International trade models typically assume that producers in one country trade directly with final consumers in another. In reality, of course, trade can involve long chains of potentially independent actors who move goods through wholesale and retail distribution networks. These networks likely affect the magnitude and nature of trade frictions and hence both the pattern of trade and its welf...

In a wide range of industries alternative electronic distribution channels may permit disintermediation of wholesalers and of retailers. In some cases manufacturers or primary service deliverers may be able to deal directly with their customers, while in other industries existing intermediaries may be able to withstand attempts to bypass them. Two illustrative industries — consumer packaged goo...

It is commonly observed that the demand rates of many consumer goods are auto correlated and are dependent on the price and inventory amount. It is believed that the distribution of demand is independent from time to time. But in real life the demand of goods is auto-correlated. The effects of dependency and autocorrelated demand are studied under a periodic review model. An adaptive order-up-t...

Abstract: We reappraise the significance of indeterminacy in overlappinggenerations models. In any of Gale’s examples of locally-indeterminate (nonlocally-unique) equilibrium, for instance, judiciously splitting each of Gale’s goods into 2 close substitutes restricts that indeterminacy to each period’s distribution of consumption between those substitutes. In particular, prices, interest rates,...

I investigate changes in the structure of trade of seventeen transition economies between 1996 and 2006, focusing on differences across three types of products – homogeneous goods, reference priced goods, and differentiated products. I examine shares of exports of each type of good, intensive and extensive margins, and the hazard of exporting. While there are cross-country differences in the di...

We propose an economic supply chain model that accounts for typical inefficiencies resulting from low visibility of the flow of consumer goods. Using realistic numerical input values for the model, we illustrate how the profit distribution among manufacturer and retailer changes as item-level RFID is used for different purposes along the consumer goods supply chain. Applying basic Game Theoreti...

This paper presents a simple North-South model of endogenous growth, based on learning by doing, which is consistent with the following empirical observations: (i) the price of investment goods relative to consumption goods has been falling for the last 40 years in most industrialized countries, (ii) poor countries are net importers of investment equipment and (iii) after a period of initial co...
