We develop a model of unforeseen contingencies. These are contingencies that are understood by economic agents — their consequences and probabilities are known — but are such that every description of such events necessarily leaves out relevant features that have a non-negligible impact on the parties’ expected utilities. Using a simple co-insurance problem as backdrop, we introduce a model whe...

We analyze the problem of optimal monopoly pricing in social networks in order to characterize the influence of the network topology on the pricing rule. It is shown that this influence depends on the type of providers (local versus global monopoly) and of externalities (consumption versus price). We identify two situations where the monopolist does not discriminate across nodes in the network ...

This paper explores the link between boundedly rational behavior and incomplete contracts. The bounded rationality of the agents in our world is embodied in a constraint that the contracts they write must be algorithmic in nature. We start with a definition of contract incompleteness that seems both appealing and widely applicable. Our first task is then to show that, by itself, the algorithmic...

abstract the purpose of this paper is to test the hypothesis first proposed by romer (1993); suggesting that inflation is lower in more open economies. according to this hypothesis, central banks have a lower incentive to engineer surprise inflations in more-open economies because the phillips curve is steeper. furthermore, comparing with other empirical studies, this paper has used the new kof...

This paper contains a model of waste elimination through design. It argues for the importance of managing design complexity in improving cost, quality, variety, and time{to{market performance variables. Management of design complexity is identi ̄ed with creation, choice, and application of design problem representations, divisions of design labor, and product architectures that provably eliminat...

The Journal of Economic Literature codes classification system (JEL) published by the American Association (AEA) is de facto standard for research literature in economics. JEL used to classify articles, dissertations, books, book reviews, and working papers EconLit, a database maintained AEA. Over time, it has evolved extended with over 850 subclasses. This paper reviews history development sys...

Financial markets are a paradigmatic case of complex adaptive systems. However, their complexity cannot be captured by traditional modelisation paradigms and we thus need to turn to new modelling tools. We present agentbased simulation as the suitable paradigm to analyse financial markets: this method allows to study the market macro behaviour on the basis of its microstructure, and some advanc...

We prove an asymptotic revenue equivalence among weakly asymmetric auctions with interdependent values, in which bidders have either asymmetric utility functions or asymmetric distributions of signals.

abstract research and development (r&d;) spending plays a major role in innovation, raising productivity and increasing economic growth. the purpose of this paper is to investigate the impact of r&d; spending on growth and total factor productivity (tfp) in iran's agricultural sector. we estimate growth and productivity models using auto-regressive distributed lag (ardl) approach and data over ...

o ne of the effective strategies for economic development of clusters is the conduct of networking activities by cluster members. indeed, the majority of cluster members are micro and small enterprises, so, should attempt to overcome their inherent constraints and influence the market through networking activities. in addition, these enterprises lack an intra-firm research and development unit ...
