Rationally addicted to drinking and smoking?

When modelling demand for addictive consumption goods, the most widely used framework is the rational addiction model proposed by Becker and Murphy. This paper extends the rational addiction model to include two addictive consumption goods, alcohol and cigarettes, and using aggregate annual time series on sales volumes for the period 1955–1999, estimates the aggregate demand for these goods in Sweden, where OLS estimates are compared to GMM estimates allowing for possible endogeneity of lagged and lead consumption. First, the demand for alcohol and cigarettes are estimated as separate equations and it is found that alcohol demand is quite well described by the rational addiction model while the same is not true for cigarettes. The own-price elasticities are negative, and alcohol demand is more elastic than cigarette demand. The cross-price elasticities are also negative, showing that alcohol and cigarettes are complements. Since consumption of alcohol and cigarettes are probably simultaneous decisions, the demand for these goods is estimated as a system of equations and it is found that alcohol demand is still positively affected by lagged and lead consumption while cigarette demand is not. It is also found that the elasticities obtained are now generally smaller compared to when estimating the equations separately.     

Kalman filter and the demand for cigarettes

kalman filter estimates of price, income and advertising elasticities are presented. An analysis of structural change in the demand for cigarettes in the US for the period 1929–86 is made. Estimated price and income elasticities are generally smaller, and the advertising elasticity larger, than estimates previously found. Cigarette demand is inelastic with respect to price and income, and advertising elasticity is statistically insignificant for the most part. Furthermore, both income and price elasticities decline over time while advertising elasticity tends to rise. Four time periods where structural change has occurred are identified. The health scare reports and the Fairness Doctrine Act have a significant impact on per capita cigarette consumption.     

A censored system of cigarette and alcohol consumption

Many previous studies of US cigarette and alcohol consumption have focused on single equations. However, the addictive nature of consumption suggests that it is more appropriate to model these products as a system. We propose a two-step estimation procedure and apply the procedure to a system of equations for cigarette, beer and wine consumption. Results differ from those derived from an existing two-step procedure. Findings suggest that consumption of cigarettes, beer and wine is responsive to income changes but the elasticities are rather small. Personal physiques, education, age, race, ethnicity, health, gender, employment status, and regions also play significant roles in consumption.     

Exports to Smuggle and Smuggling Technologies*

Our analysis is motivated by cases of cigarette smuggling in Canada and in the UK. In the 1990s, domestic cigarettes were legally exported to be subsequently illegally imported. At first, smuggling was done by individual consumers who bought cigarettes abroad and brought them back through policed points of entry. This Mom and Pop smuggling was a mechanism to implement a second‐degree price discrimination scheme by cigarette manufacturers. Regrets from committing tax evasion and labels on exported cigarettes packs permit vertical differentiation of illegal and legal cigarettes. Paradoxically, labeling measures can make illegal sales more resilient to tax reductions, and stricter border enforcement encourages a switch to a less benign smuggling technology exclusive to criminal organizations. High export taxes terminated export‐to‐smuggle schemes, but brought about a surge of counterfeit cigarettes. Because of a second‐degree price discrimination scheme, the elimination of taxes need not suffice to eradicate smuggling.     

How Elastic is East Asian Demand for Consumption Goods?

This paper investigates import demand in East Asia. Estimating exchange rate elasticities for countries in the region is difficult because many imports are used to produce goods for re‐export. An exchange rate appreciation that reduces East Asian exports will also reduce the demand for imported inputs that are used to produce exports. To correct for this bias this paper examines consumption imports, since these goods are intended primarily for the domestic market. Results from several specifications indicate that currency appreciations and increases in income in East Asian countries would significantly increase imports into the region.     

