Jon P. Nelson 《Review of Industrial Organization》2003,22(1):1-25
Using a panel of 45 states for the period 1982–1997,this study analyzes the importance of severalrestrictive alcohol regulations, including advertising bans for billboards, bans of price advertising, state monopoly control of retail stores, and changes in the minimum legal drinking age. In contrast to previous research, the study allows for substitution among beverages as a response to a regulation that targets a specific beverage. A restrictive law that applies only to one beverage (or one form of advertising) can result in substitution toward other beverages (or non-banned media). Allowing for substitution means that the net effect on total alcohol consumption is uncertain, and must be determined empirically. The empirical results demonstrate that monopoly control of spirits reduces consumption of that beverage, and increases consumption of wine. The effect on beer is positive, but is not statistically significant. The net effect on total alcohol is significantly negative. Higher minimum legal drinking age laws have negative effects on beverage and total alcohol consumption. Bans of advertising do not reduce total alcohol consumption, which partly reflects substitution effects. The study thus demonstrates the possible unintended consequences of restrictive alcohol regulations. 相似文献

Monetary policy for an open economy: an alternative framework with optimizing agents and sticky prices 总被引:5,自引:0,他引:5
The 'new open-economy macroeconomics' seeks to provide an improvedbias for monetary and exchange-rate policy through the constructionof open-economy models that feature rational expectations, optimizingagents, and slowly adjusting prices of goods. This paper promotesan alternative approach for constructing such models by treatingimports not as finished consumer goods but rather as raw-materialinputs to the home economy's productive process. This treatmentleads to a clean and simple theoretical structure that has someempirical attractions as well. A particular small-economy modelis calibrated and its properties exhibited, primarily by meansof impulse response functions. The preferred variant is shownto feature a pattern of correlations between exchange-rate changesand inflation that is more realistic than provided by a morestandard specification. Important recent events are interpretedin light of the alternative models. 相似文献

A binomial approximation to a diffusion is defined as 'computationallysimple' if the number of nodes grows at most linearly in thenumber of time intervals. It is shown how to construct computationallysimple binomial processes that converge weakly to commonly employeddiffusions in financial models. The convergence of the sequenceof bond and European option prices from these processes to thecorresponding values in the diffusion limit is also demonstrated.Numerical examples from the constant elasticity of variancestock price and the Cox, Ingersoll, and Ross (1985) discountbond price are provided. 相似文献

Dynamic Seemingly Unrelated Cointegrating Regressions 总被引:4,自引:0,他引:4
We propose the parametric Dynamic Seemingly Unrelated Regression (DSUR) estimator for simultaneous estimation of multiple cointegrating regressions. DSUR is efficient when the equilibrium errors are correlated across equations and is applicable for panel cointegration estimation in environments where the cross section is small relative to the available time series. We study the asymptotic and small sample properties of the DSUR estimator for both heterogeneous and homogeneous cointegrating vectors. We then apply the method to analyse two long-standing problems in international economics. Our first application revisits the estimation of long-run correlations between national investment and national saving. Our second application revisits the question of whether the forward exchange rate is an unbiased predictor of the future spot rate. 相似文献

The purpose of this research was to examine empirically the effects of new product development outcomes on overall firm performance. To do so, first product development and finance literature were connected to develop three testable hypotheses. Next, an event study was conducted in order to explore whether the changes in the stock market valuation of firms are influenced by the outcomes of efforts to develop new products. The pharmaceutical industry was chosen as the empirical context for the present study's analysis largely because the gate‐keeping role played by the Food and Drug Administration (FDA) provides a specific event date on which to focus the event study methodology. As such, this study's events were dates of public announcements of the FDA decisions to approve or to reject the New Drug Applications submitted by the sponsoring firms. Consistent with the efficient market hypothesis, this study's results show that market valuations are responsive strongly and cleanly to the success or failure of new product development efforts. Hence, one of this study's key results suggests that financial markets may be attuned sharply to product development outcomes in publicly traded firms. This study also finds that financial market losses from product development failures were much larger in magnitude than financial market gains from product development successes—indicating an asymmetry in the response of financial markets to the success and failure of new product development efforts. Hence, another implication of this study's results is that managers should factor in a substantial risk premium when considering substantial new development projects. The present study's results also imply that managers should refrain from hyping new products and perhaps even should restrain the enthusiasm that the financial community may build before the product fully is developed. The effect on firm value is severe when expectations about an anticipated new product are not fulfilled. Managers in effect should take care to build reasonable and realistic expectations about potential new products. 相似文献

A comparison of ranking,rating and reservation price measurement in conjoint analysis 总被引:2,自引:1,他引:1
This paper empirically compares the traditional preference measures of ranking and rating in conjoint analysis with a direct monetary measure of product value — reservation prices. Experimental results are as expected. While reservation prices do very well in terms of fit, they are inferior in terms of predicting choice on a holdout sample. In addition, surprisingly little difference is found in the performance of ranks and ratings. 相似文献
