This contribution offers a comparison between the economic crises of the late-1920s and the first energy crisis of the 1970s through an inquiry into the changing balance between the transnational supply of capital and domestic aggregate demand for fixed capital formation and consumer goods. Its...

In this work we develop an agent-based model where hysteresis in major macroeconomic variables (e.g. GDP, productivity, unemployment) emerges out of the decentralized interactions of heterogenous firms and workers. Building upon the model in Dosi et al. (2016, 2017), we specify an endogenous...

Long run neutrality restrictions have been widely used to identify structural shocks in VAR models. This paper revisits the seminal paper by Blanchard and Quah (1989), and investigates their identification scheme. We use structural VAR models with smoothly changing covariances for identification...

This paper argues that John Maynard Keynes had a targeted (as contrasted with aggregate) demand approach to full employment. Modern policies, which aim to close the demand gap," are inconsistent with the Keynesian approach on both theoretical and methodological grounds. Aggregate demand tends to...

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...

We develop a Keynesian cross analysis with a dynamic optimization setting that explains long-run stagnation caused by aggregate demand deficiency. We show that an increase in government purchases boosts GDP through a multiplier process, but the implication is quite different from the...

The current study examines the relationship between the world oil price and aggregate demand in a developing country, Ghana, via the interest rate channel by means of cointegration analysis. Results of the study indicate that oil price - by impacting the price level positively - negatively...

The main task of this work is to develope a model able to encompass, at the same time, Keynesian, demand-driven, and Marxian, profit-driven determinants of fluctuations. Our starting point is the Goodwin's model (1967), rephrased in discrete time and extended by means of a coupled dynamics...

We propose a microeconomic foundation of the multiplier effect and that of the consumption function using a dynamic optimization model that explains a shortage of aggregate demand and unemployment. We show that government purchases boost aggregate demand through a multiplier-like process but...

Successful economic development to a large extent derives from the mobilization of underemployed resources. Demand policy can play an important role. It is critical, however, to consider balance of payments constraints and to ensure an expansion of investment in the modern sector. A combination...
