We construct a general equilibrium New-Keynesian model in which firms differ in characteristics such as size, book value, sensitivity to market demand and degree of price stickiness. This establishes an explicit economic relation between firm level characteristics and the relationship between...

Empirical literature on investment and output dynamics is characterized by two robust stylized facts at the macro level. First, investment is considerably more volatile than output. Second, fluctuations of output and investment are highly synchronized. Furthermore, at the micro level, firm...

The empirical difficulties associated with estimating the effects of changes in interest rates and corporate tax policy on business fixed investment are often blamed on a lack of identification. In this paper, we study the effect of variation in interest rates on investment spending, employing a...

This paper studies the conditions under which new equipment may endogenously occur. To this end, we construct an endogenous growth multisectoral model with a preeminent new equipment sector. Technological progress is embodied: New machines can only be run on the most recent generations of...

This paper proposes a model of endogenous fluctuations in investment. A monopolistic producer has an incentive to invest when the aggregate demand is high. This causes a propagation of investment across sectors. When the investment follows an (S,s) policy, the propagation size can exhibit a...

We argue that the fiscal policies adopted early in World War I by the U.K. were responsible for its poor economic performance during the interwar period. In September 1915, the U.K. embarked on a set of non-tax-smoothing policies collectively known as the McKenna rule. The key dictum of the...

We construct a state space model for measuring real economic activity in real time (e.g., minute by minute) using a variety of stock and flow data, observed at mixed frequencies. Our data set comprises macroeconomic and financial variables: GDP, IP, unemployment, stock and bond market data, and...

On the one hand, recently a number of theoretical models have highlighted the role of credit market frictions in propagating and amplifying macroeconomic shocks. On the other hand, it still seems an open question whether this role is quantitatively significant. Our paper tries to fill this gap....
