Recently, computer simulation, particularly agent-based modeling, has grown in popularity as a method to uncover macro patterns and developments that emerge from simple micro behavior. The present paper combines both techniques by using protocol analysis to uncover player strategies in an experiment and encoding those strategies in an agent-based computer simulation. In particular, Keynes’ (193...

We present a simple theoretical framework that integrates the notion of the natural or neutral interest rate, liquidity preference theory, and the monetary policy practice by modern central banks. We claim that this theory explains the conditions under which an economy will experience an aggregate demand deficiency problem within a modern institutional setting. Contrary to the predictions of th...

This note considers Tobin’s average Q in a framework where firms finance investment by equities and debt. The determination of its long-run equilibrium value Qo is based on positing equality of the loan rate and, adjusted for a risk premium, the return on equities. Qo can thus be characterized as a ratio of two rates representing the somewhat modified interest costs and profits of the firms. Th...

The model presented in this paper distinguishes an industrial and an agricultural sector within a developing economy. Environmental degradation results from the overexploitation of a renewable resource due to a common pool externality, which causes agricultural productivity to decline. The model considers a di erentiated peasantry where land ownership and savings behaviour di er across income c...

The paper puts forward a deterministic macrodynamic model of the business cycle that allows for sluggish price and quantity adjustments in response to disequilibrium on product and labour markets. Based on regular oscillations of two exogenous variables, 14 reaction coe cients are calibrated such that the cyclical patterns of the endogenous variables are broadly compatible with stylized facts. ...

Using a recursive empirical model of the real interest rate, GDP growth and the primary government deficit in the United States, I solve for the ergodic distribution of the debt/GDP ratio. If such a distribution exists, the government is satisfying its intertemporal budget constraint. One key finding is that historical fiscal policy would bring the current high-debt ratio back to its normal lev...

A challenge to models of equilibrium indeterminacy based on increasing returns is that required increasing returns for generating indeterminacy can be implausibly large and rise quickly with the relative risk aversion in labor. We show that unsynchronized wage adjustment via a relative wage effect can both lower the required degree of increasing returns for indeterminacy to a plausible level an...

The traditional view of growth and fluctuations implies that aggregate demand shocks result in only transitory departures from trend or “normal” output, which is determined exclusively by aggregate supply factors. Using a simple dynamic framework for a less-developed economy, a series of models is developed to show that aggregate demand can have a permanent effect on economic growth. It is show...

This paper explores implications of nominal rigidity characterized by a non-constant hazard function for aggregate dynamics. I derive the NKPC under an arbitrary hazard function and parameterize it with the Weibull duration model. The resulting Phillips curve involves lagged in‡ation and lagged expectations. It nests the Calvo NKPC as a limiting case in the sense that the e¤ects of both terms a...

Ito has applied the non-Walrasian regime switching methodology to the Solovian neoclassical growth model and discussed the occurrence of regimes of full employment, overemployment and underemployment and the different dynamical systems (to be patched up) these regimes give rise to. We shall show in this paper that nothing of this sort really characterizes Solovian growth with non market-clearin...
