Natural-hyped products are receiving greater attention from and acceptance by consumers worldwide. Environmental factors that foster the demand for natural-hyped products, specifically hemp-based products include the deregulation of the cannabis industry and greater consumer desire for natural foods. Adding to this, the strategic use of stimulant type of cues (e.g., a cannabis leaf) included in product logos, ads, and packaging, seems to create hype associations when evaluating hemp-based products. In this context, this study presents empirical evidence (three experiments and two qualitative studies) that illustrates consumer preference for hemp-based products over ones that do not include hemp as an ingredient (hemp-free). The research focuses on identifying the psychological determinant that orients consumers towards hemp-based products. Findings suggest that the perceived naturalness is the psychological mechanism behind consumers positive evaluation of hemp-based products. Moreover, this study presents evidence that this evaluation is enhanced by the consumer's need for stimulation. Implications of the findings for the role of perceived naturalness and the need for stimulation in marketing strategies are discussed. 相似文献

The theorization of the relationship between organizational investments in career development and individual success remains underdeveloped, and empirical tests of this relationship, which have been dispersed among several disciplinary areas, have produced inconsistent results. Addressing these issues, the purpose of this article is to propose a theoretical framework that illustrates why and how organizational career management practices translate into career success and under what circumstances the relationship is effective. Using a systematic review of empirical studies on career management practices and objective success, we identify three theoretical mechanisms - developmental, informational, and relational - and two groups of contingency factors that explain this relationship. Our framework advances the extant literature on organizational career management and provides suggestions to companies for designing effective career management systems. 相似文献

In this paper we suggest that the dual role played by the IMF, as a creditor and as a monitor of economic reforms, might explain the lack of credibility of the Fund threat of sanctioning non-compliance with conditionality. Specifically, we show that the IMF's desire to preserve its reputation as a good monitor may distort its lending decisions towards some laxity. Moreover, such distortionary incentives may be exacerbated by the length of the relationship between a country and the Fund. Estimating a dynamic panel of 53 middle-income countries, for the period 1982–2001, we find that a longer relationship does increase IMF disbursements. 相似文献

This paper proposes an explanation for two empirical puzzles surrounding initial public offerings (IPOs). Firstly, it is well
documented that IPO underpricing increases during “hot issue” periods. Secondly, venture capital (VC) backed IPOs are less
underpriced than non-venture capital backed IPOs during normal periods of activity, but the reverse is true during hot issue
periods: VC backed IPOs are more underpriced than non-VC backed ones. This paper shows that when IPOs are driven by the initial
investor’s desire to exit from an existing investment in order to finance a new venture, both the value of the new venture
and the value of the existing firm to be sold in the IPO drive the investor’s choice of price and fraction of shares sold
in the IPO. When this is the case, the availability of attractive new ventures increases equilibrium underpricing, which is
what we observe during hot issue periods. Moreover, I show that underpricing is affected by the severity of the moral hazard
problem between an investor and the firm’s manager. In the presence of a moral hazard problem the degree of equilibrium underpricing
is more sensitive to changes in the value of the new venture. This can explain why venture capitalists, who often finance
firms with more severe moral hazard problems, underprice IPOs less in normal periods, but underprice more strongly during
hot issue periods. Further empirical implications relating the fraction of shares sold and the degree of underpricing are
presented.

In order to identify the effect of academic entrepreneurship on science, this work compares the publication performance of entrepreneurial scientists with that of conventional scientists. Using Stokes's ‘quadrant model’, this paper examines how the entrepreneurial orientation affects scientific performance. The results on advanced materials research in Japan found that (i) entrepreneurial scientists publish more papers than conventional scientists do; (ii) the papers of conventional scientists demonstrate better citation performance than those of entrepreneurial scientists do, on average; (iii) coming to the top-cited papers, entrepreneurial scientists show higher propensity for publishing high-impact papers than conventional scientists do; and (iv) the portfolio interdisciplinarity of papers authored by entrepreneurial scientists is higher than that of conventional scientists. Although the influence of academic entrepreneurship on scientific performance is still unclear, our findings suggest that entrepreneurial scientists could make a relatively large contribution to furthering the scientific frontier by relying on innovation rather than convention. 相似文献

This paper investigates the impact of migration on the food expenditure and household food security status of migrant‐sending households using data from eastern Indonesia. We find that migration significantly increases food expenditure and overall household expenditure. Combining the food frequency and food consumption module of the Indonesia Family Life Survey (East), this paper shows that having at least one migrant in the family increases the composite index of Food Consumption Score, as well as the family's food security. Evaluation of food diversity also shows that migration increases expenditure on six out of ten food groups. 相似文献

Focusing on credit risk modelling, this paper introduces a novel approach for ensemble modelling based on a normative linear pooling. Models are first classified as dominant and competitive, and the pooling is run using the competitive models only. Numerical experiments based on parametric (logit, Bayesian model averaging) and nonparametric (classification tree, random forest, bagging, boosting) model comparison shows that the proposed ensemble performs better than alternative approaches, in particular when different modelling cultures are mixed together (logit and classification tree).

