We introduce a new suite of macroeconomic models that extend and complement the Debt, Investment, and Growth (DIG) model widely used at the IMF since 2012. The new DIG-Labor models feature segmented labor markets, efficiency wages and open unemployment, and an informal non-agricultural sector....

Does greater product market competition improve external competitiveness and growth? This paper examines this question by using country-and firm-level data for a sample of 39 sub-Saharan African countries over 2000-17, as well as other emerging market economies and developing countries, and...

We provide an overview of the theories and empricial evidence on the complex relationship among innovation, competition, and inclusive growth. Competition and innovation-led growth are critical to drive productivity gains and support broad-based growth. However, new technologies and trends in...

We examine one of the most important and intriguing puzzles in economics: why it is so hard to find a robust effect of aid on the long-term growth of poor countries, even those with good policies. We look for a possible offset to the beneficial effects of aid, using a methodology that exploits...

The sizable hoarding of international reserves by several East Asian countries has been frequently attributed to a modern version of monetary mercantilism-hoarding international reserves in order to improve competitiveness. From a long-run perspective, manufacturing exporters in East Asia...

The carbon tax is a major instrument for curbing greenhouse gas emissions that cause global warming. Yet its adoption has been limited because of concerns over its effects on economic growth, income distribution, and international competitiveness. The paper shows that policymakers can minimize...

This paper examines the effects of demographic dynamics on the measured rates of economic growth. First, it develops a model of production with labor productivity that varies with age. Second, it uses macroeconomic and demographic data to estimate the relative productivity of different age...

This paper analyses the impact of government tax and subsidy policy on immigration of human capital and the effect of such immigration on growth and incomes. In the context of a two-country endogenous growth model with heterogeneous agents and human capital accumulation, we argue that human...

The present paper takes a fresh theoretical and empirical look into the relationship between Wagner’s law and economic development. It introduces human capital into a classic two-sector model of unbalanced growth. It shows that, as an economy develops, changes in the relative returns to human...

This paper addresses the growth, welfare, and distributional effects of credit markets. We construct a general equilibrium model where human capital is the engine of growth and individuals differ in their education abilities. We argue that the existence of credit markets encourages...
