Did speculation drive oil prices? market fundamentals suggest otherwise
Oil market speculation became an especially popular topic when the price of crude tripled over 18 months to a record high $145 per barrel in July 2008. Of particular interest to many is whether speculators drove oil prices beyond what fundamentals would have otherwise justified. We explore this issue over two Economic Letters. In this article, we look at evidence from the physical market for oil and conclude that fundamentals, and not speculation, were behind the dramatic rise and fall in oil prices. In our companion Economic Letter, we examine the futures market.
Working Paper
Market run-ups, market freezes, and leverage
The authors study trade between a buyer and a seller when both may have existing inventories of assets similar to those being traded. They analyze how these inventories affect trade, information dissemination, and price formation. The authors show that when the buyer's and seller's initial leverage is moderate, inventories increase price and trade volume, but when leverage is high, trade may become impossible (a "market freeze"). Their analysis predicts a pattern of trade in which prices and trade volume first increase, and then markets break down. The authors use their model to discuss ...

Recent evidence on the muted inventory cycle
Inventories play an important role in business cycles. Inventory build-ups add momentum to the economy during expansions, while inventory liquidations sap economic strength during recessions. In addition, because inventory fluctuations are notoriously difficult to predict, they present considerable uncertainty in assessing the economic outlook.> The role of inventories in shaping the current outlook for the U.S. economy is particularly uncertain. In the early 1990s, inventory swings appeared less pronounced than usual, leading some analysts to conclude the business cycle might now be more ...

Market run-ups, market freezes, inventories, and leverage
This paper is superseded by Working Paper No. 13-14.> We study trade between a buyer and a seller who have existing inventories of assets similar to those being traded. We analyze how these inventories affect trade, information dissemination, and prices. We show that when traders? initial leverages are moderate, inventories increase price and trade volume (a market ?run-up?), but when leverages are high, trade is impossible (a market ?freeze?). Our analysis predicts a pattern of trade in which prices and volumes first increase, and then markets break down. Moreover, the presence of competing ...

The great trade collapse of 2008-2009: an inventory adjustment?
This paper examines the role of inventories in the decline of production, trade, and expenditures in the US in the economic crisis of late 2008 and 2009. Empirically, the authors show that international trade declined more drastically than trade-weighted production or absorption and there was a sizeable inventory adjustment. This is most clearly evident for autos, the industry with the largest drop in trade. However, relative to the magnitude of the US downturn, these movements in trade are quite typical. The authors develop a two-country general equilibrium model with endogenous inventory ...

The role of inventories in the business cycle
Changes in the stock of firms' inventories are an important component of the business cycle. In fact, discussion about the timing of a recovery following a recession often focuses on inventories. In "The Role of Inventories in the Business Cycle," Aubhik Khan surveys the facts about inventory investment over the business cycle, then discusses two leading theories that may explain these observations.

(S, s) inventory policies in general equilibrium
We study the aggregate implications of (S,s) inventory policies in a dynamic general equilibrium model with aggregate uncertainty. Firms in the model's retail sector face idiosyncratic demand risk, and (S,s) inventory policies are optimal because of fixed order costs. The distribution of inventory holdings affects the aggregate outcome in two ways: variation in the decision to order and variation in the rate of sale through the pricing decisions of retailers. We find that both mechanisms must operate to reconcile observations that orders are more volatile than, and inventory investment is ...

What inventory behavior tells us about business cycles
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 high-frequency productivity shocks to procyclical work effort, are more successful in accounting for inventory behavior. Evidence is also provided that the short-run slope of marginal cost arising from convexity of the production function is close to zero for five of the six industries. The paper concludes ...

End of the Road? Impact of Interest Rate Changes on the Automobile Market
The Federal Reserve has kept interest rates at historic lows for the last six years, but eventually rates will return to their long-term averages. That means both policymakers and the public will once again be asking one of the classic questions in monetary economics: What are the impacts of rising interest rates on the real economy? Our recent New York Fed staff report ?Interest Rates and the Market for New Light Vehicles,? considers this question for the U.S. market for new cars and light trucks. We find strong evidence that rising rates will dampen activity: Our model predicts that in the ...