Estimation of Armington elasticities in a CGE economy-energy-environment model for Europe

The main goal of the article is to estimate Armington elasticities of the energy and energy-intensive sectors of the GEM-E3 computable general equilibrium model. The model follows the standard two-stage budget optimisation of the consumer by first optimising between domestically produced and imported goods and, then, by country of origin. A panel data econometric framework is used here with dynamic adjustment to capture both the long and short term elasticities for the studied six aggregated sectors in Europe. The estimated long-term elasticities are in line with the literature, but higher than those used in the GEM-E3 model. The results suggest that consumer choice appears to be more price sensitive between the domestic and the composite imported goods, and amongst the importers, than already assumed in the model.     

Cigarette demand and tax policy for race groups in South Africa

This paper calculates cigarette demand for race groups in South Africa. Elasticities are the most important information a tax policy analyst can have. Elasticities determine how the tax base will change with a change in the tax rate and thus how government revenues will respond to the tax. Elasticities also determine the excess burden that consumers will bear as a result of the tax. As such, own price, crossprice, and expenditure elasticities are calculated along with government revenue maximizing tax rates, and total and excess burdens. Parametric and semiparametric estimation techniques are used and compared. Results show that a tax on cigarettes will discourage nonsmokers from starting to smoke and mainly raise revenue from current smokers. Furthermore, it is found that consumption behaviours between groups are different implying different government revenue maximizing tax rates for each group affecting the distribution of income.     

The Gradual Response of Cigarette Demand to Health Information

The paper focuses on the US cigarette industry and uses a gradual switching regression model to estimate changes in the US demand for cigarettes over time. This technique is found to be superior to the use of dummy variables in capturing the health scare. The results show that cigarette demand gradually decreased over a ten‐year period coinciding with the release of key health information. Price and advertising elasticities have gradually diminished, which is consistent with a change in the mix of US consumers before and after the switch.     

The Italian Automotive Industry and Economies of Scale

This article investigates scale economies in the Italian automobile industry as well as substitution possibilities between inputs and direct and cross-price elasticities of factor demand, utilizing a cost function with capital, labor, domestic, and imported intermediate goods inputs. Continuing European integration makes economies of scale an important issue. The study results are consistent with economies of scale in the Italian motor vehicle industry, a particularly interesting finding because the Italian automotive industry consists primarily of one firm, Fiat. The estimated direct price elasticities suggest that capital is most responsive to own price changes, and estimated cross elasticities imply that all inputs are substitutes. (JEL D 2, L 6, O 1)     

European Integration and Production in the French Economy

Effects of greater European integration on the French economy are explored with an aggregate cost function. Input direct price elasticities are inelastic, but greatest (absolute value) for capital and lowest for imports. Cross-price elasticities suggest inputs are substitutes and are higher for domestic inputs than domestic input and imports pairs. As trade restrictions fall, effects on domestic input demand may increase as substitution elasticities rise. Inverse output supply price elasticities indicate domestic input prices are relatively important factors affecting consumption goods prices and import prices more important for investment goods. Thus, import price decreases may stimulate investment and growth. (JEL F14 , O10 , O12 )     

CLEAN INDOOR AIR LAWS AND THE DEMAND FOR CIGARETTES

This paper empirically tests the effect of clean indoor air laws on smoking. Public place clean indoor air laws restrict cigarette smoking in public places such as restaurants. Private place clean air laws regulate smoking in private work places as well as in public places. This study uses a time series of cross sections of the 50 states of the United States and Washington, D.C., from 1975 through 1985, to estimate single equation and simultaneous equation models of cigarette demand. The single equation results indicate that both the public place law and the private work place law have a negative effect on cigarette demand. However, a test for endogeneity shows that the enactment of clean indoor air laws is a function of cigarette demand. Results from a simultaneous equations model indicate that the public place law has a significant negative impact on cigarette demand, while the work place law has no effect on cigarette demand. Although these results demonstrate that only states with low levels of smoking have passed work place clean air laws, the results do not imply that the level of smoking would not decrease if such a law were imposed in all states.     

Intertemporal substitution in import demand and the role of habit formation: an application of Euler equation approach for Pakistan

Introduction

The study examines the importance of intertemporal substitution in import demand considering the role of habit formation. A two-goods version of the permanent income model is used in which time-non-separability in consumers’s preferences is assumed. The model is estimated using annual data for Pakistan at disaggregated level covering the period from 1977 to 2017.

