Since decade 80`s, colonies of illegal settlements began rapidly increasing in many urban areas of cities in Indonesia. During the decade, urban population living in slum areas was recorded about 54% of total urban population particularly in mega cities of Indonesia. Nonetheless, that percentage...

Walras' law is central to the formation of economic theory. For mainstream economics, it is a device for testing rigorousness and consistency of model-building; for heterodox economists, the refutation of Walras' law is key to understanding Keynes' revolutionary contribution to a new economic...

We study money creation and destruction in today's monetary architecture and examine the impact of monetary policy and capital regulation in a general equilibrium setting. There are two types of money created and destructed: bank deposits, when banks grant loans to firms or to other banks and...

We characterize the equilibrium and optimal resource allocations in a general equilibrium model of monopolistic competition with multiple asymmetric sectors and heterogeneous firms. We first derive general results for additively separable preferences and general productivity distributions, and...

Short lived arbitrage opportunities arise when prices adjust with a lag to new information. They are toxic because they expose dealers to the risk of trading at stale quotes. Hence, theory implies that more frequent toxic arbitrage opportunities and a faster arbitrageurs' response to these...

It is routine to demonstrate in the exchange economy framework that small changes of individual preferences and endowments always result in small changes of the derived excess demand functions as one should expect. Though being as desirable for reasons of the consistency of the whole approach,...

The present paper makes a contribution to fill in a gap left open by dynamic theory and evolutionary economics as well. While the "closed loop" dynamic theory has explanation power in analyzing evolving economic systems at the price of neglecting the possible occurrence of non anticipated...

We study the problem of assigning indivisible goods to individuals where each is to receive one object. To guarantee fairness in the absence of monetary compensation, we consider random assignments and analyse various equity criteria for such lotteries. In particular, we find that sd-no-envy (as...

This paper analyzes within a two-region endogenous growth model how different types of public policies affect the equilibrium spatial distribution of economic activity. Integration is modeled as a continuum and enables firms to access the public input of the respective other region. Given a...

We integrate individual power in groups into general equilibrium models. The relationship between group formation, resource allocation, and the power of specific individuals or particular sociological groups is investigated. We introduce, via an illustrative example, three appealing concepts of...
