    This study investigates the rationale behind the 2007 removal of the fodder subsidy in Jordan and the effects this had on livestock owners in the Northern Badia. Furthermore, it examines possible solutions for improving the efficiency of the sector as well as its sustainability. The government’s decision to lift the subsidy was due to the pressure of rising world cereal prices on the national budget deficit. Owners in the Northern Badia as a result had to sell off around half of their flock. Consequently, there has been a rise in disease among livestock as well as higher prices for consumers. The intention of the Jordanian government is to phase out much of the livestock sector and absorb livestock owners into other, more profitable sectors. This intention however, disregards the importance of the sector as it provides employment to the entire family and the necessary household consumption of livestock products for a poor stratum of society. Livestock represent the livelihoods of the Bedouin in the Badia and the nation’s cultural heritage. Moreover, livestock owners lack the skills to transition into other sectors. Therefore, this study examines possible solutions for sustaining the sector. Cooperatives, income diversification, rangeland management, domestic fodder production, human resource development and a reform of the sector’s infrastructure are suggestions put forth with the acknowledgement that future research is still required to understand how this sector can be efficiently developed

    Does urbanization mean bigger governments?

    This paper proposes urbanization as a determinant of government size. As people move to cities, their demand for a more de ned set of regulations, but also for basic health, education, and income standards rises. Our theoretical framework determines how the regional distribution of the population a ects government size. We test this theory on panel data of 175 countries from 1960 to 2010 and two state-level samples from Colombia and Germany. Results demonstrate a strong positive e ect from urbanization on government spending, with a 1 percent increase in the amount of urban citizens leading to a 0.2 percent rise in public expenditure. Our ndings indicate that public sectors may become more important as worldwide urbanization is progressing. This result underlines why government e ectiveness and the quality of public goods provision will be even more important in the future

    Genetic background modulates phenotypes of serotonin transporter Ala56 knock-in mice

    BACKGROUND: Previously, we identified multiple, rare serotonin (5-HT) transporter (SERT) variants in children with autism spectrum disorder (ASD). Although in our study the SERT Ala56 variant was over-transmitted to ASD probands, it was also seen in some unaffected individuals, suggesting that associated ASD risk is influenced by the epistatic effects of other genetic variation. Subsequently, we established that mice expressing the SERT Ala56 variant on a 129S6/S4 genetic background display multiple biochemical, physiological and behavioral changes, including hyperserotonemia, altered 5-HT receptor sensitivity, and altered social, communication, and repetitive behavior. Here we explore the effects of genetic background on SERT Ala56 knock-in phenotypes. METHODS: To explore the effects of genetic background, we backcrossed SERT Ala56 mice on the 129 background into a C57BL/6 (B6) background to achieve congenic B6 SERT Ala56 mice, and assessed autism-relevant behavior, including sociability, ultrasonic vocalizations, and repetitive behavior in the home cage, as well as serotonergic phenotypes, including whole blood serotonin levels and serotonin receptor sensitivity. RESULTS: One consistent phenotype between the two strains was performance in the tube test for dominance, where mutant mice displayed a greater tendency to withdraw from a social encounter in a narrow tube as compared to wildtype littermate controls. On the B6 background, mutant pup ultrasonic vocalizations were significantly increased, in contrast to decreased vocalizations seen previously on the 129 background. Several phenotypes seen on the 129 background were reduced or absent when the mutation was placed on the B6 background, including hyperserotonemia, 5-HT receptor hypersensivity, and repetitive behavior. CONCLUSIONS: Our findings provide a cogent example of how epistatic interactions can modulate the impact of functional genetic variation and suggest that some aspects of social behavior may be especially sensitive to changes in SERT function. Finally, these results provide a platform for the identification of genes that may modulate the risk of ASD in humans

    Trade openness and bigger governments: The role of country size revisited

    No full text
    This paper revisits the question of why more open countries tend to have bigger governments. We replicate successfully the main results of Ram (2009), who rejects the role of country size as an omitted variable. However, several extensions advise against a hasty conclusion: The results differ substantially depending on the data source used, the timeframe considered, the countries selected, and the way variables are measured. Specifically, we employ newer versions of the Penn World Table (PWT 7.1 and 8.0), allowing us to both extend the number of observations and the timeframe. We find evidence for the claim that smaller countries do indeed have bigger governments, especially when using the PWT 8.0 data, and Ram (2009) findings might be driven by the specific dataset used (PWT 6.1) and the countries included in that sample. Finally, we also conduct quantile regression analyses to pin down at which point of the distribution the suggested relationships come out

    Sorting through global corruption determinants: Institutions and education matter – Not culture

    •Using (IV) BMA methods, we address model uncertainty in the determinants of corruption.•We find institutional and economic factors to matter but not unchangeable cultural attributes.•The rule of law, government effectiveness, urbanization, and women in politics lower corruption.•The extent of primary education also matters, especially in developing countries.•Results offer policy avenues as all meaningful determinants are policy-accessible. Identifying the robust determinants of corruption among cultural, economic, institutional, and geographical factors has proven difficult. From a policy perspective, it is important to know whether inherent, largely unchangeable attributes are responsible or if institutional and economic attributes are at work. Accounting for model uncertainty, we use Bayesian Model Averaging (BMA) to analyze a comprehensive list of 36 potential corruption determinants across 123 countries (covering 87 percent of the world population). The BMA methodology sorts through all 68,719,476,736 possible model combinations (236) in order to carve out the robust correlates. We then take a step toward alleviating endogeneity concerns in an Instrumental Variable BMA framework. Our results indicate that cultural factors are largely irrelevant, whereas particular economic and institutional characteristics matter. The rule of law emerges as the most persistent predictor with a posterior inclusion probability (PIP) in the true model of 1.00, whereas we find strong evidence for government effectiveness (PIP of 0.88), urbanization (0.85), and the share of women in parliament (0.80) as meaningful determinants of lower corruption levels. In developing countries, the extent of primary schooling enters as a powerful factor with a PIP of 1.00