Objectives

The objective of the study is to estimate elasticities of substitution along with parameters of habit formation for consumption goods at a disaggregated level.

Method

The study employs co-integration for the estimation of parameters of elasticities of substitution and generalized method of moments (GMM) for the estimation of the parameters of habit formation from Euler equations.

Findings

The estimates of intertempral elasticity of substitution suggest that the nature of commodity group (necessity/luxury) plays an important role when consumers are making intertemporal choices. Moreover, the study finds that intratemporal elasticity of substitution is larger than intertempral elasticity of substitution in almost all cases in Pakistan, suggesting that imported and domestic goods are best described as substitutes in Edgeworth-Pareto sense. In addition, the inclusion of habit formation delivers results with plausible signs and the habit formation process seems significant for certain commodity groups including tea, beverages, tobacco products and drugs.

Conclusion

The study concludes that there is a possibility of crowding out effect on domestic consumption and the depreciation of local currency may improve Pakistan’s balance of trade.

     

Advertising bans, tobacco and cigarette consumption

Advertising of tobacco and cigarettes in the electronic media has been banned in Australia since 1976. Apart from a short-lived initial impact we find that it has not affected cigarette demand but does appear to have had some impact on tobacco consumption.     

A Cost Function Analysis of the Australian Transportation Equipment Industry

This article investigates the existence of economies of scale and input cross and direct price elasticities of demand in the Australian motor vehicle industry. Our estimated cost elasticities were less than one (consistent with economies of scale), but not significantly less than one at the 10 per cent level for two versions of the model. However, the estimated cost elasticity was significantly less than one at approximately the 2.5 per cent level for a third. Thus, these results give some credibility to the infant industry argument for continued assistance to the Australian transportation equipment industry. A four-input model separating domestic and foreign intermediate goods inputs suggests that while restrictions on imported components may have given some short-run relief to the domestic components industry and increased the demand for labour domestically, they decreased the demand for domestic capital. Although the infant industry argument could support short-run protectionist policies for the industry, it appears that such policies regarding the Australian motor vehicle industry must be designed carefully with a specified phase-out period if long-term adverse results are to be avoided.     

Export demand elasticities and productivity as determinants of growth: estimates for Mauritius

In this article, we combine the export led and import led growth hypotheses in a growth model in which the importation of foreign capital goods and the demand elasticities of own export products explain the growth opportunities and the technical progress of developing countries. This model, based on imported capital goods, uses Mauritius’ data on capital investment, employment, export partners’ growth and terms of trade to estimate price and income elasticities of export demand, total factor productivity growth and economies of scale. These elasticities are then used to assess how the growth in export partners’ income is converted into domestic growth. The implications of the presence of low or high export demand elasticities are discussed by relating them to various strands of trade and growth literature. Based on the results of this estimation, we also calculate steady state growth rates, engine and handmaiden effects of growth as well as the dynamic steady state gains from trade for this latecomer export economy. The implications of steady state results are also discussed in the light of the Mauritian employment and growth perspectives.     

International outsourcing and the demand for skills

This paper explores the impact of international outsourcing on the demand for skills in three small and open EU economies. A model of variable costs and factor demand functions for different skill levels and imported as well as domestic materials are constructed. International outsourcing is treated directly as a substitution process between labour of different skills and imported inputs. The direct consequence of international outsourcing for labour is measured by the cross price elasticities. These cross price elasticities indicate a negative outsourcing impact on low- and medium-skilled labour in the three countries and on high-skilled labour in two out of the three countries. This outsourcing effect on labour is compared with the direct effect of embodied technical change and of the technical change bias. International outsourcing has a more unambigous and significant negative impact on labour than technical change. Technical change is either labour using (embodied technical change) or only slightly biased in favour of high-skilled labour. When the cost savings effect of international outsourcing is taken into account, an indirect positive stimulus for all skill categories arises from a greater demand for goods. It can be shown, that this indirect positive effect can compensate for a large part of the negative substitution impact of international outsourcing on labour.     

