Measuring fossil resource inequality—A case study for the UK between 1968 and 2000

This paper quantifies fossil resource inequalities amongst income quintiles in the UK between 1968 and 2000. It calculates a resource-based Gini coefficient using an input-output based resource allocation model.The results show that the Gini coefficient for total fossil resource consumption grew by 24% over the time period. By comparison the Gini coefficient for overall household expenditure rose by only 13%. The increase in resource inequality was prompted by the rising demand by high income quintiles for goods and services such as: “fuel and light” (heating and lighting the home), “car use” (private transportation), “recreation”, “travel” and “other services”. The analysis shows further that the Gini coefficient for “direct” fossil resources (“fuel and light” and “car use”) was lower and rose less steeply than the Gini coefficient for fossil resources embodied in other goods and services (indirect fossil resource requirements).Investigation into the drivers behind direct and indirect resource inequalities suggests a number of policy conclusions. Firstly, it is clear that policy initiatives to reduce fossil resource requirements (and the associated climate change impacts) must pay careful attention to distributional differences. Additionally, increased attention needs to be paid to the inequalities associated with indirect fossil resources consumption as well as the more visible direct resource inequalities.

Second-Best Pollution Taxes: an Analytical Framework and Some New Results

This paper compares the second-best optimal tax on polluting consumption goods with the Pigovian tax, which would internalize marginal environmental damage at a second-best optimum. It is shown that the relationship between the optimal tax on polluting consumption and the Pigovian tax is determined by the substitutability between labour and polluting consumption or clean and polluting consumption, depending on whether a wage tax system or a commodity tax system is being considered. The key factor determining the relationship between the two taxes is gross substitutability between the two taxed goods. As long as there is gross substitutability, the optimal dirt tax exceeds the Pigovian tax. The opposite can occur if and only if the two goods are gross complements.     

Import prices,income, and inequality

We compare three theoretical explanations for the positive empirical relationship between importer income per capita and traded goods prices. A first explanation is that consumers with higher incomes demand higher quality goods with higher prices. A second explanation is that wealthier people exhibit an increased willingness to pay for necessary goods as more goods enter the consumption set in a hierarchic demand system, and can thus be charged higher markups. A third explanation is that consumers with higher incomes are more finicky regarding their preferred variety in an ideal variety framework and can thus be charged higher markups. We discriminate between these three theories by focusing on the effect of income inequality on trade prices. Based on a large dataset with bilateral HS6 level data on 1260 final goods categories from more than 100 countries between 2000 and 2004, we find a highly significant negative effect of income inequality on unit values. This contradicts both the demand for quality and finickyness theories, while providing support for the increased willingness to pay theory linked to hierarchic demand. These findings on income inequality do not falsify the quality expansion model and the ideal variety model per se. However, the results do argue for place of importance of hierarchic demand.     

Real exchange rate shocks on tradables,nontradables, and the current account: Mexico, 1980–2000.

Effects of external and income shocks on consumption and on the current account in Mexico from 1980 to 2000 are investigated. An intertemporal model captures the extent into which non-traded goods consumption affects traded-goods consumption, clarifying the roles of intratemporal or intertemporal substitution. Vector autoregressions (VARs) show that the 1% shock to non-traded goods consumption affects traded-goods consumption by −2% immediately, reverting to zero only after one year, supporting the intratemporal channel. Real exchange rate (RER) shocks exert considerable macroeconomic fluctuations. The 1% shock to RER affects traded goods consumption by −2% immediately, reaching −5% one year later. At the expense of income shocks, RER shocks grow in explanatory power over time: from 20%–25% at 1 quarter to 65%–69% of the variance of traded goods consumption 3 years later. Figures for the current account range from 14% to 68%, while income shocks appear less important. In contrast, for non-traded goods, RER shocks roughly match the quantitative importance of income shocks, reinforcing the theoretical analysis.

Examination and Approval of New Patents in an Endogenous Growth Model

This study introduces the examination duration for newly developed goods into a standard R&D-based growth model. Producing such goods requires approval from an authority, and their examination incurs both cost and time. Thus, there is a lag between invention and production. This study investigates the effects of reducing the examination duration on examination backlogs (the number of newly invented goods under examination), economic growth, and welfare. We obtain an inverted-U shaped relationship between backlogs and duration, because reducing the duration decreases backlogs by accelerating the examination process, but simultaneously increases backlogs by promoting R&D and increasing the number of applications. In addition, we demonstrate that reducing the examination duration promotes economic growth. However, a rather short examination duration needs considerable resources as the examination has a higher cost. Thus, an extremely short duration hurts welfare. Our numerical analysis reveals the existence of an optimal examination duration.     

