In this paper we first show that the timing and skill distribution of Immigrants to the U.S. between 1970 and 2014 imply they did not contribute to the decline in the wages of native, non-college educated workers – including high school dropouts – at the national level. We then review other evidence at the local level, which implies immigration is not associated with lower non-college wages. Rather, higher immigration seems associated with higher average (and college-level) wages. Local externalities, complementarities, efficient specialization and appropriate technological choice suggest at least part of the positive association is causal.  相似文献

This paper extends the findings in Chen and Lee (2007) to show that the use of congestible public goods can produce both local and global indeterminacy in a two‐sector endogenous growth model with productive public services financed by income taxation. Basically, we observe the effects on growth rates by changing parameters, and compare the case of a single steady‐state with the emergence of dual steady‐states, identifying the feasible ways to avoid a possible low‐growth poverty trap. The novelty of our analysis is to detect the presence of global indeterminacy by making use of the Bogdanov‐Takens bifurcation theorem. Some examples are also provided to achieve concrete policy implications.  相似文献

Mortality forecasting has crucial implications for insurance and pension policies. A large amount of literature has proposed models to forecast mortality using cross-sectional (period) data instead of longitudinal (cohort) data. As a consequence, decisions are generally based on period life tables and summary measures such as period life expectancy, which reflect hypothetical mortality rather than the mortality actually experienced by a cohort. This study introduces a novel method to forecast cohort mortality and the cohort life expectancy of non-extinct cohorts. The intent is to complete the mortality profile of cohorts born up to 1960. The proposed method is based on the penalized composite link model for ungrouping data. The performance of the method is investigated using cohort mortality data retrieved from the Human Mortality Database for England & Wales, Sweden, and Switzerland for male and female populations.  相似文献

In the coming years, the new EU Regulation on Novel Food is likely to facilitate the development of a niche market for insects and insect‐based ingredients in many European countries. In this research, the aim is to explore the relationship between willingness to try (WTT) and behavior of eating insects, where the independent variables are food neophobia, sensory property expectations, and previous consumption. In total, 88 Italian participants took part in the study. The food neophobia scale (FNS) was constructed using 9 of the 10 items from the original FNS, and a Structural Equation Modeling approach was used to test the research hypotheses. The results show that males are more open to trying insects than females, and food neophobia is negatively correlated with the willingness to eat insects. Findings also indicate that the first exposure to insects positively increases consumers’ sensory property expectations. Intention to try is a strong predictor of the behavior of eating insects. People who scored lower on the FNS were more likely to try (intention) and consequently eat insects (behavior). These findings enhance knowledge about factors which could lead to lower levels of negative prejudice and greater willingness to taste edible insects among Western consumers. Finally, some marketing implications are discussed, like the need of information campaigns to emphasize positive sensory attributes of edible insects to increase the WTT this unfamiliar food.  相似文献

Marketing research has a limited understanding about the effects arising from emotional shifts (i.e., the transition from one emotion to another) during the same advertising message. This paper sheds light on this topic through two studies. Study 1 examines whether an advertising message that features a negative-to-positive emotional shift (i.e., a shift from a negative to a positive emotion) generates greater recall of an advertised brand than an advertising message with a neutral-to-positive emotional shift (i.e., a shift from a neutral to a positive emotion) or one with no emotional shift. Study 2 examines whether an advertising message that simulates a buyer-seller encounter—with the seller reproducing a negative-to-positive emotional shift via facial expressions—generates a greater recall of the advertised content than an identical advertisement with no emotional shift. Results confirm that a negative-to-positive shift facilitates the recall of both the brand and the advertised information.  相似文献
