Economic theory emerges through interaction among interested participants, with the content of those theories being a product of spontaneous ordering and not scientific planning. At any moment, it is reasonable to expect various theoretical formulations to be in play, some typically receiving...

Recursive relations for objects of statistical interest have long been important for computation, and remain so even with hugely improved computing power. Such recursions are frequently derived by exploiting relations between generating functions. For example, the top-order zonal polynomials...

We develop a dynamic political-economic theory of welfare state and immigration policies, featuring three distinct voting groups: skilled workers, unskilled workers, and old retirees. The essence of inter - and intra-generational redistribution of a typical welfare system is captured with a...

This paper develops a model of unemployment fluctuations. The model keeps the architecture of the Barro and Grossman (1971) general disequilibrium model but replaces the disequilibrium framework on the labor and product markets by a matching framework. On the product and labor markets, both...

This paper proposes a conceptualization of business cycle fluctuations in which the role of financial conditions and nonlinear dynamics are explicitly incorporated. We highlight the role of investment demand in driving economic fluctuations, consider its endogenous dynamic interactions with...

We propose an event-study research design to identify the nature and propagation of large unusual shocks in DSGE models and apply it to study the macroeconomic effects of the Covid shock. The initial outbreak is represented as the onset of a new shock process where the shock loads on wedges...

This paper examines the effectiveness of monetary aggregates through various nominal interest rates by integrating the financial sector into the Cash-in-Advance (CIA) economy. The model assumes that there are two types of representative agents in the financial sector, which are: productive banks...
