We study the time-varying effects of Tobin's q and cash flow on investment dynamics in the USA using a vector autoregression model with drifting parameters and stochastic volatilities estimated via Bayesian methods. We find significant variation over time of the response of investment to shocks...

Mainstream Macroeconomics has withdrawn completely from its remote origins in Keynes and Kalecki, replacing the principle of effective demand (P.E.D.) with supply economics, investment with savings, and dynamics with equilibrium as a norm This article discusses, in the event of Kalecki’s...

The nature of the non accelerating inflation rate of unemployment is analysed. The focus of our analysis is the role of aggregate demand and capacity in the context of the NAIRU. Two aspects of the relationship between the level of aggregate demand and the NAIRU are of particular significance....

Although large changes in real exchange rates have occurred during the past decades, the real implications of these movements remain an empirical question. Using detailed data from the United States, Canada, the United Kingdom, and Japan we examine the implications of exchange rates for time...

In this paper we derive a model of aggregate investment that builds from the lumpy microeconomic behavior of firms facing stochastic fixed adjustment costs. Instead of the standard sharp (S,s) bands, firms' adjustment policies take the form of a probability of adjustment (adjustment hazard) that...

Investment is often irreversible, in that installed capital has little or no value unless used in production. In the presence of ongoing uncertainty, an individual firm's irreversible investment policy optimally alternates short bursts of positive gross investment to periods of inaction, when...

We propose a stochastic control model to study corporate investment with generalized investment frictions, including investment lags and various of adjustment costs. We find that the dominance of the ``good news principle'' or ``bad news principle'' is determined by the joint effect of...

This paper analyzes the effects of changes in government expenditures on both a domestically produced and an imported good in an open economy based on intertemporal optimizing behavior. The dynamic adjustment is characterized in detail and the critical role played by the accumulating capital...

In a world of integrated capital markets, the price of credit — which I measure by short-term expected real interest rates — is determined to equate the world aggregate of investment demand to the world aggregate of desired national saving. I implement this approach empirically by...

Aggregate investment and consumption have heterogeneous cyclical implications on firm-level earnings and the cyclical earnings patterns are associated with future abnormal returns. Earnings cyclicalities give rise to an information channel through which anticipated changes in investment and...
