Escaping Satiation Dynamics: Some Evidence from British Household Data

Summary The tendency of sectoral demand to satiate has long been argued to be a key driver of the structural change in an economy (Pasinetti 1981; Saviotti 2001). This literature raises the question as to what extent cross-sectional patterns of household expenditure can be used to make inferences about how the demand for goods and services will grow over time. Moreover, if indeed satiation does take place, then firms and entrepreneurs could react to this situation by innovating goods and services in order to overcome stagnation in demand growth (Witt 2001). We empirically investigate this ‘satiation-escape’ hypothesis by examining the inter-temporal dynamics of Engel curves and their derivatives, which reflect how household spending on a good changes with income. Taking into account changes in the price level, we investigate whether Engel curves that exhibit cross-section satiation tend to exhibit over time an upwards shift in the satiation level jointly with a shift in position and shape. Evidence suggests that this is actually the case.

Consumer Specialization and the Demand for Novelty: a Reconsideration of the Links and Implications for Studying Fashion Cycles in Tourism

Summary How does the consumer’s predisposition to seek arousing new sensations affect their tendency to accumulate knowledge about consumption activities? Using recent insights about the dynamic interaction of learning mechanisms that are part of the individual’s genetic endowment, we argue that, contra Scitovsky (1976), the emergence of relatively convenient forms of entertainment may foster - rather than inhibit - the accumulation of consumer knowledge. Furthermore, because specialized consumers have a greater tendency to innovatively modify aspects of the consumption activity, we argue that this specialization process fundamentally affects the rate at which consumers become habituated to novelty. This represents an important way in which cognitive learning patterns interact with non-cognitive learning dynamics and it has consequences for understanding the direction and length of fashion cycles in recreational activities. In particular, we discuss how this perspective can be applied to studying tourism demand patterns and the ‘Destination Life Cycle’.

Have Australia's tourism strategies incorporated climate change?

ABSTRACT Tourism is widely acknowledged as a key contributor to climate change, but it remains unclear how the tourism industry has been planning for climate change in practice. This paper conducts the most comprehensive critical review of Australias tourism policy and planning documents to date. The paper explores the complex challenges posed by climate change to tourism and how tourism policy has been adapting over a 15-year period. Drawing on a longitudinal data-set of 477 Australian tourism policy and planning documents at the national, state, regional and local level, this research analyses the strategic discourse on climate change using content analysis and bibliometrics. The findings reveal opportunities, challenges and strategies for the tourism industry to contribute to the sustainable management of climate change. Opportunities include developing more “green” products, while strategies include establishing and/or participating in collaborative climate change schemes and strengthening dialogue surrounding climate change to aid the implementation of sustainable practices. Future research should consider the broader policy-making environment, such as the stakeholders, power and interest dynamics when analysing tourism strategies in relation to climate change.

Examining Dutch disease across Australian regions

The recent mining boom represents one of the largest external shocks to the Australian economy in its post‐war history. Although most agree that it had a positive effect on the Australian economy as well as on people’s living standards, there is disagreement over the extent to which this boom has caused deindustrialisation and the so‐called Dutch disease in Australia. Our empirical findings support the presence of Dutch disease nationally for Australia using data for the period 1984–2013. Regionally, the results show that Dutch disease was concentrated mainly in the eastern and southern states of Australia—Victoria, Queensland, South Australia and Tasmania.

Domestic technology, consumption economies of scale and poverty: evidence from Sri Lanka

ABSTRACT While it is well known that new technologies enhance consumer welfare, the manner in which these technologies impact the ability to realize economies of scale in consumption is not well understood. We use Sri Lankan household data to examine how the adoption of new technologies by households positively impacts their ability to achieve household economies of scale. This suggests that new technologies not only deliver a greater variety of consumption goods to consumers, but they may also play an important role in enabling large households to escape poverty by lowering the per-capita costs of maintaining a given standard of living. Given the importance of consumption economies of scale in the measurement of poverty, this study provides some insights on the extent to which the number of poor households changes when food consumption scale economies due to technology adoption in the domestic sphere are incorporated.
