National, state, and local policy makers have increasingly focused their attention on policies toward economic growth, especially efforts to raise the rate of investment. Recent studies of economic growth have raised a debate over the role played by the investment rate in the long-run...

This paper examines the potential impact of artificial intelligence (A.I.) on economic growth. We model A.I. as the latest form of automation, a broader process dating back more than 200 years. Electricity, internal combustion engines, and semiconductors facilitated automation in the last...

General purpose technologies (GPTs) such as AI enable and require significant complementary investments, including co-invention of new processes, products, business models and human capital. These complementary investments are often intangible and poorly measured in the national accounts, even...

For over a century, economists and policy makers have debated the relative merits of bank-based versus market-based financial systems. Recent research, however, argues that classifying countries as bank-based or market is not a very fruitful way to distinguish financial systems. This paper...

What accounts for differences in output per capita and total factor productivity (TFP) across countries? Empirical evidence points to resource misallocation across heterogeneous production units as an important factor. We study misallocation in a general equilibrium model of establishment...

We formulate a version of the growth model in which production is carried out by heterogeneous plants and calibrate it to US data. In the context of this model we argue that differences in the allocation of resources across heterogeneous plants may be an important factor in accounting for...

Using data from the United Nations Comparison Project and the Penn World Table, we find that machinery and equipment investment has a strong association with growth: over l9&)?l95 each percent of GDP invested in equipment is associated with an increase in GDP growth of 1/3 a percentage point per...

The basic neoclassical growth model accounts well for the postwar cyclical behavior of the U.S. economy prior to the 1990s, provided that variations in population growth, depreciation rates, total factor productivity, and taxes are incorporated. For the 1990s, the model predicts a depressed...