THE TREND IN RETIREMENT*

A model with leisure production and endogenous retirement is used to explain declining labor force participation rates of elderly males. The model is calibrated to cross‐sectional data on labor force participation rates of U.S. males by age, their drop in consumption, and leisure good expenditure share in 2000. Running the calibrated model for the period 1850–2000, a prediction of the evolution of the cross‐section is obtained. The model accounts for more than 87% of the increase in retirement of men over 65. The increase in retirement is driven by rising wages and falling prices of leisure goods.     

A generalized impure public good and linear characteristics model of green consumption

This paper provides a general framework for understanding consumer behavior related to goods and services that may be considered environmentally friendly, ethically produced, fairly traded, or some combination thereof. We generalize the impure public good model and derive its comparative static properties. The model accounts for any number of impure public (green) goods and joint production of any number of both private and public characteristics. The generalization provides a bridge between the impure public good model and the well-known linear characteristics model, both of which are special cases of the model developed here. The results show how demand for green goods and characteristics such as environmental quality depends on wealth, exogenously given levels of public goods, and the technologies of joint production. The effects of changes in technology depend critically on whether jointly produced characteristics are complements or substitutes in consumption. Several of the results are rather counterintuitive and differ in meaningful ways from existing models of impure public goods and linear characteristics. The results also illuminate several reasons for greater caution about whether it is reasonable to assume that green goods and services are necessarily beneficial for the provision of public goods.     

Public goods, merit goods, and the relation between private and government consumption

In this paper, we investigate the relation between public and private consumption, by constructing a general government spending data set, by function, for 12 European countries. In particular, we split government consumption into two categories. The first category—“public goods”—includes defence, public order, and justice. The second category—“merit goods”—includes health, education, and other services that could have been provided privately. Equations from a relatively general permanent income model are estimated by GMM. The estimates are fairly robust in showing that public goods substitute while merit goods complement private consumption. However, the relation between merit goods and private goods turns out to be stronger than that between public goods and private goods. Thus, in the aggregate government and private consumption are complements.     

How product innovation in the North may immiserize the South : A new look at the Ricardian model with a continuum of goods

The paper proposes a theoretical model investigating the welfare consequences of technological shocks in a Ricardian framework (a la Dornbush, Fisher and Samuelson, 1977). Contrary to the existing literature, the model incorporates a nonhomothetic demand function whose price and income elasticities are endogenously determined by technology. Nonhomothetic preferences are modeled as the result of the hierarchical consumption of luxury and necessity goods. The nature of technical progress determines the consumption pattern and notably the magnitude of the substitution effect between necessities and luxuries. The model is applied to the case of trade between two economies with different development levels. It is shown in particular that the developing country can suffer a fall in utility as a result of technical progress in the developed country biased towards luxury goods. This configuration depends on the size of the development gap and reflects the fact that Southern goods are less attractive, the higher the range of goods consumed. This result suggests that there is an optimal level of development gap to avoid LDCs being harmed by technical progress in the North.     

Local Manufacturing Hurt by Depreciations in a Theoretical Model Reflecting the Australian Experience

The model is motivated by data showing that the Australian production of local manufactures is hurt by depreciations and invigorated by appreciations. The paper briefly presents such evidence and then proceeds to a theoretical analysis. The model aims to capture short‐to‐medium run exchange rate effects in an economy with goods and services aggregated into four commodities: (i) imports; (ii) local manufactures; (iii) services; and (iv) rural goods (agricultural, pastoral, forestry, fishing and mining products). With the exception of rural goods, each commodity comprises consumer goods as well as inputs into the other sectors. Rural goods enter consumption only indirectly after processing by the manufacturing sector. Exports are exclusively rural goods. The model has a Keynesian flavour in that the production of local manufactures and services is not constrained by the availability of resources and of labour. Variable inputs per unit of output are assumed to be constant. There are also fixed inputs. Variable inputs are imports in the case of the import sector; rural goods and imports in the case of the local manufacturing sector; and labour in the case of the services sector. The prices of imports, local manufactures and services are set by constant mark‐up factors on variable costs. This assumption is based on a picture of imperfect competition with constant elasticity of demand at the firm level. The extreme capital intensity of rural goods production is taken into account by modelling total production of rural goods as an exogenous parameter. The price of rural goods is determined in the export market. It falls with increasing exports. The economy is not assumed to be small in its export market. The domestic consumption demand schedule is modelled as predetermined in the sense that in the time span under consideration the relationship between quantities consumed and nominal prices is not affected by the exchange rate. The nominal wage rate is assumed to be predetermined in the same sense. No specific functional form is imposed on the consumption demand schedule: the analysis is based on general assumptions, mainly non‐inferiority and gross substitutability. In view of gross substitutability, there is a competitive relationship between imports and local manufactures. Adepreciation raises the price of imports and ceteris paribus such an increase raises the consumption of manufactures. However, the analysis shows that this enhancing influence of a depreciation on manufacturing is weaker than other causal channels that work in the opposite direction. An increase in the price of imports (and exportables) raises variable costs and thereby the price of local manufactures. This leads to a decrease in the output of local manufactures. In the course of the analysis, it is first shown that a uniquely determined equilibrium exists for every exchange rate above a lower bound. Then the effects of a change in the exchange rate are investigated. In most cases the results are unambiguous. In particular this is true for the output and the price of local manufactures. Other conclusions are that a depreciation increases exports and the amount of services provided. In some cases unequivocal results can be obtained only with the help of further assumptions. This concerns the domestic price of rural goods, the balance of trade in domestic prices and import penetration.     

