What Explains the Union Membership Gap between Migrants and Natives?

This article explores the differences in unionization rates between migrant and native‐born workers in 23 European countries. It explores whether individual characteristics or contextual factors explain the variation across countries in the degree of trade unions’ inclusion of migrant workers. The analyses show that individual characteristics cannot explain the variation in the difference between migrant and native unionization rates. Characteristics of the industrial relations regime in the country of destination, in particular the institutional embeddedness of trade unions, affect the likelihood that migrants join trade unions as compared to native workers.     

Amino acid formula as a new strategy for diagnosing cow’s milk allergy in infants: is it cost-effective?

Aims: To estimate the cost-effectiveness of a new strategy that uses an amino acid formula in the elimination diet of infants with suspected cow’s milk allergy (CMA).

Materials and methods: This pharmacoeconomic study was developed from the perspective of the Brazilian Public Healthcare System. The new strategy proposes using an amino acid formula in the diagnostic elimination diet of infants (≤24 months) with suspected CMA. The rationale is that infants who do not respond to the amino acid formula do not suffer from CMA. Patients with a positive oral challenge test receive a therapeutic elimination diet based on Brazilian Food Allergy Guidelines. This approach was compared to the current recommendations of the Brazilian Food Allergy Guidelines. A decision model was constructed using TreeAge Pro 2012 software. Model inputs were based on a literature review and the opinions of a panel of experts. A univariate sensitivity analysis of incremental cost-effectiveness ratios was performed.

Results: The mean cost per patient of the new amino acid formula strategy was R$3,341.57, while the cost of the current Brazilian guidelines strategy was R$3,641.08. The mean number of symptom-free days per patient, which was used as an indicator of effectiveness, was 900.6 and 875.7 days, respectively. The new strategy is, therefore, dominant. In the sensitivity analysis, the dominance was maintained with parameter variation.

Limitations: In the absence of information in the literature, some premises were defined by a panel of specialists.

Conclusions: The new strategy, which uses an amino acid formula in the elimination diagnostic diet followed by an oral food challenge, is a dominant pharmacoeconomic approach that has a lower cost and results in an increased number of symptom-free days.     

Public Debt,Economic Growth and Inflation in African Economies

We analyse the relationship between public debt, economic growth and inflation in a group of 52 African economies between 1950 and 2012. The results indicate that the limits of public debt are negatively related to economic growth and exhibit, from a given level of debt, an inverted U behaviour regarding the relationship between economic growth and public debt. Briefly, the high levels of public debt are coincident with reduced rates of economic growth and rising levels of inflation. Our results for three specific geographical areas resemble those of the overall analysis, despite some differences. In North African countries, the growth rates of the gross domestic product (GDP) and inflation also show an inverted U behaviour as the ratio of public debt/GDP increases. The highest rate of economic growth is recorded when the ratio of public debt/GDP is below 30% of GDP and corresponds to an average inflation rate of 5.33%. An identical behaviour of the GDP growth rates and inflation also appears in Sub‐Saharan countries until the third interval (60–90%). However, the highest growth rate of the GDP and GDP per capita is registered when the public debt/GDP ratio is in the second interval (30–60%). For the countries of the Southern Africa Development Community, the highest average rate of economic growth (6.8%) is similar to North African countries, when the ratio public debt/GDP is below 30% of GDP, with an average inflation rate of 11%. A number of robustness analyses were performed and the great majority of them confirm the general analysis.     

On the nature and role of financial systems in Keynes’s entrepreneurial economies

In his debate with Bertil Ohlin, Keynes observed that entrepreneurs, when deciding to invest, have to be sure they will access the amount of finance necessary to initiate the investment process and that they will be able, when the time comes, to fund their debts in ways that are adequate to the profile of assets they are purchasing. In this statement, Keynes outlines the functions of financial systems in Entrepreneurial Economies, the type of economies he hypothesizes we live in. In entrepreneurial economies, investing firms have to be able to get hold of the necessary amount of means of payment required to purchase or order investment goods and to build balance sheets where in- and outflows of cash are broadly matched within reasonable margins of safety. This means that financial systems’ primary role in Keynesian economics is not to allocate savings or capital but to allocate liquidity and to allow investors to build liquid balance sheets. The article develops this proposition, presenting Keynes's basic concepts on the matter and showing how modern financial systems perform their role.     

Smiles over Frowns: When Curved Lines Influence Product Preference

The present research examined the possibility that subtle face‐like features (a smile‐ or a frown‐like line) on a product can influence evaluations of and preferences for that product. The same within‐participants experiment was conducted twice, once in the United Kingdom and once in Colombia: participants viewed four variants (concave [smile‐like] line, convex [frown‐like] line, straight line, line absent) of three different products (tea, shampoo, juice) and both evaluated the products on visual analogue scales and completed a forced choice decision task. The results revealed a general tendency across scales, products, and countries for the participants to rate products more positively and to choose products more frequently when they displayed a concave line relative to a convex line; comparisons with the straight line and absent line conditions suggested that the effects were present for both concave and convex lines, but were stronger in the concave instance. These findings provide both a deeper theoretical understanding of the influence of subtle cues on evaluation and decision making, and concrete, practical information for both product designers and marketers.     

The Need to Give Gratuitously: A Relevant Concept Anchored in Catholic Social Teaching to Envision the Consumer Behavior

The “gift exchange theory” articulated by Marcel Mauss, along with his core concept of a threefold obligation (giving/receiving/returning), is the dominant theoretical framework used to explain the majority of gift issues in marketing. This perspective assumes that some interest always lies behind gifts, such that a gift always implies a counterpart of receiving something in return. Despite the relevance of this approach in understanding the day-to-day consumer behavior, this paper presents empirical cases where the consumer is also able to give freely, that is to say without implying a counterpart or even expecting it. To explain those empirical cases, we mobilize a key teaching of the Catholic Church: the “gratuitous gift” and then introduce the concept of the “need to give.” We show that gratuitousness is a relevant concept to understand most of gifts made by consumers, and we develop the normative aspect of gratuitous gift for ethical marketers (i.e., what ethical marketers should consider to understand consumers properly and in a more humanistic way). We also show that Catholic Social Teaching offers an appropriate anthropology to understand consumer behaviors motivated by this need for gratuitousness. To conclude, we propose further avenues of research.     

Potential Impacts of Transatlantic Trade and Investment Partnership (T-TIP) on the Fresh Vegetable and Beef Trade

ABSTRACT

The Transatlantic Trade and Investment Partnership (T-TIP) negotiations influence the global economic position of both the European Union (EU) and the United States (U.S.). Agricultural issues are an important part of the negotiation. There have been several analyses of the aggregate impacts of a T-TIP agreement. This report analyzes the commodity impacts on trade for fresh vegetables and beef. Vegetables represent the situation where the U.S. is a growing net importer and the EU has substantial potential for expanding exports to the U.S. in this highly competitive marketplace. Beef represents the situation where sanitary and phytosanitary restrictions on hormone use in production have prohibited consumer choices from being revealed in the marketplace for both the EU and the U.S. The authors provide insight into where the comparative advantages lie in freer trade situations.
