    Long-Term Economic Growth and Income Gaps


    Convergence May, 2024.


    We clarify the concept of convergence. This concept has been defined in many ways in growth theory and empirics. Recently, a rise in the poorer country income as a proportion of the richer country’s income has been called relative convergence, a decrease in the poorer country’s income short fall from the richer country’s income absolute convergence, and equality of the initially poorer country’s income to the richer country’s income that depends on the initial conditions full convergence We prove for continuous income changes the following: Relative convergence is a necessary but not a sufficient condition for absolute convergence and relative divergence is a sufficient but not a necessary condition for absolute divergence. We emphasize that fastergrowth is not sufficient for income gap reduction - it may take even 800/900 years of faster growth before income gaps start decreasing. Neo-classical growth theory has not used the phrases “relative convergence” or “full convergence” in describing convergence. Some seminal papers have used the phrase“absolute convergence” but given it the meaning that all countries’ incomes eventually become equal irrespective of initial conditions. We relate convergence concepts as defined above to the meaning other authors have given to “convergence” in growth theory since 1956.

    "Long-Run Catching-Up And Falling-Behind And Human Capital" May, 2024

    It has been recognized in the last 20-30 years that incomes rarely grow in a linear path over more than a decade. Weexamine the relative importance of catching-up in inputs and in the efficiency with which inputs are used in explaining catching-up in (relative) income. Using data as long as 64 years from one geographical region, Sub-Saharan Africa, we find growth miracles and failures may each last 20 to 30 years. We separate long-term catching-up growth periods from long-term falling-behind periods and examine
    proximate factors for the two. The main difference of the divergence panels from the r-convergence panels is on the role of human capital. When human capital is contributing to income, countries are catching up (in relative income) - and TFP is about one-half as important as human capital. When it is not, they are falling behind both relatively and absolutely.

    "EU Accession, Institutional Change, Growth and Human Capital" May, 2024


    We examine roles of initialinstitutions at transition and change in institutions upon joining the EU on incomes of European ex-socialist countries. The countries are divided in three groups: V4, Baltic and Slovenia (ELLS) andBulgaria and Romania, (B&R), ELLS had greater deterioration in institutions at transition. Using four EU15 countries as controls for DIDestimation, ATET is positive for all three groups and is greater for ELLS and B&R. The positive ATET is explained by greaterpost-accession contribution of human capital – the better skilled labor at transition needed the right institutions to create value it was capable of.

    "Long-Term Growth Miracles and Failures and Human Capital (PWT 9.1)" January, 2022.


    Therecent empirical growth literature has noted that most countries’ incomes do not grow uniformly over periods longer than a decade or so. We ignore the short-term, consider income variations over the long run (up to 65 years) and two growth regimes, and take growth relative to a numeraire country. The two regimes are: periods when a country’s income is catching-up (relative
    convergence) and when it is falling-behind (both relative and absolute divergence). To minimize parameter heterogeneity, we consider one geographical region, Sub-Saharan Africa (SSA). The average catching-up duration for this region is 19.4 years, average falling-behind is 28.1 years and the number of periods for the two experiences is almost the same. Performing growth accounting by panel estimation separately for the two sets of periods, we find when human capital is contributing to growth in a positive and statistically significant way, countries are catching-up; when it is not, they are falling behind. For the catching-up panels, we find total factor productivity (TFP) to be less important than human capital for both growth and income levels, and the excess-effect of human capital over TFP is about 2.5 times for growth than for income levels.
