The two-country monetary model is extended to include a consumption externality with habit persistence. The model is simulated using the artificial economy methodology. The ‘puzzles’ in the forward market are re-examined. The model is able to account for: (a) the low volatility of the forward discount; (b) the higher volatility of expected forward speculative profit; (c) the even higher volatility of the spot return; (d) the persistence in the forward discount; (e) the martingale behavior of spot exchange rates; and (f) the negative covariance between the expected spot return and expected forward speculative profit. It is unable to account for the forward market bias because the volatility of the expected spot return is too large relative to the volatility of the expected forward speculative profit.  相似文献

Either anticipated or unanticipated money affects output in fourteen of twenty U.S. manufacturing industries. In most of these instances, however, Akaike's final prediction error criterion indicates that money enters an industry's output equation with lags of three months or less. For just two industries, tobacco manufacturing and textile mill products, are there clear indications that money is not neutral at extended lags. Each of these industries is concentrated in one or two states suggesting that monetary policy may affect output through a regional credit channel.  相似文献

This paper presents the results of a study of the effect of a business ethics course in enhancing the ability of students to recognize ethical issues. The findings show that compared to students who do not complete such a course, students enrolled in a business ethics course experience substantial improvement in that ability.  相似文献

Irrigated rice farming in Costa Rica involves use of agrochemicals that pollute important wetlands ecosystems, such as the Palo Verde National Park in the northeastern province of Guanacaste. We characterize rice farming in this region, apply duality theory to estimate conditional factor demand for fertilizer, and then simulate the impacts of alternative policies on fertilizer use. Using a normalized profit function, we also estimate policy impacts on farmer profits. As expected, prices of rice seeds and fertilizer significantly affect use of fertilizer. Price incentives or taxes could encourage farming practices that reduce the threat to downstream ecosystems.  相似文献

This paper analyzes the impact of hurricanes on insurance stock returns in the United States. The objective is to assess the reaction of insurance stock prices caused by hurricanes using an extensive data sample consisting of the costliest hurricanes since 2004. We aim to understand the insurance stock price reactions and provide possible explanations for the observed results. The main outcome is a negative abnormal return for all examined time windows. Analyses of impact factors show that high-category hurricanes have more negative abnormal returns in comparison to low-category hurricanes. The latter category is even positively correlated with the cumulative abnormal return. The regression model indicates a statistically significant negative correlation between the cumulative abnormal return and the damage caused by the hurricane.  相似文献

We examine whether venture capital (VC) investment enhances corporate innovation in Korea. Using a matched sample of 802 firms from 1998 to 2012, we find that after the first round of VC investment, VC-backed firms are more innovative than non-VC-backed firms. Our results suggest that the positive influence of VC investment largely comes from the ability of VC firms to reduce information asymmetry between investors and ventures: VC funds managed by independent venture capitalists significantly enhance corporate innovation, whereas those managed by governmental venture capitalists do not. Furthermore, this positive influence becomes more pronounced where there is greater information asymmetry. Finally, we show that funds with profit-based compensation structures are more likely to encourage corporate innovation than those with fee-based compensation structures.  相似文献

The current research examined how the perceived physical attractiveness (by humans) of an endangered species, the Dead Leaf Butterfly (Kallima inachus), political orientation, and political ideology impacted participants' attitudes toward supporting and protecting a species. Three experiments were conducted where the physical attractiveness of the Dead Leaf Butterfly was manipulated. Two of the experiments used a representative American sample, while one of the experiments used a Polish sample. In all three studies: (1) Participants rated the Dead Leaf Butterfly as more physically attractive when its wings were open and displayed a black apex, an orange discal band, and a deep blue base than when its wings were closed and resembled a dried leaf with dark veins; and (2) those who scored high in humanitarianism-egalitarianism provided more support for protection from harm for the Dead Leaf Butterfly compared to those who scored low in humanitarianism-egalitarianism. Only in the studies where Americans participated did we find (1) those who were politically liberal indicated more support for the Dead Leaf Butterfly regardless of physical attractiveness as compared to those who were politically conservative, and (2) those who scored low in right-wing authoritarianism provided more support for protection from harm for the Dead Leaf Butterfly compared to those who scored high in right-wing authoritarianism. The differences observed between the American and Polish samples suggest that environmental attitudes are more polarized in the United States compared to Poland. These studies advance our knowledge of how attitudes toward animals are affected by the polarization of political attitudes toward the environment and provide insight for marketers when creating marketing strategies and designing appropriate messaging.  相似文献

School-shootings can enormously impact U.S. gun policy, but very little is known about the community mental health impact of school-shootings. We used difference-in-differences and event study analyses to compare stress-related ED visits in zip-codes within 5 miles (exposed) and in zip-codes 10–15 miles from (control) school-shootings before and after school-shootings using data from California, 2005–2011. School-shootings and fatal school-shootings were associated with annual increases of 0.7 and 1.5 stress-related ED visits per 1000 people, increases of 7% and 14%, respectively, compared to pre-shooting utilization. These previously unmeasured costs of school-shootings reinforce calls to prevent gun violence, especially in schools.  相似文献