Advertising and Restrictions in the Cigarette Industry: Evidence of State-by-State Variation

Many studies estimate the relationship between advertising and consumption in the cigarette industry, with emphasis directed toward the national demand for cigarettes. However, in light of evidence that cigarette producers price discriminate across U.S. states, coupled with possible affects of advertising on market power, this article takes a less aggregate perspective by addressing the role of cigarette advertising and restrictions at the state level. The results show that although advertising has little effect on demand, it generally increases market power in the cigarette industry (particularly during periods of heightened advertising restrictions). Furthermore, the relationship between advertising, demand, and supply vary across states. (JEL L13 , L66 , I18 )     

The US National Tobacco Settlement: the effects of advertising and price changes on cigarette consumption

This paper provides an econometric analysis of the effects of cigarette price and advertising changes stemming from the United States Tobacco Settlement of 1998. This is done by estimation of a demand function for cigarettes, based on data from both before and after the Settlement. The model is estimated using monthly time series data for the period 1990–2000. Results show that the increase in cigarette prices stemming from the Settlement reduced per capita cigarette consumption in the USA by 8.3%. However, the cigarette companies also increased advertising in the years immediately preceding and following the Settlement. This study estimates that this increased advertising partially offsets the effects of the higher prices, increasing cigarette consumption by 2.7 to 4.7%, and hence blunting the effects of the price increase by 33–57%.     

Cigarette tax revenues and tobacco control in Japan

The hypotheses of non-addiction, myopia and rational addiction are tested using annual, quarterly and monthly data. Changes in the prices of Japanese cigarettes can be viewed as exogenous from the point of view of consumer behaviour, because the Japanese government controls cigarette prices. The empirical results of this paper support the addiction hypothesis. The short-run and long-run price elasticities range from ?0.338 to ?0.421, and from ?0.679 to ?0.686, respectively; thus, increases in tax revenues in the long run are likely to be smaller than those in the short run. As a result, tax increases would be an effective means of curbing smoking and reducing its social cost. Furthermore, the debt compensation programmes for the Japan Railway and the National Forestry will not go according to plan, unless revenues are increased in the future.     

Is Local Food More Environmentally Friendly? The GHG Emissions Impacts of Consuming Imported versus Domestically Produced Food

With the increased interest in the ‘carbon footprint’ of global economic activities, civil society, governments and the private sector are calling into question the wisdom of transporting food products across continents instead of consuming locally produced food. While the proposition that local consumption will reduce one’s carbon footprint may seem obvious at first glance, this conclusion is not at all clear when one considers that the economic emissions intensity of food production varies widely across regions. In this paper we concentrate on the tradeoff between production and transport emissions reductions by testing the following hypothesis: Substitution of domestic for imported food will reduce the direct and indirect Greenhouse Gas (GHG) emissions associated with consumption. We focus on ruminant livestock since it has the highest emissions intensity across food sectors, but we also consider other food products as well, and alternately perturb the mix of domestic and imported food products by a marginal (equal) amount. We then compare the emissions associated with each of these consumption changes in order to compute a marginal emissions intensity of local food consumption, by country and product. The variations in regional ruminant emissions intensities have profound implications for the food miles debate. While shifting consumption patterns in wealthy countries from imported to domestic livestock products reduces GHG emissions associated with international trade and transport activity, we find that these transport emissions reductions are swamped by changes in global emissions due to differences in GHG emissions intensities of production. Therefore, diverting consumption to local goods only reduces global emissions when undertaken in regions with relatively low emissions intensities. For non-ruminant products, the story is more nuanced. Transport costs are more important in the case of dairy products and vegetable oils. Overall, domestic emissions intensities are the dominant part of the food miles story in about 90 % of the country/commodity cases examined here.
