ESTIMATING IMPORT AND EXPORT DEMAND ELASTICITIES FOR MAURITIUS AND SOUTH AFRICA

In this paper, we re‐estimate the import and the export demand functions for Mauritius and South Africa using time series data. We use the bounds tests for cointegration and find evidence of a long‐run relationship between import demand, income and prices for both countries. Our long run elasticities reveal that domestic income and relative prices have significant effects on the import demand for both countries, with income being the most important determinant. Furthermore, we find that while South Africa's export demand is not responsive to relative prices or income; for Mauritius income is statistically significant.     

VACCINE HESITANCY,PASSPORTS, AND THE DEMAND FOR VACCINATION

Vaccine hesitancy is modeled as an endogenous decision within a behavioral epidemiological model with endogenous agent activity. It is shown that policy interventions that directly target costs associated with vaccine adoption may counter vaccine hesitancy whereas those that manipulate the utility of unvaccinated agents will either lead to the same or lower rates of vaccine adoption. This latter effect arises with vaccine passports whose effects are mitigated in equilibrium by reductions in viral/disease prevalence that themselves reduce the demand for vaccination.     

INFORMATION AND THE DEMAND FOR CLEAN AIR

This paper examines the relationship between the relocating household's reaction to air quality and its information on environmental quality. The results suggest households exposed to public information on the environment are more responsive to air quality differences if they also are knowledgeable about local environmental conditions.

REVENUE, PROGRESSIVITY, AND THE FLAT TAX

This paper uses detailed household data to analyze revenue potential and progressivity under two popular "flat tax" proposals. The results show that the Hall and Rabushka version of the flat tax would generate $626 billion in revenue in 1993 while the more generous plan of Armey and Shelby would produce only $538 billion. Integrating the individual tax with the business tax indicates that both proposals are progressive. However, there is a substantial shift of the tax burden from the highest income classes to the middle classes in comparison to the current system.     

FINANCIAL INNOVATION AND THE DEMAND FOR MONEY: EVIDENCE FROM THE PHILIPPINES

This paper tests whether financial innovations in the Philippines distorted the long-run relation between real money balances, income and interest rates. Using data for the monetary base, M1 and M3 over the period 1980–1998, we cannot reject the hypothesis that there does not exist a standard money demand relation between M1 and M3, real income and interest rates. However, when we allow for the impact of financial innovations, this finding is reversed for M1. Estimates of ECM models for these measures also show that financial innovations impacted real money balances for M1, but not M3. This evidence supports the Philippine central bank's choice of a monetary aggregate as its policy instrument to achieve its policy objectives. [E41, E58]     

SOCIAL INTERACTIONS AND THE DEMAND FOR SPORT: AN ECONOMIC ANALYSIS

This paper explores the decision to participate in sports activities in the United Kingdom and the subsequent frequency of participation. The paper draws links between economic and other theories of social interaction to motivate the discussion and links these theories to assessing policy initiatives in the United Kingdom. Cluster analysis is combined with a Heckman analysis to examine the empirical evidence provided by the General Household Survey in 2002. The results suggest that social and personal capital are of paramount importance in determining sports participation, and consequently, it is these features that policy should focus upon. However, the legitimacy of policy activism requires philosophical justification. ( JEL B41, C2, D11, D12)     

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.     

ECONOMIC UNCERTAINTY,MONETARY UNCERTAINTY AND THE DEMAND FOR MONEY IN AUSTRALIA

The demand for money and its stability in Australia has received a great deal of attention in the past and has resulted in its own literature. Depending upon estimation method and period of analysis, previous research has provided mixed findings. By including a measure of economic uncertainty and a measure of monetary uncertainty (both GARCH‐based) in the long‐run money demand for M3, and by using the bounds testing approach under which variables could be stationary or non‐stationary, we provide strong evidence that the M3 money demand in Australia is stable. Both uncertainty measures do have short‐run as well as long‐run effects on the demand for M3 in Australia, factors that previous research did not consider.     

THE DEMAND FOR BEVERAGES AND INTERBEVERAGE SUBSTITUTION IN THE UNITED STATES

The analysis in this paper is directed at measuring the substitution between seven beverages consumed in the United States with the objective of shedding some light on just what is the relevant market for antitrust purposes. With regard to the overall beverage market considerations, there is a clear indication that consumers do substitute between different types of beverages. What must be subjectively resolved, however, is whether the extent of the indicated substitution is of significant enough magnitude to infer that two different beverages are in the same product market.
