The Effects of Periodic Quotas Limiting the Stock of Imports of Durables

Analyses of trade quotas typically assume that the quota restricts the flow of some nondurable good. Many real-world quotas, however, restrict the stock of durable imports. We consider the cases where (1) anyone is free to export against such quotas and where (2) only those allocated portions of the total quota are free to export against such quotas. Recent econometric investigations of such quotas have focused on the price of the durable as an indicator of tightness induced by the quota. We show why this is an inappropriate indicator and suggest alternatives.

Tests of Conditional Asset Pricing Models in the Brazilian Stock Market

In this paper, we test a version of the conditional CAPM with respect to a local market portfolio, proxied by the Brazilian stock index during the 1976-1992 period. We also test a conditional APT model by using the difference between the 30-day rate (Cdb) and the overnight rate as a second factor in addition to the market portfolio in order to capture the large inflation risk present during this period. The conditional CAPM and APT models are estimated by the Generalized Method of Moments (GMM) and tested on a set of size portfolios created from a total of 25 securities exchanged on the Brazilian markets. The inclusion of this second factor proves to be crucial for the appropriate pricing of the portfolios.

Sampling Interval and estimated Betas : Implications for the Presence of Transitory Components in Stock Prices

We provide a theoretical framework to explain the empirical finding that the estimated betas are sensitive to the sampling interval even when using continuously compounded returns. We suppose that stock prices have both permanent and transitory components. The permanent component is a standard geometric Brownian motion while the transitory component is a stationary Ornstein-Uhlenbeck process. The discrete time representation of the beta depends on the sampling interval and two components labelled \"permanent and transitory betas\". We show that if no transitory component is present in stock prices, then no sampling interval effect occurs. However, the presence of a transitory component implies that the beta is an increasing (decreasing) function of the sampling interval for more (less) risky assets. In our framework, assets are labelled risky if their \"permanent beta\" is greater than their \"transitory beta\" and vice versa for less risky assets. Simulations show that our theoretical results provide good approximations for the means and standard deviations of estimated betas in small samples. Our results can be perceived as indirect evidence for the presence of a transitory component in stock prices, as proposed by Fama and French (1988) and Poterba and Summers (1988).

Regulatory History Material as an Extrinsic Aid to Interpretation: An Empirical Study on the Use of RIAS by the Federal Court of Canada

Since 1986, the Canadian Public Administration is required to analyze the socio-economic impact of new regulatory requirements or regulatory changes. To report on its analysis, a Regulatory Impact Analysis Statement (RIAS) is produced and published in the Canada Gazette with the proposed regulation to which it pertains for notice to, and comments by, interested parties. After the allocated time for comments has elapsed, the regulation is adopted with a final version of the RIAS. Both documents are again published in the Canada Gazette. As a result, the RIAS acquires the status of an official public document of the Government of Canada and its content can be argued in courts as an extrinsic aid to the interpretation of a regulation. In this paper, an analysis of empirical findings on the uses of this interpretative tool by the Federal Court of Canada is made. A sample of decisions classified as unorthodox show that judges are making determinations on the basis of two distinct sets of arguments built from the information found in a RIAS and which the author calls “technocratic” and “democratic”. The author argues that these uses raise the general question of “What makes law possible in our contemporary legal systems”? for they underline enduring legal problems pertaining to the knowledge and the acceptance of the law by the governed. She concludes that this new interpretive trend of making technocratic and democratic uses of a RIAS in case law should be monitored closely as it may signal a greater change than foreseen, and perhaps an unwanted one, regarding the relationship between the government and the judiciary.
