This paper extends the income fluctuations problem to an economy with endogenous growth. In the present setup, individuals, instead of owning an stream of endowments, accumulate capital with an investment irreversibility constraint and face uninsurable idiosyncratic risks to the return to...

In this paper I examine whether a society can improve welfare by imposing a legal restriction to forbid the use of nominal bonds as a means of payments for goods. To do so, I integrate a microfounded model of money with the framework of limited participation. While the asset market is Walrasian,...

Entrepreneurship, by its very essence, concerns the theory of the firm --- the individual enterprise --- which in turn is the essential core of micro-economics. A major theme of this study, however, is to demonstrate the interaction of micro- and macro-economic phenomena: to show how such firms...

Central banks have consistently differentiated the return on the securities they have issued (money and national debt). In contrast, first best efficiency demands that these securities earn the same return: the return on capital. A self-financed central bank, without capital and taxes, cannot...

This is a comment on the work of Rocheteau and Wright (2005) who have recently introduced competitive search into monetary economics. We extend their work by eliminating the restriction that the fees market makers charge to enter a submarket must be either non-negative or identical for buyers...

In a path-breaking but largely overlooked study, published in a festchrift thirty years ago (1975), Herman Van der Wee provided a comparison of prices and real wages of building craftsmen in the regions of Antwerp and south-eastern England, from 1400 to 1700. To do so, he constructed a composite...

We study the effects of inflation in a competitive search model where each buyer's utility is private information, and where money is essential in facilitating trade. The equilibrium is efficient at the Friedman rule, but inflation creates an inefficiency in the terms of trade. Buyers experience...

In this paper we integrate the recent development in monetary theory with international finance, in order to examine the coordination between two currency areas in setting long-run inflation. The model determines the value of each currency and the size of each currency area without requiring...

In this lecture, I explain what the microfoundations of money are about and why they are necessary for monetary economics. Then, I review recent developments of a particular microfoundation of money, commonly known as the search theory of money. Finally, I outline some unresolved issues.

This paper addresses why it is beneficial for a society to restrict the use of nominal bonds as a means of payment for goods. The model has a centralized asset market and a decentralized goods market. Individuals face matching shocks that affect the marginal utility of consumption, but they...
