Inefficient Markov-perfect equilibria (MPE) are prevalent in dynamic matching and bargaining games (DMBG). I observe this inefficiency is caused by a substantial friction commonly assumed in the literature: players must exit the market after trading once. In response, this paper studies a simple...

Gale and Sabourian (2006) discuss the existence of inefficient Markov-perfect equilibrium (MPE) in a heterogeneous market. This paper shows that the example they provide cannot be supportedas a MPE. Indeed, with two buyers and two sellers, the dispersion of bargaining positions is not...

This paper presents a dynamic general equilibrium approach to analysing recent policy proposals on a resolution fund for direct recapitalisation of banks financed by banks. The model incorporates endogenous risk inherent in any economic activity due to imperfect information and incomplete...

We analyze a model with two types of agents: standard agents and gurus, i.e. agents who have the ability to influence the other investors. Gurus announce their beliefs and act accordingly. Gurus are strategic: they take into account the impact of their announced beliefs on the other agents,...

We study a simple general equilibrium model in which investment in a risky technology is subject to moral hazard and banks can extract market power rents. We show that more bank competition results in lower economy-wide risk, lower bank capital ratios, more efficient production plans and...

This is the partial manuscript of a book developing the tools of nonstandard analysis, geared to applications in mathematical economics. It was written over the period 1993-2008. There is no plan to complete and publish it

We consider a small open Harris-Todaro(1970) economy with a rural foreign enclave and urban informal sector. We introduce consumption-efficiency relation to explain the simultaneous existence of informal sector and urban unemployment. The main objective of this paper is to analyse the effects of...

The highly mathematical nature of the Arrow-Debreu and other similar models of general equilibrium hide rather than elucidate the nature of equilibrium in a private property market economy where all factors of production may be purchased or rented. It is an empirical commonplace that the...

The paper seeks to lay out a stock-flow-based theoretical framework that provides a foundation for a general theory of pricing. Contemporary marginalist economics is usually based on the assumption that prices are set in line with the value placed on goods by consumers. It does not take into...

Consider a multi-sector general equilibrium model where firms have incomplete information about the returns to scale of their production and where that information is sequentially updated once real production is observed. What is the impact of this learning dynamics on the market-wise...
