How can national income be adjusted to indicate welfare improvement if the future is uncertain? The present paper extends the definition of national income to stochastic settings on the basis of discounted utilitarian welfare function. Real interest rate of consumption is redefined so that real...

Although the determinants of income are complex, the results are surprisingly uniform. To a first approximation, top incomes follow a power-law distribution, and the redistribution of income corresponds to a change in the power-law exponent. Given the messiness of the struggle for resources, why...

We present an application of the Dynamic Programming (DP) and of the Maximum Principle (MP) to solve an optimization over time when the production function is linear in the stock of capital (Ak model). Two views of capital are considered. In one, which is embraced by the great majority of...

The theoretical literature has predicted that inequality affects long-run growth by reducing human and physical capital, particularly in the presence of imperfect credit markets and other contractual frictions. We test these four mechanisms using measures of inequality at the country-level,...

I estimate a dynamic stochastic general equilibrium model to investigate the effects of capital-embodied technological progress on business cycle fluctuations, highlighting the role of economic obsolescence. Against a temporary shock to capital-embodied technological progress, I find that...

This paper develops a search and matching model of mergers and acquisitions (M&A) and uses it to evaluate the implications of merger activity for aggregate economic outcomes. The theory is consistent with a rich set of micro-level facts on US M&A, including, e.g., sorting among merging firms, a...

We show that an increase in aggregate uncertainty-measured by stock market volatility-reduces productivity growth more in industries that depend heavily on external finance. This effect is larger during recessions, when financing constraints are more likely to be binding, than during expansions....

This paper reassesses the link between ICT prices, technology, and productivity. To understand how the ICT sector could come to the rescue of a whole economy, we extend a multi-sector model due to Oulton (2012) to include ICT services (e.g., cloud services) and use it to calibrate the...

Two alternative measures of demand adjusted capital input for the U.S. non-farm private business sector are derived and their differential impacts on the potential supply of output are compared to those obtained using the unadjusted index of capital input published by the Congressional Budget...

This study considers the Tobin's q of a ‘multi-product' firm with fixed capital goods. This modified version of Tobin's q includes a share of the fixed capital goods in a firm's investment. A firm in a developing economy, such as a South Korean chaebol, catches up the world frontier technology...
