Micro-level empirical evidence suggests that plant managers adjust production by utilizing capital along nonconvex margins. Existing models of the monetary transmission mechanism (MTM), however, assume that production units adjust output smoothly. The objective of this paper is to determine...

In most manufacturing industries output is adjusted in a lumpy way along three margins: shiftwork, weekend work, and closing a plant temporarily down. We incorporate such decisions into a dynamic general equilibrium model and study: (i) if such micro-level nonconvexities magnify business cycles;...

We show that in a canonical model with heterogeneous entrepreneurs, financial frictions, and an imperfectly elastic supply of capital, a fall in the interest rate has an ambiguous effect on aggregate economic activity. In partial equilibrium, a lower interest rate raises aggregate investment...

The paper describes a semistructural macrofiscal approach to simulating and forecasting macroeconomic policies. Our canonical model is adapted to Cambodia and we demonstrate its application with an illustrative scenario of macroeconomic effects of the Covid-19 pandemic. Complemented with...

At the outset of 2022, the South Korean economy sought to start anew, aiming to finally surmount the hurdles of COVID-19. Unfortunately, however, the economy is now confronted with an unprecedented level of uncertainty, as one unforeseen risk after another emerged over the course of 2022. These...

We show that firms' nominal required returns to capital (i.e., their discount rates) are sticky with respect to expected inflation. Such nominally sticky discount rates imply that increases in expected inflation directly lower firms' real discount rates and thereby raise real investment. We...

The first quarter (Q1) 2023 manufacturing overall composite index remains below the baseline (100), indicating that conditions remain unfavorable. In addition, indexes for all indicators dropped significantly from the previous quarter. Business conditions (77), sales (75), domestic demand (78),...

I start with income and wealth inequality data from the Congressional Budget Office (CBO) and Thomas Piketty, and propose approaches taken from science (for example, behavioral evolution theory,) that might be useful in explaining the data and forecasting future economic events. Using a modified...
