Risk-sharing networks and insurance against illness

Most risk-sharing tests on developing country data are conducted at the level of the village; generally, the full risk-sharing hypothesis is rejected. This paper uses detailed data on all insurance networks within a village in Tanzania; networks are not clustered but largely overlapping. We test whether full risk-sharing occurs within these networks. While village level full-insurance cannot be rejected for food consumption, we find evidence consistent with at least partial insurance of non-food consumption via networks.     

Reason rules...: the utility of rationality and the rationality of utility

Almost every theory of human behavior is based upon some assumption of rationalty. Such an assumption is commonly believed to be necessary in order to distinguish rational behavior, which is, from non-rational behavior, which is not amenable to scientific investigation. This article presents a thorough re-examination of this assumption, an inquiry which turns out to raise all the central issues of both the methodology and the theory of behavioral inquiry generally. It leads to the somewhat surprising conclusion that the notion of rationality does not have any meaningful role to play in behavioral inquiry, and that there is no sense in distinguishing rational from non-rational or irrational behavior. It also shows that the generalization of the utility notion in terms of information makes it into a much more powerful and subtle tool of analysis than it commonly appears to be taken for.     

Welfare migration in Europe

The enlargement of the European Union has increased concerns about the role of generous welfare transfers in attracting migrants. This paper explores the issue of welfare migration across the countries of the pre-enlargement European Union and finds a significant but small effect of the generosity of welfare on migration decisions. This effect, however, is still large enough to distort the distribution of migration flows and, possibly, offset the potential benefits of migration as an inflow of mobile labour into countries with traditionally immobile native workers.     

A bargaining perspective on strategic outsourcing and supply competition

This article considers the outsourcing choice of a downstream firm with its own upstream production resources or assets. The novelty of the approach is to consider the outsourced function as involving resources consistent with the resource‐based view of the firm. From a bargaining perspective, we characterize a downstream firm's decision whether to outsource to an independent or to an established upstream firm. In so doing, the downstream firm faces a trade‐off between lower input costs afforded by independent competition, and higher resource value associated with those who can consolidate upstream capabilities. We show that this trade‐off is resolved in favor of outsourcing to an established firm. Copyright © 2008 John Wiley & Sons, Ltd.     

What Do Current Account Reversals in OECD Countries Tell Us About the US Case?

This study examines macroeconomic developments around reversals in current account deficits in 29 OECD countries over four decades and draws some inferences for the present US deficit. Estimates of a probit model indicate that the deepness of the deficit itself, absence of spare production capacity and a beginning real depreciation are factors that increase the likelihood of a current account reversal in the following year. For the US each of these three indicators of a reversal are now on, making a near reversal probable. Over the past 40 years half of the current account deficit reversals in the OECD area were followed by a recession in the countries concerned.
