A growing body of empirical work measunng different types of cultural traits has shown that culture matters for a variety of economic outcomes. This paper focuses on one specific aspect of the ...relevance of culture: its relationship to institutions. We review work with a theoretical, empirical, and historical bent to assess the presence of a two-way causal effect between culture and institutions.
Abstract
We examine a determinant of cultural persistence that has emerged from a class of models in evolutionary anthropology: the similarity of the environment across generations. Within these ...models, when the environment is more stable across generations, the traits that have evolved up to the previous generation are more likely to be suitable for the current generation. In equilibrium, a greater value is placed on tradition and there is greater cultural persistence. We test this hypothesis by measuring the variability of climatic measures across 20-year generations from 500 to 1900. Employing a variety of tests that use different samples and empirical strategies, we find that populations with ancestors who lived in environments with more cross-generational instability place less importance on maintaining tradition today and exhibit less cultural persistence.
We study the historical origins of cross-country differences in the male-to-female sex ratio. Our analysis focuses on the use of the plough in traditional agriculture. In societies that did not use ...the plough, women tended to participate in agriculture as actively as men. By contrast, in societies that used the plough, men specialized in agricultural work, due to the physical strength needed to pull the plough or control the animal that pulls it. We hypothesize that this difference caused plough-using societies to value boys more than girls. Today, this belief is reflected in male-biased sex ratios, which arise due to sex-selective abortion or infanticide, or gender-differences in access to family resources, which results in higher mortality rates for girls. Testing this hypothesis, we show that descendants of societies that traditionally practiced plough agriculture today have higher average male-to-female sex ratios. We find that this effect systematically increases in magnitude and statistical significance as one looks at older cohorts. Estimates using instrumental variables confirm our findings from multivariate OLS analysis.
Traditional economic interpretations have not been successful in explaining differences in saving rates across countries. One hypothesis is that savings respond to cultural specific social norms. The ...accepted view in economics so far is that culture does not have any effect on savings. We revisit this evidence using a novel dataset, which allows us to study the saving behavior of up to three generations of immigrants in the United Kingdom. Against the backdrop of existing evidence, we find that cultural preferences are an important explanation for cross-country differences in saving behavior, and their relevance persists up to three generations.

This paper reviews the literature on gender and culture. Gender gaps in various outcomes (competitiveness, labour force participation, and performance in mathematics, among many others) show ...remarkable differences across countries and tend to persist over time. The economics literature initially explained these differences by looking at standard economic variables such as the level of development, women’s education, the expansion of the service sector, and discrimination. More recent literature has argued that gender differences in a variety of outcomes could reflect underlying cultural values and beliefs. This article reviews the literature on the relevance of culture in the determination of different forms of gender gap. I examine how differences in historical situations could have been relevant in generating gender differences and the conditions under which gender norms tend to be stable or to change over time, emphasizing the role of social learning. Finally, I review the role of different forms of cultural transmission in shaping gender differences, distinguishing between channels of vertical transmission (the role of the family), horizontal transmission (the role of peers), and oblique transmission (the role of teachers or role models).
Multiple sclerosis (MS) is an autoimmune chronic disease characterized by inflammation and demyelination of the central nervous system (CNS). Despite numerous studies conducted, valid biomarkers ...enabling a definitive diagnosis of MS are not yet available. The aim of our study was to identify a marker from a blood sample to ease the diagnosis of MS. In this study, since there is evidence connecting the serotonin pathway to MS, we used an ELISA (Enzyme-Linked Immunosorbent Assay) to detect serum MS-specific auto-antibodies (auto-Ab) against the extracellular loop 1 (ECL-1) of the 5-hydroxytryptamine (5-HT) receptor subtype 2A (5-HT2A). We utilized an ELISA format employing poly-D-lysine as a pre-coating agent. The binding of 208 serum samples from controls, both healthy and pathological, and of 104 serum samples from relapsing-remitting MS (RRMS) patients was tested. We observed that the serum-binding activity in control cohort sera, including those with autoimmune and neurological diseases, was ten times lower compared to the RRMS patient cohort (
= 1.2 × 10
), with a sensitivity and a specificity of 98% and 100%, respectively. These results show that in the serum of patients with MS there are auto-Ab against the serotonin receptor type 2A which can be successfully used in the diagnosis of MS due to their high sensitivity and specificity.
Conventional economic analyses have not been successful in explaining differences in living arrangements and particularly the dramatic increase in the fraction of young adults living with their ...parents in Mediterranean Europe. This paper presents a cultural interpretation. I argue that the sexual revolution of the 1970s-by liberalizing parental attitudes-had a differential impact on living arrangements in Northern and Southern Europe on account of the closer parent-child ties in Southern Europe. Such an interpretation can easily explain both the shift in living arrangements over time and also observed North-South differentials. It receives support from data on the living arrangements of second-generation immigrants in the United States, both in 1970 and 2000. This duplication of the European pattern in a neutral environment, with the same unemployment benefits, the same welfare code, and the same macroeconomic conditions suggests a major role for culture in determining living arrangements.