The external water footprint of the Netherlands: Geographically-explicit quantification and impact assessment

This study quantifies the external water footprint of the Netherlands by partner country and import product and assesses the impact of this footprint by contrasting the geographically-explicit water footprint with water scarcity in the different parts of the world. The total water footprint of the Netherlands is estimated to be about 2300 m³/year/cap, of which 67% relates to the consumption of agricultural goods, 31% to the consumption of industrial goods, and 2% to domestic water use. The Dutch water footprint related to the consumption of agricultural goods, is composed as follows: 46% related to livestock products; 17% oil crops and oil from oil crops; 12% coffee, tea, cocoa and tobacco; 8% cereals and beer; 6% cotton products; 5% fruits; and 6% other agricultural products. About 11% of the water footprint of the Netherlands is internal and 89% is external. Only 44% of virtual-water import relates to products consumed in the Netherlands, thus constituting the external water footprint. For agricultural products this is 40% and for industrial products this is 60%. The remaining 56% of the virtual-water import to the Netherlands is re-exported. The impact of the external water footprint of Dutch consumers is highest in countries that experience serious water scarcity. Based on indicators for water scarcity the following eight countries have been identified as most seriously affected: China; India; Spain; Turkey; Pakistan; Sudan; South Africa; and Mexico. This study shows that Dutch consumption implies the use of water resources throughout the world, with significant impacts in water-scarce regions.     

Optimal consumption and the environment Choosing between ‘clean’ and ‘dirty’ goods

In this paper, a model with heterogeneous consumption goods is presented. Consumers are assumed to choose between two different consumption goods, characterized by a different impact on the environment. This implies that, in a decentralized economy, government can sustain the social optimum by setting two Pigouvian taxes: one on production as a whole and the other on dirty consumption acting as an incentive in favour of clean consumption. In accordance with the previous literature, a trade-off between a clean environment and economic activity evolves. However, this trade-off is now mitigated by the additional taxation on polluting consumption which allows the control of pollution stock evolution through the substitution between clean and dirty commodities.     

A New Look at Old Issues: Keynesian Unemployment Revisited

Economists have long sensed that the failure of goods markets to clear is a prime reason for the emergence of unemployment. The novel feature of this paper is that it discovers a new theoretical basis proving this assumption. The paper claims that in a permanently growing economy, unemployment may be due to the failure of the markets to provide consumers with ever‐new varieties of consumption goods. As the difference between desired and available product widens, effective demand declines, leading on the one hand to unemployment, which exhibits a decisive Keynesian flavour as it is the result of goods markets failures, and on the other hand to an increase in involuntary savings, which provide the financial basis to foster innovation and growth. As the higher growth rate increases the probability of failures in effective demand, it further increases unemployment and increases involuntary savings, resulting in a finite multiplier process.     

Substitution elasticities between durable and nondurable goods in the United States: New evidence from the dynamic Laurent system

This paper uses the dynamic Laurent demand system to jointly estimate the service flows from durable and nondurable goods. The parameter estimates are used to obtain the Morishima elasticity of substitution between goods for the United States from 1960:1 to 1991:4. One of the significant results of this study is that the Morishima elasticities of substitution vary over time instead of being constant. This result implies that the use of the CES functional form gives a poor approximation of the demand system for the data used in this paper. Another important result is that consumers adjust to their long-run equilibrium holding of consumption goods slowly rather than quickly.     

