We generalized the empirical analysis of the Solow growth model to account for country-specific heterogeneity, relaxing the common assumption that all countries have identical aggregate production functions. Our analysis revealed significant country-specific variations in Solow parameters linked to differences in initial income levels.

We aimed to enhance the explanatory power of the Solow growth model by incorporating country-specific factors. This approach allows for a more accurate representation of the diverse economic environments across different countries.

Recognizing and incorporating country-specific heterogeneity in growth models improves their explanatory value and accuracy. This enhanced model provides better insights into the economic growth processes of individual countries, leading to more tailored and effective economic policies.

We provide a perspective on why interactions-based models represent a natural and powerful language for studying economic and related phenomena for fellow economists as well as the broader community of social scientists.

Despite the advances in interactions-based methods in economics, their use in economic analysis is still in its infancy. Further, considerable skepticism exists in many quarters as to the utility of these methods.

Interactions-based approaches provide a powerful way of understanding various phenomena based on the collective behaviors of a group of interacting, heterogeneous agents. We believe that a common general structure underlies such apparently different problems as the level of out-of-wedlock births, the agglomeration of firms in particular regions, and the diffusion of technologies.

We survey recent efforts to study the interrelationship between group and individual behavior by addressing several methodological questions

Social economics research melds together ideas traditionally pursued separately in economics and sociology. Sociology conceptualizes the role of social influences on individual preferences and cognition. Economics provides methods to model aggregate behavior as the outcome of individual decisions. This new social economics promises to provide new insights into social and economic dynamics.

The new social economics brings a richer view of human behavior and human interactions to the analysis of economic phenomena.

We provided an alternative perspective on ways to examine economic growth data with econometrics.

Few of the empirical studies of economic growth adjudicated the substantive differences between economic theories.

For over 15 years, substantial academic research has examined economic growth, yet many disparities exist between the theoretical perspectives on economic growth and empirical studies.