We study the importance of family ties on economic behavior. We define our measure of family ties using individual responses from the World Value Survey (WVS) regarding the role of the family and the ...love and respect that children are expected to have for their parents in 81 countries. We show that with strong family ties home production is higher and families larger, labor force participation of women and youngsters, and geographical mobility lower. To assess causality, we look at the behavior of second generation immigrants. Our results overall indicate a significant influence of the strength of family ties on economic outcomes.

The study examines the historical origins of existing cross-cultural differences in beliefs and values regarding the appropriate role of women in society. We test the hypothesis that traditional ...agricultural practices influenced the historical gender division of labor and the evolution of gender norms. We find that, consistent with existing hypotheses, the descendants of societies that traditionally practiced plough agriculture today have less equal gender norms, measured using reported gender-role attitudes and female participation in the workplace, politics, and entrepreneurial activities. Our results hold looking across countries, across districts within countries, and across ethnicities within districts. To test for the importance of cultural persistence, we examine the children of immigrants living in Europe and the United States. We find that even among these individuals, all born and raised in the same country, those with a heritage of traditional plough use exhibit less equal beliefs about gender roles today.
CXCR4 receptor and its unique ligand, the CXCL12 chemokine, have been recently implicated in cancer metastasis. Evidence about the role of CXCR4/CXCL12 axis has been reported in several cancers ...including melanoma. Our goal was to investigate if CXCR4 expression has a prognostic value in malignant melanoma.
Immunohistochemical expression of CXCR4 was evaluated on 71 specimens of primary cutaneous melanoma with a Breslow tumor thickness of >1 mm after radical resection. Associations between baseline patient features and tumors were analyzed by chi(2) test. The prognostic value of CXCR4 expression was evaluated by univariate and multivariate analyses adjusted by age, sex, Breslow tumor thickness, presence of ulceration, and sentinel lymph node metastases.
CXCR4 expression was detected in 31 of 71 (43.6%) primary cutaneous melanomas. Membrane or cytoplasmic staining for CXCR4 protein was absent in 56% of the tumors. The positive cases were divided into three score classes according to their staining: low in 15 cases (21%), moderate in 10 (14%), and high in 6 (8%). After a median follow-up of 38 months, 26 patients progressed (16 of 26 expressed CXCR4) and 19 died (12 of 19 expressed CXCR4). The CXCR4 expression on tumor cells was correlated with an unfavorable prognosis with a median disease-free and overall survival of 22 and 35 months, respectively. The hazard ratios of relapse and death, compared with patients with CXCR4-negative tumors, were 2.5 (95% confidence interval, 1.2-6.1) and 3.1 (95% confidence interval, 1.1-7.2), respectively. Median time-to-event (progression and survival) was not reached in patients with CXCR4-negative tumors. In the multivariate analysis, CXCR4 expression, presence of ulceration, and sentinel lymph node status emerged as independent prognostic factors.
This article provides the first evidence that CXCR4 expression could be an independent and powerful prognostic marker in primary cutaneous malignant melanomas.
