The phenomenon of key supply management (KSM) in business companies is far less investigated than the phenomenon of key account management (KAM) which beneficiates, both in practice and in an academic context, from a growing interest. This article is based on the empirical analysis of a sample of 10 international companies which have recently launched KSM programmes or are currently working on launching such programs. It examines the difficulties these companies come up against when implementing such programmes and proposes to organize these difficulties around three dimensions: 1) the difficulties in implementing real supplier portfolio approaches; 2) the narrow view of value co-creation with suppliers, and 3) the persistent lack of integration of the purchasing function with other internal functions within the company. The conclusion of the article is that KSM is far from being a mere symmetric phenomenon of KAM. Several implications are then discussed in relation to the implementation of KSM programmes within companies. 相似文献

The house money effect predicts that individuals show increased risk-seeking behavior in the presence of prior windfall gains. Although the effect’s existence is widely accepted, experimental studies that compare individuals’ risk-taking behavior using house money to individuals’ risk-taking behavior using their own money produce contradictory results. This experimental field study analyzes the gambling behavior of 917 casino customers who face real losses. We find that customers who received free play at the entrance showed not higher but significantly lower levels of risk-taking behavior during their casino visit, expressed through lower average wagers. This study thus provides field evidence against the house money effect. Moreover, as a result of lower levels of risk seeking, endowed customers yield better economic results in the form of smaller own-money losses when leaving the casino. 相似文献

This article provides a simple model that explains the choice between permanent and temporary jobs. This model, which incorporates important features of actual employment protection legislations neglected by the economic literature so far, reproduces the main stylized facts about entries into permanent and temporary jobs observed in Continental European countries. We find that job protection has very small effects on total employment but induces large substitution of temporary jobs for permanent jobs, which significantly reduces aggregate production. 相似文献

As the information relative to endowments, costs and preferences is dispersed among many agents, the quality of resource allocation
depends on the ability of markets to communicate information inside the economic system. Because information is transferred
through negotiation and transaction behaviors, the network of trading relations defines the channels through which it flows.
In the present study, we use new computational tools to analyze the performance of two wholesale trade institutions widely
used around the world: network trading and marketplace trading. Whilst network trading and marketplace trading disseminate
far fewer bits of information than a perfectly transparent benchmark market, they often manage to generate an allocation of
resources that is almost as good. In many cases, network trading proves more effective than marketplace trading (contrary
to a common preconception). This surprising performance of network trading is linked to a form of indirect arbitrage induced
by connections between networks. Implications for market design and public policy making are presented, along with prospects
for further research. 相似文献

For the last half century, trade theorists, development economists, and development practitioners have been calculating what
was claimed to be the shadow price of scarce foreign exchange. In fact, what they have been calculating is the social value
of the receipt of a unit of a numeraire good from abroad, typically obtained from real models. In our paper, we explicitly
deal with a model of a monetized economy, and we develop formulas for the social value of a unit of foreign currency, which,
in general, differ from the traditional formulas. 相似文献

Some economists use an export tax, which alters the domestic relative price of exports, to model a voluntary export restraint,
which is a restriction on the quantity of exports with restriction-induced rents accruing to the exporting country. Implicit
in this approach is the presumption that the two policies are equivalent. In a very general model that allows for a finite
number of goods and factors and intermediated goods and joint production, we demonstrate that, in general, this is, in fact,
not the case. Specifically, from the exporting country’s perspective, the real income effects of the two policies are nonequivalent. 相似文献

This article assesses the reasons that led a majority of French voters to reject the 29 October 2004 Treaty Establishing a Constitution for Europe. Their reasons are less connected with the Treaty itself than with a fear of loss of national sovereignty, immigration, and relocation of firms to European countries where the workforce is cheaper. 相似文献
