Which of the following statements about convergence hypotheses is most accurate?

选项：

A.Countries risk falling into a non-convergence trap if they do not implement necessary institutional reforms B.The neoclassical model allows for countries that start with high per capita income to grow faster and stay ahead of developing countries C.Investing in lower-income countries subject to club convergence should provide a lower rate of return than investing in higher-income countries

A Correct because countries may fall into a non-convergence trap if they do not implement necessary institutional reforms. For example, failure to reform labor markets has undermined growth in some European countries that have experienced weak growth in employment and high rates of unemployment over the last two decades. Certain institutional arrangements that initially enhance growth may later generate non-convergence traps if maintained too long. Import substitution policies enabled the Latin American countries to grow rapidly in the 1950s and 1960s but caused them to stagnate in the 1970s and 1980s.

B Incorrect because in contrast to the neoclassical model, which predicts that convergence should occur, it is the endogenous growth model that allows for countries that start with high per capita income and more capital to grow faster and stay ahead of the developing countries. If the externalities associated with knowledge and human capital are large, the higher-income country can maintain its lead through high rates of investment in these capital inputs.

C Incorrect because if convergence, and especially club convergence, does occur, investing in countries with lower per capita incomes that are members of the club should, over long periods, provide a higher rate of return than investing in higher-income countries. Convergence means that the rate of growth of potential GDP should be higher in developing countries that have made the institutional changes that are a precondition for growth and that enable these countries to become members of the convergence club. With higher long-term growth in these economies, corporate profits should also grow at a faster rate. Given the faster rate of growth in earnings, stock prices may also rise at a faster rate.
