This paper provides an explanation for the secular increase in the price of services relative to that of manufactured goods that relies on capital accumulation rather than on an exogenous total factor productivity growth differential. The key assumptions of the two-sector, intertemporal...

For US postwar data, the paper explains central consumption, labor, investment and output correlations and volatilities along with output growth persistence by including a human capital investment sector and a variable physical capital utilization rate. Strong internal "amplication" results from...

In the last few decades, real GDP growth and investment in advanced countries have declined in tandem. This slowdown was not the result of weak demand (there has been no shift along the Okun curve), but of a decline in potential output growth (which has shifted the Okun curve to the left). We...

We propose a simple macroeconomic model with input-output sectoral linkages based on Acemoglu et al. (2016) to quantify how changes in aggregate demand due to additional income from household's remittances propagates through the network of input-output linkages in Sub-Saharan African countries....

This paper identifies a new mechanism leading to inefficiency in capital reallocation at theextensive margin when an economy experiences a sectoral boom. I argue that imperfectionsin the financial market and capital barriers to entry in the booming sector create amisallocation of managerial...

The paper discusses the impact and implications of Korean unification by setting up a two-region endogenous growth model. The numerical solutions are based on the formal analytical model, and have been calibrated so that they reflect the observed features of the North and South Korean economies....

This paper studies the impact on growth, welfare, and government debt of fiscal reform packages in a theoretical model drawing together three key features of the endogenous growth literature: (i) investment in technology (in the form of human capital) offsets diminishing marginal productivity of...

Standard New Keynesian (NK) models feature an optimal inflation target well below two percent, limited welfare losses from business cycle fluctuations and long-term monetary neutrality. We develop a NK framework with labour market frictions, endogenous productivity and downward wage rigidity...

We evaluate the direct employment effect of the public investment in key infrastructure—electricity, roads, schools and hospitals, and water and sanitation. Using rich firm-level panel data from 41 countries over 19 years, we estimate that US$1 million of public spending in infrastructure...

Wide-ranging structural reforms are underway in Italy, aimed at addressing key bottlenecks in the product and labor markets. Our analysis, based on the IMF's Global Integrated Monetary and Fiscal model (GIMF), attempts to quantify the potential gains to the economy from a comprehensive package...