This work assesses the causal impact of the EU trade preferences granted to the Southern Mediterranean Countries (SMCs) in agriculture and fishery products over the period 2004–2014. It overcomes some of the weaknesses of previous assessments and presents several methodological improvements. Firstly, it relies on a continuous treatment – i.e. preferential margins – to capture the ‘average treatment effect’ of trade preferences, rather than on a binary treatment based on dummy variables. Secondly, it uses highly disaggregated data at sectoral level in order to evaluate properly the preferential treatment. Thirdly, it applies a non-parametric matching technique for continuous treatment – specifically, a generalized propensity score matching. The results show, on the one hand, that the impact of the EU preferences is positive and significant on SMCs trade and is better evaluated using impact evaluation techniques. On the other hand, they demonstrate that the relationship between preferences and trade flows is asymmetric and warn against the risk of providing too much of a good thing. These results raise important issues for policy-making. First, they demonstrate that raising the level of preferences is not the solution to foster the SMCs trade towards EU. Second, that the policy-makers should put more emphasis on complementary factors other than trade barriers. 相似文献

Aim: To assess the cost-effectiveness of nutrition education by dedicated dietitians (DD) for hyperphosphatemia management among hemodialysis patients.Materials and methods: This was a trial-based economic evaluation in 12 Lebanese hospital-based units. In total, 545 prevalent patients were cluster randomized to DD, trained hospital dietitian (THD), and existing practice (EP) groups. During Phase I (6 months), DD (n?=?116) received intensive education by DD trained on renal nutrition, THD (n?=?299) received care from trained hospital dietitians, and EP (n?=?130) received usual care from untrained hospital dietitians. Patients were followed-up during Phase II (6 months).Results: At baseline, EP had the lowest weekly hemodialysis time, and DD had the highest serum phosphorus and malnutrition-inflammation score. The additional costs of the intervention were low compared with the societal costs (DD: $76.7, $21,007.7; EP: $4.6, $18,675.4; THD: $17.4, $20,078.6, respectively). Between Phases I and II, DD showed the greatest decline in services use and societal costs (DD: –$2,364.0; EP: –$1,727.7; THD: –$1,105.7). At endline, DD experienced the highest decrease in adjusted serum phosphorus (DD: –0.32; EP: +0.16; THD: +0.04?mg/dL), no difference in quality-adjusted life-years (QALY), and the highest societal costs. DD had a cost-effectiveness ratio of $7,853.6 per 1?mg decrease in phosphorus, compared with EP; and was dominated by THD. Regarding QALY, DD was dominated by EP and THD. The results were sensitive to changes in key parameters.Limitations: The analysis depended on numerous assumptions. Interpreting the results is limited by the significant baseline differences in key parameters, suggestive of higher baseline societal costs in DD.Conclusions: DD yielded the greatest effectiveness and decrease in societal costs, but did not affect QALY. Regarding serum phosphorus, DD was likely to be cost-effective compared with EP, but had a low cost-effectiveness probability compared with THD. Regarding QALY, DD was not likely to be cost-effective. Assessing the long-term cost-effectiveness of DD, on similar groups, is recommended. 相似文献

The fundamental question of whether offshoring is value enhancing and, more specifically, whether Italian manufacturing firms that undertake offshoring benefit from higher productivity and profitability is explored. Using data from the tenth wave of the “Survey on Manufacturing Firms” conducted by Unicredit‐Capitalia, it was found that, compared with domestic firms, firms relocating activities to a foreign country have different characteristics, and “better” firms might self‐select into offshoring decision. To disentangle the effect of offshoring on firms' performances from the effect of firm characteristics, several variants of propensity score matching are used. A mild and insignificant positive effect of offshoring on profitability was found and also evidence of a statistically significant positive effect of offshoring on productivity. 相似文献
