In both economic and military situations, agents may try to mislead rivals about their true types or plans, whatever they may be. We consider a simple model in which one player attacks and the other player defends. We show that such environments have two types of possible equilibrium behavior, depending upon the signaling technology. If the signal is not very revealing about the attacker's plans, then the attacker always invests more resources in attack than in misdirection. If the technology is revealing, then the attacker does not always feint, but when he feints, he invests more than half of his resources into misdirection. Comparative statics also depend on whether the technology is revealing.

This paper analyzes the factors that have influenced the supply and demand for teacher quality in Arkansas' public schools. The paper relies on results from a basic skills test, given to all Arkansas public school teachers in 1985, to measure teacher quality. Relying on these data, a simultaneous equation model is constructed to disentangle the supply and demand forces that determined the level of teacher quality in a county. Price and income elasticities are also calculated and compared to elasticity estimates found in other studies.  相似文献

In contrast to earlier studies using adult subjects, this experiment with first graders did not f’md a high degree of brand loyalty development in response to a minimally differentiated product. In fact, while some brand preferences did develop, most subjects appeared to seek some degree of variety in their choices. It is interesting to speculate that children have a “greater need for novelty” than adults and are thus less likely to develop brand loyalty. However, extensive research will be required to remove this proposition from the realm of speculation.  相似文献

Previous studies on home country effects mainly focused on FDI from large developed economies to other countries. But today's super recipient is a relatively larger economy than its investors and many of these investors are not classified as “developed economies.” A simple Ak type model implies that a small and more developed country investing in a large and less developed country will experience decreases in both employment and income disparity (compared to the recipient country) as the less-developed recipient country gains the higher technology of production through FDI inflows. The empirical results for the Four Tigers (source countries) and China (recipient country) are consistent with our theoretical model of FDI outflows. We also find that FDI outflows to China decrease the ratio of exports to GDP only for small source countries, even though a higher investment in China raises the share of these countries' exports-to-China to China's total imports.  相似文献

In previous periods when agricultural production was large relative to demand in North America, supply control through limitations in production and markets has been used. Large cropfalls and mammoth international purchases by the USSR during the early 1970s depleted North American grain stocks and caused major supply control programs to vanish. With more favorable worldwide weather, however, grain production and carryover have increased to levels where farmers may demand supply and market controls to improve prices and income. In contrast to conventional models, we make a quantitative analysis for the United States to three tax policies which might be used to restrain production and improve prices and farm income. All tax alternatives do so if the taxes collected by the government are returned to farmers. The tax alternatives examined include a tax on inputs, a gross sales tax, and a tax-in-kind similar to a share rent. The tax policies are applied through an econometric simulation model. Certain limitations of the tax policies are explained. Aux époques antérieures, lorsque la production agricole était grande compareée à la demande dans l'Amérique du Nord, on a contrôlé les stocks de réserve par moyen de limitations de production et de vente. Les récoltes inférieures et les énormes achats par l'URSS pendant la premiére partie des années 70 ont diminué les réserves des céréales de l'Amérique du Nord, ce qui a rendu superflus les programmes majeurs de contrôle. Toutefois, un climat global favorable a augmenté la production et l'accumulation jusqu'au point oú les agriculteurs peuvent considérer nécessaires des contrôles sur la production et la vente afin d'améliorer les prix et leurs revenus. Faisant contraste avec les modéles conventionnels, nous présentons une analyse quantitative pour les Etats-Unis de trois systémes d'impôts qui pourraient etre appliqués pour diminuer la production et pour améliorer les prix et les revenus agricoles. Tous les trois systémes sont effectifs à ce but, pourvu que les impôts perçus par le gouvernement soient rendus aux producteurs. Les alternatifs examinés comprennent un impôt sur les frais de production, un impôt en gros sur les ventes et un systéme d'impôts payables par une quantité des céréales produites, semblable au métayage. Les systémes sont appliqués par moyen d'un modéle de simulation économétrique. Certaines limitations des systémes sont presentées.  相似文献

This article develops and empirically implements an arbitrage-free,dynamic term structure model with "priced" factor and regime-shiftrisks. The risk factors are assumed to follow a discrete-timeGaussian process, and regime shifts are governed by a discrete-timeMarkov process with state-dependent transition probabilities.This model gives closed-form solutions for zero-coupon bondprices, an analytic representation of the likelihood functionfor bond yields, and a natural decomposition of expected excessreturns to components corresponding to regime-shift and factorrisks. Using monthly data on U.S. Treasury zero-coupon bondyields, we show a critical role of priced, state-dependent regime-shiftrisks in capturing the time variations in expected excess returns,and document notable differences in the behaviors of the factorrisk component of the expected returns across high and low volatilityregimes. Additionally, the state dependence of the regime-switchingprobabilities is shown to capture an interesting asymmetry inthe cyclical behavior of interest rates. The shapes of the termstructure of volatility of bond yield changes are also verydifferent across regimes, with the well-known hump being largelya low-volatility regime phenomenon.  相似文献

Qualitative audit materiality and earnings management   总被引:2,自引:0,他引:2  
This study investigates auditors’ propensity to rely on quantitative materiality thresholds to the exclusion of qualitative materiality thresholds. Specifically, we examine whether auditors are more likely to allow earnings management that is less than typical quantitative materiality thresholds but that nonetheless is qualitatively material. We use changes in tax expense as a proxy for earnings management. Our results indicate that companies with pre-managed earnings that would have missed the consensus analyst forecast are more likely to decrease their tax expense when the magnitude of the decrease is less than quantitative audit materiality thresholds. The results also indicate that firms are more likely to meet or beat the forecast when the amount of earnings management necessary to meet the analyst forecast is less than quantitative materiality. These results are consistent with auditors relying on quantitative materiality thresholds to the exclusion of qualitative materiality thresholds, i.e., the importance of meeting or beating the analyst forecast. Finally, we find that the ability to use tax expense reduction within quantitative materiality to meet or beat analysts’ consensus forecasts was significantly reduced by the SEC’s guidance on materiality in SAB-99 and by the passage of the Sarbanes–Oxley Act.  相似文献
