The purpose of this paper is to study which factors affect consumer expenditure and how, when positional concerns matter. It also investigates how consumers finance and reallocate their expenditure, and modify their consumer baskets when members of their reference groups spend more on positional goods, and they do not want to lag behind.

A literature review is presented, and then a new model is developed from a behavioural economic perspective. It describes how consumers with various risk attitudes reallocate their consumer expenditure and modify their consumer baskets when consumption externalities influence their relative consumption due to a positional game, but they want to “keep up with the Joneses”.

Consumers with different risk attitudes finance and reallocate their consumption expenditures variously to sustain their relative positions. Risk-neutral, slightly and intermediately risk-seeking consumers achieve a lower utility level than others. They do not realise a utility-maximising consumer basket, as it includes a relatively low number of nonpositional goods, but this choice can be considered the best response in a positional game in order to sustain their relative position.

The relationship between positional and nonpositional goods is explicitly described. The model assumes that consumers can be classified based on their risk attitudes when positional concerns matter. It also describes how consumers with various risk attitudes reallocate their consumer expenditure when they want to sustain or improve their relative consumption in a positional game.

The purpose of this paper is to show that the environmental income drives economic growth of a large open country.

The authors detect that the relative environmental income has double effect of “conspicuous consumption” on the international renewable resource stock changes when a new social norm shapes to environmental-friendly behaviors by using normal macroeconomic approaches.

Every unit of extra demand for renewable resource consumption increases the net premium of domestic capital asset. Even if the technology spillovers are inefficient to the substitution of capital to labor force in a real business cycle, the relative income with scale effect increases drives savings to investment. In this case, the renewable resource consumption promotes both the reproduction to a higher level and saving the potential cost of environmental improvement. Even if without scale effects, the loss of technology inefficient can be compensated by net positive consumption externality for economic growth in a sustainable manner.

It implies how to earn the environment income determines the future pathway of China’s rural conversion to the era of eco-urbanization.

We test the tax incidence to demonstrate an experimental taxation for environmental improvement ultimately burdens on international consumption side.

Empirical studies show that years of schooling are positively correlated with good health. The implication may go from education to health, from health to education, or from factors that influence both variables. We formalize a model that determines an individual’s demand for knowledge and health based on the causal effects, and study the impacts on the individual’s decisions of policy instruments such as subsidies on medical care, subsidizing schooling, income tax reduction, lump-sum transfers, and improving health at young age. Our results indicate that income redistribution policies may be the best instrument to improve welfare, while a medical care subsidy is the best instrument for longevity. Subsidies to medical care or education would require large imperfections in these markets to be more welfare improving than distributional policies.

This paper aims to examine the effects of adding non-tradable sector and trade in intermediate goods sector and their impact on the “Backus-Smith” (BS) puzzle and the features of the non-tradable output. Conventional international real business cycle models show that the real exchange rate and the terms of trade are positively correlated to the relative consumption movement between the home and foreign economies when there is a total factor productivity shock, whereas the correlation in the data is negative. The author develops a two-country, dynamic, stochastic and general equilibrium (DSGE) model with staggered price setting in the non-tradable sector and international trade in intermediate goods sector because of product differentiation in a high-asset market frictions situation.

In this paper, DGSE simulation and calibration are performed using Matlab with Dynare.

When the world economy has positive country-specific productivity shock, the benchmark model with non-tradable sector and intermediate goods sector successfully solves the BS puzzle and is able to match several features of the data. The dynamic responses to productivity shock show that integrating product differentiation is necessary to generate a more volatile and counter-cyclical non-tradable output.

The paper investigates the effects of incorporating non-tradable sector and trade in interemediate goods sector to standard two-country DSGE model through simulation and calibration.

This paper aims to explore the impact intentional non-consumption has on consumer practices, the resulting consumption experiences and meanings attached to the actions of participants and what is learned from this relative to voluntary simplicity, most specifically when participants are asked to become voluntary simplifiers versus volunteering to do so.

A phenomenological approach was applied utilising unstructured interviews and autoethnography. Data were analysed through the theoretical lens of voluntary simplicity within the contexts of contemporary Irish consumer culture and the collapse of the Celtic Tiger.

The study highlights findings in four key areas: self-imposed parameters of intentional non-consumption and subsequent voluntary simplicity categories; motivations, practices and experiences of participants; the role intentional non-consumption plays relative to personal satisfaction, fulfilment and happiness; and how participant consumption practices reverted to “normal” once the study was complete.

