Economic growth and convergence: Do institutional proximity and spillovers matter?

Abstract

This paper extends the existing studies on institutions-growth nexus in two ways: firstly, it estimates a growth model that is spatially augmented to capture the countries' dependence, and secondly it measures the countries' dependence using a newly proposed concept called institutional proximity, in addition to the commonly used geography. Spatial Durbin model, that includes not only spatially lagged dependent variable but also spatially lagged explanatory variables, is shown to be the most appropriate to describe the panel dataset used in this study, which comprises of observations from 58 developing countries for year 1984-2007. The results find that institutions, specifically the property rights institutions, matter for growth in developing countries. The results also find an evidence of indirect institutional spillovers where institutions in a country lead to growth improvement in the country and subsequently generate positive spillover effects on neighbors' economic growth. The results also yield robust support to the concept of augmented convergence process as a result of neighboring effects and its speed is relatively higher than the conventional β-convergence of a standard growth model. The greater convergence speed is consistent across a number of spatial models using both geographical and institutional proximity measures. The paper finally concludes with several policy implications for developing countries as far as the effects of institutional proximity and spillovers on growth and convergence are concerned.

Does social media promote democracy? Some empirical evidence

“…His findings indicate that democracy becomes stronger with increases in GDP per capita, educational attainment, as well as decreases in the gender gap in primary schooling attainment. 7 On the other hand, a greater urbanization and a greater reliance on natural resources have negative effects on democracy.…”

Geographic proximity, trade and economic growth: a spatial econometrics approach

“…Geographical matrix naturally assumes that the countries located closely would have a greater weight, or more spatial dependence between them, compared to countries located at a greater distance. The advantage of the geographical matrix is that it is unambiguously exogenous to the model, and therefore eliminates the problem of identification and causal reversion (Ahmad and Hall 2017). In the matrix N × N (N number of the countries), if countries were situated in near proximity to each other, then number one was used and for all other cases zero was used.…”

“…They do not affect each other in neoclassical exogenous growth models. However, the assumption that economies are independent from each other no longer holds as technological transfers, knowledge diffusions, labour migrations, institutional spillovers, contagious economic crises testify to the fact that economies are indeed 'interacting' with each other, or in spatial terms, they are actually spatially dependent (Ahmad and Hall 2017). In this case, the assumption of the neoclassical model of Solow and Swan (1956) is not established.…”

Does Population Mobility Contribute to Urbanization Convergence? Empirical Evidence from Three Major Urban Agglomerations in China

“…In 1986, Baumol and Abramovitz applied this theory to empirical research [20,21], regional convergence has gradually become an important topic. Currently, the studies of convergence and divergence mainly focus on economic growth, income, consumption expenditure, energy intensity, housing prices, and unemployment [22][23][24][25][26][27][28][29][30][31][32], and the types of convergence are various, including σ convergence (reflecting a decreasing trend of the urbanization level gap between regions or countries over time), β convergence (convergence only after controlling the factors affecting steady state), club convergence (convergence within subsamples), and stochastic convergence (examining whether the initial deviations from some hypothetical long-term equilibrium of an investigated indicator decrease over time). Correspondingly, the methods of measuring convergence are also different, such as CV sigma-convergence and beta-convergence, club convergence approach, Markov chain and spatial Markov chain methods, and econometric approach.…”