International business cycles and the relative price of investment goods

Abstract Is the relative price of investment goods a good proxy for investment specific technology? We model this relative price in a flexible price international economy with two fundamental shocks, namely, the total factor productivity (TFP) shock and the investment‐specific technology (IST) shock. We show that the one‐to‐one correspondence between the IST shock and the relative price of investment goods breaks down in an international economy because of the short‐run correlation between the terms of trade and the relative price of investment goods. The data congruent negative correlation between the investment rate and the relative price of investment goods thus does not necessarily reflect decline in investment frictions (rise in IST), as suggested by many studies. A calibration experiment with the US data demonstrates that such an inverse relation between rate of investment and the relative price of investment goods basically reflects the positive effect of TFP on the terms of trade for a broad range of economies where the home bias in consumption exceeds investment and there is a sizable adjustment cost of investment.     

Modeling the migration of cultural goods: a macro-economic study of domestic Chinese cinema

This article investigates the migration of cultural goods such as movies in the burgeoning commercial exhibition marketplace of China. Based on prior research on the movie industry and theatrical releases, this empirical study models the dynamic relationships between cinema attendance and the number of cinema screens in response to consumer mindset shifts in terms of predetermined and exogenous variables. These relationships are established and estimated by applying the Vector Auto-Regression (VAR) and Seemingly Unrelated Regressions (SUR) techniques. The regression analyses are executed over 96 observations spanning from May 2005 to April 2013. A key empirical finding is that cultural goods such as movies are affected by a variety of market and economic factors. Another significant finding is that income and admission price will not significantly affect the Chinese cinema-goers’ consumption behaviors, whereas they may alter the market expectation of the exhibitors. In recent years, the prevalence of Internet options has further promoted a more competitive market of choice, quality, and prices. This is an area worthy of further scholarly investigation.     

Characteristics of mexican economic growth : Empirical testing of some latin american structuralist hypotheses

This article examines a series of hypotheses about the Latin American industrialization process put forward by the structuralist school of thought, using Mexico as a test case. In particular it examines the relationship between the distribution of income and associated patterns of consumption and industrial structure and its implications on demand-constraints, growth- constraints, employment constraint and multinational control. The results indicate that the modern-traditional dichotomy based on durable versus non-durable consumer goods is not the best way to examine this relationship since the consumption patterns for durable goods do not show a homogeneous behavior when distribution changes. Overall, it was found that growth and employment constraints and multinational control seem to get more exacerbated under greater inequality. With respect to the demand-constraints no definite conclusion can be made because of the mentioned heterogeneity in the response of durable goods to changes in distribution and the lack of information on relative excess capacity and/or dynamic linkages of the different sectors.     

Effluent taxes,market structure,and the rate and direction of endogenous technological change

This paper studies the effects of effluent taxes on firms’ allocation of resources to cost-reducing and emission-reducing R&D, and on entrepreneurs’ decisions to develop new goods and enter the market. A tax set at an exogenous rate that does not depend on the state of technology reduces growth, the level of consumption of each good, and raises the number of firms. The induced increase in the variety of goods is a benefit not considered in previous analyses. In terms of environmental benefits, the tax induces a positive rate of pollution abatement that offsets the “dirty” side of economic growth. A tax set at an endogenous rate that holds constant the tax burden per unit of output, in contrast, has ambiguous effects on growth, the scale of activity of each firm and the number of firms. Besides being novel, the potential positive growth effect of this type of effluent tax is precisely what makes this instrument effective for welfare-maximizing purposes. The socially optimal policy, in fact, requires the tax burden per unit of output to equal the marginal rate of substitution between the growth rate of consumption and abatement. Moreover, a tax/subsidy on entry is needed, depending on whether the contribution of product variety to pollution dominates consumers’ love of variety.      

相对收入与个人效用——来自中国的证据

本文考察相对收入和相对消费对人们的影响程度,并比较社会中不同收入的不平等程度是否对这种影响起作用。笔者在中国城镇居民中进行了调查实验,用特定指标衡量人们对收入和消费的相对性关注程度。实证分析发现：（1）相对收入和绝对收入对个人效用的影响始终存在,但在炫耀性消费品（如汽车和住房）和非炫耀性消费品（如假期和保险）上的影响程度不同;（2）人们对相对收入和相对消费的关注程度较为集中在同一个区间里;（3）教育程度和职业显著地影响相对收入对人们的效用,男性比女性显著地更加在意汽车和住房的相对消费;（4）社会收入不平等没有显著影响对相对收入的关注度,但对住房消费的相对性有影响。这些发现为我们了解消费行为决策和认识宏观经济中收入不平等的消费效应有一定的启示。
