The regulation of science-based claims in advertising

This paper analyzes the effects of scientific information dissemination on consumer and producer behavior. The first section draws heavily from evidence on the ready-to-eat cereal market during a period in which information developed about the health benefits of fiber cereal consumption. Although producers were initially prohibited from advertising these benefits, the regulatory ban against advertising was lifted during the period we study. Our results indicate that advertising was an important source of information leading to increased fiber cereal consumption and product innovation. The second part of our paper discusses the potential for deception if science-based claims are allowed. In the final section we consider a number of regulatory proposals that have been raised in the context of health claims for food products. We evaluate these proposals against the three goals of encouraging the dissemination of truthful information and discouraging the dissemination of deceptive or misleading information and their ability to keep pace with the changing science.     

Retail Leasing: The Determinants of Shopping Center Rents

The determinants of lease rentals are of fundamental importance to real estate researchers and practitioners. Retail leases are unique in that they typically have two rental components: a base rent and an "overage" rent equal to a percentage of the tenant's gross sales above some threshold level. In this paper, we develop and test a simple cash flow model of retail lease valuation that predicts that base rents are lower with higher percentage rent rates and are higher with greater threshold levels of sales. Using a sample of shopping center leases, regression analysis indicates that these tradeoffs are observed in the market.     

Assessing the competitive power of a region

The paper explores theoretical approaches to estimating a region’s competitiveness and its underlying factors. The competitive power indicators of the economic complex of Mogilev oblast, Belarus, are analyzed and its regional competitiveness is estimated on the basis of statistical data.     

The role of R&D in high-technology trade: An empirical analysis

Conclusion This paper attempts to establish the relationship between the level of R&D activities of a country and its trade performance in high-technology products. Empirical evidence based on the limited data used in the paper shows that this relationship appears to be quite significant. An analysis of the implications of this relationship reveals that the low level of R&D in Canada is due to, among other factors, the prevalence of foreign ownership of Canadian manufacturing industries, and the resource-based characteristic of the Canadian economy. Given the nature of foreign-owned firms, the paper suggests that countries should not rely on them as a crucial instrument in the creation of an indigenous capacity to produce high-technology products which are competitive at the world level. Instead, domestic policies aimed at the development and nurturing of the countries' own scientific and technological skills are required. The views expressed in this paper are those of the author. They should not be construed as the official views of the Ministry of State for Science and Technology of the Government of Canada.

Informed Trading Around Earnings Announcements: Another Look

This study is an empirical test of the Easley, O'Hara, and Srinivas (1998) multimarket sequential trade model of stock and option markets. We employ two approaches to determine the information content of signed stock and option trades executed around quarterly earnings announcements. The first approach expands the vector autoregression (VAR) technique of Hasbrouck (1991a) to include signed option trade volumes and inter‐trade durations. Estimates from the VAR models provide insight into whether both equity and option trades are viewed as informative by the equity specialist. The second approach focuses on the information content of the earnings releases to determine whether signed equity and option trades executed prior to the announcements are informed. Results indicate that although informed traders prefer to transact in both markets around earnings announcements, option market transactions contain no incremental information.     

Pricing Perpetual Options for Jump Processes

Abstract

We consider two models in which the logarithm of the price of an asset is a shifted compound Poisson process. Explicit results are obtained for prices and optimal exercise strategies of certain perpetual American options on the asset, in particular for the perpetual put option. In the first model in which the jumps of the asset price are upwards, the results are obtained by the martingale approach and the smooth junction condition. In the second model in which the jumps are downwards, we show that the value of the strategy corresponding to a constant option-exercise boundary satisfies a certain renewal equation. Then the optimal exercise strategy is obtained from the continuous junction condition. Furthermore, the same model can be used to price certain reset options. Finally, we show how the classical model of geometric Brownian motion can be obtained as a limit and also how it can be integrated in the two models.

Uniform and Non-Uniform Second-Best Input Taxes

We investigate second-best, input-based taxes foragricultural nonpoint pollution control when marketprices are endogenous and production isheterogeneous. Theoretically, we derive the optimalforms of taxes which take account of heterogeneity(non-uniform taxes) and a tax which does not (auniform tax). Empirically, we use a multi-factor,market-equilibrium simulation model to determineoptimal tax rates and associated equity effects,particularly differences in landowner gains/lossesacross a heterogeneous region. When market prices areendogenous, second-best tax policies result inpecuniary externalities that affect existingenvironmental externalities. In particular, thepecuniary externalities amplify the effect of producerheterogeneity on determination of sub-regionaldifferences in tax rates and returns to land,particularly for the uniform policy. With endogenousprices, the uniform tax rate is considerably higherthan any of the non-uniform rates and, ironically, thenon-uniform taxes result in less dispersion oflandowner gains across sub-regions than the uniformtax.
