Although many studies have analyzed the behavior of high‐skilled migration to the United States, few have focused on the escalating migration of Mexican entrepreneurs, and particularly on the determinants of this kind of high‐skilled migration. This article addresses this gap through a qualitative approach conforming to quantitative procedures, based on 20 in‐depth interviews applied to Mexican entrepreneurs working and/or living in the United States. Theoretically, a mixed‐embeddedness approach guides this research because it allows examining both the individual characteristics of Mexican entrepreneurs, and the influence of the home and host countries' institutional contexts on their business endeavors. Findings revealed Mexico's institutional weaknesses, such as insecurity, corruption, and bureaucracy, are important drivers of migration but so are the perception of a friendly U.S. fiscal system, the search for a better quality of life, and the appeal of a more transparent business environment. 相似文献

A compelling body of research has found that investments in knowledge from other firms and universities spill over to enhance the performance of entrepreneurial firms. This literature has shown that firm performance is positively related to investments in new knowledge by other firms and research universities. This paper addresses a gap in the literature by positing that public sector knowledge is also conducive to enhancing performance by knowledge intensive entrepreneurial (KIE) firms. Our findings suggest that the public sector provides a fertile source of knowledge for enhancing KIE firm performance.

Supersaturated designs (SSDs) constitute an important class of fractional factorial designs that could be extremely useful in factor screening experiments. Most of the existing studies have focused on balanced designs. This paper provides a new lower bound for the \(E(f_{NOD})\)-optimality measure of SSDs with general run sizes. This bound is a generalization of existing bounds since it is applicable to both balanced and unbalanced designs. Optimal multi and mixed-level, balanced and nearly balanced SSDs are constructed by applying a k-circulant type methodology. Necessary and sufficient conditions are introduced for the generator vectors, in order to pre-ensure the optimality of the constructed k-circulant SSDs. The provided lower bounds were used to measure the efficiency of the generated designs. The presented methodology leads to a number of new families of improved SSDs, providing tools for directly constructing optimal or nearly-optimal k-circulant designs by just checking the corresponding generator vector. 相似文献

We present original survey data on preferences for foreign aid in 24 donor countries from 2005 to 2008. On publicly-funded foreign aid (Official Development Assistance, or ODA), we find patterns that are consistent with a standard model of democratic policy formation, in which donations are treated as a pure public good. Controlling for perceptions of current ODA, we show that individual preferences for ODA are (i) negatively correlated with relative income within a country-year; and (ii) positively correlated with inequality at the country level. We extend the analysis to explain variation in the gap between desired aid and actual ODA, arguing that lobbying by high-income special interest groups can divert resources away from the median voter’s preferred level of aid. Consistent with this, we observe that ODA is significantly lower where policymakers are more susceptible to lobbying. Finally, we present a novel test of competing “crowding out” hypotheses. Self-reported private aid donations are negatively correlated with actual ODA, and positively correlated with perceived ODA. This finding is consistent with an emerging argument in the literature, whereby ODA crowds out private aid by enabling charities to forego fundraising activities and crowds in private aid through a signaling channel. 相似文献

Coupons research has typically focused on single-coupon redemption, with scant attention devoted to multiple, competing coupons. To bridge this gap, we observe supermarket shoppers who used their smartphones to scan products in-store, receiving both coupons for the scanned product and several others as a result. We model the determinants of redemption in this context, particularly net price range (NPR), coupon value, brand loyalty, and number of coupons. Latent class analysis uncovers two consumer segments: brand-focused shoppers (79.9%), who use internal reference prices, and deal-prone shoppers (20.1%), who use stimulus-based reference prices. Targeting by means of segment membership, NPR, and loyalty is indispensable: the same $0.50 coupon can have a redemption probability as low as 30% and as large as 80%, depending on these characteristics. Overall, the study sheds light on drivers of redemption under competition and provides managers with a blueprint to improve redemption rates by targeting shoppers with customized coupons. 相似文献

An online survey of 1,201 U.S. residents was conducted in April 2015 to better understand individuals’ perceptions of prominent areas of corporate social responsibility (CSR) in the food supply chain. Demographic and household consumption information, including supermarket patronage, was collected. Each respondent completed best–worst tasks for CSR areas designed to elicit their relative importance of CSR areas. Overall, health and safety were perceived as the most important CSR area, and environment was prioritized second. Indicating gender as female and/or reporting age over 65 was positively correlated with the relative importance placed on health and safety, but negatively correlated with the size of preference share for nearly all other CSR areas investigated. Membership in the younger age categories was positively correlated with the size of the preference shares devoted to procurement, labor, fair trade, and biotechnology. 相似文献

Strategic flexibility is a vital capability for new ventures to update their strategies in a timely manner. However, the role of external knowledge sources in new ventures’ endeavours to develop strategic flexibility are unclear. Drawing on the knowledge‐based and relational views, we explore the effect of two sources of external knowledge: new product development (NPD) alliances, representing tightly coupled sources, and loosely coupled sources such as industry associations. Our field study of 148 high‐tech ventures found that the extent to which firms utilize knowledge from NPD alliances has a curvilinear relationship with strategic flexibility, whereas the extent to which firms utilize loosely coupled sources has a positive linear relationship with strategic flexibility. We also found that in new ventures, decentralization of decision‐making and institutional support enhance knowledge integration, positively moderating these relationships. 相似文献
