This paper presents and applies a stage-of-fabrication inventory model to the UK manufacturing sector. The model emphasises the interaction between input (raw materials and work-in-process) and output (finished goods) inventories. This interaction is an important empirical regularity and proves...

In this paper we present an approximation method to compute the reorder point s in a (R; s; Q) inventory model with a service level restriction, where demand is modeled as a compound Bernoulli process; that is, with a xed probability there is positive demand during a time unit, otherwise demand...

We review and interpret recent work on inventories, emphasizing empirical and business cycle aspects. We begin by documenting two empirical regularities about inventories. The first is the well-known one that inventories move procyclically. The second is that inventory movements are quite...

Manufacturers' finished goods inventories are less cyclical than shipments. This requires marginal cost to be more procyclical than is conventionally measured. In this paper, alternative marginal cost measures for six manufacturing industries are constructed. These measures, which attribute...

There is widespread disagreement on the quantitative contribution of news shocks to business- cycle fluctuations. This paper provides a simple identifying restriction, based on inventory dynamics, that tightly pins down the contribution of news shocks to business-cycle volatility. We show that...

In standard models wages are too volatile and returns too smooth. We make wages sticky through infrequent resetting, resulting in both (i) smoother wages and (ii) volatile returns. Furthermore, the model produces other puzzling features of financial data: (iii) high Sharpe Ratios, (iv) low and...

I propose an investment-based asset pricing model augmented with intangible capital and transient volatility shock. Already-acquired intangible capital and new R&D investment are complementary inputs in knowledge production. The distinctive evolutionary dynamics of intangible capital as opposed...

We decompose total disagreement about macro variables into the disagreement among optimists (i.e., forecasters whose forecast exceeds a certain threshold) and pessimists. Optimistic (pessimistic) forecasters tend to disagree more in good (bad) times. Pessimistic (optimistic) disagreement...
