Dot arrays are often used to study basic numerical skills across cultures, species and development. Researchers investigate the ability of subjects to discriminate between dot arrays, as a function of the ratio or distance between their numerosities. Such studies have contributed significantly to the number sense theory (i.e., that humans are born with the ability to process numerosities, and s...

When I read your term papers, I look for your ability to motivate your question using economic logic, your ability to critically analyze the past literature, and your ability to recognize empirical problems as they arise. In particular, it is important that your term paper demonstrates that you are more knowledgeable, analytic, and sophisticated about the economics of health or development econ...

Spatial ability predicts performance in mathematics and eventual expertise in science, technology and engineering. Spatial skills have also been shown to rely on neuronal networks partially shared with mathematics. Understanding the nature of this association can inform educational practices and intervention for mathematical underperformance. Using data on two aspects of spatial ability and thr...

In this paper, we aim at assessing Markov-switching and threshold models in their ability to identify turning points of economic cycles. By using vintage data that are updated on a monthly basis, we compare their ability to detect ex-post the occurrence of turning points of the classical business cycle, we evaluate the stability over time of the signal emitted by the models and assess their abi...

The important of the demographic dividend to East Asian economic growth is now widely recognized. During the last four decades of the 20 Century the working age populations grew much more rapidly than the dependent populations fueling growth in per capita income. Over the coming decades, however, demographic change is seemingly unfavorable. In the coming decades the working-age populations of m...

In earlier debates on economic development, the agricultural sector’s role was somewhat controversial. While dualistic models highlighted the importance of agriculture, the mainstream literature placed a greater emphasis on the creation of a modern industrial sector. Soon agriculture disappeared from the mainstream development literature to re-emerge recently with a variety of multiple-sector g...

In intraspecific F1 diallel hybrids of Gossypium barbadense L., the inheritance study traits plant height, boll weight, productivity, and 1000-seed with combining ability analysis took place in 2020–2022 at Institute Genetics Plant Experimental Biology, Academy Sciences, Uzbekistan. These polygenic traits’ showed different ways fine-fiber cotton hybrids. The height trait’s overdominance interme...

The standard socio-economic science model (SSSM) assumes very considerable cognitive powers on behalf of its individual agents. Agents are able both to gather a large amount of information and to process this efficiently so that they can carry out maximising behaviour. Criticisms of this approach are widespread, even within the discipline of economics itself. We set up agent based models in whi...
