Food price inflation in Brazil in the 12 months to June 2008 was 18%, whereas overall inflation was 7%. Using spatially disaggregated monthly data on consumer prices and two different household surveys, we estimate the welfare consequences of these food price increases, and their distribution across households. Because Brazil is a large food producer, with a predominantly wage‐earning agricultural labour force, our estimates include general equilibrium effects on market and transfer incomes, as well as the standard estimates of changes in consumer surplus. Although the expenditure (or consumer surplus) effects were large, negative and markedly regressive everywhere, estimates of the market‐income effect were positive and progressive, particularly in rural areas. Because of this effect on the rural poor, and of the partial protection afforded by increases in two large social assistance benefits, the overall impact of higher food prices in Brazil was U‐shaped, with middle‐income groups suffering larger proportional losses than the very poor. Nevertheless, as Brazil is 80% urban, higher food prices still led to a greater incidence and depth of poverty at the national level. 相似文献

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield,
concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance
analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are
used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes
or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or
impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the
main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division
of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric
technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR.
It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future
research could lead. 相似文献

This paper applies time series analysis to study how the gap between a number of countries and the USA evolves through time. As other authors, it is found that time series analysis provides a better insight into the concept of convergence than the cross sectional one. The econometric results show that the stochastic behaviour of the output disparity varies considerably: neither the steady-state equilibrium nor the speed of convergence are unique and constant across countries and time. In general, there is catching up for European countries, convergence for East and South Asian countries, and neither of them for Latin American countries. 相似文献

This paper provides insights about how customer equity estimates can help businesses monitor the competition as well as aid managers in making their marketing investment decisions, and how companies can employ their marketing investments to maximize current and future yield/returns. The article concerns itself with the current offer of cellphone providers and their main products. The research includes survey data through interviews with 302 cellphone users of Sao Paulo, Brazil. The study uses this data combined with a number of economic assumptions and a financial marketing model to create an insight in customer equity values of cellphone providers in the region. The scenario dated October 2005 is that the estimated customer equity of the service provider Vivo is, respectively, 93 and 91% larger than those of competing providers Claro and TIM. The research underlines that on average the customer equity flowing from the post-paid segment is 3.5 times larger than that of the pre-paid. In addition to these results the study provides the customer lifetime value (CLV) estimates for Claro's, TIM's and Vivo's pre- and post-paid customers and analyzes the retention and loss figures of CLV. Also a discussion follows of the implications that these values will likely have for the companies' marketing strategy. 相似文献

This study investigated the meanings attached to leisure by low-income young consumers. In order to achieve this research objective, the study was conducted in a low-income community in the city of Rio de Janeiro. We used semi-structured interviews with community leaders and observation to acquire a preliminary knowledge of the field. We then interviewed 80 young people with ages varying from 15 to 25?years old. The data were treated qualitatively and quantitatively, using cluster analysis. The results showed, as expected, that these consumers have limited resources for leisure activities, due to lack of money, time or both. However, although the subjects recognise leisure as an important part of their lives, they attribute different meanings to it. Also, their understanding of free time and leisure varies somewhat. The findings provide evidence that these consumers' view of leisure, to some extent, resembles a pre-industrial understanding of leisure, associated with time for rest and time with family and friends. The results also permitted the identification of four different clusters, based on the meanings attributed to leisure and free time, individual aspirations and demographic characteristics. 相似文献

Abstract Cross-sector inter-organizational partnerships, alliances and networks have become extremely popular. Yet, we may expect competing societal-level institutional logics to play an important role in cross-sector alliances, hence making their management central to alliance success. This article responds to the general research question: How do participants of public–private joint ventures manage competing institutional logics? Based on in-depth interviews we empirically characterize two competing logics in a cross-sector collaborative and identify two practices used to cope with them. 相似文献

This paper proposes a model to conduct macro stress test of credit risk for the banking sector based on scenario analysis. We employ an original bank-level data set that splits bank credit portfolios in 21 granular categories, covering household and corporate loans. The results corroborate the presence of a strong procyclical behavior of credit quality, and show a robust negative relationship between the logistic transformation of non-performing loans (NPLs) and GDP growth, with a lag response of up to three quarters. The results also indicate that the procyclical behavior of loan quality varies across credit types. This is novel in the literature and suggests that banks with larger exposures to highly procyclical credit types and economic sectors would tend to undergo sharper deterioration in the quality of their credit portfolios during an economic downturn. Lack of sufficient portfolio granularity in macro stress testing fails to capture these effects and thus introduces a source of bias that tends to underestimate the tail losses stemming from the riskier banks in a system. 相似文献

Black American women are shrinking in height at a faster rate than other groups, a phenomenon that has consequences for the physical health and economic well-being of black females. Relative to the cohort born from 1955 to 1974, the most recent cohort (1970–1986) of black American women and girls have lost more than half an inch (approximately 0.56) in height. Adult height is a measure of net nutrition acquired during childhood and adolescence and is correlated with a wide variety of economic and health outcomes. Simultaneously, the body mass index (BMI) among blacks has also increased at a faster rate than whites in both the periods of 1988–1994 (1.06 kg/m2) and 1999–2002. Black women and girls, in particular, experienced the greatest increase in BMI since the 1990s. Evidence that black American women are shrinking and BMI is growing highlights the need to examine the nutritional intake of black girls during childhood and adolescence; early nutritional deficiencies have persistent impact over their life course. In this policy brief, we consider several public health policy interventions that affect black girls’ nutritional intake across the life course, particularly during childhood and adolescence. 相似文献

After rising during mostbut not allof the 196085period, inequality in Chile seems to have stabilized since around1987. Following the stormy period of economic and politicalreforms of the 1970s and 1980s, no statistically significantLorenz dominance results could be detected since 1987. Scalarmeasures of inequality confirm this picture of stability, butsuggest a slight change in the shape of the density function,with some compression at the bottom being "compensated for"by a stretching at the top. As inequality remained broadly stable,sustained economic growth led to substantial welfare improvementsand poverty reduction, according to a range of measures andwith respect to three different poverty lines. Poverty mixedstochastic dominance tests confirm this result. All of thesefindings are robust to different choices of equivalence scales. 相似文献