This study focuses on an all-female group of participants; future research is warranted that explores the issue from a male perspective.

Findings are of particular interest to policy makers seeking to develop initiatives that reduce consumption practices and contribute to discussions that explore the role of consumption in modern society – in particular the wide-ranging debate on whether consumption leads to happiness and how consumers might be persuaded to consume in a more sustainable manner.

This study adopts an innovative methodology that explores voluntary simplicity and contributes to an understanding of consumption culture by exploring what happens when consumers are asked to reduce their consumption and become voluntary simplifiers. An extension of Huneke’s definition of voluntary simplicity is offered, which recognises the role non-material consumption plays in consumption practices, and explores voluntary simplicity relative not only to individuals’ values and beliefs, as discussed in the literature, but also to their lifestyle activities and wider sociocultural and institutional factors.

We examine the relationship between the business cycle and poverty for the period from 1960 to 2008 using income data from the Current Population Survey and consumption data from the Consumer Expenditure Survey. This new evidence on the relationship between macroeconomic conditions and poverty is of particular interest, given recent changes in antipoverty policies that have placed greater emphasis on participation in the labor market and in-kind transfers. We look beyond official poverty, examining alternative income poverty and consumption poverty, which have conceptual and empirical advantages as measures of the well-being of the poor. We find that both income and consumption poverty are sensitive to macroeconomic conditions. A 1 percentage point increase in unemployment is associated with an increase in the after-tax income poverty rate of 0.9–1.1 percentage points in the long run, and an increase in the consumption poverty rate of 0.3–1.2 percentage points in the long run. The evidence on whether income is more responsive to the business cycle than consumption is mixed. Income poverty does appear to be more responsive using national level variation, but consumption poverty is often more responsive to unemployment when using regional variation. Low percentiles of both income and consumption are sensitive to macroeconomic conditions, and in most cases, low percentiles of income appear to be more responsive than low percentiles of consumption.

The relevance of present consumption bias on personal finance has been confirmed in several studies and has important theoretical and practical implications. It has important, measurable implications when analyzing commitment or self-control, adherence to healthy habits (e.g. exercising or dieting), procrastination tendencies or savings. The purpose of this paper is to contribute to our understanding of these issues by postulating a model of income uncertainty within a hyperbolic discounting framework that measures the cost of financial intertemporal inconsistencies related to this bias. The emphasis is on the analysis of this cost. We also propose experimental designs and consistent estimation methods, as well as agent-based modelling extensions.

The authors develop a finite-horizon model with hyperbolic preferences. Individuals have a present bias distinct from their discount rate so their choices face intertemporal inconsistencies. The authors further extend the analysis with uncertainty about future incomes. Specifically, individuals live for three periods, and the authors find the optimal consumption levels in the perfect-information benchmark by backward induction. They then proceed to add biases and uncertainty to characterize their implications and measure the costs of the intertemporal inconsistencies they cause.

The authors measure how an agent's utility is greater when they “tie their hands” than when they are free to re-evaluate and change their consumption schedule. This “cost of being vulnerable to falling into temptation” only depends (increasingly) on the measure of the present bias and (decreasingly) on the discount factor. They analyze the varying effects on utility and consumption of changes in impatience and optimism. They conclude by discussing theoretical and practical implications; they also propose agent-based simulations, as well as empirical and experimental designs, to further test the relevance and applications of the results.

This model has important, measurable implications when analyzing commitment or self-control, adherence to healthy habits (e.g. exercising or dieting), procrastination tendencies or savings.

The results enhance the estimation of the costs of present biases such that employers can better identify the incentives required to acquire and retain human capital. The authors provide evidence that workers are vulnerable to contract renegotiations and about the need for a regulator that restores ex-ante efficiency. Similarly, in the private sector, firms could recognize the postulated consumer profiles and focus their resources on anxious, too-optimistic or potentially addictive consumers; this, again, provides some justification about the need for a regulator.

In traditional exponential discounting, the marginal rate of substitution of consumption between two points depends only on their distance; thus, it allows none of the intertemporal inconsistencies we often observe in real life. Therefore, hyperbolic discounting better fits the data. The authors model choice under uncertainty and focus on the costs caused when present biases (ex-post) push behaviour away from ex-ante optimality. They conclude by proposing experimental designs to further enhance the estimation and implications of these costs. The postulated refinements have the potential to improve previous analyses on commitment devices and commitment-related regulation.
