Experimental Evidence of Market Reactions to New Consumption Taxes*

Abstract. Consumption taxes of various forms are of increasing importance worldwide. This study employs a laboratory market design to investigate differential market reactions to three consumption tax forms while holding all other factors constant. Ten laboratory markets were conducted, each involving nine volunteer participants. Market participants were randomly assigned to roles analogous to wholesalers, retailers, or consumers of a market good. The three tax forms were (1) a sales tax imposed on retail consumers of a commodity, (2) a gross-receipts tax imposed on retail sellers, and (3) a value-added tax imposed on sellers at two levels of production. At least three markets were conducted under each tax regime as a basis for experimental comparison. The tax rates used in each structure were chosen so that a competitive model would predict different equilibrium prices but the same tax burdens (the sum of explicit and implicit taxes) across the three tax regimes. Results generally support these predictions, with somewhat stronger support for equivalent tax revenues (explicit taxes collected) than for equivalent tax incidence (distribution of tax burdens after price adjustments). Observed tax incidence differences suggest that market agents who are called upon to explicitly pay taxes actually bear relatively lower tax burdens after implicit tax price adjustments. In general, however, price shifting is consistent with the competitive model, supporting the economic dictum that the choice among alternative designations of taxpaying agents is more a question of form than of economic substance. Résumé. Les taxes à la consommation revêtant diverses formes augmentent en importance à travers le monde. Les auteurs ont conçu un modèle de marché expérimental dans le but d'étudier les différentes réactions du marché à trois formes de taxe à la consommation, tout en maintenant constants l'ensemble des autres facteurs. Dix marchés expérimentaux ont été créés, chacun d'eux faisant intervenir neuf participants volontaires à qui étaient attribués aléatoirement des rôles analogues à ceux de grossistes, de détaillants ou de consommateurs d'un marché de produits. Les trois formes de taxe étaient les suivantes: (1) une taxe de vente s'appliquant aux consommateurs d'un bien sur le marché de détail, (2) une taxe sur les encaissements bruts s'appliquant aux détaillants et (3) une taxe sur la valeur ajoutée s'appliquant aux vendeurs, à deux échelons de production. Au moins trois marchés sous chaque régime fiscal ont servi de base de comparaison expérimentale. Les taux utilisés dans chaque structure ont été choisis de telle sorte qu'un modèle concurrentiel arrive à des prix d'équilibre différents mais à une fardeau fiscal identique (la somme des taxes explicites et implicites) sous les trois régimes. Dans l'ensemble, les résultats obtenus confirment ces prédictions, plus encore dans le cas des recettes fiscales équivalentes. Les différentes incidences fiscales observées donnent à penser que les agents du marché de qui l'on réclame explicitement des taxes supportent, en réalité, un fardeau fiscal relativement moins élevé, une fois opérés les ajustements de prix relatifs aux taxes implicites. De manière générale, cependant, les variations de prix sont conformes au modèle concurrentiel, ce qui corrobore cet axiome économique selon lequel le choix des agents à qui doit être attribué le rôle de contribuable est davantage une question de forme que de substance économique.     

Testing Volatility Restrictions on Intertemporal Marginal Rates of Substitution Implied by Euler Equations and Asset Returns

The Euler equations derived from intertemporal asset pricing models, together with the unconditional moments of asset returns, imply a lower bound on the volatility of the intertemporal marginal rate of substitution. This paper develops and implements statistical tests of these lower bound restrictions. While the availability of short time series of consumption data often undermines the ability of these tests to discriminate among different utility functions, we find that the restrictions implied by a number of widely studied financial data sets continue to pose quite a challenge to the current generation of intertemporal asset pricing theories.     

The Take‐Up of Multiple Means‐Tested Benefits by British Pensioners: Evidence from the Family Resources Survey

Non‐take‐up of means‐tested benefits among pensioners is of long‐standing concern. It has assumed increased importance from October 2003 with the introduction of the new means‐tested pension credit to which about half of pensioners are expected to be entitled. We use Family Resources Survey data from April 1997 to March 2000 to investigate patterns of pensioner take‐up of income support (IS) (subsequently renamed the minimum income guarantee and now subsumed in pension credit), housing benefit (HB) and council tax benefit (CTB). Although 36 per cent of pensioners in our sample failed to claim their entitlements to at least one of these benefits, only 16 per cent failed to claim amounts worth more than 10 per cent of their disposable income. Generally, take‐up is high where entitlement is high. But there are exceptions which may reflect the claims process and/or a greater degree of social stigma associated with IS than with HB or CTB.     

Market Preemption and Entry Deterrence: Evidence from the Golf Course Industry

The population in a given geographical area has to be large enough before the area can support the entry of a golf course. The required amount of population will be higher if costs are higher, or if the underlying demand to golf by residents is lower, or if there is more preexisting competition from incumbent golf courses. If incumbent golf courses undertake entry‐deterring strategies, either explicitly or implicitly, the required population will be higher still. If population is expected to grow quickly, then the amount of population required by the entry date could be lower. These effects are measured and analyzed in this empirical study of the entry of 104 golf courses in the greater San Francisco Bay Area between 1893 and 2001.     

Privatization and Reformation*

This paper presents a simple model of a government contemplating the pre-sale reform of a public enterprise. While the government is less efficient at such reform than the eventual owner, failure to reform may be considered an indicator of low commercial value by potential purchasers. Consequently, the government may be unable to avoid socially wasteful restructuring if it wishes to maximize its net sales revenue. The results presented in this paper provide a number of insights and policy recommendations for governments embarking on a privatization program.     

WILLINGNESS TO PAY FOR AIR QUALITY: THE CASE OF OUTDOOR EXERCISE

This study uses a contingent valuation (CV) survey to establish a sample of outdoor exercisers' willingness to pay (WTP) for ambient air quality improvements in East Baton Rouge parish, Louisiana. Estimated annual median and mean WTP values are £95 and £191, respectively, per person per year for assurance that ozone levels would not become "unhealthful" on any day. The survey informed respondents that in the prior year the local community experienced 14 days on which ozone levels exceeded federal standards. The study makes the strong assumptions that respondents believed they were "buying" 14 more healthy days and that WTP per day "bought" is constant. Given these assumptions, one can scale this WTP response to represent annual medians and means of approximately £7 and £14 per person per day, respectively. An econometric procedure for generalizing the community's annual WTP to avoid the 14 unhealthful days yields estimates ranging from £3.21 and £5.36 per person per healthy day, or between £12.4 and £20.6 million per year. The unit day estimates are comparable to CV and household production finction estimates of WTP in the Los Angeles basin, suggesting their usefulness for benefits transfer .
