Relating commodity prices to underlying inflation: the role of expectations
Temporary supply factors may boost some commodity prices?a drought in the Midwest can jolt food costs, or a conflict in the Middle East might propel oil higher. These, in turn, can increase the overall consumer price index (CPI) and the headline inflation rate. ; Because central bank anti-inflation measures sometimes take a long time to affect prices, policymakers don?t necessarily react to short-term fluctuations in headline inflation (an overall rate that?s not seasonally adjusted). In fact, the mandate of many inflation-targeting central banks is to aim to keep headline inflation at a ...

The effect of satellite entry on product quality for cable television
In vertically differentiated markets, the effects of firm entry are contingent upon whether incumbent firms can respond to entry by adjusting product quality in addition to simply lowering prices. Using market-level data, I estimate a structural model of supply and demand for subscription television that takes into account the endogeneity of quality choice. Using counterfactual analysis, I decompose the effect of satellite entry on existing cable into two components: the conventional price response and the effect of endogenous quality adjustments (measured by changes in programming content). ...

The multiple unit auction with variable supply
The theory of multiple unit auctions traditionally assumes that the offered quantity is fixed. I argue that this assumption is not appropriate for many applications because the seller may be able and willing to adjust the supply to the bidding. In this paper I address this shortcoming by analyzing a multi-unit auction game between a monopolistic seller who can produce arbitrary quantities at constant unit cost, and oligopolistic bidders. I establish the existence of a subgame-perfect equilibrium for price discriminating and for uniform price auctions. I also show that bidders have an ...

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.

Why small businesses were hit harder by the recent recession
Although both large and small businesses felt the sting of job losses during the 2007-09 downturn, small firms experienced disproportionate declines. A study of the recession?s employment effect on small firms suggests that poor sales and economic uncertainty were the main reasons for their weak performance and sluggish recovery?problems that affected large firms too, but to a lesser degree. Although a tightened credit supply constrained some small firms, weak consumer demand for the firms? products and services was a more pressing factor, reducing revenues and dampening new investment ...

Happy hour economics, or how an increase in demand can produce a decrease in price
The standard supply-and-demand model is typically an economist?s most important analytical tool, but in some situations it does not capture the features of interest. For example, during ?happy hour,? bars near workplaces sell a higher-than-usual quantity of alcoholic beverages at a lower-than-usual price. This practice makes little sense using the standard competitive model, but an alternative model?the model of monopolistic competition?provides the needed analytic framework. ; This article provides a step-by-step construction of a monopolistic competition model in which many firms each ...

Estimating demand elasticities in a differentiated product industry: the personal computer market
Supply and demand functions are typically estimated using uniform prices and quantities across products, but where products are heterogeneous, it is important to consider quality differences explicitly. This paper demonstrates a new approach to doing this by employing hedonic coefficients to estimate price elasticities for differentiated products in the market for personal computers. Differences among products are modeled as distances in a linear quality space derived from a multi-dimensional attribute space. Heterogeneous quality allows for the estimation of varying demand elasticities among ...
