This paper examines the impact of fiscal policies on both the size and educational levels of immigrants in destination countries. We find that whether or not a country’s policies are attracting highly educated immigrants goes beyond the issue of the “welfare state”. Immigrants are making important distinctions between the different benefits provided by a receiving country’s government. Health and education spending are found to have a positive impact on the education levels of immigrants while the reverse is true for unemployment and retirement benefits. Welfare programs are found to be insignificant once other government programs/taxes and other factors are taken into account. These results imply that countries should be less concerned about whether they are a “big government” with regards to attracting immigrants, and more concerned with what types of benefits they offer.  相似文献

The stagnation of the American economy during the past decade is attributable to faulty policies at both the macro and micro level. The efforts to organize stimulus programs and manipulation tax rates create uncertainties that offset any supposed gains from Keynesian policies. At the same time, the failure to address major structural flaws in labor, real estate, free trade and positive rights have resulted in cumulative dislocations that require a shrinkage of government across the board to facilitate any reversal of economic fortune.  相似文献

Fertilizer use in Nigeria is estimated at 13 kg/ha, which is far below the 200 kg/ha recommended by the Food and Agricultural Organization (FAO). The objective of this investigation was to identify the determinant factors of farmers’ participation in Nigeria's Growth Enhancement Support Scheme (GESS). In addition, we determined the impact of the GESS on fertilizer use in rural areas. A total of 1,200 rural farmers were sampled across the six geopolitical zones of Nigeria. Results from the use of a recursive bivariate probit model indicated that GESS significantly impacted on the access and usage of fertilizer among the rural farmers; and that contact with extension agents, ownership of mobile phones, power for charging phone batteries, value output, mobile network coverage, ability to read and write were positive determinants of rural farmers’ participation in the GESS; whereas increased distance to registration and collection centers, and cultural constraints to married women reduced farmers’ tendency to participate in the GESS. The findings suggest that farmers’ participation in the GESS is a critical factor for raising fertilizer use in Nigeria. This implies that food security in sub‐Saharan Africa can be achieved by increasing the participation of rural farmers in the GESS.  相似文献

The purpose of the study is to understand whether it is still viable to use tax incentives to attract foreign direct investment (FDI) considering their effectiveness and costs to the country, and if not, what should be the alternative, effective, and viable means of promoting the vital FDI inflow. The study investigated various incentives provided by BOI, and other relevant sources available as secondary sources. However, the multinational enterprises (MNEs) are not attracting for investment in Bangladesh always with tax incentives and there are alternative means of attracting FDI such as direct financial grants, subsidies loan guarantees, etc. This paper focuses on tax incentives and the debate against the effectiveness and efficiency in attracting FDI.  相似文献

It has been well documented that Black homeseekers face discrimination in the housing market in the form of racial steering and other institutional policies and practices that are critical in limiting housing access. Less is known about the mechanisms that operate on the other side of real estate transactions to perpetuate racially segregated neighborhoods. We investigated whether White and Black brokers face segregation in the housing market. That is, to what extent do White and Black brokers differentially market property listings in neighborhoods of varying racial composition? Using real estate listings extracted from the websites of two of the largest New York City real estate brokerages, we examined whether Black and White brokers market properties primarily in Black and White neighborhoods, respectively; and whether, controlling for gender and experience level, Black brokers had a lower average price per square foot than White brokers. Results showed that Black brokers overwhelmingly marketed properties in Black neighborhoods, with fewer listings in White areas. Black brokers also marketed properties with an average price per square foot that was $197 lower than White brokers. Black brokers who worked in offices in Black neighborhoods had the lowest asking price of all brokers. Taken together, Black and White real estate brokers control a bifurcated market in NYC, perpetuating residential segregation and Black–White income and wealth disparities.  相似文献

This paper presents various approaches to the definition of the innovative activity of the population based on the results of a study performed by the Institute of Socioeconomic Development of Territories, Russian Academy of Sciences, in Vologda oblast in November 2012 by using econometric methods (probit models) for the assessment of the population’s creativity in relation to various social, demographic, and economic characteristics of respondents.  相似文献

This paper provides an estimate of the dynamics in expenditures on health care and education made from all sources in Russia in the 1995–2012 and viewed as investments in human capital. These data from Russia are compared with those from other countries. The problems of efficiency in the functioning of these systems and different affordability of these services are considered.  相似文献

This study examines the effectiveness of macroprudential policies in reducing the banks' risk during the COVID-19 pandemic and compares these results with the systemic banking crises years. Based on a sample of 624 banks across 40 countries during the period 2006–2020, we find that loosening capital-aimed macroprudential policies effectively reduced banks' risk during the COVID-19 pandemic, while this behavior led to increased risk during the systemic crises years. In contrast, tightening the remaining macroprudential policies during the systemic crises years and during the pandemic proved effective in reducing banks' risk. Furthermore, we show that the magnitude of the impact of macroprudential policies was stronger during the systemic crisis than that during the pandemic. Finally, we show that the results are driven by the capital requirement prudential policy, both during the systemic crisis and the COVID-19 pandemic, although the conservation buffer and the leverage limit also contributes to the ineffectiveness of these policies during the COVID-19 pandemic. The banks' leverage and loan growth also play an enhancing role of the effects of the macroprudential policies.  相似文献

Many local businesses have and are continuing to struggle as a result of the pandemic crisis due in part to reduced consumer spending. However, the motives behind why some consumers are more supportive than others toward local businesses in such a crisis are not adequately understood. We address this gap in the literature through three experimental studies where we examine how the core consumer value of religiosity explains consumer response to the crisis as consumers seek to act in ways that align with their value system. Study 1 (257 adults from MTurk) shows a positive relationship between religiosity and support for local businesses but only during a pandemic. Study 2 (307 adults from MTurk) shows that this relationship is greatest for local (vs. non-local) businesses, and caring for one's neighbors mediates this effect. Finally, Study 3 (200 adults from MTurk) uses advertising to prime focus on one's neighbors, revealing that a neighbors-focused ad increases local business support to similar levels for consumers of all religiosity levels. Findings build on belief congruence theory with implications for marketing practitioners in the current pandemic crisis and other crises of medical, environmental, and other origins.  相似文献
