Using cointegration techniques, we estimate two models that capture the long-term relationship between Spanish prices and agricultural production. The models were estimated over Spanish agricultural data from 1970 to 2000, a period spanning Spain’s implementation of the Common Agricultural...

Vector autoregressions are used to model price transmission through the coffee processing chain, from producers to the world market and from the world market to consumers. A comparison is made of price dynamics against a backdrop of two very different market structures: pre-1989, producers...

The paper studies equilibria for economies with imperfect competition and non-convex technologies. Following Negishi firms maximise profits under downward-sloping perceived demand functions. Negishi's assumptions, in particular the assumption of a single monopolistic competitor in each market,...

The residential UK electricity market was opened for the first time in 1999, introducing choice of supplier, and about 40% of households changed supplier in the first four years. After three years price caps were removed. We review this process and assess the competitiveness of the market by...

Using unique retail and wholesale price data for 4,532 products carried by a major Midwestern grocery retailer, we find evidence of significant retail price rigidity during the Thanksgiving through Christmas holiday period relative to the rest of the year. We suggest that this pattern of holiday...

The paper demonstrates the effects that the largely ignored, phenomenon of subsistence farming can have on agricultural development in countries in transition. The problem of subsistence consists of the different economic behaviour of subsistence farms compared to commercial ones. The paper...

In most countries of Central and Eastern Europe the process of transition to market economy resulted in an increasingly subsistence type of agriculture. The extent of subsistence farming varies from one country to another, but the phenomenon is universally present. The very existence, yet...

We study item-pricing laws (which require that each item in a store be individually marked with a price sticker) and examine and quantify their costs and benefits. On the cost side, we argue that item-pricing laws increase the retailers’ costs, forcing them to raise prices. We test this...

We use store-level data to document the exact process of changing prices and to directly measure menu costs at five multi-store supermarket chains. We show that changing prices in these establishments is a complex process, requiring dozens of steps and a nontrivial amount of resources. The menu...

We combine two data sets to study price rigidity. The first consists of weekly time series of retail, wholesale, and spot prices for twelve products. These time series contain two exogenous cost shocks. We find that prices exhibit more rigidity in response to the second shock than the first. The...
