Peak Phase

The Nigerian agricultural export sector has been through three different development phases: transition, peak, and de-agriculturalisation. Blending simple international trade theory with actual facts, this study supports the notion that production during the transition phase enjoyed a classical "vent for surplus" type of growth, involving increased utilisation of available factor inputs, which in turn produced increased per capita income. Coupled with the classical factors were several technological packages introduced to farmers in later years. These led to the attainment of output peaks mainly in the 1950s and 1960s. Finally. the study argues that the foundation for de-agriculturalisation was already laid during the peak phase when farmers were taxed heavily, and several agricultural projects were biased against them.

Hotelling initiated the use of spatial analogies in assessing market differentiation. In this paper, this line is followed to analyze differentiated international markets. Most of the economies in the world are arrayed as if they are a continuum of points of demand. In this paper, this continuum of demand points is partitioned into homogeneous segments by use of a classification algorithm that minimizes within-group variation. The criteria used for classifying are two indicators of market overlap that have been suggested as important by the new trade theory, proximity of gross national product (GNP), and proximity of per capita GNP. Several of the derived market partitions are compared with other classifications of international markets in the form of existing and planned geographically discriminatory trade arrangements.

Background: Large-scale and population-based studies of heart failure (HF) incidence and prevalence are scarce in China. The study sought to estimate the prevalence, incidence, and cost of HF in China. Methods: We conducted a population-based study using records of 50.0 million individuals ≥25 years old from the national urban employee basic medical insurance from 6 provinces in China in 2017. Incident cases were individuals with a diagnosis of HF (International Classification of Diseases code, and text of diagnosis) in 2017 with a 4-year disease-free period (2013–2016). We calculated standardized rates by applying age standardization to the 2010 Chinese census population. Results: The age-standardized prevalence and incidence were 1.10% (1.10% among men and women) and 275 per 100 000 person-years (287 among men and 261 among women), respectively, accounting for 12.1 million patients with HF and 3.0 million patients with incident HF ≥25 years old. Both prevalence and incidence increased with increasing age (0.57%, 3.86%, and 7.55% for prevalence and 158, 892, and 1655 per 100 000 person-years for incidence among persons who were 25–64, 65–79, and ≥80 years of age, respectively). The inpatient mean cost per-capita was $4406.8 and the proportion with ≥3 hospitalizations among those hospitalized was 40.5%. The outpatient mean cost per-capita was $892.3. Conclusions: HF has placed a considerable burden on health systems in China, and strategies aimed at the prevention and treatment of HF are needed.

Per Capita

This paper evaluates income convergence in the European Union, between “old” (EU15) and “new” member states from Central and East Europe (CEE10), and among the countries within these two groups. The GDP per capita convergence should be expected according to the exogenous economic growth model and neoclassical trade theory. The presence of σ-convergence and both absolute and conditional β-convergence is tested for on a sample of 25 European Union countries (EU25). Results confirm the existence of β-convergence of GDP per capita at purchasing power parity among EU25, but not among EU15 and CEE10 countries. σ-convergence has been confirmed among EU25 and CEE10 countries, while GDP per capita has been diverging in the EU15 group of countries. Moreover, the results reveal that recent economic crisis has reversed long-term tendencies and led to income convergence within EU15 and divergence within CEE10. During the crisis, the income differences among the EU25 countries have increased, but the scope and duration of this effect has been limited and has not affected the long term convergence path. However, the obtained long term speed of convergence is significantly lower compared with the previous researches.
